Ngaphansi kokusetshenziswa okujwayelekile, i-Excavator ikhebula isando izosebenza cishe iminyaka emithathu, futhi kuzoba nokwehliswa kokusebenza kahle komsebenzi. Lokhu kungenxa yokuthi kulo msebenzi, ingaphezulu langaphandle lomzimba wepiston kanye nesilinda se-pisto ukugqoka, ukuze igebe langempela liyakhuphuka, ukuncipha kwamafutha aphezulu kuyakhuphuka, ukucindezela kuncipha amandla wesando sokungenisa i-hall, futhi ukusebenza kahle kuyancipha.
Ezimweni ngazinye, ngenxa yokusetshenziswa okungafanele ngu-opharetha, ukugqokwa kwezingxenye kuyasheshiswa. Isibonelo: Ukugqokwa kwesikhashana komhlahlandlela ongenhla nesingaphansi komhlahlandlela, ukulahleka komphumela wokuqondisa, i-axis yenduku yokushaya, kepha i-piston etholwa ngomugqa wokushaya, kepha amandla athile okushisa awona amandla okuqeda, kepha amandla aphansi we-piston, amandla angavunyelwa yi-axial kanye ne-radial Force. I-radial Force ibangela ukuthi i-piston iphambuke ohlangothini lwesilinda, igebe langempela liyanyamalala, futhi igebe lakhiwe, okuvinjelwe ukugqokwa kwesando se-cylinder kanye nomthelela wesando sekhefu sombiwe.
Lezi zimo ezimbili ezingenhla yizizathu eziphambili zokwehliswa kokusebenza kwesando sekhefu.
Kungumkhuba ojwayelekile ukufaka esikhundleni seqoqo lamaPistons kanye Nezimpawu Zoyela, kepha umane ungene esikhundleni se-piston entsha ngeke siyixazulule ngokuphelele inkinga. Ngoba isilinda sesigqokile, usayizi wangaphakathi wobubanzi usuphenduke umkhulu, ububanzi be-cylinder bukhuphule ukuzuliswa kanye ne-piston entsha, ngoba i-cylinder egqokile igqoke ndawonye, ngoba ubuqili bangaphandle buye bakhuphukile, okuyinto izosheshisa ukugqokwa kwe-piston entsha. Uma umhlangano wesilinda esiphakathi uthathelwa indawo, yiqiniso, kungumphumela omuhle kakhulu. Kodwa-ke, i-cylinder block ye-ractivator break hamndo ibiza kakhulu kuzo zonke izingxenye, futhi izindleko zokufaka esikhundleni somhlangano omusha wesilinda azishibhile, kanti izindleko zokulungisa ibhulokhi yesilinda ziphansi.
Isilinda se-Excavator Break Hammer sidilizwa ngokukhiqizwa, izinga eliphakeme le-carburing ungqimba licishe libe ngu-1.5 ~ 1.7mm, kanye nobulukhuni ngemuva kokwelashwa okushisa ngu-60 ~ 62hRC. Ukulungisa ukugaya kabusha, ukuqeda amamaki okugqoka (kufaka phakathi amamaki e-Wear), ngokuvamile adinga ukugaya i-0.6 kanye.
Ngemuva kokuthi isilinda silungiswa, usayizi waso nakanjani uzoshintsha. Ukuze uqinisekise ukuthi i-Original Design Umthelela amandla ihlala ingashintshiwe, kuyadingeka ukuhlela kabusha nokubala indawo yangaphambili nangemuva le-cavity yesilinda. Ngakolunye uhlangothi, kuyadingeka ukuqinisekisa ukuthi isilinganiso sendawo esingemuva nangasemuva sihlala singashintshiwe ngomklamo wokuqala, futhi indawo ye-cavity yangaphambili nangemva kwalokho iguqulwa nendawo yasekuqaleni, uma kungenjalo inani lokugeleza lizoshintsha. Umphumela uba ukuthi ukugeleza kwesando sokungenisa isando futhi umshini wokuthwala awufaniswa, okuholela emiphumeleni emibi.
Ngakho-ke, i-piston entsha kufanele ilungiswe ngemuva kokuthi i-cylinder cylinder block elungisiwe ukuze ibuyise igebe lokuklama ngokugcwele, ukuze ukusebenza kahle kwesando sekhefu ukuhlukana kungabuyiselwa.
