Mabapi le sekhechana sa hydraulic, joalo ka ha bohle re tseba, piston ea tšusumetso e bohlokoa haholo lenaneng la likarolo tsa mantlha.Ha e le ho hlōleha ha piston, hangata ke eona e ngata ka ho fetisisa, 'me ka kakaretso e baka ho hlōleha ho tebileng,' me mefuta ea ho hlōleha e hlaha ka ho sa feleng.Ka hona, HMB e akaretsa lisosa tse 'maloa tsa ho hlōleha ha piston.
1.Mekhoa sebakeng se sebetsang, Piston strain crack
Lebaka:
● boima bo tlase ba holim'a metsi
Sebelisa teko ea boima ba 'mele ho lekanya boima ba mantlha (35 ≥ 45 ke boleng bo amohelehang ba nako ea boimana) ③Haeba e ka tlase ho likhato tse 35 kapa esita le ho feta likhato tse 20 feela, lipiston tse kholo, haholo-holo li-hydraulic breaker tse nang le tšusumetso e matla haholo. haholo-holo e atisang ho ba le mapheo a holim'a metsi ④ Ka mor'a hore mapetsong a hlahe, mamello ka lehlakoreng le leng e tla atoloha ka lithapo tse mashome, kahoo e senya lekhalo le tloaelehileng pakeng tsa piston le cylinder, e leng se bakang khatello e tebileng.
● Litšila tse tsoakiloeng ka har'a oli ea haeteroliki
● Lekhalo pakeng tsa letsoho la tataiso ea lithupa (lihlahla tse ka holimo le tse ka tlaase) le leholo haholo, 'me letsoho le tataisang lea hlōleha.
Ha molamu oa ho phunya o sebetsa, axis e sekametse.Ha piston e otla molamu oa ho phunya, e fumana matla a karabelo a sekametseng, a ka senyang matla a axial le matla a radial, 'me matla a radial a ka sutumelletsa piston ka lehlakoreng le leng, lekhalo la pele lea nyamela, filimi ea oli e senyehile, e omme. khohlano e thehoa lipakeng tsa silinda le bokaholimo ba piston, 'me bokaholimo ba piston boa hlajoa ka lebaka leo.
2. ho robeha ha piston
lebaka:
① Bothata ba lintho tse bonahalang
The carburized low-alloy steel piston ke sesosa se ka hare sa phello ea phello ea ho tepella maikutlo le ho phatloha.
Phapang ea boima pakeng tsa karolo e otlang ea piston le karolo e thata ea rod ea boro e lokela ho ba e loketseng.
②Bothata ba phekolo ea mocheso
Nakong ea phekolo ea ho qhekella kapa ea mocheso, thepa ea piston e hlahisa mapetsong, a atolosang mapetsong ho fihlela a robehile tlas'a ketso ea khatello ea maikutlo.
3.Piston e na le sekoti se tebileng, 'me' mele oa cylinder o na le ntlha-to-point symmetrical longitudinal strain;
Lebaka:
①Ho kenya litšila, ho etsa hore piston e lahleheloe ke botsitso ka pele le ka morao, ka mohopolo oa ho sekamisa hlooho, ho baka khatello.
② Cavitation, cavitation hangata e etsahala ka cylinder, eseng ka piston.Cavitation e tla baka lesoba le tebileng le letšo, 'me boitsebiso bo feteletseng ho eona bo tla senyeha ka tšusumetso e potlakileng ea oli ea hydraulic,' me cylinder eohle e tla senyeha.
③ Likoti tsa mafome, joalo ka ha ho bonts'itsoe setšoantšong ha se mekoti ea mafome.Likoti tsa mafome hangata li bakoa ke thepa ea piston (mohlala, baetsi ba bang ba sebelisa 42CRMO kapa ba sebelisa 40CR le lisebelisoa tse ling ka lebaka la khatello ea 'maraka) kapa ha ba boloka, ha baa ka ba ela hloko ho sutumetsa piston ka silindara.Matsatsing a lipula, Corrosion e bakoa ke nako e telele, 'me mafome a mosehla a fetoha mafome a matšo 'me qetellong a fetoha sekoti.Ka kakaretso, ketsahalo ena e tloaelehile bakeng sa li-breaker tse nyenyane le tse nyenyane tse qalang ho tsoa oli pele ho nako ea tlhokomelo.
HAEBA u na le letho, ka kopo ikutloe u lokolohile ho ikopanya le rona! Ha re rarolle bothata hammoho, tloo!!
