The small machine pump in the process industry is the main rotating equipment commonly used, and more than 9o% of the liquid relies on the normal operation of the small machine pump to maintain the safe operation of the whole production process. With the development of the process industry and the improvement of pump technology reliability, most of the modern design uses a single series of machines and equipment. Therefore, in normal production, it is especially important to ensure the quality of maintenance during maintenance and overhaul of the pump. This requires the maintenance and maintenance personnel to master the maintenance technology, so that the pump can be maintained or restored to the specified function.
The small machine pump is the material basis for the factory to improve economic efficiency. Through the overhaul, it eliminates the defects and hidden dangers in the operation of the pump. It also consolidates the material foundation of the factory and ensures the safe and stable long-term operation of the plant. . (10,000 fan)
Generally, the maintenance of commonly used small pumps should include the following:
1) Review the alignment of the motive and the pump. If there is a big difference from the original data, it must be readjusted.
2) Demolition check the rotor, shaft and bearing wear of the pump and perform non-destructive testing.
3) Perform macro inspection and inspection on the parts of the pump.
4) Perform dynamic and static balance correction on the rotor and test the end face jump on the machine tool.
5) Check the mouth ring to eliminate the worn gap and improve the efficiency of the pump. (FRP acid mist purification tower)
6) Adjust the back of the impeller and other parts of the gap.
7) Check and replace the seal.
8) Clean and purge any debris or dirt left in the pump.
9) Eliminate the leakage of the pump and auxiliary parts and check the lubricating oil system.
10) Insulation, descaling and painting of the whole pump.
