Single screw pump is widely used in petroleum drilling industry
Dec 06, 2021
Single screw pumps have been widely used in developed countries, and most foreign countries call single screw pumps "Monopumps" (MONOPUMPS). Due to its excellent performance, the scope of applications has also been rapidly expanding in recent years. The biggest feature of the pump is strong adaptability to the medium, stable flow, small pressure pulsation, and high self-priming ability, which cannot be replaced by any other pump type.
The single screw pump is a new type of pump that works according to the principle of revolving meshing volumetric type. The main working parts are eccentric screw (rotor) and fixed bushing (stator). Due to the special geometric shapes of the two parts, separate sealed cavities are formed respectively. The medium flows uniformly in the axial direction, the internal flow rate is low, the volume remains unchanged, and the pressure is stable, so there is no vortex and agitation. The output pressure of each stage pump is 0.6MPa, the head is 60m (clear water), and the self-priming height is generally above 6m.
The transmission can be directly driven by a coupling, or variable speed by high-speed motors, V-belts, gearboxes and other devices. G type screw pump has few parts, compact structure, small size, simple maintenance, rotor and stator are the vulnerable parts of the pump, simple structure, easy to assemble and disassemble. Because the stator is made of a variety of elastic materials, this kind of pump has the advantage of conveying high-viscosity fluids and conveying media containing hard suspended particles or media containing fibers that cannot be matched by general pumps. Its flow rate is proportional to the speed.
