廣泛應(yīng)用于鋼鐵、冶金、鋁行業(yè)、石油化工、航天、船舶制造、煤炭、水泥、電力、汽車、工程機(jī)械、食品、藥業(yè)、林業(yè)、紡織、皮革、造紙等行業(yè)領(lǐng)域

 

電磁閥是用電磁的效應(yīng)進(jìn)行控制,主要的控制方式由繼電器控制。這樣,電磁閥可以配合不同的電路來實(shí)現(xiàn)預(yù)期的控制,而控制的精度和靈活性都能夠保證。
電磁閥的主要特點(diǎn)
(1)外漏堵絕,內(nèi)漏易控,使用安全。內(nèi)外泄漏是危及安全的要素。其它自控閥通常將閥桿伸出,由電動(dòng)、氣動(dòng)、液動(dòng)執(zhí)行機(jī)構(gòu)控制閥芯的轉(zhuǎn)動(dòng)或移動(dòng)。這都要解決長(zhǎng)期動(dòng)作閥桿動(dòng)密封的外泄漏難題;唯有電磁閥是用電磁力作用于密封在隔磁套管內(nèi)的鐵芯完成,不存在動(dòng)密封,所以外漏易堵絕。電動(dòng)閥力矩控制不易,容易產(chǎn)生內(nèi)漏,甚至拉斷閥桿頭部;電磁閥的結(jié)構(gòu)型式容易控制內(nèi)泄漏,直至降為零。所以,電磁閥使用特別安全,尤其適用于腐蝕性、有毒或高低溫的介質(zhì)。
(2)系統(tǒng)簡(jiǎn)單,便接電腦,價(jià)格低謙。電磁閥本身結(jié)構(gòu)簡(jiǎn)單,價(jià)格也低,比起調(diào)節(jié)閥等其它種類執(zhí)行器易于安裝維護(hù)。更顯著的是所組成的自控系統(tǒng)簡(jiǎn)單得多,價(jià)格要低得多。由于電磁閥是開關(guān)信號(hào)控制,與工控計(jì)算機(jī)連接十分方便。在當(dāng)今電腦普及,價(jià)格大幅下降的時(shí)代,電磁閥的優(yōu)勢(shì)就更加明顯。
(3)動(dòng)作快遞,功率微小,外形輕巧。電磁閥響應(yīng)時(shí)間可以短至幾個(gè)毫秒,即使是先導(dǎo)式電磁閥也可以控制在幾十毫秒內(nèi)。由于自成回路,比之其它自控閥反應(yīng)更靈敏。設(shè)計(jì)得當(dāng)?shù)碾姶砰y線圈功率消耗很低,屬節(jié)能產(chǎn)品;還可做到只需觸發(fā)動(dòng)作,自動(dòng)保持閥位,平時(shí)一點(diǎn)也不耗電。電磁閥外形尺寸小,既節(jié)省空間,又輕巧美觀。
(4)調(diào)節(jié)精度受限,適用介質(zhì)受限。電磁閥通常只有開關(guān)兩種狀態(tài),閥芯只能處于兩個(gè)較限位置,不能連續(xù)調(diào)節(jié),(力圖打破的新構(gòu)思不少,但還都處于試驗(yàn)試用階段)所以調(diào)節(jié)精度還受到一定限制。電磁閥對(duì)介質(zhì)潔凈度有較高要求,含顆粒狀的介質(zhì)不能適用,如屬雜質(zhì)須先濾去。另外,粘稠狀介質(zhì)不能適用,而且,特定的產(chǎn)品適用的介質(zhì)粘度范圍相對(duì)較窄。
(5)型號(hào)多樣,用途廣泛。電磁閥雖有先天不足,優(yōu)點(diǎn)仍十分突出,所以就設(shè)計(jì)成多種多樣的產(chǎn)品,滿足各種不同的需求,用途較為廣泛。電磁閥技術(shù)的進(jìn)步也都是圍繞著如何克服先天不足,如何更好地發(fā)揮固有優(yōu)勢(shì)而展開。0810050134 H-4WEH16U1X/6ZG24N9ETK4/B08Z

R900906426 H-4WEH 22 J7X/6EG24N9K4液壓閥是用來控制液壓系統(tǒng)中油液的流動(dòng)方向或調(diào)節(jié)其壓力和流量的,因此它可分為方向閥、壓力閥和流量閥三大類。一個(gè)形狀相同的閥,可以因?yàn)樽饔脵C(jī)制的不同,而具有不同的功能。壓力閥和流量閥利用通流截面的節(jié)流作用控制著系統(tǒng)的壓力和流量,而方向閥則利用通流通道的更換控制著油液的流動(dòng)方向。這就是說,盡管液壓閥存在著各種各樣不同的類型,它們之間還是保持著一些基本共同之點(diǎn)的。例如:
(1)在結(jié)構(gòu)上,所有的閥都有閥體、閥芯(轉(zhuǎn)閥或滑閥)和驅(qū)使閥芯動(dòng)作的元、部件(如彈簧、電磁鐵)組成
(2)在工作原理上,所有閥的開口大小,閥進(jìn)、出口間壓差以及流過閥的流量之間的關(guān)系都符合孔口流量公式,僅是各種閥控制的參數(shù)各不相同而已。

