Fault Phenomenon And Solution Of Precision Hydraulic Cutting Machine 2

- Sep 03, 2019-

9. Insufficient work pressure


(1) The layer is too thick: reduce the layer


(2) The die setting stroke is adjusted too low: adjust to the appropriate position


(3) Filter plugging: Cleaning or replacing the filter


(4) Oil pump damage: Replace the oil pump


10. Oil leakage


(1) Cylinder oil seal aging: replace the oil seal


(2) Loose high pressure oil pipe joint: tighten the joint


11. Motor oil pump noise


(1) Oil pump rotating rubber particle wear: replacing rubber particles


(2) Filter plugging: cleaning filter


(3) Hydraulic oil loss: add hydraulic oil


(4) Oil pump bearing damage: replacement of bearings


(5) Oil pump shaft end oil seal aging: replace oil seal


(6) Motor bearing damage: replacement of bearings


12. When the speed is slowed down or rising, the crash cannot rise or fall.


(1) Aging of the cylinder seal: replacement of the seal


(2) Solenoid valve spool wear is serious: replace the solenoid valve


(3) Pressure oil viscosity reduction: replacement of pressure oil


(4) Poor board contact: check the line


(5) The main road cannot be switched: check the line


(6) Solenoid valve stuck: clear valve body
