The filtration degree of stainless steel fabric mesh can be divided into: nominal filtration degree and absolute filtration. Actually filtered. Absolute filtering you may not be familiar with, in fact

Absolute filtration degree (also called absolute aperture): refers to the cross section of the twill weave dense mesh, the maximum inscribed circle diameter of the inclined surface of the adjacent two weft wires and the warp wire forming the triangular hole.

The actual filtration degree of stainless steel fabric mesh refers to the filtration degree of dense mesh under actual use conditions. For a specific size of the dense stainless steel filter, the actual filtration degree of the same size of the dense stainless steel wire mesh changes accordingly when the conditions of use change. The actual filtration degree of the dense mesh is directly affected by the use conditions 

such as temperature, differential pressure, length of use, viscosity of the medium, and bending times of the filter holes. Therefore, the actual filtration degree is a variable value.

When the stainless steel fabric mesh is used for a long time, it is inevitable that the screen is damaged. Hebei Mashi Wire Mesh Co., Ltd. solves the problem for you:

1Replace the mesh number of the screen or adjust the flow rate of the single screen to ensure that the flow stop point of the drilling fluid is close to the screen outlet, so that the drill cuttings can be smoothly discharged under the lubrication of the drilling fluid.

2 increase can increase the vibration amplitude.

3. The angle of the screen at the end of the sand discharge can be downwards. In this way, the cuttings can be discharged by gravity, and there is also a problem that there may be running water.

4. Spray must be used when sifting the screen and cuttings, so that the viscosity of the cuttings can be reduced.
