Lubricating oil filter element HC8904 series

Product introduction

The lubricating oil filter element HC8904 series is composed of shell, multi-element filter element, backwashing organization, and differential pressure controller. The diaphragm in the shell divides its inner cavity into upper and lower cavities, and the upper cavity is equipped with multiple filter elements, which makes full use of the filter space and significantly reduces the volume of the filter. Rinse the suction cups. It is mainly used for the filtration of the hydraulic system of rolling mills and continuous casting machines and the filtration of various lubricating equipment.

The technical process of the filter element

1. The filter material is made of fiber and resin. With a fixed void structure, the filter material does not fall off. The trapped contaminant particles do not "discharge" due to pressure differential and flow pulsation.

2. Adopt a gradual aperture structure that gradually narrows from the surface to the inside and along the flow direction. Layered retention of contaminant particles of different sizes. Thereby greatly improving the service life.

3. The spiral winding belt is used to strengthen the support to ensure the stability of the filter material.

Product Usage

1. The filter element should be installed at the suction port of the pump:

Generally, a surface oil filter is installed on the suction road of the pump to filter out large impurity particles to protect the hydraulic pump. In addition, the filtering capacity of the oil filter should be more than twice the flow rate of the pump, and the pressure loss should be less than 0.02MPa.

2. The filter element is installed on the outlet oil road of the pump:

The purpose of installing the oil filter here is to filter out the contaminants that may invade the valve and other components. Its filtration precision should be 10 ~ 15μm, and it can withstand the working pressure and impact pressure on the oil circuit, and the pressure drop should be less than 0.35MPa.

3. The filter element is installed on the oil return road of the system: this installation acts as an indirect filter. Generally, a back pressure valve is installed in parallel with the filter. When the filter is blocked and reaches the corresponding pressure value, the back pressure valve opens.

4. The filter element is installed on the branch oil circuit of the system.

5. The filter element separate filtration system: a large hydraulic system can be specially equipped with a filtration circuit composed of a hydraulic pump and an oil filter.
