    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.

    Saintyol DAWIN Machinery shares the reason why the tunnel shotcrete is sprayed down?
    The general concrete spraying process is divided into dry spraying and wet spraying. For dry sprayers and small wet sprayers used for manual manual operation, the amount of rebound and drop of the spray is still very easy to control. If there is a large amount of falling, it is the problem of the ratio of sprayed concrete and the accelerator. For large wet spraying machines (manipulators), there are many reasons for falling sprayed concrete.

    Do you know how a concrete pump works?
    Most of the small concrete pumps are in the form of double cylinders. The two hydraulic cylinders drive the pistons of the two conveying cylinders to work alternately, which not only makes the conveying of concrete more stable and continuous, but also greatly increases the displacement. Its working principle varies according to the distribution valve and control method, but the main difference is still reflected in the realization of the reversing action.
