HAWE原裝產品電磁閥價格好,質量更多,原裝產品,德國品質放心使用。 HAWE電磁閥從原理上分為三大類: 直動(dong)式電磁閥原理(li):通(tong)電(dian)時,電(dian)磁線圈產生電(dian)磁力把(ba)關(guan)閉(bi)件從閥座(zuo)上提起,閥門打(da)開;斷電(dian)時,電(dian)磁力消失,彈(dan)簧把(ba)關(guan)閉(bi)件壓在閥座(zuo)上,閥門關(guan)閉(bi)。 特點:在真空(kong)、負壓、零(ling)壓時(shi)能正(zheng)常工作,但(dan)通徑一般不超過25mm。 分步直動式電磁(ci)閥原理:它是一種直(zhi)動(dong)和先導式相結合的原理,當入口(kou)(kou)與出口(kou)(kou)沒有壓(ya)差時,通電(dian)(dian)后,電(dian)(dian)磁力(li)直(zhi)接把先導小閥(fa)(fa)和主(zhu)閥(fa)(fa)關(guan)閉件(jian)依次(ci)向(xiang)上提起(qi),閥(fa)(fa)門(men)打開。當入口(kou)(kou)與出口(kou)(kou)達到啟(qi)動(dong)壓(ya)差時,通電(dian)(dian)后,電(dian)(dian)磁力(li)先導小閥(fa)(fa),主(zhu)閥(fa)(fa)下(xia)腔壓(ya)力(li)上升,上腔壓(ya)力(li)下(xia)降,從(cong)而利用壓(ya)差把主(zhu)閥(fa)(fa)向(xiang)上推開;斷(duan)電(dian)(dian)時,先導閥(fa)(fa)利用彈簧力(li)或介質壓(ya)力(li)推動(dong)關(guan)閉件(jian),向(xiang)下(xia)移(yi)動(dong),使閥(fa)(fa)門(men)關(guan)閉。 特點(dian):在零壓差(cha)或(huo)真(zhen)空、高(gao)壓時亦(yi)能(neng)可*動作,但功率較大,要求必須(xu)水平安裝。 先(xian)導式電磁閥原理:通(tong)電時(shi),電磁(ci)力(li)把(ba)先導孔打開(kai),上腔室(shi)壓(ya)(ya)(ya)力(li)迅(xun)速下(xia)降,在(zai)關(guan) 閉(bi)件(jian)周(zhou)圍形成上低(di)下(xia)高(gao)的壓(ya)(ya)(ya)差,流體壓(ya)(ya)(ya)力(li)推動(dong)關(guan)閉(bi)件(jian)向(xiang)上移動(dong),閥(fa)(fa)門打開(kai);斷電時(shi),彈簧力(li)把(ba)先導孔關(guan)閉(bi),入口壓(ya)(ya)(ya)力(li)通(tong)過旁通(tong)孔迅(xun)速腔室(shi)在(zai)關(guan)閥(fa)(fa)件(jian)周(zhou)圍形成下(xia)低(di)上高(gao)的壓(ya)(ya)(ya)差,流體壓(ya)(ya)(ya)力(li)推動(dong)關(guan)閉(bi)件(jian)向(xiang)下(xia)移動(dong),關(guan)閉(bi)閥(fa)(fa)門。 特點:流(liu)體(ti)壓(ya)(ya)力范圍上(shang)限較(jiao)高,可任(ren)意安裝(需定制)但必須滿足(zu)流(liu)體(ti)壓(ya)(ya)差條(tiao)件。 2、電磁閥從閥結構(gou)(gou)和材料(liao)上的(de)不同與原理上的(de)區別,分為六個分支小類:直動膜片(pian)結構(gou)(gou)、分步(bu)直動膜片(pian)結構(gou)(gou)、先導膜片(pian)結構(gou)(gou)、直動活塞(sai)(sai)結構(gou)(gou)、分步(bu)直動活塞(sai)(sai)結構(gou)(gou)、先導活塞(sai)(sai)結構(gou)(gou)。 3、電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)按照功能分類:水用(yong)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、蒸汽電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、制冷電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、低溫電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、燃氣電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、消防電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、氨(an)用(yong)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、氣體電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、液(ye)體電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、微型電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、脈沖(chong)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、液(ye)壓(ya)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa) 