Key Points For Installing Mechanical Seals For Submersible Pumps

Different mechanical seals need to be selected for submersible pumps according to their different operating conditions. The installation requirements for different mechanical seals are different. Below, we will briefly introduce the installation points of mechanical seals for submersible pumps:
1) The radial runout of the equipment shaft should be ≤ 0.04 millimeters, and the axial displacement should not exceed 0.1 millimeters;
2) The sealing part of the equipment should be kept clean during installation, and the sealing parts should be cleaned. The sealing end face should be intact and undamaged to prevent impurities and dust from entering the sealing part;
3) During the installation process, it is strictly prohibited to touch or tap to avoid damaging the mechanical seal friction pair and causing the seal to fail;
4) During installation, a layer of clean mechanical oil should be applied to the surface in contact with the seal to facilitate smooth installation;
5) When installing the static ring cover, the screws must be tightened evenly to ensure that the static ring end face is perpendicular to the axis;
6) After installation, push the moving ring by hand to make it move flexibly on the shaft and have a certain degree of elasticity;
7) After installation, rotate the shaft by hand and there should be no feeling of weight on the shaft;
8) The equipment must be filled with medium before operation to prevent seal failure due to dry friction.
