Non-contact gas lubricated mechanical seals use

Blender does not contact with the gas lubricated mechanical security seals (low speed) sold in the market, there are already more than 10 years. In the past 10 years, has made a series of experiences. This paper summarizes a number of important insights. When used correctly in the appropriate purposes, the mixer gas seal can help the user to improve quality and increase product purity.
When discussing the mechanical seal, the most important thing is to figure out the differences between various sealing systems. Mechanical seals are three basic types: fluid lubricated mechanical seals, gas lubricated mechanical seals and touch off style or called non-contact gas lubricated mechanical seals.
These types of mechanical seals difference is in the fluid-lubricated sliding surface of the seal between the fluids. These bolt seal are usually applied mixed friction purpose mixer. For dry running seals, two sliding surfaces in direct contact with each other. On the other hand, does not contact the gas-lubricated mechanical seals, in the operation of the sliding surface is not in direct contact. There are 1 ~ 5μm wide gap separating the surface, which is why this is often referred to as the seal seals from seal causes. When referred to the gas damping double seals should have this distinction. Here we will discuss only non-contact gas lubricated mechanical gas seals.
