ASCO電磁閥選型首先應該依次遵循安全性,可靠性,適用性,經(jīng)濟性四大原 電磁閥則,其次是根據(jù)六個方面的現(xiàn)場工況(即管道參數(shù)、流體參數(shù)、壓力參數(shù)、電氣參數(shù)、動作方式、特殊要求進行選擇)。
ASCO電磁閥選型依據(jù):
一、根據(jù)管道參數(shù)選擇電磁閥的:通徑規(guī)格(即DN)、接口方式
1、按照現(xiàn)場管道內徑尺寸或流量要求來確定通徑(DN)尺寸。
2、接口方式,一般>DN50要選擇法蘭接口,≤DN50則可根據(jù)用戶需要自由選擇。
ASCO電磁閥二、根據(jù)流體參數(shù)選擇電磁閥的:材質、溫度組
1、腐蝕性流體:宜選用耐腐蝕電磁閥和全不銹鋼;食用超凈流體:宜選用食品級不銹鋼材質電磁閥。
2、高溫流體:要選擇采用耐高溫的電工材料和密封材料制造的電磁閥,而且要選擇活塞式結構類型的。 電磁閥3、流體狀態(tài):大至有氣態(tài),液態(tài)或混合狀態(tài),特別是口徑大于DN25訂貨時一定要區(qū)分開來。
4、流體粘度:通常在50cSt以下可任意選擇,若超過此值,則要選用高粘度電磁閥。
ASCO電磁閥三、根據(jù)壓力參數(shù)選擇電磁閥的:原理和結構品種
1、公稱壓力:這個參數(shù)與其它通用閥門的含義是一樣的,是根據(jù)管道公稱壓力來定。
2、工作壓力:如果工作壓力低則必須選用直動或分步直動式原理;zui低工作壓差在0.04Mpa以上時直動式、分步直動式、先導式均可選用。
ASCO電磁閥四、電氣選擇:電壓規(guī)格應盡量優(yōu)先選用AC220V、DC24較為方便。
ASCO電磁閥五、根據(jù)持續(xù)工作時間長短來選擇:常閉、常開、或可持續(xù)通電
1、當電磁閥需要長時間開啟,并且持續(xù)的時間多余關閉的時間應選 電磁閥用常開型。
2、要是開啟的時間短或開和關的時間不多時,則選常閉型。
3、但是有些用于安全保護的工況,如爐、窯火焰監(jiān)測,則不能選常開的,應選可長期通電型。
ASCO電磁閥六、根據(jù)環(huán)境要求選擇輔助功能:防爆、止回、手動、防水霧、水淋、潛水
1、爆炸性環(huán)境:必須選用相應防爆等級的電磁閥(我公司現(xiàn)有:d II BT4、d II CT5、Ex m I/II T4) 。
2、當管內流體有倒流現(xiàn)象時,可選擇我公司OK71-N、OK72-N系列帶止回功能電磁閥。
3、當需要對電磁閥進行現(xiàn)場人工操作時,可選擇我公司OK71-S、OK72-S系列帶手動功能電磁閥。
4、露天安裝或粉塵多場合應選用防水,防塵品種(防護等級在IP54以上)。
5、用于噴泉必須采用潛水型電磁閥(防護等級在IP68以上)。
