Product description
Diesel concrete pump is a main kind of construction machinery in the course of commercial concrete transportation and deposition. It is motivated by diesel engine. By using it, concrete can be piped along the pipe to the pouring site. It consists of pumping body and conveying pipes. The diesel engine concrete pump usually appears in the construction of high buildings, bridges, high speed, tunnels and water conservancy projects, etc. Especially in some work only pumping function is not enough, our diesel concrete mixer pump is a great choice.
Diesel-powered stationary concrete pump adopts diesel engine to pump concrete, which is very fuel efficient. We mainly have DHBT Series diesel concrete trailer pump , these pump machines are much more suitable for areas lacking electricity or no electricity. Our company based on the mature hydraulic concrete delivery pump, developed the small and medium concrete pump that both pumping fine-stone concrete and mortar and pumping large aggregates. Main production throughput 20-40m ³/h, concrete conveying pressure is 3-13Mpa all kinds of motor concrete pumps. Suitable for industry and civil construction, transportation, railways, as well as concrete projects of water conservancy, electric power and other industries the economical, efficient delivery of concrete or mortar.

Main Systems and Working Principle
Concrete pump with diesel engine includes mechanical system, cooling system, lubrication system and so on.
1.The mechanical system consists of pumping system, main power system, hydraulic oil tank, chassis frame body, the axle and guide wheels.
2.Our cooling system adopts wind cooling system, including water tank, hydraulic motor, fan and the hose. Its function is to adjust hydraulic fluid temperature.
3. Lubrication system is also an unique part in diesel concrete pump, whose main function is to lubricate some parts and prevent concrete or mortar getting into those moving parts during the whole mechanical movement.
4.Pumping system, which belongs to mechanical system, is the core system. It consists of five key parts: the hopper, the S valve, concrete conveying cylinder, water tank and main oil cylinder. The hopper, welded by steel plates, is used for storing concrete to make sure the normal process of feeding. Valve connects the hopper and water tank, in which there are two concrete pistons. Water tank is the place to store water, and it is an important connector for main oil cylinder and concrete conveying cylinder. The last part is main oil cylinder. It is plated with hard chromium on the surface in order to avoid rusting.
When the pumping system starts working, with the influence of main oil cylinder, concrete pistons begin to move. Meanwhile, the S valve start to swing in accord with the movement of concrete pistons. By connecting conveying pipe with conveying cylinder in turn, the process of pumping is completed. And then it starts next circulation.
