1、工作壽命,此項(xiàng)不列入出廠試驗(yàn)項(xiàng)目,屬于型式試驗(yàn)項(xiàng)目。為確保質(zhì)量應(yīng)選正規(guī)價(jià)格的產(chǎn)品。
2、工作制式:分長(zhǎng)期工作制,反復(fù)短時(shí)工作制和短時(shí)工作制三種。本公司常規(guī)產(chǎn)品均為長(zhǎng)期工作制,即線圈允許長(zhǎng)期通電工作。對(duì)于長(zhǎng)時(shí)間閥門開通只有短時(shí)關(guān)閉的情況,則宜選用常開電磁閥。用在短時(shí)工作制而批量又很大時(shí),可作特殊訂貨以降低功耗。?
3、工作頻率:動(dòng)作頻率要求高時(shí),結(jié)構(gòu)應(yīng)優(yōu)選直動(dòng)式電磁閥,電源聽優(yōu)選交流。
4、動(dòng)作可靠性嚴(yán)格地來(lái)說(shuō)此項(xiàng)試驗(yàn)尚未正式列入我國(guó)電磁閥專業(yè)標(biāo)準(zhǔn),為確保質(zhì)量應(yīng)選正規(guī)價(jià)格的產(chǎn)品。有些場(chǎng)合動(dòng)作次數(shù)并不多,但對(duì)可靠性要求卻很高,如消防、緊急保護(hù)等,切不可掉以輕心。特別重要的,還應(yīng)采取兩只連用雙保險(xiǎn)。
NUMATICS電磁閥是用電磁控制的工業(yè)設(shè)備,用在工業(yè)控制系統(tǒng)中調(diào)整介質(zhì)的方向、流量、速度和其他的參數(shù)。制冷電磁閥出現(xiàn)故障應(yīng)該怎么辦制冷電磁閥故障原因以及解決方法匯總,希望能為您提供幫助。
美國(guó)NUMATICS電磁閥選型要點(diǎn)-經(jīng)濟(jì)性:NUMATICS電磁閥ASCO總代理
不經(jīng)濟(jì)就是對(duì)資金,精力乃至生命的浪費(fèi)它選用的尺度之一,但必須是在安全、適用、可靠的基礎(chǔ)上的經(jīng)濟(jì)、經(jīng)濟(jì)性不單是產(chǎn)品的售價(jià),更要優(yōu)先考慮其功能和質(zhì)量以及安裝維修及其它附件所需用費(fèi)用、更重要的是,一只電磁閥在整個(gè)自控系統(tǒng)中在整個(gè)自控系統(tǒng)中乃至生產(chǎn)線中所占成本微乎其微,如果貪圖小便宜而錯(cuò)選早造成損害群是巨大的。
總之,經(jīng)濟(jì)性不單指產(chǎn)品價(jià)格,而是產(chǎn)品的性能價(jià)格比綜合費(fèi)用價(jià)格比。
排除方法:檢查電源接線是否不良→重新接線和接插件的連接,檢查電源電壓是否在±工作范圍-→調(diào)致正常位置范圍,線圈是否脫焊→重新焊接線圈短路→更換線圈,工作壓差是否不合適→調(diào)整壓差→或更換相稱的電磁閥,流體溫度過(guò)高→更換相稱的電磁閥,有雜質(zhì)使電磁閥的主閥芯和動(dòng)鐵芯卡死→進(jìn)行清洗,如有密封損壞應(yīng)更換密封并安裝過(guò)濾器,液體粘度太大,頻率太高和壽命已到→更換產(chǎn)品
故障現(xiàn)象二:NUMATICS電磁閥不能關(guān)閉
排除方法:主閥芯或鐵動(dòng)芯的密封件已損壞→更換密封件,流體溫度、粘度是否過(guò)高→更換對(duì)口的電磁閥,有雜質(zhì)進(jìn)入電磁閥產(chǎn)閥芯或動(dòng)鐵芯→進(jìn)行清洗,彈簧壽命已到或變形→更換,節(jié)流孔平衡孔堵塞→及時(shí)清洗,工作頻率太高或壽命已到→改選產(chǎn)品或更新產(chǎn)品
