摘要/Abstract

摘要： 煤矿透水事故时有发生，现有抢险泵难以快速下井排水。为实现快速救援目标，提出一种新型体积小、流量大和扬程高的矿用高速抢险泵。机组设计采用上机下泵、机泵一体、独立冷却润滑回路、高速推力轴承机构以及水仓湿定子潜水电动机密封等关键技术。在同等流量、扬程的情况下，和现有产品相比，设计开发的矿用高速抢险泵在长度上减少了31%，重量减少了51.2%。以GFQ200-300型样机为例，通过数值模拟计算方法得出矿用高速抢险泵在6 000 r/min下，不同叶轮和导叶叶片数匹配模式下，最大扬程为304.56 m，最高效率为64.32%。样机试验结果表明：矿用高速抢险泵结构和水力设计合理，满足性能要求；数值模拟计算方法准确可靠，且采用SST k-ω模型最为贴近试验结果。样机整体机组结构和水力模型方案为后续大功率高速泵机组的设计提供了重要理论指导和技术积累。

Abstract: Nowadays, coal mine flooding accidents often happen. However, the existing rescue pump can't be quickly lowered into the well for drainage. To meet the requirement of rapid rescue, a new type of mine high speed rescue pump with small volume, large flow and high head is proposed. The whole structure is a combination of upper motor and lower pump. Besides, independent motor cooling and lubrication circuit, high speed thrust bearing and submersible sealing technology of wet stator are adopted in the unit. Under the same flow rate and head, the length and weight of the prototype are reduced by 31% and 51.2% compared with the pump in the current market. Taking the GFQ200-300 prototype as an example, the results of numerical simulation show that the maximum head is 304.56 m and the maximum efficiency is 64.32% at 6 000 r/min under different matching cases of the blade numbers of impeller and diffuser vane. From the experiment results, it is observed that the overall structure and hydraulic design of the prototype are reasonable and satisfactory; also, the accuracy of the numerical simulation calculation method is verified and the performance predicted used by SST k-ω model is the closest to the experiment data. Furthermore, the design scheme of the whole unit structure and hydraulic model could provide important theoretical guidance and technical reference for the subsequent design of big power and high speed pump units.
