  • Saintyol DAWIN shares about the hydraulic system of fine stone concrete pump
    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.

    The operator of the concrete mixing pump should check whether the thickness of the brake pads of the braking system is too thin. If they are worn to a certain extent, they must be replaced. It should be noted that if the brake drum wears too much, even if the thickness of the brake pads is full, it may cause The brake camshaft travel is too long, causing the brake shoes to die. Also check to see if the brake camshaft grease passages are not blocked.

    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.

    Precautions for pump operation:
    1. The place where the pump truck is in place is flat and solid, and there are no obstacles around. Pump trucks must not be parked on slopes. The parking position meets the needs of pouring, and does not obstruct each other with other on-site machinery, which affects the construction progress and the safety of construction workers.

  • Do you know the characteristics of the fine stone concrete pump in the process of concrete conveying on the floor
    Do you know the characteristics of the fine stone concrete pump in the process of concrete conveying on the floor
    The fine stone concrete pump adopts a hydraulic system. The concrete pump has the characteristics of long concrete cylinder stroke, high vertical distance for conveying concrete, and long distance for horizontal conveying concrete. The fine stone concrete delivery pump, ground pump and drag pump all adopt a continuous lubrication system, which solves the damage to the fine stone concrete pump due to lack of lubrication during the process of conveying concrete.
