The diaphragm in the mechanical equipment diaphragm pump is a perishable component and needs to be replaced on time. If the customer does not pay attention to replacement during application, it will cause safety accidents in case of damage. Therefore, Depamu kindly reminds that it is very important to replace the diaphragm on time.
Generally speaking, the diaphragm should be replaced after 8000 hours of operation, otherwise it will lead to fatigue damage, cracking, etc., which will endanger the service life of the facilities, cause environmental pollution of lubricating grease, drive the piston rod cylinder, and cause damage to key facilities.
During the operation of the diaphragm pump, the camera and hydraulic transmission system shall be regularly maintained according to the appropriate process to avoid common faults of the oil discharge camera, blockage of the supplied oil and oil pipeline or common faults of the pipeline gate valve, arrhythmia caused by battery charging and charging and discharging oil, and promote water accumulation. Working pressure variability; Strictly implement the regulations on the operation of diaphragm pump and working pressure module, and overweight operation is strictly prohibited; Check the unbalanced in-situ stress caused by the change of working pressure at the inlet and outlet of the diaphragm pump of the check valve of the diaphragm pump. The in-situ stress will cause the diaphragm to crack. Be sure to replace it immediately.
There are many types of mechanical equipment diaphragm pumps, but you must pay attention to regular inspection and replacement of spare parts.
1. The pump body is made of pig iron, which is easy to crack due to mechanical equipment stress or internal stress. Maintenance is required. If the damage is more serious, replace it immediately. Some safeguard measures can be taken for the pump body to reduce damage.
2. The pump shaft is generally made of high carbon steel, which is very easy to be damaged after long-term application. Cracks, bends, motor shaft wear, external thread damage, etc. are likely to occur, and fracture safety accidents may occur, which should be replaced immediately.
3. Impeller is the key component of pump. Cracks will occur on the impeller. Because of cavitation, holes or holes are formed in the surface layer. Long term etching will soften or partially wear the cutter head, and even be broken by slag. If you are looking for it, please replace it with a new one.
4. The mouth ring is also called leakage reduction or wear reduction ring, which is more convenient for wear. Wear can be repaired better and cannot be replaced immediately. When replacing a new leakage reduction ring, its inner diameter shall be equipped according to the diameter of the impeller channel.
5. After long-term placement, the filler will harden and lose ductility, which will cause gas and water leakage from the centrifugal pump. Generally, the package shall be replaced with a new one.
There are many parts and components of mechanical equipment diaphragm pump, and the damage level is higher. The service life can be increased by regular maintenance, which is also of great benefit to the pump.
