低價銷售美國VICKERS威格士葉片泵 美國VICKERS威格士葉片泵是一種高壓力,高轉(zhuǎn)速,雙作用平衡式葉片泵,葉片采用*結(jié)構(gòu),減少了葉片與定子之間的接觸能力,轉(zhuǎn)子的設(shè)計使轉(zhuǎn)子根部有足夠的強度,轉(zhuǎn)子兩邊的設(shè)置配流側(cè)板,通過側(cè)板的壓力補償作用,使泵的動態(tài)良好,隨著壓力的升高,自動減少了泄漏間隙,使泵保持高容積效率;威格士柱塞結(jié)構(gòu)各處都采用了消聲結(jié)構(gòu),實現(xiàn)了低噪音,穩(wěn)定性強。 美國威格士VICKERS葉片泵的工作原理單作用:葉片是鑲嵌在槽里的,可以自由滑動,當(dāng)旋轉(zhuǎn)產(chǎn)生時,葉片在離心作用下甩到泵殼上,葉片泵是容積泵,相鄰的兩個葉片運動到下邊時與泵殼和轉(zhuǎn)子封閉的容積zui小,在上邊 時zui大, 當(dāng)轉(zhuǎn)子順時針轉(zhuǎn)動時, 相鄰兩葉片經(jīng)歷從zui下邊到zui上邊的過程就是容積增大過程, 所以吸油(從第四象限到第二象限); 從zui上到zui下是容積減小過程, 所以壓油(從第二到第四 象限). 雙作用: 當(dāng)電機帶動轉(zhuǎn)子沿轉(zhuǎn)動時, 葉片在離心力和葉片底部壓力油的雙重作用下向外伸出,其頂部緊貼在定子內(nèi)表面上.處于四段同心圓弧上的四個葉片分別與轉(zhuǎn)子外表面,定 子內(nèi)表面及兩個配流盤組成四個密封工作油腔. 這些油腔隨著轉(zhuǎn)子的轉(zhuǎn)動, 密封工作油腔產(chǎn) 生由小到大或由大到小的變化, 可以通過配流盤的吸油窗口(與吸油口相連)或排油窗口(與排 油口相連)將油液吸入或壓出. 美國威格士VICKERS葉片泵是轉(zhuǎn)子槽內(nèi)的葉片與泵殼(定子環(huán))相接觸,將吸入的液體由進(jìn)油側(cè)壓向排油側(cè)的泵。VICKERS葉片泵的工作原理定子內(nèi)腔型線是圓,轉(zhuǎn)子軸與定子偏心。逆時針回轉(zhuǎn)時,工作V右半轉(zhuǎn)增大,左半轉(zhuǎn)V 減小。從兩側(cè)配油盤的吸、排口吸排油。兩相鄰葉片轉(zhuǎn)到吸、排油口間的密封區(qū)時,所接觸定子曲線不是與轉(zhuǎn)子同心的圓弧。密封區(qū)的圓心角略大于相鄰葉片所占圓心角。 通過在排出口邊緣開三角形卸荷槽的方法即可解決。定子、轉(zhuǎn)子和軸承受徑向力作用,屬非卸荷式葉片泵。工作P不宜太高,Q的均勻性也比雙作用差。移動定子可改變偏心的方向及大小,可做成n恒定而Q可變的雙向或單向的無級變量泵。其中用得較多的是限壓式變量葉片泵。 威格士葉片泵的結(jié)構(gòu)定子和左、右配油盤裝在泵體中,用圓柱銷定位,右配油盤背后的槽e通排油腔,轉(zhuǎn)子通過花鍵帶動,傳動軸由滾針軸承和球軸承支承。下面介紹雙作用葉片泵結(jié)構(gòu)的主要部分:定子過渡曲線必須設(shè)計成使葉片在葉槽中移動速度的變化盡可能小,以免產(chǎn)生太大的慣性力,導(dǎo)致葉片與定子的脫離或沖擊。為使葉片在吸入?yún)^(qū)能貼緊定子,雙作用葉片泵一般使葉片底部與排出油腔相通,配油盤端面環(huán)槽C有小孔與排出腔相通 單作用葉片泵由于葉片在轉(zhuǎn)過吸入?yún)^(qū)時向外伸出的加速度較小,單靠離心力即足以保證葉片貼緊定子。雙作用泵的葉片數(shù)Z應(yīng)取偶數(shù),保證轉(zhuǎn)子徑向力平衡。
