加熱蓄電池室或把蓄電池存放在較溫暖的地方。

用跨接電纜起動(dòng)發(fā)動(dòng)機(jī),斯堪尼亞發(fā)電機(jī)組,斯堪尼亞發(fā)電機(jī)組維修,斯堪尼亞柴油發(fā)電機(jī)組維修,寧波斯堪尼亞柴油發(fā)電機(jī)組維修,浙江斯堪尼亞柴油發(fā)電機(jī)組維修,斯堪尼亞柴油發(fā)電機(jī)組維修保養(yǎng),斯堪尼亞柴油發(fā)電機(jī)組維修報(bào)價(jià),當(dāng)使用外部電源起動(dòng)發(fā)動(dòng)機(jī)時(shí)，只能使用電壓與起動(dòng)馬達(dá)的額定電壓相同的電源。

使用更高的電源電壓或電焊機(jī)的輸出電壓會(huì)損壞發(fā)動(dòng)機(jī)的電氣系統(tǒng)。 電源沖擊會(huì)導(dǎo)致發(fā)動(dòng)機(jī)電子控制模塊的損壞。

最好是使用一組備用的蓄電池，不推薦使用外部電源來(lái)起動(dòng)發(fā)動(dòng)機(jī) 。

發(fā)動(dòng)機(jī)起動(dòng)后

暖機(jī)

       1.　在提高發(fā)動(dòng)機(jī)轉(zhuǎn)速到額定轉(zhuǎn)速前， 讓發(fā)動(dòng)機(jī)在      低怠速下運(yùn)轉(zhuǎn)2到3分鐘，以使缸套水溫開(kāi)始上升。

       2. 　在暖機(jī)期間，檢查所有儀表上的讀數(shù)。

       3. 　再一次圍繞發(fā)動(dòng)機(jī)進(jìn)行檢查 ，檢查發(fā)動(dòng)機(jī)有無(wú)液體和空氣泄漏。

       注意：當(dāng)發(fā)動(dòng)機(jī)在額定轉(zhuǎn)速和小負(fù)荷下運(yùn)轉(zhuǎn)時(shí)，將較快地達(dá)到正常工作溫度。

接合被驅(qū)動(dòng)設(shè)備

1. 確保各種儀表都處于相應(yīng)發(fā)動(dòng)機(jī)轉(zhuǎn)速的正常范圍內(nèi)。

2. 增加發(fā)動(dòng)機(jī)轉(zhuǎn)速到額定轉(zhuǎn)速。在加負(fù)荷以前，必須將發(fā)動(dòng)機(jī)轉(zhuǎn)速增加到額定轉(zhuǎn)速。

3.    接合離合器以給發(fā)動(dòng)機(jī)加負(fù)荷。

4. 繼續(xù)檢查所有儀表的讀數(shù)和被驅(qū)動(dòng)設(shè)備。

儀表

當(dāng)發(fā)動(dòng)機(jī)在運(yùn)轉(zhuǎn)時(shí)，要頻繁地觀察儀表。

定期地將儀表上的數(shù)據(jù)記錄下來(lái) 。

將記錄下來(lái)的數(shù)據(jù)與標(biāo)準(zhǔn)數(shù)據(jù)相比較，以確保發(fā)動(dòng)機(jī)在正常運(yùn)轉(zhuǎn)。 比較這些數(shù)據(jù)有助于知道發(fā)動(dòng)機(jī)性能的變化。

確定并糾正儀表上任何明顯的讀數(shù)變化。

部分負(fù)荷運(yùn)轉(zhuǎn)

延長(zhǎng)在低怠速或較少負(fù)荷下的運(yùn)轉(zhuǎn)時(shí)間會(huì)引起機(jī)油消耗量的增加和氣缸中積炭。

積炭會(huì)造成功率損失和性能變壞。

如有可能，至少每小時(shí)加滿負(fù)荷運(yùn)轉(zhuǎn)一次，這樣能燒掉氣缸中過(guò)多的積炭。

警報(bào)器和停機(jī)裝置

為防止發(fā)動(dòng)機(jī)損壞，警報(bào)器和停機(jī)裝置都設(shè)定在臨界工作溫度、壓力或轉(zhuǎn)速下。

當(dāng)出現(xiàn)不正常的工作狀況時(shí)，警報(bào)器報(bào)警，以警告操作者。

當(dāng)出現(xiàn)更危急的不正常工作狀況時(shí)，停機(jī)裝置起作用，停止發(fā)動(dòng)機(jī)的運(yùn)轉(zhuǎn)。

停機(jī)裝置有助于防止設(shè)備的損壞。

       如果一種發(fā)動(dòng)機(jī)保護(hù)裝置使發(fā)動(dòng)機(jī)停機(jī)，則必須確定停機(jī)的原因。在再次起動(dòng)發(fā)動(dòng)機(jī)之前，進(jìn)行必要的修理。

