      確保所有的管夾箍和接頭擰緊。

      察看空氣濾清器保養(yǎng)指示器。當(dāng)黃色膜片進    入紅色區(qū)域或紅色柱塞定在可見位置內(nèi)時，    應(yīng)保養(yǎng)空氣濾清器。

冷卻系統(tǒng)

檢查冷卻系統(tǒng)有無泄漏或接頭是否松動。

檢查冷卻系統(tǒng)軟管有無綻裂，及管夾箍是否松馳。

檢查水泵有無泄漏的跡象。

檢查風(fēng)扇驅(qū)動皮帶是否松馳及有無損壞。

檢查冷卻液液位。如有必要，添加冷卻液。

被驅(qū)動設(shè)備

進行被驅(qū)動設(shè)備所需的任何保養(yǎng)。

如果需要，檢查被驅(qū)動設(shè)備的潤滑油油位。

如果發(fā)動機與被驅(qū)動設(shè)備之間有離合器，確保離合器已脫開。

如果發(fā)動機驅(qū)動的發(fā)電機，確保發(fā)電機輸出端的主斷路器已斷開。

確保接地是牢靠的。

燃油系統(tǒng)

在發(fā)動機運轉(zhuǎn)前或運轉(zhuǎn)中，燃油回油管路中的所有閥門都必須是打開的，以防止高的燃油壓力。

檢查燃油管路的接頭是否松動和有無泄漏。

確保向發(fā)動機供給燃油。

如果已有幾個星期沒有起動發(fā)動機，燃油可能已從燃油系統(tǒng)中泄出，所以在起動前首先用手動注油泵給發(fā)動機注油。

潤滑系統(tǒng)

檢查發(fā)動機曲軸箱機油油位，保持機油油位在機油油尺“發(fā)動機停車”側(cè)上的“加”和“滿”的標(biāo)記之間 。

檢查下列零部件處有無泄漏：曲軸密封、曲軸箱、機油濾清器、機油油道堵頭、傳感器和氣門室蓋。

將停機裝置和報警器復(fù)位。

自動起動

       要實現(xiàn)自動起動，發(fā)動機控制開關(guān)必須在“自動 ” 位置。當(dāng)遠程的起動/停車觸點閉合時，發(fā)動機自動地起動。

  警告：當(dāng)發(fā)動機處于“自動 ” 模式時，發(fā)動機可能在任何時刻起動。為避免人身傷害，當(dāng)發(fā)動機處于“自動 ” 模式時，人員必須遠離發(fā)動機。

手動起動

       警告： 如果有“不準(zhǔn)操作”（DO NOT OPERATE）的警告標(biāo)簽或類似標(biāo)簽掛在起動開關(guān)或操縱機構(gòu)上時，不要起動發(fā)動機或扳動任何操縱機構(gòu)。

       1.    執(zhí)行“發(fā)動機起動前”部分所敘述的步驟。

       2.    如果發(fā)動機與被驅(qū)動設(shè)備之間有離合器，確保       離合器已脫開。

       3.    將發(fā)動機控制開關(guān)轉(zhuǎn)到“手動起動”　　　　       （MAN.START）位置，手動起動發(fā)動機。

空氣起動馬達

把壓縮空氣壓力調(diào)到最大。

       注意：壓縮空氣壓力最大不能超過 1030 kPa (150 psi)

額外的壓縮空氣量。

電起動馬達

維持蓄電池中正確的電解液液位。

保持蓄電池中充滿電。

加熱蓄電池室或把蓄電池存放在較溫暖的地方。

用跨接電纜起動發(fā)動機,斯堪尼亞發(fā)電機組,斯堪尼亞發(fā)電機組維修,斯堪尼亞柴油發(fā)電機組維修,寧波斯堪尼亞柴油發(fā)電機組維修,浙江斯堪尼亞柴油發(fā)電機組維修,斯堪尼亞柴油發(fā)電機組維修保養(yǎng),斯堪尼亞柴油發(fā)電機組維修報價,當(dāng)使用外部電源起動發(fā)動機時，只能使用電壓與起動馬達的額定電壓相同的電源。

