Rexroth A11VO190 A11VO260 Hydraulic Piston Twj Series A11VO190LRDH1/11R-NZD12K83 Rexroth Hydraulic Twj

Kev xaiv kom raug ntawm cov kua dej hydraulic yuav tsum muaj kev paub txog kev ua haujlwm kub hauv kev sib raug zoo rau qhov kub thiab txias: inan qhib Circuit Court lub tank kub.Lub hydraulic kua yuav tsum tau xaiv kom lub khiav hauj lwm viscosity nyob rau hauv lub khiav hauj lwm kub ntau yam nyob rau hauv lub optimumrange (νopt.) - pom qhov ntxoov ntxoo ntawm daim duab xaiv.Peb pom zoo kom xaiv cov chav kawm viscosity siab dua hauv txhua kis.Piv txwv: Ntawm qhov ntsuas kub ntawm X degree qhov ntsuas kub ntawm 140 degree F (60 degree) tau teeb tsa. Nyob rau hauv qhov zoo tshaj plaws kev khiav hauj lwm viscosity ntau yam (νopt; qhov chaw ntxoov ntxoo) no sib raug rau cov chav kawm viscosity VG 46 thiab VG 68; yuav tsum tau xaiv: VG 68 txwv ntawm viscosity rangeThe limiting values for viscosity is as follows: νmin=42 SUS (5 mm2/s) Short-term (t < 3 min) at max. ua perm. kub ntawm tmax=240 degree F (ntxiv rau 115 degree ).νmax=7400 SUS (1600 mm2/s) Lub sij hawm luv (t < 3 min) Thaum txias pib (p Tsawg dua lossis sib npaug rau 435 psi (30 bar), n Tsawg dua lossis sib npaug li 1000 rpm, tmin=-40 degree F (-40 degree )). Tsuas yog rau kev pib tsis muaj kev thauj khoom. Optimum khiav hauj lwm viscosity yuav tsum mus txog nyob rau hauv approx. 15 feeb.Nco ntsoov tias qhov siab tshaj plaws hydraulic kua dej kub ntawm 240 degree F (115 degree) yuav tsum tsis txhob siab tshaj nyob rau hauv ib qho chaw twg (xws li nyob rau hauv lub bearing cheeb tsam). Qhov kub nyob rau hauv lub bearing cheeb tsam yog - nyob ntawm seb lub siab thiab ceev - mus txog 9 degree F (5 K) siab tshaj qhov nruab nrab qhov ntsuas qhov ntsuas kub.Tshwj xeeb yog tsim nyog rau qhov ntsuas kub ntawm -40 degree F ({28}} degree ) thiab -13 degree F (-25 degree ) (lub caij txias pib), thov hu rau peb.Rau cov ncauj lus kom ntxaws txog kev siv qhov kub thiab txias, saib RE 90300-03-B.

Hydraulic kua Ua ntej pib qhov kev npaj, thov mus saib peb cov ntaub ntawv RE 90220 (mineral oil), RE 90221 (ib puag ncig siv tau hydraulic kua) thiab RE 90223 (HF hydraulic fluids) rau cov ncauj lus kom ntxaws txog kev xaiv cov kua dej hydraulic thiab kev ua haujlwm. Lub twj tso kua mis sib txawv AA11VO tsis haum rau kev ua haujlwm nrog HFA, HFB thiab HFC. Yog tias HFD lossis ib puag ncig tau siv cov kua dej hydraulic, cov kev txwv ntawm cov ntaub ntawv kev lag luam thiab cov ntsaws ruaj ruaj tau hais hauv RE 90221 thiab RE 90223 yuav tsum tau ua raws li qhov ntsuas kub ntawm lub nplhaib foob lub nplhaib FKM ncej foob yog tso cai rau cov ntaub ntawv ntws kub ntawm {{6 }} degree F txog 240 degree F (-25 degree rau ntxiv rau 115 degree ). Lus Cim Rau cov ntawv thov hauv qab no -13 degree F ({11}} degree ), NBR ncej foob nplhaib yog tsim nyog (tso cai kub ntau: -40 degree F txog 194 degree F (-40 degree mus rau ntxiv 90 degree). Lub xeev NBR ncej foob nplhaib nyob rau hauv cov ntawv ntshiab nyob rau hauv qhov kev txiav txim.Flushing rooj plaub Yog hais tias ib tug sib txawv twj tso kua mis nrog tswj unit EP, HD, DR los yog stroke limiter (H., U., ) yog ua nyob rau hauv lub sij hawm ntev. (t> 10 min) nrog rau xoom lossis kev khiav hauj lwm siab <220 psi (15 bar), yaug cov ntaub ntawv los ntawm cov chaw nres nkoj "T1", "T2" lossis "R" yog qhov tsim nyog
