Q: Why should not be modified asphalt mixture roller compaction, and dense asphalt mixture should be used tire roller compound pressure?: For dense bituminous mixture aggregate due to small and continuous gradation, the tyre roller has the rubbing function makes the compaction layer of particles without destroying and interlocked, uniform and compact.

Q: How many tons are there in the maximum roller?: Static roller selection should also consider the large tonnage products, especially for the construction of the user only static roller, in order to improve the construction efficiency and compaction quality, the tonnage is best not less than 15t, after adding sand weight after weight should be more than 18t.Because of the existence of elastic deformation during the rolling process, the tire roller can play a role in kneading the compacted material, and can make the asphalt and other paving materials sealed and reduce the leakage of the pavement under the rain. According to the requirements of the new national standard "construction and acceptance of asphalt pavement" in our country, it is necessary to popularize and apply the large tonnage tire roller to re load asphalt composite paving.

Q: BMW roller, wrong wheel, will affect the straight line?: Normally, it doesn't matter unless your machine has been damaged.The roller should completely withdraw from the rolling operation period after vibration and stop slowly to avoid the wrong wrong wheel, wheel over a cause of asphalt mixture passes and squeeze the mixture.

Q: It is feasible to build a 2 story building. The foundation is compacted by roller: Building foundation on the one hand is to bear the weight of the house, on the other hand, it is also necessary to ensure the uniform settlement of the house, otherwise the house will crack. No foundation, the house can not be built, there is no construction master dare to build.

Q: Why is the price difference so large? Is there a problem of repeated calculation?: To meet the requirements of doing subbase filling and rolling; including earthwork backfilling, bulldozer, layered rolling to meet the design requirements of the degree of compaction, the smoothness of the road not good.No double counting, for example, road subgrade backfill, backfill compacted well, if you want to do is road subbase, rolling, if it is not just the general fill roadbed RCC.

Q: Roller roller do large objective: Only two can press the road more tightly, so as to achieve a certain degree of compaction, width is to work efficiency, the greater the area of contact, the pressure will rise faster.

Q: Working principle of vibratory pump and vibrating motor: The motor drives the gear pump of the hydraulic oil circulation, and then to the vibrator here, the hydraulic oil circulating through the hydraulic gear into rotary force (hydraulic motor, and the motor is also popular that a truth, only substation, power transformation) let you through a transmission shaft. To an eccentric rotor to rotate, so there is a shock.

Q: The working principle of roller: The working principle of the roller is as follows:1 、 roller is a method of using mechanical weight and vibration to repeatedly load the compacted material to overcome the cohesion and internal friction between the materials.2, to exclude its internal gas and water, forcing the particles between the displacement, wedge close each other, increase the density, so that it reaches a certain degree of compaction and integrity of the operating machinery.

Q: Let me have some never played roller! 10 years 22 tons for 22W mountain people think? What are the disadvantages of this roller?: Look, feel stingy, and fourteen tons of sixteen tons, and the machine is like 11 years, 10 years, and only 200 thousand, Xugong function higher than the rest of the domestic brands, all below one hundred and eighty thousand, the new 30 bit mountain, over three years, I sold one hundred and fifty thousand, I also consider quite a long time, and the truth,,

Q: Where are the rollers attached to the rollers?: Upstairs said that the diesel engine oil, generally can find. Inside the reducer roller and the gear oil, is a heavy load gear oil, the Great Wall, Kunlun, Mobil, Shell and other series, such as the Shell VG150 heavy load gear oil, Mobil 629 series, the Shell VG150 gear oil is prescribed brand models of Sany products, and in the steel wheel and driving speed reducer vibration wheel, Shell VG140 gear oil filling in single drumroller rear axle reducer. Other brands of roller gear oils may have different brands and models. The steel wheel driving speed reducer addition: two is 90 degrees, and put the oil nut, screw it loose, start the engine running, one oil discharge outlet vertical reducer gear oil released after walking again, the two oil outlet of a vertical and a horizontal from the beginning, at the top of the filler filling gear oil, until the level direction of the oil port gear oil out of date. Refueling capacity of about 4.5L. Vibration wheel gear oil additive: three a 120 degree uniform oil adding and discharging port, oil discharge method ibid, to a vertical oil port down oil, after the oil discharge screw on a rotating steel wheel nut, make an oil outlet straight up, another loose oil the mouth slanting down (because the three port is 120 degrees.), from the mouth to the oil filling oil, until the oil port oblique gear oil out of date. Refueling capacity of about 11.5L. After oil addition: gear reducer bridge observation hole loosen nut central, loosen the direction by the reducer and put the oil nut oil (rear axle oil adding and discharging nut good judgment, nut at the top of a concave circular), and then go nuts loosen upper, middle gear oil to observe the outflow of oil can. Refueling capacity of about 18L. The above for Sany roller filling gear oil method and dosage, other brand roller may be different, but should be very similar, hope to help LZ.
