東莞艾科自動化設備有限公司是一家從事經(jīng)營國外進口液壓氣動備件,自動化儀表的貿(mào)易型公司;專注于現(xiàn)貨工業(yè)傳動自動化流體領域。主營產(chǎn)品電磁閥,調(diào)壓閥,伺服閥,高壓泵,油泵,放大器齒輪泵,柱塞泵,磁性開關(guān),液壓馬達。經(jīng)營品牌有:博世力士樂rexroth,美國VICKERS 意大利UNIVER 美國HUMPHEY 等進口品牌。下面是電磁閥相關(guān)選型參數(shù)
3、根據(jù)壓力參數(shù)選擇電磁閥的:原理和結(jié)構(gòu)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。
4、電氣選擇:電壓規(guī)格應盡量優(yōu)先選用AC220V、DC24最為方便
選型依據(jù)
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 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)。
選型依據(jù):
1、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(nèi)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。
2、根據(jù)流體參數(shù)選擇電磁閥的:材質(zhì)、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(zhì)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(jié)構(gòu)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。
3、根據(jù)壓力參數(shù)選擇電磁閥的:原理和結(jié)構(gòu)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。
4、電氣選擇:電壓規(guī)格應盡量優(yōu)先選用AC220V、DC24最為方便。
5、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)的時間多于關(guān)閉的時間應選 用常開型;
2)要是開啟的時間短或開和關(guān)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。
6、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。4WE6D62/EG220N9K4/V德國力士樂力士樂電磁閥示例展示如下,力士樂的除了能提供一串訂貨號過來,個別的產(chǎn)品要提供型號+訂貨號。
