Main performance index of the oil suction filter
1. The filtration precision
Filtration precision refers to oil suction filter filter ability of different size particles of pollutants, commonly used absolute filtration precision, filter ratio and efficiency indicators to assess, such as filtering precision can be divided into coarse acuity 0.1 mm (d), the common acuity 0.01 mm (d), acuity 0.005 mm (d), and pure acuity 0.001 mm (d) four levels.

2. The pressure drop characteristics
Oil filter for oil in the hydraulic system is a kind of fluid resistance, thus the oil passes are bound to produce pressure drop. In general, under the condition of the filter size and oil flow must, filter filtration precision is higher, its pressure drop is larger, the flow of certain cases, the core of effective filter area, the greater the or the oil viscosity is smaller, the smaller the pressure drop.
Filter the maximum allowable pressure drop, should be to make the filter does not occur structural damage for the principle. Usually, aviation and the initial pressure drop ship with oil suction filter should not be more than 0.25 MPa; Machinery with oil suction filter pressure drop is not greater than 0.08 MPa to 0.15 MPa.
3. The capacity of nurgle
Oil suction filter in the pressure drop is greater than the limit, the issue of intercept pollutants before called the pollutant carrying capacity, expressed as a weight (g). Oil suction filter nurgle capacity is larger, the longer its longevity, so it is an important index of oil suction filter life. Effective filter area, the greater the oil suction filter is nurgle capacity.
