1、 Overview of G-type gear variable speed screw pump products

Single screw pump is a new type of pump that works according to the principle of rotary meshing displacement. The main working components are eccentric screw (rotor) and fixed liner (stator).

Due to the special geometric shape of these two components, they form separate sealed chambers, and the medium flows uniformly in the axial direction. The internal flow velocity is low, the volume remains constant, and the pressure is stable, so there will be no vortex or agitation. The output pressure of each stage pump is 0.6MPa, the head is 60m (for clean water), and the self-priming height is generally 6m. It is suitable for conveying medium temperatures below 80 ℃ (special requirements can reach 150 ℃). Due to the selection of multiple elastic materials for the stator, this pump has characteristics that general pump types cannot handle for transporting high viscosity fluids and media containing hard suspended particles or fiber media. Its flow rate is proportional to the rotational speed. Transmission can be achieved directly through couplings, or through devices such as variable speed motors, V-belts, gearboxes, etc. This type of pump has few parts, compact structure, small volume, and easy maintenance. The rotor and stator are the vulnerable parts of this pump, and the structure is simple and easy to assemble and disassemble.
