REXROTH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)，完成一次吸油與排油。 德國(guó)REXROTH力士樂(lè)葉片泵工作前，先將泵內(nèi)充滿液體，然后啟動(dòng)離心泵，葉輪快速轉(zhuǎn)動(dòng)，葉輪的葉片驅(qū)使液體轉(zhuǎn)動(dòng)，液體轉(zhuǎn)動(dòng)時(shí)依靠慣性向葉輪外緣流去，同時(shí)葉輪從吸入室吸進(jìn)液體，在這一過(guò)程中，力士樂(lè)葉片泵葉輪中的液體繞流葉片，在繞流運(yùn)動(dòng)中液體作用一升力于葉片，反過(guò)來(lái)葉片以一個(gè)與此升力大小相等、方向相反的力作用于液體，這個(gè)力對(duì)液體做功，使液體得到能量而流出葉輪，這時(shí)液體 的動(dòng)能與壓能均增大。 REXROTH葉片泵依靠旋轉(zhuǎn)葉輪對(duì)液體的作用把原動(dòng)機(jī)的機(jī)械能傳遞給液體。由于離心泵的作用液體從葉輪進(jìn)口流向出口的過(guò)程中，其速度能和壓力能都得到增加，被葉輪排出的液體經(jīng)過(guò)壓出室，大部分速度能轉(zhuǎn)換成壓力能，然后沿排出管路輸送出去 這時(shí)，REXROTH葉片泵葉輪進(jìn)口處因液體的排出而形成真空或低壓，吸水池中的液體在液面壓力(大氣壓)的作用下，被壓入葉輪的進(jìn)口，于是，旋轉(zhuǎn)著的葉輪就連續(xù)不斷地吸入和排出液體。 上海維特銳專(zhuān)業(yè)報(bào)價(jià)德國(guó)REXROTH R900546887 PV7-1X/63-71RE07KC3-16 R900546886 PV7-1X/25-30RE01KC3-16 R900539886 PV7-1X/40-71RE37MD0-08 R900538525 PV7-1X/25-45RE01MC3-08 R900538125 PV7-1X/10-20RE01MC3-10 R900537419 PV7-1X/10-14RE01MN0-16 R900534508 PV7-1X/25-45RE01MC0-08 R900534412 PV7-1X/16-20RE01MC7-16 R900534143 PV7-1X/10-20RE01MC0-10 R900533851 PV7-1X/10-14RE01MC0-16-A184 R900533637 PV7-1X/100-118RE07MC7-16 R900533582 PV7-1X/16-30RE01MC0-08 R900533296 PV7-1X/16-30RE01MC3-08 R900532770 PV7-1X/100-118RE07MD0-16 R900535588 PV7-1X/40-71RE37MC0-08 R900535532 PV7-1X/25-45RE01MC5-08 R900523597 PV7-1X/40-45RE37KC0-16 R900520787 PV7-1X/10-14RE01MD5-16 R900520401 PV7-1X/10-14RE01MC5-16 R900519094 PV7-1X/63-71RE07MD0-16 R900518218 PV7-1X/63-71RE07MC5-16 R900517795 PV7-1X/16-20RE01MC0-16-A184 R900517464 PV7-1X/25-30RE01MC5-16 R900516546 PV7-1X/100-118RE07MC5-16 R900511986 PV7-1X/63-71RE07MC3-16 R900511215 PV7-1X/100-118RE07MC3-16 R900509506 PV7-1X/25-30RE01MD0-16 R900509274 PV7-1X/16-20RE01MD0-16 R900509053 PV7-1X/10-14RE01MC7-16 R900506809 PV7-1X/100-118RE07MC0-16 R900506808 PV7-1X/63-71RE07MC0-16 R900506473 PV7-1X/16-20RE01MC5-16 R900504653 PV7-1X/10-14RE01MD0-16 R900502277 PV7-1X/40-45RE37MC5-16 R901134661 PV7-1X/16-20RE01MD6-16 R901133981 PV7-1X/63-71RE07MC3-06-A460 R901129340 PV7-1X/100-118RE07MW6-16WH R901100271 ABAPG-PV7/40-45C0+06-10A0/160L-4-B1/SE R901083391 ABHPG-PV7/16-20C0+PF-005/132M-4-B1/LF R901083371 ABAPG-PV7/63-71C5WH+GH2-008/200L-4-N0/E& R901081778 PV7-1X/06-14RA01MA0-10-A452 R901072539 ABPBG-PV7/100-118C0+GF3-40+GF2-08/BG160* R901065655 PV7-1X/06-10RA01KA0-05 R901064326 PV7-1X/40-55RE37MC0-08-A449 R901062106 ABHPG-PV7/40-45C0/132S-4-B0/S * R901062065 ABHPG-PV7/06-10A0/100L-4-A1K/L VEM R901061279 PV7-1X/100-118RE07MW0-16WG R901059512 PV7-1X/40-71RE37MW0-08WH R901055473 PV7-1X/40-45RE37MW0-16WG R901054762 ABHPG-PV7/10-20C0+10-20C0/100L-4-A0/S R901054761 ABHPG-PV7/06-10A0/90S-4-A0/S R901049367 ABHAG-0160S43/PV7-25/132M/NTW/005C068A R901049299 ABAPG-PV7-118D0+10SO18DRG/225S-4-B0/SEFR R901047776 PV7-1X/40-45RE37MC0-16-A446 R901047606 PV7-1X/06-10RA01KA0-10 R901043560 PV7-1X/10-20RE01MW0-10WH R901041243 ABHAG-0160SS0/PV7-25/160M/AB1A041A |
