1, The output flow of the hydraulic pump is insufficient or does not produce oil, which is divided into insufficient suction,excessive leakage, too small inclination of the swashplate, very small displacement of the pump, etc.
2, When the hydraulic pump is overheated, the first case is heat generated by mechanical friction, and the second case is liquid friction heat.
3, The output flow fluctuates. This problem is related to many factors, such as unstable piston movement when impurities enter the variable mechanism, or due to the lack of capacity of the amplifier or component damage.
