Truck-mounted Line Concrete Pump

Description:

MAX.THERO.ConCRETE OUTPUT (L./H.):88/57 m3/h
MAX.ConCRETE PUMPING PRESSURE (H. /L.):14/9 MPa
ENGINE MODEL:TAD720VE

A, Hydraulic system
1.The vehicle adopts double-pump double-circuit open hydraulicsystem, the main pump oil circuit and S valve swinging oil circuitare independently, this simples the system, prolong the servicelife of components, gain higher reliability and is convenient forchecking and solving faults.
2.For switching needs of the pumping circuit, the pilot operateddirectional valve with external control pressure-reducedeffectively avoids shock during switching; the result is a steadyand reliable system.
3.Pumping circuit is protected by a relief valve; moreover the oilpressure of the main oil pump can be shut off automatically whensystem is overpressure, so the main hydraulic pump can acquiremultistage reliable protection at on time.
4.The switching circuit driven by the constant pressure pump canrealize big switching strength and energy-saving at the sametime.
5.All pipes are cone sealed; it can ensure high reliability onsealing of tube connections.
6.The adoption of high and low voltage reverse valve avoidstroubles of pipe dismantling and oil filling.

B, Electrical control system
The outstanding characteristic of the electrical control system issimple, reliable and advanced in technology.
1.90% of the electrical components are original imported fromJapanese companies such as OMRON and MITSUBISHI, thus ensure thereliability of the components.
2.Compared with the similar products in domestic, the electricalsystem is the simplest, the number of components is the least, andthe reliability is the highest.
3.Equipped with wired remote controller, which is convenient forlong-distance operation.
4.The adoption of the proximity switches can realize contactlessdirection changeover reliably.

C, Mechanical (mixing) distribution valvesystem
1.The design for key parts of hoppers, S valve and etc. adoptsI-DEAS program to finite element calculate its load condition,calculate construction rigidity and stress concentration. Theoptimized hopper and S valve system can effectively avoid thefollowing phenomena like hopper distortion and shaft break of Svalve during conveying under high pressure, 2000 Zoomlion pumpsthat were put into market have well proved that.
2.The mixing mechanism is particularly designed that hydraulicmotor is completely separated from bearing seat, thus the motorwill not be influenced in case of sealing failure. Meanwhile, largecapacity motor is equipped to ensure that the mixing moment isenough, and normal mixing would not be disturbed even whenmaterials are in bad conditions.
3.Wear parts like glass plate and cutting ring etc. have longservice life up to 20000 m3. Service life of Zoomlion glass platesand cutting rings are 50% longer than other companies in domesticindustry in the competition in construction site of Shenzhen Postand Telegraph Building.

D, Power system
Original imported DEUTZ diesel engine is excellent in performanceand own high reliability.

E, Lubrication system
It adopts patented central automatic lubrication system; thepressure filter at the outlet guarantees the reliability of thesystem.

F, Cooling system
Compulsory air-cooled heat exchanger keeps the operatingtemperature of hydraulic system below 60°C, which ensures the wholehydraulic system work under normal condition.

G, Cleaning mechanism
Cleaning machine is equipped for the convenience of maintenance andcleaning.

H, Chassis
second class chassis such as EQ1108G6DJ15 (China 2 ) andEQ1126KJ1(China 3)from Dongfeng Motor Company Limit are adopted.They are flat head with double berth steering room, 4×2drive,equipped with Cummins engine. The chassis featured mature,reliable, powerful, economical and well performance.
