The working principle of the pump truck when pumping concrete
Working principle of concrete pump Concrete pump (support pump) is composed of hopper, pump body, hydraulic cylinder for driving slide valve, slide valve, conveying cylinder, main hydraulic cylinder and pilot valve. When the main hydraulic pump drives the concrete piston to retract, under the push of the mixing blade, the concrete poured into the hopper is sucked into the delivery cylinder through the suction port of the slide valve. When the main hydraulic cylinder moves forward, the concrete delivery cylinder piston is pushed forward, through the slide valve The valve feeds into the Y-piece. Since there are two sets of main hydraulic cylinders, conveying cylinders, and slide valves, which work alternately on the left and right, the continuous conveying of concrete is realized.
Concrete is delivered to upper floors. Concrete pump operating procedures 1. Before operation, check and confirm that the bolts of each part of the pump are fastened, the protective devices are complete and reliable, the control switches, adjustment handles, handwheels, control rods, cocks, etc. of each part are in the correct position, and the hydraulic system is normal without leakage. , the hydraulic oil meets the regulations, and there is no debris in the mixing bucket. The protective grid above is intact and tightly covered.
