What is the color change of the piston rod of the cylinder?

The cylinder piston (piò ché ng) is sometimes used to cause discoloration of the individual surfaces of the cylinder rod due to oil and external factors. phenomenon. The 45# piston rod connects the piston and the crosshead to transmit the force acting on the piston and drive the piston to move. The cylinder piston rod wear ring can improve the guiding of the cylinder, reduce the wear of the piston seal and reduce the frictional resistance. The hydraulic piston rod cylinder, the piston rod (cylinder rod), the piston and the end cover are composed of several parts. The 45# piston rod supports the connecting parts of the piston work. Most of them are used in the cylinder and cylinder movement executing parts. It is a moving part with frequent movement and high technical requirements. The hollow piston rod refers to a hollow piston rod having an annular cross section. Then what is the discoloration of the cylinder rod? What should be done when this phenomenon occurs? (chǔ lǐ) Common causes of discoloration of the piston rod of the cylinder: 1. Hydraulic system (high temperature) State, in this way, the working cylinder rod in the high temperature state, frequent frequency and low temperature environment, it is easy to cause discoloration. 2. During maintenance, if hydraulic oil is replaced, discoloration may occur. Because the hydraulic oil has a different character and performance of the extreme pressure anti-wear additive, it sometimes shows discoloration of the piston rod within a few days of just changing the oil. 3. During the electroplating process of the piston rod, due to uneven temperature control (jūn yú n), cracks appear on the surface of the plating layer of the piston rod during the later work (jūnlìe) . Especially when the surface of the piston rod is observed with a high magnification magnifying glass, the presence of irregular small cracks can be seen. The treatment method of cylinder cylinder rod discoloration: 1. Ensure that the hydraulic system can maintain a proper temperature condition to avoid long-term high temperature. 2, try to use the same hydraulic oil, can effectively avoid discoloration of the piston rod. 3. If the piston rod is cracked during the plating (jūnl & igrave; e), the surface of the piston should be repaired.
