- Q:I need a roller, but the search found different working principles of rollers
- The hydrostatic roller is obsolete and is a roller compactor that is compacted by its own weight.Vibratory rollerBy using the centrifugal force principle of vibration, the compaction strength is increased.purpose1 road, the road wheel compaction2 compaction when asphalt is laidPS: some vibratory rollers have the function of switching between vibration and static pressure
- Q:What do you mean by "380/275" in the vibratory force (kN) of vibratory roller?
- Or what it means.There are two modes of operation for a vibratory roller. The first mode produces the exciting force of 380KN while the other model produces the exciting force of 275KN.
- Q:Why use this roller when paving asphalt?
- The rubber tire roller through type kneading function, all work in horizontal and vertical direction, so that the mixture particles move and rearrange and close to each other, forming a contact surface and the roller contact the most stable aggregate. On the one hand to ensure the degree of compaction, reducing the double steel wheel road damage on aggregate; on the other hand, the aggregate and roller contact surface increases, under the same compaction condition, effectively reduce the possibility of aggregate crushing, improve the usage function of pavement.
- Q:How many tons of pressure are there when they are opened?For example: take a site earthwork flat, 20 tons of press vibration can affect on soil 30cm within the excavation area of soil compaction?, not loose.
- The amplitude of the same premise simply: imported 14 tons of original Dynapac roller is enough, influence Dynapac 19 tons of single drumroller depth is 1.5 meters. If 30cm can also affect the domestic 20 tons roller estimation however, do not know a test section. If you want to rent the equipment Dynapac compaction work can be found in Xuzhou Luqiao Gongli machinery limited company, they have more than 20 sets of dynapad single drumroller can be rented.
- Q:In the practical process, which one is the most practical? May I ask who can help me explain?
- the airport runway and the F1 track level is not the same, the higher the level, the higher requirements on and micro the overall structure of the pavement radian, the rubber wheel can be very good to meet these requirements, of course, only in the high requirements of the road we can see this kind of roller, usually in the side is not to see
- Q:31 How about roller?
- 31 is the momentum of the enterprise, but the road roller is always on the two row of Xugong boss. The product market, but overall is still approved by the quality of at least the price of this product, is still affordable. What maintenance, more complaints, quality defects and so on, of course, better quality and more stable imported brands to meet the requirements you use, but the price? Your wallet can meet the purchase requirements? Is the maintenance of the original brand.
- Q:What is the action of a vibrating gas? What is the principle of action and what is the working principle?.
- Three factors of magnitude of exciting force:The weight of a spinning object;The distance that the center of gravity deviates from the center of rotation (radius of rotation);Speed of rotation.
- Q:Rules for the operation of rollers
- 10. Other operating requirements shall comply with the requirements of the hydrostatic roller.No matter whether it is uphill or downhill, the bottom layer of the asphalt mixture must be clean and dry, and the asphalt binding layer must be sprayed to avoid sliding when the mixture is rolled.No matter whether it is uphill rolling or downhill rolling, the driving wheel of the roller should be behind. It has the following advantages: uphill, the driving force behind the driving wheel can withstand ramp and machine provided by their own, while the front wheels were initially on compaction, to withstand the large shear force driving wheel produces; downhill, impact roller weight generated by the driving wheel brake offset, capacity only by the mixture compacted to support the front wheel driving wheel produces shear stress.When rolling uphill, the start, stop and acceleration of the roller must be stable, so that the speed is too high or too low.Before the uphill rolling, the mixture should be cooled to the required low limit temperature, and then static preloading shall be applied. When the mixture temperature drops to the lower limit (120 DEG C), the vibratory compaction will be adopted.The sudden change of speed and braking should be avoided in downhill rolling.The slope is very steep downhill in rolling case, should use light roller pre pressure, followed by heavy rollers or vibratory compaction.
- Q:The dangers of young people turning on rollers
- Negatively speaking, lack of social experience is actually eat less, so you eat more slowly understand why the boss says that they make pressure on how how pressure, not with his nonsense, you say to him, he more angry, more than 10 hours a day and the boss asked people, a person carry not to live! I also drive the road ~ in the construction site must listen to.
- Q:How much oil consumption can the 20 ton roller run for 10 hours a day?
- Depending on the engine, fuel consumption is not the same, basically, the engine fuel consumption in 20 liters or so an hour.
