Work Principle
The screw pump is a propelling positive displacement pump. Its main components are the rotor and stator. The rotor is a screw with large lead, high tooth height and small spiral inner diameter. The stator is matched with the double head spiral and the screw sleeve. This creates a space for storing media between the rotor and the stator. When the rotor operates in the stator, the media moves axially from the suction end to the discharge end.
Working Characteristics
⚙️
The spiral seal in contact between the stator and rotor completely separates the inlet and outlet cavities, providing the pump with a valve isolating function.
🌀
It can achieve multiphase mixed transportation of liquid, gas, and solid.
🌊
When the fluid flows inside the pump, the volume does not change, and there is no turbulence, agitation, or pulsation.
🛡️
The volume cavity formed by the elastic stator can effectively reduce the wear of conveying media containing solid particles.
💧
The input dielectric viscosity can reach 5000MPa·S, and the solid content can reach 50%.
🔄
The pump can deliver forward and backward, and the flow rate is proportional to the speed.
Key Advantages
VS Centrifugal Pump: Does not need to install valves; flow is stable and linear.
VS Plunger Pump: Strong self-suction capacity and higher suction height.
VS Diaphragm Pump: Can transport mixed impurities containing gas, solid particles, or fiber media.
VS Gear Pump: Superior performance in transporting substances with extremely high viscosity.
Versatility: Can be used for reagent filling and precision metering.
Application Range
- Sewage treatment: Sewage, sewage oil, sludge with solids, and chemicals.
- Chemical industry: Acids, alkalis, salts, viscous pastes, dyes, and paints.
- Energy industry: Raw oil, crude oil, diesel, coal water slurry, and nuclear waste.
- Paper industry: Cellulose, pulp, coatings, and black liquor treatment.
- Ceramic Industry: Porcelain clay, glaze, bentonite, and refractory clay.
- Mining: Drilling mud, tunnel engineering, and concrete transportation.
- Food & Cosmetics: Syrups, jam, starch paste, alcohol, and chocolate.
Frequently Asked Questions
What types of fluids can this screw pump handle?
It can handle a wide range of fluids, including neutral or corrosive liquids, high or low viscosity media (up to 5000MPa·S), and fluids containing gas, fibers, or solid particles.
Does the pump support reversible operation?
Yes, the single screw pump is designed to deliver media in both forward and backward directions effectively.
How does it compare to a centrifugal pump regarding flow stability?
Unlike centrifugal pumps, the screw pump provides a stable, linear flow without the need for additional valves, preventing turbulence and pulsation.
Is the flow rate adjustable?
Yes, the flow rate is directly proportional to the rotation speed. Automatic quantity adjustment can be achieved using a speed governor.
Can it handle high solid content?
Absolutely. The pump can handle media with a solid content of up to 50%, and its elastic stator helps reduce wear from abrasive particles.
What industries is this pump suitable for?
It is widely used in sewage treatment, chemical processing, energy (oil/coal), paper manufacturing, ceramic production, mining, and the food/cosmetics industry.
