3. flame profile is easily influenced by flow of external air, aligned environment requires height, operating personnel that can not use air-conditioning, electricity
Fan etc.;
4. existing welding gun rifle core because the volatilization of scaling powder easy tos produce clogging, need to regularly replace rifle in production
Core.
The technology of the hybrid two stations solderer use in industry is at present:Respectively by adjusting combustion gas and air (oxygen
Gas) flow, mix using gun barrel after so that combustion gas and air is formed certain proportion, finally lighted in muzzle.
The defect and deficiency of two station solderer of conventional hybrid formula:
1. air and combustion gas are required to be conveyed in the case where there is pressure, to the stabilization of air pressure and gaseous-pressure
Property require it is higher, if pressure has fluctuation that will directly affect the stability of flame.
2. Gas Pipe route does not have check-valves, there is the risk that flame reflux gas explosion occurs.
3. pipeline is more complex, every welding gun to be both needed to a set of regulating valve is separately configured, inconvenience is unified to be adjusted.
4. since equipment pipeline is more complex, every solderer can only generally configure 4 welding guns, influence to be brazed improved efficiency.
