Gate Valve Concrete Pump

The structure of “Gate” valve makes Zoomlion Concrete Pump feature perfect suction, possess the capability to satisfy different demands on jobsites. There are two kind of power sources on your request: electrical motor and diesel engine.

Hydraulic system:

The sequential circuit comes with a pump made by renowned manufacturers. The pressure oil from the pump is first delivered to the “Gate” valve cylinder, which ensures that only after the “Gate” moves to the predefined position can the main cylinder begin to move.

The “Gate” direction control circuit is separated form the pumping direction control circuit by a pressure- reducing valve. An accumulator on “Gate” valve direction control circuit ensures the reliability of changeover of the “gate” valve.

The block valve control the motion of the main cylinder and the “Gate” valve cylinder, which simplifies the system hosing and enhances the maintaining accessibility.

The Mixing system can reverse automatically. If the mixing vanes are blocked by stuff during operation, the vanes will be reversed automatically to eliminate the trouble when the size of aggregate is not ideal.

The taper coupling with O-ring embedded in the taper at tube connection side, and the BS rhombic ring, achieve good sealing performance.

Electrical system:

Features advanced technology, effortless operation, high reliability

Comes with a Programmable Logic Controller (PLC), which takes the place of many relays, time relays, which not only greatly reduces components but also simplifies wiring in the system, ensures a higher reliability. In combination with PLC, a visual display can indicate the status of inputs and outputs, lead to an easier troubleshooting.

90% electrical components supplied by the world-class brands guarantees the system high reliability.

In comparison with the domestic products, our electrical control system is much simpler, with less components and higher reliability.

Equipped remote controller or cable remote controller upon demands is convenient to operate from long distance.

Deutz Diesel engines, Equipped with electronic accelerator device.

Mechanical system:

By a special design on sealing structure of agitator, hydraulic motors are completely separated from bearing seats, even under the situation of sealing failure, the slurry has no chance to get into motor. High-- torque motors ensure high mixing torque. Thanks to the auto-reversing device and anti-wearing blades, the blockade will never happen even under severe aggregate condition.

Related to the design of mixing vane and hopper, software I-DEAS is adopted to realize Finite Element analysis of load distribution, construction rigidity and stress concentration. The optimally designed hoppers made of anti-wearing material possess excellent rigidity, suction features and concrete charging.

The upper and lower pedestals of “Gate valve” are interchangeable which is convenient to maintain.

Lubrication system:

The patented 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 ports as double protections guarantee the system reliability.

Cooling system:

Compulsory air-cooled heat exchanger keeps the operating temperature of hydraulic oil below 60℃，that ensures the whole hydraulic system work at normal status.

Cleaning device:

Equipped water pump makes the cleaning and maintaining an easy job.
