[". 双螺杆 泵의 异响

2019-03-16View Original

Thread Content

우리는 원유 储运区에 있습니다. 여기서 두 台의 66m3/h의 双螺杆 泵가 있습니다. 우리는 생산作业时发现这两台 泵经过长时间运转后,齿轮箱处发出 异响,声音较大。检查各处 压力、温度均无异常。同时在生产期间输出量明显不足。出现以上情况个人认为是 泵轴的原因,输出量可能是油品理化性质粘度大导致 泵抽空的原因。烦请大家帮忙讨论。

三. 泵抽空的声音来自 泵体,齿轮箱处发出 异响应该是 齿轮或者轴承的问题声音明显不同。动设备如果出现声音变化就要及时处理。

四. 容积式 泵汽蚀也会产生撞击样的 异响。油品温度高同时油品中含水等组分,泵吸入时汽化排出时由于压力高又液化压力有瞬间变低所以会有液击样撞击声。推荐考虑检查油品组分。

五. 压力无异常却明显量不足?似乎有点矛盾齿轮异响应该不会影响到量无还是从逐步排查考虑一下是否堵塞角度。

六. 作业输出量不足说明有气阻齿轮噪音是由于螺杆泵流量不稳有脉动造成齿轮异响应及时排气排查工艺长期运行齿轮磨损螺杆撞击
