What are hydraulic cylinders made of?

The hydraulic cylinder consists of a honing tube, a piston rod (piston with rod attached) extending from one side (both sides of a double-rod hydraulic cylinder can be used) and a seal kit. There are several different types of cylinders, including welded, tie rod, telescopic and industrial tie rod cylinders. Excavator cylinder including boom cylinder, bucket cylinder and arm cylinder.

Piston Rod Machining Process

 ① Raw Material Selection: Commonly used materials for piston rod machining include 45# steel and 2Cr13 stainless steel. The appropriate material is selected based on the operating environment and performance requirements. For example, a hydraulic piston rod manufacturer, to meet corrosion resistance requirements, chooses 2Cr13 stainless steel for piston rods used in marine equipment. During procurement, the material's quality certificate must be checked to ensure that the chemical composition and mechanical properties meet standards. For instance, the carbon content of 2Cr13 needs to be controlled between 0.16% and 0.25%. ② Blanking and Cutting: The piston rod is cut according to its design dimensions. Common cutting equipment includes saws and lathes. For example, to machine a piston rod with a diameter of 50 mm and a length of 1000 mm, a metal circular saw is used to cut 45# steel bars. Before cutting, the perpendicularity of the saw must be calibrated. After cutting, the flatne...

Functions of the main components of a hydraulic cylinder:

图片
 (1) Cylinder body: The cylinder body is welded from the cylinder barrel, flange, exhaust valve seat, and oil port. It is the main body of the hydraulic cylinder. The surface roughness Ra value of the inner bore is generally required to reach 0.16~0.32μm so that the piston and its seals and supports can slide within it and ensure the sealing effect, reducing wear. The cylinder body must withstand a large liquid pressure, so it is required to have sufficient strength and rigidity. The flange is welded to its end to connect the end cap. The oil port and exhaust valve seat are welded to both ends of the outer circle of the cylinder body and communicate with the inner bore to allow the pressure oil to enter and exit and the air to be discharged. (2) Piston: The piston is the main component of the hydraulic cylinder that converts hydraulic energy into mechanical energy. The size of the effective area of ​​its two end faces determines the magnitude of the thrust and pull. There are seali...
