Q: The front wheel of a road roller is known to be cylindrical, with a width of 2.5 meters and a diameter of 1.2 meters. The front wheel rotates 8 minutes per minute. The 1. roller takes 20 minutes from one end of the road to the other. How many meters is the length of the road?. 2. what is the area of the road roller from one end to the other end of the road?. Process and description: 4, from one end of the road to the other end, the area of the road is equal to the length of the front wheel and the width of the wheel, or =602.88*2.5=1507.2 (square meter).For reference.

Q: Roller three tons, what kind of good?: It's good for Sakai to vibrate both before and after. Vibration can be separated from front to rear.

Q: The front wheel diameter of the roller is 1.6m, and the width is 2m. What is the area of the roller that rotates for one week? M2: Solution: it is known that the front diameter of the roller is 1.6 meters and the width is 2 meters,The front wheel is rotated for one week, the area of the roller = the front wheel's perimeter * width=3.14 * front wheel diameter * width=3.14 * 1.6 * 2=10.048 square metersA: the front wheel is rotated for one week. The area of the roller is 10.048 square meters.

Q: XCMG alarm lamp for vibratory roller: Since then, in addition to February, because of the Spring Festival factors are relatively low sales, from March, Roller Road sales all the way up, April is a substantial increase of 30.7%, reaching the peak in 2013 sales. Since then, each month has maintained a year-on-year growth trend, and some months of year-on-year growth of even more than 40%. From the sales situation, the eastern region (Beijing, 2013 Tianjin, Hebei, Liaoning, Shanghai, Jiangsu, Zhejiang, Fujian, Shandong, Guangdong, Hainan) roller sales of 4834 units, an increase of 24.33%; the central region (Shanxi, Jilin, Heilongjiang, Anhui, Jiangxi, Henan, Hubei, Hunan) pressure the road machine sales of 3436 units, an increase of 27.68%; the western region (Sichuan, Chongqing, Yunnan, Guizhou, Tibet, Xinjiang, Gansu, Qinghai, Ningxia, Shaanxi, Inner Mongolia, Guangxi) roller sales of 4061 units, an increase of 20.33%.

Q: Why should we use the rubber tyred roller in the construction of the asphalt pavement?: Look, the problem has been vacant for so long. Let me answer it.My answer to this question is limited to asphalt pavement construction. Hot mix asphalt is a mixture of heated stones, aggregates and heated liquid asphalt, mixed with fillers (such as ground mineral powder) and additional additives (fibers, etc.) at mixing stations. Take the truck to the construction site when it is hot, then pave and compaction.The asphalt mixture must be kept at a higher temperature during compaction, in order to ensure a certain density (compactness) after compaction.There are three types of rollers I know: steel wheel rollers, rubber tyred rollers and vibratory steel roller.

Q: How about mountain road roller: Well, I have several friends to buy the mountain road roller is Shantui bulldozers can, nothing else, Shantui roller faults, the cab is too small, no foot throttle roller, the rest of the brand are a foot throttle a hand throttle, Shantui gear is convenient. Variable magnetic valve gear selector is convenient, easy, not a bad five thousand or six thousand, also love the bad, there are disadvantages you strong,

Q: Why can't we use the tire roller in the modified asphalt road?: Can not generally say that modified asphalt pavement can not use tire roller. We know that SMA asphalt layer can not be used in tire roller rolling, because the SMA asphalt mixture aggregate gradation and aggregate gradation is not continuous, relatively large, and the modified asphalt content is relatively higher, when using the tyre roller, tire roller is very heavy, tire ground the pressure is large, easy to SMA asphalt layer of modified asphalt mixture from the voids in the extrusion, it is not up to the role of the SMA asphalt layer, from the analysis of this meaning is not used tire roller. For the highway, the asphalt layer has three layers, in order to save money, in the surface layer is used instead of the base asphalt, modified asphalt, and this phenomenon is not that modified asphalt pavement can not use tire roller, on the contrary, the asphalt pavement is matched with the need of tyre roller to achieve good compaction effect, including modified asphalt. The asphalt is hot, the tire will bond in asphalt, a tire pressure will mark is not scientific, if afraid of this and that, without the use of tyre roller, for the asphalt pavement, is to pick a watermelon seed lost performance for the asphalt pavement compaction effect, not only is the most terrible.

Q: How is the tonnage of the roller machine calculated? Forget to know the answer! Thank you: Xugong seems to be the quality distribution before and after, plus the high and low vibration, how to count, I forgot, will know high vibration 28, low vibration 32

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.
