How To Quickly Choose Two Methods Of Sealing?
Mar 21, 2018

How to quickly choose two methods of sealing?

First, determine whether the sealed mechanical equipment is a static seal (fixed) or dynamic seal (reciprocation, rotation, spiral).

◇Host operation direction:
  Whether the type of mechanical equipment is determined to be moving in a reciprocating, rotating, spiral, or statically sealed (fixed) manner.

The key to the seal is:
  Determine if the seal is an inner rod seal or a sealed outer piston. After understanding the mode of operation of the machine, we must determine the application environment of the seal (such as operating temperature, size, and other basic specifications).

Second, clear the working environment of the seal ring, such as the seal operating temperature, pressure and seal size.
  The working temperature of the seal can refer to the following two methods to determine the seal material:
  1. Check the operating temperature of the seal ring according to the instructions of the original machinery.
  2. According to the actual operating temperature to determine whether to use what material seals.

◇ pressure:
  The pressure of the seal can refer to the following three methods:
  1. Check the working pressure of the seal according to the instructions of the original machinery.
  2. Infer the pressure rating by observing the hardness and the structure of the seal used.
  3. Use a hardness tester to test the pressure rating of the seal.

◇ size:
  For a more precise and precise seal size. Please do not choose or order the seals that will be used, because the used seals are affected by other factors such as temperature, pressure and other factors that affect their original size. The best way is to use a metric tool to measure the size of the metal groove where the seal is placed.
