Ngaphansi kokusetshenziswa okujwayelekile, isando se-excavator break sizosebenza cishe iminyaka emithathu, futhi kuzoba nokuncipha kokusebenza kahle komsebenzi. Lokhu kungenxa yokuthi emsebenzini, indawo yangaphandle ye-piston kanye ne-cylinder body wear, ukuze igebe lokuqala likhule, ukuvuza kwamafutha anengcindezi ephezulu kuyanda, ingcindezi iyancipha, okuholela ekutheni amandla omthelela wesando se-excavator break anciphe, futhi ukusebenza kahle komsebenzi kuyancipha.
Ezimweni zomuntu ngamunye, ngenxa yokusetshenziswa okungalungile ngu-opharetha, ukugqoka kwezingxenye kuyasheshisa. Isibonelo: ukugqokwa kwesikhashana komkhono womhlahlandlela ongenhla nangaphansi, ukulahleka komphumela oqondisayo, i-axis yenduku yokubhoboza nokutsheka kwepiston, ipiston emsebenzini wokushaya induku yokubhoboza, amandla angaphandle atholwe ubuso bokuphela. akuwona amandla aqondile, kodwa i-Angle ethile yamandla angaphandle kanye nomugqa ophakathi we-piston, amandla angakwazi ukubola abe ukusabela kwe-axial kanye namandla e-radial. Amandla e-radial abangela ukuthi i-piston iphambuke iye ohlangothini olulodwa lwesilinda, igebe lokuqala liyanyamalala, ifilimu kawoyela ibhujiswe, bese kwakheka ukungqubuzana okomile, okusheshisa ukuguga kwepiston kanye nembobo ku-cylinder block, futhi igebe phakathi kwepiston nesilinda block liyakhula, okuholela ekwenyukeni kokuvuza kanye nomthelela wesando se-excavator break uyancipha.
Lezi zimo ezimbili ezingenhla ziyizizathu eziyinhloko zokunciphisa ukusebenza kahle kwesando se-excavator break.
Kuwumkhuba ovamile ukushintsha isethi yamapiston nezigxivizo zikawoyela, kodwa ukumane umisele ipiston entsha ngeke kuyixazulule ngokuphelele inkinga. Ngenxa yokuthi isilinda sesigugile, ubukhulu bobubanzi bangaphakathi buye bukhulu, ububanzi bangaphakathi besilinda buye bandisa ukujikeleza kanye ne-taper, igebe phakathi kwe-cylinder ne-piston entsha lidlule igebe lokuklama, ngakho-ke ukusebenza kahle kwesando esiphukayo. ayikwazi ukubuyiselwa ngokugcwele, hhayi lokho kuphela, kodwa futhi ngenxa yokuthi i-piston entsha nesilinda esigugile isebenza ndawonye, ngenxa yokuthi isilinda sesigugile, ukukhwabanisa kwangaphandle kwanda, okuzosheshisa ukugqoka kwe-piston entsha. Uma umhlangano we-cylinder ophakathi ushintshwa, yiqiniso, kuwumphumela omuhle kakhulu. Kodwa-ke, i-cylinder block ye-excavator break hammer ibiza kakhulu kuzo zonke izingxenye, futhi izindleko zokushintsha umhlangano omusha we-cylinder azishibhile, kanti izindleko zokulungisa i-cylinder block ziphansi kakhulu.
Isilinda sesando se-excavator break is carburized in the production, izinga eliphezulu le-carburizing layer lingaba ngu-1.5 ~ 1.7mm, futhi ubulukhuni ngemva kokwelashwa kokushisa ngu-60 ~ 62HRC. Ukulungisa ukugaya kabusha, ukususa izimpawu zokuguga (okuhlanganisa nokuklwebheka), ngokuvamile kudingeka ukugaya 0.6~0.8mm noma ngaphezulu (uhlangothi 0.3~0.4mm), ungqimba lwangempela oluqinile lusengaba ngu-1mm, ngakho ngemva kokugaya kabusha isilinda, ubulukhuni bobuso buqinisekisiwe, ngakho-ke ukumelana nokugqoka kwendawo yangaphakathi yesilinda kanye nomkhiqizo omusha awuhlukile kakhulu, ukugqoka kwesilinda kungenzeka ukulungisa kanye.
Ngemva kokuba isilinda silungisiwe, ubukhulu bayo buzoshintsha. Ukuze kuqinisekiswe ukuthi amandla omthelela wokuklama wangempela ahlala engashintshile, kuyadingeka ukuhlela kabusha nokubala indawo yomgodi wangaphambili nangemuva we-cylinder. Ngakolunye uhlangothi, kuyadingeka ukuqinisekisa ukuthi isilinganiso sendawo ye-cavity yangaphambili nangemuva ihlala ingashintshiwe ngomklamo wokuqala, futhi indawo ye-cavity yangaphambili nangemuva nayo ihambisana nendawo yokuqala, ngaphandle kwalokho izinga lokugeleza lizoshintsha. . Umphumela uba ukuthi ukugeleza kwesando se-excavator break kanye nomshini wokuthwala akuhambisani ngokunengqondo, okuholela emiphumeleni emibi.
Ngakho-ke, i-piston entsha kufanele ilungiswe ngemuva kwe-cylinder block elungisiwe ukubuyisela ngokugcwele igebe lokuklama, ukuze ukusebenza kahle kwesando se-excavator break kungabuyiselwa.