VICKERS威格士葉片泵具有流量均勻,運轉(zhuǎn)平穩(wěn),噪聲小,體積小,重量輕等優(yōu)點。在機床、工程機械、船舶、壓鑄及冶金設(shè)備中得到廣泛應(yīng)用。中低壓葉片泵的工作壓力一般為8MPa,中高壓葉片泵的工作壓力可達(dá)25MPa至32MPa。葉片泵主要分為單作用(轉(zhuǎn)子每轉(zhuǎn)一周完成吸、排油各一次)和雙作用(轉(zhuǎn)子每轉(zhuǎn)一周完成吸、排油各二次)兩種形式。雙作用葉片泵與單作用葉片泵相比,其流量均勻性好,轉(zhuǎn)子體所受的徑向液壓力基本平衡。雙作用葉片泵都做成定量泵型式,單作用泵一般設(shè)計成可以無級調(diào)節(jié)排量的變量泵。 低價銷售美國VICKERS威格士葉片泵 公司主要做歐美品牌,我們在德國有公司,可以采購歐洲任何國家的品牌,比如德國的優(yōu)勢品牌有:FESTO費斯托,BURKERT寶德,BOSCH-REXROTH博世力士樂,IFM易福門,TURCK圖爾克,P+F倍加福,BALLUFF巴魯夫,SICK施克,HIRSCHMAN赫斯曼,MURR穆爾,HYDAC賀德克,GSR,CROUZET高諾斯,E+H恩格斯豪斯,PILZ皮爾茲,HAWE哈威,SIEMENS西門子,STAUFF西德福,EUCHNER安士能,EMG伺服閥,UNIVER,ATOS阿托斯,NORGREN諾冠等歐洲國家大概有500個大小品牌跟我司有合作關(guān)系。 我們在美國也有公司,比如美國的ASCO阿斯卡,VICKERS威格士,MAC,PARKER派克,MOOG穆格,F(xiàn)AIRCHILD仙童,DENISON丹尼遜,ROSS,UE,MTS,GEFRAN杰夫倫,KACON凱昆等,大概200多個品牌有合作。 日本品牌我們有代理權(quán),比如日本的CKD喜開理,KEYENCE基恩士,SUNX神視,TOYOOKI豐興,NACHI不二越,DAIKIN大金,SMC,KOGANEI小金井,TACO,NOK,TOKIMEC東機美,YASKAWA安川,YAMATAKE山武,東方馬達(dá)等品牌。 PVH074R01AA10B25200000100100010A PVH74C-RF-1S-10-C25V-31 PVH074R01AA10A250000001001AA010A PVH74C-RF-1S-11-C25-31 PVH074R01AA10B252000001001AA010A PVH74C-RF-1S-11-C25V-31 PVH074R02AA10A25000000100100010A PVH74C-RF-2S-10-C25-31 PVH074R02AA10B25200000100100010A PVH74C-RF-2S-10-C25V-31 PVH074R02AA10B252000001001AA010A PVH74C-RF-2S-11-C25V-31 PVH074R01AA10A25000000200100010A PVH74C-RSF-1S-10-C25-31 PVH074R01AA10B25200000200100010A PVH74C-RSF-1S-10-C25V-31 PVH074R01AA10A250000002001AA010A PVH74C-RSF-1S-11-C25-31 PVH074R02AA10A25000000200100010A PVH74C-RSF-2S-10-C25-31 PVH074R02AA10B25200000200100010A PVH74C-RSF-2S-10-C25V-31 PVH074R01AA10A250000001001AB010A PVH74QIC-RF-1S-10-C25-31 PVH074R01AA10B252000001001AB010A PVH74QIC-RF-1S-10-C25V-31 PVH074R01AA10A250000001001AE010A PVH74QIC-RF-1S-11-C25-31 PVH074R01AA10B252000001001AE010A PVH74QIC-RF-1S-11-C25V-31 PVH074R02AA10A250000001001AB010A PVH74QIC-RF-2S-10-C25-31 PVH074R02AA10B252000001001AB010A PVH74QIC-RF-2S-10-C25V-31 PVH074R02AA10A250000001001AE010A PVH74QIC-RF-2S-11-C25-31 PVH074R02AA10B252000001001AE010A