1.泵轉(zhuǎn)向改變,則其吸排方向也改變?nèi)~片泵都有規(guī)定的轉(zhuǎn)向,不允許反。因?yàn)檗D(zhuǎn)子葉槽有傾斜,葉片有倒角,葉片底部與排油腔通,配油盤上的節(jié)流槽和吸、排口是按既定轉(zhuǎn)向設(shè)計(jì)?赡孓D(zhuǎn)的葉片泵必須專門設(shè)計(jì)。
2.葉片泵裝配 配油盤與定子用定位銷正確定位,葉片、轉(zhuǎn)子、配油盤都不得裝反,定子內(nèi)表面吸入?yún)^(qū)部分較易磨損,必要時(shí)可將其翻轉(zhuǎn)安裝,以使原吸入?yún)^(qū)變?yōu)榕懦鰠^(qū)而繼續(xù)使用。
3.拆裝 注意工作表面清潔,工作時(shí)油液應(yīng)很好過濾。
4. 葉片在葉槽中的間隙太大會(huì)使漏泄增加,太小則葉片不能自由伸縮,會(huì)導(dǎo)致工作失常。
5.葉片泵的軸向間隙 對(duì)ηv影響很大。
1)小型泵-0.015~0.03mm
2)中型泵-0.02~0.045mm
6.油液的溫度和粘度 一般不宜超過55℃,粘度要求在17~37mm2/s之間。粘度太大則吸油困難;粘度太小則漏泄嚴(yán)重。


一、單作用葉片泵的工作原理
泵由轉(zhuǎn)子1、定子2、葉片3、配油盤和端蓋等部件所組成。定子的內(nèi)表面是圓柱形孔。轉(zhuǎn)子和定子之間存在著偏心。葉片在轉(zhuǎn)子的槽內(nèi)可靈活滑動(dòng),在轉(zhuǎn)子轉(zhuǎn)動(dòng)時(shí)的離心力以及通入葉片根部壓力油的作用下,葉片頂部貼緊在定子內(nèi)表面上,于是兩相鄰葉片、配油盤、定子和轉(zhuǎn)子間便形成了一個(gè)個(gè)密封的工作腔。當(dāng)轉(zhuǎn)子按逆時(shí)針方向旋轉(zhuǎn)時(shí),圖右側(cè)的葉片向外伸出,密封工作腔容積逐漸加大,產(chǎn)生真空,于是通過吸油口6和配油盤5上窗口將油吸入。而在圖的左側(cè)。葉片往里縮進(jìn),密封腔的容積逐漸縮小,密封腔中的油液經(jīng)配油盤另一窗口和壓油口1被壓出而輸出到系統(tǒng)中去。這種泵在轉(zhuǎn)子轉(zhuǎn)一轉(zhuǎn)過程中,吸油壓油各一次,故稱單作用泵。轉(zhuǎn)子受到徑向液壓不平衡作用力,故又稱非平衡式泵,其軸承負(fù)載非常大。改變定子和轉(zhuǎn)子間的偏心量,便可改變泵的排量,故這種泵都是變量泵。
二、雙作用葉片泵的工作原理
它的作用原理和單作用葉片泵相似,不同之處只在于定子表面是由兩段長(zhǎng)半徑圓弧、兩段短半徑圓弧和四段過渡曲線八個(gè)部分組成,且定子和轉(zhuǎn)子是同心的。在圖示轉(zhuǎn)子順時(shí)針方向旋轉(zhuǎn)的情況下,密封工作腔的容積在左上角和右下角處逐漸加大,為吸油區(qū),在左下角和右上角處逐漸減小,為壓油區(qū);吸油區(qū)和壓油區(qū)之間有一段封油區(qū)把它們隔開。這種泵的轉(zhuǎn)子每轉(zhuǎn)一轉(zhuǎn),每個(gè)密封工作腔完成吸油和壓油動(dòng)作各兩次,所以稱為雙作用葉片泵。泵的兩個(gè)吸油區(qū)和兩個(gè)壓油區(qū)是徑向?qū)ΨQ的,作用在轉(zhuǎn)子上的液壓力徑向平衡,所以又稱為平衡式葉片泵。
雙作用葉片泵的瞬時(shí)流量是脈動(dòng)的,當(dāng)葉片數(shù)為4的倍數(shù)時(shí)脈動(dòng)率小。為此,雙作用葉片泵的葉片數(shù)一般都取12或16。我們主營(yíng)的產(chǎn)品:原裝德國(guó)BOSCH REXROTH(博世-力士樂)液壓閥,柱塞泵,馬達(dá). Rexroth力士樂
