Insulating asphalt pump structure and use

The high-temperature insulation asphalt pump has common materials, cast steel materials and stainless steel materials. All of them adopt one-piece non-discharging full-insulated jacket structure. According to the site conditions, the thermal insulation medium such as thermal oil, steam, and hot water can be used to insulate the pump. The pump mainly uses involute herringbone type, low noise arc gear type, spur gear high pressure type three kinds of gear structure form. Suitable for conveying all kinds of non-solid particles, the temperature is not higher than 350 °C heavy oil, asphalt, plastics, resins, detergents, etc. At room temperature, there are solidification and cold areas where outdoor installation and process require insulation High viscosity media. Stainless steel material can transport all kinds of high-viscosity, corrosive media where there is coagulation in normal temperature and outdoor installation and process in the cold area.

Insulation asphalt pump adopts double arc point meshing gear transmission. A sufficient tooth width can achieve multi-tooth meshing, and each pair of teeth has two meshing points with a large radius of curvature at the meshing point. Therefore, the multi-meshing double-arc gear has high contact strength, smooth transmission, and low noise. After the bearing runs, the point contact is gradually changed to line contact, and the sensitivity of the line contact of the involute gear theoretically to the manufacturing installation error is abandoned, the load concentration is prevented, and the bearing capacity is improved. Double circular arc roots are strong and have high bending strength. The point meshing does not have the different sliding speeds at the meshing points of the involute gear, which improves the transmission efficiency and the service life.

In order to improve the volumetric efficiency, tight seals are made everywhere. Rotary dynamic seal adopts special packing, which is resistant to wear under high temperature and has good sealing effect. The lower part of the pump body is provided with a heat-conducting oil storage and flow space, which heats the asphalt and ensures that the conveying medium, the asphalt, is always above the pumping temperature and is convenient for transportation.

Insulating asphalt pump has two structural forms for each specification: the motor is directly coupled with the active pump shaft through the coupling (direct connection type) and adopts six-stage motor; the motor is connected with the active pump shaft through a pair of deceleration pulleys (PIP ), useful four-stage motor.

Asphalt gear oil pump is used in the transportation and spraying of liquid asphalt in the asphalt mixture mixing equipment. It is also an ideal equipment for bitumen plant (station) asphalt transportation, canning, discharging and spraying. It can also be used for other high-viscosity media.
