ASCO電磁閥的設計參數的分為幾部分?
ASCO電(dian)磁(ci)閥通電(dian)就(jiu)會產生(sheng)力(li)(li)(li)量(liang)(liang)(liang)(liang)(liang)(liang), 在(zai)相同(tong)(tong)(tong)功(gong)耗下(xia)(xia),不(bu)同(tong)(tong)(tong)大小的(de)行程(cheng)位置力(li)(li)(li)量(liang)(liang)(liang)(liang)(liang)(liang)的(de)大小不(bu)同(tong)(tong)(tong);在(zai)電(dian)磁(ci)鐵(tie)(tie)應(ying)(ying)用時,應(ying)(ying)考慮安全,即對力(li)(li)(li)量(liang)(liang)(liang)(liang)(liang)(liang)的(de)測試應(ying)(ying)是(shi)(shi)電(dian)磁(ci)鐵(tie)(tie)在(zai)定通電(dian)率下(xia)(xia),溫(wen)升穩定后(hou)所測得(de)的(de)力(li)(li)(li)量(liang)(liang)(liang)(liang)(liang)(liang)即為電(dian)磁(ci)鐵(tie)(tie)的(de)力(li)(li)(li)量(liang)(liang)(liang)(liang)(liang)(liang),在(zai)行程(cheng)相同(tong)(tong)(tong)情(qing)況下(xia)(xia),不(bu)同(tong)(tong)(tong)功(gong)耗力(li)(li)(li)量(liang)(liang)(liang)(liang)(liang)(liang)也(ye)會不(bu)同(tong)(tong)(tong);不(bu)同(tong)(tong)(tong)的(de)功(gong)耗對應(ying)(ying)不(bu)同(tong)(tong)(tong)通電(dian)率(既是(shi)(shi)占空比)。,般(ban)情(qing)況下(xia)(xia),初始力(li)(li)(li)量(liang)(liang)(liang)(liang)(liang)(liang)是(shi)(shi)溫(wen)升穩定后(hou)力(li)(li)(li)量(liang)(liang)(liang)(liang)(liang)(liang)的(de)1.5倍左右(you)。如產品的(de)通電(dian)率很低(只有幾(ji)次通斷,而且時間非常短)則可將安全系(xi)數降低1.2倍。通常規律是(shi)(shi):⑴行程(cheng)↑力(li)(li)(li)量(liang)(liang)(liang)(liang)(liang)(liang)↓(⑵功(gong)耗↑力(li)(li)(li)量(liang)(liang)(liang)(liang)(liang)(liang)↑。
ASCO電磁閥緣等
ASCO電磁閥工作溫升, 和工作時的環境溫度決定了電磁鐵需要的緣溫度等. 有以下等分類:
A=105℃, E=120℃, B=130℃, F=155℃, H=180℃, 200=200℃, 220=220℃, 250=250℃
ASCO電(dian)磁閥電(dian)源類型及功率
不同的輸入電流波形決定了電磁鐵的工作模式: 應用中可能有的是: 交流AC/直流DC (恒壓源, 恒流源, 電瓶, 干電池, DC 發電機, 電容), 整流濾波方式, 電壓范圍, zui大可供電流等因素利用二極管整流。
電磁鐵應用中, 交流ASCO電磁閥可以直接用交流電。直流電磁鐵則必須采用整流器轉換為直流. 輸出力量在定范圍內和電流(功率)成比例. 電磁鐵達到磁飽和后力量不再隨電流(功率)增大. 同樣, 溫升和電流(功率)成正比.
ASCO電磁閥的保護措施
如某些特殊場合,電磁鐵需要采用些必要的保護措施,如增加過熱保護,過流保護以及電磁鐵驅動控制電路的保護。
ASCO電磁閥環境因素和壽命
環境條件(jian)因素(su)(su) 以及 壽(shou)命需要 是(shi)在(zai)電磁鐵(tie)用料和表面處(chu)理(li)方式(shi)選(xuan)擇式(shi)的重要考(kao)慮因素(su)(su). 環境因素(su)(su)包括(kuo): 溫度(du), 濕度(du), 磁場或電場; 氣體, 液體和固(gu)體污(wu)染或腐(fu)蝕.沖擊震動, 振動
ASCO電磁(ci)閥通電率:
通(tong)(tong)(tong)(tong)電(dian)(dian)率(lv)(lv)的概(gai)念如(ru)下公式所示(shi)。即表示(shi)通(tong)(tong)(tong)(tong)電(dian)(dian)時(shi)(shi)(shi)(shi)間(jian)(On time)除以個(ge)(ge)周期的時(shi)(shi)(shi)(shi)間(jian)(On time + Off time),通(tong)(tong)(tong)(tong)電(dian)(dian)率(lv)(lv)的通(tong)(tong)(tong)(tong)俗叫法為占空比。例(li)如(ru):個(ge)(ge)電(dian)(dian)磁(ci)鐵(tie)的通(tong)(tong)(tong)(tong)電(dian)(dian)時(shi)(shi)(shi)(shi)間(jian)為1秒(miao)(miao),斷電(dian)(dian)時(shi)(shi)(shi)(shi)間(jian)為3秒(miao)(miao),那么它通(tong)(tong)(tong)(tong)電(dian)(dian)率(lv)(lv)就為 1/(1+3)=25%,通(tong)(tong)(tong)(tong)電(dian)(dian)率(lv)(lv)是個(ge)(ge)非常重要(yao)的參數,因(yin)為當電(dian)(dian)磁(ci)鐵(tie)被激勵是會導致線(xian)圈(quan)發(fa)熱,如(ru)果發(fa)熱過大會燒(shao)毀線(xian)圈(quan)。負載周期或者zui長通(tong)(tong)(tong)(tong)電(dian)(dian)時(shi)(shi)(shi)(shi)間(jian), 以及電(dian)(dian)磁(ci)鐵(tie)的功(gong)率(lv)(lv)和散熱決定了電(dian)(dian)磁(ci)鐵(tie)工作時(shi)(shi)(shi)(shi)的溫(wen)升,同時(shi)(shi)(shi)(shi)也決定了通(tong)(tong)(tong)(tong)電(dian)(dian)率(lv)(lv)。.
