What are the characteristics of the screw pump?
Shortcomings are also obvious, knowledge can be used: 1, due to the inter-rotor friction, the need for greater torque.
2, more prone to dry grinding, high temperature, damage to rubber and other materials, the stator, the stator and the seal is the same supplies.
Efficiency is low, often shaft absorption power 1kw, manufacturers will be equipped with 3kw or even larger motor.
Compatible with high solid content, with particle conditions.
2, low shear; 3, self-priming performance is good; 4, to adapt to very low to very high viscosity; 5, low-speed, high-speed, low-
