A concrete pump truck is a device that is specifically used to transport concrete from a mixing station to a job site. The working principle of the hydraulic system is mainly that the hydraulic system is used for pumping concrete to a required position.
Specifically, the concrete pump truck consists of a concrete conveying pipeline, a hydraulic system and a driving device. When the pump truck arrives at the construction site, the legs of the pump truck will be deployed to remain stable. The concrete mixer truck pours concrete into the hopper of the pump truck.
The hydraulic system then starts to operate, pushing the concrete into the delivery line by means of the hydraulic pump. The hydraulic system controls the flow of concrete through a series of pistons and valves, pushing the concrete from the hopper into the pumping tubes.
The drive means of the pump truck (typically a diesel engine) powers the hydraulic system, ensuring that the pumped concrete reaches the target location with sufficient pressure and flow.
In general, concrete pump trucks utilize hydraulic systems to push concrete from a hopper into a delivery line and use drive equipment to provide power to perform the function of pumping the concrete. This principle of operation allows the concrete to be quickly and efficiently transported from the mixing station to the desired construction site.
Concrete pumps mainly utilize the principles of hydraulic systems and piston pumps to convey concrete.
Specifically, the hydraulic system pressure-converts the hydraulic oil in the hydraulic cylinder by a hydraulic pump. The hydraulic pump draws in oil and pumps it by pressure into the hydraulic cylinder, causing the oil to create a high pressure in the hydraulic cylinder. This high pressure oil will push the piston back and forth in the oil cylinder.
The piston pump in the concrete pump truck is a piston pump capable of repeatedly reciprocating, and high-pressure oil is pushed to a target position of concrete through a conveying pipeline by the reciprocating motion of a piston. The follow-up valve in the piston pump can control the flow of oil in the inlet and the outlet according to the movement direction of the piston.
During transport, the piston moves backwards as concrete is sucked into the cylinder of the piston pump. And during pumping, the piston moves forward, pushing out the concrete. In this way, concrete can be continuously transported by the continuous reciprocating motion.
In general, concrete pump trucks utilize the principles of hydraulic systems and piston pumps to transport concrete from a mixing plant to a job site through constant reciprocation and pressure conversion.
The impact force is directly received by the buffer part 4 when the concrete is discharged from the pump tube 1.
The insert rod 602 is pulled out, so that the rotating block 601 can be rotated out of the block 603, and the bracket 3 can rotate around the rotating shaft 5 as a circle center. So that the buffer 4 is removed from the sleeve 2.
