It is strictly forbidden to work the centrifugal pump in the evacuated state, because the centrifugal pump works in the evacuated state, not only the vibration is severe , And also affect the life of the pump, so special attention must be paid. (2) Check the shaft seal and each joint sealing surface for leakage; (3)
Check whether the cooling system and sealing lubrication system are unblocked, and whether the pressure and temperature are within a reasonable range; (4) Check the smoothness of operation and whether there is vibration; 5) Check whether the coupling, safety cover, and frame bolts are loose; (6) Check the bearing temperature, which generally cannot exceed 70??75?. If the parts are damaged, they should be replaced in time.
The user shall use oil products in strict accordance with the lubrication regulations of chemical centrifugal pump equipment. (4) When the chemical centrifugal pump runs for a certain period of time, its bearings should be lubricated and maintained to ensure its service life., so as not to damage the flow parts of the pump and block the impeller flow path, which makes the pump unable to work normally. 2. During the operation of the pump, there are many problems that affect the efficiency of corrosion-resistant chemical pumps. (3) The operation process of the chemical centrifugal pump should be guarded by a special person, so that once a problem occurs, it can be dealt with in time.
Check the operation status of the centrifugal pump every day, and deal with any problems in time. It is very directly related, so it is very necessary to strengthen the daily maintenance and maintenance of chemical pumps. Routine maintenance and maintenance of corrosion-resistant chemical centrifugal pumps: 1. In addition, the Deep Well Pumps Factory pump cannot work for a long time under cavitation conditions, because this will cause great damage to the pump. The specifics are: (1) For the mechanical seal lubrication of chemical centrifugal pumps, the main requirement is that there should be no solid particles such as lubricating oil
