教您低温下如何正确启动燃气发电机组?

返回 2021.05.17 来源:http://www.huannengpower.com
当外界气温下降至-10°C以下时,燃气发电机组处在低温天气中,柴油机冷启动就有一定困难;当气温降至-40°C以下时,如果不采取一些低温启动措施,燃气机则根本无法启动,小编就简单整理几点低温启动燃气发电机组的具体方法:
When the outside temperature drops to - 10 ° When the temperature is below C, the diesel generator set is in low temperature weather, so it is difficult to start the diesel engine cold; When the temperature drops to - 40 ° C below, if you do not take some low-temperature start-up measures, the diesel engine will not start at all
(1)热水预温法
(1) Hot water pre heating method
此种方法适用于采用软 化热水作为冷 却液,且软 化热水比较方便的单位。具体做法是:先向冷却系加注40~50°的温水(以防猛加沸水使水散热器芯管、汽缸盖发生胀裂),然后连续加热水(让水流出缸体),逐渐提高水温进行预热。当流出的水温度较高时再关闭放水开关即可。
This method is suitable for the unit that uses softened hot water as coolant and softened hot water is more convenient. The specific method is as follows: fill 40 ~ 50 oil into the cooling system first ° Then continuously heat the water (let the water flow out of the cylinder block), and gradually increase the water temperature for preheating. When the temperature of the outflow water is high, turn off the drain switch.、

(2)蒸汽预热法
(2) Steam preheating method
即让蒸汽通过管道从水散热器的下水管进入冷 却系,或直接进入燃气发电机组冷 却水套,用蒸汽预热柴油机汽缸体。此种方法适用于采用软化水作为冷 却液的情况。
That is to say, let the steam enter the cooling system from the down pipe of the water radiator through the pipe, or directly enter the cooling water jacket of the gas generator set, and preheat the cylinder block of the diesel engine with steam. This method is suitable for the use of softened water as coolant.
(3)采用处置强制循环式燃油加热器
(3) Using forced circulation fuel heater
该方法是利用随机柴油,通过燃油加热器附带的水泵将柴油机冷  却系统内的冷 却液抽出,经过加热器辐射加热后再循环至柴油机汽缸内,此时汽缸、活塞、活塞环以及其它摩擦副的温度随之升高。这种方式能将柴油机汽缸体温度加热到40~50°C左右。柴油机的机油得到加热后黏度降低,柴油机的润滑条件得到改善。
In this method, the coolant in the cooling system of the diesel engine is pumped out by the pump attached to the fuel heater, and then recycled to the cylinder of the diesel engine after being radiated and heated by the heater. At this time, the temperature of the cylinder, piston, piston ring and other friction pairs increases. In this way, the temperature of diesel engine cylinder block can be heated to 40 ~ 50 ℃ ° About C. The viscosity of diesel engine oil decreases after heating, and the lubrication condition of diesel engine is improved.
(4)在进气管内安装螺旋式电阻加热器
(4) Installation of spiral resistance heater in intake pipe
这种装置由蓄电池供电,启动前接通电源10~30S使螺旋式电阻器发热,以加热进入汽缸的空气,提高柴油机在压缩终了时汽缸内的气体温度。
The device is powered by storage battery. Before starting, the power supply is switched on for 10 ~ 30s to heat the screw resistor, so as to heat the air entering the cylinder and increase the gas temperature in the cylinder when the compression is finished.
(5)用热水冲烫进气歧管即用热水冲烫进气歧管后,使进入汽缸的空气得到预热,以提高压缩终了时压缩空气的温度,
(5) Hot water is used to iron the intake manifold, that is, after hot water is used to iron the intake manifold, the air entering the cylinder is preheated to increase the temperature of the compressed air at the end of compression,
利于柴油着火燃烧。
It is good for diesel ignition.
(6)在油底壳安装螺旋式电阻器
(6) Install screw type resistor in oil pan
该电阻器可加热油底壳的机油,降低机油黏度,减小启动阻力。应用此种方法时,应控制加热时间,避免因加热时间过长,机油温度过高,而导致机油老化变质。
The resistor can heat the oil in the oil pan, reduce the viscosity of the oil and the starting resistance. When using this method, the heating time should be controlled to avoid oil aging and deterioration due to too long heating time and too high oil temperature.
