Fault symptoms and possible causes

Unable to start: Possible reasons include power failure, motor damage, control switch issues, etc.

Poor suction effect: Possible reasons include worn rotating blades, poor sealing, and blocked air passages.

Excessive noise: Possible causes include bearing damage, loose discs, and casing issues.

Water ingress: Possible causes include condenser leakage, aging of seals, and pipeline connection issues.

Troubleshooting methods

Check the power supply and control switch: Ensure that the power supply is normal, check the switch for damage or poor contact, and replace or repair it if necessary.

Check the rotating blades and seals: Check if the rotating blades are worn and replace them if necessary. At the same time, check the integrity of the sealing components to ensure good sealing, and replace them if necessary.

Clean the air circuit: Check if there are any blockages in the air circuit, clean the pipelines and filters, and ensure that they are unobstructed.

Check bearings and rotating components: Check whether the bearings are damaged. If there is any abnormal noise or looseness, promptly handle or replace them.

Check the condenser and pipelines: Check for water leakage in the condenser and address the issue of water leakage. Check if the pipeline connection is secure, and if there is looseness or air leakage, adjust or replace the seal.

Maintenance and preventive measures

Regular cleaning and maintenance: Regularly clean the rotating blades, condenser, and air circuit to ensure no dust and dirt accumulation and maintain good working condition.

Adjust the usage environment: Ensure that the usage environment of the rotary vane vacuum pump is dry and clean, and avoid excessive temperature and humidity.

Regular inspection and replacement of components: Regularly inspect the wear of rotating blades, bearings, seals, and other components, and replace damaged or aged components in a timely manner to ensure the normal operation of the equipment.