常開電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、油用(yong)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、直流電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、高壓(ya)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)、防爆電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)(ci)閥(fa)(fa)(fa)(fa)等(deng)。 HAWE電磁閥安裝注意: 1、安(an)(an)裝(zhuang)時應(ying)注意(yi)閥(fa)體上(shang)箭頭應(ying)與介質(zhi)流向*。不可裝(zhuang)在有(you)直接滴水(shui)或濺水(shui)的地方。電磁(ci)閥(fa)應(ying)垂直向上(shang)安(an)(an)裝(zhuang); 2、電(dian)(dian)磁閥應保證在電(dian)(dian)源電(dian)(dian)壓(ya)為額定電(dian)(dian)壓(ya)的15%-10%波動(dong)范圍內正(zheng)常工作; 3、電(dian)磁閥安裝后,管道中不得有(you)反向壓差。并需(xu)通電(dian)數次,使(shi)之適(shi)溫后方可正式投入使(shi)用; 4、電磁閥(fa)安裝前應(ying)(ying)*清洗管道。通入的介質應(ying)(ying)無雜質。閥(fa)前裝過(guo)濾器; 5、當(dang)電磁閥(fa)發生故障或(huo)清洗時,為保證(zheng)系統繼續(xu)運(yun)行,應安裝(zhuang)旁(pang)路(lu)裝(zhuang)置。 HAWE電磁閥選用要點: 1)電磁(ci)閥(fa)選用主要(yao)控制參數(shu)為通徑、設(she)計(ji)公稱壓力(li)、介質允(yun)許溫度范圍、接口尺寸(cun)等。 2)電磁閥是用(yong)電磁鐵推動閥門的(de)開啟與關閉,通常用(yong)于口徑在(zai)40mm以下的(de)兩(liang)位式控制中,尤其(qi)多(duo)用(yong)于接通、切斷或轉換氣路(lu)、液路(lu)等。 3)閥(fa)門(men)的(de)(de)密封(feng)性能(neng)是(shi)考核(he)閥(fa)門(men)質量優劣的(de)(de)主(zhu)要指標之一。閥(fa)門(men)的(de)(de)密封(feng)性能(neng)主(zhu)要包括兩個方面(mian),即內(nei)漏和外漏。內(nei)漏是(shi)指閥(fa)座與關閉件之間對介質達到的(de)(de)密封(feng)程度。外漏是(shi)指閥(fa)桿填料部位的(de)(de)泄露,中(zhong)口墊(dian)片部位的(de)(de)泄露以及閥(fa)體因鑄造缺陷造成的(de)(de)泄露。外漏是(shi)不允許發生的(de)(de)。 4)電(dian)磁(ci)閥主要(yao)優(you)點是體(ti)積小(xiao),動作可(ke)靠(kao),維修方便,價格便宜。選(xuan)擇(ze)時需要(yao)注(zhu)意(yi)根據工藝要(yao)求選(xuan)擇(ze)常(chang)開或常(chang)閉(bi)型(xing)。 上海維特銳(rui)歐美日(ri)意工控(kong)產品優勢: 1、歐美辦(ban)事(shi)處(chu)原(yuan)廠拿報(bao)價,省去許多(duo)經銷代理商(shang)的中間環(huan)節(jie),給您提(ti)供(gong)高性價比產品 2、保(bao)證* 3、報價快、價格低、產(chan)品優。 4、貨(huo)期(qi)準;接(jie)到訂單(dan)我們(men)會(hui)*時間和廠(chang)家溝通確認貨(huo)期(qi),對有變更(geng)的貨(huo)期(qi)*時間反饋(kui)給客戶。 5、物流成本低;在(zai)國際貿易(yi)中,物流成本往往會決定產品的(de)整體價格,我們在(zai)德國倉庫統(tong)一驗貨包裝,然(ran)后報關拼箱發貨,空運(yun)到(dao)中國(guo),既確(que)保了發貨無誤,也降低了您(nin)的采購(gou)成本。 公司現貨: 歐姆龍 SS-5GL(微動開關) 20 MOOG D661-4651 1 ICAR "Typ MLR 25 PRL 45 20 2551/I-MK SH,2μF ±5%, 400V DB-A-30.000h " 10 穆格 G761-3002B 1 EDS345-1-016-000 EDS345-1-250-000 EDS346-1-250-000 EDS346-2-016-000 HDA4745-A-400-000 HDA4744-A-016-000 HDA4744-A-400-000 HDA4445-A-016-000 HDA4445-A-250-000 此信息版權歸上海維特銳所有,如需了解更多詳情,請點擊: 德國HAWE哈威(wei) |
