Piston rotor wet shotcrete machine is a rotor concrete wet shotcrete machine. It has high construction efficiency and greatly improves the construction operation environment. It is widely used in railway highway tunnels, water conservancy and hydropower, subway tunnels, mine roadways, military facilities, various underground buildings Engineering construction in areas such as emergency rescue.
Piston rotor type wet shotcrete machine has the characteristics of reasonable design structure, stable performance, convenient operation and maintenance, and long service life.
Working principle of piston rotor wet shotcrete machine
The piston rotor wet shotcrete machine is composed of main components such as feeding system, conveying system, air pipeline system, accelerating agent metering system, electrical control system, transmission system, walking system and so on. Working principle of rotor-piston wet shotcrete machine: The mixed finished concrete enters from the hopper of the wet spraying machine, and is evenly sent to the gas material mixing bin through the feeding system, and mixed with the high-pressure air in a thin flow state through the spray pipe to the nozzle; The flow rate of the metering pump is adjusted according to the content of the liquid accelerator. The pumped liquid accelerator is mixed with the high-pressure air through the atomizer. After the atomization, the nozzle mixing ring is mixed with the concrete in a thin flow state and sprayed from the nozzle. To the sprayed surface.
