The influence of operating parameters on the leakage of mechanical seal:

①The influence of seal diameter and speed on leakage: the influence of mechanical seal size and speed on leakage is shown in Figure 3-15. 108u mechanical seal

It can be seen from the figure: the larger the diameter of the seal, the higher the speed, the greater the linear velocity of the seal ring, and the greater the leakage of the gas film seal.

②The influence of the pressure of the sealed medium on the leakage: the influence of the pressure of the sealed medium on the leakage is shown in Figure 3-16.

It can be seen from the figure that when the working gap of the mechanical seal is constant, the higher the sealing gas pressure, the greater the gas leakage.

③The influence of medium temperature and medium viscosity on leakage: The influence of medium temperature on seal leakage is shown in Figure 3-16. It is caused by the influence of temperature on medium viscosity. When the viscosity of the medium increases, the dynamic pressure effect increases, and the thickness of the gas film increases, but at the same time the resistance to flow through the gap between the seal end faces increases. Therefore, its impact on the amount of seal leakage is not great.　　942.html,
