給水器
Appearance
給水器是蒸汽機車 上用於將儲有 的水注向鍋爐 ,維持正常水位 的設備。通常透過一個閥門進行操作。
自煤水車中注入鍋爐中的水的尚未加熱,它會影響鍋爐中的既有水溫。因此,建議根據所消耗水量緩慢且連續地注入所須水量,以免過度干擾蒸汽的產生。水溫並無法直接監控,只能透過觀察壓力表指針的移動速度間接進行推斷。
There is no way to monitor water temperature, other than indirectly by looking at the speed the boiler pressure gauge needle is moving.
Injectors normally rely on steam pressure to inject water, but in Derail Valley this limitation is omitted to avoid complications when starting a cold engine.
