Abstract:
Abstract Based on the loss model of pulp pump set up in the I part of this research, an efficient designing method is proposed by taking account of the influences of head reduction by small blade number, leakage loss via tip clearance, and erosion-corrosion wears in pumps separately. Further, a two-stage optimal designing approach was proposed to tackle the oversized design. The pump designing was performed by coupling with a CFD-based optimization procedure. An efficiency increase of near 10 % was achieved on the pump model validated in laboratory. It was proved that performance could be improved by increasing the impeller blade width and enlarging the impeller blade outlet angle. It was further shown that the erosion-corrosion wear in pulp pump was relatively lighter when compared to particle-impingement wear in slurry and sewage pump. Adoption of composite material showed potential in energy-saving in the pumping system.

Abstract:
Pumps, especially centrifugal pumps, play an important role in engineering application, such as petroleum and petro-chemical industries, agricultural industries, portland cement industries etc. To obtain the best performance of the pumps, one has to operate the pumps at their design conditions. In some circumstances, however, the pumps must operate lower than their design conditions and result in the decrease in their performances. In such cases, it is possible to replace the pump impeller with the smaller impeller diameter or to cut its original impeller to smaller size as necessary. The cut of the impeller, or it is frequently referred to as impeller trimming, in some extence is preferable than replacing with new impeller or even by replacing with new pump with smaller head and capacity. In this study, we examine the effect of the pump impeller trimming to the pump performaces. The study was performed in the Fluid Mechanics Laboratory, Mechanical Engineering Department of ITS, Surabaya. The pump impellers were cut up to approximately 19 percent of its original pump impeller diameter, where the original pump impeller diameter is 129 mm. The pump has the maximum capacity of 100 liters/min and the total head of 31.5 m. The pump is powered by a 300 Watt electrical motor. Parameters to be studied in this research include pump capacity, pump head, pump power, and pump efficiency. The results of this study show that all data are in good agreement with the pump affinity laws. Pump capacity, pump head, and pump power decresase as the pump impeller diameter decreases. The pump efficiency is, however, in some extent, increases as the pump impeller diameter decreases. The maximum increase in pump efficiency is obtained when the ratio between the trimmed impeller to its original pump impeller diameter is approximately 89 percent (i.e. D2/D1 = 0.89), with the increase in pump efficiency of approximately 20 percent.

Abstract:
Abstract Nowadays, plunger high-pressure water pumps applied in large-scale mine are mostly used in coal mine hydraulics to increase permeability, and it is difficult to transport objections underground. Besides, the permeability improvement is affected during overhaul too. Therefore, multiple small high-pressure water pumps operating in parallel can be used to solve the problems mentioned above instead of large high-pressure water pumps. Moreover, the operating principle of the plunger high-pressure pump determines the specific flow fluctuation characteristics during its operation, and similar flow fluctuations also exist during the operating of parallel pump sets. The transmission model and AMESim hydraulic simulation model of single, parallel plunger pumps are established, taking the BQW-22/50 high-pressure water pump as an example. The operating characteristics of a single plunger pump and a parallel pump group are analyzed in this paper. The results are obtained as follows: the instantaneous discharge flow curve of a single plunger pump conforms to a sine function; the flow of the parallel pump set is the superposition of the flow of multiple plunger pumps; the instantaneous discharge flow curve changes under the influence of the phase deviation angle between the pumps; when parallel pump sets are running, there is an optimal phase deflection angle between the pumps, which minimizes the flow fluctuation of the pump sets; when four high-pressure water pumps are operated in parallel, the optimal phase deflection angle between the pumps is π/12 or π/4.

Abstract:
The aim of this article is to study the theoretical flowrate characteristics of the conjugated involute internal gear pump. The conjugated involute internal gear pump has a different internal gear, the profile of which is completely conjugated to that of pinion, from the conventional involute internal gear pump. To describe briefly, the former pump is called ‘conjugated pump’ while the latter pump ‘conventional pump’. This structure makes the conjugated pump have smaller volumes of trapped fluid than the conventional pump, which indicates the conjugated pump has a better flowrate performance. Although there have been numerous investigations into gear pumps, none of them have dealt with the conjugated pumps yet. This article presents a systematic study on the theoretical flowrate characteristics of the conjugated pumps. It is expected to obtain some generalized conclusions to guide the design of internal gear pumps. Firstly, a double envelope concept is applied to derive the mathematical models of the conjugated involute internal gear couple. Next, mesh characteristics of the gear couple, which mainly decide the fluid delivery performance of the pumps, are analyzed. Finally, using a control volume approach, the theoretical flowrate characteristics of the pump under different design parameters of gears are investigated. Results show the conjugated pump has a better performance than the conventional one. To design a conjugated pump with good flowrate characteristics, it’s feasible to choose a proper shifting coefficient, a larger tooth number of the pinion, a smaller tooth number of the internal gear, a larger pressure angle and a larger fillet radius, under the condition that no tooth interference occurs.

