The centrifugal pump YCZ50-250A is used for water circulation in the cooling water system of the generator stator. It works by using the rotation of the impeller to cause centrifugal movement of water. The basic structure of YCZ50-250A centrifugal pump is composed of impeller, pump body, pump shaft, bearings, sealing ring, packing box, etc. Yoyik will explain in detail one of the parts that often need to be replaced: mechanical seals.

The function of mechanical seal is to ensure that the centrifugal pump YCZ50-250A does not leak during operation. Its dynamic and static rings mainly play a sealing role. The moving ring rotates together with the pump shaft, while the stationary ring is fixed in the gland and prevented from rotating by an anti rotation pin. Reliable sealing is achieved by maintaining a close fit between the contact end faces of the moving and stationary rings during movement. During long-term operation, the sealing state is very stable and the leakage is very small.

During the operation of centrifugal pump YCZ50-250A, the flushing of mechanical seals is an important issue. It is necessary to ensure that the mechanical seal has sufficient water flow for flushing, and the temperature should not be too high. For pumps that transport media containing solid particles or high-temperature media, it should be considered to install an auxiliary cleaning mechanical seal system outside the pump, including filters, coolers, etc. This is very effective in ensuring the normal operation of the mechanical seal and extending the pump operating cycle.
