Common failure treatment of piston pump
x09x09 (3) no connecting key on pump shaft or motor shaft1) break2) missing x091) replace key2) patch keyx09x09 (4) pump internal slide vice stuck1) the clearance is too small2) parts accuracy is poor, assembly quality is poor, gear and shaft coaxial deviation is too large; plunger head clamping; blade perpendicularity difference; rotor pendulum difference is too big, rotor slot has wound or blade has scar, force after fracture and stuck
1) overflow valve regulation is too high, overload after the pump2) the overflow valve spool is blocked, the central hole of the valve core is blocked or the overflow valve is blocked by a damping hole, and the overflow is not overflow3) pump outlet one-way valve installed or spool blocked and stuffy pump4) motor fault x091) adjust the relief valve pressure value2) repair valve boring3) overhaul check valve4) overhaul or replace the motor
Table 15 common troubles and treatment of hydraulic pumpsFault phenomenon, x09 cause analysis, x09 elimination method(1) the pump does not carry oil; the x091. pump does not turn x09 (1); the motor shaft does not rotate1) missed connection power supply2) electrical wiring and component failure, x09 check electrical and troubleshootx09x09 (2) motor heating trip
