How to safely maintain the plate and frame oil filter?

Proper safety maintenance of the plate and frame oil purifier is the key to ensure long-term stable operation of the equipment and avoid accidents. The following are detailed maintenance steps and precautions:

I. Daily maintenance

1. Check the oil system

- Check whether the oil pipes, joints and valves are leaking or loose, and tighten or ｒｅｐｌａｃｅ damaged parts in time.

- Ensure that the oil circuit is unobstructed to avoid blockage.

2. Clean the filter plate and filter cloth

- After each use, clean the oil residue and impurities on the filter plate and filter cloth.

- Check whether the filter cloth is damaged and ｒｅｐｌａｃｅ it in time to avoid affecting the filtering effect.

3. Check the pressure gauge

- Confirm whether the pressure gauge is working properly and ensure that the pressure is within the allowable range of the equipment (usually 0.4-0.6MPa).

- If the pressure is abnormal, stop the machine immediately for inspection.

4. Check the oil pump

- Check whether the oil pump is running normally and whether there is any abnormal sound or vibration.

- Clean the oil pump inlet filter regularly to prevent blockage.

5. Check the electrical system. - Check whether the power cord, switch and control system are normal to avoid electrical failure. - Clean the dust in the electrical cabinet regularly to prevent short circuit. 2. Regular maintenance 1. ｒｅｐｌａｃｅ the filter cloth and seals - According to the frequency of use, regularly ｒｅｐｌａｃｅ the filter cloth and seals (such as O-rings) to ensure sealing. - Pay attention to cleaning the installation position when replacing to avoid impurities. 2. Clean the filter plate - Remove the filter plate regularly and clean it thoroughly with detergent to avoid oil residue accumulation. - Check whether the filter plate has cracks or deformation and ｒｅｐｌａｃｅ it in time. 3. Lubricate moving parts - Regularly add lubricating oil to moving parts such as screw rods and guide rails to ensure smooth operation. - Check whether the screw rod is worn and ｒｅｐｌａｃｅ it if necessary. 4. Check the hydraulic system - Check whether the hydraulic oil is sufficient and clean, and ｒｅｐｌａｃｅ the hydraulic oil if necessary. - Check the hydraulic cylinder and oil pipe for leaks and repair them in time.

5. Calibrate the pressure gauge and safety valve

- Calibrate the pressure gauge regularly to ensure accurate readings.

- Check whether the safety valve is working properly to ensure that it can release pressure in time when overpressure occurs.

III. Precautions for safe operation

1. Check before operation

- Check whether all parts of the equipment are normal before starting the machine to ensure that there is no looseness, leakage or damage.

- Confirm that the filter cloth is installed correctly and the filter plates are arranged neatly.

2. Control pressure

- During operation, pay close attention to the pressure gauge to avoid overpressure operation.

- If the pressure rises abnormally, stop the machine immediately for inspection.

3. Prevent burns

- During the operation of the equipment, the oil temperature may be high, so avoid direct contact with high-temperature parts.

- Wait for the equipment to cool down after stopping before maintenance.

4. Prevent electrical accidents

- Avoid touching electrical equipment with wet hands during operation.

- Check the grounding wire regularly to ensure that the equipment is well grounded.

5. Prevent mechanical injuries

- When the equipment is running, it is forbidden to put your hands or other objects between the moving parts (such as filter plates, screws).

- Be sure to cut off the power supply during maintenance and hang warning signs.

Fourth, common faults and treatments

1. Poor oil filtering effect

- Cause: The filter cloth is damaged or blocked, and the oil is too dirty.

- Treatment: ｒｅｐｌａｃｅ the filter cloth and clean the oil circuit.

2. Abnormal pressure

- Cause: The filter cloth is blocked, the oil circuit is not smooth, or the oil pump is faulty.

- Treatment: Clean the filter cloth and the oil circuit, and check the oil pump.

3. Oil leakage

- Cause: The seal is aging or the filter plate is not pressed tightly.

- Treatment: ｒｅｐｌａｃｅ the seal and re-tighten the filter plate.

4. Equipment vibration or abnormal sound

- Cause: The oil pump or motor is faulty, and the filter plate is not aligned.

- Treatment: Check the oil pump and motor, and rearrange the filter plate.

V. Maintenance Records

- After each maintenance, record the maintenance content, replacement parts and problems found to facilitate follow-up tracking and management.

- Regularly summarize the equipment operation status and optimize the maintenance plan.

Through the above measures, the safe operation of the plate and frame oil purifier can be effectively guaranteed, the equipment life can be extended, and the failure rate and safety risks can be reduced.
