Vickers葉片泵的工作原理
Vickers葉片泵轉(zhuǎn)子旋轉(zhuǎn)時(shí),葉片在離心力和壓力油的作用下,尖部緊貼在定子內(nèi)表面上。這樣兩個(gè)葉片與轉(zhuǎn)子和定子內(nèi)表面所構(gòu)成的工作容積,先由小到大吸油后再由大到小排油,葉片旋轉(zhuǎn)一周時(shí),完成兩次吸油與排油。
一、單作用Vickers葉片泵的工作原理
泵由轉(zhuǎn)子2、定子3、葉片4、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?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(guò)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Vickers葉片泵的工作原理
它的作用原理和單作用Vickers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。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Vickers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Vickers葉片泵。
雙作用Vickers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Vickers葉片泵的葉片數(shù)一般都取12或16。
容積泵中的滑片泵的注意事項(xiàng)
Vickers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Vickers葉片泵都有規(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)。可逆轉(zhuǎn)的Vickers葉片泵必須專門設(shè)計(jì)。
2.Vickers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zui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.Vickers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。
作為泵產(chǎn)品,Vickers葉片泵更多地指滑片泵。只要你有興趣在 搜索發(fā)現(xiàn),Vickers葉片泵幾乎全部指滑片泵。

頂蓋處螺絲松動(dòng),軸向間隙增大,容積效率下降適當(dāng)擰緊螺釘,保證間隙均勻、適當(dāng)(間隙為0.04~0.07mm)
個(gè)別葉片滑動(dòng)不靈活清洗。清洗后仍不靈活時(shí),應(yīng)單槽調(diào)配,使葉片在自重狀態(tài)下能慢慢地自動(dòng)下落為宜(間隙為0.015~0.025mm)
定子內(nèi)表面磨損,葉片不能與定子內(nèi)表面良好接觸定子內(nèi)表面磨損一般在吸油腔處,對(duì)于已預(yù)加工銷孔的定子可翻轉(zhuǎn)180°使用,否則更換新零件

1、自行設(shè)計(jì)的定量泵轉(zhuǎn)子,可提供客戶規(guī)定范圍之供液能力。
2、*的正壓式結(jié)構(gòu),使熔液流動(dòng)速度更加穩(wěn)定。
3、根據(jù)客戶要求定做,可與各品牌型號(hào)之壓鑄設(shè)備配合。
相關(guān)區(qū)別
在轉(zhuǎn)速恒定的條件下,輸出流量可變的為變量泵,反之為定量泵。他們zui大的不同就是變量泵的軸是便心安裝。簡(jiǎn)單來(lái)說(shuō)定量泵的轉(zhuǎn)速選定后,他的流量和壓力就確定了,就不能調(diào)節(jié)。變量泵的輸出流量可以根據(jù)系統(tǒng)的壓力變化(外負(fù)載的大?。?,自動(dòng)地調(diào)節(jié)流量,就是壓力高時(shí)輸出流量小,壓力低時(shí)輸出流量大,這樣他可以節(jié)省液壓元件的數(shù)量,從而簡(jiǎn)化了油路系統(tǒng),而且可以減少油發(fā)熱。缺點(diǎn)是流量脈動(dòng)嚴(yán)重,系統(tǒng)壓力不太平穩(wěn),泵的壽命短,泵的軸承容易壞,因?yàn)樗瞧陌惭b,而且泵的嘈音大。
Vickers葉片泵通過(guò)調(diào)節(jié)偏心距、柱塞泵通過(guò)調(diào)節(jié)滑板角度可以實(shí)現(xiàn)變量。
差動(dòng)定量泵
涉及定量泵技術(shù)領(lǐng)域,特別是一種差動(dòng)定量泵,包括PLC控制裝置,壓力流體管路及其控制裝置,由一個(gè)泵體,泵體給料側(cè)的給料側(cè)端蓋,泵體排給料側(cè)的排料側(cè)端蓋,泵體內(nèi)的與此給料側(cè)端蓋相連接的主動(dòng)活塞,頂靠在此主動(dòng)活塞上的差動(dòng)套,與此主動(dòng)活塞相連接的給料口和出料口,連接所述的給料側(cè)端蓋和排料側(cè)端蓋的側(cè)向連接桿所組成。主動(dòng)活塞設(shè)有兩個(gè)密封環(huán)。差動(dòng)套內(nèi)外各有兩個(gè)密封環(huán)。側(cè)向連接桿穿過(guò)所述的差動(dòng)套并通過(guò)螺栓與所述的主動(dòng)活塞相連接。給料側(cè)端蓋和排料側(cè)端蓋通過(guò)螺栓與所述的泵體相連接。主動(dòng)活塞通過(guò)管路與控制裝置的電磁氣動(dòng)閥相連接,電磁氣動(dòng)閥與PLC控制裝置相連接。提供了一種零部件少、機(jī)構(gòu)簡(jiǎn)單、故障率低、維修方便、成本較低的定量泵。
隔膜式定量泵工作原理及常見(jiàn)故障排除方法
(1)利用隔膜之前后動(dòng)作使隔膜與泵頭間變化造成球閥上下移動(dòng)形成真空吸附與推擠現(xiàn)象達(dá)到液體輸送之目的。
①當(dāng)膜片往后拉時(shí),出口球閥掉下與球座緊緊密合,入口球閥因膜片后拉時(shí)與泵頭間產(chǎn)生真空而往上浮起,液體跟著被吸上來(lái)。
②當(dāng)膜片往前推時(shí),入口球閥與球座氣密,使液體不會(huì)通過(guò),而出口因膜片往前推擠使球閥開啟,液體吐出
(2)由以上之動(dòng)作原理我們可簡(jiǎn)單地知道膜片、泵頭、球閥球座任何一項(xiàng)因素造成漏氣則無(wú)法達(dá)到輸送之目的,或流量異常,通常由此四項(xiàng)組成主生之故障為:
①球座與球閥無(wú)法氣密
②入口、出口異物阻塞
③膜片破損
故若液體輸送異常,朝這方面處理,應(yīng)該都可解決,而造成上述情況之因素為何,不勝枚舉,端視當(dāng)時(shí)之配管、配件及操作情形才可判定。
