At present, the flame cutting machine using straight strip cutting can be equipped with more than 10 strip torches. In order to ensure the stability of any single torch in the cutting process, it is necessary to increase the gas busbar device as an auxiliary. Therefore, when the CNC flame cutting machine is processed by the multi-strip torch cutting method, it is necessary to ensure the gas pressure and the air supply air velocity to achieve the final cutting effect. 
Thorough derusting must be stopped before the assembly of the busbars, oxygen busbars and pipelines. The outer wall of the tube is first coated with anti-rust paint and then coated with yellow alkyd paint. After the pipeline is connected, it is necessary to suspend the water pressure test of 8-10 atmospheres or suspend the airtightness test of 8-10 atmospheres. There are no burrs, rust spots, scales and other debris in the tube. Check for welds and joints for leaks. Be sure to install a static-dissipating grounding device on the busbars and acetylene piping.
According to the different types of cylinder switching between the left and right groups, it can be divided into manual switching, pneumatic (semi-automatic) switching and automatic switching. According to the needs of use, it can be equipped with gas heater, tempering preventer, pressure relief valve, gas leakage alarm, pressure alarm, pressure switch, bottle holder and other products to expand the function of gas bus in practical applications. To meet the needs of customers for high performance products. The common gas busbar is a system equipment that combines several gas cylinders into small groups and then decompresses them, and then transports them to the use terminal through the main pipeline, mainly for small and medium gas supply stations and other applicable places.
