How to ensure the excellent quality of mechanical seal equipment

　2016-11-21　　

　　 The so-called mechanical seal is actually a kind of oil sealing equipment for rotating machinery. It is the effect of fluid pressure and compensation of tissue elasticity (or magnetic force) and auxiliary sealing on one or more end faces that are straight to the axis of rotation. Under the cooperation, keep the paste and merge relatively sliding to avoid fluid leakage. Therefore, the equipment quality requirements are very high, and there are a series of precautions during the equipment process.

　　1. The radial runout of the shaft of the equipment should be ≤0.04mm, and the axial runout should not be greater than 0.1mm;

　　2, the sealing part of the equipment should be kept clean when the equipment is in the equipment, the sealing parts should be cleaned, and the sealing end face should be intact to prevent impurities and dust from being brought into the sealing part;

　　3. It is forbidden to hit or hit during the equipment process to avoid damage to the mechanical seal and seal failure;

　　4. When the equipment is in contact with the seal, a layer of clean mechanical oil should be applied to the surface, so that the equipment can be smooth;

　　5. When the equipment static ring gland is tightened, it is necessary to tighten the screws evenly to ensure the straightness of the static ring end face and the axis line;

　　6. Push the moving ring by hand after the equipment, which can make the moving ring move sensitively on the shaft and have certain flexibility;

　　7. After the equipment is turned on the shaft by hand, there should be no sense of weight on the shaft;

　　 8. It is necessary for the equipment to be filled with medium before working to avoid dry conflict and seal failure.

　　The mechanical seal equipment is ready to ensure the stable function of the relevant machinery in the subsequent use process.　　2.html,
