Three screw pump selection, to be as detailed as possible to understand the conditions of the pump, in addition to the operating parameters, such as flow, pressure needs to be clear, the characteristics of the transmission medium such as media corrosivity, gas content, solid solution containing the ratio And the size of the solid particles, as well as the medium temperature, viscosity, specific gravity, corrosive materials such as pumping equipment and suction conditions, installation conditions should be understood, according to our experience, three screw pump selection should pay attention to the following Point: 1, the choice of three screw speed 1.1, the transmission medium viscosity and pump size to determine the speed range: When transporting high viscosity medium, the pump should be selected low speed, if the viscosity is low, the corresponding choice of high speed; medium viscosity> At 20 ° E, the speed is reduced to 970 rpm or 720 rpm for large size three-screw pumps (main bar outside diameter 60 mm and above). If the viscosity is higher (viscosity> 80 ° E) Recommended 200-500rpm; for small three-screw pumps, medium speeds> 20 ° E, speeds of 1450rpm or 970rpm, higher viscosities (> 80 ° E) Can reduce the speed of use, recommended 300-600rpm; 1.2, due to the higher pump speed, the same performance parameters, the smaller the pump size, but because of high speed, high friction power, pump wear large, short life expectancy If the lubrication medium is poor or contains traces of impurities, you should choose a lower speed, so that the pump to maintain a longer life, recommended below 1450rpm. 2, the choice of structure can be based on the installation and use of the pump reference to the three screw pump series and type, in principle: 2.1, conveying lubricated oil, the temperature below 80 ° C select the built-in bearing structure of the pump; 2.2, The pump with external bearing structure is selected when the temperature is over 80 ° C or the lubrication of the conveying medium is poor; 2.3, the pump with poor fluidity and high viscosity or the pump with double-layer heating structure is selected when the medium to be conveyed needs heating or heat preservation ; 2.4, high temperature conveying, should choose the pump made of high temperature resistant material, please contact with our factory. 3, matching motor matching pump selection is determined, according to the sample data can be found three screw pump shaft power N, the shaft power coupled with a certain power reserve, as a basis for matching the motor, the general motor power Nm should not be less than the pump shaft power N multiplied by the power reserve coefficient of three screw pump flow, pressure in the same speed, viscosity is approximately linear relationship, the higher the pressure, the smaller the flow.
