Several basic requirements that the piston rod should meet
Jul 13, 2018

In combination with practical application requirements, there are often strict control standards for the processing quality of the piston rod. This is because the quality of the piston rod processing will directly affect the life and reliability of the entire product. It is usually required that the surface roughness of the finished product is Ra 0.4 to 0.8 μm, and the requirements for coaxiality and wear resistance are very strict.


In general, the piston rod finished product should meet the following basic requirements:

First, the piston rod should have sufficient strength, rigidity and stability to ensure normal use;

Second, the finished product should have good wear resistance and high processing accuracy and surface roughness requirements;

Third, the structural design of the piston rod finished product should minimize the influence of stress concentration;

Fourth, the link should be reliable in use to avoid loosening;

Fifth, the design of the piston rod structure should facilitate the disassembly and assembly of the piston.


As can be seen from the above introduction, the processing quality of the piston rod is very important. In the production process, the process parameters need to be strictly controlled to ensure that the finished product meets the basic requirements.
