Overhaul of the impeller and the rotor Asphalt pump, three screw pump is a positive displacement pump, a significant advantage of simple structure, small size, allowing high-speed, smooth and reliable, pressure pulsation, flow stability, low noise, high efficiency, high viscosity heat pump. Library for asphalt, oil, heavy heating oil tanks and steam heat-conducting oil, bitumen, heavy oil and other ancillary equipment. 1, the working life of the asphalt heat pump, the factory is not included in the pilot project, is the type of pilot projects. To ensure the quality brand-name manufacturers should choose regular. 2, the asphalt heat pump system: sub-system of long-term, repeated short-term and short-term work system work system three. Conventional products are long-term work system, which allows long-term power coil work. For a long time only a short-term closure of the valve opening of the case, are advised to use heat pumps normally open asphalt. Short-time work system used in large quantities when they can be used as a special order to reduce power consumption. 3, the asphalt heat pump frequency: high frequency requirements of the action, the structure should be optimized direct-acting asphalt heat pump, AC power optimization. 4, asphalt pump operating reliability...
