85m3 Trailer Trailer Pump

(1)The double-pump double-circuit open hydraulic system is adopted, in which the main pumping line and the S valve swing line are independent with each other to simplify the system and realize higher reliability. (2)The master oil pump, constant pressure pump, and hydraulic control units adopt originally imported products from world`s renowned brands, with automatic over-pressure cutoff device, featuring reasonable structure and powerful performance.(3)It's equipped with high/low pressure switching function to ease the choice of pumping mode depending on the working condition.(4)The full-hydraulically controlled reversing technology guarantees more reliable and stable reversing motions for the main pumping line. (5)The automatic retraction function of concrete piston can retract the concrete piston to the washer chamber to greatly ease the checking, repair, and replacement of the concrete piston. (6)The S-pipe valve is adopted, in which the S-pipe is bead welded from imported wear-resistant welding rods and the shaft end is treated by nitriding of high strength alloy steel to prevent the rupture of shaft end and promote its service life. The wearing plate and the cutting ring are made of wear-resistant hard alloy to remarkably improve the service life.(7)The electronic control system adopts PLC control system and integrated switching power supply, featuring advanced, reliable, simple, and practical technologies. (8)New mixing mechanism adopts
