Working principle
Screw pump is a propulsive volumetric pump, the main components are the rotor and stator, the rotor is a large lead and a large tooth height and a small spiral inner diameter of the screw (rotor) stator is matched with the double screw thread and the screw sleeve, so that between the rotor and the stator formed the storage medium space, when the rotor is running in the stator, the medium along the axial from the suction end of the discharging movement. Work characteristics
-The spiral seal in contact with the stator and rotor completely separates the income chamber from the discharge chamber, so that the pump has the isolation effect of the valve.
-Multi-phase mixed transport of liquid, gas and solid can be realized.
-The volume does not change when the fluid flows in the pump, there is no turbulent stirring and pulsation.
-The volume cavity formed by the elastic stator can effectively reduce the abrasion of the medium containing solid particles.
-Input medium viscosity up to 5000MPa-S solid content up to 50%.
-The flow rate is proportional to the rotational speed, and the automatic adjustment of the volume can be realized with the help of governor.
-Pumps can be positive and negative conveying.
Advantages
Compared with the centrifugal pump, screw pump does not need to install valves. Its flow is stable and linear.
Compared with the plunger pump, screw pump has strong self suction capacity and high suction height.
Compared with diaphragm pump, screw pump can transport various mixed impurities containing gas, solid particles or fiber media, and can also transport various corrosive substances.
Compared with gear pump, screw pump can transport substances with high viscosity.
Unlike plunger pump, diaphragm pump and gear pump, screw pump can be used for reagent filling and metering.
