夏季预防柴油发电机组温度过高我有方法!

01/正确使用封闭式冷却系

01/ proper use of closed cooling system

现代柴油发动机大部分都采用封闭式冷却系,散热器盖是密封的,并增添了一个膨胀水箱。发动机工作时,冷却液蒸气进入膨胀水箱内,冷却后又流回散热器,可防止冷却液大量蒸发损失,并可提高冷却液的沸点温度。该冷却系应使用具有防腐蚀、防沸、防冻和防水垢的优质冷却液,并且在使用中必须保证密封,才能收到效果。

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.

02/保持冷却系外部和内部清洁

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

这一点是提高散热效能的重要条件之一。散热器外部沾有泥土、油污或散热片因碰撞变形时,均会影响风的通过,散热器散热效果变差,造成冷却液温度过高。因此发现发电机组散热器出现这种情况应及时清洗或者修整。另外,发电机组冷却水箱内积有水垢、泥砂或油污时,都会影响冷却液的传热。加注劣质冷却液或水,将会造成冷却系积垢增多,而水垢的传热能力只有金属的几十分之一,从而冷却效果变差。所以冷却系统中应加注优质的冷却液。

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/保持冷却液量充足

03/ maintains sufficient coolant volume

当发动机处于冷态时,冷却液液面应该位于膨胀水箱的最高和最低标志之间口如果液面低于膨胀水箱的最低标志时,应及时添加。注意,膨胀水箱内的冷却液不能注满,应该留有膨胀余地。

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.

04/保持风扇胶带张紧力适度

04/ keeping the fan belt tensioning force moderate

风扇胶带过松,使水泵转速过低,影响冷却液的循环,并会加速胶带的磨损。但胶带过紧,又会使水泵轴承磨损。另外,胶带上不能沾有油污。因此,应定期检查调整风扇胶带的张紧力。

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/避免柴油发电机组大负荷工作

05/ avoids large load work of diesel generator set

当发动机处于冷态时,冷却液液面应该位于膨胀水箱的最高和最低标志之间口如果液面低于膨胀水箱的最低标志时,应及时添加。注意,膨胀水箱内的冷却液不能注满,应该留有膨胀余地。

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.

06/注意机房的通风良好

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

特别是水箱的排风排烟要良好,地面整洁,不要出现油污,灰尘等。

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

关于瓦斯发电机组 就先介绍到这里了,相信大家在实际的工作中会用到相关知识,如果您有这方面的需要,欢迎前来选购。

on the gas generator set first introduced here, I believe that you will use the relevant knowledge in the actual work, if you have the needs of this area, welcome to buy.
