Slurry Seal Paver DAW12-K43

1.Equipment use

Slurry seal paver DAW12-K43 consists of the chassis, feeding system( aggregate, emulsion, water, padding, additive),mixing system, paving system, power system, and control system.

Its main purpose to manage the pavement surface diseases such as frictional resistance declining, crack or track, to enhance the skid resistance and water repellency, to improve the pavement flatness and driving comfort, thus achieve the best effect of new pavement from old one. It’s also widely used in the construction technology of common slurry seal, modified slurry seal and micro surfacing.

2.Working principle

Slurry seal paver’s working principle is to convey the aggregate, powder material, water and emulsified asphalt to the mixer within certain rate; form flow emulsified asphalt slurry mixture through fast mixing and convey to the paver; after spiral conveying pave evenly and smooth on the road.

Slurry seal paver is the equipment specially used for slurry sealing technology, which can meet the special construction condition with the short time mixing, shaping up fast and thin paving thickness, thus the requirements of fast construction, low cost, wide uses and energy consumption.

1 Sinotruk Howo Ⅴ special chassis, low fuel consumption and emission, strong power, comfortable and convenient driving;
2 intelligent low speed passing-stress mechanism from the special chassis output torque, with working stable speed and good construction effect
3 the auxiliary engine is YUCHAI high-power engine, with strong power; the paving effect perfect when manage the modified asphalt in breaking of emulsion.
4 aggregate storage bin, emulsified asphalt tank and water tank recombines together with compact structure, high efficiency and good shape.
5 l iquid storage tank and pipeline is welded preciously with the stainless steel, anti-corrosion and long-life.
6 maximum mixing capacity is 3.5t/min, which can meet the different width, thickness and different construction requirements, with excellent construction performance.
7 open hydraulic system with compact, beautiful structure and high liability;
8 use famous brand hydraulic power from German, conveying revolving speed stable and reliable; the accurate control of the conveying materials is realized with the advanced measure sensor.
9 Single road single control, with five sets of independent hydraulic power sources, dynamic stable and non-interference. It is convenient to troubleshoot, good for maintenance, especially for system upgrade.
10 Operations using the rear control platform, the operators can control all components of action on the platform, and achieve a single button to start and stop, conveniently and quickly.
11 With advanced stirring and mixing plant, the pulp is good. The wear-resisting blade is built of hard alloy grain, and the material Angle can be adjusted vertically to suit the construction of the road surface.
12 The control system adopts the modular design and special controller of the engineering machine, with high protection grade and strong driving ability.
13 Accurate material deficiency alarm device is used to monitor the loss of aggregate delivery during construction, and ensure the quality of construction.
14 The emulsion pump with steady flow is adopted, and the emulsion quantity can be accurately supplied by the advanced measuring sensor. The pump body has the heating function, which meets the needs of the tough working environment. At the same time, the structure of the system can be realized from the self-suction filling oil function, convenient to work.
15 The humanization design, has high, low pressure two sets of washing equipment. Construction and equipment maintenance is more convenient.
16 Automatic tyre water spraying system, meets the requirements of special process in construction.
17 A high pressure cleaning device and a spreading water supply device, provides convenient conditions for the normal cleaning and maintenance of equipment and special construction process.
18 The innovation design of bin vibration device effectively solved the problem of "collecting materials frame", which greatly improved the construction quality.
19 Aggregate storage capacity is to 10 m3; 55° inclined wall makes aggregate blanking smooth.
20 T he paving system adopts automatic telescoping pave box, which satisfies all kinds of pavement construction requirements, and can adjust the suitable arches according to the construction needs; Adopts double row screw propeller, the structure has the effect of distributing materials and secondary mixing materials, and the effect of preventing the slurry separation is obvious.
21 There is a CAN bus connection between the master controller(world famous brand) and the extension module, which is flexible in the distribution box. Using distributed bus control, the controller directly drives the control component, greatly enhancing the stability and consistency of electric control.
