Mechanical diaphragm pump It is important to replace the diaphragm regularly

The diaphragm in the diaphragm pump of mechanical equipment is a perishable component and needs to be replaced on time. If the customer does not pay attention to the replacement in the application, it will cause a safety accident in the case of damage, so Depamu friendly tips to replace the diaphragm on time is very important.

In general, the diaphragm should be replaced after 8,000 hours of operation, otherwise it will lead to fatigue damage, cracking, etc., which will endanger the service life of the facility, lead to environmental pollution of the grease, drive the piston rod cylinder, and lead to damage to critical facilities. 

When the diaphragm pump is operating, the camera and hydraulic transmission system should be regularly maintained according to the appropriate process to avoid common failures of the oil drain camera, blockage of the supplied oil and oil pipeline or common failures of the pipeline gate valve, heart rate disorders caused by battery charging and charging and discharging oil, and contributing to water accumulation. Variable working pressure; Strictly implement the regulations for the operation of diaphragm pumps and working pressure modules, and strictly prohibit overweight operation; Check the uneven ground stress caused by the change of working pressure at the diaphragm pump inlet and outlet of the diaphragm pump check valve. The ground stress will cause the diaphragm to crack and must be replaced immediately.

There are many types of diaphragm pumps, but be sure to check and replace spare parts regularly.

1. The pump body is made of pig iron, which is easy to crack because of mechanical equipment force or internal stress. It needs maintenance. If the damage is more serious, replace it immediately. Some safeguards can be applied to the pump body to reduce damage.

2. The pump shaft is generally made of high carbon steel, which is very easy to damage after long-term application. It is very likely to produce cracks, bending, motor shaft wear, external thread damage, etc., and may produce a rupture safety accident, should be replaced immediately.

3. Impeller is the key component of the pump. There will be cracks in the impeller. Due to cavitation, the surface layer is perforated or broken. Long-term etching will make the tool head soft or partially worn, and even broken. If you do, replace it with a new one.

4. The mouth ring is also called the leakage or wear reduction ring, which is easier to wear. Wear and tear can be easily repaired and cannot be replaced immediately. When replacing a new leakage reduction ring, its inner diameter should be equipped according to the diameter of the impeller channel.

5. After long-term placement, the filling material will be hard and lose ductility, which will cause the centrifugal pump to leak gas and water. In general, new packaging should be used.

Mechanical equipment diaphragm pumps have many parts and components, and the level of damage is higher. With regular maintenance and maintenance, the service life can be increased, which is also of great benefit to the pump.
