รายละเอียดสินค้า

The S-tube rocker arm in the concrete pumps manufactured by Zoomlion Heavy Industry and Sany Heavy Industry serves an essential function in the pumping process.

The primary role of the S-tube rocker arm is to control the flow of concrete within the pumping system. It consists of a curved, S-shaped tube that acts as a valve, alternating between the intake and discharge phases of the concrete pump.

During the intake phase, the S-tube rocker arm positions the S-tube in a way that allows it to draw concrete from the hopper or receiving hopper. This ensures a smooth and continuous flow of concrete into the pumping system.

In the discharge phase, the S-tube rocker arm shifts the S-tube's position, closing the intake side and opening the discharge side. This directs the concrete under pressure from the pumping cylinders towards the outlet pipe or delivery line, allowing for precise placement or transfer of the concrete to the desired location.

The S-tube rocker arm's movement is synchronized with the operation of the pumping cylinders, ensuring efficient and controlled pumping of concrete. It works in conjunction with other components, such as the hydraulic system, to coordinate the timing and flow of concrete throughout the pumping process.

The S-tube rocker arm's design and construction are crucial to withstand the high pressures and abrasive nature of the concrete being pumped. It is typically made of durable materials and undergoes rigorous testing to ensure its reliability and longevity.
