Ib qho ruaj khov, swashplate-tsim lub cev muaj zog rau cov tsav uas yuav tsum tuav lub zog hauv qab load. Ntawm no yog nws cov haujlwm ua haujlwm tau teev tseg txoj hauv kev uas tus kws tshaj lij xaiv tau nyeem nws: torque tiv thaiv siab, ntws tawm tsam nrawm, tom qab ntawd tus lej sau npe.
Torque tiv thaiv siab
M=Vg × Δp / 20π · full displacement · η=1
| 100 bar | 7 0,8nm |

Qhov rai ua haujlwm
FLUID
HLP roj rau DIN 51524, 20/18/15 ISO 4406 los yog ntxuav; 19/17/14 hauv qab 10 mm²/s ntawm qhov chaw nres nkoj ntws.
VISCOSITY
16-36 mm² / s rau kev ua haujlwm siab; 400-10 mm² / s hauv kev pabcuam; 7 mm² / s luv luv; 1600 mm² / s txias pib.
HLOOV TSHIAB
10 bar yam tsawg kawg nkaus ntawm qhov chaw nres nkoj thauj khoom; 2 bar kiag li nyob rau sab rov qab; 2 bar zoo li qub ntawm L / L1.
THEMAL CEILING
110℃siab tshaj dej kub, ntsuas ntawm qhov chaw nres nkoj LX, nrog FKM sealing khoom.
Cov lus nug xaiv
Qhov siab ntawm 45 mus txog 150 Nm?
Kev daws cov qauv torque rau siab muab txog 212 bar ntawm tag nrho cov hloov pauv, hauv kev xav. Cov tshuab tiag tiag zaum siab dua vim tias cov tshuab ua haujlwm -hydraulic efficiency ib txwm qis dua, yog li npaj lub luag haujlwm taw tes me ntsis saum daim duab ntawd.
37 los yog 45 - tib lub tsev, txawv lub cev muaj zog?
Zoo tib yam 17 kg ncej thiab zoo tib yam ncej txhav; dab tsi hloov yog pawg rotating. Lub 45 yuav kwv yees li ntawm 21% ntau dua torque thiab muab li ntawm 5% ntawm qhov ceev tshaj plaws, yog li qhov kev xaiv los ntawm seb tus tsav yog torque - txwv lossis ceev - txwv.
Puas yog lub cev muaj zog tiv thaiv kev thauj khoom sai sai?
Lub siab tuaj yeem tsim los yog lwj mus txog 16000 bar / s thiab angular acceleration raug tso tawm rau 4000 rad / s². Circuits uas thim rov qab sai sai yog vim li no tau txais, yog tias cov plag tsev siab raug hwm thiab rov qab tsis tuaj yeem tawg.
Qhia rau A10FM 45
Xa kev sib hloov, ncej kawg, chaw nres nkoj style, valve thiab sensor xaiv ntxiv rau kom muaj nuj nqis rau kev lees paub, tus nqi thiab lub sijhawm khoom xa tuaj.
