In the whole body of diesel generator set, radiator plays an important role in ensuring the normal operation of the unit. The maintenance cycle of the radiator of the diesel generator set is once every 200 hours of operation.

柴油發(fā)電機組散熱器的外部清潔：用加入適量清潔劑的熱水噴洗，要注意把蒸氣或水從散熱器前面向風(fēng)扇噴射。噴洗時，要用布將柴油機及交流發(fā)電機遮擋起來。遇到散熱器有大量頑固的沉積物時，則應(yīng)把散熱器拆下浸在熱的堿水中約20分鐘，然后用熱水清洗。

External cleaning of the radiator of the diesel generator set: spray with hot water with appropriate amount of detergent. Pay attention to spraying steam or water from the front of the radiator to the fan. During spraying and washing, the diesel engine and alternator shall be covered with cloth. If the radiator has a large amount of stubborn deposits, it should be removed and immersed in hot alkaline water for about 20 minutes, and then cleaned with hot water.

柴油發(fā)電機組散熱器的內(nèi)部清潔：把散熱器中水排干，然后把散熱器與管子相連的地方拆開并封口；向散熱器倒入45度的4%的酸溶液，約15分鐘后排干酸溶液，檢查散熱器；如果仍有水垢，則用8%的酸溶液再洗一次；除垢后用3%的堿溶液中和兩次，再用清水沖洗三次以上；

Internal cleaning of radiator of diesel generator set: drain the water in radiator, then disassemble and seal the connection between radiator and pipe; Pour 4% acid solution at 45 ° C into the radiator, drain the acid solution for about 15 minutes, and check the radiator; If there is still scale, wash again with 8% acid solution; After descaling, neutralize it twice with 3% alkali solution, and then rinse it with clean water for more than three times;

所有工作完成后，檢查散熱器是否漏水，如果漏水要及時修補，如果不漏水則重新裝回，散熱器裝回后應(yīng)重新灌滿清水并加入防銹劑。

After all work is completed, check whether the radiator leaks. If it leaks, repair it in time. If it does not, reinstall it. After the radiator is installed, fill it with clean water and add rust inhibitor.

柴油發(fā)電機組屬自備電站（交流供電設(shè)備)的一種類型，是一種小型獨立的發(fā)電設(shè)備，以內(nèi)燃發(fā)動機作動力，驅(qū)動同步交流發(fā)電機而發(fā)電。

Diesel generator set is a type of self-contained power station (AC power supply equipment), which is a small independent power generation equipment. It uses internal combustion engine as power to drive synchronous alternator to generate electricity.

柴油發(fā)電機組由柴油機、交流無刷同步發(fā)電機、控制箱（屏）、散熱水箱、聯(lián)軸器、燃油箱、消聲器及公共底座等組成鋼性整體。柴油機的飛輪殼與發(fā)電機前段蓋的軸向采用凸肩定位直接連接構(gòu)成一體，并采用聯(lián)軸器由飛輪直接驅(qū)動發(fā)電機的旋轉(zhuǎn)，其連接方式由高強固定在一起，使兩者連接成一鋼體，保證了柴油機的曲軸與發(fā)電機轉(zhuǎn)子的同心度在規(guī)定的范圍內(nèi)。

The diesel generator set consists of a diesel engine, an AC brushless synchronous generator, a control box (panel), a radiator tank, a coupling, a fuel tank, a muffler and a common base. The axial direction of the flywheel housing of the diesel engine and the front cover of the generator is directly connected by shoulder positioning to form a whole, and the flywheel directly drives the rotation of the generator by coupling. The connection mode is fixed together by high strength, so that the two are connected into a steel body, which ensures that the concentricity of the crankshaft of the diesel engine and the rotor of the generator is within the specified range.

一、潤滑

1、 Lubrication

選用合適的潤滑劑和潤滑方法，用理想的流體摩擦取代干摩擦，這是減少摩擦和磨損的方法。對于發(fā)電機組而言，要按照不同發(fā)動機的具體要求，根據(jù)季節(jié)和使用地域的不同選擇合適牌號的潤滑油。

It is a way to reduce friction and wear by selecting appropriate lubricants and lubrication methods and replacing dry friction with ideal fluid friction. For the generator set, according to the specific requirements of different engines, according to the different seasons and regions of use, select the appropriate brand of lubricating oil.

二、正確選擇材料

2、 Select materials correctly

按照基本磨損的形式，正確選擇材料是提高機械設(shè)備零部件耐磨性的關(guān)鍵因素之一。在設(shè)計制造時應(yīng)選用疲勞強度高、防腐性能好、耐磨耐高溫的材料。同時要注意配對材料的互溶性，使其有合適的組合。

According to the form of basic wear, the correct selection of materials is one of the key factors to improve the wear resistance of mechanical equipment parts. Materials with high fatigue strength, good corrosion resistance, wear resistance and high temperature resistance shall be selected during design and manufacturing. At the same time, attention should be paid to the mutual solubility of the mating materials to make them have a proper combination.

三、進(jìn)行表面處理

3、 Surface treatment

通過使用各種表面處理方法，如表面熱處理（鋼的表面淬火等）、表面化學(xué)熱處理（鋼的表面滲碳、滲氮等）、噴涂、噴焊、鍍層、沉積、滾壓等，改善表面的耐磨性。這是更和更經(jīng)濟(jì)的方法之一。

Various surface treatment methods, such as surface heat treatment (steel surface quenching, etc.), surface chemical heat treatment (steel surface carburizing, nitriding, etc.), spraying, spray welding, plating, deposition, rolling, etc., are used to improve the wear resistance of the surface. This is one of the more and more economical ways.

四、合理的結(jié)構(gòu)設(shè)計

4、 Reasonable structural design

正確合理的結(jié)構(gòu)設(shè)計是減少發(fā)電機組零件磨損和提高其耐磨性的途徑。結(jié)構(gòu)要有利于摩擦副間表面保護(hù)膜的形成和恢復(fù)、壓力的均勻分布、摩擦熱的散逸、磨屑的排出以及防止外界磨料、灰塵的進(jìn)入等。在結(jié)構(gòu)設(shè)計中，可以應(yīng)用置換原理，即允許系統(tǒng)中一個零件磨損以保護(hù)另一個重要的零件；也可以使用轉(zhuǎn)移原理，即允許摩擦副中另一零件快速磨損而保護(hù)貴重的零件。

Correct and reasonable structure design is the way to reduce the wear of generator set parts and improve their wear resistance. The structure shall be conducive to the formation and recovery of surface protective film between friction pairs, the uniform distribution of pressure, the dissipation of friction heat, the discharge of wear debris and the prevention of the entry of external abrasives and dust. In the structural design, the replacement principle can be applied, that is, one part of the system is allowed to wear to protect another important part; The transfer principle can also be used, which allows another part in the friction pair to wear rapidly and protect valuable parts.

五、工作條件

5、 Working conditions

盡量避免過大的負(fù)荷、過高的運動速度和工作溫度，創(chuàng)造良好的環(huán)境條件。

Try to avoid excessive load, excessive movement speed and working temperature, and create good environmental conditions.
