| 北京世聯翻譯公司資深譯員整理發布的有關機械操作指導翻譯 Operating Guidelines 譯：操作指導 Following these helpful guidelines will assure longer life for your vertical pump. 譯：遵守下述這些操作指導可以保證您的立式泵更長的使用壽命。 a. In order to operate, the bowl assembly must be submerged. Additional submergence may be required depending upon pump size and operating conditions. If in doubt, refer to the Engineering Department, XXX Pumps Inc.. 譯：為了操作，泵轉缽體組件必須潛入液體介質當中。其它潛入要求可以根據泵的規格和操作條件確定。如果有任何疑問，可咨詢XXX泵業公司的工程部。 b. Should the pump lose its prime, shut it down. DO NOT RUN IT DRY. The impellers and bearings, which hove small clearances, are apt to bind and cause serious trouble. 譯：如果泵內失去初給的起動液體介質，關閉泵，不允許泵的干運行。因為小間隙的葉片和軸承可能抱死并導致嚴重的故障。 c. It is better to throttle a pump if the capacity is too great for the supply rather than let it break suction or cavitate. 譯：如果泵的容量過大，最好對泵進行節流調節，而不致于使其失去抽吸能力或出現氣穴現象。 d. When the pump is stopped, the reverse flow of liquid through the pump will cause it to rotate backward if the unit is not equipped with a discharge check valve. If power is supplied at this time it places a severe strain on the shafting, which may break or result in other damage. Always allow the unit to stop completely before restarting. 譯：當停泵時，如果泵上沒有裝配止回閥，那么液體介質反向流過泵會導致反向旋轉。如果此時泵加電，那么將在軸系產生嚴重的應力，這樣會使軸斷裂或導致其它損壞。在重新啟動之前必須總是保證泵組完全停止。 e. Never let the discharge pipe be supported entirely by the discharge head. Concrete or steel structures should be the principal support. 譯：絕不允許由泵的排放端完全支撐排放管。主要由混凝土或鋼結構進行支撐。 |
