The piston rod is a connecting component that is used in some reciprocating actuators. It mainly needs to withstand a certain axial force and reciprocate at a certain speed to work externally. In this way, it is particularly important to select the sealing structure and the sealing ring for the piston rod.

 

Because the seal structure and seal are key components in the reciprocating actuator. It is not only related to the leakage problem, but also the piston rod will affect the performance and life of the entire machine. So what factors should be considered when using the sealing structure and sealing ring for the piston rod?

 

The following factors should be considered when selecting the sealing structure and sealing ring for the piston rod:

 

1, working temperature;

 

2. Working medium viscosity;

 

3. The size of the work pressure;

 

4. Allowable leakage;

 

5. The speed of movement of the piston rod;

 

6, the starting friction of the piston rod;

 

7, the sealing ring on the piston rod tolerance and groove size requirements.

 

The content described above is that the piston rod should be considered for its sealing structure and sealing ring. In addition, the most important thing for the piston rod to use the sealing structure and the sealing ring is to choose according to the actual situation. For example, unlike piston rod applications, the choice of seals and seals may vary.
