Can the water medium of the biogas generator replace the coolant of the engine? This is a problem ignored by the majority of users of the biogas generator. The important role of the engine coolant is explained to you by the Chen Long editor of the biogas generator.

　　一是沼氣發電機組發動機冷卻液的作用

　　One is the function of engine coolant of biogas generator set沼氣發動機正常工作溫度為65-70°。過高的發動機溫度會使混合氣體放氣，影響發動機的正常運轉，并加速發動機機油的變質，導致積炭，容易造成油膜破裂，潤滑不良，磨損加重。因此，使用發動機冷卻劑對沼氣發動機進行適當的冷卻，以保證發動機的正常運行尤為重要。
 

　　The normal operating temperature of biogas engine is 65-70 °. Too high engine temperature will deflate the mixed gas, affect the normal operation of the engine, accelerate the deterioration of engine oil, lead to carbon deposition, easy to cause oil film rupture, poor lubrication, and increased wear. Therefore, it is very important to use engine coolant to cool the biogas engine properly to ensure the normal operation of the engine.

　　但是,如果發動機的溫度太低,過度冷卻也會產生副作用,使發動機罩的熱損失增加,不利于形成和燃燒的可燃混合氣體,并導致機油粘度高,摩擦損失增加,導致減少了發動機的有效功率。

　　However, if the temperature of the engine is too low, excessive cooling will also have side effects, which will increase the heat loss of the engine hood, which is not conducive to the formation and combustion of combustible gas mixture, and lead to high oil viscosity, increased friction loss, resulting in the reduction of the effective power of the engine.

　　沼氣發電機組，發動機冷卻液

　　Biogas generator set, engine coolant

　　在實際使用中，一般采用發動機冷卻液循環的大小來解決沼氣發動機的冷卻和潤滑問題，使發動機得到適當的冷卻，使其保持在更合適的溫度范圍內。通常對于沼氣發電機組水冷卻系統，當氣缸蓋冷卻套內的冷卻劑溫度達到60°左右時，開始進行大循環，以保證沼氣發動機的正常運行。

　　In practical use, the size of engine coolant circulation is generally used to solve the cooling and lubrication problems of biogas engine, so that the engine can be properly cooled and kept in the most appropriate temperature range. Generally, for the water cooling system of biogas generator set, when the coolant temperature in the cooling sleeve of the cylinder head reaches about 60 °, a large cycle is started to ensure the normal operation of biogas engine.

　　2. 沼氣發電機組的水介質能否代替發動機的冷卻劑在實際應用中,用戶常常忽略發動機冷卻液的使用和簡單使用水作為冷卻介質的發電機組,發電機組的操作冷卻水流失嚴重,水經常需要添加,和規模將形成使用一段時間后,導致發電機組的冷卻效果降低,增加發動機工作溫度,影響發電機組的正常發電。

　　2. Can the water medium of biogas generator replace the engine coolant? In practical application, users often neglect the use of engine coolant and the generator set that simply uses water as the cooling medium. The operation cooling water of generator set is seriously lost, and the water often needs to be added, and the scale will form a period of use, which will reduce the cooling effect of generator set, Increase the working temperature of the engine and affect the normal generation of the generator set.

　　此外，油水散熱器也會因氧化而腐蝕，導致散熱器穿孔泄漏，進而導致發電機組故障。

　　In addition, the oil-water radiator will also be corroded due to oxidation, which will lead to radiator perforation and leakage, and then lead to generator failure.
