柴油發(fā)電機(jī)是柴油發(fā)動(dòng)機(jī)與發(fā)電機(jī)（通常是交流發(fā)電機(jī)）的組合以產(chǎn)生電能。 柴油壓燃式發(fā)動(dòng)機(jī)通常設(shè)計(jì)成在燃油上運(yùn)行，但是有一些類型適用于其他液體燃料或天然氣。發(fā)電機(jī)是將其他形式的能源轉(zhuǎn)換成電能的機(jī)械設(shè)備。

柴油發(fā)電機(jī)組溫度壓力保護(hù)系統(tǒng)常見(jiàn)故障及對(duì)策，有以下兩點(diǎn)：

1、溫度顯示波動(dòng)且幅度大，有時(shí)顯示-1或1該故障原因有：

  第一，連接插頭接觸不良，可以擰緊，當(dāng)插頭松脫時(shí)CMR424顯示-1； 

  第二，探頭特性變壞，可以更換探頭，特別當(dāng)熱電阻探頭短路時(shí)CMR424顯示1；

  第三，電子板需要重新調(diào)整。

2、溫度顯示電子板故障或設(shè)定好的溫度發(fā)生變化可以用標(biāo)準(zhǔn)電阻箱或毫伏發(fā)生器輸入一組標(biāo)準(zhǔn)溫度信號(hào)進(jìn)行檢驗(yàn)，也可以用恒溫箱輸入一組實(shí)際溫度進(jìn)行校驗(yàn)。確屬電子板故障的應(yīng)該更換。設(shè)定好的溫度發(fā)生微小變化（2%以內(nèi)）屬于正常情況，是溫度漂移的結(jié)果。

A diesel generator is a combination of a diesel engine and a generator (usually an AC generator) to generate electrical energy. Diesel compression ignition engines are typically designed to run on fuel, but there are some types that are suitable for other liquid fuels or natural gas. A generator is a mechanical device that converts other forms of energy into electrical energy.

There are two common faults and countermeasures for the temperature and pressure protection system of diesel generator sets:

1. The temperature display fluctuates greatly, sometimes showing -1 or 1. The cause of this fault is:

Firstly, the connection plug has poor contact and can be tightened. When the plug is loose, CMR424 displays -1;

Secondly, if the characteristics of the probe deteriorate, it can be replaced, especially when the thermistor probe is short circuited and CMR424 displays 1;

Thirdly, the electronic board needs to be readjusted.

2. Temperature display electronic board faults or changes in the set temperature can be verified by inputting a set of standard temperature signals into a standard resistance box or millivolt generator, or by inputting a set of actual temperatures into a constant temperature box for verification. If it is indeed an electronic board malfunction, it should be replaced. Minor changes (within 2%) in the set temperature are normal and the result of temperature drift.
