Due to the particularity of the use of diesel generator set (it is generated by the kinetic energy generated by the high-speed rotation of the engine, which is converted into electric energy through the excitation of the generator), the machinery will generate a certain amount of heat during movement. At this time, the heat needs to be dissipated through cooling. Therefore, the generator set is generally cooled by fan water tank, so as to ensure that all mechanical parts of the generator set can be within a certain temperature control range.

但是，发电机组在使用过程中，经常会产生水箱温度过高，导致柴油机缸体过高，达到一定的温度时会自动停机（这是因为发电机组上装有水高温自动保护功能），如果机组上没有带有自动保护功能，那么会随着发动机的温度越来越高，发动机的缸体的温度也越来越高，润滑油的润滑效果会越来越差，损伤发动机缸体，那么，这个发电机组的水箱温度高是由什么引起的呢，下面，锋发动力为您详细分析发电机组水温过高的原因：

However, during the use of the generator set, the temperature of the water tank is often too high, resulting in the high temperature of the diesel engine cylinder block. When it reaches a certain temperature, it will shut down automatically (this is because the generator set is equipped with the automatic protection function of water high temperature). If the generator set is not equipped with the automatic protection function, the temperature of the engine cylinder block will be higher and higher as the engine temperature is higher and higher, and the lubrication effect of the lubricating oil will be worse and worse, If the engine block is damaged, what causes the high temperature of the water tank of the generator set? Below, Fengfa power will analyze the reasons for the high water temperature of the generator set in detail:

一、是喷油时间过早或过迟属，影响燃烧过程，引起补燃期过长，使冷却水接触气缸壁的时间相对延长，造成水温过高，这个一般是根据柴油机的不同，它的喷油时间不同，正常的发动机都不会存在这样的问题，除非机器收过损伤。

1、 The reason is that the injection time is too early or too late, which affects the combustion process, causes the supplementary combustion period to be too long, relatively prolongs the time for the cooling water to contact the cylinder wall, and causes the water temperature to be too high. This is generally based on the brand of diesel engine and its injection time. Such a problem will not exist in normal engines unless the machine is damaged.

二、是喷油量过大，造成混合气过浓，缓燃期、补燃期相应延长，而使水温过高。这个可能是由于突然加负载，或者突然加大油门造成

2、 The reason is that the fuel injection quantity is too large, resulting in too rich mixture, correspondingly prolonging the slow combustion period and supplementary combustion period, resulting in too high water temperature. This may be caused by sudden loading or sudden increase of throttle

三、是喷油器喷油压力过高或过低，使燃油的喷射行程和雾化质量受到影响。喷油压力过高，喷在燃烧 室壁上的柴油形成液态，不利于雾化险为夷喷油压力低，雾化质量差。喷油器滴油使供油量大，引起水温过高，严重时使喷油器燃损。

3、 The fuel injection pressure of the fuel injector is too high or too low, which affects the injection stroke and atomization quality of the fuel. If the injection pressure is too high, the diesel injected on the combustion chamber wall forms a liquid, which is not conducive to atomization. The injection pressure is low and the atomization quality is poor. The fuel injector drips oil to make the fuel supply large, which causes the water temperature to be too high, and in serious cases, the fuel injector burns out.

四、是配气相位失准，使气缸在压缩终了时压缩压力降低；进气不充分，延长了缓燃期和补燃期，引起水温过高。进气系统堵塞也会使混合气体过浓，发动机冒黑烟，动力下降，水温过高。气门和气门座圈磨损，活塞和缸套磨损均使压缩力降低，引起燃烧不良也使水温过高，动力性能下降。

4、 It is the misalignment of valve phase, which reduces the compression pressure of the cylinder at the end of compression; Insufficient air intake prolongs the slow combustion period and supplementary combustion period, resulting in too high water temperature. The blockage of the intake system will also make the mixture too thick, the engine emits black smoke, the power drops and the water temperature is too high. The wear of valve and valve seat ring, piston and cylinder liner reduce the compression force, cause poor combustion, make the water temperature too high and reduce the power performance.

五、是散热器堵塞、水垢过多及风扇胶带松等均会造成水温过高。水泵压力低，流量小，使冷却液循环速度悭，从而造成水温过高。需要定期清洗水箱，更换冷却液

5、 It is that the radiator is blocked, too much scale and the fan tape is loose, which will cause the water temperature to be too high. The low pressure and small flow of the water pump make the coolant circulation speed low, resulting in high water temperature. The water tank needs to be cleaned regularly and the coolant needs to be replaced

六、是发动机内部零部件之间摩擦阻力大，润滑条件不好，排气管或消间器堵塞，发动机负荷过大等也会造成水温过高的现象。检查使用的润滑油的油品及质量。

6、 High friction resistance between internal parts of the engine, poor lubrication conditions, blocked exhaust pipe or eliminator, excessive engine load and so on will also cause the phenomenon of too high water temperature. Check the oil and quality of the lubricating oil used.