Abstract:
Piezoelectric pump design is regarded as a hot research topic in the microfluidic field, and has been applied in liquid cooling, precision machinery and other relevant domains. The valveless piezoelectric pump becomes an important branch of the piezoelectric pump, because it successfully avoids the problem of “pump-lagging of valve” during the valve piezoelectric pump processing. This paper summarizes the development of valveless piezoelectric pumps, and introduces some different configurations of valveless piezoelectric pumps. The structure and material of all kinds of valveless piezoelectric pumps are elaborated in detail, and also the output performance of the pump is evaluated and analyzed with the variations in flow rate and output pressure as reference. By comparing the flow of different types of valveless piezoelectric pumps, the application of valveless piezoelectric pumps is also illustrated. The development tendency of the valveless piezoelectric pump is prospected from the perspective of structure design and machining methods, which is expected to provide novel ideas and guidance for future research.

Abstract:
Background: When we use rotary blood pumps as an assist device, an interaction takes place between the pump performance and the native heart function (native heart influences pump performance and vice versa). The interaction between native heart and rotary blood pump can be useful to predict recovery of the failing heart. Methods: The rotary blood pumps used were microaxial catheter-mounted pumps with an external diameter of 6.4mm (Impella, Aachen, Germany). The pump-heart interaction was studied in five juvenile sheep with a mean body weight of 68.5 ± 8.7 kg. The pumps were introduced via the left carotid artery and placed in transvalvular aortic position. Recorded parameters were pump speed (rpm), generated flow (L/min) and differential pressure (mm Hg) obtained at high frequency rate of data recordings (25 sets of data per second). This allowed continuous analysis of the pump performance during cardiac cycle. Under clinical conditions the interaction was studied in a 60-year-old male, in whom the device was applied due to postcardiotomy heart failure after myocardial infarction. Results: Heart-pump interaction was analyzed based on pump flow differential pressure. This relationship, analyzed continuously during cardiac cycle, presents as a loop. The dynamic contribution of the heart to the flow generated by the pump leads to continuous fluctuation in the pressure head and the creation of hysteresis. The improved function of the failing heart under clinical conditions after seven days of mechanical support was expressed by: increased hysteresis of the loop caused by increased gradient of flow generated during cardiac cycle, a more pronounced ventricular ejection phase that indicates more dynamic heart contribution to the generated flow, and finally increased gradient of the differential pressure during cardiac cycle, caused predominantly by increased aortic pressure and decreased left ventricle pressure during diastolic phase. Conclusions: The heart-pump interaction based on the pump flow-differential pressure relationship can be useful in predicting the possibility to wean the patient from the device.

Abstract:
Successes of extracorporeal life support increased the use of centrifugal pumps. However, reports of hemolysis call for caution in using these pumps, especially in neonatology and in pediatric intensive care. Cavitation can be a cause of blood damage. The aim of our study was to obtain information about the cavitation conditions and to provide the safest operating range of centrifugal pumps. A series of tests were undertaken to determine the points at which pump performance decreases 3% and gas bubbles start to appear downstream of the pump. Two pumps were tested; pump R with a closed impeller and pump S with a semiopen impeller. The performance tests demonstrated that pump S has an optimal region narrower than pump R and it is shifted to the higher flows. When the pump performance started to decrease, the inlet pressure varies but close to −150 mmHg in the test with low gas content and higher than −100 mmHg in the tests with increased gas content. The same trend was observed at the points of development of massive gas emboli. Importantly, small packages of bubbles downstream of the pump were registered at relatively high inlet pressures. The gaseous cavitation in centrifugal pumps is a phenomenon that appears with decreasing inlet pump pressures. There are a few ways to increase inlet pump pressures: (1) positioning the pump as low as possible in relation to the patient; (2) selecting appropriate sized venous cannulas and their careful positioning; and (3) controlling patient’s volume status.

