Kodi bulldozer imakwanitsa bwanji kulamulira bwino?

Valavu yoyendetsa ya njira zambiri ndiyofunika kwambiri.

Kuwongolera bwino dongosolo la hydraulic ndikofunikira kwambiri kuti bulldozer igwire bwino ntchito. Monga valavu yayikulu yowongolera dongosolo la hydraulic, valavu yoyendetsa njira zambiri ikukhala chinthu chofunikira kwambiri pakudziwa momwe bulldozer imagwirira ntchito. Kodi imalola bwanji kuyenda kosinthasintha kwa tsamba la bulldozer mu bulldozer yayikulu?

1. Magawo Oyambira Amathandizira Kugwira Ntchito Kokhazikika

Valavu yoyendetsa zinthu zambiri imapereka kusinthasintha kwabwino, yokhala ndi mphamvu yolowera mpaka 50 bar ndi mphamvu yobwerera ya T-port ya 3 bar, kuonetsetsa kuti mphamvu ya hydraulic system ikuyenda bwino pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito. Valavu iyi ndi yoyenera kugwiritsa ntchito mafuta amchere okhala ndi kukhuthala kwa 10-380 mm/s. Imagwira ntchito kutentha pakati pa -20°C ndi 80°C, ndipo imafuna ukhondo wa mafuta a NAS Class 8, kuonetsetsa kuti ntchito yake ndi yodalirika kwa nthawi yayitali. Magawo enaake alembedwa patebulo ili pansipa:

2. Kapangidwe ka Kapangidwe ka Zinthu Kamapangitsa Kuti Zinthu Zizigwira Ntchito

Valavu yoyendetsa zinthu zambiri imakhala ndi thupi la valavu, pakati pa valavu, kasupe, polowera mafuta, ndi cholumikizira. Imawongolera bwino kayendedwe ka mafuta mwa kusintha malo a spool. Pa ntchito yoyendetsa bulldozing, woyendetsa amakankhira chogwirira (cholumikizidwa ndi njira yogwirira ntchito ya valavu ya phazi), chomwe chimasuntha pakati pa valavu, ndikutsegula dera loyenderana ndi mafuta. Mafuta a hydraulic amayendetsa silinda, zomwe zimathandiza bulldozer kukweza, kuwerama patsogolo, kuwerama kumbuyo, ndikusuntha kumanzere ndi kumanja. Mwachitsanzo, pokonza pansi, kukonza bwino valavu yotsetsereka kumalola kuwongolera bwino ngodya ya tsamba. Pogwira ntchito ndi zipangizo, kusintha mwachangu dera la mafuta kumalola kukweza ndi kutsitsa bwino chidebe, zomwe zimapangitsa kuti mayendedwe ovuta akhale osavuta komanso owongolera.

3. Kuwongolera Mwanzeru Kumawonjezera Kugwira Ntchito Bwino

Pakati pa valavu pakonzedwa bwino kwambiri kuti pakhale kuyenda bwino kwa mafuta a hydraulic. Pogwira ntchito m'malo otsekeka, kuyenda pang'ono kumalola bulldozer kusuntha pang'onopang'ono ndikukonza bwino malo a tsamba. Polinganiza malo otseguka, kukankha mwachangu chogwirira kumayatsa ndikutseka dera la mafuta ndi kuyenda kwakukulu, kuonetsetsa kuti bulldozer ikugwira ntchito bwino. Kaya ndi yotsetsereka pang'ono kapena yotsetsereka kwambiri, wogwiritsa ntchito amatha "kuloza ndi kugunda," kuchepetsa ntchito zobwerezabwereza ndikukweza magwiridwe antchito omanga, kusintha ogwiritsa ntchito kuchoka pa "mphamvu yankhanza" kupita ku "kulamulira kolondola."

4. Kudalirika ndi Kulimba Kuonetsetsa Kuti Ntchito Ikugwira Ntchito Mosalekeza

Pogwiritsa ntchito zipangizo zapamwamba komanso njira zamakono zopangira, thupi la valavu limagwira ntchito bwino kwambiri potseka ndipo silikutuluka madzi ngakhale pakagwa kupanikizika kwa nthawi yayitali komanso kusintha kwa kayendedwe ka nthawi ndi nthawi. Zigawo monga masipure ndi ma valve cores sizitopa ndipo zimagwira ntchito bwino ngakhale m'mikhalidwe yovuta yogwirira ntchito (monga fumbi ndi matope pamalo omanga) bola mafutawo atakhala oyera. Izi zimachepetsa nthawi yogwira ntchito komanso kukonza chifukwa cha kulephera kwa ma valavu, kuonetsetsa kuti ntchito ikupita patsogolo mosalekeza komanso kuchepetsa ndalama zokonzera zida, kuonetsetsa kuti ntchito yomanga "yosasiya". Izi zimapangitsa kuti ikhale "choyendetsa bwino" chodalirika pamalo omanga.
