Sehloohong sena, re tla bua ka liphoso tse tloaelehileng ho potoloho ea hydraulic ea sesebelisoa se sebetsang sa loader. Sengoliloeng sena se tla aroloa ka lihlooho tse peli tse tla hlahlojoa.
Ketsahalo ea 1: Bakete kapa boom ha e tsamaee
Tlhahlobo ea mabaka:
1) Ho hloleha ha pompo ea Hydraulic ho ka khethoa ka ho lekanya khatello ea phallo ea pompo. Mabaka a ka bang teng a kenyelletsa ho sotheha kapa ho senyeha ha pompo ea shaft, ho potoloha ha pompo ho sa sebetse hantle kapa ho ts'oaroa, li-bearings li mafome kapa li khomaretsoe, ho lutla ho hoholo, letlapa le phaphametseng le kolobisitsoeng haholo kapa le behiloe, joalo-joalo.
2) Sefahla se koalehile 'me lerata le hlaha.
3) Pipe ea ho hula e robehile kapa motsoako oa pipe le pompo o hlephile.
4) Ho na le oli e nyane haholo ka tankeng ea mafura.
5) Sebaka sa tanka ea mafura se koetsoe.
6) Sephahla se seholo sa liphallelo se nang le mefuta e mengata se senyehile 'me se hlōleha.
Mokhoa oa ho rarolla bothata:Lekola pompo ea hydraulic, fumana sesosa, 'me u felise ho hloleha ha pompo ea hydraulic; hloekisa kapa u nke sebaka sa skrine ea sefe: hlahloba liphaephe, manonyeletso, masoba a tanka le valluu e kholo ea liphallelo ho felisa phoso.
Ketsahalo ea 2: Ho phahamisa Boom ho fokola
Tlhahlobo ea mabaka:
Lebaka le tobileng la ho phahamisa bofokoli ba boom ke khatello e sa lekaneng ka kamoreng e se nang rod ea boom hydraulic cylinder. Mabaka a ka sehloohong ke: 1) Ho na le ho lutla ho hoholo ka har'a pompo ea hydraulic kapa filthara e koetsoe, e leng se etsang hore ho be le ho se lekane ha oli ka pompo ea hydraulic. 2) Ho lutla ho tebileng ka hare le ka ntle ho etsahala tsamaisong ea hydraulic.
Lisosa tsa ho lutla ka hare li kenyelletsa: khatello e kholo ea valve ea ts'ireletso ea valve e khutlisetsang litsela tse ngata e fokotsehile haholo, kapa mokokotlo o moholo oa valve o khomaretsoe sebakeng se bulehileng ke litšila (seliba sa ntlha ea mantlha ea valve ea sefofane ke e bonolo haholo ebile e thijoa habonolo ke litšila; valve e khutlisetsang boom ka har'a valve ea litsela tse ngata e khomaretsoe sebakeng sa drainage, lekhalo pakeng tsa mokokotlo oa valve le lesoba la 'mele la valve le leholo haholo kapa valve ea tsela e le' ngoe ka har'a valve ha e e-s'o tiisetsoe ka thata; selikalikoe sa ho tiisa piston ea boom cylinder e senyehile kapa Seaparo se tebileng; boom cylinder barrel e apere haholo kapa e tsitsitsoe; lekhalo pakeng tsa konokono ea valve ea taolo ea phallo le 'mele oa valve e kholo haholo; mocheso oa oli o phahame haholo.
Ho batle phoso:
1) Sheba filthara, e hloekise kapa u e khutlisetse haeba e koetsoe; hlahloba le ho felisa sesosa sa mocheso o feteletseng oa oli, 'me u e nkele sebaka haeba oli e senyeha.
2) Sheba hore na valve e ka sehloohong ea tšireletso e khomaretsoe. Haeba e khomaretsoe, qhaqholla 'me u hloekise motsoako o moholo oa valve e le hore o ka tsamaea ka bolokolohi. Haeba phoso e ke ke ea felisoa, sebelisa valve e khutlisetsang mekhoa e mengata, potoloha nate e lokisoang ea valve e ka sehloohong ea tšireletso, 'me u shebe karabelo ea khatello ea tsamaiso. Haeba khatello e ka fetoloa ho boleng bo boletsoeng, phoso e hlile e felisoa.
3) Lekola hore na selikalikoe sa hydraulic cylinder piston sealing se lahlehetsoe ke ho tiisa: hulela cylinder ea boom tlase, ebe o tlosa hose e nang le khatello e phahameng ho tsoa lenonyeletsong la sekoti se se nang molamu, 'me u tsoele pele ho sebelisa valve e khutlisetsang morao. molamu oa piston oa boom cylinder ho ea pele. Kaha molamu oa piston o fihlile tlaase 'me ha o sa khona ho sisinyeha, khatello e ntse e eketseha. Ebe u sheba hore na ho na le oli e tsoang sebakeng sa oli. Haeba ho na le oli e nyenyane feela e tsoang, ho bolela hore lesale la ho tiisa ha lea hlōleha. Haeba ho na le phallo e kholo ea oli (ho feta 30mL / min), ho bolela hore lesale la ho tiisa le hlōlehile 'me le lokela ho nkeloa sebaka.
