Oil cylinder is a kind of equipment used to store or transport liquid, gas and powder, which is widely used in petroleum, chemical, electric power, metallurgy and other industries.

The manufacturing and assembly of oil cylinder involves many links such as material selection, equipment manufacturing, process flow, etc, Oil cylinder manufacturer The manufacturing and assembly process of oil cylinder will be described in detail.

1. The manufacturing of oil cylinder needs to select appropriate materials.

Common cylinder materials include carbon steel, stainless steel, alloy steel, etc., and appropriate materials shall be selected according to the specific use environment and requirements.

The selection of materials shall consider corrosion resistance, strength, high temperature resistance and other factors to ensure the quality and performance of the oil cylinder.

2. The preliminary purpose of manufacturing oil cylinder is to cut and process materials.

According to the design drawings, the selected materials shall be cut into suitable sizes and shapes, and the surface shall be treated.

In the process of cutting and processing, special equipment such as plate shears and CNC cutting machines are required to ensure the accuracy and quality of cutting and processing.

3. Next, weld and assemble the oil cylinder.

The oil cylinder is generally composed of cylinder, head, support, flange and other components, which need to be welded and assembled.

Welding is an important link to connect parts together, and the welding quality directly affects the strength and sealing of the entire cylinder.

Generally, various welding methods are used, such as manual arc welding, gas shielded welding, etc.

After welding, non-destructive testing, such as X-ray testing and ultrasonic testing, is also required to ensure the quality of welding.

4. During the assembly process, the cylinder and head shall be paired and sealed with appropriate sealing materials.

Next, install the bracket and flange, and connect and adjust them according to the design requirements.

At the same time, lubrication and cleaning are also required to ensure the normal operation and use of the oil cylinder.

5. After assembly, test and inspect the oil cylinder.

The contents of test and inspection include appearance inspection, dimension measurement, pressure test, reliability test, etc.

Among them, pressure test is a very important item, mainly to verify the pressure bearing performance of the cylinder.

The hydraulic test or pneumatic test is usually used to fill the oil cylinder with water or gas,

Pressurize to the pressure required by the design, and check whether there is leakage and deformation.

6. Surface treatment and painting of oil cylinder.

Surface treatment includes rust removal, polishing, sand blasting, etc. to remove impurities and improve surface quality.

The purpose of painting is to improve the corrosion resistance and aesthetics of the oil cylinder. Generally, the painting method is used.

To sum up, the manufacturing and assembly process of oil cylinder includes many links such as material selection, cutting, welding and assembly, testing and inspection, and surface treatment. The quality and process control of each link are crucial. Only when each link is fine and rigorous, can the cylinder with reliable quality and excellent performance be manufactured.
