Rotary Rotor Screw Pump For Offshore Platform Positive Displacement

Screw Pump Rotor Rotary Pumps For Offshore Platform Positive Displacement

Single Screw Pumps are a type of Positive Displacement Pumps. These pumps work on the principle of the rotary movement of a single helix metallic rotor inside a double helix elastomer stator. When the rotor starts to move inside the stator, the cavities are formed resulting in the positive displacement of liquid through cavities. The liquid is then released from the discharge side of the pump.
Single Screw Pumps are best suitable for applications needing a non-pulsating and uniform flow. These pumps ensure a high suction-lift and can transfer tough to handle fluids having solids, highly viscous, abrasive elements, etc. These pumps are actively used to handle sewage, bilge, sludge, and even food items like jam, starch, and butter. These pumps are used in processing and manufacturing plants of various industries such as marine, chemical, cosmetics, paint, wastewater, oil & gas, and many more. Single screw pumps are non-clogging and can be operated in reverse condition as well. These pumps are also extremely easy to maintain.

Single Rotor Rotary Pumps. Flexible member – Flexing vanes are used to move media. Pumping and sealing is dependent on the elasticity of these flexible vanes. They can also be a tube or liner. Peristaltic – A flexible tube inside a circular casing is usually used, although there are linear peristaltic pumps.

Screw pump transfer drilling fluid via the screw conveyor rotation. The Center screw pole is the positive pole, the two sides screw conveyor is the negative pole. Negative poles rotate in the opposite direction from the positive pole.

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 the suction end. One and one closed cavity move forward, the fluid will be pressed out.

How to select a screw pump? Yes. It's depending on the centrifuge flow rate request. The screw pump APG series holds a capacity from 8m³/h-350m³/h. Besides the solids control system, a screw pump can be used in other applications, too. For the drilling mud process, the centrifuge feeding pump is a rather typical use of a screw pump. Compared to other pumps, a screw pumps holds shorter life or operation life considering the wearing parts. But it's a compact and high effect, many users prefer it then
