Plasma Cutting Machine Use Environment Control

The use of CNC plasma cutting machine involves the energy of electricity, gas, etc., plus the dust formed during the material cutting process. It has certain requirements for environmental control. In the current domestic processing plant and environment, CNC The environmental control of the plasma cutting machine has a large gap in both awareness and hardware facilities. As a Plasma ARC Welding Torch Manufacturer, here we will give some thoughts and suggestions on the environmental control issues of the CNC plasma cutting machine.
Plasma cutting machine will produce noise, smoke, arc and metal vapor during the cutting process, which will cause environmental pollution, especially when cutting or cutting non-ferrous metals at high current. Several different equipments and techniques are available to reduce this level of contamination. In addition to water recompression plasma arc cutting, water surface cutting and subsurface cutting are also effective methods to suppress environmental pollution.
It is necessary to have a water storage tank for cutting on the water surface, and the work table for placing the workpiece in the water storage tank is composed of a plurality of arranged pointed steel members, and the pointed steel members support the cut workpiece on a horizontal surface. When the torch is working, the plasma arc is surrounded by a layer of water curtain. In order to maintain a continuous water curtain, a circulating water pump is required to pump water out of the water reservoir before entering the torch. When the water is sprayed from the cutting torch, a water curtain is formed around the plasma arc. This water curtain greatly controls the environmental damage caused by noise, smoke, arc and metal vapor generated during the cutting process. This method requires a water flow of 55 to 75 L/min.
Plasma Cutting Torch
Subsurface cutting is to place the workpiece about 75mm below the surface of the water. The table on which the workpiece is placed consists of a pointed steel member. The purpose of selecting a pointed steel member is to provide the cutting table with sufficient capacity to accommodate chips and slag.
When the torch is launched, the water around the nozzle end face of the torch is first discharged with a stable compressed air flow, and then the plasma arc is ignited for cutting. When cutting under the water surface, keep the depth of the workpiece submerged under the water surface. A system for controlling the water level should be prepared, and then a water pump and a water storage tank should be added to maintain the water level by means of water injection and drainage.
Generally, a manual plasma cutting machine cutting or automatic cutting work station should be equipped with an exhaust system to extract the exhaust gas from the work shop. However, the exhaust gas still pollutes the environment. If the pollution caused exceeds the national allowable standard, the smoke and dust transition equipment should be added.
