Diaphragm pump cold spray marking machine is a commonly used equipment for drawing road markings, which usually consists of diaphragm pump, pneumatic control system, and spraying head. Its working principle is as follows:
Diaphragm pump: The diaphragm pump is a key component that pumps paint from the storage tank to the spray head. The diaphragm pump generates negative pressure by driving the diaphragm with compressed air, extracts the coating, and delivers it to the spraying head.
Pneumatic control system: The pneumatic control system is mainly responsible for controlling the working rhythm of the diaphragm pump and regulating the pressure during the spraying process. By controlling the switch of the pneumatic valve and feedback from the pressure sensor, it is ensured that the coating can flow evenly and maintain a stable spraying effect.
Spray head: The spray head is a component used for spraying paint after it is conveyed from the diaphragm pump. The spraying head usually includes a nozzle and an atomizer. The nozzle is responsible for evenly spraying the paint on the road surface, while the atomizer can atomize the paint into small particles, making the spraying more uniform.
Overall, the working principle of the diaphragm pump cold spray marking machine is to draw paint from the storage tank and transport it to the spraying head through the diaphragm pump. Under the adjustment of the pneumatic control system, the paint is evenly sprayed on the road surface through the spraying head, thus completing the drawing work of road markings.
