Screw pump

Release time: 2015/10 / 15Views of solid control equipment : 7045

In drilling solid control systems, screw pumps are generally used with drilling fluid centrifuges and are single screw pumps.

Overview of the screw pump: compact structure, simple maintenance, simple structure, easy assembly and disassembly, small size, small pressure pulsation, strong adaptability to the medium, and working temperature up to 150 ° C. Due to the special geometric shapes of the two parts, G-type single screw pumps form separate sealed chambers. The medium flows uniformly from the axial direction, the internal flow rate is low, the volume remains unchanged, and the pressure is stable, so no vortex and agitation are generated. 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.
Because the stator of the screw pump is made of a variety of elastic materials, this pump has the characteristics that ordinary pumps cannot perform for the transportation of high-viscosity fluids and the transportation of media containing hard suspended particles or fibers. Its flow rate is proportional to the speed.
Screw pumps are compact in structure, small in size, and easy to maintain. Strong adaptability to medium, stable flow, small pressure pulsation, high self-priming ability. The working temperature can reach 120 ℃, if you need to transport high temperature medium between 120 ℃ -350 ℃, it can be customized. Widely used in food, metallurgy, papermaking, printing and dyeing, chemical, fertilizer, pharmaceutical and other industrial sectors.
