Can someone who knows about hydraulic cylinders come in and help me? It is best to understand the products of Jiangsu Hengli High Pressure Cylinder Company

Its main components are:

Chinese: cylinder English: TUBE

Chinese: piston rod English: ROD

Chinese ：Cylinder cover English: ROD COVER

Chinese: Piston English: PISTON

Chinese: Seal English: SEAL

1. The cylinder tube (TUBE) consists of four Parts composed:

1. Cylinder body 2. Flange 3. Cylinder bottom 4. Bushing

2. Piston rod (ROD) consists of three parts:

< p>1. Rod body 2. Earring 3. Bushing

It consists of the above parts; the inside of the cylinder is divided into two parts by the piston, which are the large cavity and the small cavity;

Large cavity Refers to the inner cavity of the cylinder after the piston rod is fully extended;

The small cavity refers to the inner cavity of the cylinder and rod after the piston rod is fully extended;

Due to the viscosity of the hydraulic oil Relatively high, the compression ratio is very small. When oil enters the cylinder bottom oil port, the piston will be pushed to make the cylinder head oil port discharge oil. The piston drives the piston rod to extend or retract, and vice versa.

The working principle of a hydraulic cylinder

Let’s first talk about its five basic components: 1-cylinder barrel and cylinder head, 2-piston and piston rod, 3-sealing device, 4 -buffer, 5-exhaust device.

The working principles of each type of cylinder are almost similar. Take a manual jack as an example. The jack is actually the simplest oil cylinder. The hydraulic oil enters the cylinder through a one-way valve through a manual booster (hydraulic hand pump). At this time, the hydraulic oil entering the cylinder cannot go back due to the one-way valve, forcing the cylinder rod upward, and then the hydraulic oil continues to flow during work. Continuously enter the hydraulic cylinder, and continue to rise like this. When it is about to fall, open the hydraulic valve to allow the hydraulic oil to return to the tank. This is the simplest working principle. Others are improved on this basis. The difference between the cylinder and the oil cylinder The principle is basically the same.
