現(xiàn)貨供應(yīng)力士樂REXROTH定量泵 REXROTH定量泵區(qū)分為開回路及閉回路兩種類型,兩者主要差別在于閉回路變量泵的機(jī)臺穩(wěn)定性較佳,然而成本卻也高出一倍,早期中國臺灣廠商所使用的變量泵多為閉回路類型。而目前部分大陸塑機(jī)廠家為了節(jié)省成本,采用開回路變量泵,其價格相差一倍,導(dǎo)致許多廠家以為物美價廉,撿到便宜,殊不知“一分錢,一分貨”,變量泵仍是有等級優(yōu)劣之分的,其節(jié)能效果及機(jī)臺穩(wěn)定性更是有很大差別。因此,在選用變量節(jié)能機(jī)時應(yīng)特別注意所配置的變量泵類型究竟是開回路還是閉回路,因為其對于機(jī)臺穩(wěn)定性有性的影響。此外,對于一般普通產(chǎn)品而言,花同樣的成本加裝開回路變量泵來節(jié)能,還是加裝半閉回路來提升機(jī)臺的穩(wěn)定性及重現(xiàn)性,是值得廠家仔細(xì)權(quán)衡的問題。 現(xiàn)貨供應(yīng)力士樂REXROTH定量泵 A10V0100DR/31R-PSC11N00 A10V028DR A10V028DR/31R-PSC62K01-S1581 A10VO28DFR1/31L-PSC62N00 A10VO28DFR1/31R-PSC62N00 A10VO28DR/31R-PSC12N00 a10vo45dfr1/31r-psc62k02 a10vs0100dfr1/31r-ppa12n00 A10VS0100DFR1/32R-VPB12N00 a10vs0100dr/31r-ppa12n00 A10VS0100DR/31R-PTA12N00 A10VS0100DR/31R-VPA12N00 A10VS0140DFR1/31R-PPB12N00 a10vs0140dr/31r-ppb12n00 a10vs018dfr1/31r-ppb12n00 A10VS018DFR1/31R-PPB12N00 A10VS018DFR1/31R-PPB12NOO a10vs018dr/31r-ppa12n00 a10vs028dfr1/31r-ppa12n00 A10VS028DR/31R-PPA12N00 a10vs045dfr1/31r-ppa12n00 A10VS045DFR1/31R-PSA12N00 a10vs045dr/31r-ppa12n00 a10vs071dfr1/31r-ppa12n00 A10VSO100 A10VSO100DFLR/31R-PPA12N00 A10VSO100DFR/31R-PPA12N00 A10VSO100DFR1/31R-PPA12KB4 a10vso100dfr1/31r-ppa12n00 A10VSO100DFR1/32R-PPB12 a10vso100dfr1/32r-ppb12n00 A10VSO100DFR1/32R-VPB12N00 A10VSO100DFR1/32R-VPB12N00S/439 a10vso100dr/31r-ppa12n00 A10VSO100DR/31R-PPB12N00 a10vso100dr/31r-vpa12n00 A10VSO10DR/52RPPA14N00 A10VSO140 A10VSO140 DFR1/31R-PPB12N00 A10VSO140D/31R-PPB12N00 A10VSO140DFLR/31R-PPB12N00 A10VSO140-DFR/31R-PPA12-N00 a10vso140dfr1/31r-ppa12n00 A10VSO140DFR1/31R-PPB12N00 A10VSO140DFR1S/31R-PPB12N00 A10VSO140DR/31R-PPB12N00 a10vso140dr/32r-ppa12n00 A10VSO140DR-31R-PPB12N00 A10VSO18DFR/31R-PPA12N00 a10vso18dfr1/31r-ppa12n00 A10VSO18DFR1/31R-PPA-12N00 A10VSO18DFR1/31R-PPB12N00 a10vso18dfr1/31r-ppb12noo A10VSO18DFR31RPPA12N00 A10VSO18DR/31LPPA12NOO-S0169 a10vso18dr/31r-ppa12n00 A10VSO18DR/31R-PPB12N00 A10VSO18DR/53R-VDC12N00 A10VSO18DR\31R+A10VSO10DR\52R A10VSO18DRG/31R-PPA12N00 A10VSO28DFLR/31R-PPA12N00 A10VSO28DFR/31R-PPA12N00 A10VSO28DFR/31R-PSA12N00 a10vso28dfr1/31r-ppa12n00 A10VSO28DFR1/31R-PPA12N00-SO32 A10VSO28DR/31RPA12N00 A10VSO28DR/31R-PPA12N00 A10VSO28DR/31R-PPB12N00 A10VSO28DR/32R-PPA121V00 a10vso28drf1/31r-psa12n00 A10VSO45 A10VSO45DFLR1/3R-PSC62N00 A10VSO45DFR/31 A10VSO45DFR/31R-PPA1200 A10VSO45DFR/31R-PPA12N00 A10VSO45DFR1/31R-PPA12N00 A10VSO45DFR1/32R-PPB12N00 a10vso45dr/31r-ppa12n00 A10VSO45DR/31R-PPB12N00 A10VSO45DR/52R-PC12N00 A10VSO46 A10VSO71 A10VSO71DFLR/31R-PPA12N00 A10VSO71DFR/31R/PPA12N00 A10VSO71DFR/31R-PPA12K01 A10VSO71DFR/31R-PSC62K07 a10vso71dfr1/31r-ppa12kb5 A10VSO71DFR1/31R-PPA12N00 A10VSO71DFR1/31R-PPB12NOO A10VSO71DFR1/31R-PSA12N00 a10vso71dfr1/32r-vpb22u99 a10vso71dr/31r-ppa12n00 A10VSO71DR/31R-PPA-12N00 A10VSO71DR/31R-PPB12N00 A10VSO71DR131R-PPC12VOOM A11V 0130 a11v130 a11v190 A11V190DRS A1OVS071DFR1/31R-PPA12N00 A1OVSO45DFR1/31R-PPA12NOO A1OVSO71DFR1/31R-PPA12N00 A2F0107/61R-PPB05 A2F0125/61RL-PPB05 A2F023/61R-PAB05 A2F55R2P3 A2FO10/61R-PAB06?
