pump mechanical sealing is a sealing device used for the closed connection between the pump body and the rotating shaft. It consists of two main parts: a rotating sealing surface driven by a rotating shaft and a fixed sealing surface installed on the pump body. The contact surfaces between these sealing surfaces are very close and sealed by gaskets or O-rings.
pump mechanical sealing are an important component of pumps, and their quality directly affects the performance and service life of the pump. It is suitable for various liquid pumps, such as water pumps, petroleum pumps, and chemical pumps.
Mechanical seals are usually highly reliable and have a long lifespan, but they require proper installation and maintenance to achieve optimal performance. They usually require regular replacement to ensure the normal operation of the pump.
The function of pump mechanical sealing is:
1. Prevent liquid leakage in the pump and ensure a clean and hygienic working environment for the entire system.
2. Reduce energy loss, improve pump efficiency and operational reliability.
3. Extend the service life of the pump, reduce maintenance frequency and costs.
4. Prevent solid particles and particulate matter inside the pump from corroding the pump shaft and sealing surface, and improve the service life of the pump.
5. Under high temperature and pressure, prevent liquid evaporation and gas infiltration inside the pump, thereby preventing damage to the pump shaft and sealing parts due to overheating.
