德國FESTO電磁閥的調節精度限制是多少？

FESTO電磁(ci)閥(fa)(fa)調(diao)節(jie)精(jing)(jing)度(du)受限，適(shi)(shi)(shi)用介質(zhi)受限。FESTO電磁(ci)閥(fa)(fa)通(tong)常只(zhi)有開(kai)關兩種(zhong)狀(zhuang)態，閥(fa)(fa)芯只(zhi)能(neng)處于(yu)(yu)兩個極(ji)限位置(zhi)，不能(neng)連(lian)續調(diao)節(jie)，（力圖突(tu)破(po)的(de)新構思不少，但還都處于(yu)(yu)試(shi)驗試(shi)用階段）所以(yi)調(diao)節(jie)精(jing)(jing)度(du)還受到一定(ding)限制(zhi)。FESTO電磁(ci)閥(fa)(fa)對(dui)(dui)介質(zhi)潔凈度(du)有較高要(yao)求，含顆粒狀(zhuang)的(de)介質(zhi)不能(neng)適(shi)(shi)(shi)用，如屬雜質(zhi)須(xu)先濾去。另(ling)外，粘稠狀(zhuang)介質(zhi)不能(neng)適(shi)(shi)(shi)用，而(er)且，特(te)定(ding)的(de)產(chan)品(pin)適(shi)(shi)(shi)用的(de)介質(zhi)粘度(du)范圍相對(dui)(dui)較窄。FESTO電磁(ci)閥(fa)(fa)型號多(duo)樣(yang)，用途廣泛(fan)。

FESTO電磁閥結構：

FESTO電磁閥包括（線圈(quan)、磁鐵、頂(ding)桿）。

當線圈接(jie)通電(dian)流(liu)，便產生了(le)(le)磁(ci)(ci)性，跟(gen)磁(ci)(ci)鐵(tie)(tie)相互吸引，磁(ci)(ci)鐵(tie)(tie)就(jiu)會拉(la)動(dong)頂桿(gan)。關閉(bi)電(dian)源，磁(ci)(ci)鐵(tie)(tie)和頂桿(gan)就(jiu)復位了(le)(le)，這樣FESTO電(dian)磁(ci)(ci)閥就(jiu)完成了(le)(le)作功過程。這就(jiu)是(shi)FESTO電(dian)磁(ci)(ci)閥的工作原理。

FESTO電磁閥(fa)一般用于液(ye)壓系統，來關閉和開通油路。

實際上，根據(ju)流(liu)過(guo)介(jie)質的(de)溫(wen)度，壓(ya)力等(deng)情況(kuang)，比如管道有壓(ya)力和自流(liu)狀態無壓(ya)力。FESTO電(dian)磁閥的(de)工作(zuo)原理是不同的(de)。

比(bi)如在自(zi)流狀態下(xia)需要零(ling)壓啟動的(de)，就(jiu)是通電(dian)后，線圈(quan)整(zheng)個(ge)(ge)把閘(zha)體吸起來(lai)(lai)。而有壓力狀態的(de)FESTO電(dian)磁閥，則是線圈(quan)通電(dian)后吸出(chu)插在閘(zha)體上(shang)的(de)一個(ge)(ge)銷子，用流體自(zi)身的(de)壓力把閘(zha)體頂起來(lai)(lai)。

這兩種(zhong)方式的(de)不(bu)同(tong)之處是，自流狀態(tai)的(de)FESTO電(dian)磁閥(fa)，因為線圈要(yao)吸(xi)起整個閘體，所(suo)以(yi)體積較大(da)而帶(dai)壓狀態(tai)的(de)FESTO電(dian)磁閥(fa)，只需(xu)要(yao)吸(xi)起銷(xiao)子(zi)，所(suo)以(yi)體積可以(yi)做(zuo)的(de)比較小。

FESTO電磁閥分類：

追朔FESTO電磁閥(fa)(fa)的(de)發展史，到目前(qian)為(wei)止，國內外的(de)FESTO電磁閥(fa)(fa)從(cong)(cong)原(yuan)理上分(fen)為(wei)三大(da)類(即：直動式、分(fen)步(bu)童先(xian)導式)，而從(cong)(cong)閥(fa)(fa)瓣結(jie)(jie)(jie)構(gou)和材料(liao)上的(de)不同與(yu)原(yuan)理上的(de)區別又(you)分(fen)為(wei)六個分(fen)支(zhi)小類(直動膜片結(jie)(jie)(jie)構(gou)、分(fen)步(bu)重片結(jie)(jie)(jie)構(gou)、先(xian)導膜式結(jie)(jie)(jie)構(gou)、直動活塞(sai)結(jie)(jie)(jie)構(gou)、分(fen)步(bu)直動活塞(sai)結(jie)(jie)(jie)構(gou)、先(xian)導活塞(sai)結(jie)(jie)(jie)構(gou))。
