CNC flame cutting machine automatic ignition device consists of a lighter, ignition cable gas hose and fixed frame, one end of the ignition cable is connected to the lighter, and the other end is connected to the ignition controller. One end of the gas hose is connected to the ignition gun, and the other end is connected to the gas source. The on and off of the gas is controlled by the solenoid valve, and the fixing frame fixes the ignition gun on the single torch. The ignition process is controlled by the ignition button on the console. When the ignition button is depressed, the gun is ignited to ignite the torch. The auto-ignition gun passes through the gas and does not need to pass oxygen. The oxygen required for combustion of the gas comes from the air. When the gas of the numerically controlled flame cutting machine enters the injecting nozzle of the igniter, the injection path is drastically reduced, so that the flow rate of the gas enters the igniter. When the internal space increases dramatically, a negative pressure is generated inside the lighter to allow outside air to be drawn into the lighter from the small hole to provide combustion oxygen. When the mixed gas formed of gas and air is ejected from the igniter, it is ignited by the high-voltage arc supplied by the ignition controller, thereby igniting the torch. In order to prevent the NC flame cutting machine ignition gun from being contaminated in the flame cutting process, the distance between the end of the igniter nozzle and the torch cutting nozzle part must not be less than 150mm to ensure reliable performance of the ignition gun. The joint between the gun injection nozzle and the end of the squib must be tightly sealed to prevent excessive air from entering the igniter and affect the ignition performance. The injection nozzle must be kept clean to ensure the gas flow freely. In case of blockage, blow with compressed air. Pass, pay attention not to use hard objects such as drills to prevent damage to the gun. The connection cable between the ignition cable and the ignition gun of the CNC flame cutting machine is connected with the ignition gun with a nut. The cable end is flush with the compression nut. When the ignition gun is used for too many times, the end of the cable that contacts the gun will be burned out. Ignition performance. In this case, press the nut tightly and use a pair of scissors to cut out the burned cable. Care must be taken when cutting. The shear must be flat and the cable must be installed to restore the ignition performance. Chinese cutting machine trading network, allowing you to buy the rest assured!
