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.
