There are several reasons why an air diaphragm pump may not work:
Air source problem: The air source is not pure, contains impurities or moisture, which may cause the air operated diaphragm pump to not work properly. It is recommended to install an air filter to ensure the purity of the air supply.
Housing Problems: Damaged or deformed housings may cause the pump to not function properly. Check the integrity of the housing to ensure it is not bent, deformed, or broken.
Lubrication Problems: Insufficient lubrication or improper use of lubricating oil can cause the pump's components to jam or not function properly. It is advisable to use a light and frost-resistant lubricant, and to check and change the lubricant regularly.
Diaphragm Problems: Broken or aging diaphragms can affect the normal operation of the pump and even lead to media leakage. Regularly check the integrity of the diaphragm and replace it as needed.
Supply pressure problems: Too low supply pressure or insufficient air volume may cause the pump to not work properly. Adjust the air pressure and flow rate to meet the standard requirements.
Solutions to these issues include:
Install an air filter to keep the air supply pure.
Regularly inspect and maintain the integrity of the housing.
Use appropriate lubricating oil and change it regularly.
Regularly inspect and replace damaged or aged diaphragms.
Adjust the supply pressure and flow rate to meet the pump's operating requirements.
Through the above steps, the problem of air diaphragm pump not working can be effectively diagnosed and solved. If the problem persists, it is advisable to contact a professional technician for repair to avoid further damage to the pump.
