經(jīng)營(yíng)產(chǎn)品:葉片泵的管理要點(diǎn)除需防干轉(zhuǎn)和過(guò)載、防吸入空氣和吸入真空度過(guò)大外,還應(yīng)注意:
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(pán)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(zhuān)門(mén)設(shè)計(jì)。
2.葉片泵裝配 配油盤(pán)與定子用定位銷(xiāo)正確定位,葉片、轉(zhuǎn)子、配油盤(pán)都不得裝反,定子內(nèi)表面吸入?yún)^(qū)部分最易磨損,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(guò)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(guò)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(pán)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(pán)、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?lè)较蛐D(zhuǎn)時(shí),圖右側(cè)的葉片向外伸出,密封工作腔容積逐漸增大,產(chǎn)生真空,于是通過(guò)吸油口6和配油盤(pán)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(pán)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(guò)程中,吸油壓油各一次,故稱(chēng)單作用泵。轉(zhuǎn)子受到徑向液壓不平衡作用力,故又稱(chēng)非平衡式泵,其軸承負(fù)載較大。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(guò)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?lè)较蛐D(zhuǎn)的情況下,密封工作腔的容積在左上角和右下角處逐漸增大,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(kāi)。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(chēng)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(chēng)的,作用在轉(zhuǎn)子上的液壓力徑向平衡,所以又稱(chēng)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。
