Hauv cov tshuab hluav taws xob hydraulic, radial piston twj thiab axial piston twj yog ob lub thev naus laus zis, ua haujlwm sib txawv ntawm daim ntawv thov nrog lawv cov qauv tsim tshwj xeeb thiab kev ua haujlwm zoo. Txawm hais tias ob leeg paub txog kev hloov pauv ntawm lub zog ntawm lub zog los ntawm kev sib txuas lus ntawm lub piston, muaj qhov sib txawv tseem ceeb hauv lawv cov qauv sab hauv, cov yam ntxwv ua haujlwm thiab cov xwm txheej siv tau.
Cov txheej txheem tseem ceeb sib txawv: "radial" thiab "parallel" kev npaj ntawm pistons
1. Hydraulic radial piston twj tso kua mis: cov pistons yog radially faib
Cov yam ntxwv ntawm tus qauv: Cov pistons tau teem rau hauv lub hnub qub duab raws li radial kev taw qhia ntawm tus tsav ncej (zoo ib yam li lub log spokes), perpendicular mus rau lub ntsiab ncej.
Lub hauv paus ntsiab lus ua haujlwm: Lub piston nyob ze rau ntawm lub nplhaib eccentric cam (Cam Nplhaib) los ntawm kev quab yuam centrifugal lossis lub tshuab thawb. Raws li lub rotor tig, lub piston reciprocates nyob rau hauv lub radial qhov ua kom tiav cov roj suction thiab roj siab txheej txheem.
Cov khoom tseem ceeb: eccentric cam nplhaib, rotor lub tog raj kheej, faib ncej.

Xaus: Yog tias qhov kev xav tau siab tshaj 500 bar, lub twj tso kua mis radial yog qhov kev xaiv nkaus xwb; yog tias nws qis dua 400 bar, lub twj tso kua mis axial yog tus nqi ntau dua.
2. Flow stability thiab suab nrov
Radial twj tso kua mis: tsawg dua plungers (feem ntau yog 5-7), loj ntws pulsation, suab nrov (ntau tshaj 80 dB).
Axial twj tso kua mis: ntau plungers (7-9 los yog ntau tshaj), smoother flow output, qis suab nrov (70-75 dB).
Daim ntawv thov cuam tshuam: Axial twj yog nyiam rau cov suab nrov-sensitive scenarios (xws li cov cuab yeej kho mob thiab cov cuab yeej siv tshuab precision).
3. Kev ua tau zoo thiab kev tswj tsis tau
Radial twj tso kua mis:
Kev siv tshuab ua haujlwm siab (92% +), tab sis kev hloov pauv tsis yooj yim, cam eccentricity hloov, teb qeeb.
Haum rau kev hloov pauv ruaj khov lossis qis-ceev thiab siab-siab.
Axial twj:
High volumetric efficiency (95% +), hloov pauv hloov pauv tswj (los ntawm kev kho lub kaum sab xis ntawm lub phaj swash), thiab cov lus teb ceev ceev.
Haum rau kev tswj hwm qhov sib txawv ntawm qhov ceev thiab lub zog txuag hluav taws xob (xws li excavators thiab cua zog sib txawv pitch systems).
4. Lub neej thiab kev saib xyuas
Radial twj tso kua mis: qauv yooj yim, muaj zog muaj kuab paug tsis kam, haum rau hnyav ib puag ncig (xws li mining machinery).
Axial twj tso kua mis: Lub phaj swash thiab plunger khub muaj qhov yuav tsum tau ua rau cov roj huv huv thiab xav tau kev pom zoo (NAS 1638 Chav Kawm 6 lossis siab dua).

Radial twj tau pom cov ntsiab lus loj hlob tshiab hauv lub zog tauj dua tshiab (xws li tidal power generation hydraulic systems).
Radial piston twj thiab axial piston twj sawv cev rau ob txoj kev xav ntawm hydraulic technology:
Radial twj yog "cov neeg ua haujlwm fais fab" tsim rau ultra-siab siab thiab muaj kev ntseeg siab;
Axial twj yog "tag nrho cov neeg ua si" nrog kev ua haujlwm zoo dua, tswj tau thiab compactness.
