燃气发电机冷却水温度高以及爆震现象分析

返回 2022.06.23 来源:http://www.huannengpower.com
大部分的机器设备一旦使用时间久了不可避免会出现各式的问题,比如说燃气发电机冷却水温度高以及爆震现象的存在,这就要赶紧进行分析原因了,以防止发生隐患。下面来讲讲吧。
Once most of the machines and equipment have been used for a long time, various problems will inevitably occur, such as high cooling water temperature of gas generator and the existence of detonation phenomenon. Therefore, it is necessary to analyze the causes to prevent hidden dangers. Let's talk about it.
冷却水温度高
High cooling water temperature
现象:站控值班人员发现燃气发电机水温偏高,相关人员随即赴现场对发电机组进行检查,风扇等冷却系统正常,控制面板无报警。半小时之后,上位机出现该燃气发电机冷却水温度高报警, 进而造成停机。
Phenomenon: when the station control personnel on duty found that the water temperature of the gas generator was too high, relevant personnel immediately went to the site to inspect the generator set. The cooling systems such as fans were normal, and the control panel did not give an alarm. Half an hour later, the upper computer gave an alarm of high cooling water temperature of the gas generator, resulting in shutdown.
造成此次冷却水温度高原因分析:该燃气发电机正常运行时冷却水温度在89℃左右,当负载有较大幅度的提升时,冷却水温度随即上升,超过临界值导致报警停机。
Cause analysis of the high cooling water temperature: the cooling water temperature of the gas generator is about 89 ℃ during normal operation. When the load is greatly increased, the cooling water temperature rises immediately, exceeding the critical value, resulting in alarm and shutdown.
其他原因分析:
Analysis of other causes:
(1)冷却水管路存在结垢现象,导致冷却水散热不佳;(2)冷却风扇电机损坏,导致散热不佳;(3)节温器卡住或者其他原因导致未打开;(4)冷却水管路或者接头处漏水,冷却水自然损耗液位降低导致冷却水缺失;(5)冷却水温度传感器故障,导致检测结果失准。
(1) Scaling of cooling water pipeline leads to poor cooling of cooling water; (2) The cooling fan motor is damaged, resulting in poor heat dissipation; (3) Thermostat is stuck or not opened due to other reasons; (4) There is water leakage in the cooling water pipeline or joint, and the natural loss of cooling water causes the loss of cooling water due to the decrease of liquid level; (5) The cooling water temperature sensor is faulty, resulting in inaccurate detection results.

爆震
knock
现象:现场控制屏出现“Knocking”故障报警信息。
Phenomenon: the "knocking" fault alarm message appears on the field control panel.
原因分析:
Cause analysis:
(1)气缸燃烧室内积碳过多,容易在积碳表面形成高温着火点;(2)点火提前角过于提前,导致点火引燃混合燃气的时间早于活塞到达上止点的时间,从而在活塞压缩冲程中压力急剧升高导致爆燃的发生。
(1) There is too much carbon in the cylinder combustion chamber, which is easy to form high-temperature ignition points on the carbon deposition surface; (2) The ignition advance angle is too early, which causes the ignition time of the mixed gas to be earlier than the time when the piston reaches the top dead center, so the pressure rises sharply in the piston compression stroke, resulting in the occurrence of deflagration.
同时,爆燃产生的压力作用于活塞,影响活塞的冲程,导致爆震现象;(3)燃气发电机组冷却水温度过高导致发动机机体温度高,散热不良,产生高温而发生爆震;(4)空燃比不正确等其他情况。
At the same time, the pressure produced by deflagration acts on the piston, affecting the piston stroke and leading to detonation; (3) Excessive cooling water temperature leads to high engine body temperature, poor heat dissipation, high temperature and detonation; (4) Other conditions such as incorrect air-fuel ratio.
