我們來說一下節(jié)溫器的小知識。節(jié)溫器分為電子節(jié)溫器和石蠟節(jié)溫器，電子節(jié)溫器是近幾年才應(yīng)用的，是通過電來控制。很多車依然使用的是老式石蠟節(jié)溫器，是通過節(jié)溫器內(nèi)部石蠟的熱脹冷縮實(shí)現(xiàn)工作的。電子節(jié)溫器壞了會有故障碼，用解碼器可以很快查出來。而石蠟節(jié)溫器沒有電子部件，靠的全是機(jī)械裝置，因此壞了也不會有故障碼產(chǎn)生。要判斷是否損壞，需要知道它的工作原理，還要靠一定的經(jīng)驗(yàn)。 </p> <p> 節(jié)溫器安裝在水道中，作用是控制冷卻液的大小循環(huán)。冷卻液循環(huán)水道分為兩條，一條是只在發(fā)動機(jī)內(nèi)部循環(huán)，稱為小循環(huán)。另一條是從發(fā)動機(jī)出來經(jīng)過水箱冷卻再進(jìn)入發(fā)動機(jī)，稱為大循環(huán)。在大小循環(huán)的岔路口上裝著節(jié)溫器。節(jié)溫器關(guān)閉，冷卻水就出不來，只能進(jìn)行小循環(huán)，節(jié)溫器打開，冷卻水就可以出來，進(jìn)行大循環(huán)。節(jié)溫器一般在水溫80度時開始慢慢打開，到了103度時完全打開。節(jié)溫器缺點(diǎn)是節(jié)溫器在工作時經(jīng)常開閉，產(chǎn)生振蕩現(xiàn)象。福建柴油機(jī)閥芯</p><p style="text-indent:25px">馬克MAK柴油機(jī)溫控閥芯。廣西資陽機(jī)車柴油機(jī)閥芯</p><p> 節(jié)溫器是根據(jù)冷卻水溫度的高低自動調(diào)節(jié)進(jìn)入散熱器的水量，改變水的循環(huán)范圍，以調(diào)節(jié)冷卻系的散熱能力，保證發(fā)動機(jī)在合適的溫度范圍內(nèi)工作。 </p> <p> <p> 節(jié)溫器必須保持良好的技術(shù)狀態(tài)，否則會嚴(yán)重影響發(fā)動機(jī)的正常工作。如節(jié)溫器主閥門開啟過遲，就會引起發(fā)動機(jī)過熱；主閥門開啟過早，則使發(fā)動機(jī)預(yù)熱時間延長，使發(fā)動機(jī)溫度過低。 </p> <p> 水泵返回發(fā)動機(jī)，進(jìn)行發(fā)動機(jī)內(nèi)小循環(huán)。當(dāng)冷卻液溫度達(dá)到規(guī)定值后，石蠟開始融化逐漸變?yōu)橐后w，體積隨之增大并壓迫橡膠管使其收縮。在橡膠管收縮的同時對推桿作用以向上的推力，推桿對閥門有向下的反推力使閥門開啟。這時冷卻液經(jīng)由散熱器和節(jié)溫器閥，再經(jīng)水泵流回發(fā)動機(jī)，進(jìn)行大循環(huán)。節(jié)溫器大多數(shù)布置在汽缸蓋出水管路中，這樣的優(yōu)點(diǎn)是結(jié)構(gòu)簡單，容易排出冷卻系統(tǒng)中的氣泡；缺點(diǎn)是節(jié)溫器在工作時經(jīng)常開閉，產(chǎn)生振蕩現(xiàn)象。