使用更高的電源電壓或電焊機的輸出電壓會損壞發(fā)動機的電氣系統(tǒng)。 電源沖擊會導(dǎo)致發(fā)動機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起動發(fā)動機 。

發(fā)動機起動后

暖機

       1.　在提高發(fā)動機轉(zhuǎn)速到額定轉(zhuǎn)速前， 讓發(fā)動機在      低怠速下運轉(zhuǎn)2到3分鐘，以使缸套水溫開始上升。

       2. 　在暖機期間，檢查所有儀表上的讀數(shù)。

       3. 　再一次圍繞發(fā)動機進行檢查 ，檢查發(fā)動機有無液體和空氣泄漏。

       注意：當(dāng)發(fā)動機在額定轉(zhuǎn)速和小負荷下運轉(zhuǎn)時，將較快地達到正常工作溫度。

接合被驅(qū)動設(shè)備

1. 確保各種儀表都處于相應(yīng)發(fā)動機轉(zhuǎn)速的正常范圍內(nèi)。

2. 增加發(fā)動機轉(zhuǎn)速到額定轉(zhuǎn)速。在加負荷以前，必須將發(fā)動機轉(zhuǎn)速增加到額定轉(zhuǎn)速。

3.    接合離合器以給發(fā)動機加負荷。

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

儀表

當(dāng)發(fā)動機在運轉(zhuǎn)時，要頻繁地觀察儀表。

定期地將儀表上的數(shù)據(jù)記錄下來 。

將記錄下來的數(shù)據(jù)與標(biāo)準(zhǔn)數(shù)據(jù)相比較，以確保發(fā)動機在正常運轉(zhuǎn)。 比較這些數(shù)據(jù)有助于知道發(fā)動機性能的變化。

確定并糾正儀表上任何明顯的讀數(shù)變化。

部分負荷運轉(zhuǎn)

延長在低怠速或較少負荷下的運轉(zhuǎn)時間會引起機油消耗量的增加和氣缸中積炭。

積炭會造成功率損失和性能變壞。

如有可能，至少每小時加滿負荷運轉(zhuǎn)一次，這樣能燒掉氣缸中過多的積炭。

警報器和停機裝置

為防止發(fā)動機損壞，警報器和停機裝置都設(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，警報器報警，以警告操作者。

當(dāng)出現(xiàn)更危急的不正常工作狀況時，停機裝置起作用，停止發(fā)動機的運轉(zhuǎn)。

停機裝置有助于防止設(shè)備的損壞。

       如果一種發(fā)動機保護裝置使發(fā)動機停機，則必須確定停機的原因。在再次起動發(fā)動機之前，進行必要的修理。

       應(yīng)熟悉下列項目：

警報器和停機裝置的類型

警報器和停機裝置的位置

使各種保護裝置起作用的各種工作狀態(tài)

