離心泵在使用過程中常見故障一般有,軸承噪音大軸承發(fā)熱:(軸承老化,潤滑油太臟、更換軸承和潤滑油)
Centrifugalpumpintheuseofcommonfaults,bearingnoiselargebearingheating:(bearingaging,lubricatingoiltoodirty,changingbearingsandlubricants).
上量不穩(wěn)定:葉輪口環(huán)間隙過大、(更換口環(huán))葉輪流道堵塞、(清理流道雜質(zhì))泵抽空、(檢查液位、重新灌泵排氣)吸入管線堵塞或漏氣、(檢查吸入管線)介質(zhì)溫度過高氣化(降溫冷卻后重新排氣灌泵)。

泵體振動過大:泵發(fā)生氣蝕抽空(排除)軸承老化(更換)聯(lián)軸器對中不良(重新校正)地腳螺栓或各連接螺栓有松動(檢查擰緊)
Pump body vibration too large: pump cavitation and evacuation (removal) bearing aging (replacement) shaft coupling for bad (rectified) anchor bolts or joint bolts loosening (check tightening)
