Concrete mixer control system tips

The rotation speed of the mixing drum concrete mixer control system and a concrete mixer concrete pump agitation to reduce the volatility of the mixing tube rotation speed, thereby improving the quality of the concrete mixing.

In the concrete mixing machine production process, in order to achieve mixing drum rotational speed control system, including the variable displacement pump is used to drive the stirring cylinder movement requirements of the hydraulic motor and the drain quantity control unit, the hydraulic motor and variable displacement pump through oil path the connection with the speed set on the oil passage regulating hydraulic motor valves, inlet and outlet, respectively, and the variable pump connected to the outlet and being connected to said intake port.

For the concrete mixer in production, the speed of the speed adjusting valve inlet and outlet valve, a drain oil passage by the amount of the amount of the drain are connected to the control unit and the control unit is connected, the speed control valve is capable of inlet and outlet pressure difference is greater than the first preset value, which controls the variable displacement pump, the amount is reduced.

In the differential pressure signal control and drive technology plan concrete mixer main oil control valve for regulating the export variable discharge pump, so that the rotational speed of the mixing tube is a fast sampling rate to reduce the speed of agitation of the mixing tube the rotational speed of the cylinder is greater than a predetermined value to reduce the speed of rotation speed of the mixing tube.
