Oil cylinder is a container used to store liquid, which is generally made of metal and is used in industrial production Hydraulic system 。
In order to ensure the safety and reliability of the oil cylinder in use, it is necessary to conduct physical performance inspection.
Common inspection standards for physical performance of oil cylinder mainly include the following:
1. Withstand voltage test:
When the oil cylinder bears hydraulic pressure, it needs to have a certain pressure resistance.
Static pressure test and dynamic pressure test are usually carried out to test the deformation, leakage and leakage under different pressures.
2. Wear resistance test:
The oil cylinder will be impacted and rubbed by the hydraulic medium during operation, so it needs to have certain wear resistance.
The wear resistance of the surface is usually evaluated by simulating the friction test under actual working conditions.
3. Corrosion resistance test:
The oil cylinder is often exposed to various hydraulic media and needs to have certain corrosion resistance.
Immersion test and corrosive medium impact test are usually conducted to evaluate its stability under different corrosion conditions.
4. Strength and stiffness test:
As a component bearing hydraulic pressure, the oil cylinder needs to have certain strength and stiffness.
The strength and stiffness under external load are evaluated through tensile test, impact test and torsion test.
5. Sealing performance test:
The oil cylinder shall have good sealing performance when working to prevent liquid leakage.
The sealing performance under different working conditions is usually evaluated through sealing test and leakage test.
The above are common inspection standards for physical performance of oil cylinder, which are different Oil cylinder manufacturer There may be some slight differences with different types of cylinders. The physical performance inspection shall be carried out in strict accordance with the corresponding standards to ensure the safety and reliability of the oil cylinder in use.
