夏季預防柴油發電機組溫度過高我有方法!

01/正確使用封閉式冷卻系

01/ proper use of closed cooling system

現代柴油發動機大部分都采用封閉式冷卻系,散熱器蓋是密封的,并增添了一個膨脹水箱。發動機工作時,冷卻液蒸氣進入膨脹水箱內,冷卻后又流回散熱器,可防止冷卻液大量蒸發損失,并可提高冷卻液的沸點溫度。該冷卻系應使用具有防腐蝕、防沸、防凍和防水垢的優質冷卻液,并且在使用中必須保證密封,才能收到效果。

D88尊龙Most of modern diesel engines use closed cooling system, the radiator cover is sealed, and an expansion tank is added. When the engine works, the coolant vapor enters the expansion tank and flows back to the radiator, which can prevent a large amount of evaporation loss of the coolant and increase the boiling point temperature of the coolant. The cooling system should use high quality coolant which is corrosion resistant, anti boiling, antifreezing and waterproofing, and must be sealed in use before receiving the effect.

D88尊龙02/保持冷卻系外部和內部清潔

02/ maintains the external and internal cleanliness of the cooling system

這一點是提高散熱效能的重要條件之一。散熱器外部沾有泥土、油污或散熱片因碰撞變形時,均會影響風的通過,散熱器散熱效果變差,造成冷卻液溫度過高。因此發現發電機組散熱器出現這種情況應及時清洗或者修整。另外,發電機組冷卻水箱內積有水垢、泥砂或油污時,都會影響冷卻液的傳熱。加注劣質冷卻液或水,將會造成冷卻系積垢增多,而水垢的傳熱能力只有金屬的幾十分之一,從而冷卻效果變差。所以冷卻系統中應加注優質的冷卻液。

D88尊龙This is one of the important conditions to improve the heat dissipation efficiency. The exterior of the radiator is contaminated by soil, oil or heat sink, which will affect the passing of the wind, and the heat dissipation effect of the radiator becomes worse and the coolant temperature is too high. Therefore, it is found that the generator radiator should be cleaned or repaired in time. In addition, when the cooling water tank of the generator set contains scale, mud or oil, it will affect the heat transfer of the coolant. Adding poor quality coolant or water will cause more fouling in the cooling system, and the heat transfer capacity of the scale is only a fraction of that of the metal, resulting in a worse cooling effect. Therefore, high quality coolant should be added to the cooling system.

03/保持冷卻液量充足

03/ maintains sufficient coolant volume

當發動機處于冷態時,冷卻液液面應該位于膨脹水箱的高和低標志之間口如果液面低于膨脹水箱的低標志時,應及時添加。注意,膨脹水箱內的冷卻液不能注滿,應該留有膨脹余地。

When the engine is in cold state, the liquid level of the coolant should be located between the highest and the lowest mark of the expansion tank. If the liquid level is lower than the lowest mark of the expansion tank, it should be added in time. Note that the coolant in the expansion tank can not be filled, and there should be room for expansion.

D88尊龙04/保持風扇膠帶張緊力適度

D88尊龙04/ keeping the fan belt tensioning force moderate

風扇膠帶過松,使水泵轉速過低,影響冷卻液的循環,并會加速膠帶的磨損。但膠帶過緊,又會使水泵軸承磨損。另外,膠帶上不能沾有油污。因此,應定期檢查調整風扇膠帶的張緊力。

D88尊龙The fan tape is too loose, which makes the pump speed too low, affects the circulation of coolant, and accelerates the abrasion of the adhesive tape. But the tape is too tight, it will also make the pump bearing wear. In addition, the tape can not be contaminated with oil. Therefore, regular inspection should be made to adjust the tension force of the fan belt.

05/避免柴油發電機組大負荷工作

D88尊龙05/ avoids large load work of diesel generator set

當發動機處于冷態時,冷卻液液面應該位于膨脹水箱的高和低標志之間口如果液面低于膨脹水箱的低標志時,應及時添加。注意,膨脹水箱內的冷卻液不能注滿,應該留有膨脹余地。

D88尊龙When the engine is in cold state, the liquid level of the coolant should be located between the highest and the lowest mark of the expansion tank. If the liquid level is lower than the lowest mark of the expansion tank, it should be added in time. Note that the coolant in the expansion tank can not be filled, and there should be room for expansion.

D88尊龙06/注意機房的通風良好

06/ pay attention to the good ventilation of the machine room

特別是水箱的排風排煙要良好,地面整潔,不要出現油污,灰塵等。

D88尊龙In particular, the exhaust and smoke of the water tank should be good, and the floor should be clean.
