What are the advantages and disadvantages of screw pump?

[Asia Fluid Network News] screw pump performance in the main through its flow, power, speed, diameter, temperature and other parameters shown. At the same time through these parameters, it shows its characteristics, which not only has the advantages of screw pumps, but also has its shortcomings. Next, the specific analysis of the advantages and disadvantages of the screw pump which. Screw pump advantages: 1, a wide range of pressure and flow. Pressure of about 3.4-340 kgf / cm2, the flow rate of up to 100cm3 / min; 2, the type and viscosity of liquid transport a wide range; 3, because the pump rotary inertial force is low, it can use high speed; 4, good suction performance, self-priming capability; 5, uniform flow rate, small vibration; 6, compared with other rotary pumps, the gas and dirt into the less sensitive; 7, solid structure, easy installation and maintenance; Pump shortcomings: 1, the screw machining and assembly requirements are higher; 2, the pump performance is sensitive to changes in the viscosity of the liquid; 3, the pump vibration or noise; through the above analysis of the advantages and disadvantages of the screw pump, we It can be relatively clearly understood that the screw pump is a kind of work pressure, large working flow pump equipment, in its work, it's high speed, can protect the work efficiency, the normal maintenance work is also simple, for people's production and use provided Good help. Although it has some shortcomings, its use is still widely acknowledged.
