Explosion-proof fan use method

→Explosion-proof fan Overview Explosion-proof fan is a fan that is used in places where XX is dangerous. In addition to the fan characteristics required by working conditions, explosion-proof fan must meet the requirements of explosion protection. Explosion-protected fan characteristics Explosion-proof fan must use explosion-proof motor; on the other hand, explosion-proof fan's flow components (impeller, volute, etc.) must be made of soft and hard materials, usually between rotating parts and fixed parts. It must be soft and hard to prevent friction or collisions between components when a fault occurs. The more common material cooperation is that the blade, front plate, rear plate, and blade rivets of the impeller are made of hard aluminum of 2A01 material, and the spiral case is made of galvanized plate. If the impeller is made of a hard aluminum material that does not meet the strength requirements, it is also possible to use a galvanized steel impeller and a thin hard aluminum lining on the surface of the volute.

KVK-UN

Overview

UN type Seals are one-way acting Sealing elements, in hydraulic cylinders, mainly used for piston rod sealing, in many applications, especially in mobile machinery, automobiles, forestry and mining machinery, under harsh working conditions , has good mechanical properties. In heavy-duty occasions, it has a very good effect when used in conjunction with the RS-type step Seal.

advantage

In addition to the advantages mentioned above, as well as the advantages of good sealing effect and easy installation, the Sealing Element also has the advantage of low friction in the low pressure range.

Scope of application

It is suitable for piston rod sealing and has a wide range of applications, especially in hydraulic equipment such as mobile machinery, automobiles, forestry and mining machinery.
