檢查蓄電池電纜的連接是否良好和有無(wú)腐蝕。

檢查儀表和控制面板狀態(tài)是否良好。

將停機裝置和報警器復位。

自動(dòng)起動(dòng)

       要實(shí)現自動(dòng)起動(dòng)，發(fā)動(dòng)機控制開(kāi)關(guān)必須在“自動(dòng) ” 位置。當遠程的起動(dòng)/停車(chē)觸點(diǎn)閉合時(shí)，發(fā)動(dòng)機自動(dòng)地起動(dòng)。

  警告：當發(fā)動(dòng)機處于“自動(dòng) ” 模式時(shí)，發(fā)動(dòng)機可能在任何時(shí)刻起動(dòng)。為避免人身傷害，當發(fā)動(dòng)機處于“自動(dòng) ” 模式時(shí)，人員必須遠離發(fā)動(dòng)機。

手動(dòng)起動(dòng)

       警告： 如果有“不準操作”（DO NOT OPERATE）的警告標簽或類(lèi)似標簽掛在起動(dòng)開(kāi)關(guān)或操縱機構上時(shí)，不要起動(dòng)發(fā)動(dòng)機或扳動(dòng)任何操縱機構。

       1.    執行“發(fā)動(dòng)機起動(dòng)前”部分所敘述的步驟。

       2.    如果發(fā)動(dòng)機與被驅動(dòng)設備之間有離合器，確保       離合器已脫開(kāi)。

       3.    將發(fā)動(dòng)機控制開(kāi)關(guān)轉到“手動(dòng)起動(dòng)”　　　　       （MAN.START）位置，手動(dòng)起動(dòng)發(fā)動(dòng)機。

空氣起動(dòng)馬達

把壓縮空氣壓力調到最大。

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

額外的壓縮空氣量。

電起動(dòng)馬達

維持蓄電池中正確的電解液液位。

保持蓄電池中充滿(mǎn)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(dòng)發(fā)動(dòng)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,斯堪尼亞柴油發(fā)電機組維修報價(jià),當使用外部電源起動(dòng)發(fā)動(dòng)機時(shí)，只能使用電壓與起動(dòng)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(huì )損壞發(fā)動(dòng)機的電氣系統。 電源沖擊會(huì )導致發(fā)動(dòng)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(lái)起動(dòng)發(fā)動(dòng)機 。

發(fā)動(dòng)機起動(dòng)后

暖機

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

       2. 　在暖機期間，檢查所有儀表上的讀數。

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

       注意：當發(fā)動(dòng)機在額定轉速和小負荷下運轉時(shí)，將較快地達到正常工作溫度。

接合被驅動(dòng)設備

1. 確保各種儀表都處于相應發(fā)動(dòng)機轉速的正常范圍內。

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

3.    接合離合器以給發(fā)動(dòng)機加負荷。

4. 繼續檢查所有儀表的讀數和被驅動(dòng)設備。

儀表

當發(fā)動(dòng)機在運轉時(shí)，要頻繁地觀(guān)察儀表。

定期地將儀表上的數據記錄下來(lái) 。

將記錄下來(lái)的數據與標準數據相比較，以確保發(fā)動(dòng)機在正常運轉。 比較這些數據有助于知道發(fā)動(dòng)機性能的變化。

確定并糾正儀表上任何明顯的讀數變化。

部分負荷運轉

延長(cháng)在低怠速或較少負荷下的運轉時(shí)間會(huì )引起機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(mǎn)負荷運轉一次，這樣能燒掉氣缸中過(guò)多的積炭。

警報器和停機裝置

為防止發(fā)動(dòng)機損壞，警報器和停機裝置都設定在臨界工作溫度、壓力或轉速下。

當出現不正常的工作狀況時(shí)，警報器報警，以警告操作者。

當出現更危急的不正常工作狀況時(shí)，停機裝置起作用，停止發(fā)動(dòng)機的運轉。

停機裝置有助于防止設備的損壞。

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

       應熟悉下列項目：

警報器和停機裝置的類(lèi)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(dòng)發(fā)動(dòng)機之前所需的復位步驟

手動(dòng)停機

在發(fā)動(dòng)機停機前，應使其逐漸冷卻。

發(fā)動(dòng)機已在負荷下運轉后，立即使發(fā)動(dòng)機停機會(huì )造成過(guò)熱和發(fā)動(dòng)機零部件的加速磨損。

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

使用以下的步驟作為發(fā)動(dòng)機的一般停機程序：

1.  脫開(kāi)發(fā)動(dòng)機與被驅動(dòng)設備之間的離合器

2.  在使發(fā)動(dòng)機停機前，讓發(fā)動(dòng)機有一段時(shí)間冷卻：

a. 如果啟用了發(fā)動(dòng)機的冷機功能，則把發(fā)動(dòng)機控制開(kāi)關(guān)轉到“冷機/停機”（COOLDOWN/STOP） 位置。

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

3.  把發(fā)動(dòng)機控制開(kāi)關(guān)轉到“關(guān)機/復位” （OFF/RESET）位置。

自動(dòng)停機

當發(fā)動(dòng)機運轉在自動(dòng)模式而遠程起動(dòng)/停機觸點(diǎn)斷開(kāi)時(shí)，將出現自動(dòng)停機。

如果發(fā)動(dòng)機啟用冷機功能，那么發(fā)動(dòng)機在停機前將按設定的時(shí)間冷機，然后停機。否則，發(fā)動(dòng)機會(huì )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(dòng)機正常運轉時(shí)，緊急停機按鈕在“突起”位置。

當需要緊急停機時(shí)，按下緊急停機按鈕。這會(huì )切斷發(fā)動(dòng)機的燃油供應。 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緊急停機的問(wèn)題之前，不要起動(dòng)發(fā)動(dòng)機。

       在發(fā)動(dòng)機再次起動(dòng)之前，緊急停機按鈕和進(jìn)氣切斷裝置都必須復位。

順時(shí)針旋轉緊急停機按鈕使按鈕復位，緊急停機按鈕會(huì )回到“突出”位置。

轉動(dòng)進(jìn)氣切斷裝置的復位旋鈕到 “開(kāi)”（OPEN）位置。

       確保發(fā)動(dòng)機兩側的進(jìn)氣切斷裝置都已復位。如果只復位了發(fā)動(dòng)機一側的進(jìn)氣切斷裝置，則會(huì )導致發(fā)動(dòng)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:

(1) if environmental conditions and diesel generator calibration value between environmental conditions, should be in when signing the temperature, humidity and altitude value, to provide suitable models and ancillary equipment;

(2) to illustrate the use of the cooling means, especially the large capacity units, more attention should be paid;

(3) the order, except should describe the unit models, also shows what type;

(4) diesel generator voltage regulation rate were 1%,2%,2.5% of the rated voltage. What, should note;

(5) the normal supply, to provide a certain amount of wearing parts, otherwise need, also should note.

4 test items and methods
