Application of precision piston rods in hydraulic systems and cylinders

The operation of the precision piston rod is a continuous operation process, so it needs to be lubricated with hydraulic oil to avoid friction and damage to the product. The precision 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 hydraulic precision piston rod improves the surface corrosion resistance and can delay the generation or expansion of fatigue cracks, thus improving the fatigue strength of the cylinder rod. The operation of the piston rod requires the selection of suitable hydraulic oil. The hydraulic oil plays the role of transmitting pressure, smoothness, cooling and sealing in the hydraulic system. The improper selection is the primary cause of the early failure and durability of the hydraulic system.

Precision piston rod has a good application in the machinery industry. Its hardness is about 20 degrees, high frequency and hard optical axis, hardness of quenching/tempering optical axis is about 55 degrees; width is determined by seal size and necessary sliding part length. To decide.

Precision piston rods are important parts of the cylinder, usually made of high carbon steel, hard chrome plated (treated or stainless steel to prevent corrosion and improve the wear resistance of the seal. The cylinder is a closed container The piston can be pressed by the oil and sealed by the seal in the cylinder to convert the hydraulic force into a linear or curved motion. The piston rod of Shenzhen transmits the motion generated by the piston to the actuator.

Generally, the piston rod is hollow, and the hydraulic force is generated from the inside through a closed container formed by the piston and the cylinder, and the movement is caused by the volume change of the liquid. It adopts 45# steel and is processed by grinding machine to achieve the tolerance within 2-4 wires, meet the tolerance requirements of G6H7, and also meet the customer's needs.
