Common faults and simple handling methods of industrial dry cleaning machines

1、 Press the button to indicate that the light does not light up or the computer does not display when starting the machine. The machine does not work
1. Whether the main switch is powered on and whether the main switch is connected
Push on the main brake and use a multimeter to measure whether there is three-phase electricity
2. The fuse in the electrical box is burnt out
Disconnect the power supply and use a multimeter to measure whether the fuse in the electrical box is burnt out. If the fuse is replaced and burnt out again, ask a professional to inspect it
3. Key switch failure
Replace the key switch
4. The computer board fuse is burnt out
If the replacement fuse burns out again, please have it checked by a professional person
2、 Poor circulation of dry cleaning oil
1. The solvent pump is blocked
Cleaning solvent pump
2. Pipeline blockage
Clean the pipeline
3. Pneumatic valve failure
Replace or repair the pneumatic valve
4. The suction pipe is blocked due to the dirty bottom box
Clean the bottom box and dredge the suction pipe
5. Nylon filter too dirty
Cleaning the filter
6. Motor reverse
Swapping wires
3、 Clothes won't dry
1. Too much liquid in clothes
Properly extend the drying time
2. Poor cooling effect or low tap water pressure
Clean the condenser and increase the cooling water pressure
3. Recovery pipeline blocked
Clean the recovery pipeline
4. Insufficient heating temperature, unable to rise
Increase heating, temperature, adjust temperature controller
5. The air duct is blocked, and the wind power of the fan is insufficient
Clean the air duct, check the machine status, and extend the drying time
4、 The drying machine does not work, and the noise is loud when drying
1. Metal filter drain valve not open
Open the discharge valve (due to the interlock between the discharge valve and the drying)
2. Thermal relay not reset, AC contactor coil burnt out
Repair or replace the original electrical components
3. Drying button failure
Replace the key
4. Computer has no output
Repair the computer
5. Main bearing worn or damaged
Replace the main bearing and pay attention to regular oil filling
5、 Dry cleaning oil cannot be discharged
1. Metal filter pipe blocked
Clean the pipeline
2. Blockage and malfunction of metal filter discharge valve
Clean the drain valve, repair and replace the drain valve
3. Malfunction of the solenoid pilot valve that controls the drain valve
Repair or replace the electromagnetic pilot valve
4. Press the key switch or the computer board has no output
Replace the switch or repair the computer board
6、 Abnormal temperature display
1. Temperature probe damaged
Replace the temperature probe
2. The temperature probe plug is loose
Reinsert the temperature control head into the press
3. Computer internal damage
Repair or replace the computer board
