The working principle of remote control double cylinder double bridge mobile sandblasting machine

Remote control type double cylinder double gunMobile sandblasting machineEach gun is equipped with a three-position remote control switch, which can separately control air jet, sandblasting and stop working. The upper and lower silos are equipped with sensor switch level meters, which send signals to solenoid valves, and indirectly control the internal closed valve cylinder and the air-controlled ball valves for intake and exhaust through the air circuit. Together with the time relay, the sanding and Put sand. When the remote-controlled dual-cylinder dual-gun mobile sandblasting machine starts sandblasting, the lower silo closing valve cylinder is closed, and the upper silo closing valve cylinder opens to start sand filling; when the upper silo is full, the upper silo level indicator A signal will be sent to close the upper silo closing valve cylinder to stop adding sand; when there is no sand in the lower silo, the lower silo level indicator will send a signal, the lower silo closing valve cylinder is open, and the upper silo closing valve is closed at this time , The sand in the upper silo will fall into the lower silo; the time for adding sand in the lower silo is set by the time relay. When the time is up, a signal is sent to close the cylinder of the lower silo closing valve, and the upper silo closing valve is opened to add sand to the upper silo. In, the sandblasting operation of the remote-controlled dual-cylinder dual-gun mobile sandblasting machine does not need to be stopped.

A small air bag is installed next to each group of sand blasting cylinders of the remote-controlled dual-cylinder double-gun mobile sandblasting machine to ensure that there is enough compressed air. The small air bag is located on the compressed air line and above the abrasive valve. A ball valve ensures that when repairing different parts, it does not affect the normal operation of the other road. Adjusting the tight opening and closing of the ball valve and the abrasive valve can control the flow of air and abrasive to meet the requirements of different workpieces on the sandblasting process. The steel shot and steel grit used by the remote-controlled dual-cylinder dual-gun mobile sandblasting machine can be recycled repeatedly.
