摘要: In this paper, the flowrate formula of the annular clearance between piston and cylinder in hydraulic piston pump is revised because the seal length of piston becomes different. The revised coefficient makes things convenient for volumetric efficiency calculation in hydraulic piston pump....

Install a flow meter in the case drain line and check the flow rate. Most variable displacement pumps bypass one to three percent of the maximum pump volume through the case drain line. If the flow rate reaches 10 percent, the pump should be changed. Permanently installing a flow meter in ...
The influence of liquid cargo density on discharge rate of hydraulic submerged cargo pumps on modern product and chemical tankers Main parts of hydraulic structure of a/m system and cargo pump torque controller functions are described. The formula is given for the dependence of ... A Banaszek 被...
The main conclusions are as follows: the fluid multiplier fish pump body produced a flow rate 2.8–3.5 times higher than the water injection port in the jet gap area, and under the influence of the high-flow-rate area, the low-pressure area generated at the fish inlet amplified the flow ...
液压相关概念(Hydraulic concepts) Does the hydraulic pump and the pump pressure test what difference The hydraulic pump is to provide power to the mechanical energy into hydraulic pressure test pump, and the size of the pressure test, so as to adjust the flow. What is hydraulic impact? What ...
In FIG. 5, a maximum delivery oil amount (maximum delivery flow rate) QU that results when the pump pressure Pp is low, increases and decreases depending on the first and second line pressures Pr1, Pr2, which are changed in accordance with the stroke shifts of the control levers 19, 20....

In the modeling of a conventional pump control system, the oil replenishment link is typically disregarded, which results in a certain deviation in the analysis results. Therefore, the relationship between the flow rate and pressure in this study was analyzed, as shown in Figure 5. Figure 5 Dia...
