What are the causes of oil leakage in the universal pressure test machine?

Speaking of oil leakage, this problem may occur on many mechanical equipment, and the reasons for oil leakage in different equipment are also different. Presses are divided into electronic types according to different driving forces.Pressure tester, hydraulic pressure tester, electro-hydraulic servo press tester, suitable for metal materials, non-metallic materials and alloy materials. So what is the reason for oil leakage in the universal press test machine?

There are three main points:

1. The quality of the test machine oil cylinder processing is poor. Some oil cylinder manufacturers have not mastered the processing sizes, and some of the assembled oil cylinder oil seals are very loose, some are very tight, and some are relatively backward in processing equipment. In this way, oil leakage will occur in oil cylinders with poor quality.

2. Oil leakage caused by improper operation of the press operator. ifUniversal testing machineOverload or too large dumping angle may sometimes strain the working surface of the hydraulic cylinder and crush the oil seal, resulting in oil leakage.

3. Poor oil seal quality can also cause oil leakage in the hydraulic cylinder. Some oil seals have poor quality and will leak oil after use for a long time. Some even leak oil as soon as they are replaced. If you use multiple oil sealing grooves and multiple oil sealing during maintenance to prevent oil leakage, although the effect is better, it is time-consuming and labor-intensive, so it is still recommended to use a good quality sealing oil cylinder.
