YUKEN電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)的(de)主要(yao)特(te)點電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)外(wai)漏(lou)(lou)堵絕,內(nei)漏(lou)(lou)易(yi)控(kong),使用(yong)(yong)安(an)全(quan)。內(nei)外(wai)泄漏(lou)(lou)是危及安(an)全(quan)的(de)要(yao)素(su)。其它自 1控(kong)閥(fa)(fa)(fa)通常將(jiang)閥(fa)(fa)(fa)桿伸出,由(you)電(dian)(dian)(dian)動(dong)(dong)、氣動(dong)(dong)、液(ye)動(dong)(dong)執行機構(gou)控(kong)制閥(fa)(fa)(fa)芯(xin)的(de)轉動(dong)(dong)或移動(dong)(dong)。這(zhe)都要(yao)解決(jue)長期動(dong)(dong)作閥(fa)(fa)(fa)桿動(dong)(dong)密封(feng)的(de)外(wai)泄漏(lou)(lou)難題;唯有(you)電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)是用(yong)(yong)電(dian)(dian)(dian)磁(ci)力(li)作用(yong)(yong)于密封(feng)在(zai)(zai)電(dian)(dian)(dian)動(dong)(dong)調節閥(fa)(fa)(fa)隔(ge)磁(ci)套管內(nei)的(de)鐵芯(xin)完成,不(bu)存在(zai)(zai)動(dong)(dong)密封(feng),所以外(wai)漏(lou)(lou)易(yi)堵絕。電(dian)(dian)(dian)動(dong)(dong)閥(fa)(fa)(fa)力(li)矩控(kong)制不(bu)易(yi),容易(yi)產生(sheng)內(nei)漏(lou)(lou),甚至拉斷閥(fa)(fa)(fa)桿頭部;電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)的(de)結構(gou)型式容易(yi)控(kong)制內(nei)泄漏(lou)(lou),直至降為(wei)零(ling)。所以,電(dian)(dian)(dian)磁(ci)閥(fa)(fa)(fa)使用(yong)(yong)特(te)別安(an)全(quan),尤其適用(yong)(yong)于腐(fu)蝕性、有(you)毒或高低(di)溫(wen)的(de)介質。
電磁閥是工廠中常見的一類設備,它是用電磁來控制管道中流體介質(液壓油或壓縮空氣)的流動方向、流量及速度的設備。在控制系統中,它屬于執行機構。
電磁閥在使用時,有以下(xia)幾點需(xu)要注意:
1、要根(gen)據(ju)其應用(yong)環(huan)境(jing),選(xuan)擇合(he)適的電(dian)磁(ci)(ci)閥,不能混用(yong)。比(bi)如,要工作在腐蝕(shi)性較(jiao)強(qiang)的環(huan)境(jing)下,就(jiu)要選(xuan)擇耐腐蝕(shi)性的電(dian)磁(ci)(ci)閥;又(you)比(bi)如流經的流體粘度(du)較(jiao)大,就(jiu)要選(xuan)擇高粘度(du)的電(dian)磁(ci)(ci)閥。總之,電(dian)磁(ci)(ci)閥在使用(yong)前(qian)要正確選(xuan)型。
2、電磁閥(fa)(fa)必須正確(que)安裝(zhuang)。在安裝(zhuang)時(shi)要格外注(zhu)意閥(fa)(fa)體上的箭頭,要與介質流向(xiang)一致,管道中不允許(xu)有反向(xiang)壓差(cha)。
3、要(yao)(yao)注意電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)的(de)工作(zuo)電(dian)(dian)(dian)壓(ya)(ya)。電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)根據(ju)工作(zuo)電(dian)(dian)(dian)壓(ya)(ya)種類分為交(jiao)流電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)和直(zhi)流電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)。交(jiao)流一(yi)般為AC220V,直(zhi)流電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)一(yi)般為DC24V。要(yao)(yao)接入正確的(de)工作(zuo)電(dian)(dian)(dian)壓(ya)(ya),否則會燒(shao)壞線圈。同時,要(yao)(yao)保證其工作(zuo)電(dian)(dian)(dian)壓(ya)(ya)的(de)穩(wen)(wen)定性,一(yi)般交(jiao)流電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)工作(zuo)電(dian)(dian)(dian)壓(ya)(ya)的(de)允許偏(pian)差范圍為:-15%~+10%;直(zhi)流電(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)的(de)允許偏(pian)差為:+/- 10%。必要(yao)(yao)時,可采取穩(wen)(wen)壓(ya)(ya)措施。
4、電(dian)磁(ci)閥的(de)電(dian)氣(qi)插(cha)頭(tou)(tou)要與閥線圈可靠連接。閥插(cha)頭(tou)(tou)一般會(hui)配備緊固螺絲(si),要將(jiang)其(qi)插(cha)好,擰(ning)緊。否則(ze),機械振動(dong)等會(hui)引(yin)(yin)起插(cha)頭(tou)(tou)晃動(dong),導致閥的(de)工作電(dian)壓波動(dong),極有可能(neng)引(yin)(yin)起設備誤(wu)動(dong)作或電(dian)磁(ci)閥受損(sun)。
5、介質管(guan)道要保持清(qing)潔、無雜質。否則會導致電磁閥(fa)閥(fa)芯(xin)卡頓,設備動(dong)作異常。一(yi)般,應該(gai)在閥(fa)前(qian)安裝過濾器,并(bing)定期清(qing)理、更(geng)換過濾網。
