Oil pollution control is an important factor to maintain the stability of the hydraulic system

Hydraulic oil will be slowly oxidized due to long-term high temperature and high pressure. If the oil contains too much impurities or too much moisture, it will accelerate the degradation of the oil, and the coking will gradually adhere to the pipeline like bitumen compound glue. And in the valve body, and the action of the valve will be stuck like a stone over time. Such contaminants are not even easy to filter out with the oil filter, because the gums may be directly produced on the valve body. Cause the oil temperature to rise even more. When the oil temperature is higher than 60~70℃, the hydraulic oil will accelerate the deterioration, corrode the rubber of each part, and the wear coefficient between the oil seals will increase, which will cause oil leakage. In addition to the oil filter, it must be cleaned frequently More importantly, prevent impurities from entering.

 

There are several ways to cause impurities in hydraulic oil:

During the assembly process: impurities in the environment or cutting iron chips.

Hydraulic oil quality: the oil is dirty and the water content is too high (it is recommended to pack the oil in a new barrel)

Wear of valve parts: caused by the oil temperature being too high or the oil viscosity being too low, resulting in ineffective lubrication.

Erosion: The impurities that have entered erode the pipe fittings under high-speed motion.

The wear of other parts: such as the wear of the oil cylinder, piston and oil cylinder. The movement of the pump itself has a sliding phenomenon, so

How many

There will be wear particles, which will be more serious when foreign objects invade.
