What is the working principle of the engine of a pump truck? What are the uses?

The function of a pump truck engine is to convert the thermal energy generated by the combustion of fuel in the cylinder into mechanical energy and output power externally. The energy conversion process is achieved by continuously repeating four continuous processes of "intake compression work exhaust". Each process of converting thermal energy into mechanical energy in the engine cylinder is called a working cycle.

In a working cycle, the crankshaft rotates two times and the piston reciprocates four strokes, which is called a four stroke engine.

Concrete pump truck is a mechanical device that uses pressure to continuously transport concrete along pipelines. Composed of pump body and delivery pipe. It can be divided into piston type, extrusion type, and water pressure diaphragm type according to its structural form. The pump body is installed on the chassis of the car, and then equipped with retractable or folding fabric rods to form a pump truck. The concrete pump truck is modified from the chassis of a heavy-duty truck. It is equipped with motion and power transmission devices, pumping and mixing devices, fabric distribution devices, and other auxiliary devices on the chassis. The power of the concrete pump truck is transmitted to the hydraulic pump unit or rear axle through the power transfer box, and the hydraulic pump pushes the piston to drive the concrete pump to work. Then, use the distribution rod and delivery pipe on the pump truck to transport the concrete to a certain height and distance.

The pump truck delivery end pipe, also known as concrete wear-resistant rubber hose, ultra-high wear-resistant rubber hose, has many direct sales of concrete wear-resistant rubber hoses in China. The rubber conveying series hose at the end of the concrete pump truck is suitable for connecting the end of the construction machinery pump truck during concrete conveying, and can flexibly change the pouring position for small-scale concrete paving.
