Engineering Cylinder

The hydraulic cylinder is the energy conversion device of the hydraulic system of mechanical equipment. Hydraulic cylinders have various structural forms and are widely used, but most hydraulic cylinders are composed of a cylinder barrel, an end cover and a guide sleeve, a piston assembly, and an exhaust device of a buffer device.

Structural composition and component description of hydraulic cylinder
​
1. Cylinder barrel, end cover, guide bushing
The inner hole of the cylinder barrel generally adopts precision processing and manufacturing processes such as twisting, rolling, boring or honing, and requires a certain surface roughness to ensure smooth sliding of the bracket, piston, and seals, reduce wear, and ensure the sealing effect; the cylinder barrel should Withstand large hydraulic pressure and have sufficient stiffness and strength. The end caps are installed at both ends of the oil cylinder to withstand large hydraulic pressure and form a closed oil chamber with the oil cylinder. The end caps and their connectors should be of sufficient strength. The guide sleeve guides and supports the piston rod or plunger. Some hydraulic cylinders do not have guide sleeves, but the end caps must be replaced after wear. Directly guided by the end cap hole. The structure is very simple.
2. Piston parts
Connection method: In addition to welding, overall structure, taper pin structure, etc., half-ring and threaded connections are also commonly used for the connection between the piston and the piston rod. Semi-ring connections are generally used in places with large vibrations, high strength, complex structures, and inconvenient loading and unloading. The threaded connection has a simple structure and is easy to load and unload. Typically, a nut locking device is required.
Sealing: The piston device plays a good sealing role and is mainly used to prevent hydraulic oil leakage and ensure the normal operation and power transmission of the hydraulic cylinder. Seals can be divided into two categories: static seals and dynamic seals. There are many ways to seal cylinder piston. The piston assembly is oil-resistant, corrosion-resistant, easy to manufacture, easy to disassemble, and automatically improves sealing performance as pressure increases.
