Piston rod sealWith regard to the role of the piston rod, the piston rod action is connected to the support part of the piston rod, most of the applications in the cylinder, the cylinder moves the actuator member, the movement is the frequent moving parts, the technical requirements are high. Hydraulic cylinder, through the cylinder, piston rod and other parts of the piston cap. Processing quality directly affects the life and reliability of the entire product. High processing requirements of the piston rod, surface roughnessRa0.4 is 0.8 μm, concentricity, and high wear resistance. The basic feature of the cylinder rod is the slender shaft processing, processing difficulty is big, has been troubled by the processing personnel.
Piston rod sealRegarding the role of the piston rod, the piston rod can be mainly used for the manufacture of piston rods through hydraulic and pneumatic, engineering construction machinery, and automobile production., The guide post of plastic machinery, the roller shaft of packaging material machinery, printing electronic machinery, the axis of textile enterprise machinery, conveying machinery, and the linear optical axis for linear motion.
Piston rod sealRegarding the role of the piston rod, the outer diameter difference of the piston rod can have an appropriate small gap with the diameter of the bearing. Under precise movement, we can adjust the tolerance of the solid shaft so that no pressure and clearance will be generated. If the shaft is not round or straight, the solid shaft is periodically pressurized, which not only reduces the life, but also does not move in a straight line. Therefore, we must pay attention to the choice. If the piston rod changes color, the system has high temperature.
Piston rod sealRegarding the function of the piston rod, the piston rod may suddenly drop in a high temperature state and a low temperature environment in winter. If you use other brands of hydraulic oil during maintenance, it will not change color in a short time, because this oil is the reason for adding extreme pressure and anti-wear additives. If the temperature control of the piston rod is not good, it will cause the coating cracking.
