Trailer-mounted concrete pump

Main Pump REXROTH Hydraulic,Electrical, Distributing,Lubrication system

Hydraulic system:

The open hydraulic system of this product is made of combining three-pumps and three-circuits. Equipped special safety devices, such as constant power control, pressure cut-off control, promise the system to be more reliable than ever, and the equipped leading overflow valve makes the overflow to be more safety. The main pumping circuit and “S” valve circuit are independent to each other, which makes the work system to be more reliable and changeover steady. The tampered seals kits and Falan connection can ensure the seal of hydraulic circuit to be higher reliability, and simplicity and low cost to maintenance.

Electrical system:

24V direct-current supply is adopted for the electrical system. The electrical components come from the world-class brands, which guarantee higher reliability, easier troubleshooting. Diesel is equipped with automatic accelerograph,. Equipped wired or wireless remote controller upon demands is convenient to operate from long distance. Proximity switch used to control the direction of the main pumping ensures changeover steady and reliable.

Distribution system:

During the designing of key parts , such as hopper, “S” pipe and other vital components, the advanced modern design method is adopted to analyze its load distribution, construction rigidity and stress concentration, which makes the construction be more reasonable, and improve its rigidity and technology at the same time. The distribution system is equipped with floating anti-wearing ring, which can automatically compensate the wearing gap between “cutting-ring” and “spectacle-plate”, thus guarantees the out put pressure of pump. High wearing parts “cutting-ring” and “spectacle-plate” are both made of anti-wearing alloy to ensure their work performance and increase their service life. Many kinds of supporting wheels, such as manual controller, hydraulic lifter, etc. is provided for selection.

Lubrication system:The central automatic lubrication system comes with a piston grease-pump, features high pressure and reliability, which can realize automatic lubrication of piston. The filters at the outlet and the inlet of oil tank as double protections guarantee the system reliability.
