Concrete wet spraying machine plays an indispensable role in modern construction and tunnel construction. It can effectively improve construction efficiency and ensure the quality of shotcrete. In the large family of wet spraying machines, hydraulic wet spraying machine and rotor wet spraying machine are two common and important types. They have their own characteristics and are suitable for different construction scenarios. Let's talk about the difference between hydraulic wet spraying machine and rotor wet spraying machine.

　　Hydraulic wet spraying machine: a synonym for high efficiency and precision

　　Hydraulic wet spraying machine, as a high-end equipment integrating mechanical, electrical and hydraulic, adopts hydraulic pumping method. Its core advantage lies in the precise controllability of the amount of sprayed concrete and the amount of accelerated setting agent added. When working, the high pressure generated by the pumping system pushes the dense flow material to the mixing pipe, meets the compressed air to form a thin flow, and then is transported to the nozzle through the pipeline. At the nozzle, the accelerated setting agent is added according to the preset proportion and sprayed directly onto the sprayed surface. This design ensures the uniformity and rapid setting effect of shotcrete, and improves construction efficiency and concrete quality.

　　Rotor-type wet spraying machine: strong adaptability and economical

　　The rotor-type wet spraying machine stands out with its unique rotor piston cam feeding mechanism. The three material chambers are fed synchronously to ensure the uniform thin flow of plastic concrete in the pipeline. In the work process, the commercial concrete is sent to the air-material mixing bin through the feeding system, mixed with high-pressure air to form a thin flow, and then sent to the nozzle through the injection pipe. The liquid accelerator is mixed with the high-pressure air through the atomizer, and after atomization, it meets the concrete at the mixing ring of the nozzle and is finally sprayed onto the sprayed surface. This design makes the rotor-type wet spraying machine highly adaptable to different materials, but during the construction process, the replacement cycle of wearing parts becomes part of its use cost.

　　What is the difference between hydraulic wet spraying machine and rotor wet spraying machine?

　　Comparison between hydraulic wet spraying machine and rotor wet spraying machine:

　　1. Material adaptability: The rotor-type wet spraying machine has stronger adaptability to materials, while the hydraulic wet spraying machine has higher requirements for the quality of concrete.

　　2. Wearing parts and maintenance costs: The replacement of wearing parts of the rotor wet spraying machine is inevitable during use, while the hydraulic wet spraying machine is more economical in this regard.

　　3. Work efficiency and price: The hydraulic wet spraying machine is slightly better in work efficiency, which is one of the reasons for its relatively high price.

　　To sum up, the hydraulic wet spraying machine and the rotor wet spraying machine have their own advantages. The choice of which type of wet spraying machine should be based on the specific construction needs, material characteristics and cost budget. While pursuing efficiency and quality, rationally allocate resources to achieve the best construction effect.
