R928006971 high-quality industrial high-pressure oil return Filter Element is made of our company's high-quality glass fiber material and stainless steel round mesh frame. It has high strength, corrosion resistance, strong dirt holding capacity, good filtration performance and long service life. The inner glass fiber filter paper is folded to increase the filtering area and improve the filtering efficiency, and the accuracy is kept below 5 microns. R928006971 high-pressure oil return filter element is usually used in environmental protection, petrochemical, electric power, metallurgy, shipbuilding, engineering, machinery, agricultural machinery, automobiles, railways, medicine, and chemical industries.

Replacement time of Hydraulic Filter Element:

1. Hydraulic excavators generally need to replace the hydraulic oil after 2000 hours of operation, otherwise it will pollute the system and cause system failures. According to statistics, about 90% of hydraulic system failures are caused by system pollution.

2. On the basis of checking the color, viscosity and smell of the oil, the oil pressure and air humidity should also be checked. If you are working in a higher altitude and lower temperature environment, you must also pay close attention to the carbon content, colloids (olefins) and sulfides in the engine oil, as well as the impurities, paraffin and moisture content in the diesel.

3. In special circumstances, if the machine uses low-grade diesel (the sulfur content in the diesel oil is 0.5%～1.0%), the diesel filter and the machine filter should be replaced every 150h; the diesel filter should be replaced every 60h if the sulfur content is above 1.0%. Filter, machine filter. Use crushers, vibratory rammers and other equipment that have a heavy load on the hydraulic system. The replacement time of the hydraulic return filter element, the pilot filter element and the respirator filter element is every 100h.
