High temperature bitumen pump with common material and stainless steel and cast steel material, all using one-piece leak-free full insulation jacket structure, can be based on the conditions of their own field can be used HTF, steam, hot water and other thermal media for pump insulation The pump mainly adopts involute herringbone gear type, low noise arc gear type and spur gear high pressure type three gear structure forms. It is suitable for conveying all kinds of heavy oil, asphalt, glue, resin, detergent and so on which are free from solid particles and not more than 350 ℃ .It is suitable for outdoor installation and process insulation in normal temperature High viscosity media. Stainless steel can transport a variety of conditions at room temperature in the freezing and freezing of outdoor installation and process requirements of the occasion of insulation high viscosity, corrosive media. Insulation asphalt pump with double arc point gear transmission. Tooth width sufficient to achieve multi-tooth meshing, and each pair of teeth have two meshing point, meshing point at a large radius of curvature. Therefore, multi-point meshing double arc gear with high contact strength, smooth transmission, low noise. After the carrier runs, the point contact becomes linear contact gradually. The sensibility of the line contact of the involute gear to the manufacture and installation error is avoided, the load concentration is prevented and the carrying capacity is increased. Double arc tooth root stronger, high bending strength. There is no point meshing involute gear meshing point has a different sliding speed, improve the transmission efficiency and service life. In order to improve the volumetric efficiency, sealed everywhere. Dynamic dynamic seal with a special packing, wear-resistant under high temperature, sealing effect is good. Heat pump oil storage and flow space is set in the lower part of the pump body to heat the asphalt to ensure that the conveying medium - asphalt is always above the pumping temperature and is convenient for conveying. Insulation asphalt pump specifications for each of two structures: the motor through the coupling directly with the active shaft coupling (direct connection), the use of six-stage motor; motor through a pair of deceleration pulley and the active shaft coupling ), Useful four motor. Asphalt gear pump used in asphalt mixing plant liquid asphalt transportation and spraying work, but also asphalt plant (station) asphalt conveying, canning, unloading, spraying the ideal equipment, but also for other high-viscosity media.
