What we need to pay special attention to is the use of gas generator set. As a large-scale power generation equipment, correct operation is very important. If gas generator set encounters high temperature operation, what to do? Need overhaul?
What is the reason of high temperature operation of gas generator set?
1. External accessories of radiator
The sundries attached to the surface of radiator will reduce the heat dissipation area of radiator, and the area against the wind of radiator will reduce, which will lead to the decrease of heat dissipation capacity of radiator, resulting in high temperature gas accumulation generator set.
2. Poor coolant circulation
恒温器开度低，会降低济柴燃气发电机组大循环冷却系统的冷却能力。假设济柴燃气发电机组温度较高，则可以将恒温器放入水中加热。恒温器的开启间距一般为8 ~ 10mm。
The low opening of thermostat will reduce the cooling capacity of large cycle cooling system of jichai gas-fired generator. If the temperature of jichai gas generator is high, the thermostat can be put into water for heating. The opening space of thermostat is generally 8 ~ 10 mm.
3. Insufficient coolant
If there is a lack of cooling system coolant jichai natural gas generator set, it will affect the heat dissipation of jichai natural gas generator set and jichai constitutes a high temperature gas generator set. In this regard, the radiator and expansion tank coolant should be checked frequently, and the low level should be supplemented in time. Other common faults are: service life of low concentration gas generator set; Troubleshooting of gas generator set.
4. The fan belt is too loose or the fan is deformed电动风扇皮带太松,短暂的风扇转速下降,散热器不能玩由于散热,导致机器温度高jichai天然气发电机组。此外,电风扇变形也会导致散热器散热人才不能充分发挥。对此，有必要及时检查济柴燃气发电机组风机皮带是否松动，风机形状是否异常。
The electric fan belt is too loose, the fan speed drops for a short time, and the radiator can not play due to heat dissipation, resulting in high machine temperature jichai natural gas generator set. In addition, the deformation of the electric fan will also lead to the radiator cooling personnel can not fully play. Therefore, it is necessary to check whether the fan belt of jichai gas generator unit is loose and whether the fan shape is abnormal.
5. Long time overload work
The long-term overload operation of gas generator will increase its fuel consumption and heat load, and then the water temperature will be too high. Therefore, long-term overload should be avoided.
If the power of gas generator unit is obviously reduced. When the throttle valve is in the maximum position, the maximum output power of the gas turbine is only about 60% of the rated power, obviously there is no moving configuration load. After maintenance and adjustment, the power of related components such as fuel oil, gas distribution mechanism, crankshaft and connecting rod mechanism cannot be recovered.
