為保證油泵的性能充分發(fā)揮和有個(gè)好的使用年限，在使用熱油泵時(shí)，應(yīng)該注意以下幾個(gè)方面：開機(jī)過程中，要時(shí)時(shí)注意電動(dòng)機(jī)的功率讀數(shù)及振動(dòng)情況，振動(dòng)值不超過.6毫米，如有異常應(yīng)停車檢查；打開相關(guān)儀表的開關(guān)；靠葉輪側(cè)的球軸承安裝時(shí)，熱油泵有防塵蓋的一側(cè)要朝向葉輪安裝，開車前注入導(dǎo)熱油潤滑；剛開始運(yùn)行時(shí)，把生產(chǎn)流程中的設(shè)備緩緩加熱到1-13度，熱油泵并且保持在該溫度下繼續(xù)運(yùn)行，脫水脫氣到導(dǎo)熱油中的水份完全蒸發(fā)，才把設(shè)備加熱到操作溫度；在運(yùn)行中的前3-4小時(shí)，把設(shè)備加熱到操作溫度之后關(guān)掉油泵，檢查泵軸和電機(jī)軸聯(lián)軸器的同軸度，泵軸和電機(jī)軸偏差應(yīng)控制在允許范圍內(nèi)，泵軸用手轉(zhuǎn)動(dòng)應(yīng)輕便靈活和無振動(dòng)旋轉(zhuǎn)，熱油泵如達(dá)不到上述要求，應(yīng)重新進(jìn)行調(diào)整；靠聯(lián)軸器側(cè)的球軸承，用復(fù)合鈣基高溫潤滑脂，該軸承重新安裝時(shí)，熱油泵有防塵蓋的一側(cè)同樣要朝向葉輪側(cè)安裝，安裝時(shí)充填潤滑脂；接通電源，當(dāng)泵達(dá)到正常轉(zhuǎn)速，且儀表顯示出相當(dāng)壓力后，逐漸打開輸出管路上的閘閥，并調(diào)節(jié)到需要工況。

上世紀(jì)全球因地震死亡12萬人，其中死亡6萬人。近兩年我國汶川8級(jí)地震死亡7萬人，智利8.8級(jí)地震死亡7人，新西蘭7.2級(jí)地震零死亡。這些事故都與鋼材質(zhì)量有一定關(guān)系。我國風(fēng)力發(fā)電機(jī)用齒輪、軸承，雖然轉(zhuǎn)速不高，不是高、精、尖產(chǎn)品，但它們是在荒漠、高原或海域8米以上高空運(yùn)行，很難維修，壞一個(gè)小零件等于報(bào)廢整臺(tái)機(jī)組。風(fēng)電設(shè)備要求鋼材質(zhì)量必須百分之百穩(wěn)定和均一，保證2年不維修。但國產(chǎn)鋼材質(zhì)量不穩(wěn)定，用戶不敢采用，基本靠進(jìn)口。

不同正極材料具有不同的三維結(jié)構(gòu)，目前用作電動(dòng)汽車動(dòng)力電池的正極材料主要是磷酸鐵鋰、鎳鈷錳三元材料和錳酸鋰。吳文迪等研究了磷酸亞鐵鋰電池與鎳鈷錳三元電池在－2℃的放電性能，發(fā)現(xiàn)磷酸鐵鋰電池在－2℃的放電容量只能達(dá)到常溫容量的67.38％，而鎳鈷錳三元電池能夠達(dá)到7.1％。杜曉莉等發(fā)現(xiàn)錳酸鋰電池在－2℃的放電容量可以達(dá)到常溫容量的83％。高熔點(diǎn)溶劑由于電解液混合溶劑中存在高熔點(diǎn)溶劑，鋰離子電池電解液在低溫環(huán)境下黏度增大，當(dāng)溫度過低時(shí)會(huì)發(fā)生電解液凝固現(xiàn)象，導(dǎo)致鋰離子在電解液中傳輸速率降低。
