贺德克开关压力开关空调压力开关是一个保护开关。在汽车上常用的是三态开关。 1.低压保护开关:当空调系统有泄漏或制冷剂少时,为了保护压缩机不损坏,而强行让压缩机停止工作; 2.中态开关:当冷凝压力偏高时,强行让冷凝风扇高速旋转,降低高压压力,增加冷却效果。 3.高压开关,为了防止系统压力太大,导致系统爆炸等强行让压缩机停止工作。当制冷剂被压缩成液态储存,贺德克压力开关保护空调系统正常运行,空调系统内制冷剂压力过高或过低时,压力开关断掉,从而使压缩机不工作(压力开关等开关控制继电器,从而控制压缩机),保护系统部件不损坏。汽车空调压力开关,一般分为两态压力开关和三态压力开关,压力开关是与压缩机、冷凝器电子扇或是水箱风扇相连接的,由汽车上的ECU控制,根据空调内的压力变化控制风扇的开启关闭,或风量大小,当压力过高时,压缩机便停止工作,达到保护系统的功能。http://www.china-hydac.com/027-87263542手机:18372021864ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" SANdbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C8%3A134217728%2C9%3A134250504%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=29.0.0&pra=5&wgl=1&dt=1614323407415&bpp=5&bdt=303&idt=21&shv=r20210224&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Da07b3c4ba002eaff-22ed306a0ec40076%3AT%3D1602729171%3ART%3D1602729171%3AS%3DALNI_MbBh5yg2uKd0UtH0u1Ylcdyq42wTg&nras=1&correlator=6400969786113&frm=23&ife=1&pv=2&ga_vid=950080444.1614323408&ga_sid=1614323408&ga_hid=1857031480&ga_fc=0&nhd=1&u_tz=480&u_his=6&u_java=0&u_h=1080&u_w=1920&u_ah=1030&u_aw=1920&u_cd=24&u_nplug=14&u_nmime=31&adx=-12245933&ady=-12245933&biw=1238&bih=600&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=44737537&oid=3&pvsid=1912653017170240&pem=217&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&rx=0&eae=2&fc=1664&brdim=0%2C0%2C0%2C0%2C1920%2C0%2C1920%2C1030%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=1&uci=1.fkvr1055tpfe&fsb=1&dtd=104" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.fkvr1055tpfe" data-load-complete="true"> |
