判断节温器是否故障办法很简单

来源:http://www.jnrunao.com/ 日期:2021-07-29 发布人:runao
很多车主在发动机出现问题后,总是以为是发动机内部故障,其实有时并不是因为发动机内部故障,也可能是节温器坏了,然后导致发动机无法在合适的温度下工作,导致发动机也出现异常,今天我就给大家说说节温器坏了什么症状,让你们了解一下节温器这个问题。
Many car owners always think that it is an internal fault of the engine after the engine has a problem. In fact, sometimes it is not because of the internal fault of the engine, but also because the thermostat is broken, which makes the engine unable to work at the appropriate temperature and leads to abnormal engine. Today I'll tell you what the symptoms of the thermostat are broken, Let you know about thermostat.
1、冷车启动后,打开散热器加水口盖,若散热器内冷却液平静,则表明节温器工作正常,如果冷却液不平静则表明节温器故障。这是因为在水温低于70℃时,节温器膨胀筒处于收缩状态,主阀门关闭;当水温高于80℃时,膨胀筒膨胀,主阀门渐渐打开,散热器内循环水开始流动。当水温表指示70℃以下时,散热器进水管处若有水流动,水温温热,则表时节温器主阀门关闭不严,使冷却水过早大循环。
1. After the cold start, open the radiator water filler cap. If the coolant in the radiator is calm, it indicates that the thermostat is working normally. If the coolant is not calm, it indicates that the thermostat is faulty. This is because when the water temperature is lower than 70 ℃, the expansion cylinder of thermostat is in contraction state and the main valve is closed; When the water temperature is higher than 80 ℃, the expansion cylinder expands, the main valve gradually opens, and the circulating water in the radiator begins to flow. When the water temperature gauge indicates below 70 ℃, if there is water flowing at the radiator inlet pipe and the water temperature is warm, the main valve of the thermometer is not closed tightly, resulting in premature large circulation of cooling water.
2、当发动机开始冷车运转时,水箱的上水室进水管处还有冷却水流出,则说明节温器的主阀门不能关闭;当发动机冷却液温度超过70度时,水箱的上水室进水管处无冷却水流出,则说明节温器主阀门不能正常开启,这是就是节温器损坏需要修理了。
2. When the engine starts cold running, there is still cooling water flowing out of the water inlet pipe of the upper water chamber of the water tank, which indicates that the main valve of the thermostat cannot be closed; When the engine coolant temperature exceeds 70 ℃, and there is no cooling water flowing out of the water inlet pipe of the upper water chamber of the water tank, it indicates that the main valve of the thermostat cannot be opened normally, which means that the thermostat is damaged and needs to be repaired.
节温器的更换
Thermostat replacement
知道了节温器坏了什么症状后,就应该了解一下节温器什么时候更换一次了,一般的蜡式节温器的安全寿命是50000KM汽车行驶里程,所以需要在汽车行驶50000KM就需要更换节温器;或是在温度可调试恒温加热设备检查节温器主阀门的开启温度、全开温度及升程,其中有一项不符合规范定值,就需要更换节温器。
After knowing the symptoms of thermostat failure, you should know when the thermostat is replaced. The safety life of general wax thermostat is 50000km, so the thermostat needs to be replaced when the car runs 50000km; Or the thermostatic heating equipment can be debugged at the temperature to check the opening temperature, full opening temperature and lift of the main valve of the thermostat. If one of them does not meet the specified value, the thermostat needs to be replaced.
其实节温器坏了什么症状很明显,就是在冷车的时候启动后,看冷却液是否平静,不平静则是节温器故障,平静则是节温器正常,但是平时也得注意定期去检查一下节温器,避免造成发动机收到影响而导致拉缸或者损坏
In fact, the symptoms of thermostat failure are obvious. After starting when the car is cold, check whether the coolant is calm. If it is not calm, it is the thermostat failure. If it is calm, it is the thermostat normal. However, at ordinary times, you should also pay attention to regularly check the thermostat to avoid cylinder pulling or damage caused by the impact of the engine
