In the fluid transportation processes of industries such as petrochemicals, food, medicine, and environmental protection, traditional pump bodies often encounter problems such as leakage, blockage, and low efficiency when dealing with complex media containing high viscosity, particles, and volatility. The double helix rotor pump system, with its unique structural design and advanced fluid mechanics application, has become a core equipment for meeting the transportation demands of complex working conditions, providing a reliable guarantee for the continuous and stable operation of industrial production. The core competitiveness of this system stems from the precise meshing design of the twin-screw rotors. Two intermeshing screw rotors are adopted, and they are driven by synchronous gears to rotate in opposite directions, forming a closed cavity to smoothly convey the medium. The rotor adopts an involute tooth profile optimization design. After precise processing, the meshing clearance is controlled within 0.03mm. This not only ensures high sealing during the conveying process, preventing medium leakage and evaporation, but also effectively reduces operating noise. The overall operating noise of the machine is below 82dB (A). According to the characteristics of different media, the rotor can be made of stainless steel, wear-resistant alloy, fluoroplastic and other materials, suitable for fluids with a viscosity range of 1 to 100,000 mpa · s, and can easily handle the transportation of granular media with a solid content of ≤5%. Effective energy conservation and stable reliability are another major highlights of it. Compared with vane pumps and gear pumps, the volumetric efficiency of the double helix rotor pump system is as high as over 98%, the conveying pressure covers 0.6-4.0MPa, and the flow regulation range is as wide as 0.5-1000m³/h, meeting the production needs of different scales. Adopting non-pulsating conveying technology, the medium flow rate is uniform and stable, avoiding the impact of pressure fluctuations on subsequent processes. It is especially suitable for scenarios with extremely high requirements for conveying stability, such as precision chemicals and pharmaceutical preparations. Meanwhile, the pump body adopts a dry mechanical seal structure and is equipped with an independent lubrication system. The core components have a service life of up to 12,000 hours, and the maintenance cycle is 50% longer than that of traditional pump bodies, significantly reducing operation and maintenance
