What is the working principle of concrete pump?

Concrete pump, also known as concrete pump, mainly by the pump and the pipe two parts, is now widely used in construction, bridges and tunnel construction. What is the working principle of concrete pump? Concrete pump mainly uses motor or diesel-driven pumping system, through hydraulic system constant power control to automatically adjust the delivery volume of concrete pump, can also be manually controlled to select the amount of concrete delivery. The pumping system is mainly composed of hopper, stirring mechanism, concrete distribution valve, concrete conveying cylinder, washing chamber and main oil cylinder. The specific working principle is that when the hydraulic system pressure oil into a main cylinder, the piston rod extended at the same time through the sealing circuit connecting the pressure of the oil to the other piston rod retraction. The concrete conveying piston connected with the piston rod of the main oil cylinder is self-priming in the conveying cylinder when it is retracted. The concrete in the hopper is sucked into the conveying cylinder through the suction port of the sliding valve under the action of atmospheric pressure and stirring blades. At the same time, the other main oil cylinder under the action of the hydraulic pressure pushes the piston rod of the main oil cylinder and at the same time pushes the concrete piston out of the concrete in the conveying cylinder and enters the concrete conveying pipe through the Y-pipe of the sliding valve delivery port. After the action is completed, the system automatically commutates the pressure oil into another master cylinder to complete the suction and delivery of another different delivery cylinder. So repeatedly, the hopper of concrete on a steady stream of being sucked into and out of the pressure delivery cylinder, through the Y-tube and outlet pipe connected to the arrival point to complete the pumping operation. The above is the general working principle of concrete pump, I hope for your understanding of the help. Industry Internet (Xiamen) Technology Co., Ltd.
