195-71-71120 ARM
Pachida chogwirira ntchito cha ma bulldozer, mkono wogwirira ntchito (Arm) ndi gawo lalikulu-lonyamula katundu lomwe limalumikiza chimango ndi zigawo zogwirira ntchito (monga ndowa ndi zomasula nthaka), ndipo amadziwika kuti "skeleton of the working device". Imakwanitsa kukweza, kuzungulira ndi kuchita zina kudzera pa hydraulic drive, kudziwa mwachindunji kuchuluka kwa ntchito, katundu-kuthekera kwake ndi kusinthasintha kwa bulldozer.
matekinoloje ofunikira
Kugwira ntchito kwa ndowa: "mphamvu yayikulu" yotsitsa ndikutsitsa pansi
Mabuldoza okhala ndi zidebe (monga kukweza ma bulldozer) ali ndi mkono wogwirira ntchito ngati njira yothandizira chidebecho:
Mfundo yogwirira ntchito: Silinda ya boom imatambasula ndikubweza kuti mkono wogwirira ntchito ukweze ndikutsitsa, ndikuyendetsa chidebe kuti amalize kuzungulira kwa "kukweza fosholo pansi → kukweza → kutsitsa mozungulira". Utali ndi ngodya yokweza ya mkono wogwirira ntchito zimatsimikizira kutalika kwa ntchito ndi utali wotsitsa wa ndowa. Mwachitsanzo, potsitsa mumgodi, mkono wautali wogwira ntchito ukhoza kutsitsa zida kumagalimoto apamwamba.
Kusintha kwachipangidwe: Chidebe chogwiritsira ntchito chidebe nthawi zambiri chimapangidwa ngati gawo limodzi kapena lawiri (gawo lachiwiri likhoza kupindika kuti lichepetse kukula kwa mayendedwe), ndipo mphamvu ya mkono imayenera kufanana ndi mphamvu ya ndowa (nthawi zambiri 3-10m ³) kuonetsetsa kuti sichiwonongeka panthawi yonyamula katundu.
Zochitika zogwiritsira ntchito: kukweza ndi mayendedwe mu engineering ya Earthwork, kugwiritsira ntchito mtunda waufupi wa zida zamigodi, kusonkhanitsa zinthu pakukweza malo, ndi zina zambiri.
Kumasula ntchito: "kuthandizira kuphwanya" kwa mapangidwe olimba
Dzanja logwira ntchito la bulldozer lalikulu litha kusinthidwa ndi chipangizo chomasule dothi chophwanyira dothi lolimba, dothi lowundana, ndi mwala wopindika:
Mfundo yogwirira ntchito: Dzanja logwirira ntchito limayang'anira malo olowera nthaka ndi kuya kwa chipangizo chomasule nthaka kudzera mu silinda yamafuta. Dothi likamamasula nsonga ya mano ikhudza pansi, mkono wogwira ntchitoyo umakhala ndi mphamvu yophwanyira, kutembenuza silinda yamafuta kukhala mphamvu yolowera m'nthaka, ndikugawa nthaka.
Mawonekedwe: Dzanja logwira ntchito la chipangizo chomasula nthaka nthawi zambiri limakhala lalifupi komanso lalitali, ndikuwonjezeka kwa makulidwe a 20% mpaka 30%. The hinge point bushing imakhala ndi mphamvu yolimba kuti isavalidwe (yoyenera kuthamanga kwambiri-nthawi zambiri), ndipo mpando wolumikizira silinda yamafuta umalimbikitsidwa kuti usapirire mphamvu zazikulu za axial.
Kagwiritsidwe ntchito: Kusamalira kale-mankhwala asanamangidwe misewu, kuthyola dothi lapamwamba m'migodi, ndi kung'ambika kwa dothi lolimba pokonzanso minda.
