Abstract:

As we known, the energy efficiency of pump-control system is higher than valve-control system. So, using pump-control system to replace valve-control system has a positive meaning to improve the energy efficiency in hydraulic press machine. In order to research the performance of servo pump used in hydraulic press machines, the present study is conducted. First, a test bench for comparison of pump-control and valve-control system is established. In this test bench, the pump of former valve-control system and the servo pump are settled. These two pumps are switched by solenoid to supply oil for

Abstract:

Poorly designed user interfaces limit the effective use of medical devices, leading to user errors. Hence, before such devices are implemented, it is essential to identify potential usability issues. A common approach to testing usability is a simulation-based test, which allows practitioners to identify usability issues by observing how users interact with the product being tested. Infusion pumps are frequently used in medical settings, and much effort has been made to advance their design and features. To enhance patient safety, smart intravenous (IV) pumps with safety functions (e.g., drug

Abstract There are few studies and reports related to horizontal main pumps for nuclear power plants. The installation of vertical main pumps for small reactors requires the design of special elbows on the pressure vessel. Horizontal main pump, as a new main pump structure, can reduce the diameter of the main pressure vessel and simplify the structure of the pressure vessel. Compared with the vertical main pump, the horizontal main pump needs to control its axial dimension to improve its stiffness, which makes it impossible to set a long straight pipe section at the inlet, which has an impact

A ring pump (RP) is a useful tool for microchannels and automated cell culturing. We have been developing RPs (a full-press ring pump, FRP; and a mid-press ring pump, MRP).

Therefore, first, we evaluated the damage to cells that were sent by a small size FRP (s-FRP) and small size MRPs (s-MRPs; gap = 25 or 50 μm, respectively). “Small size” means that the s-FRP and the s-MRPs are suitable for microchannel-scale appl

Currently, energy needs are increasing greatly, this is influenced by increasing population growth and human activity. The development of simpler renewable energy must be encouraged to meet energy needs, at least to meet the domestic energy needs of households. A hydram pump is a tool that can utilize water flow to produce kinetic energy which is then converted into potential energy to lift water to a certain height. This potential energy can be converted into electrical energy through a generator. A hydram pump is a tool used to raise water from a low place to a higher place automatically wit

Abstract:

Each part of a hydraulic press dissipates a large amount of energy when energy or power is transmitted. Therefore, this study proposes a 3-D vertical arrangement structure for the hydraulic press to reduce their energy dissipation. In the proposed structure, the aboveground and underground spaces are comprehensively utilized, and then the hydraulic equipment are arranged three-dimensionally and set in layers according to the functional requirements. Some equipment is connected directly to minimize the use of valves and pipelines and reduce the transmission distance of hydraulic energy between

Abstract:

The basis of every hydraulic system is based on energy transformations, which are realized through hydraulic working fluid. Hydraulic oils are certainly subject to changes within their structure, meaning the basic characteristics and parameters of hydraulic oil, such as density, viscosity, humidity. The oils that are exploited are exposed to the process of degradation, which largely leads to significantly poorer quality of hydraulic fluid. The paper deals with the influence of changes in the characteristics of the hydraulic fluid on the hydraulic operating parameters of the gear pump installed

Abstract:

The internal flow is very complex in the multiphase pump, especially in the static impeller, where the flow is more disorganized than that in the impeller wheel, and it will cause greater hydraulic losses. In order to investigate deeply the flow rules within the static impeller, all kinds of the flow losses are analyzed quantificationally in the multiphase pump. Based on the standard SST k-ω turbulence model, selected the helical axial flow multiphase pump as the research object, used the three-dimensional modeling software for the three-dimensional modeling of the flow through parts of the mu

Micro/nanopatterns with micro deposition techniques have been used in various applications such as flexible electronic devices, biosensing, and biological tissue engineering. For depositing a small size of droplets that can be controlled, structured and patterned precisely is a very important process for microfabrication. In this study, we developed a low cost and simple system for fabricating micro/nanostructure by a selective micro deposition process using a syringe pump. This method is an additive fabrication method where selective droplet materials are released through a needle of the syri

Abstract:

Analyzes the change of hydraulic pressure and flow rate during the opening/closing and curing processes in the hydraulic system of hydraulic tire curing machine and proposes a new design of the hydraulic station. By using three groups of motors-variable piston pump to work independently, the new hydraulic station can reduce machine downtime. Through using accumulator to keep pressure and delaying switching time of the valve to gradually release pressure, the new hydraulic station solves the problem of the severe impact caused by pressure relief and improve the safety and relia-bility.

Human–robot collaborative disassembly is an approach designed to mitigate the effects of uncertainties associated with the condition of end-of-life products returned for remanufacturing. This flexible semi-autonomous approach can also handle unpredictability in the frequency and numbers of such returns as well as variance in the remanufacturing process. This article focusses on disassembly, which is the first and arguably the most critical step in remanufacturing.

The habit-forming effects of abused drugs depend on the mesocorticolimbic dopamine system innervating the nucleus accumbens (NAcc). To examine whether different NAcc subterritories (core and medial shell) exhibit a differential distribution of neurons showing phasic firing patterns correlated with drug-seeking behavior, rats were trained to self-administer cocaine, and activity of single NAcc neurons was recorded. In the presence of a discriminative-stimulus (SD) tone, a single lever press produced an intravenous infusion of cocaine (0.35 mg/kg), terminated the tone, and started an intertone i

Abstract:

A hydrophore tank or water pressure tank is a tank that stores water temporarily and then separates water and air through a membrane so that the air in it is compressed. The water in the tank is flowed into a distribution building. The pump works automatically, regulated by a pressure detector, which closes/opens the electric motor's switch driving pump. The pump stops working when the pressure in the tank reaches a specified minimum. In this system, the compressed air will press water into the distribution system. After repeatedly expanding and compressing over time, it will decrease because

The theoretical analysis of the operation of a high-speed hydraulic reciprocating drive for a cyclic press made using a pump-accumulator power source containing one hydraulic accumulator showed that increasing its speed is technically possible, but not economically justified.

In hydraulic systems, energy dissipation can be significant. The pressure losses that can occur in the hydraulic circuit, which are influenced by the adopted drive architecture, result in power consumption that is often significantly higher than that required by the mechanical system.

The analysis is applied to a variable speed and force hydraulic blanking press, a fairly common industrial system, e.g., in the manufacture of semi-finished brass products. Standard, r
