Building concrete pump is how to bulk cement (concrete) to the high
After the action is completed, the system automatically change the pressure oil into another main cylinder, to complete another different delivery tank suction, send travel.
At the same time, another main cylinder under the action of the pressure, to promote the main cylinder of the piston rod out and at the same time to push the concrete piston out of the concrete tank, through the slide valve Y port into the concrete pipe.
The concrete conveying piston connected to the main cylinder piston rod is self-priming in the conveying cylinder. The concrete in the hopper is sucked into the conveying cylinder through the suction port of the valve under the action of the atmospheric pressure and the stirring of the stirring blade.
When the hydraulic system pressure oil enters a main cylinder, the piston rod is extended and the other piston rod is retracted by the pressure oil of the sealing circuit connecting the pipe.
Repeatedly, the concrete in the hopper is continuously sucked in and out of the delivery tank, through the Y-pipe and outlet connected to the pipeline to reach the point of operation to complete the pumping operation
