Due to the particularity of gas 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 machine will generate certain heat when it is in motion. At this time, the heat needs to be sent out through cooling, so the generator set is generally cooled through the fan water tank, so as to ensure all mechanical zero of the generator set All parts can be controlled within a certain temperature range.

但是，发电机组在使用过程中，经常会产生水箱温度过高，导致瓦斯发电机组缸体过高，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, which leads to the high temperature of the cylinder block of the gas generator set. When it reaches a certain temperature, it will stop automatically (this is because the generator set is equipped with the automatic protection function of water high temperature). If the generator set does not have the automatic protection function, the temperature of the cylinder block of the engine will increase with the increasing temperature of the engine The lubricating effect of the lubricating oil will be worse and worse, and the engine block will be damaged. Then, what is the reason for the high temperature of the water tank of the generator set

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，这个一般是根据瓦斯发电机组的品牌不同，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、 If the injection time is too early or too late, it will affect the combustion process, cause the supplementary combustion period to be too long, make the cooling water contact the cylinder wall for a relatively long time, and cause the water temperature to be too high. Generally, according to the brand of gas generator set, the injection time is different, and the normal engine will not have such a problem, unless the machine has been 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 injection quantity is too large, the mixture is too rich, the slow combustion period and supplementary combustion period are prolonged correspondingly, and the water temperature is too high. This may be due to a sudden load, or a sudden increase in the 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 室壁上的瓦斯发电机组形成液态，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增大，引起水温过高，严重时使喷油器燃损。

3、 The reason is that the injection pressure of the 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 gas generator unit sprayed on the combustion chamber wall will form a liquid state, which is not conducive to the risk of atomization. The dropping oil of the fuel injector increases the fuel supply quantity, causes the water temperature to be too high, and causes the fuel injector to burn in serious cases.

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，排气彻底，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、 The reason is that the valve timing is out of alignment, so that the compression pressure of the cylinder is reduced at the end of compression; the intake air is not sufficient, and the exhaust gas is complete, which prolongs the slow combustion period and supplementary combustion period, and causes the water temperature to be too high. If the intake system is blocked, the mixture will be too rich, the engine will emit black smoke, the power will drop, and the water temperature will be too high. The wear of valve and valve seat ring, piston and cylinder liner can reduce the compression force, cause poor combustion, and make the water temperature too high and the power performance decline.

五、是散热器堵塞、水垢过多及风扇胶带松弛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 blocked radiator, too much scale and loose fan tape that can cause high water temperature. The low pressure and low flow of the water pump make the circulation speed of the coolant low, resulting in the high water temperature. The water tank needs to be cleaned regularly and the coolant needs to be changed

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、 It is the high friction resistance between the internal parts of the engine, bad lubrication conditions, exhaust pipe or eliminator blockage, engine load is too large and so on will also cause the phenomenon of high water temperature. Check the quality of the lubricating oil used.
