Startup Success of Highest-pressure Tailings Transfer Pump

重泵成功试车国内压力最高尾矿输送用矿浆泵
Startup Success of Highest-pressure Tailings Transfer Pump

 4月6日,用于管道输送的高压矿浆隔膜泵机组（流量280m3/h,压力16Mpa）在重泵重装车间一次性试车成功，并于近日发货。这标志着被西方垄断的高压矿浆泵在重泵研制成功。

On April 6, the high-pressure slurry diaphragm pump unit for pipeline transportation (flow 280M3/ h, pressure 16MPa) passed startup tests in CQPI’s Heavy Workshop at one time, delivered to project onsite recently. This marks successful localized development of high-pressure slurry pump at CQPI, which has long been monopolized by the West in past.

中铝集团某尾矿输送项目是国内压力最高的尾矿输送管道，矿浆泵是该项目的核心设备，直接关系着后续铝土矿资源接替利用。重泵承接该项目合同后，研发工程师们勇挑重担，攻克多项技术难关，最终实现成功国产化。

This tailing conveying project is from Chinalco group, and it is the tailings conveying pipeline with the highest pressure so far in China. The slurry pump is the core equipment of the project, which is directly related to the subsequent replacement and utilization of bauxite resources. After contract awarded, CQPI engineers have bravely shouldered tough task to overcome numerous technical difficulties, finally achieving successful localization.

重泵技术团队在该项目自主开发出高承压型液力端技术、整体重载动力端箱体铸造技术、智能电磁补排油技术、应用了机组同步等技术。试车试验数据显示，泵组流量和压力不仅达到了设计要求，而且机组效率达90%以上，出口脉动小于±0.5%，高于国外设备出口脉动±1%～±2%的标准，其技术指标已达到国际先进水平。

In this project, CQPI engineering team independently developed technology of high-pressure hydraulic end, technology of compact heavy-duty power end box casting, technology of intelligent electromagnetic oil supplement and drainage, and technology of pump unit synchronization. The commissioning test data shows that the flow and pressure of the pump unit not only meet the design requirements, but also the pump unit efficiency is over 90%, the outlet pulsation is less than ± 0.5%, which is higher than western standard of ±1%～±2% in terms of outlet pulsation, and its technical value indicators have reached advanced international level.

随着中国碳中和、碳达峰和绿色矿山战略的持续推进，长距离管输将成为矿冶生产中最主要的矿浆运输方式。重泵有望为更多本地项目提供矿用隔膜泵产品和服务。

With China’s continuous strategy promotion of carbon neutralization, carbon peak and green mine, the long-distance pipeline transportation will become a most important slurry transfer mode in the area of mining and metallurgical production. (Source-CQPI; English-YYG)
