The quality of HEDEC hydraulic filter element has a great impact on the working performance of the hydraulic system. Many faults are caused by it. To prevent oil pollution, install a hydraulic oil filter in an appropriate place, which can intercept the pollutants in the oil, keep the oil clean, and ensure the normal operation of the oil system. Hydraulic oil filter can be divided into surface type, depth type and magnetic filter according to the filter material. Their filtration of solid pollutants is accomplished through direct interception and adsorption.

The main function of HEDEC hydraulic filter element is to filter the hydraulic fluid, and various impurities inevitably appear in the hydraulic system. The main sources are: mechanical impurities that remain in the hydraulic system after cleaning, such as rust, casting sand, welding slag, iron filings, paint, paint and cotton yarn filings, and impurities that enter the hydraulic system from the outside, such as dust from the oil filler and dust ring; Impurities generated in the working process, such as fragments formed by hydraulic action of seals, metal powder generated by relative wear due to movement, colloid, asphaltene, carbon residue, etc. generated by oxidation and deterioration of oil.

The performance of HEDEC hydraulic filter element will be greatly affected in winter. With the change of temperature, the viscosity of ordinary lubricating oil will also deteriorate with the decrease of temperature, and the friction resistance of all parts in the engine will increase when moving, which will lead to the reduction of machine performance.

The use and maintenance in winter are different from those in other time periods, especially in the cold and foggy weather in the south. The maintenance of the filter element is more important. If the environment used is too dusty, the hydraulic oil filter element may store a lot of dust and dirt. It should be kept dry and ventilated. If necessary, the stainless steel filter element can be cleaned.

It is very important to increase the temperature and keep warm of the filter pipeline in the severe winter. The filtration can only be achieved by ensuring the fluidity of the fluid. Detect the differential pressure of the filter element in time to prevent the blockage of the filter element from causing pipeline damage. In short, in severe cold, filtration should be paid more attention.
