同時(shí)泵的效率根據(jù)泵的大小而不同，通常來(lái)講大泵會(huì)比小泵效率更高。當(dāng)泵的速度改變時(shí)，泵的效率將同時(shí)改變。如果速度降低小于2％，效率的改變很小。雖然總效率對(duì)能耗來(lái)講是很重要的，但控制模式卻對(duì)能耗有著更大的影響。下圖展示了不同控制模式下的節(jié)能效果：四：結(jié)論：隨著技術(shù)的進(jìn)步，變頻技術(shù)將越來(lái)越多的被人們認(rèn)可和應(yīng)用，配合正確的系統(tǒng)設(shè)計(jì)（如三次泵系統(tǒng)）以及科學(xué)的選泵配泵，在使用戶感受到更高舒適性的同時(shí)，得到更加明顯的節(jié)能效果。

保溫時(shí)間過(guò)長(zhǎng)，也會(huì)也出現(xiàn)晶粒粗大，氧化脫碳嚴(yán)重的弊病，影響淬火質(zhì)量。我們認(rèn)為，如裝爐量大于工藝文件的規(guī)定，加熱保溫時(shí)間需延長(zhǎng)1/5。因?yàn)?5號(hào)鋼淬透性低，故應(yīng)采用冷卻速度大的1％鹽水溶液。工件入水后，應(yīng)該淬透，但不是冷透，如果工件在鹽水中冷透，就有可能使工件開(kāi)裂，這是因?yàn)楫?dāng)工件冷卻到18℃左右時(shí)，奧氏體迅速轉(zhuǎn)變?yōu)轳R氏體造成過(guò)大的組織應(yīng)力所致。當(dāng)淬火工件快冷到該溫度區(qū)域，就應(yīng)采取緩冷的方法。
