As a national high-tech enterprise, Tieling Dongsheng Petroleum Machinery Co., Ltd. has developed into an industry leader since its establishment, relying on years of technological precipitation. The company has a standardized production workshop of 12,000 square meters with an annual production capacity of more than 20,000 units. It has not only passed the ISO9001 quality management system certification, but is also one of the few domestic enterprises that have passed the API special certification. A number of independent patented technologies and a perfect quality inspection system allow Dongsheng insert pump to adapt to the harsh environment of oil and gas extraction and meet the complex needs of mining operations.
Insert pump shows unique advantages in mining: its rod-column transmission structure has been specially strengthened to withstand the continuous erosion of solid particles in the slurry, and its service life is extended by more than 30% compared to ordinary pump types. For the common high-viscosity ore slurry and sand-containing fluids in mining scenes, the flow channel of the pump body adopts a streamlined design to reduce the risk of clogging and increase the conveying efficiency by 15%.
Dongsheng's main insert pump series has its own focus: The RWA insert rod pump can effectively cope with acidic media in mining drainage by improving the sealing components and using corrosion-resistant alloy materials, and its performance is stable in the metal mine drainage system; The RWB insert rod pump strengthens the suction capacity and expands the diameter of the flow channel to 1.2 times that of conventional models. When processing high-concentration ore slurry, the flow attenuation rate is reduced by 20%, especially suitable for non-metallic ore slurry transportation; RWT insert rod pump is specially designed for deep well mining, the core components are treated with high temperature and high pressure, and can withstand 150℃ ambient temperature and 150℃ ambient temperature. The working pressure of 35MPa makes the deep mine drainage system operate continuously and trouble-free.
The maintenance characteristics of these insert pumps are particularly suitable for mining needs-they adopt a modular design, key components can be quickly replaced, and the single maintenance time is shortened to 1/3 of the traditional pump type, greatly reducing the impact of downtime. At the same time, it has strong adaptability. It can not only cooperate with the mobile operation of small mines, but also be integrated into the automated conveying system of large-scale mining. By adjusting the length of the column and the parameters of the pump body, it can meet the conveying requirements of different depths and different media.
Although centrifugal pumps have their own advantages in large-flow scenarios and submersible pumps in underwater operations, Dongsheng insert pump has formed a differentiated competitiveness in the mining field with its comprehensive performance of anti-wear, easy maintenance, and multi-scene adaptation. From surface slurry transportation to underground drainage system, Dongsheng Petroleum has always taken technological innovation as the core, continuously strengthened the adaptability of insert pump to working conditions, and provided efficient and stable fluid transportation solutions for the mining industry to help mining reduce costs and increase efficiency.
