G-type gearbox reduction screw pump

1、 Overview of G gear variable speed screw pump

The single screw pump is a new type of pump that works according to the principle of rotary engagement volumetric type. Its main working components are eccentric screw (rotor) and fixed bushing (stator).

Due to the special geometric shape of the two components, separate sealed chambers are formed respectively. 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 will occur. The output pressure of each stage of pump is 0.6MPa, the head is 60m (clean water), the self-priming height is generally 6m, and it is suitable for conveying medium temperature below 80 ℃ (special requirements can reach 150 ℃). Since the stator is made of a variety of elastic materials, this pump is not competent for the transportation of high viscosity fluid and medium containing hard suspended particles or fiber. Its flow is proportional to the speed. The transmission can be directly driven by coupling, or speed regulating motor, V-belt, gearbox and other devices can be used for speed change. This kind of pump has fewer parts, compact structure, small volume, and simple maintenance. The rotor and stator are vulnerable parts of the pump, with simple structure and easy assembly and disassembly.
