With the increasing requirements for project quality, progress and environmental protection, more and more anchor spraying support projects use hydraulic wet spraying machines. The working principle of the hydraulic wet spraying machine is to use the thrust generated by the hydraulic pump to make the two oil cylinders move back and forth alternately, and send the dense flow material from the conveying pipeline to the mixing pipe, and form a thin flow through the compressed air and send it to the nozzle through the pipeline. Liquid accelerator is added at the nozzle and directly sprayed onto the sprayed surface. It is a kind of mechanical, electrical and hydraulic three-in-one mechanical equipment.

The hydraulic wet spraying machine is a pump-type concrete wet spraying machine. It adopts hydraulic pumping, with high system reliability and stable delivery volume. The hydraulic wet spraying machine can be used for spraying, filling, grouting, pumping and other construction. The injection amount is continuously adjusted: the main oil pump adopts a variable plunger pump, and the injection speed can be freely adjusted. The amount of accelerator added is continuously adjustable: it can be adjusted steplessly according to the amount of spraying.

The hydraulic wet spraying machine adopts a four-wheel solid tire design, which is easy to move and has multiple uses. It can be used as a wet spraying machine, as well as a concrete delivery pump or mortar pump. It is widely used in concrete spraying construction operations in mines, tunnels, culverts, subways, hydropower projects, construction foundation pits, underground projects and slope protection.
