Common troubleshooting tips for importing gear pumps from Desmi ROTAN

1. Add some oil to the connection or seal. If the noise is reduced, tighten the joint or replace

 the seal. The return oil pipe should be below the oil level and have a certain distance from

 the oil suction pipe.

2. Correct the direction of the motor.

3. Clear the pipeline, clean the oil filter to remove the blockage, and replace the new oil.

4. Repair and replace related parts.

5. Tighten the screws at each connection to avoid leakage and prevent air from mixing.

6. The oil should be selected according to the temperature rise.

7. Remove dirt to make the oil suction pipe unobstructed, or use an oil filter with appropriate capacity.

8 Adjust the concentricity and eliminate scratches.

9. Replace the gear or grind and repair.

10. Check the skeleton oil seal and replace it if it is damaged to avoid air inhalation.
