Leakage of the circulating water vacuum pump is one of the common problems that may affect its normal operation and performance. The following are some common problems with circulating water vacuum pumps, including water leakage and other possible faults and solutions:

1. Water leakage problem:

Check the water pipe connection: Check if the water pipe connection is tight and there is no looseness or leakage. Ensure that the water pipes are not damaged or blocked.

Check the seals: Check the seals of the water ring vacuum pump, such as O-rings and gaskets. If aging or damage is found to the sealing element, replace it in a timely manner.

Clean the sink and water ring: Regularly clean the sink and water ring to ensure that there is no accumulation of impurities and dirt.

Check the status of the water pump: observe if there is any leakage from the water pump. If water leakage is found, it may be necessary to inspect and replace the relevant components.

2. Noise and vibration issues:

Check the installation of the water pump: Ensure that the circulating water vacuum pump is correctly installed on a stable surface and tighten the screws. Loose installation may cause noise and vibration.

Inspect the impeller and bearings: Check for damage or wear to the impeller and bearings. If necessary, replace the impeller or bearing in a timely manner.

Clean the air inlet and outlet: Regularly clean the air inlet and outlet to ensure smooth flow.

3. Reduced pump efficiency:

Check the water inlet volume of the water pump: Ensure sufficient water supply and adjust the water inlet volume of the water pump to achieve good working condition.

Check the filter screen and filter: Clean or replace the filter screen and filter to prevent blockage and impurities from entering the water pump.

4. Temperature rise:

Check the cooling system: Ensure that the cooling system is working properly and that the cooling water temperature and flow rate meet the requirements. Clean the cooling system to prevent blockage and accumulation.

5. Other faults:

Check the power and wire connections: Ensure that the power cord of the circulating water vacuum pump is firmly connected and the socket is working properly. Check if the power switch is turned on to ensure normal power supply.

Check control parameters: Check the control parameters of the circulating water vacuum pump, such as temperature, pressure, speed, etc. Ensure that the parameter settings are correct and adjust as needed.

If the above methods cannot solve the problem, it is recommended to contact the manufacturer or professional maintenance personnel for further diagnosis. Timely troubleshooting and maintenance will help restore the normal operation of the circulating water vacuum pump.
