How Does A Mixer Pump Work?

There are two steps in the working principle of cement mixer and pump: mix and convey.
Firstly, mix the concrete in the concrete mixer and after the mixing process, and pump the concrete mixture to the construction site through the pipeline. Here will be a detailed introduction about the pumping process. Concrete piston connected with main oil cylinder piston rod does reciprocating motion when pumping the concrete mixture, under the effect of hydraulic oil of main oil cylinder.

Secondly, When the piston goes forward, the other piston will retreat. And under the effect of swing oil cylinder, S distributing valve is connected with concrete and concrete cylinder is connected with hopper. In this way, when the piston retreats, the concrete will be inhaled into the concrete cylinder; when the piston goes forward, the concrete mixture will be delivered to the S distributing valve, and be pumped to the construction site and achieve continuous delivering.

In addition, there is a reverse state. And by the reverse pump operation, connect the concrete cylinder that stays in the inhaling process with S distributing valve, and connect the concrete cylinder that stays in pushing process with hopper, and withdraw the concrete of the pipeline to the hopper. The pumping system uses S distributing valve to complete the suction and discharge of the concrete.

Therefore, S distributing valve is the key part of the cement mixer with pump, and it will have a direct effect on the performance of the concrete pump.
