1. Working principle and structure of concrete pump truck
Concrete pump truck is a machine that uses pressure to continuously transport concrete along pipelines. An electronic control system is installed on the truck. , boom system, pumping system and hydraulic system to transport concrete to a certain height or distance. The structural principle of the concrete pump truck is:
1. Electronic control system: It consists of a remote control, a sensor and an operating box. It transmits operating instructions to each component of the concrete pump truck through power supply.
2. Boom system: It consists of a distribution boom and a turret. It mainly supports the entire vehicle, completes the transportation of concrete, and ensures its stability during the transportation process. The boom pump truck uses a boom system. If it is a ground pump truck, it needs to be transported by laying special pump pipes.
3. Pumping system: It consists of a pumping mechanism, a hopper, and a lubrication mechanism. It is the actuator of the concrete pump truck and can continuously transport concrete along the pipeline to the pouring site.
4. Hydraulic system: It consists of an oil pump, a fuel tank, a boom pump, etc. It mainly achieves energy conversion and increases force by changing pressure.
When the pump truck operator presses the remote control, the concrete pumping work starts and can be stopped after the pumping is completed.
2. What are the characteristics of concrete pump trucks
Concrete pump trucks are indispensable engineering machinery for concrete operations. They have the following characteristics:
1 , Safe and reliable: the main structure is made of imported high-strength steel plates, and the boom adopts vibration reduction technology, protected unilateral operation holding technology, anti-tilt control technology, flexible reversing technology, and patented electro-hydraulic proportional displacement multi-level control. technology, etc., providing all-round, high-standard safety and reliability.
2. High pumping efficiency: The concrete pump truck adopts ultra-large displacement pumping technology, which can significantly reduce the pumping frequency, improve the suction efficiency, and reduce the loss of related components.
3. Easy operation and maintenance: The concrete pump truck adopts technologies such as automatic piston retraction, automatic reverse stirring, and easy disassembly and assembly of the intermediate ring and piston rod. It is easy to operate and can significantly reduce maintenance costs.
4. Energy saving and environmental protection: The concrete pump truck’s engine intelligent energy-saving technology can save fuel.
5. Stability: Highly configured hydraulic systems such as imported pumps and motors ensure the stability and reliability of the hydraulic system.
6. Long service life: The delivery pipe, reducing pipe, spectacle plate cutting ring, etc. are all made of highly wear-resistant materials, extending the service life of wearing parts.
