Na u kile ua nahana ka hore na ke lisebelisoa life tse sebelisoang bakeng sa bakete ea excavator?Sehloohong sena, re tla tšohla lisebelisoa tse sebelisoang ka ho fetisisa lithabeng, mahlakoreng, ho itšeha, matlo le meno a linkho tsa excavator.

Lithakhisa tsa Excavator

Lithakhisa tsa ho epa hangata li entsoe ka tšepe ea AISI 4130 kapa 4140.AISI 4000 letoto la tšepe ke chrome molybdenum tšepe.Chromium e ntlafatsa ho hanyetsa ho bola le ho thatafala, ha molybdenum e boetse e ntlafatsa matla le ho thatafala.

Nomoro ea pele, 4, e emela boemo ba tšepe le motsoako oa eona oa mantlha (tabeng ena, chromium le molybdenum).Nomoro ea bobeli ea 1 e emela peresente ea likarolo tsa motsoako, e bolelang ka 1% chromium le molybdenum (ka boima).Linomoro tse peli tsa ho qetela ke likhakanyo tsa khabone ka 0.01% increments, kahoo AISI 4130 e na le 0.30% carbon le AISI 4140 e na le 0.40%.

Tšepe e sebelisitsoeng mohlomong e 'nile ea phekoloa ka ho thatafala ha induction.Ts'ebetso ena ea kalafo ea mocheso e hlahisa sebaka se thata se nang le khanyetso (58 ho 63 Rockwell C) le bokahare bo bonolo ho ntlafatsa ho tiea.Hlokomela hore lihlahla hangata li entsoe ka thepa e ts'oanang le likhoele.Lithako tse ling tsa theko e tlaase li ka 'na tsa etsoa ho tloha ho AISI 1045. Ena ke tšepe ea carbon e mahareng e ka thatafalang.

Mahlakoreng a Bakete ea Excavator le Meeli e Sehang

Mahlakore a bakete le lehare hangata li entsoe ka poleiti ea AR.Lihlopha tse tsebahalang haholo ke AR360 le AR400.AR 360 ke tšepe e nang le carbon low alloy e sebelisitsoeng mocheso ho fana ka khanyetso e ntle ea ho apara le matla a matla a phahameng.AR 400 e boetse e phekoloa mocheso, empa e fana ka khanyetso ea ho apara le matla a phahameng a chai.Litšepe ka bobeli li thatafatsoa ka hloko le ho halefa ho fihlela boleng ba sehlahisoa sa bakete.Ka kopo hlokomela hore nomoro ka mor'a AR ke ho thatafala ha tšepe ea Brinell.

Shell ea Bakete ea Excavator

Li-Bucket housings hangata li entsoe ho tloha ASTM A572 Grade 50 (ka linako tse ling e ngotsoe A-572-50), e leng A high strong low low alloy steel.Tšepe e kopantsoe le niobium le vanadium.Vanadium e thusa ho boloka tšepe e le matla.Mokhahlelo ona oa tšepe o loketse likhetla tsa libakete kaha o fana ka matla a matle ha o ntse o le boima bo tlase ho litšepe tse bapisoang joalo ka A36.Hape ho bonolo ho tjheseletsa le ho bopeha.

Meno a Bakete ea Excavator

E le ho buisana ka hore na meno a libakete a entsoe ka eng, ke habohlokoa ho utloisisa hore ho na le litsela tse peli tsa ho etsa meno a libakete: ho lahla le ho qhekella.Meno a libakete a ka etsoa ka tšepe e tlase ea alloy e nang le nickel le molybdenum e le likarolo tse ka sehloohong tsa motsoako.Molybdenum e ntlafatsa ho thatafala le matla a tšepe 'me e ka boela ea thusa ho fokotsa mefuta e meng ea ho bola ha likoti.Nickel e ntlafatsa matla, ho tiea le ho thusa ho thibela kutu.Li ka 'na tsa etsoa ka tšepe ea ductile ea isothermal quenched e' nileng ea phekoloa mocheso ho ntlafatsa ho hanyetsa le ho matlafatsa matla.Meno a libakete a ferekaneng a boetse a entsoe ka tšepe ea alloy e entsoeng ka mocheso, empa mofuta oa tšepe o fapana ho tloha ho moetsi ho ea ho moetsi.Kalafo ea mocheso e ntlafatsa ts'ebetso ea ho apara le ho eketsa matla a tšusumetso.

Qetello

Libakete tsa excavator li entsoe ka lisebelisoa tse 'maloa tse fapaneng, empa lisebelisoa tsena kaofela ke tsa mofuta oa tšepe kapa oa tšepe.Mofuta oa thepa o khethoa ho latela hore na karolo e jarolloa le ho etsoa joang.
