柴油发电机组节温器的结构及维修方法
Diesel generator structure and repair the thermostat five method
1.节温器的布局与效果
Layout and effect of 1 thermostat
(1)节温器的布局特色
(1) the layout of thermostat
节温器是一个用黄铜皮制作的有折叠纹的圆筒,此圆筒装配在冲压而成的外壳中。圆筒内部装有易汽化的液体乙酷或酒精。波纹圆筒的一端有两个巨细不等的阀门。它通常装配在气缸盖出水管的接口处。
The thermostat is a made of brass skin with folding lines of the cylinder, the cylinder assembly in stamping and shell. Cylinder with internal easy vaporization of liquid ethylene cool or alcohol. One end of the corrugated cylinder with two different sizes of valves. It is usually mounted on the cylinder head water interface..

根据柴油机负荷的巨细和水温的高低自动改动流经散热器的水量,确保柴油机在最佳温度(80°C士5°C)下工作。
According to the load of the diesel engine and the size of the low water temperature automatic change through the water cooler, ensure that the diesel engine in the best temperature (80 ° C, 5 ° C) work.
2.节温器的工作原理
Working principle of 2 thermostat
柴油机机体内部水温低于70°C时,节温器的出水阀门封闭,冷却液全部经节温器的旁通阀门流田水泵的进口循环运用,这时冷却液只在水泵和水套中循环,称作小循环,如图6-7a所示。
Diesel engine body temperature below 70 ° C, the water outlet valve thermostat closed cycle cooling liquid, imported by all through the bypass valve thermostat flow field of pump, the cooling liquid in pump and water jacket in the cycle, called the small cycles, as shown in figure 6-7a.
柴油机机体内部水温在70oe~80oe时,节温器的旁通阀门逐步封闭,通往散热器的出水阀门逐步打开。此刻,机体内部的冷却液一有些仍进行小循环,另一有些冷却液经散热器回水管流回散热器。
Diesel engine internal temperature at 70oe~80oe, bypass valve thermostat gradually closed, the water valve to the radiator to gradually open. At the moment, th coolant inside the body of a still small cycling, back into the radiator the radiator coolant return pipe another some.
柴油机机体内部水温在80°C以上时,节温器旁通阅门完全封闭,出水阀门全部翻开。此刻,机体内部冷却液全部流经散热器进行大循环。
Diesel engine internal temperature above 80 ° C, thermostat by-pass read the door closed, the water outlet valve open. At the moment, the internal coolant through the radiator all proceed big circulation.
