Peb muab Sauer Axial Piston Variable Displacement Pumps series 90 ntawm txoj cai tig 90R030 90R042 90R075 90R100 90R130 90R180 90R250 thiab sab laug tig twj tso kua mis 90L030 90L042 90L075 90L100 90L130 90L180 90L250 Pump. 127-4589
Fture:
Series 90 axial piston hloov pauv hloov pauv cov twj tso kua mis yog lub txaj txaj tsim nrog kev hloov pauv hloov pauv, thiab yog npaj rau kev siv hluav taws xob kaw.
Tus nqi ntws yog proportional rau lub twj tso kua mis input ceev thiab hloov chaw.
Cov tom kawg yog infinitely adjustable ntawm xoom thiab siab tshaj plaws hloov chaw.
Flow kev taw qhia yog thim rov qab los ntawm tilting lub swashplate mus rau sab nraud ntawm qhov nruab nrab (zero displacement) txoj hauj lwm.
Hydraulic kua
Ua ntej pib qhov kev npaj, thov mus saib peb cov ntaub ntawv RE 90220 (cov roj ntxhia), RE 90221 (ib puag ncig siv tau cov kua dej hydraulic) thiab RE 90223 (HF hydraulic fluids) rau cov ncauj lus kom ntxaws txog kev xaiv cov kua dej hydraulic thiab daim ntawv thov. 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: nyob rau hauv ib qho qhib Circuit Court lub tank kub. Cov kua dej hydraulic yuav tsum raug xaiv kom qhov kev khiav hauj lwm viscosity nyob rau hauv kev khiav hauj lwm kub nyob rau hauv qhov zoo tshaj plaws ntau yam - 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 F (X degree) kev khiav hauj lwm kub ntawm 140 degree F (60 degree) yog teem. Nyob rau hauv qhov zoo tshaj plaws kev khiav hauj lwm viscosity ntau (qhov chaw ntxoov ntxoo) no sib raug rau cov chav kawm viscosity VG 46 los yog VG 68; xaiv: VG 68.
Thov nco ntsoov: Cov ntaub ntawv ntws kub, uas cuam tshuam los ntawm lub siab thiab ceev, yog ib txwm siab dua lub tank kub. Tsis muaj qhov taw tes hauv qhov system yuav kub siab dua 240 degree (115 degree) rau qhov ntau thiab tsawg 5 txog 200 lossis 195 degree F (90 degree) rau qhov ntau thiab tsawg 250 txog 500.
Yog tias cov xwm txheej saum toj no tsis tuaj yeem tswj hwm vim muaj kev ua haujlwm tsis zoo, peb pom zoo kom yaug cov ntaub ntawv ntawm qhov chaw nres nkoj U (loj 250 txog 500).
