    摘要:

    采用閉式流體輸送試驗臺，對具有前置誘導輪的高速離心泵進行了汽蝕特性試驗研究，比較分析了無誘導輪、單個及串聯(lián)誘導輪3種工況下誘導輪對離心泵性能及汽蝕性能的影響。發(fā)現(xiàn)前置單個或串聯(lián)誘導輪對離心泵的性能影響并不顯著，單個誘導輪的離心泵性能相對于無誘導輪的離心泵性能稍有下降，具有串聯(lián)誘導輪的離心泵揚程和效率與無誘導輪離心泵相比稍有增加；但采用串聯(lián)誘導輪可有效提高離心泵的汽蝕性能。

    Abstract:

    Experimental research on suction performance was carried out on high-speed centrifugal pump with inducer by using closed test. The effect on the characteristic and suction performance of the centrifugal pump was analyzed with no inducer, one and two-phase inducers. It was found that one or two-phase inducers had little influence on the characteristic performance of a centrifugal pump. Compared with no inducer, the head and efficiency decreased slightly by using one inducer, and they slightly increased by using a two-phase inducer. But suction performance of centrifugal pump was improved by using a two-phase inducer.
