There are some unreasonable points in the mechanical seal, such as design, selection and installation.(1) The compression amount of spring must be carried out according to the regulations and it is no...

The leakage rate of mechanical seal accounts for more than 50% of all maintenance pumps. The operation of mechanical seal directly affects the normal operation of the pump. Periodic leakage(1) The axi...

(1) The leakage of mechanical seal caused by high pressure and pressure wave, when the design of spring specific pressure and total specific pressure is too large and the pressure in the seal cavity e...

(1) After most mechanical seals of submersible sewage pump are disassembled, the auxiliary seals of static ring and moving ring are inelastic, and some of them have rotted, resulting in a large number...

1. Leakage caused by the flatness damage of sealing surfaceMost of the flatness damage of the sealing surface is caused by uneven slip marks and face cut marks. The cause may be the deformation or dam...

1. Leakage during static test. After the mechanical seal is installed and debugged, the static test should be carried out to observe the leakage. If the leakage is small, it is mostly the problem of t...
