Features
Working principle: The G-type single screw pump belongs to the rotary volumetric pump, which relies on the engagement between the screw and the bushing to create volume changes in the suction and discharge chambers to transport liquids. The main working components consist of a bushing (stator) with a double-headed helical cavity and a single-headed helical screw (rotor) that engages with it in the stator cavity. When the input shaft drives the rotor to perform planetary rotation around the center of the stator through a universal joint, the stator-rotor pair continuously engages to form a sealed chamber, and these sealed chambers move axially at a constant speed, transporting the conveyed medium from the suction end through the stator-rotor pair to the discharge end.
Compact structure: The design of the G-type single screw pump makes it compact, easy to maintain and clean. The layout of the pump body, screw, and other components is reasonable, occupying a small area, making it convenient to install and use in limited spaces.
Wear-resistant and corrosion-resistant: The stator is usually made of various elastic materials, which makes the pump perform well when transporting high-viscosity fluids and media containing hard suspended particles, making it less prone to wear while having good corrosion resistance.
Advantages
Wide medium adaptability: The G-type single screw pump can transport media with various viscosity ranges, from low viscosity to high viscosity liquids, including media containing solid particles, abrasive substances, and fibers. Its special helical design makes the pump less prone to clogging during the transport process and insensitive to impurities in the medium.
Stable pressure output: The pump's pressure can automatically adjust with changes in the resistance of the output pipeline, thereby maintaining a stable output pressure. This characteristic gives the G-type single screw pump a significant advantage in situations requiring constant pressure output.
Uniform flow characteristics: Due to the continuous rotation of the screw and the uniform motion of the chambers, the G-type single screw pump can provide very uniform flow. This makes it perform excellently in processes that require precise flow control.
Low speed and high torque: The G-type single screw pump typically operates at lower speeds but can generate higher torque. This design helps reduce wear and noise of the pump and extends its service life.
Strong self-priming ability: Some G-type single screw pumps are designed with good self-priming ability, capable of drawing in liquid without external auxiliary equipment. This feature makes the pump more flexible and reliable during startup and operation.
Low noise operation: Due to the structural design and operating principle of the pump, the noise generated during the operation of the G-type single screw pump is relatively low. This makes it more advantageous in situations requiring a low-noise environment.
Easy maintenance: The maintenance of the G-type single screw pump is relatively simple, requiring only regular checks of the pump body’s working condition and the wear of the screw, and timely replacement of worn parts. In daily use, it only requires cleaning and drying of the pump body, avoiding metal collisions and severe vibrations.
Versatility: The G-type single screw pump can not only transport liquids but also be used for functions such as dosing and filling. This makes it widely used in multiple industrial fields.
Applications
The G-type single screw pump, with its above characteristics and advantages, has been widely used in various industrial fields. For example:
Petrochemical industry: Used for the transportation of various oils, fats, chemicals, and other materials.
Pharmaceutical industry: While transporting, it reduces the contact of materials with air, avoiding contamination and oxidation, improving the quality and safety of medicines.
Food industry: Used for the transportation of various food raw materials, additives, and other materials, meeting the very high hygiene requirements.
Environmental protection industry: Used for the transportation and discharge of various waste liquids and sewage.
