Forestry hydraulic log grapples thiab trailers feem ntau ua haujlwm nyob rau hauv tandem nyob rau hauv hnyav hnyav; Lub hauv paus ntawm lawv cov kev saib xyuas tuaj yeem raug sau tseg raws li hauv qab no: rau kev sib tsoo, qhov ua kom pom tseeb yog nyob rau hauv hydraulic system thiab lubrication, thaum lub trailer, qhov tseem ceeb yog nyob rau hauv cov iav khiav thiab cov qauv kev ncaj ncees.
Ua ntej- thiab Tom Qab- Kev Tshawb Fawb Kev Ua Haujlwm (Kev soj ntsuam niaj hnub)
Qhov no yog qhov tseem ceeb tshaj plaws tseem ceeb tshaj plaws; siv sijhawm tshaj li kaum feeb ntawm kev tshuaj xyuas tuaj yeem tiv thaiv feem ntau qhov kev xav tsis thoob.
Kev kuaj xyuas kua dej thiab lim dej: Ua ntej pib thiab tom qab ua tiav kev ua haujlwm txhua hnub, xyuas tias cov roj cav, cov kua dej hydraulic, cov dej txias, thiab cov roj theem nyob hauv cov qauv. Cov ntxaij lim dej muaj qhov ua rau txhaws hauv qhov chaw hnyav; ntxuav cov lim dej txhua hnub tom qab ua haujlwm (siv cov cua compressed los ntawm sab hauv tawm) thiab hloov cov khoom txhaws tam sim ntawd.
Cov Ntsiab Lus Lubrication: Lub log rub lub pins, cov pob qij txha, thiab lub hauv paus slewing yog siab -qhov chaw hnav. Roj yuav tsum tau siv tsis tu ncua rau cov khoom no siv rab phom roj; Kev sib txhuam qhuav ntawm cov pins yog thawj qhov ua rau grapple tsis ua haujlwm.
Kev soj ntsuam cov qauv thiab Hydraulic Line: Saib xyuas cov welds ntawm lub boom thiab grapple rau cov kab nrib pleb, thiab xyuas cov khoom siv rau deformation. Tib lub sijhawm, ua tib zoo tshuaj xyuas hydraulic hoses thiab fittings rau cov dej xau, cov cim ntawm kev laus, lossis hnav.
Kev soj ntsuam hauv qab / txav mus los: Rau lub log tsheb, xyuas tias lub log tsheb siab yog qhov tseeb thiab tshuaj xyuas qhov kev txiav los yog bulges.
Trailer-Kev soj ntsuam tshwj xeeb: Tshawb xyuas cov ncej trailer rau deformation los yog tawg, xyuas kom meej tias nres nres, thiab xyuas kom meej tias lub teeb thiab kev sib txuas mechanisms (hitch/coupling rau lub tsheb towing) muaj kev ruaj ntseg thiab txhim khu kev qha.
Txhua 250 teev Kos lossis hloov cov roj lim dej hydraulic; tshuaj xyuas hydraulic hoses rau kev laus los yog tawg; lubricate lub viav vias puag thiab iav khib.
Txhua 500 teev Hloov cov roj hydraulic thiab lim cov ntsiab lus (qhov no yog qhov tseem ceeb tshaj plaws ntawm hydraulic system txij nkawm); huv radiator thiab roj txias fins; xyuas thiab nruj tag nrho cov bolts.
Txhua 1,000 teev Ua ib qho kev tshuaj xyuas tag nrho ntawm lub twj tso kua mis hydraulic thiab lub cev muaj zog ua haujlwm thiab lub zog siab.
Ntev- lub sij hawm cia (ntau tshaj 1 lub hlis) Ua tib zoo ntxuav cov cuab yeej; siv cov tshuaj tiv thaiv- xeb roj rau cov hlau nplaum; retract hydraulic lub tog raj kheej piston pas nrig; pib lub cav thiab txav lub tshuab tsawg kawg ib hlis ib zaug los tiv thaiv lub log deformation thiab roj teeb tawm.
Ob peb lub tswv yim kho kom zoo
Hydraulic roj kub yog ib qho tseem ceeb: Thaum lub sij hawm ib txwm ua hauj lwm, hydraulic roj kub yuav tsum tau khaws cia ntawm 30℃thiab 80 degree. Yog tias qhov kub thiab txias dhau lawm, nres lub tshuab kom kuaj xyuas lub tshuab hluav taws xob txhaws lossis cov cim qhia tias lub sijhawm dhau mus.
Hloov cov hniav txhuam hniav kom sai: Yog tias cov hniav txhuam hniav pom hnav ntau dua 10% lossis ib qho -feem peb ntawm lawv qhov profile, lawv yuav tsum tau kho los ntawm vuam lossis hloov tam sim; tsis ua li ntawd tuaj yeem ua rau tsis muaj zog tuav kev ua haujlwm lossis txawm tias muaj kev puas tsuaj rau lub tog raj kheej hydraulic.
Ua tib zoo saib xyuas cov dej huv: Thaum refueling lossis ntxiv cov roj hydraulic, xyuas kom meej tias cov cuab yeej thiab cov chaw nres nkoj tau huv si kom tsis txhob muaj cov kab mob nkag mus rau hauv lub cev. Tsis txhob sib xyaw cov roj hydraulic ntawm cov npe sib txawv lossis cov lus qhia tshwj xeeb.
Tsis txhob tuav rawv: Log grapples feature ntev, slender caj npab; siv lawv los nias rau ntawm, ram, los yog cov ntaub ntawv pry yog nruj me ntsis txwv tsis pub, vim qhov no yuav yooj yim deform cov yam ntxwv Cheebtsam los yog puas hydraulic cylinders. Tsis tas li ntawd, ib txwm ua nws tus cwj pwm kom thim rov qab cov khoom tawm ua ntej tsav lub tshuab, vim tias tsis ua li ntawd yog qhov ua rau muaj xwm txheej.
Khaws ib daim ntawv teev cov khoom siv yooj yim los sau cov hnub thiab sijhawm ua haujlwm ntawm txhua qhov kev pabcuam; qhov no ua tau zoo tiv thaiv kev tu ncua tsis tu ncua thiab txhawb nqa lub tshuab rov muag tus nqi.
