The main factors affecting the use time of hydraulic filter are:
1, hydraulic oil filter filter precision.
Filtration accuracy refers to the filtration ability of filter materials to filter pollutants of different sizes. It is generally believed that the filtration accuracy is high and the life of the filter element is short.
2, hydraulic oil filter amount of pollution.
Contaminant capacity refers to the weight of particle pollution that can be accommodated by the filter material per unit area when the pressure drop of the filter material reaches the specified quantity value during the test. The direct parameter reflection of the end of the life of the hydraulic oil filter element is that the pressure difference between the upstream and downstream of the filter element reaches the pressure of the bypass valve opening, and the pollution absorption capacity of the filter element also reaches a large value. If the pollution absorption capacity of the filter element is considered in the design and manufacture of the filter element, the life of the filter element is improved.
3, wave height, wave number and filtration area.
Under the premise that the external size of the hydraulic oil filter element has been determined, changing the wave height, wave number and other process parameters can increase the filter area as much as possible, which can reduce the flux on the surface of the unit filter material and increase the amount of pollution in the entire filter element, and improve the life of the filter element. By increasing the filter area of the filter element, the service life of the filter element tends to increase faster, if the wave number increases too much, the crowded folding wave will reduce the hydraulic oil flow space between the wave and the wave, making the filter pressure difference increase! The time to reach the filter pressure difference is short and the life is reduced. Generally, it is appropriate to keep the wave spacing at 1.5-2.5mm.
4, the strength of the hydraulic oil filter support network.
It is very important that the metal mesh of the inner and outer layers have a certain strength in the structure of the hydraulic oil filter, and the metal mesh maintains the corrugated shape to prevent bending and to support the filter material to prevent fatigue failure.
