Description of trailer concrete pump for sale :
Concrete pump is consist of pump, hydraulic system and pipeline, it
could convey ready concrete under pressure through the pipeline
continuously and it mainly used in the building, bridge and tunnel
System introduction of trailer concrete pump for sale:
I. Hydraulic system of trailer concrete pump
1. The products adopts double-pump and double-circuit open
hydraulic system. The pumping hydraulic circuit and S valve swing
post hydraulic circuit work separately, which makes the system
simple, component life extension, higher reliability, and is easy
to fault judgment and ruled out.
2. In view of the weaknesses of big reversing impact of start
system, technology is used to pumping hydraulic system to control
pilot relief, which avoids the reversing impact and makes the main
pumping hydraulic system more reliable and stable.
3. Pumping hydraulic system has safety overflow protection. At the
same time, when system is over pressure, oil pump pressure
automatically cuts off the interception device to make the main
pump obtain more reliable protection.
4. Swinging oil-way adopts constant pressure pump to supply oil. It
has great swinging strength and energy-saving function.
5. All pipe line adopt taper sealing or rectangle sealing, and pipe
joint sealing is reliable.
II. Electric control system of trailer concrete pump
The outstanding features of electric control system is advanced
technology, easy operation and high reliability.
1. 90% of the electric elements are supplied by Mitsubishi Japan,
which guarantees high reliability.
2. Compared with the domestic similar products, the electric
control system is most simple, with the minimum quantity of
components and highest reliability.
3. With wire remote control, it could be convenience to operate.
4. The adopted contactless commutation of proximity switch ensure
the reversing reliable.
III. Mechanical (mixing) distributing valve system of trailer
1. The design of the main force-summing element, such as hopper and
S valve, adopt the mechanical engineering mechanics calculating
program. Through this subdivision mesh finite element calculation
to its stress state, structure system, the condition of stress
concentration, the hopper and S valve have good structure steel
level and manufacturability, which is useful to avoid the
phenomenon of hopper distortion and S valve broken in the condition
of high-rise pumping.
2. The agitator has unique structure, which totally separates the
hydraulic motor and agitator bearing block. It will not influence
the hydraulic motor even if there is seal abrasion and slurry leak.
Meanwhile, using single motor can avoid the agitator’s mixing
torque out of sync caused by bi-motor under the condition of the
concrete material abnormal.
3. The service life of wearing parts such as spectacle plate and
cutting ring is long after continuous technical research. On the
best pumping condition, it can pump 20000m3.
IV. Lubrication system of trailer concrete pump
The lubrication system has concentrating automatic lubrication
system; Pressure increment device and filter are fixed on output
port of lubrication pump to ensure the lubrication system more
V. Cooling system of trailer concrete pump
The big radiator equipment of forced cooling makes the working oil
temperature of hydraulic system below 60°and ensures the host of
the hydraulic system in a normal state.
Application of trailer concrete pump for sale :
1) Conveying floor heating lightweight foamed cement, mortar, fine
2) Conveying refractory and insulation materials
3) Conveying greening soil in ecological environment construction
4) Conveying all kinds of engineering construction in the plain
concrete, fiber concrete
5) Pressure grouting of foundation pile
