Fault phenomenon of precision four column hydraulic cutting machine

1. The indicator light is on: the whole machine has no power

2. Transformer fuse burned: replace the fuse

3. Brake switch on: turn on the power brake switch

4. If the indicator light is on, the motor can be started: the indicator bulb is burnt out replaced

5. If the indicator light is on, the motor cannot be started

(1) . motor protection switch trip switch: turn on the motor protection switch

(2) . the main control contactor is poor burned: replace the contactor

(3) . motor burned: replace motor

6. If the indicator light is on, the motor can be started, but it can work

(1) Turn the setting switch of the tool mould to the horizontal position lock the oil circuit: turn the high setting switch of the tool mould to the firm straight direction

(2) . wrong direction of motor: replace two phase lines of motor

(3) . poor contact of working switch, wire end falling off: check that the line is connected properly

(4) . solenoid valve coil burned: replace the coil the whole solenoid valve

(5) . the solenoid valve core is stuck: clean the valve core

(6) . the stroke adjustment handle is loose: reset the tool mold

7. Can work reset: the circuit board in the electric box is burnt out replaced

8. It can work but cannot be reset: the circuit board in the electric box is burnt out replaced

9. Insufficient working pressure

(1) . the cutting layer is too thick: reduce the material layer

(2) . the setting stroke of tool mould is adjusted too low: adjust to the proper position

(3) . filter screen clogging: clean replace the filter

(4) . oil pump damaged: replace oil pump

10. Oil leakage

(1) . oil seal aging: replace oil seal

(2) . loose high pressure oil pipe joint: tighten the joint

11. The motor oil pump makes noise

(1) . oil pump rotating rubber particles wear: replace rubber particles

(2) . filter clogging: clean the filter screen

(3) . hydraulic oil loss: add enough hydraulic oil

(4) . oil pump bearing damaged: replace bearing

(5) Aging of oil seal at oil pump shaft end: replace oil seal

(6) . motor bearing damaged: replace bearing

12. When the speed slows down rises, the aircraft crashes cannot rise fall

(1) . cylinder seal ring aging: replace the seal ring

(2) Serious wear of solenoid valve core: replace solenoid valve

(3) . the viscosity of pressure oil decreases: change the pressure oil

(4) . poor contact of the board: check the circuit

(5) . the main circuit cannot be switched: check the line

(6) . the solenoid valve is stuck: clean the valve body
