The closed cooling pump is located in the closed cooling water system, the function is to provide cooling water for the auxiliary equipment of the unit to ensure the normal operation of the auxiliary equipment and system, and to provide shaft sealing water for the open circulating cooling pump and water chamber vacuum pump. Closed cooling pump non-assembly machine seal is a kind of shaft seal device, widely used in closed cooling pump equipment in thermal power plants. Because the transmission shaft passes through the inside and outside of the equipment, thus forming a circular gap between the shaft and the equipment, causing the medium in the equipment to leaks outward through the gap. Therefore, the closed cooling pump assembled
applicable scene:
The seal is mainly used for the closed cooling water pump in the closed cooling water system of each thermal power plant.
