Reason and solution of abnormal output pressure of variable displacement piston pump

[Asia Pump Network News] Variable piston pump output pressure is determined by the load, and the input torque is approximately proportional. The output pressure is abnormal There are two kinds of output pressure is too low and the output pressure is too high, then the two causes of failure where? And how to solve? The following is the variable piston pump output pressure on the two causes of failure and solve Method introduction. Variable piston pump output pressure abnormalities causes and solutions (1) the output pressure is too low When the pump in the self-priming state, if the leakage of oil into the pipeline or the system cylinder, one-way valve, the larger the valve Leakage, will not increase the pressure to go up. This requires finding leaks, tightening, and changing seals to increase pressure. Pressure relief valve or adjust the pressure is low, the system pressure also does not increase, the pressure should be re-adjusted or overhaul relief valve. If there is a large amount of leakage due to the deviation between the cylinder of the hydraulic pump and the valve plate, in severe cases, the cylinder may rupture. Then, grind the mating surface or replace the hydraulic pump. (2) the output pressure is too high If the loop load continues to rise, the pump pressure continues to rise, it is normal. If the load is constant and the pump pressure exceeds the pressure required by the load, check the hydraulic components other than the pump, such as the directional valve, pressure valve, transmission, and return line. If the maximum pressure is too high, should adjust the relief valve.
