The open hydraulic system with three-pumps and three-circuits is adopted for HBT-S Valve Diesel Engine concrete pump.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 main pump come from Germany Rexroth.Japen Kawasaki and China Liyuan. Taper sealing and flange coulping can ensure the hydraulic circuit to be higher reliability, at the same time, it is simplicity and low cost to maintenance. The electrical components come from the world first class brands like JAPAN OMRON, KOREA LS,FRANCE SCHNEIDER etc. The PLC control is of KOREA LS and MITSUBISHI brand.The PLC control can conduct precise monitoring over the whole machine.To effectively avoid accidents caused by misoperation, multi automatic protection models related to temperature, rotation speed are set in the control programmer so as to prevent misoperation. The PLC of KOREA brand LS. Equipped wired or wireless remote controller upon demands is convenient to operation from long distance. 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 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.
