Hydraulic cutting machine common faults and solutions

Hydraulic cutting machine belongs to the machine category. In our work, the machine will inevitably cause some failures. Here we will analyze some common faults of the cutting machine during use. Usually you can solve it yourself.

Electrical parts:

1. After the hydraulic cutting machine turns on, the indicator light is off and the motor cannot start. Failure analysis: 1, transformer insurance burned 2, damage to the total gate switch Remedy: 1, replace the fuse 2, replace the main switch

Second, after the start of hydraulic cutting machine indicator light is not bright but the motor can start. Fault Analysis: Indicate Lamp Burnout Remedy: Replace Indicator Lamp

3. The indicator light is on after the hydraulic cutting machine is turned on. The motor cannot start. Failure analysis: 1, the motor overheating switch action 2, the main control contactor defective or burned 3, the motor burned. Remedy: 1, reset the thermal switch 2, replace the contactor 3, replace the motor

Hydraulic section:

First, the pressure of the hydraulic cutting machine is insufficient. Failure analysis: 1, cutting material layer is too thick 2, the die set stroke is adjusted too low 3, filter plugging 4, the pump is damaged. Remedy: 1, reduce the material layer 2, adjust to the appropriate position 3, clean or replace the filter 4, replace the oil pump

Second, the use of hydraulic cutting machine during the occurrence of oil leakage Failure Analysis: 1, oil tank oil seal aging 2, high pressure tubing joints Excluded methods: 1, replace the oil seal 2, tighten the joint

Third, the hydraulic cutting machine work, the motor oil pump noise failure analysis: 1, pump rotation rubber wear 2, filter plug 3, hydraulic oil loss 4, pump bearing damage 5, oil pump shaft seal aging 6, motor bearing damage excluded Method: 1, replace the rubber particles 2, clean the filter 3, add hydraulic oil 4, replace the bearing 5, replace the oil seal 6, replace the bearing

4. After one or two years of use, the hydraulic cutting machine will occasionally experience a slowdown or increase in speed. The machine will not rise or fall. Failure analysis: 1. The aging of the cylinder seal 2. The valve core of the solenoid valve is seriously worn 3. The viscosity of the pressure oil is reduced. 4, poor contact of the main relay 5, solenoid valve stuck exclusion method: 1, replace the seal ring 2, replace the solenoid valve 3, replace the pressure oil 4, check the line 5, clear the valve body
