Rescue measures for loose connection between stainless steel piston rod and piston

Before the use of the hydraulic cylinder, the stainless steel piston rod and piston must be connected. During the use, due to some reasons, the stainless steel piston rod and piston may become loose. If the connection between the stainless steel piston rod and the piston is loose, we must deal with it, otherwise the hydraulic cylinder may not work normally

Small screws can be used to fasten the threads connecting the piston and the stainless steel piston rod to prevent loosening; The connection between the stainless steel piston rod and the piston can be prevented from loosening by designing the thread structure and then locking it with a large nut at the end. A small skirt can be properly left at the front end of the piston, and a small notch can be left on the piston rod, and then the piston skirt can be knocked to prevent loosening.

Thread glue can be directly used to prevent loose connection between piston rod and piston. For example, when the hydraulic cylinder is under normal working conditions, the piston and piston rod will be connected by thread. However, when the working pressure is high or the load is large and the diameter of the piston rod is small, the thread of the piston rod may be overloaded. Then, the nut fixing the piston may vibrate, so non threaded connection is required.

In order to meet the production demand, the hardness of stainless steel piston rod is very important. The process is related to the material. In order to ensure the qualified hardness, there are different types of stainless steel piston rod in the process of processing and material selection. If necessary, you can check the hardness of different materials, plating, rolling, heat treatment and other processes.

The load borne by the stainless steel piston rod affects its movement. Because the piston rod is constantly moving during operation, the load of the piston rod needs to be understood in order to avoid various damages. The common saying is that the load of the piston rod is not large. The piston rod is made of 45# steel, and the load is very large. The 40Cr series is used.
