Sumary of screw pump

A screw pump is a rotary pump which is a form of a positive displacement pump and it delivers a known quantity of fluid for every revolution.

A screw pump is made up of various components such as; a casing, a screw (depending on the type of screw pump; it can contain 1 screw up to 5 screws), bearings, a seal, a motor adapter and a drive shaft. Screw pumps are quite simple in construction.

Screw Pump Technical Parameters

How does a screw pump work?

The screw pump, as the name implies, the form of the screw is similar to a screw thread and hence by rotating it, the fluid moves along the screw thread from the suction side to the discharge side of the pump. Due to very close clearances inside the pump, the volumetric efficiency is high especially with viscous fluids as this reduces the amount of slippage of the fluid from the high pressure to the low pressure side. The pump itself like any positive displacement pump does not produce pressure, it only moves fluid but it is the actual system which produces back pressure due to friction loss.

What are the applications and uses of screw pumps?

Screw pumps are mostly used on fluids of a higher viscosity, moving these fluids with screw pumps results in energy efficient and a relatively compact machine when compared to other pump types i.e centrifugal pump. For screw pumps with more than 2 screws, they are normally used on lubricating fluids only because the screws are not geared together and are relying on the fluid to lubricate the screws.

With a twin screw pump, the screws are geared which prevent the screws contacting each other and can therefore be used on non-lubricating fluids, chemicals and food-stuffs etc Twin screw pumps are capable of a higher flow rate than higher screw pump types i.e more than 2 screws.

The main applications for a screw pump are oil based fluids, tar bitumen, adhesives (industrial type), chemicals and dairy products.

Application of screw pump

Screw pump mainly consisted of the discharge port, the stator, the rotor, the flexible section, the middle axis, suction room, seal, bearing, driveshaft, bearing body. Among these parts, the wearing parts are the rotor and stator. The screw pump wet parts can be made of stainless, steel, and the high quality rubber. According to different fluids' content and property, we'll provide a certain configuration on screw pumps. For example, the abrasive material we kindly suggest use the special rubber instead of stainless steel. As we know, the S.S can't adapt abrasive material but corrosive material. Compared to other pumps, screw pump is not easy to lead swirl. This helps much to maintain pump capacity. It is not sensitive to viscosity so it is capable to transfer material with high viscosity

Aipu screw Pump features

• Medium is delivered continuously without agitation and pulsation.

• Small vibration and low noise.

• High pressure and high efficiency.

• Simple structure and easy assemble.

• Small volume and lightweight.

• Wearable and long life.

Actually, when the screw axis is rotating, the lower Vroom will become large. Vroom will close against fluid sucked. The closed room will be pushed forward along the axle. Then a new suction cavity generates on suction end. One and one closed cavity move forward, the fluid will be pressed out.
