Honed Tube rau Hydraulic Lub tog raj kheej
Lub raj honed, uas feem ntau hu ua hydraulic lub tog raj kheej raj lossis lub tog raj kheej lub tog raj kheej, yog ib qho tseem ceeb thiab qhov tseeb - ua cov khoom uas ua rau lub cev tseem ceeb ntawm lub tog raj kheej hydraulic. Nws ua haujlwm raws li lub siab- uas muaj chamber thiab cov lus qhia rau lub piston thiab foob sib dhos. Nws lub luag haujlwm tseem ceeb yog tso cai kom du, ua haujlwm zoo, thiab xau-dawb linear txav ntawm lub piston nyob rau hauv siab. Qhov txawv feature ntawm cov khoom no yog nws sab hauv, uas yog tiav mus rau ib tug high℃ntawm precision los ntawm ib tug txheej txheem hu ua honing.
Hauj lwm lawm
Lub raj honed, uas feem ntau hu ua hydraulic lub tog raj kheej raj lossis lub tog raj kheej lub tog raj kheej, yog ib qho tseem ceeb thiab qhov tseeb - ua cov khoom uas ua rau lub cev tseem ceeb ntawm lub tog raj kheej hydraulic. Nws ua haujlwm raws li lub siab- uas muaj chamber thiab cov lus qhia rau lub piston thiab foob sib dhos. Nws lub luag haujlwm tseem ceeb yog tso cai kom du, ua haujlwm zoo, thiab xau-dawb linear txav ntawm lub piston nyob rau hauv siab. Qhov txawv feature ntawm cov khoom no yog nws sab hauv, uas yog tiav mus rau ib tug high℃ntawm precision los ntawm ib tug txheej txheem hu ua honing.
Honing yog txheej txheem abrasive machining uas ua rau tus ntoo khaub lig zoo -hatch nto qauv nyob rau sab hauv ntawm lub raj. Qhov no yog tiav siv honing pob zeb uas ib txhij tig thiab reciprocate nyob rau hauv lub raj bore. Cov lus tsa suab tshwj xeeb no tsim cov yam ntxwv zoo li lub kaum sab xis, uas yog qhov tseem ceeb rau kev ua haujlwm zoo. Tus ntoo khaub lig-hatch qauv no ua haujlwm rau ob lub hom phiaj tseem ceeb: nws khaws cov roj nplua nyeem kom ntseeg tau tias lubrication zoo ib yam ntawm cov piston seals, txo kev sib txhuam thiab hnav, thiab nws cuam tshuam cov kab mob microscopic, tiv thaiv lawv los ntawm khawb thiab ua rau cov ntsaws ruaj ruaj thiab piston.
Cov txiaj ntsig ntawm lub raj zoo honed yog dav. Ua ntej, nws muab qhov tshwj xeeb ntawm qhov chaw tiav nrog qhov nruab nrab roughness tsawg heev (Ra). Qhov no txo qis kev sib txhuam, txo qhov hnav ntawm cov ntsaws ruaj ruaj, thiab txhim khu kev ua haujlwm thiab kev ua haujlwm ntawm hydraulic system. Qhov thib ob, honing ua kom zoo dua qhov tseeb ntawm geometric, tswj kev ua siab ntev rau sab hauv txoj kab uas hla (ID) thiab ua tiav qhov tshwj xeeb ncaj thiab roundness. Qhov no tiv thaiv bypass to thiab ua kom zoo ib yam piston txav yam tsis muaj kev sib txawv. Thaum kawg, tus txheej txheem tsim ib tug nto nrog ib tug compressive residual kev nyuaj siab, uas yuav ua tau kom lub raj lub neej qaug zog thiab tsis kam mus rau siab.
Cov raj no feem ntau yog tsim los ntawm siab -lub zog, qis- carbon steel qib xws li ST52.3 lossis CK45. Txhawm rau txhim kho corrosion kuj thiab txo qhov kev sib txhuam, lawv feem ntau yog chrome-plated rau ntawm txoj kab uas hla (ID). Honed tubes yog cov qauv kev lag luam rau hydraulic thooj voos kheej kheej siv hauv kev thov tsis txaus ntseeg thoob plaws cov cuab yeej siv (excavators, bulldozers), cov tshuab ua liaj ua teb (tsheb laij teb, sib txuas), cov xovxwm, thiab cov khoom siv tuav. Lawv qhov tseeb yog qhov tseem ceeb rau lub zog, kev ntseeg tau, thiab kev ua haujlwm ntev ntawm tag nrho cov hydraulic system.
