Mugukoresha bisanzwe, gucukura inyundo bizakora imyaka igera kuri itatu, kandi hazabaho kugabanuka kumikorere. Ni ukubera ko mu kazi, ubuso bwo hanze bwa piston na silinderi umubiri wambara, ku buryo icyuho cyambere cyiyongera, amavuta y’umuvuduko ukabije wiyongera, umuvuduko ukagabanuka, bikavamo ingaruka zingufu za excavator yamennye inyundo zigabanuka, kandi imikorere myiza iragabanuka.
Mubibazo byihariye, kubera gukoresha nabi uwabikoresheje, kwambara ibice byihuta. Kurugero: kwambara kwinzibacyuho yo hejuru yo hepfo no hepfo yo kuyobora, gutakaza imbaraga zo kuyobora, umurongo winkoni ya drill na piston ihengamye, piston mumurimo wo gukubita inkoni ya drillage, imbaraga zo hanze zakiriwe mumaso yanyuma ntabwo ari imbaraga zihagaritse, ariko Inguni runaka yingufu zo hanze n'umurongo wo hagati wa piston, imbaraga zirashobora kubora mo reaction ya axial nimbaraga za radiyo. Imbaraga za radiyo zitera piston gutandukana kuruhande rumwe rwa silinderi, icyuho cyambere kirazimira, firime yamavuta irasenyuka, kandi havuka ubwumvikane bwumye, byihutisha kwambara piston nu mwobo uri muri blindingi, na icyuho kiri hagati ya piston na silinderi cyiyongereye, bigatuma imyanda yiyongera kandi ingaruka zo kumena inyundo ziragabanuka.
Ibihe bibiri byavuzwe haruguru nimpamvu nyamukuru zo kugabanya imikorere yimashini icukura inyundo.
Ni ibisanzwe gusimbuza piston hamwe na kashe ya peteroli, ariko gusimbuza piston nshya ntabwo bizakemura burundu ikibazo. Kuberako silinderi yambarwa, ubunini bwimbere bwa diameter bwabaye bunini, diameter yimbere ya silinderi yongereye umuzenguruko na taper, ikinyuranyo hagati ya silinderi na piston nshya cyarenze icyuho cyagenwe, bityo imikorere yo kumena inyundo ntishobora kugarurwa byuzuye, sibyo gusa, ariko nanone kubera ko piston nshya na silinderi yambarwa ikorana, kubera ko silinderi yambarwa, ububobere bwo hanze bwiyongereye, bizihutisha kwambara piston nshya. Niba inteko ya silinderi yo hagati isimbuwe, birumvikana, nigisubizo cyiza. Nyamara, guhagarika silinderi yo kumena inyundo ni yo ihenze cyane mu bice byose, kandi ikiguzi cyo gusimbuza inteko nshya ya silinderi ntabwo gihenze, mugihe ikiguzi cyo gusana icyuma cya silinderi ari gito.
Silinderi yo kumena inyundo yamenetse ikarubura mu musaruro, urwego rwo hejuru rwurwego rwa carburizing rugera kuri 1.5 ~ 1.7mm, kandi ubukana nyuma yo kuvura ubushyuhe ni 60 ~ 62HRC. Gusana ni ukongera gusya, kuvanaho ibimenyetso byo kwambara (harimo no gushushanya), muri rusange bigomba gusya 0,6 ~ 0.8mm cyangwa birenga (uruhande 0.3 ~ 0.4mm), igice cyambere cyakomanze kiracyari nka 1mm, bityo nyuma yo kongera gusya silinderi, Ubuso bwo hejuru bwizewe, kubwibyo kwihanganira kwambara hejuru yimbere ya silinderi nibicuruzwa bishya ntabwo bitandukanye cyane, kwambara silinderi birashoboka gusana rimwe.
Iyo silinderi imaze gusanwa, ingano yayo igomba guhinduka. Kugirango tumenye neza ko imbaraga zambere zishushanya imbaraga zidahinduka, birakenewe ko dusubiramo kandi tukabara umwanya wimbere ninyuma ya silinderi. Ku ruhande rumwe, birakenewe kwemeza ko igipimo cyubuso bwimbere yinyuma ninyuma kidahinduka hamwe nigishushanyo mbonera cyambere, kandi ubuso bwimyanya yimbere ninyuma nabwo burahuza nakarere kambere, naho ubundi umuvuduko woguhinduka uzahinduka . Igisubizo nuko urujya n'uruza rwa excavator rumena inyundo kandi imashini itwara idahuye neza, bikavamo ingaruka mbi.
Kubwibyo, piston nshya igomba gutegurwa nyuma yo gusana silinderi yasanwe kugirango igarure byimazeyo icyuho cyabugenewe, kugirango imikorere yakazi yo gucukura inyundo isubizwe.
