A screw pump is an ideal pump that use one or several screws to move fluids or solids along the screw(s) axis to the oil drilling mud decanter centrifuge. This pump has a strong adaptability to medium, smooth flow, small pressure fluctuation and high suction capacity. With unique design of rotor and stator, low rate of pump internal flow and more stable pressure. The drilling fluids screw pump can also be used in the drilling waste management for wet mud and cutting transportation.
Screw pump working principle
The single-screw pump, a type of rotary positive-displacement pump with internal gearing, it is mainly composed of a stator with dual spiral chambers and a rotor engaged with the stator in the shaft bushing.
When the rotor is making planet turning movement by circling the axial line of the stator in the stator chamber, the sealed chamber formed between the rotor and stator will make axial displacement along the spiral line of the rotor, which will convey the liquid evenly and continuously from the suction to the discharge side.
The features of Aipu screw pump
1. Low pulsation for smooth and quiet operation.
2. Direct-drive and easy to operation.
3. Low shear for protection of the pumped fluid.
4. Hydraulic balance for minimal deflection and wearing.
5. Cartridge-type rotating assembly for easy servicing.
6. Integral relief valve to eliminate external valves and piping.
7. Built-in heat jacket to facilitate cold start.
8. Customized ports to adapt best piping arrangements for the system.
9. Selecting materials for the longest service life.