Abstract:
Although a method for the optimal design of ram pump systems using a pump of given size now exists, there is no simple procedure for selecting the proper size of pump to provide a specific duty. This Technical Note shows how pump size may be determined from the required output power. The finding is supported by existing results and further tests on a 53 mm Wilcox pump. Examples are given to illustrate the sizing of small to medium pumps. A cost analysis indicates that economy of scale applies to ram pumps and that the use of multiple pumps is not cost effective unless low drive heads have to be utilized.

IntroductionInsulin pump access in type 1 diabetes may be inequitable. We studied the association between government funding programs for insulin pumps and rates of insulin pump use and disparities between pump users and non-users.Research design and methodsAdults with type 1 diabetes were identified in the National Diabetes Repository, a primary care electronic medical record database of individuals with diabetes from five Canadian provinces. Proportions of individuals using insulin pumps were compared between provinces with and without pump funding programs. Multivariable logistic regression models were used to estimate the odds of insulin pump use adjusting for confounders. Univariate logistic regression models were used to estimate the odds of insulin pump use according to each predictor, according to pump funding program status.ResultsOf 1559 adults with type 1 diabetes, proportions using insulin pumps were 47.8% (95% CI 45.1% to 50.5%) and 37.7% (95% CI 31.5% to 44.1%) in provinces with and without pump funding programs (p=0.0038). Adjusting for age, sex, HbA1c, income quintile, and rural/urban location, the OR for insulin pump use was 1.45 (1.08–1.94) for provinces with pump funding programs compared with provinces without. Higher income was associated with a greater odds of insulin pump use in provinces with pump funding programs, and rural/urban location was not associated with insulin pump use.ConclusionsInsulin pump use is more common in regions with government funding programs. Further research is required to best understand and comprehensively address persistent income disparities between pump users and non-users despite the availability of reimbursement programs.

Abstract:
With increasing energy costs and competitive pressures, interest has increased in surveying installed pumps for potential energy savings. Field pump efficiency tests are required to assess pumping performance and help to identify improvement opportunities. This work concerns the on-site measurements of pulp-suspension pumping efficiency. This involves the measurement of pump head, flow rate and power consumption. Provided that consistent flow measurements are available, it is possible to reliably and non-invasively measure actual pump system efficiencies in pulp suspension flow, with a minimum process disturbance. As part of a most appropriate measurement-procedure study, four portable nonintrusive flow meters were evaluated on site for pulp suspension flow. The Fast Fourier Transform Doppler was found to be the most suitable for a pulp mill pump survey. Efficiency measurements were performed on six pump systems with motors between 100 and 700 HP. It is shown that as-installed pump efficiency can be used to help predict the degradation of the pump and also its effect on the pumping system’s operation. A system approach analysis was performed in each case, which can be effective in assessing system performance and finding potential enhancements. The use of variable speed drives allows the operating point to move along the system curve, requiring less energy to drive the pump. VSD of larger motors are expensive and their profitability compared to other modification alternatives should always be carefully checked by calculations based on accurate on site measurements and life cycle costs. Finally, in this survey of six pump systems, significant potential savings of around 30% of present power consumption were found.

Abstract:
The interest for power and energy measurement has greatly raised with todays increasing electricity prices and enviromental awareness. In the search for energy efficient solutions, the measurements are more complex due to increasing of non linear components. Harmonics and non sinusoidal voltages put high demands on sampling and filtering. Meanwhile, the price must be controlled so the customer still will find it interesting to invest in smaller plants. ITT W&WW asks for a robust, heat resistant power meter with compact dimensions to allow mounting inside the casing of a pump. It should be able to measure the power, both from a regular power supply and fed from a VFD. The accuracy needs not to be on reference level, but the price/performance-ratio is an important parameter. Synchronous sample is tested, but is not considered suitable. Several test kits designed for 50 Hz AC, turn out to also measure VFD feed loads with good accuracy.

Abstract:
Mycronic is a company that manufactures a solder paste printer used to manufacturecircuit boards. Inside the printer solder paste is fed with the help of a screw pump.The solder paste, consisting of relatively soft metals has a tendency to stick to thescrew surface and form particles. These are then detached and passed on in thesystem and can clog the nozzle of the printer. This project investigated the possibilityof creating a model test where different parameters can be varied to evaluate itsinfluence on the amount of solder paste sticking to the surface of the screw. Testingthese parameters directly in the solder paste printer would be time consuming andexpensive.A pin-on-disk set up with some modified parts was used to emulate the solder pastemotion in the screw pump. The results were then analyzed in light optical microscope(LOM) and scanning electron microscope (SEM) equipped with energy dispersivex-ray spectroscopy (EDS).The parameters that were varied were pressure, temperature, rotation speed,substrate, content of the paste and the shape of the profile, which is supposed toemulate the ridge of the screw. It was shown that the profile shape, the substrate andthe pressure was of great importance in the deformation of the solder balls while therotation speed and the paste content had a small or no effect.The goal of the project is to recreate the agglomerates that have led to malfunctionsin the printing and evaluate which parameters that have the greatest significance.

