The diaphragm in the mechanical diaphragm pump is a perishable component and should be replaced on time. If the customer does not pay attention to the replacement in the application, it will lead to a security accident in the phenomenon of damage.

Under normal conditions, 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 equipment, lead to environmental pollution of the grease, drive the piston rod cylinder, and lead to damage to key mechanical equipment.

When the diaphragm pump is operating, the camera and hydraulic transmission system should be regularly maintained according to the appropriate process to prevent common failures of the oil drain camera, blockage of the supplied oil and oil pipeline or common failures of the pipeline gate valve, arrhythmia caused by battery charging and charging and discharging oil, and 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 for uneven ground stress caused by fluctuation of working pressure at the diaphragm pump inlet and outlet of the diaphragm pump check valve. This ground stress can cause the diaphragm to crack and must be replaced immediately.

There are many types of mechanical diaphragm pumps, but be sure to check replacement parts regularly.

1. The pump body is made of pig iron and is very easy to crack due to mechanical force or internal stress. Need 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 carbon steel, which is very easy to be damaged after application. It is very likely to produce cracks, bending, motor shaft damage, external thread damage, etc., and it is also very likely to crack safety accidents, should be replaced immediately.

3. Centrifugal impeller is a vital part of the pump. It is very possible to develop cracks in the centrifugal impeller. Due to cavitation, the surface layer is transformed into holes or broken holes. Etching will make the tool head soft or partially damaged, or even broken. If found, replace with a new one.

4.口环也称之为减漏或减磨环，更易于损坏。损坏可以取得修补，并且没法立即替换。替换新的泄露减少环时，其內径应根据离心叶轮入口处的直径进行配备。

5.长期置放后填充料会变硬，并失去延展性，这将导致离心水泵泄露气体和水。一般状况下，应替换新包裝。

机械隔膜泵的零件和部件很多，受损水平高些。只需定期维护和维护保养，使用寿命就可以延长，这对泵也是有较大的益处。
