Abstract:

The paper describes studies of the stress-strain state of power hydraulic cylinders elements. Geometric dimensions of casing and properties of materials are chosen as varied parameters. The controlled values are the levels of stresses and displacements. The criteria are weight, strength and rigidity. These characteristics determine the technical characteristics of power hydraulic cylinders. Dependences of criterion characteristics on varied parameters are established. On this basis, recommendations for substantiation of design and technological solutions of power hydraulic cylinders elements a

Abstract:

The aeroacoustic sound generated in a flow past two cylinders, one of which is oscillating and the other is fixed, is studied by direct numerical simulation. This problem involves key ingredients of the aeroacoustic noise generated from wind turbines, helicopters, axial flow fans and other turbomachinery: flow, a moving body and a fixed body. The corrected volume penalization method is successfully applied to resolve the sound pressure of aeroacoustic waves as a solution of the compressible Navier–Stokes equations. The sound pressure was shown to be in good agreement with the prediction by the

Abstract A mechanical model of the synchronous hydraulic system of the propulsion mechanism is established by taking the power head propulsion system of an engineering hydraulic drilling rig as the research subject. A master-slave regulation method based on the PID control strategy is proposed for the displacement deviation of two synchronous cylinders under the disturbance of external force. The method controls the synchronous accuracy of the two propulsion cylinders.

Abstract:

One of the disadvantages of spark ignition engines, whose power is regulated by throttling, is the increased fuel consumption at low loads and when the engine is idle. The combined method of engine power regulation by switching off the cylinder group and throttling working cylinders is one of the effective ways to improve fuel economy in the above-mentioned modes. This article presents the research results of the combined method of engine power regulation which can be realized by minor structural changes in operating conditions. The method implies the following: at low loads and at idle speed

Abstract:

The wave energy converter (WEC) system, which extracts electricity through the relative heave motion of two concentric cylinders, comprises an inner cylinder and a torus-type outer cylinder sliding along the inner cylinder. To maximize the relative heave motion between two cylinders, the natural frequencies of the two cylinders must be precisely tuned to resonate and be situated on each side of the peak frequency of the wave spectrum. However, the demerit of this strategy is that it demands a deep draft of each cylinder for tuning, and a large-scale PTO damping device is necessary for mechanic

The piston/cylinder pair is the key lubricating interface of axial piston pumps. It suffers from excessive wear due to the huge lateral force, especially under high output pressure. In order to achieve predictive maintenance, it is significant to detect the performance degradation of the piston/cylinder pair. In this paper, a method to predict the wear of the piston/cylinder pair is proposed. The wear regions and corresponding wear depths under different conditions are investigated.

This paper presents a conceptual study aiming to improve the compactness of electro-hydraulic compact drives (ECD ). In most current ECD architectures, gas accumulators are used as volume compensators for the flow imbalance emerging whenever asymmetric single rod cylinders are used. To stay within a required reservoir pressure range typically from two to four bar, a large gas volume is required, compromising system compactness. Combining conventional ECD architectures with a bootstrap reservoir offers a greater degree of freedom in system design, which enables downsizing or avoidance of the ga

Abstract:

Considerable effort has been put forth to develop an automated method for balancing the power cylinders of reciprocating integral engines used in the natural gas industry. The benefits to power cylinder balance include reducted emissions and improved cylinder component mechanical integrity (which should lead to reductions in repair costs). The current approach to automate engine balancing uses pressure transducers to measure cylinder pressure, then integrate the signals into the engine fuel /timing management controller to achieve engine balance. Each power cylinder must be instrumented, which

Abstract:

Investigates potential and procedures for selective deactivation of one or more power cylinders in two-cycle engines under reduced load to effect fuel savings while avoiding possible engine derangement. The objectives were to identify any major problems with cylinder deactivation, to quantify likely benefits, to determine potential increases in load or stress, and to generate guidelines from the project results. This study showed that economic benefits are possible with the careful use of cylinder deactivation; however, several operational problems were encountered, such as spark plug fouling,

Full text

Abstract:

A timed lube oil injection system was developed for a field engine to improve power cylinder lubrication. The injection system used advanced prototype electronic injectors. The system was installed on a Cooper GMVA-10 located in West Virginia. A total of four cylinders were included in the study, two for the timed system and two for the baseline mechanical system. Cylinder wall lubrication, cylinder wear, piston wear, and ring wear tests were planned for various engine run times. The prototype timed lube oil system operated essentially until the prototype injector end-of-life was reached at ab

Full text

Abstract:

This project is driven by concerns over excessive cylinder lubrication in large bore two-stroke natural gas engines (LBNGE). Excessive cylinder lubrication can lead to: - Increased operating costs due to high lubricating oil consumption. - Poisoning of catalytic converters. - Increased pollutant emissions. Development of an electronically-controlled, power-cylinder lubricator (ECPCL) is a likely solution that could decrease excessive cylinder lubrication. This lubricator would optimize cylinder lubrication by controlling both the injection rate and injection timing, relative to piston position

Abstract:

A retrofit lube oil injection system is designed with the capability of injecting oil through two lube ports on each cylinder at any time during the engine cycle. The system is installed and tested on a Cooper-Bessemer GMV4 engine. Variations in number of skip cycles, average lube rate, and injection timing are evaluated. Lube oil carry-over is quantified using a dilution tunnel and a standard particulate matter gravimetric measurement technique. Cylinder wall lubrication is quantified using a custom designed fixture that is inserted into the fuel valve port between data points when the engine

Abstract:

The American Association of State Highway and Transportation Officials R 100 standard provides instructions for making and curing concrete test specimens in the field. However, further research is needed to compare the strength of the field-cured specimen with the strength of the actual in-place concrete item. The purpose of this combined laboratory and field study was to evaluate field-curing methods of concrete specimens for estimating the early opening strength of an in-place concrete item. The researchers used one Illinois Department of Transportation class PV mix to cast cylinders, beams,

Abstract:

NOX emissions regulations below 1.0 g/bhp-hr are being implemented in some parts of the country (e.g. Houston). Increasing engine efficiency is one way to increase gas transport. However, a dilemma that often occurs is techniques that reduce NOX emissions often simultaneously decrease engine efficiency. An alternative approach to increasing gas transport is to increase the power output, or brake mean effective pressure (BMEP), of the large bore natural gas engines presently in service. The onset of knock typically limits the maximum power output of spark ignition engines; water injection can e