       應(yīng)熟悉下列項(xiàng)目：

警報(bào)器和停機(jī)裝置的類型

警報(bào)器和停機(jī)裝置的位置

使各種保護(hù)裝置起作用的各種工作狀態(tài)

起動(dòng)發(fā)動(dòng)機(jī)之前所需的復(fù)位步驟

手動(dòng)停機(jī)

在發(fā)動(dòng)機(jī)停機(jī)前，應(yīng)使其逐漸冷卻。

發(fā)動(dòng)機(jī)已在負(fù)荷下運(yùn)轉(zhuǎn)后，立即使發(fā)動(dòng)機(jī)停機(jī)會(huì)造成過(guò)熱和發(fā)動(dòng)機(jī)零部件的加速磨損。

渦輪增壓器中心殼體中的過(guò)高溫度會(huì)造成機(jī)油焦化問(wèn)題。

使用以下的步驟作為發(fā)動(dòng)機(jī)的一般停機(jī)程序：

1.  脫開(kāi)發(fā)動(dòng)機(jī)與被驅(qū)動(dòng)設(shè)備之間的離合器

2.  在使發(fā)動(dòng)機(jī)停機(jī)前，讓發(fā)動(dòng)機(jī)有一段時(shí)間冷卻：

a. 如果啟用了發(fā)動(dòng)機(jī)的冷機(jī)功能，則把發(fā)動(dòng)機(jī)控制開(kāi)關(guān)轉(zhuǎn)到“冷機(jī)/停機(jī)”（COOLDOWN/STOP） 位置。

b.如果沒(méi)有啟用發(fā)動(dòng)機(jī)的冷機(jī)功能， 則讓發(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)在高怠速大約五分鐘，然后再讓發(fā)動(dòng)機(jī)停機(jī)。

3.  把發(fā)動(dòng)機(jī)控制開(kāi)關(guān)轉(zhuǎn)到“關(guān)機(jī)/復(fù)位” （OFF/RESET）位置。

自動(dòng)停機(jī)

當(dāng)發(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)在自動(dòng)模式而遠(yuǎn)程起動(dòng)/停機(jī)觸點(diǎn)斷開(kāi)時(shí)，將出現(xiàn)自動(dòng)停機(jī)。

如果發(fā)動(dòng)機(jī)啟用冷機(jī)功能，那么發(fā)動(dòng)機(jī)在停機(jī)前將按設(shè)定的時(shí)間冷機(jī)，然后停機(jī)。否則，發(fā)動(dòng)機(jī)會(huì)立即停機(jī)。

緊急停機(jī)

       緊急停機(jī)裝置僅用于 緊急情況。 正常停機(jī)不要使用緊急停機(jī)裝置。

發(fā)動(dòng)機(jī)正常運(yùn)轉(zhuǎn)時(shí)，緊急停機(jī)按鈕在“突起”位置。

當(dāng)需要緊急停機(jī)時(shí)，按下緊急停機(jī)按鈕。這會(huì)切斷發(fā)動(dòng)機(jī)的燃油供應(yīng)。 這同時(shí)也會(huì)啟動(dòng)進(jìn)氣切斷裝置 (如果裝備)。

       在確定和糾正迫使出現(xiàn)緊急停機(jī)的問(wèn)題之前，不要起動(dòng)發(fā)動(dòng)機(jī)。

       在發(fā)動(dòng)機(jī)再次起動(dòng)之前，緊急停機(jī)按鈕和進(jìn)氣切斷裝置都必須復(fù)位。

順時(shí)針旋轉(zhuǎn)緊急停機(jī)按鈕使按鈕復(fù)位，緊急停機(jī)按鈕會(huì)回到“突出”位置。

轉(zhuǎn)動(dòng)進(jìn)氣切斷裝置的復(fù)位旋鈕到 “開(kāi)”（OPEN）位置。

       確保發(fā)動(dòng)機(jī)兩側(cè)的進(jìn)氣切斷裝置都已復(fù)位。如果只復(fù)位了發(fā)動(dòng)機(jī)一側(cè)的進(jìn)氣切斷裝置，則會(huì)導(dǎo)致發(fā)動(dòng)機(jī)的損壞。
