The important proportion of mechanical seal technology in modern fluid engineering technology:

Although the weight of mechanical seal technology in modern fluid engineering technology is not too large, it cannot be ignored. mainly reflects in:

(1) Although mechanical seal is not a decisive technical field, it is a key technology in some occasions. For example, the circulating water pump of a nuclear power plant can be changed from a shaft-sealed pump to a non-shaft-sealed pump for the sake of safety and reliability. This case is sufficient to illustrate the important role of sealing technology.

(2) Although the mechanical seal is not big, it is just a basic component in the machine, but it can determine the performance of the machine (safety, reliability, etc.). In all kinds of mechanical equipment, once the mechanical seal fails, it will not only affect the normal operation of the equipment, but also burn or explode, and even cause major safety accidents such as machine destruction.

(3) The workload of mechanical seals in the maintenance of moving equipment accounts for more than half of the work. Through the investigation of several petrochemical companies at home and abroad, it was found that mechanical seals accounted for a large proportion of the equipment maintenance workload. Especially in centrifugal pumps, approximately 70% of maintenance costs are due to seal failures.
