Mukushandiswa kwakajairwa, sando yekuchera inoputika ichashanda kweanenge makore matatu, uye pachave nekudzikiswa kwekuita basa. Izvi zvinodaro nekuti mubasa, iyo yekunze yepiston uye silinda yemuviri inopfeka, kuitira kuti gaka rekutanga riwedzere, iyo yakanyanya-kudzvanywa mafuta inodonha inowedzera, kudzvanywa kunodzikira, zvichikonzera kuti simba rekupwanya nyundo ridzikire, uye kushanda kwekushanda kunoderedzwa.
Muzviitiko zvega, nekuda kwekushandiswa zvisina kunaka nemushandi, kupfeka kwezvikamu kunowedzera. Semuenzaniso: kupfeka kwekuchinja kweiyo yepamusoro uye yezasi giraidhi sleeve, kurasikirwa kweinotungamira mhedzisiro, axis yechiboorero uye piston tilt, piston mubasa rekurova dhiri tsvimbo, simba rekunze rinogamuchirwa nekuguma kwechiso. haisi simba rakamira, asi imwe Angle yesimba rekunze uye mutsara wepakati wepiston, simba rinogona kuderedzwa kuita axial reaction uye radial simba. Simba reradial rinoita kuti piston itsaukire kune rimwe divi recylinder block, gaka rekutanga rinonyangarika, firimu remafuta rinoparadzwa, uye kukweshana kwakaoma kunogadzirwa, izvo zvinomhanyisa kupfeka kwepiston uye gomba mucylinder block, uye gap pakati pepiston uye cylinder block rinowedzera, zvichikonzera kuwedzera kudonha uye kukanganisa kweiyo yekuchera nyundo yekupwanya kunoderedzwa.
Mamiriro maviri ari pamusoro apa ndiwo zvikonzero zvikuru zvekudzikisira kushanda kweiyo excavator break sando.
Yakajairika tsika kutsiva seti yepiston uye zvisimbiso zvemafuta, asi kungotsiva pisitoni nyowani hakuzogadzirise zvachose dambudziko. Nekuti silinda yakapfekwa, saizi yemukati yedhayamita yave yakakura, dhayamita yemukati yecylinder yakawedzera kutenderera uye taper, gaka riri pakati pecylinder nepiston nyowani rakapfuura gap rekugadzira, saka kugona kwesando inopwanya. haigoni kudzorerwa zvakakwana, kwete izvozvo chete, asiwo nokuti piston itsva uye cylinder yakasakara inoshanda pamwe chete, nokuti cylinder yave yakasakara, kunze kwekunze kwepamusoro kwakawedzera, izvo zvichakurumidza kupfekedzwa kwepistoni itsva. Kana iyo yepakati silinda musangano yakatsiviwa, hongu, ndiyo yakanakisa mhedzisiro. Zvisinei, cylinder block of the excavator break hammer ndiyo inodhura kupfuura zvikamu zvose, uye mari yekutsiva cylinder itsva haina kudhura, nepo mari yekugadzirisa cylinder block yakaderera.
Humburumbira yesando yekuchera inoputika yakabikwa mukugadzirwa, iyo yakakwira mwero weiyo carburizing layer ingangoita 1.5 ~ 1.7mm, uye kuomarara mushure mekupisa kupisa i60 ~ 62HRC. Kugadzirisa kugayazve, kubvisa mavanga ekupfeka (kusanganisira zvikwambo), kazhinji anoda kukuya 0.6 ~ 0.8mm kana zvakadaro (padivi 0.3 ~ 0.4mm), iyo yekutanga yakaomeswa layer ichiri inenge 1mm, saka mushure mekugaya zvakare silinda, kuomarara kwepamusoro kunovimbiswa, saka kusakara kwemukati we cylinder uye chigadzirwa chitsva hachina kusiyana zvakanyanya, kupfeka kwe cylinder kunokwanisika kugadzirisa kamwe chete.
Mushure mokunge silinda yakagadziriswa, ukuru hwayo hunosungirwa kuchinja. Kuti uone kuti iyo yekutanga dhizaini yekukanganisa simba inoramba isina kuchinjika, zvinodikanwa kugadzirisa zvakare uye kuverenga kumberi uye kumashure mhango nzvimbo ye cylinder. Kune rumwe rutivi, zvinodikanwa kuve nechokwadi kuti chiyero chenzvimbo yepamberi neshure chinoramba chisina kuchinjwa nekugadzirwa kwepakutanga, uye nzvimbo yepamberi neshure inopindirana nenzvimbo yepakutanga, kana zvisina kudaro chiyero chekuyerera chichachinja. . Mhedzisiro yacho ndeyokuti kuyerera kwenyundo yekuchera nyundo uye muchina wekutakura hauna kufananidzwa zvine musoro, zvichikonzera mhedzisiro yakaipa.
Nokudaro, piston itsva inofanira kugadzirirwa mushure mekugadzirisa cylinder block kuti idzorere zvizere gaka rekugadzira, kuitira kuti kushanda kwekushanda kwechifukidzo chenyundo kudzoserwe.
