The sweeping of the sweeper is one of the more important parts of the whole car, and it can't be ignored. If there is no sweeping function, then the work of the sweeper will not work. The sweeper's The brush is also a relatively easy accessory to wear out. The original sweeper of the Warwick Olympiad has four brushes, which need to be replaced after 6 months under normal use conditions. Of course, for this 6 months The deadline will still depend on the road conditions used. So what kind of sweeper sweeper is considered to be of good quality? What kind of performance is required for those qualified sweepers?
1, the domestic sweeper sweeper sweeping materials mainly include nylon wire, steel wire, lead wire and mixed materials. Lead wire and steel wire are superior to mixed materials and nylon wires in terms of wear resistance, and they are large in weight, high in strength, and high in one-time investment cost. Nylon filaments are relatively lightweight, and the cost of a one-time investment is relatively low, but the use of the line of sight is relatively short, and the wear resistance will be relatively poor. The material used in the practical work of the road sweeper is SFT-4 polytetrafluoroethylene filler. Although the material may be inferior in mechanical strength, the material will have better wear resistance and lighter weight. It is made using twenty percent glass powder and five percent graphite filled with polytetraethylene. The pull strength was 6.865 MPa and the density was 2.2 kg/cm3. The sweeping car had a 50 percent elongation at break when it was cleaned.
2. Because the suction port of the sweeper is below the drive shaft, the two central sweeps are symmetrically arranged on both sides of the drive shaft. The front cloth sweep is placed on the right side of the cab, which makes it easier to clean the trash in the gutter. When the driver of the road sweeper got to the front of the sweeper, he could see the work of the front sweep. He could reach the certain position while sweeping and extending. In the middle of the sweeper, both the vertical sweep and the front sweep are the used pattern brooms. When setting up the sweep, it should be taken into account that there is a certain degree of overlap between the broom and the wedding.
3. The calculated weight of the sweeper broom is composed of a concentric motor, a hydraulic motor, a blade, a blade seat, and the like. The service life of the sweeper has a major relationship with the road conditions, usage conditions, operating skills, and the quality of the sweeper. (Text / Sun Ni)
