The Analysis of the Technical Requirements for Various Sump Pumps

The mechanical seal is a kind of high quality component, which requires high quality of planning, machining and installation. The mechanical seal of the sump pump is also called end face seal. It has a pair of end faces perpendicular to the axis of rotation, with the effect of the fluid pressure and the external elasticity of the sump pump, the pump depends on the support of the auxiliary seal and the other end to adhere to it, and slide relative to the other end to avoid fluid leakage.

In the mechanical seal of sump pump, there are different reasonable requirements of planning, selection and installation. In the process of mechanical seal, we should analyze the various factors of mechanical seal of pump. The mechanical seal of the sump pump is suitable for the requirement of the pump and the requirement of the medium and the smooth condition, so that the pump seal can be guaranteed to work reliably for a long time.

(1)The installation of the shaft end of the ring of the moving ring of the pump and the end face of the sealing gland (or shell) of the seal ring should be Chamfered and trimmed, so as to avoid the damage to the sealing ring of the dynamic ring.

(2) the retrenchment of the pump spring must be carried out according to the rules, which shall not be allowed to be too large or too small, and the error shall be plus or minus 2 mm. If large amount of austerity, then add the face specific pressure, if conflict too much heat, it can form liquid pump sealing surface thermal deformation and speed up the face under wear, if quantity is too small, so the dynamic ring end face specific pressure is insufficient, it can not be sealed.

In the process of mechanical seal, we should analyze the various factors of mechanical seal of pump. The mechanical seal of the sump pump is suitable for the requirement of the pump and the requirement of the medium and the smooth condition, so that the pump seal can be guaranteed to work reliably for a long time. The mechanical seal itself is a kind of high quality component, which requires high quality of planning, machining and installation.
