【Industry Sealing Products】Basic Introduction Of Electric Equipment Seals

Power equipment mainly includes two categories: power generation equipment and power supply

equipment. Power generation equipment is mainly power station boilers, steam turbines, gas turbines, hydraulic turbines, generators, transformers, etc. Power supply equipment is mainly transmission circuits, transformers, contact melting devices, etc. of various voltage levels. Mechanical seal is a shaft sealing device for rotating machinery, such as centrifugal pumps, centrifuges (seals), reactors and compressors. Since the transmission pump runs through the inside and outside of the equipment, there is a circumferential gap between the shaft and the equipment, and the medium in the equipment leaks out through the gap. If the pressure inside the equipment is lower than the atmospheric pressure, the air leaks into the equipment.

Therefore, there must be a shaft seal to prevent leakage. There are many types of shaft seals. Since mechanical seals have the advantages of less leakage and long service life, mechanical seals are the main shaft sealing methods in these equipment in the world. The power series high temperature seals produced by Dongsheng Seals have become the commonly used qualified accessories for equipment maintenance of a well-known domestic power group. We have allowed customers to reduce the frequency of equipment replacement of seals, which has produced good economic benefits.
