The O-ring of centrifugal pump shaft sleeve HZB253-640-03-08 is a sealing ring specifically used for the booster pump shaft sleeve, which has high wear resistance and corrosion resistance. It is mainly used in the shaft sleeve of the front pump, playing a sealing and leak proof role.

The main function of the centrifugal pump is to increase the pressure at the inlet of the feed water pump and prevent cavitation. Due to the low speed of the front pump (1490r/min) and the adoption of a double suction structure, it has well anti cavitation ability. The front pump is a double suction single row closed single-stage centrifugal pump, with a horizontal open structure on the casing. The outlet and inlet of the pump are both located at the lower part of the casing, which is conducive to the maintenance of the front pump.

The following is the application and function of O-ring of centrifugal pump shaft sleeve HZB253-640-03-08:

1. Sealing function: Through its special shape and material, the O-ring can effectively seal the gap between the pump shaft and the shaft sleeve, prevent liquid leakage, and ensure the normal operation of the pump.

2. Wear resistance: The HZB253-640-03-08 O-ring is made of wear-resistant material, which has high wear resistance and can withstand the wear between the pump shaft and the shaft sleeve, extending the service life of the shaft sleeve.

3. Corrosion resistance: This O-ring has good corrosion resistance and can resist the erosion of various corrosive media, ensuring that the sealing performance of the pump shaft sleeve is not affected.

4. High temperature resistance: The HZB253-640-03-08 O-ring has high temperature resistance and can maintain stable sealing performance in high-temperature environments, ensuring the normal operation of the pump.

5. Easy installation: The shape and size design of the O-ring make it easy to install on the pump shaft sleeve without the need for special tools, and the installation process is simple and fast.

In summary, the O-ring of centrifugal pump shaft sleeve HZB253-640-03-08 plays a crucial role in sealing and leak prevention in pump applications, ensuring the normal operation and service life of the pump.