Abstract:

Målet med det här projektet är att bygga ett tillförlitligt pumpsystem som inte är beroende av elektricitet eller icke förnyelsebara bränslen. Pumpen ska klara att pumpa 50-100 liter per dygn till en höjd av 10 meter. Konstruktionen ska placeras i indianbyn El Vergel i Amazonas, Colombia. Pumpen ska pumpa orent vatten till vattenreningstunnor de månader som invånarna i byn inte har tillgång till regnvatten.

Olika koncept arbetades fram och utvärderades. Det som valdes var en cykeldriven vattenpump, vilken uppfyllde alla krav.

Pumpens axel är kopplad till bakhjulets fälg med en kilrem. När tramporna snurrar så överförs kraften från det främre kugghjulet till det bakre med cykelkedjan och sen med kilremmen från fälgen till pumpaxeln. Konstruktionen är enkel och den är lätt att laga om den går sönder. Resultaten är en tillförlitlig pump som pumpar med ett jämt flöde.

Abstract:
This study aimed at refining and improving current methodology concerning large-scale heat pump performance. This study was performed on two large-scale ground source heat pumps located in Solna (Stockholm). These were connected to an aquifer thermal energy storage system which provided heating and cooling for two office buildings. The heat pumps had been equipped with preliminary sensors from the BMS (Building management system) and been in operation since 2016. In 2019, additional detailed measurement equipment from ClimaCheck was installed to collect comprehensive data from the heat pumps to allow a more comprehensive performance evaluation. This study was primarily performed by data pre-processing of the BMS-data and the ClimaCheck-data. Once this was done, the ClimaCheck parameters were backtracked and recalculated. Subsequently new models for system evaluation was implemented. The most desired parameter to replace in the ClimaCheck model was the mass flow rate, which they obtain though an energy balance over the compressors. The latter part of the study was to see whether the BMS had sufficient data to provide the same information as ClimaCheck. This was done by implementing a regression of the BMS-data, where the heating and cooling capacities from ClimaCheck were used as targets. The results from the study showed that implementing a mass flow rate based upon compressor efficiency instead of an assumed heat loss was difficult and only reliable for higher loads. When evaluating the ClimaCheck parameters, interesting results were found concerning their calculations for the heating capacity, which might not be calculated the way they express in their formulas. The regression from the BMS-data was proven difficult because of the insufficient and lacking data for some instances. Five different models were produced and compared, some models showed accuracy up to 95% depending on the desired metric. It can be concluded that it is possible to estimate the key performance indicators using the BMS-data. It yields good results for the COP’s and very accurate results for the SPF’s over a year. This makes it possible to evaluate the heat pump performance for years prior to the installation of the ClimaCheck system.
I den här studien analyseras metodiken för att bestämma prestandan hos industriella värmepumpar. Studien utfördes i Solna utanför Stockholm på ett värmepumpsystem som är kopplat till en grundvattenkälla. Systemet tillförde uppvärmning och kylning till tv˚a kontorsbyggnader. Systemet har varit i drift sedan 2016 och i samband med installation s˚a sattes sensorer upp f¨or att kontrollera systemet. Dessa sensorer ¨ar kopplade till bygnadernas BMS, som är utvecklat av Siemens. I början av 2019 anlitades företaget ClimaCheck för att installera ytterligare ett mätsystem, så att värmepumparnas prestanda kunde analyseras. Denna studie utfördes endast på värmepumparna som bara utgjorde en liten del av hela systemet. Till en början fokuserade studien på analys och databehandling av all data, både på datan från Siemens och ClimaCheck. Med hjålp av den uppmätta ClimaCheck-datan verifierades sedan ClimaChecks metod, genom att implementera ClimaChecks beräkningar i python. Detta gjordes primärt för att både kunna verifiera och sedan kunna implementera en möjlig förbättring i massflödet som ClimaCheck använder i sin modell. Sedan gjordes flera regressionsmodeller med BMS variabler, där targetvariablen sattes till antingen ClimaChecks beräknade värmeeffekt eller kyleffekt, beroende på vilken av dem som analyserades. Anledningen till detta var att BMS-datan inte innehåller de mätpunkter som krävs för att teoretiskt bestämma kapaciteterna. När det nya mass flödet introducerades blev resultatet inte önskvärt och den nya modellen var bara tillämpbar då värmepumparna gick på max effekt. När ClimaChecks beräkningar och parametrar återskapades hittades intressanta resultat angående värmekapaciteten. Den gick inte att återskapa med deras enthalpiberäkningar, utan den hittades istället med en annan metod. Regressionen som gjordes gav goda resultat om man bortser från vissa antaganden som gjorts. Regressionen kunde beroende på vilken parameter som efterfrågades ha en noggrannhet på upp till 95%. Studien visar att ClimaCheck har en bra och fungerande modell men den kan förbättras. Den tar även upp hur viktigt det är med data för att ordentligt och effektivt kunna utvärdera system. Slutligen kommer studien åskådliggöra en god metodik för hur data kan hanteras och tillämpas. Systemutvärdering är av yttersta vikt för att reducera energikostnader och många system skulle behöva utvärderas.

