Anti-leakage principle of mechanical seal

　2016-12-05　　

Leakage is a common natural phenomenon in the process of mechanical equipment production and application to mechanical seals. The so-called 'leakage' means that materials run from the inside of the limited space to the outside, or other materials enter the inside from the outside of the space. The material referred to here can be gas, liquid, solid or other physical signs.

The solution of mechanical seal technology is to prevent or reduce leakage. The main reasons for the leakage are the following two factors: one is the gap on the sealing surface; the other is the pressure difference or concentration difference on both sides of the sealing surface. Eliminating or reducing any factor can prevent or reduce material leakage. The methods to reduce leakage, that is, to seal, are mainly as follows: ①Reduce the number of sealing parts; ②Increase fluid flow resistance; ③Add work elements to make the fluid flow in the reverse direction; ④Pump or inject the sealing medium.　　181.html,
