How to choose the material of quenched and tempered piston rod
In order to increase the service time of the piston rod and reduce the wear of the piston rod, 38crmoalan alloy structural steel is selected as the blank.
What is the processing technology of piston rod?
The piston rod is produced by rolling, because the residual compressive stress in the surface layer is left in the surface layer, which is conducive to the closure of the micro cracks in the surface layer and hinders the development of sedimentation. In order to improve the surface corrosion resistance, the piston rod can slow down the fatigue crack or expansion, so as to improve the fatigue limit of the hydraulic cylinder rod. According to the rolling forming, a layer of cold work hardening layer is produced on the rolling surface layer, which reduces the ductility and plastic deformation of the cutting pair touching the surface layer, thus improving the wear resistance of the surface layer of the hydraulic cylinder rod and preventing the scald caused by cutting. After rolling, the reduction of roughness value can improve the matching characteristics. Together, the friction damage to the seal ring or hydraulic seal is reduced when the rod piston of the hydraulic cylinder moves, and the overall service life of the hydraulic cylinder is improved.
Precautions for installing piston rod
The piston rod is basically all the connecting parts which are often used in mechanical manufacturing. Therefore, we must attach great importance to its installation problems. Otherwise, if the installation is wrong, it will lead to the normal operation of machinery and equipment. So let's share the main problems to pay special attention to when installing the piston rod of the equipment.
Maintenance method of piston rod
Many processing plants need to use the piston rod, which needs maintenance after a period of time. However, many newcomers often do not know how to maintain the piston rod. Piston rod manufacturers share maintenance methods with you.
In which cases insulated flange is required
Usually, there are some dangerous factors in pipeline connection, including leakage, galvanic corrosion and static electricity. These are signs of accidents. Therefore, ordinary flange connection is not enough. It is necessary to use insulated flange with insulation characteristics, which is used in the environment of insulated flange shared by everyone.
What are the anticorrosion methods of welding flange
Many, but in flange, flange every welding process to consider anti-corrosion method, because this directly affects the sealing performance of the pipeline connection. What is the anticorrosion method of welding flange joint with you.
