The steel wire mesh is made of metal wire mesh of different meshes. Its function is to filter the molten material flow, increase the flow resistance, thereby filter out the mechanical impurities, and improve the mixing or plasticizing effect. Why is the wire mesh damaged? The steel wire mesh is mainly made by connecting metal meshes with different meshes and supporting meshes and through the hemming process. It is used for screening and filtering under acidic and alkaline environmental conditions.

It is used as a mud net in the petroleum industry and as a screen in the chemical and chemical fiber industries. Strainer, pickling screen for electroplating industry. The main causes of rapid damage are clay accumulation, wrong direction of electrical composition, poor fit between screen and screen frame, and poor screen quality. When the vibration amplitude of the clay accumulation is too small.

It is difficult to screen under the condition of polymer drilling fluid, and the viscous force of drill cuttings cannot be overcome, resulting in the accumulation of drill cuttings on the screen and rapid damage. screen. Change the screen mesh or adjust the flow rate of a single screen. The stop point of the drilling fluid is close to the outlet of the screen, so it is under the lubrication of the drilling fluid.

Drilling cuttings can be discharged smoothly. Adjust the angle of the screen at the end of the sand outlet downwards, which will help to discharge rock debris by gravity, but may cause mud loss. Use water spray to flush the screen and drill cuttings to reduce the viscosity of the drill cuttings. Increase the vibration amplitude. The above methods can solve the damage of the steel mesh.
