如何控制温度开关?
编辑:杭州有限公司   时间:2022-08-19

  在使用(yong)温(wen)控器的(de)(de)时候,可能会(hui)出(chu)现开(kai)关失(shi)效(xiao)的(de)(de)情(qing)况,一旦出(chu)现这样的(de)(de)问题,会(hui)形成(cheng)很(hen)大(da)后(hou)患,所(suo)以J9九游会AG 需要了解到怎(zen)样快速的(de)(de)诊断出(chu)温(wen)度开(kai)关失(shi)效(xiao)的(de)(de)原因。

  J9九游会AG 都知道奥迪、桑塔纳轿车的冷却电扇由两个部分控制:一是由温度开关控制,当散热器水温达到95℃时,电扇低速转动;当散热器水温达到105℃时,电扇全速转动。二是由空调开关控制,当使用空调时,不论水温凹凸,电扇均是全速转动。

  遇到(dao)上述故障时(shi),如(ru)果(guo)是夏(xia)季行(xing)(xing)(xing)(xing)车(che),打开(kai)(kai)空(kong)调(diao)(diao)开(kai)(kai)关(guan),冷却电扇当即转动,标明温(wen)控开(kai)(kai)关(guan)失效,此刻可不(bu)再采取其(qi)他办法,继续行(xing)(xing)(xing)(xing)车(che)。如(ru)果(guo)是春秋季,天(tian)气(qi)比(bi)较(jiao)暖和(he)时(shi)行(xing)(xing)(xing)(xing)车(che),也可打开(kai)(kai)空(kong)调(diao)(diao)开(kai)(kai)关(guan),不(bu)开(kai)(kai)室内(nei)电扇,拔掉(diao)空(kong)调(diao)(diao)压缩机电磁离合器的电线插头,并简略包好(hao)以(yi)防(fang)搭铁短路,这样仍可以(yi)继续行(xing)(xing)(xing)(xing)驶(shi),便(bian)要注意水温(wen)表指示(shi)的温(wen)度,并用空(kong)调(diao)(diao)开(kai)(kai)关(guan)来调(diao)(diao)节(jie)。

  把温(wen)(wen)(wen)(wen)(wen)(wen)控(kong)器夹在(zai)测验(yan)(yan)区(qu)(qu)内,等待测温(wen)(wen)(wen)(wen)(wen)(wen)区(qu)(qu)的温(wen)(wen)(wen)(wen)(wen)(wen)度平衡后(hou),开端测验(yan)(yan)。测验(yan)(yan)炉内以空气作(zuo)为加热(re)介质,在(zai)测温(wen)(wen)(wen)(wen)(wen)(wen)区(qu)(qu)放置(zhi)(zhi)温(wen)(wen)(wen)(wen)(wen)(wen)度计或温(wen)(wen)(wen)(wen)(wen)(wen)度传感(gan)器。在(zai)温(wen)(wen)(wen)(wen)(wen)(wen)度进入动作(zuo)温(wen)(wen)(wen)(wen)(wen)(wen)度公(gong)役范围(wei)前(qian)2K开端,以小于1K/min的温(wen)(wen)(wen)(wen)(wen)(wen)度变(bian)化速(su)率进行加温(wen)(wen)(wen)(wen)(wen)(wen)或降(jiang)温(wen)(wen)(wen)(wen)(wen)(wen),其间必须(xu)进行拌(ban)和,使温(wen)(wen)(wen)(wen)(wen)(wen)度散布(bu)充分均匀;测温(wen)(wen)(wen)(wen)(wen)(wen)区(qu)(qu)温(wen)(wen)(wen)(wen)(wen)(wen)度散布(bu)均匀性在(zai)±0.4K以内。测验(yan)(yan)装(zhuang)置(zhi)(zhi)可设置(zhi)(zhi)通断显示(shi)装(zhuang)置(zhi)(zhi)。温(wen)(wen)(wen)(wen)(wen)(wen)控(kong)器两接(jie)线端子(zi)间电压大(da)于5V,通过试样(yang)电流大(da)于10mA。
