水介質(zhì)能否替代發(fā)動(dòng)機(jī)冷卻液？這是廣大瓦斯發(fā)生器用戶相對(duì)忽視的問(wèn)題，小編說(shuō)明了瓦斯發(fā)動(dòng)機(jī)組冷卻劑的重要作用。

Can water replace engine coolant? This is a problem relatively ignored by the majority of gas generator users. The editor explained the important role of gas engine coolant.

瓦斯發(fā)動(dòng)機(jī)正常工作溫度為65-70°，比普通的發(fā)動(dòng)機(jī)要低15-20°，過(guò)高的發(fā)動(dòng)機(jī)溫度會(huì)使混合氣體爆燃，影響發(fā)動(dòng)機(jī)正常運(yùn)轉(zhuǎn)同時(shí)會(huì)加速發(fā)動(dòng)機(jī)油蛻變，使之產(chǎn)生積碳，容易形成油膜決裂，光滑不良，磨損加劇。因而，運(yùn)用發(fā)動(dòng)機(jī)冷卻液對(duì)瓦斯發(fā)動(dòng)機(jī)停止恰當(dāng)降溫尤為重要，能夠保證發(fā)動(dòng)機(jī)正常工作。

The normal working temperature of gas engine is 65-70 °, which is 15-20 ° lower than that of ordinary engine. Too high engine temperature will deflagrate the mixed gas, affect the normal operation of the engine, and accelerate the degeneration of engine oil, causing carbon deposition, easy to form oil film cracking, poor smoothness, and intensified wear. Therefore, it is particularly important to use engine coolant to properly cool the gas engine, which can ensure the normal operation of the engine.

但假如發(fā)動(dòng)機(jī)的溫度太低，冷卻過(guò)度，也會(huì)產(chǎn)生反作用，使發(fā)動(dòng)機(jī)蓋的熱量損失加大，不利于可燃混合氣體的構(gòu)成和熄滅，并招致發(fā)動(dòng)機(jī)油粘度變大，摩擦損失增加，形成發(fā)動(dòng)機(jī)有效功率降低。

However, if the temperature of the engine is too low and the cooling is too excessive, it will also have a reaction, which will increase the heat loss of the engine cover, which is not conducive to the composition and extinction of the combustible gas mixture, and cause the viscosity of the engine oil to increase, the friction loss to increase, resulting in the reduction of the effective power of the engine.

在實(shí)踐運(yùn)用過(guò)程中，普通應(yīng)用冷卻液的小循環(huán)和大循環(huán)處理瓦斯發(fā)動(dòng)機(jī)的冷卻光滑問(wèn)題，使發(fā)動(dòng)機(jī)得到適度的冷卻，從而使其堅(jiān)持在適合的溫度范圍內(nèi)工作。通常關(guān)于瓦斯發(fā)動(dòng)機(jī)的水冷卻系統(tǒng)，當(dāng)缸蓋冷卻水套中的冷卻液溫度到達(dá)60°左右時(shí)，大循環(huán)啟動(dòng)，可確保瓦斯發(fā)動(dòng)機(jī)正常工作。

In the process of practical application, small circulation and large circulation of coolant are commonly used to deal with the problem of smooth cooling of gas engine, so that the engine can be moderately cooled, so that it can work within a suitable temperature range. Generally, for the water cooling system of gas engine, when the coolant temperature in the cylinder head cooling water jacket reaches about 60 °, the large cycle starts, which can ensure the normal operation of gas engine.

在實(shí)踐運(yùn)用中用戶常常疏忽發(fā)動(dòng)機(jī)冷卻液的運(yùn)用，而簡(jiǎn)單的用水作為發(fā)電機(jī)組的冷卻介質(zhì)。隨著發(fā)電機(jī)組的運(yùn)轉(zhuǎn)冷卻水損耗嚴(yán)重，需求頻繁補(bǔ)加水分，且運(yùn)用一段時(shí)間后就會(huì)結(jié)垢，招致發(fā)電機(jī)組冷卻效果降落，發(fā)動(dòng)機(jī)運(yùn)轉(zhuǎn)溫度升高，影響發(fā)電機(jī)組的正常發(fā)電。

In practice, users often neglect the use of engine coolant, and simply use water as the cooling medium of the generator set. With the serious loss of cooling water in the operation of the generator set, it is necessary to add water frequently, and it will scale after using for a period of time, causing the cooling effect of the generator set to decline, and the operating temperature of the engine to rise, affecting the normal power generation of the generator set.
