　　Product presentation

　　The stator cooling pump is located in the generator stator cooling water system, and its main function is to provide the necessary pressure for the generator stator cooling water to ensure the stable operation of the generator stator cooling water system. Fixed cooling pump assembly seal is a kind of shaft seal device, which is widely used in fixed cooling pump equipment of thermal power plant. 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 fixed cooling pump assembly mechanical seal, as a shaft seal device to prevent leakage, is derived from the basis of non-assembly, which can significantly reduce the equipment leakage phenomenon, ensure the stable operation of equipment, reduce waste and pollution, and its use effect and operation life have better guarantee than the non-set installed seal.

　　Applicable scene:

　　The seal is mainly used for the stator cooling water pump in the generator stator cooling water system of each thermal power plant.
