First of all, we must figure out what Mechanical Seals are. In fact, it is a kind of oil seal device that can rotate machinery. It is a pair or more than a pair of end faces perpendicular to the axis of rotation to compensate for the elastic force (or magnetic force) of the educational institution under fluid pressure. With the cooperation of other auxiliary seals and other auxiliary seals, the mechanical equipment seals are kept close and the enterprises are relatively sliding to prevent fluid leakage. The elastic loading mechanism and auxiliary seal of the mechanical seal are the mechanical seal of the metal bellows, which we call the metal bellows seal. In light-duty seals, rubber bellows are also used as auxiliary seals. The elasticity of the rubber bellows is limited, and a spring is generally required to meet the loading elasticity. "Mechanical seal" is often referred to simply as "mechanical seal". The mechanical seal is a device that prevents fluid leakage by keeping at least one pair of end faces perpendicular to the rotation axis under the action of the fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the cooperation of the auxiliary seal, which keeps fit and relatively slides. A shaft sealing device for rotating machinery. Such as centrifugal pumps, centrifuges, reactors and compressors and other equipment. Since the transmission shaft runs through the inside and outside of the equipment, there is a circumferential gap between the shaft and the equipment, and the medium in the equipment leaks out through the gap. If the pressure inside the equipment is lower than the atmospheric pressure, the air leaks into the equipment, so there must be a Shaft seal to prevent leakage. Therefore, its installation engineering quality management requirements are very high, so what can we do to ensure the excellent quality of construction mechanical seal installation services?

Mechanical seal installation precautions:

1. The radial runout of the rotating shaft of the equipment is less than or equal to 0.04 mm, and the movement of the axial mechanical seal shall not be greater than 0.1 mm;

2. The sealing parts of the equipment should be kept clean during the installation process, the sealing parts should be clean, and the sealing end face should be intact to prevent impurities and dust from being brought into the sealing parts;

3. During the installation and construction process, it is strictly forbidden to hit or knock, so as to avoid the mechanical seal friction and damage and the sealing system failure;

During installation, a layer of clean mechanical oil should be applied when the surface is in contact with the seal, so that the installation can be carried out smoothly;

5. When installing the static ring gland, tighten the screws to ensure that the end face of the static ring is perpendicular to the axis;

6. After the installation is completed, push the moving ring by hand, so that the moving ring can be flexibly used and moved on the shaft, and has its own certain time elasticity;

7. After installation, move the shaft by hand, the shaft should have no sense of weight;

8. Before operation, the equipment must be filled with medium to prevent dry friction and seal failure.
