Solutions for lack of oil displacement of axial piston pump

点击:129 发布时间:2020-05-06

Reasons and solutions for lack of oil displacement of axial piston pump:    1) The obstruction or resistance of the oil suction pipe and the oil filter is too large: it should be cleaned in real time to remove the blockage.
    2) The diameter of the oil suction pipe is too small: properly increase the diameter of the pipe to make the oil suction smooth.
    3) The oil level of the hydraulic oil tank is too low: the amount of oil should be checked and the oil should be added properly.
    4) The pump body is not filled with oil spill, and some atmosphere: the pump should be filled with oil and exhausted.
    5) The seal is not strict, and there is an atmosphere: tighten the relevant joints.

    6) Wear between the plunger and the cylinder hole or the oil distribution plate and the cylinder body: the contact surface should be changed for good contact.
    7) The leakage in the hydraulic pump is severe, and the volumetric efficiency is low: the hydraulic pump is properly repaired.
    8) The return stroke of the plunger is inadequate or cannot be returned, causing a seal between the cylinder and the oil distribution plate: the core spring is broken, the core spring should be checked and replaced.
    9) If the variable mechanism fails, the mission request cannot be reached: the adjustment error should be checked and corrected.
    10) Improper oil temperature or suction by hydraulic pump, resulting in internal leakage or hard oil absorption: according to the actual environment of temperature rise, select the appropriate oil and fasten the adjacent place that can leak.
    11) The motor speed is insufficient: find the reason and stop adjusting.
    12) Excessive viscosity of oil: change the oil with proper viscosity in real time.