4) Ho ipapisitsoe le nako ea ts'ebeliso ea valve ea litsela tse ngata, e ka hlahlojoa hore na lekhalo pakeng tsa mokokotlo oa valve le lesoba la 'mele oa valve le leholo haholo. Lekhalo le tloaelehileng ke 0.01mm, 'me boleng ba moeli nakong ea tokiso ke 0.04mm. Arola le ho hloekisa valve ea li-slide ho felisa ho khomarela.
5) Sheba lekhalo pakeng tsa konokono ea valve ea taolo ea phallo le lesoba la 'mele oa valve. Boleng bo tloaelehileng ke 0.015 ~ 0.025mm, 'me boleng bo phahameng ha bo fete 0. 04mm. Haeba lekhalo le le leholo haholo, valve e lokela ho nkeloa sebaka. Sheba ho tiisoa ha valve ea tsela e le 'ngoe ka har'a valve. Haeba tiiso e fosahetse, sila setulo sa valve ebe u fetola mokokotlo oa valve. Sheba liliba ebe u li khutlisetsa haeba li holofetse, li le bonolo kapa li robehile.
6) Haeba lisosa tse ka holimo tse ka khonehang li tlosoa 'me phoso e ntse e le teng, pompo ea hydraulic e tlameha ho qhaqhoa le ho hlahlojoa. Bakeng sa pompo ea gear ea CBG e atisang ho sebelisoa mochining ona, haholo-holo hlahloba tumello ea ho qetela ea pompo, 'me ea bobeli u hlahlobe tumello ea meshing pakeng tsa likere tse peli le tumello ea radial pakeng tsa gear le khetla. Haeba lekhalo le le leholo haholo, ho bolela hore ho lutla ho hoholo haholo mme ka hona oli e lekaneng ea khatello e ke ke ea hlahisoa. Ka nako ena, pompo e kholo e lokela ho nkeloa sebaka. Lifahleho tse peli tse qetellang tsa pompo ea gear li tiisitsoe ka lipoleiti tse peli tsa mahlakoreng a tšepe tse kentsoeng ka motsoako oa koporo. Haeba motsoako oa koporo lipoleiting tse ka mahlakoreng o oa kapa o apere haholo, pompo ea hydraulic e ke ke ea khona ho fana ka oli e lekaneng ea khatello. Pompo ea hydraulic le eona e lokela ho nkeloa sebaka ka nako ena. Boloetse bo hlohlelletsa
7) Haeba phallo ea boom e fokola empa nkho e khutlela morao ka tloaelo, ho bolela hore pompo ea hydraulic, filthara, valve ea phallo ea phallo, valve e ka sehloohong ea tšireletso le mocheso oa oli ke ntho e tloaelehileng. Etsa bonnete ba le ho rarolla likarolo tse ling.
Ketsahalo ea 3: Ho hula ka libakete ho fokola
Tlhahlobo ea mabaka:
1) Pompo e kholo e hloleha 'me filthara e koalehile, e leng se bakang tlhahiso e sa lekaneng ea oli le khatello e sa lekaneng pompong ea hydraulic.
2) Sephahla se seholo sa tšireletso se hlōleha. Mokotla o moholo oa valve o khomaretsoe kapa tiiso ha e thata kapa taolo ea khatello e tlase haholo.
3) Valve ea ho laola phallo e hlōleha. Lekhalo le leholo haholo mme valve ea tsela e le 'ngoe ka har'a valve ha e e-so tiisetsoe ka thata.
4) Bakete e khutlisetsang li-valve konokono le lesoba la 'mele la li-valve li kholo haholo, li lutse sebakeng sa ho hula oli,' me nako ea ho khutla ha e sebetse.
5) Valve ea tšireletso e sebetsang ka makhetlo a mabeli e hlōleha. Mokotla o moholo oa valve o khomaretsoe kapa tiiso ha e thata.
6) Lesale la ho tiisoa ha nkho ea hydraulic cylinder e senyehile, e tsofetse haholo, 'me moqomo oa cylinder o tsitsitse.
Ho batle phoso:
1) Lekola hore na phahamiso ea boom e matla. Haeba ho phahamisa boom ho tloaelehile, ho bolela pompo ea hydraulic, filthara, valve ea ho laola phallo, valve e ka sehloohong ea tšireletso le mocheso oa oli ke ntho e tloaelehileng. Ho seng joalo, rarolla mathata ho latela mokhoa o hlalositsoeng ho Symptom 2.
2) Lekola lekhalo pakeng tsa konokono ea valafo e khutlisetsang bakete le lesoba la 'mele. Lekhalo la moeli le ka hare ho 0.04mm. Hloekisa valve ea li-slide ebe u lokisa kapa u fetola likarolo.
3) Harolla le ho hlahloba ho tiisa le ho feto-fetoha ha maemo pakeng tsa mokokotlo oa li-valve le setulo sa valve sa valve ea tšireletso e sebetsang ka makhetlo a mabeli le setsi sa valve le setulo sa valve sa tsela e le 'ngoe,' me u hloekise 'mele oa valve le mokokotlo oa valve.
4) Harola le ho hlahloba nkho ea hydraulic cylinder. E ka etsoa ho latela mokhoa oa tlhahlobo oa boom hydraulic cylinder e hlalositsoeng ka phoso 2.
Re tla boela re lokolle halofo ea bobeli ea litaba hamorao, kahoo lula u mametse.
Haeba u hloka ho rekalisebelisoa tsa thepa or lisebelisoa tsa letsoho tsa khale, o ka ikopanya le rona. CCMIE e tla u sebeletsa ka pelo eohle!