PVH74QIC-RF-2S-11-C25V-31 PVH074R01AB10A250000001001AB010A PVH74QIC-RM-1S-10-C25-31 PVH074R02AB10A250000001001AE010A PVH74QIC-RM-2S-11-C25-31 PVH074R01AA10A250000002001AB010A PVH74QIC-RSF-1S-10-C25-31 PVH074R01AA10B252000002001AB010A PVH74QIC-RSF-1S-10-C25V-31 PVH074R01AA10A250000002001AE010A PVH74QIC-RSF-1S-11-C25-31 PVH074R02AA10A250000002001AB010A PVH74QIC-RSF-2S-10-C25-31 PVH074R02AA10A250000002001AE010A PVH74QIC-RSF-2S-11-C25-31 PVH074R01AB10A250000002001AE010A PVH74QIC-RSM-1S-11-C25-31 PVH098R01AJ30B25200000100100010A PVH98C-RF-1S-10-C25V-31 PVH098R01AJ30B252000001001AA010A PVH98C-RF-1S-11-C25V-31 PVH098R02AJ30A25000000100100010A PVH98C-RF-2S-10-C25-31 PVH098R02AJ30B25200000100100010A PVH98C-RF-2S-10-C25V-31 PVH098R02AJ30B252000001001AA010A PVH98C-RF-2S-11-C25V-31 PVH098R01AJ30A25000000200100010A PVH98C-RSF-1S-10-C25-31 PVH098R01AJ30B25200000200100010A PVH98C-RSF-1S-10-C25V-31 PVH098R02AJ30A25000000200100010A PVH98C-RSF-2S-10-C25-31 PVH098R02AJ30B25200000200100010A PVH98C-RSF-2S-10-C25V-31 PVH098R01AJ30A250000001001AB010A PVH98QIC-RF-1S-10-C25-31 PVH098R01AJ30B252000001001AB010A PVH98QIC-RF-1S-10-C25V-31 PVH098R01AJ30A250000001001AE010A PVH98QIC-RF-1S-11-C25-31 PVH098R02AJ30B252000001001AB010A PVH98QIC-RF-2S-10-C25V-31 PVH098R02AJ30A250000001001AE010A PVH98QIC-RF-2S-11-C25-31 PVH098R01AD30A250000001001AB010A PVH98QIC-RM-1S-10-C25-31 PVH098R01AD30A250000001001AE010A PVH98QIC-RM-1S-11-C25-31 PVH098R01AJ30A250000002001AB010A PVH98QIC-RSF-1S-10-C25-31 PVH098R01AJ30B252000002001AB010A PVH98QIC-RSF-1S-10-C25V-31 PVH098R01AJ30A250000002001AE010A PVH98QIC-RSF-1S-11-C25-31 PVH098R02AJ30A250000002001AB010A PVH98QIC-RSF-2S-10-C25-31 PVH098R02AJ30A250000002001AE010A PVH98QIC-RSF-2S-11-C25-31 PVH098R01AD30A250000002001AB010A PVH98QIC-RSM-1S-10-C25-31
