[ Industry News ] How to prolong the service life of mechanical seal of centrifugal pump

How to prolong the service life of mechanical seal of centrifugal pump? Listen to what the mechanical seal manufacturer said! 1. The centrifugal pump shaft has a large displacement. During the operation of the centrifugal pump, the sealing surface of the mechanical seal needs to have a certain specific pressure. Only in this way can the role of the mechanical seal be ensured. Therefore, the spring of the mechanical seal must have a certain amount of compression

[ Industry News ] Mechanical seal manufacturer's explanation and selection

The mechanical seal manufacturer explained the selection of mechanical seals. According to the different working conditions and media properties, there are high temperature and low temperature resistant mechanical seals, high pressure and corrosion resistant mechanical seals, particle resistant media mechanical seals, and light hydrocarbon media mechanical seals that are easy to vaporize. Mechanical seals of different structures and materials should be selected according to different uses. Mechanical seals are widely used in various enterprises

[ common problem ] Mechanical seal manufacturer explains seal failure

The mechanical seal manufacturer explained the seal failure. 1. The seal failure is mainly caused by the following three reasons: (1) When the sealing surface is opened and the mechanical seal is repaired, 85% of the seal failure is not caused by wear, but has leaked before wear. As soon as the sealing surface is opened, solid particles in the medium enter the sealing surface under the action of liquid pressure. After the sealing surface is closed, these solid particles are embedded

[ Industry News ] Mechanical seal manufacturer explains the effect, meaning and position of mechanical seal

The mechanical seal manufacturer explained the effect, meaning and position of mechanical seal. The effect of mechanical seal: 1. Improve machine power and reduce energy consumption. 1. Reduce the internal leakage, external leakage and penetration of the machine, and improve the volumetric power of the machine. 2. Reduce conflict loss and improve mechanical power of mechanical seals of machines. For example, double face seal is changed to single face seal, unbalanced seal is changed to balanced seal
