    Saintyol DAWIN shares about the hydraulic system of fine stone concrete pump
    Most of the fine stone concrete pumps use a hydraulic system. The piston rod in the main oil cylinder generates mechanical pressure under the power. When the piston retracts, it generates self-priming in the conveying cylinder. The concrete in the hopper is under the action of atmospheric pressure and the boost of the stirring blade. Under the action, it is sucked into the conveying cylinder through the suction port of the slide valve.
