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
