Banyere onye na-agbaji hydraulic, dị ka anyị niile maara, piston mmetụta dị mkpa na ndepụta nke ihe kachasị mkpa. N'ihe banyere ọdịda nke piston, ọ na-abụkarị nke kachasị, na n'ozuzu ya na-akpata ọdịda dị njọ, na ụdị ọdịda na-apụta na njedebe na-adịghị agwụ agwụ. Ya mere, HMB achịkọtala ọtụtụ ihe kpatara ọdịda piston.
1.Scratches n'elu arụ ọrụ, Piston nje mgbawa
Ihe kpatara ya:
● isi ike dị ala
Jiri a hardness tester tụọ ike nke isi (35 ≥ 45 bụ ihe na-anabata ike ike etiti oge uru) ③Ọ bụrụ na ọ bụ ala karịa 35 degrees ma ọ bụ ọbụna naanị ihe karịrị 20 degrees, nnukwu pistons, karịsịa hydraulic breakers na dịtụ nnukwu mmetụta ike, na-adịkarị mfe n'elu cracks ④ Mgbe cracks apụta, na n'akụkụ nke ga-adaba n'ebe ahụ ga-enwe ike ibibi site n'otu ebe ahụ. n'etiti piston na cylinder, na-akpata nsogbu siri ike.
● Agwakọta adịghị ọcha na mmanụ hydraulic
● Oghere dị n'etiti ogwe ntụ ntụ ntụ (osisi elu na nke ala) buru ibu nke ukwuu, na aka uwe nduzi na-ada ada.
Mgbe mkpuru osisi na-arụ ọrụ, axis na-atụgharị. Mgbe piston na-akụtu mkpanaka ahụ, ọ na-enweta ike mmeghachi omume na-achọsi ike, nke nwere ike imebi ike axial na ike radial, na ike radial nwere ike ịkwanye piston n'otu akụkụ, oghere mbụ ahụ na-apụ n'anya, ihe nkiri mmanụ na-ebibi, esemokwu akọrọ na-etolite n'etiti cylinder na piston elu, na piston elu na-akpụcha ya.
2.piston agbaji
ihe kpatara ya:
① Nsogbu ihe onwunwe
The carburized ala alloy ígwè piston bụ n'ime ime nke mmetụta ọgwụgwụ ihu ịda mbà n'obi na cracking.
Ọdịiche siri ike dị n'etiti akụkụ piston na-egbu egbu na akụkụ siri ike nke mkpanaka ahụ kwesịrị ekwesị kwesịrị ekwesị.
②Nsogbu ọgwụgwọ okpomọkụ
N'oge a na-emepụta ma ọ bụ na-ekpo ọkụ na-ekpo ọkụ, ihe piston na-emepụta ihe mgbawa, nke na-amụba mgbawa ahụ ruo mgbe ha na-agbaji n'okpuru omume nke nrụgide ọzọ.
3.The piston nwere olulu miri emi, na cylinder ahụ nwere a n'ókè-na-atụ symmetrical longitudinal strain;
Ihe kpatara ya:
① Ịbanye adịghị ọcha, na-eme ka piston ghara itule n'ihu na azụ, na echiche nke ịgbatị isi, na-akpata nsogbu.
② Cavitation, cavitation na-emekarị na cylinder, ọ bụghị na piston. Cavitation ga-eme ka oghere ojii dị omimi, na oke ihe dị na ya ga-emebi na mmetụta ngwa ngwa nke mmanụ hydraulic, na cylinder dum ga-agbaze.
③Mmiri nchara, dị ka egosiri na foto a abụghị olulu nchara. A na-emekarị olulu nchara site na ihe piston (dịka ọmụmaatụ, ụfọdụ ndị na-emepụta na-eji 42CRMO ma ọ bụ jiri 40CR na ihe ndị ọzọ n'ihi nrụgide ahịa) ma ọ bụ mgbe ha na-echekwa, ha egeghị ntị na ịkwanye piston n'ime cylinder. N'ụbọchị mmiri ozuzo, a na-akpata corrosion ruo ogologo oge, nchara na-acha odo odo na-aghọkwa nchara ojii ma mesịa ghọọ olulu. N'ozuzu, ihe a na-emekarị maka ndị na-agbaji obere na obere ndị na-amalite ịmịpụ mmanụ tupu oge nhazi.
Ọ BỤRỤ na ị nwere ihe ọ bụla,biko nweere onwe gị ịkpọtụrụ anyị!Ka anyị dozie nsogbu ahụ ọnụ, bịanụ!!
