Q:How does a concrete pump piston work?

A concrete pump piston works by creating a reciprocating motion that pushes the concrete through the pump and into the desired location. The piston is a cylindrical component that fits snugly inside a cylinder. It is connected to a rod, which is attached to a hydraulic system. When the hydraulic system is activated, it pushes the rod forward, causing the piston to move in the same direction. As the piston moves forward, it creates a vacuum behind it, drawing the concrete into the cylinder through an inlet valve. Once the piston reaches the end of its forward stroke, the hydraulic system reverses its direction, pulling the rod back and causing the piston to move backward. This closes the inlet valve and opens an outlet valve, allowing the concrete to be forced out of the cylinder and into the delivery line. The reciprocating motion of the piston, along with the alternating opening and closing of the inlet and outlet valves, allows for a continuous flow of concrete through the pump. This process is repeated rapidly, allowing for efficient and consistent pumping of concrete to the desired location.

Q:How long does it take to receive concrete pump spare parts after placing an order?
