Basic introduction of electric power equipment seals

Update:2018-08-08

Power equipment mainly includes two major categories of power generation equipment and power supply equipment. Power generation equipment is mainly power station boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment is mainly transmission circuits, transformers, contactors and the like of various voltage levels.

Mechanical seals are oil-sealing devices for rotating machinery, such as centrifugal pumps, centrifuges (seals), reactors, and compressors. Since the drive shaft runs through the inside and outside of the device, there is a circumferential gap between the shaft and the device through which the medium in the device leaks outward. If the pressure inside the device is lower than atmospheric pressure, the air leaks into the device.

Therefore, there must be a shaft seal that prevents leakage. There are many types of shaft seals. Because mechanical seals have the advantages of less leakage and long life, the world's mechanical seals are the main shaft seals in these equipments. DSH Seals produces electric series high temperature seals: it has become a commonly used qualified equipment for equipment maintenance of a well-known power group in China. We have reduced the frequency of equipment replacement seals and have produced good economic benefits.
