Reasons for insufficient pressure of hydraulic oil vacuum filter

Insufficient pressure of the hydraulic oil vacuum filter will affect the filtering effect and the normal operation of the equipment. The following are possible reasons and solutions:

1. Check the oil system

- Cause: The oil circuit is blocked, the valve is not fully opened, or the pipeline is leaking.

- Solution:

- Check whether the oil circuit is blocked and clean the blocked parts.

- Make sure all valves are fully open.

- Check whether the pipeline connection is leaking, tighten or ｒｅｐｌａｃｅ the seals.

2. Check the filter element status

- Cause: The filter element is blocked or seriously contaminated, resulting in poor oil flow.

- Solution:

- Check whether the filter element is blocked and ｒｅｐｌａｃｅ or clean the filter element in time.

- Maintain the filter element regularly to avoid excessive contamination.

3. Check the vacuum pump

- Cause: The vacuum pump oil is insufficient, the oil quality is deteriorating, or foreign matter enters the pump.

- Solution:

- Check the vacuum pump oil level and add or ｒｅｐｌａｃｅ new oil.

- Clean the inside of the vacuum pump and remove foreign matter.

- Check whether the vacuum pump blades are worn and ｒｅｐｌａｃｅ them if necessary.

4. Check the oil status

- Cause: The oil viscosity is too high or contains a lot of impurities, which increases the operating load of the equipment.

- Solution:

- Check the oil viscosity and heat it to reduce the viscosity if necessary.

- Filter the oil to remove impurities.

5. Check the motor and pump

- Cause: Motor or pump failure, resulting in insufficient pressure.

- Solution:

- Check the operating status of the motor and pump, and repair or ｒｅｐｌａｃｅ them if necessary.

- Check the inlet and outlet pressures of the pump to ensure that the pump works normally.

6. Check the vacuum degree

- Cause: Insufficient vacuum degree affects the filtering effect.

- Solution:

- Check whether the vacuum system is leaking and tighten the connection parts.

- Check the performance of the vacuum pump and repair or ｒｅｐｌａｃｅ it if necessary.

7. Check the heating system

- Cause: Failure of the heating system causes the oil temperature to be too low and the viscosity to increase.

- Solution:

- Check whether the heating system is working properly, and repair or ｒｅｐｌａｃｅ the heating element if necessary.

- Make sure the oil temperature is within the appropriate range (usually 40-60°C).

8. Check the equipment parameter settings

- Cause: Improper equipment parameter settings affect pressure.

- Solution:

- Check the equipment parameter settings to ensure that parameters such as flow and pressure meet the requirements.

- Adjust parameters according to the oil status and equipment performance.

9. Check the equipment maintenance records

- Cause: The equipment has not been maintained for a long time, resulting in performance degradation.

- Solution:

- Maintain the equipment regularly and ｒｅｐｌａｃｅ wearing parts.

- Record maintenance status to discover and solve problems in time.

10. Check environmental factors

- Cause: The ambient temperature is too low or too high, affecting the performance of the equipment.

- Solution:

- Move the equipment to a suitable environment to avoid extreme temperatures.

- Install insulation or heat dissipation devices around the equipment.

Summary

Low pressure in the hydraulic oil vacuum filter may be caused by oil circuit blockage, filter element contamination, vacuum pump failure, poor oil condition, motor or pump failure, insufficient vacuum, heating system failure, improper parameter setting, insufficient equipment maintenance or environmental factors. By gradually troubleshooting and taking appropriate measures, the problem can be effectively solved and the normal operation of the equipment can be restored. If the problem is complicated, it is recommended to contact professional technicians for maintenance.
