Four-column Cutting Machine Failure Phenomenon III


10. Oil leakage


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


(2). High pressure tubing joint loose: tighten the joint


11. Motor oil pump noise


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


(2). Filter blockage: 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: replace the bearing


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


(1). Cylinder seal aging: replace the seal


(2). Solenoid valve spool wear is severe: 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