Abstract:
Pump sump designs play an important role for vertical pumps since they are responsible for the flow conditions at the impeller inlet. To first foresee and then prevent possible damages resulting from uneven flow conditions, computational fluid dynamics (CFD) can support model tests to reduce at least costs, but, with increasing computer power, also time. This paper compares different approaches to model the flow in pump sumps: The conventional single phase fixed water surface method and the multiphase (air+water) free water surface method. Both methods are compared with unsteady state computations and two different geometries (original and modified geometry) regarding differences in water surface, flow distribution in the pump wells, measurements, and computational time. All CFD results compare well with the experiments and are in good agreement with the vortex formation, type, and location as well as flow pre-rotation. Most of the time, the main interest lies in flow, vortices, forces, and frequencies in the attached pump, and additional computations need to be undertaken. Due to different timescales between the flow in the pump sump and in the pump itself, a decoupled technique is conventionally used in which firstly the flow field of the sump and secondly in the vertical pump is computed. We compare this decoupled method with a fully coupled one regarding computational time needed and time discretisation required as well as resulting flow structures and radial forces. Results of both methods are mainly in a good agreement, show slight differences in the velocity profile at the impeller inlet, and larger ones in magnitude of radial forces and force modulus. Decoupled and coupled method show practically the same computational effort, which recommends the application of the fully coupled approach not only in special cases where the vortices in the sump are triggered by the impeller rotations, especially at low flow rate operating points and existence of pre-swirl vortices.

Abstract:
The design criteria of rotodynamic pumps with optimal efficiency have been covered widely in the literature for many years, however little attention has been given to hydraulic design of centrifugal fire pumps. Fire pumps have different design objectives than commercial pumps. Cost effective design solutions for fire pumps require a more comprehensive analysis of pump performance characteristics in order to achieve the desired curve shape while minimizing the driver size. Computer-aided design (CAD) and Computational-Fluid Dynamics (CFD) analyses of pump hydraulic components have been performed for several decades, and today they are highly sophisticated tools that can not only aid in designing better products but also allow for the optimization of designs. A significant reduction of the input power of a rotodynamic fire pump, while retaining its primary point of operation, is demonstrated in multi-variant CFD-aided redesign.

Abstract:
Structures and functions of a mosquito’s pump system were investigated experimentally to clarify the mechanistic aspects of this optimized bio-pump. The three-dimensional strucure of the pump that was reconstructed by 1500 slices of the mosquito’s head was obtained using a histopathological method. The mosquito’s pump motion is predictable, and the pump volume can be estimated by the three-dimensional structural observations. The pump volume of the pumps, an oral cavity pump and pharynx pump, were estimated as being 7.92×10−4mm3, 63.3×10−4mm3 respectively. The frequency of the mosquito’s pumps was predicted to be 2.09–16.7 Hz, and was estimated using the pump volume and the volumetric blood flow rate. The motion of the mosquito’s pumps was visualized directly by an x-ray phase contrast imaging method using synchrotron radiation. It was found that the mosquito’s pumps (i.e., the oral cavity pump and the pharynx pump) worked alternately with a 4.23 Hz pump frequency. Moreover, the phase difference of each pump was almost 0.5, suggesting that the mosquito’s pumps worked in opposite phases. In addition, the mosquito’s pumps were found to work as a inline pump, which is suitable for increasing the pressure head of pump.
