Description

Technical Field

[0001] The invention relates to the field of ultrafiltration filter elements, and in particular to an ultrafiltration filter element with good filtering effect and a filtering method. Background Art

[0002] 70% of hydraulic system failures are caused by particle contamination of hydraulic oil. Particle contamination will increase hydraulic system wear and cause pollutants to increase exponentially, forming a vicious cycle. It is the main source of hydraulic system failures. Traditional filtration methods are mostly surface filtration or depth filtration. The filter medium of surface filtration acts as a surface to intercept dirt when working, so as to achieve the purpose of purifying and separating the working medium. In depth filtration, there are a large number of semi-through holes and through holes inside. Some dirt particles are blocked on the surface near the upstream of the medium, and some smaller particles enter the filter medium and are adsorbed on the hole wall under the action of contraction, expansion, hydraulic effect, etc. However, the most practical way now is to use ultrafiltration, and in the ultrafiltration process, it is often necessary to use ultrafiltration filter elements to filter the hydraulic oil.
