Recently, Tianjin Shuangjin Pump Industry Machinery Co., LTD., a leading domestic pump enterprise, has brought good news. Its independently developed HW type multiphase twin-screw pump, with its outstanding performance, has attracted widespread attention in the oilfield exploitation field, providing a brand-new solution for the upgrading of traditional crude oil transportation methods. This marks that China has entered the international advanced ranks in the research and development and manufacturing of multiphase pumps.
Established in 1981, Tianjin Shuangjin Pump Industry is one of the largest, most comprehensive in product range, and strongest in R&D and testing capabilities professional manufacturers in China’s pump industry. For many years, the company has been deeply engaged in fluid transportation technology, integrating design, development, production, sales and service. The HW type multiphase twin-screw pump launched this time is a concentrated demonstration of its technical strength. As the core equipment in the multiphase system, this multiphase pump breaks the limitation of traditional gas-bearing raw oil pump delivery that requires the separation of oil, water and gas. It does not need multiple liquid-gas pipelines, compressors or oil transfer pumps, greatly simplifying the mining process flow.
In terms of performance, the HW type multiphase pump has significant advantages. Its maximum capacity can reach 2000 cubic meters per hour, with a pressure difference of 5 megapascals and a GVF (Gas Volume Fraction) of 98%. Even if the inlet GVF changes rapidly between 0% and 100%, it can still operate stably. Meanwhile, the product adopts a dual suction configuration, which can automatically balance the axial force. The separated structure of the screw and the shaft effectively reduces maintenance and manufacturing costs. The specially designed bearing span and screw not only reduce screw scratches, extend the service life of seals and bearings, but also significantly enhance the efficiency and operational safety of the pump. In terms of sealing parts, single mechanical seals or specially designed double mechanical seals can be flexibly selected according to working conditions to meet the needs of different scenarios. In addition, this multiphase pump is strictly designed in accordance with API676 standards and has increased the allowable idling time. It has extremely strong adaptability and can be applied not only to onshore and offshore oil fields but also to surrounding oil fields. It can reduce wellhead pressure, increase crude oil production, and at the same time reduce base construction costs and extend the service life of oil Wells.
Relying on the dual advantages of introducing advanced foreign technologies and collaborating with domestic universities for research and development, Tianjin Shuangjin Pump Industry has obtained multiple national patents and has been recognized as a high-tech enterprise in Tianjin. Its products are widely used in numerous industries such as petroleum, chemical engineering and shipping, and are sold well in 29 provinces and autonomous regions across the country, with some even exported overseas. The launch of the HW type multiphase pump this time not only further enriches the company’s product line, but also will inject new vitality into the global oilfield exploitation industry and promote multiphase transportation technology to a higher level.
