High viscosity pump can use insulation jacket structure, the transport of high viscosity materials can preserve heat of high viscosity pump, so as to reduce the viscosity of the medium to achieve better transmission effect, and single screw pump has no insulation jacket structure; high viscosity pump in use after a period of time, such as fruit gap within the pump wear and tear, do not disassemble the pump can according to their own high viscosity pump can transport the material viscosity to the adjustment of the pump clearance, adjusted and new pump can achieve good results. The single screw pump used for a period of time after wearing can open pump mounted inside the pump body of the rubber sleeve and single screw pump rubber sleeve in use especially easy to wear, thus greatly improve the single screw pump in use in the process of maintenance cost. High viscosity pump can be equipped with safety valve, when the pump or piping system overpressure, the safety valve open, the formation of internal reflux, to ensure the safety of the system. The single screw pump in the pump itself can not set the safety valve, can only be set in the pipeline to improve the equipment input costs and installation costs. High viscosity pump transmission medium viscosity of high viscosity pump selection must be considered, in order to to determine high viscosity pump speed range, according to high viscosity pump speed range and under the condition of high viscosity pump normal flow range, in order to determine the high viscosity pump specific models. Need to pay attention to the general medium can be so to choose. Among them, some special chemical medium under a certain temperature will change its chemical composition, so need in choose should pay special attention to the speed of the pump is suitable for high viscosity pump, because the pump speed is higher, the greater the heat generated in the normal work, once more than the limits of medium temperature, then the transmission medium caused damage. Also some food medium, than if the sauce, as we daily consumption in the jam, peanut sauce, bean paste and so on, these media requirements in the conveying process must not be able to damage the internal components were destroyed, which requires the selected pump speed must be low, in order to ensure the high viscosity pump in the transport process does not destroy the transmission medium.
