Technical Features

(1)The diesel engine installed is suitable for the projects with insufficient electric power supply. The diesel engine adopts original VOLVO diesel engine, featuring strong power and prominent performance.

(2)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. The main oil pumps and valves adopt world’s renowned brand products to realize high system stability and reliability.

(3)The full-hydraulically controlled reversing technology guarantees more reliable and stable reversing motions for the main pumping line.

(4)he one-touch automatic high/low pressure switchover features convenient operations.

(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 main electric control units adopts the original imported products (such as German Siemens products) to guarantee the reliability of the units.
