葉輪中的液體繞流葉片,REXROTH葉片泵在繞流運(yùn)動(dòng)中液體作用一升力于葉片,反過來葉片以一個(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。 葉輪進(jìn)口處因液體的排出而形成真空或低壓,力士樂葉片泵的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。 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。 REXROTH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。 上海維特銳與德國(guó)REXROTH合作多年,上海維特銳在德國(guó)設(shè)立的公司可以持續(xù)穩(wěn)定供應(yīng)力士樂產(chǎn)品 R900771631 PV7-1X/100-118RE07MD0-16-A427 R900770527 ABHPG-PV7/10-14C0/112M-4-B0/J R900768658 PV7-1X/25-30RE01MW0-16 R900763234 ABKAG-60AL9/PV7-10/90L-4-A1/NL/012B605A1 R900761807 PV7-1X/100-150RE07MC5-08WG R900758432 PV7-2X/20-20RE01MA3-10 R900755261 PV7-2X/20-20RA01MA3-05 R900751356 PV7-1X/25-45RE01MC7-08WG R900750169 PV7-1X/63-71RE07MD6-16 R900749846 PV7-2X/20-20RA01MA3-10 R900744715 PV7-1X/63-71RE07MN0-16 R900744495 PV7-1X/25-30RE01MW0-16WH R900741427 PV7-2X/20-25RA01MA3-05 R900740824 PV7-1X/100-118RE07MW0-16WH R900738663 PV7-1X/10-20RE01MC5-10WG R900733271 PV7-1X/63-71RE07MW0-16 R900729468 PV7-1X/10-14RE01KD0-16 R900720730 PV7-1X/63-71RE07MC0-16-A234 R900720285 ABAPG-PV7/63-71C0-16/200L-4-B0K/SE-A R900718547 ABHPG-PV7/20-25-0-10/112M-4-B0/S-A R900711250 PV7-1X/40-71RE37MC5-08WH R900707375 PV7-2X/20-25RE01MA0-10 R900707373 PV7-2X/20-20RE01MA0-10 R900707372 PV7-2X/20-20RE01MA0-05 R900705106 PV7-1X/63-71RE07MC7-16WH R900704549 PV7-2X/20-25RA01MA3-10 R900919237 PV7-1X/06-14RA01MA0-07 R900910016 PV7-1X/40-45RE37MC5-16WG R900247239 PV7-1X/10-20RE01MC5-10WH R900245924 PV7-1X/16-30RE01MC5-08WH |