起動發(fā)動機之前所需的復(fù)位步驟

手動停機

在發(fā)動機停機前，應(yīng)使其逐漸冷卻。

發(fā)動機已在負荷下運轉(zhuǎn)后，立即使發(fā)動機停機會造成過熱和發(fā)動機零部件的加速磨損。

渦輪增壓器中心殼體中的過高溫度會造成機油焦化問題。

使用以下的步驟作為發(fā)動機的一般停機程序：

1.  脫開發(fā)動機與被驅(qū)動設(shè)備之間的離合器

2.  在使發(fā)動機停機前，讓發(fā)動機有一段時間冷卻：

a. 如果啟用了發(fā)動機的冷機功能，則把發(fā)動機控制開關(guān)轉(zhuǎn)到“冷機/停機”（COOLDOWN/STOP） 位置。

b.如果沒有啟用發(fā)動機的冷機功能， 則讓發(fā)動機運轉(zhuǎn)在高怠速大約五分鐘，然后再讓發(fā)動機停機。

3.  把發(fā)動機控制開關(guān)轉(zhuǎn)到“關(guān)機/復(fù)位” （OFF/RESET）位置。

自動停機

當(dāng)發(fā)動機運轉(zhuǎn)在自動模式而遠程起動/停機觸點斷開時，將出現(xiàn)自動停機。

如果發(fā)動機啟用冷機功能，那么發(fā)動機在停機前將按設(shè)定的時間冷機，然后停機。否則，發(fā)動機會立即停機。

緊急停機

       緊急停機裝置僅用于 緊急情況。 正常停機不要使用緊急停機裝置。

發(fā)動機正常運轉(zhuǎn)時，緊急停機按鈕在“突起”位置。

當(dāng)需要緊急停機時，按下緊急停機按鈕。這會切斷發(fā)動機的燃油供應(yīng)。 這同時也會啟動進氣切斷裝置 (如果裝備)。

       在確定和糾正迫使出現(xiàn)緊急停機的問題之前，不要起動發(fā)動機。

       在發(fā)動機再次起動之前，緊急停機按鈕和進氣切斷裝置都必須復(fù)位。

順時針旋轉(zhuǎn)緊急停機按鈕使按鈕復(fù)位，緊急停機按鈕會回到“突出”位置。

轉(zhuǎn)動進氣切斷裝置的復(fù)位旋鈕到 “開”（OPEN）位置。

       確保發(fā)動機兩側(cè)的進氣切斷裝置都已復(fù)位。如果只復(fù)位了發(fā)動機一側(cè)的進氣切斷裝置，則會導(dǎo)致發(fā)動機的損壞。

Diesel generator set concept and its testing methods

Diesel generator set

Diesel generator set of power station of AC power supply device of a type, is a small independent power generation equipment, driven by an internal combustion engine, driving synchronous AC generator and power generation.

Modern diesel generating set comprises a diesel engine, a three-phase AC brushless synchronous generator, a control box ( screen ), the cooling water tank, coupling, fuel tank, muffler and the common base and other components of the overall steel. Diesel engine flywheel shell and the generator front end cover of the axial convex shoulder is positioned directly connected together, and a cylindrical elastic coupling from the flywheel direct drive generators to rotate, the way of connection are fixed together by bolts, so that the two are connected into a steel body, ensure diesel engine crankshaft and the concentricity of generator rotor in the specified range.

Diesel generator set is composed of internal combustion engine and synchronous generator which is formed by the combination of an internal combustion engine, maximum power by components of the mechanical load and thermal load limit, called the rated power, AC synchronous generator rated power refers to the rated speed, long continuous operation, the rated output power, usually diesel engine rated power output with synchronous alternator output rated power, called the matching ratio.

Diesel generator

1 Overview

Diesel generator is a small power generation equipment, means the diesel fuel, diesel engine prime mover driven generator power machinery. Diesel generator diesel engine, generator, by the general control box, fuel tank, starting and control storage battery, protection device, emergency cabinet and other components. Integral can be fixed on the foundation, location, can be installed in the trailer, for mobile use.

Diesel generator is a continuous operation of power generation equipment, if the continuous running at more than 12h, the output power will be lower than the rated power of about 90%.

Although the diesel generator power is low, but because of its small size, flexible, lightweight, supporting complete, convenient operation and maintenance, and is widely used in mining, railway, field construction sites, road traffic safeguard, and factory, enterprise, hospital departments, as a backup power source or a temporary power supply. A newly developed in recent years, the unmanned automatic emergency power station, a more expanded the range of use of the generating unit.

At present, China's export production capacity of the production plant has more than 10Tianjin power equipment factory. Products are exported to Europe and the dozens of countries and regions, well received.

2classification and specifications

Diesel generator to generator power output size classification, unit energy from 10kW-750kW various specifications. Each kind of specification and consists of protecting type ( with super speed, high water temperature, low oil pressure protection device ), emergency and mobile power station type structures. The mobile station is divided again for speed and vehicle speed to match the high-speed off-road type and low speed normal mobile type.

3order matters needing attention

Diesel generating sets export inspection according to the provisions of the contract or agreement about the technical or economic indicators for inspection, users in the selection and contract, should pay attention to the following points:
