First of all,we should figure out what is the mechanical seals, it is a kind of rotating machinery oil seal device, it is a pair or more than a pair of mechanical seal face straight on rotation axis in fluid pressure and counter the effect of tissue elasticity (or magnetic force) and assisted with the cooperation of seal, keep post merger and relative sliding and avoid fluid leakage.Therefore, the quality requirements of mechanical seals are very high. What should we do is ensuring the excellent quality of mechanical seals
Notes for equipment of mechanical seals:
1. The radial pulse of the rotating shaft of the equipment should be less than or equal to 0.04 mm, and the axial movement momentum should not be greater than 0.1 mm;
2. The sealing parts of the equipment shall be cleaned when the equipment is in use, and the sealing parts shall be cleaned.
3. In the process of equipment, it is strictly prohibited to touch or strike, so as to avoid the sealing failure due to the damage caused by mechanical seal conflict;
4. When touching the surface of the equipment with the seal, a layer of cleaning mechanical oil shall be applied to the surface to smooth the equipment;
5. When the static ring gland of the equipment is pressed, it is necessary to tighten the screw evenly to ensure the straight demand of the end face and axis of the static ring;
6. Push the moving ring by hand after the equipment, which can make the moving ring move sensitively on the axis and have certain flexibility;
7. After the equipment, there should be no sense of weight on the manual wheel rotating shaft and rotating shaft;
8. It is necessary for the equipment to fill the medium before working, so as to avoid dry conflict and make the seal fail.
