The importance of mechanical seals for pumps

【Summary】：The weight of mechanical seal technology for pumps in ancient fluid engineering technology is not too large, but it plays an important role in the governance of the facility and should not be underestimated.
Pump mechanical seal technology in ancient fluid engineering technology accounted for the weight of not too much, but it plays an important role in the governance of the facility, should not be ignored.
 
1. pump mechanical seal does not belong to the field of technology with decisive significance, but in some places is the key technology. For example, the nuclear power plant’s circulating water pump for safety and reliability, can be changed to a shaft seal pump, this example can clarify the important role of sealing technology.
 
2. Pump mechanical seals are not large, just a fundamental part of the machine, but it can resolve the functional safety and reliability of machine operation. In a variety of mechanical facilities, once in effect, will not only affect the normal task of the facility will also produce a fire or explosion, and even the formation of serious safety incidents such as machine destruction.
 
3. Pump mechanical seals in the maintenance of dynamic facilities, the task accounts for more than half. After a survey of several international and foreign petrochemical enterprises. Found that the pump with mechanical seals in the facility repair tasks accounted for a large proportion of the task. Especially in the centrifugal pump, about 70% of the repair costs are due to seal failure.
