Oil And Gas Drilling Head Decanter Centrifuges Single Screw Pump S.S, Alloy, Etc.

APG Screw pump consists of suction, discharge, working part (Rotor and Stator), driving part, universal joint part seal assembly, and bearing seat. The working part is composed of a rotating eccentric rotor and stator. The rotor and stator have two contact points in every transverse section. These contact points from two sealing lines along with the working parts of the rotor (or stator). Thus comes into one or a few sealing chambers when the rotor rotates. The media entering the sealing chamber remove smoothly from the suction end to the discharge end along with the sealing chamber. During the whole running, the pressure pulsation is very low, which does not affect the pumped media's intrinsic construction.

Single screw pumps are used widely to feel kinds of medium, running at a constant pressure continuously, without pulse and damage when feeding medium, and change the gauging aim through adjusting rotation speed.

Please check below technical specifications for your reference.

Screw pumps 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 with high-quality rubber. According to different fluids' content and property, we'll provide a certain configuration on screw pumps. For example, for the abrasive material, we kindly suggest using special rubber instead of stainless steel. As we know, the S.S can't adapt abrasive material but corrosive material. Compared to other pumps, the 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

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 with a 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 the 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 holding a capacity from 8m³/h-350m³/h. Besides the solids control system, a screw pump can be used in other applications, too. The centrifuge feeding pump is a rather typical use of a screw pump for the drilling mud process. Compared to other pumps, screw pumps holding shorter life or operation life considering the wearing parts. But it's a compact and high effect, many users prefer it then
