Road marking machine with piston pump

GD18L-II road marking machine with piston pump is production of road marking construction of special machinery. Using hydraulic transmission as a power-driven and make paint pump work. Adopting compress paint producing high pressure, and then make paint atomization in the gun, spraying out from spray nozzle.

In order to make pressure stable, GD18L-II road marking machine adopts the method of controlling the working pressure of the hydraulic cylinder. It could achieve the goal of controlling the working pressure of the high-pressure piston pump in a proportional manner. The advantage is that the working pressure of the oil pump is low and the control is convenient. As the high-pressure paint does not overflow, it will not warm the paint, paint the viscosity is relatively stable, which is of great significance to improve the quality of marking.
