Nezve iyo hydraulic breaker, sezvatinoziva tese, iyo piston yemhedzisiro yakakosha mune rondedzero yezvakanyanya kukosha zvikamu.Kana iri kukundikana kwepiston, inowanzova yakanyanya, uye inowanzokonzera kukanganisa kwakakomba, uye marudzi ekukundikana anobuda mukusingaperi.Naizvozvo, HMB yakapfupisa zvikonzero zvakawanda zvekukundikana kwepiston.
1.Kukwenya panzvimbo yekushanda,Piston strain crack
Chikonzero:
● pasi pasi kuoma
Shandisa hardness tester kuyera kuomarara kwepakati (35 ≥ 45 ndiyo inogamuchirika kuoma kwepakati kukosha) ③Kana iri yakaderera pane 35 madhigirii kana kutopfuura madhigirii makumi maviri chete, mapistoni mahombe, kunyanya ma hydraulic breaker ane simba rakati kurei. kunyanya kunotsemuka pamusoro ④ Mushure mekutsemuka kuoneka, kushivirira kune rumwe rutivi kunowedzera mumakumi emawaya, zvichizoparadza mukaha wakajairika pakati pepiston necylinder, zvichikonzera kunetsa kwakakomba.
● Tsvina yakasanganiswa mumafuta e hydraulic
● Mukaha uri pakati pechibooreso chegwara remaoko (makwenzi ekumusoro neazasi) wakakurisa, uye sleeve yegwara inokundikana.
Kana iyo drill tsvimbo iri kushanda, axis inorerekera.Apo piston inorova tsvimbo yekuchera, inogamuchira simba rekuita rakarerekera, iro rinogona kukanganisa axial simba uye radial simba, uye radial simba rinogona kusundira piston kune rimwe divi, gaka rekutanga rinonyangarika, firimu remafuta rinoparadzwa, rakaoma. kupokana kunoumbwa pakati pehumburumbira nepiston pamusoro, uye nzvimbo yepiston inokweshwa semhedzisiro.
2.piston kuputsika
chikonzero:
① Dambudziko rezvinhu
Iyo carburized yakaderera-alloy simbi piston ndiyo yemukati chikonzero chekukanganisa kupera kwechiso chekuora mwoyo uye kuputika.
Musiyano wekuomarara pakati pepiston inorova chikamu uye chikamu chinorova chetsvimbo chekuomarara chinofanira kunge chakakodzera.
②Dambudziko rekurapa kupisa
Munguva yekugadzira kana kupisa kupisa, iyo piston zvinhu inoburitsa makatsemuka, ayo anowedzera kuputika kusvika aputsika pasi pechiito chekuchinjana kushushikana.
3.Piston ine gomba rakadzika, uye cylinder body ine point-to-point symmetrical longitudinal strain;
Chikonzero:
①Kupinda tsvina, zvichiita kuti piston irasikirwe nechiyero kumberi nekumashure, nepfungwa yekurereka musoro, zvichikonzera kunetsa.
② Cavitation, cavitation inowanzoitika muhumburumbira, kwete papiston.Cavitation ichaita gomba rakadzika dema, uye iyo yakawandisa zvinhu mairi ichave yakaora mukukurumidza kukanganiswa kweiyo hydraulic mafuta, uye iyo cylinder yese ichaomeswa.
③Makomba engura, sezvaratidzwa pamufananidzo haasi makomba.Ngura makomba anowanzo kukonzerwa nepiston zvinhu (semuenzaniso, vamwe vanogadzira vanoshandisa 42CRMO kana kungoshandisa 40CR nezvimwe zvinhu nekuda kwekumanikidzwa kwemusika) kana pakuchengeta, havana kuterera nekusundira piston muhumburumbira.Mumazuva ekunaya, Corrosion inokonzerwa kwenguva yakareba, uye ngura yeyero inoshanduka kuita ngura nhema uye pakupedzisira inova gomba.Kazhinji, chiitiko ichi chakajairika kune madiki uye madiki mabreaker anotanga kudonha oiri nguva yekugadzirisa isati yasvika.
KANA uine chimwe chinhu, ndapota inzwa wakasununguka kutibata! Ngatigadzirise dambudziko pamwe chete, huyai!!
