    螺桿泵在啟動前應注意哪些事項
    發布者:  點擊:72

    螺桿泵是容積式轉子泵,它是依靠由螺桿和襯套形成的密封腔的容積變化來吸入和排出液體的。螺桿泵按螺桿數目分為單螺桿泵、雙、三和五螺桿泵。螺桿泵的特點是流量平穩、壓力脈動小、有自吸能力、噪聲低、效率高、壽命長、工作可靠;而其突出的優點是輸送介質時不形成渦流、對介質的粘性不敏感,可輸送高粘度介質。

    螺桿泵在啟動前應注意哪些事項:

    1、先確保吸入管路段和儀表接頭的連接是保持密封的。

    2、螺桿泵開始啟動或者長時間未啟動使用時,應先在吸入室中注滿介質,人工轉動泵軸數轉后再啟動。以防止定子和轉子間干摩擦,對定子造成損害或降低泵的吸入性能。

    3、單螺桿泵啟動前應先對泵的隔套層進行加熱,以降低泵內殘存介質的粘度。

    5、對泵的原動機轉向進行檢查,防止逆轉。

    6、啟動前要確保管內暢通,因此需將進口管路和出口管路上的閥門都打開。
