The portable concrete pump for sale stands for concrete pump with boom, which is movable on trucks. The most important structural part of the portable concrete pump truck is of course its boom, which supports the distribution pump pipe of the whole truck, and the multi-section boom design makes concrete pouring more flexible and convenient. To drive the action of the boom, it is necessary to rely on the movement of the boom cylinder. Each boom is like the joints of the human body, and to make the corresponding movements between the joints, it needs to rely on the muscles on the human body. The boom cylinder is the "muscle" of the portable concrete pump truck.

As the boom of the portable concrete pump for sale becomes longer and longer, the pressure of the boom cylinder needs to be increased. As the core component of the boom hydraulic system, what is the working principle of the boom cylinder of the concrete pump truck? Why can it withstand so much pressure? Today we will talk about this issue.

The pressure oil of the portable concrete pump for sale comes from an inclined-axis axial quantitative pump. The control of the boom cylinder and the electronic control speed adjustment are realized through the boom multi-way valve, so that the boom can work according to the operation instructions issued by the operator, and realize the precise control of the boom cylinder. The pressure on the boom cylinder is proportional to its load. The greater the load, the higher the oil pressure of the cylinder. With the length of the boom and the filling of the pump pipe with concrete, the boom cylinder will inevitably be affected. The pressure is getting higher and higher, and the key to keep the hydraulic oil rod at a higher pressure is the sealing performance of the sealing ring in the oil cylinder. The pressure oil in the cavity will not leak out, so that the boom cylinder will not slip.
