The spray machine is suitable for the field of spraying technology. It consists of a black material tank and a white material tank. The tank body is a double-layer structure, and the intermediate layer is filled with constant temperature oil. It is equipped with electronic pressure sensors, mechanical pressure gauges, safety valves and other components. The bottom is equipped with a feeding pipe and a discharge pipe, and a diaphragm pump, plate heat exchanger, metering pump, flow meter and other equipment are installed. The hydraulic plate reversing valve is connected to the gun head. The innovation is to solve the problems of unstable pressure, unstable temperature and the inability to automatically fill materials in traditional spray machines.
