Ngaphantsi kokusetyenziswa okuqhelekileyo, isando sokuqhawula i-excavator siya kusebenza malunga neminyaka emithathu, kwaye kuya kubakho ukunciphisa ukusebenza kakuhle. Oku kungenxa yokuba emsebenzini, umphezulu wangaphandle wepiston kunye ne-cylinder body ukunxiba, ukuze umsantsa wangaphambili unyuke, ukuvuza kweoyile enoxinzelelo oluphezulu kuyanda, uxinzelelo luyancipha, okukhokelela kukuncipha kwamandla ehamile ye-excavator break, kwaye ukusebenza kakuhle kuyancipha.
Kwiimeko zomntu ngamnye, ngenxa yokusetyenziswa ngokungafanelekanga ngumqhubi, ukunxiba kwamacandelo kukhawuleziswa. Umzekelo: ukunxitywa kwenguqu yomkhono wesikhokelo ongasentla nangaphantsi, ukulahleka kwesiphumo esikhokelayo, i-axis yentonga ye-drill kunye ne-piston tilt, ipiston emsebenzini wokubetha intonga yokubhola, amandla angaphandle afunyenwe bubuso bokugqibela. ayingomandla othe nkqo, kodwa i-Angle ethile yamandla angaphandle kunye nomgca ophakathi wepiston, amandla anokuchithwa kwi-axial reaction kunye ne-radial force. Amandla eradial abangela ukuba ipiston ijike iye kwelinye icala lebhlokhi yesilinda, umsantsa wokuqala uyanyamalala, ifilimu yeoli iyatshatyalaliswa, kwaye ukukhuhlana okomileyo kwenziwa, okukhawulezisa ukuguga kwepiston kunye nomngxuma kwibhloko yesilinda, kwaye Umsantsa phakathi kwepiston kunye nebhlokhi ye-cylinder yanda, okukhokelela ekuvuzeni okwandisiweyo kunye nefuthe lesando sekhefu le-excavator liyancitshiswa.
Ezi meko zimbini zingasentla zezona zizathu zokunciphisa ukusebenza kakuhle kwesando sokuqhawula i-excavator.
Yinto eqhelekileyo ukubuyisela isethi yeepiston kunye nezitywina zeoyile, kodwa ukutshintshela ipiston entsha akuyi kuyicombulula ngokupheleleyo ingxaki. Ngenxa yokuba i-cylinder igugile, ubukhulu bangaphakathi bobukhulu buye bukhulu, ububanzi bangaphakathi be-cylinder bunyuse ukujikeleza kunye ne-taper, isithuba phakathi kwe-cylinder kunye nepiston entsha idlulile i-gap yoyilo, ngoko ke ukusebenza kwesando esaphukileyo. ayinakubuyiselwa ngokupheleleyo, kungekhona nje kuphela, kodwa ngenxa yokuba i-piston entsha kunye ne-cylinder egugileyo isebenza kunye, ngenxa yokuba i-cylinder igugile, i-rough surface yangaphandle iye yanda, eya kukhawulezisa ukunxiba kwepiston entsha. Ukuba indibano ye-cylinder ephakathi ithathelwa indawo, ngokuqinisekileyo, isiphumo esihle. Nangona kunjalo, ibhloko ye-cylinder ye-excavator break hammer iyona nto ibiza kakhulu kuzo zonke iindawo, kwaye iindleko zokutshintsha indibano entsha ye-cylinder ayincinci, ngelixa iindleko zokulungisa i-cylinder block ziphantsi.
I-cylinder ye-excavator break hammer i-carburized kwimveliso, inqanaba eliphezulu le-carburizing layer li malunga ne-1.5 ~ 1.7mm, kwaye ubunzima emva kokunyanga kobushushu yi-60 ~ 62HRC. Ukulungiswa kukuphinda ugaye, ukuphelisa iimpawu zokugqoka (kubandakanywa nemikrwelo), ngokubanzi kufuneka ukugaya i-0.6 ~ 0.8mm okanye kunjalo (icala le-0.3 ~ 0.4mm), umaleko owenziwe lukhuni usekho malunga ne-1mm, ngoko emva kokugaya kwakhona isilinda, ukuqina komphezulu kuqinisekisiwe, ngoko ke ukunyanzeliswa komgangatho wangaphakathi we-cylinder kunye nemveliso entsha ayifani kakhulu, ukunxiba kwe-cylinder kunokwenzeka ukulungisa kanye.
Emva kokuba i-cylinder ilungisiwe, ubukhulu bayo buya kutshintsha. Ukuze kuqinisekiswe ukuba amandla empembelelo yoyilo lwangaphambili ahlala engatshintshi, kuyimfuneko ukuyila kwakhona kunye nokubala indawo yangaphambili nangemuva yecavity yesilinda. Ngakolunye uhlangothi, kuyimfuneko ukuqinisekisa ukuba umlinganiselo wendawo yomqolo wangaphambili nangemuva uhlala ungatshintshi kunye noyilo lwangaphambili, kunye nommandla wecala langaphambili nangemuva lihambelana nendawo yokuqala, ngaphandle koko izinga lokuhamba liya kutshintsha. . Isiphumo kukuba ukuhamba kwesando sokuqhawula i-excavator kunye nomatshini wokuthwala awuhambelani ngokufanelekileyo, okubangelwa yimiphumo emibi.
Ngoko ke, i-piston entsha kufuneka ilungiswe emva kwebhloko ye-cylinder elungisiweyo ukubuyisela ngokupheleleyo i-gap yokuyila, ukwenzela ukuba ukusebenza kakuhle kwesando sokuqhawula i-excavator kunokubuyiselwa.
