Kodi tiyenera kuchita chiyani ngati kelly bar yagwera pansi panthawi yomanga chobowolera chozungulira?

Ogwira ntchito ambiri azida zobowolera zozungulirandakumana ndi vuto labala la kellykutsika pansi panthawi yomanga. Ndipotu, izi sizikugwirizana ndi wopanga, chitsanzo, ndi zina zotero. Ndi vuto lofala kwambiri. Mukagwiritsa ntchito chobowola chozungulira kwa nthawi ndithu, mutabwezeretsa chogwirira ntchito pamalo osalowerera, kelly bar imatsetsereka pansi mtunda winawake. Nthawi zambiri timatcha izi kutibala la kellyKutsetsereka pansi. Ndiye tingathetse bwanji vuto la kelly bar kutsetsereka pansi?

1. Njira yowunikira

(1) Yang'anani valavu ya solenoid 2

Onetsetsani ngati valavu ya solenoid 2 yatsekedwa bwino: chotsani mapaipi awiri amafuta opita ku valavu ya solenoid 2 pa mota, ndikutseka madoko awiri amafuta kumapeto kwa mota ndi mapulagi awiri motsatana, kenako gwiritsani ntchito makina akuluakulu a winch. Ngati ikugwira ntchito bwino, imasonyeza vuto Kuchokera ku valavu ya solenoid 2 siitsekedwa bwino; ngati ikadali yachilendo, ndikofunikira kuyang'ana zigawo zake.

(2) Chongani loko ya hydraulic

Yang'anani ngati pali vuto ndi loko ya hydraulic: choyamba sinthani masilinda awiri a loko, ngati sakugwira ntchito, kenako chotsani loko kuti muyang'ane mosamala. Ngati chifukwa sichikupezeka, loko yokonzeka ingagwiritsidwe ntchito poyesa kuyiyika kuti mudziwe chomwe chachititsa kulephera. Chifukwa loko ya hydraulic ya chogwirira chothandizira ndi yofanana ndi ya chogwirira chachikulu, loko ya chogwirira chothandizira ikhozanso kubwerekedwa ndikusinthidwa imodzi ndi imodzi kuti mudziwe mtundu wa loko yayikulu. Ngati palibe vuto ndi maloko onse awiri, pitani ku cheke yotsatira.

(3) Yang'anani mafuta a chizindikiro cha brake

Yang'anani liwiro la mafuta a chizindikiro cha brake ndikusweka: chogwirira chamakono chobowola, kuyenda kwa mafuta a chizindikiro kumatha kusinthidwa, ndiko kuti, nthawi yomwe winch yayikulu imatulutsa brake ikhoza kusinthidwa. Chifukwa chake, pamitundu iwiri ya chogwirira chobowola, kuyenda kwa mafuta a chizindikiro kumatha kusinthidwa kudzera mu valavu yake yowongolera. Ngati momwe makina amagwirira ntchito sikuli bwino, ndikofunikira kuwona ngati chitoliro cha mafuta a chizindikiro cha brake chatsekedwa. Ngati magawo owunikira awa ndi abwinobwino, mutha kupitiliza kuwona

(4) Chongani buleki:

Onetsetsani ngati pisitoni ya brake ikuyenda bwino pamzere wogwirira ntchito, ndipo ikonzeni kapena isintheni malinga ndi chifukwa cha kulephera.

Kelly bar wachobowolera chozunguliraChimakhazikika pa ng'oma yayikulu yokwezera kudzera pa chingwe cha waya, ndipo chitoliro chobowolera chikhoza kukwezedwa kapena kutsitsidwa mofanana pamene ng'oma kapena chingwe cha waya chatulutsidwa. Mphamvu ya chozungulira imachokera ku mota yayikulu yokwezera yomwe yachepetsedwa mphamvu nthawi zambiri. Kuyima kwake kumachitika chifukwa cha brake yomwe imayikidwa mwachindunji pa decelerator. Pakukweza kapena kutsitsa kwabala la kelly, ngati chogwirira ntchito chabwezedwa pakati Ngatibala la kellySizingatheke kuyima nthawi yomweyo ndikutsika mtunda winawake musanayime, pali zifukwa zitatu zomwe zimapangitsa izi:

1. Kuchedwa kwa mabuleki;

2. Ma hydraulic locks awiri omwe ali pa malo otulukira injini amalephera, ndipo injiniyo singasiye kuzungulira nthawi yomweyo chifukwa cha mphamvu ya chingwe cha waya;

Chifukwa chachitatu chomwe timachinyalanyaza ndi chomwechi.chobowolera chozungulirakhalani ndibala la kellyntchito yotulutsa. Ntchitoyi imaperekedwa ndi valavu ya solenoid kuti itulutse mafuta a chizindikiro cha brake, kenako valavu ya solenoid imalumikizidwa ku injini yayikulu kudzera m'mapaipi awiri amafuta. Malo olowera mafuta ndi malo otulukira injini yokwezera mafuta amaonetsetsa kuti chobowola chaching'ono chozungulira nthawi zonse chingathe kukhudzana ndi malo ogwirira ntchito ndikukhala ndi mphamvu inayake panthawi yobowola. Muzochitika zina zogwirira ntchito, valavu ya solenoid imadula mapaipi awiri amafuta omwe amatsogolera ku malo olowera mafuta ndi malo otulukira mafuta a injini. Ngati kulekanitsidwa sikuchitika nthawi yake, vuto lomwe latchulidwa pamwambapa lidzachitika.
