柴油發電機組節溫器的結構及維修方法
Diesel generator structure and repair the thermostat five method
1.節溫器的布局與效果

(1)節溫器的布局特色
(1) the layout of thermostat
節溫器是一個用黃銅皮制作的有折疊紋的圓筒,此圓筒裝配在沖壓而成的外殼中。圓筒內部裝有易汽化的液體乙酷或酒精。波紋圓筒的一端有兩個巨細不等的閥門。它通常裝配在氣缸蓋出水管的接口處。
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..

根據柴油機負荷的巨細和水溫的高低自動改動流經散熱器的水量,確保柴油機在最佳溫度(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.節溫器的工作原理
Working principle of 2 thermostat
柴油機機體內部水溫低于70°C時,節溫器的出水閥門封閉,冷卻液全部經節溫器的旁通閥門流田水泵的進口循環運用,這時冷卻液只在水泵和水套中循環,稱作小循環,如圖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.
柴油機機體內部水溫在70oe~80oe時,節溫器的旁通閥門逐步封閉,通往散熱器的出水閥門逐步打開。此刻,機體內部的冷卻液一有些仍進行小循環,另一有些冷卻液經散熱器回水管流回散熱器。
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.
柴油機機體內部水溫在80°C以上時,節溫器旁通閱門完全封閉,出水閥門全部翻開。此刻,機體內部冷卻液全部流經散熱器進行大循環。
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.
