第 一 題

📖 題組:
四、請以英文回答下列問題:(每小題 10 分,共 20 分) (一)What are the objectives to be accomplished for a main propulsion system? (二)There are two fundamental types of pumps, namely the kinetic type and the positive-displacement type. Please itemize the pumps characterized as the kinetic and the positive-displacement types.
📝 此題為申論題,共 2 小題

小題 (一)

What are the objectives to be accomplished for a main propulsion system?

思路引導 VIP

看到這題,首先要聯想到船舶主推進系統的核心物理功能:產生推力 (Thrust) 以提供船舶前進 (Ahead) 與倒車 (Astern) 的操縱能力。接著,從輪機長實務管理的角度切入,推進系統的目標還必須包含:高可靠度 (Reliability)、燃油經濟性 (Fuel efficiency) 以及符合國際海事環保法規 (Environmental compliance)。務必嚴格遵守題目『以英文作答』的要求,並使用精確的輪機英文術語。

【Introduction】 The fundamental purpose of a main propulsion system is to convert the energy from fuel into mechanical power to drive the ship. 【Core Objectives】

小題 (二)

There are two fundamental types of pumps, namely the kinetic type and the positive-displacement type. Please itemize the pumps characterized as the kinetic and the positive-displacement types.

思路引導 VIP

考生看到此題應立刻想到船用泵浦的兩大分類:動能型(依靠葉輪賦予流體動能)與容積型(依靠機械容積變化擠壓流體)。作答時,除了直接列出泵浦名稱,建議將容積型進一步細分為往復式(Reciprocating)與旋轉式(Rotary),並簡要補充各泵浦的實務應用,能展現更深厚的輪機英文與實務素養。

Pumps used in marine engineering can be broadly classified into two fundamental categories. The specific pumps characterized under the kinetic and positive-displacement types are itemized as follows:

  1. Kinetic Type Pumps: These pumps add kinetic energy to the fluid via a rotating impeller and convert it into pressure. They include:
