Advantages and Characteristics of Lishen Single Screw Pump
The G-type single screw pump is a new type of pump that operates on the principle of rotary meshing volumetric displacement. Its main working components are the eccentric screw (rotor) and the fixed liner (stator). Due to the special geometric shapes of these two components, they form individual sealed cavities. The medium flows axially in a uniform manner, maintaining a low internal flow velocity with constant volume and stable pressure, thus avoiding the creation of vortices and turbulence. Each stage of the pump has an output pressure of 0.6MPa, a head of 60m (for clear water), and a self-priming height generally at 6m. It is suitable for conveying media with temperatures below 80℃ (up to 150℃ under special requirements).
Since the stator of the single screw pump is made from various elastic materials, this pump is capable of conveying high-viscosity fluids, as well as media containing hard suspended particles or fibrous materials—features that general pump types cannot match. Its flow rate is directly proportional to its speed.
Due to its structure and operational characteristics, the single screw pump has many advantages compared to piston pumps, centrifugal pumps, vane pumps, and gear pumps:
1. The single screw pump offers uniform flow and stable pressure, which is particularly evident at low speeds;
2. It can convey media with high solid content;
3. The pump can be installed at any inclined position;
4. Flow rate is directly proportional to the pump's speed, giving it excellent variable regulation properties, making it ideal for self-priming sewage pumps;
5. One pump can handle different viscosity media, making it multi-functional;
6. The single screw pump is compact, lightweight, quiet, with a simple structure that makes maintenance easy;
7. It is suitable for conveying sensitive items and items prone to damage by centrifugal force.
