Structural type of components of hydraulic piston seals?

Hydraulic cylinder?An industry term that everyone is familiar with, but do you know what components the hydraulic cylinder in the hydraulic piston seal is made?Dongsheng seal tells you that the hydraulic cylinder in the hydraulic piston seal can be roughly divided into five components: cylinder block assembly, piston assembly, sealing device, buffer device and exhaust device, so do you know that the large components of these hydraulic cylinders are composed of those small components?The following is a detailed introduction to what small components are made up of each major component!

 

Hydraulic cylinder piston structural assembly in hydraulic piston seal (As shown in Figure 1).The piston assembly includes the main parts such as the piston and the piston rod, and the connection type between the piston and the piston rod (As shown in Figure 1).

 

1. thread connection:

 

Its structure is simple and easy to install and disassemble, But nut anti-loosening device is required under high pressure and large load;

 

2. half ring connection:

 

It is complex in structure and inconvenient in assembly and disassembly, but it works reliably and can withstand large loads and vibrations;

 

3. welding connection:

 

It has small axial size, easy processing, but inconvenient disassembly.

 

In addition, the piston and piston rod in the hydraulic piston seal also have an integral structure, but it is only suitable for occasions where the size is small (Working Environment).The piston is generally made of wear-resistant cast iron, while the piston rod is hollow and solid, mostly made of steel.
