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. Stator cooling pump non-assembly mechanical seal is an shaft sealing device, widely used in stator 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, stator cooling pump non-assembly mechanical seal can significantly reduce the leakage phenomenon, ensure the stable operation of the equipment, and reduce waste and pollution.
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.
