Factors to consider for hydraulic pump accessories
-
When the amount of disclosure of certain components in the Hydraulic Vane Pumps accessories is too large, the pressure energy of the hydraulic oil is converted into heat energy. If the capacity of the heat sink is limited or the heat dissipation is poor, the equilibrium temperature of the hydraulic oil will rise, and the oil temperature will be too high in a short time, and the viscosity of the oil will drop. This will further increase the disclosure, resulting in a significant reduction in volumetric efficiency and the efficiency of the entire system. Rubber seals, hoses, etc. age early and lose their functions.
The moving speed of the actuator in the hydraulic pump accessories should meet the regular speed range. The hydraulic pump accessories request that there is no crawling phenomenon at low speed and no hydraulic shock at high speed; the speed is smooth when switching, and the speed change under variable load conditions should be small and many more.
The hydraulic pump accessories must first determine the thrust required by the machine, whether the thrust needs to be maintained for a long time, what speed is required, constant speed or variable speed, the inertia force at start and stop is not large, and when it is required to reduce the impact.
After the hydraulic pump accessories have determined the speed and thrust of the power unit, you can select the power source, including the prime mover and the oil pump. In the workshop, the electric power is sufficient, and the electric motor is preferred. The small flow system on the consumption line can be pneumatic, and the diesel engine can be used in the field activities. According to the working environment of the machine, frequency of use, pressure level of gear pump accessories, flow range, cost limit and other elements, consider which plunger Fixed Vane Pumps to use.
