葉輪和密封件需要定期檢查。 葉輪的使用壽命有限。 使用壽命取決於引擎的作業條件。

當泵接觸到碎屑、砂或其他磨蝕性物質,請更頻繁地檢查組件。 若泵以高於 103 kPa (15 psi) 的差速器壓力運作,請檢查組件。

泵有各種不同類型。 某些泵的外蓋會用螺栓固定至主泵體。 某些泵則會用固定夾將泵體前部固定至泵體主要部分。 若要檢查泵,您必須取下外蓋或泵體前部。

含外蓋的泵

    (1) 塞子
    (2) 螺栓
    (3) 頂蓋

  1. 取下塞子 (1) 並將泵中的水排空。

  2. 取下螺栓 (2) 與外蓋 (3)。

  3. 檢查充油葉輪、充油葉輪的耐磨板及葉輪是否有磨損或損壞情形。 檢查泵外殼是否有磨損、損壞或聚積物。

  4. 檢查泵軸和葉輪是否過度軸向移動。

  5. 若發現磨損或損壞,請更換磨損或損壞的組件。 使用適當的維修套件修理水泵。

  2. 如有必要,請取下水管和固定夾 (2)。

  3. 鬆開固定夾 (3),然後卸下泵體的前部 (4)。

  4. 檢查葉輪、耐磨板及耐磨環是否有磨損或損壞情形。 檢查泵外殼是否有磨損、損壞或聚積物。

  5. 檢查泵軸和葉輪是否過度軸向移動。

  6. 若發現磨損或損壞,請更換磨損或損壞的組件。 使用適當的維修套件修理水泵。
