Non-contact gas lubricated mechanical seals use

This article summarizes the mixer contacting gas lubricated mechanical security seals important insights , the proper use of appropriate purposes mixer gas seal for the user to improve the quality of great significance to improve product purity . Discusses the mechanical seal is very important to clarify the distinction between various sealing systems mainly basic fluid lubrication liquid hybrid bearing housing with common shaft axis
Blender does not contact with the gas lubricated mechanical 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 meter seal difference is in the fluid -lubricated sliding surface of the seal between the fluids. These seals are usually applied mixed friction purpose mixer. For dry running seals, two sliding surfaces in direct contact with each other . On the other hand , the non-contact 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.
