Iibhomu zelori zempompo zekhonkrithi zithembele kakhulu kwiisilinda zehydraulic ukufezekisa ukuphakamisa okuchanekileyo kunye nozinzo, ukwandisa, kunye nokusonga iintshukumo. Ezi zisilinda zisebenza phantsi koxinzelelo oluphezulu, imithwalo enzima, kunye neemeko zokusebenza ezinzima (ezifana nokuvezwa kwintsalela yekhonkrithi, uthuli, kunye nokuguquguquka kweqondo lokushisa), ukwenza ukugcinwa rhoqo kunye nokulungiswa kwangexesha kubalulekile ukukhusela ukusilela ngokukhawuleza kunye nokuqinisekisa ukhuseleko lokusebenza. Eli nqaku lichaza amanyathelo aphambili kunye neengqwalasela zobugcisa zokulungiswa kweesilinda ze-hydraulic ze-concrete pump booms zeloli, ukugubungela ukulungiswa kwangaphambili, ukuchithwa, ukuhlolwa, ukutshintshwa kwecandelo, ukuhlanganisana, kunye nokuvavanya emva kokulungiswa.

1. ULungiselelo lwangaphambili: uKhuseleko kunye nokuLungela iSixhobo

Ukhuseleko yeyona nto iphambili phambi kokuqala nawuphi na umsebenzi wokulungisa. Okokuqala, misa ilori yempompo yekonkile kumhlaba osicaba, oqinileyo kwaye ubambe isiqhoboshi sokupaka. Yehlisa i-boom kwindawo ezinzileyo ethe tye (okanye sebenzisa isakhelo senkxaso ukuba i-boom ayinakuthotywa) ukukhulula uxinzelelo kwi-cylinder ye-hydraulic. Cima i-injini yelori kwaye ukhuphe ibhetri ukunqanda ukusebenza ngengozi kwenkqubo ye-hydraulic. Emva koko, khulula uxinzelelo olushiyekileyo kwisekethe ye-hydraulic: khulula ngokuthe chu imibhobho yeoli edibeneyo ye-cylinder (usebenzisa i-wrench ene-torque limiter) ngelixa ubeka i-pan yeoli engezantsi ukuqokelela i-oyile ye-hydraulic evuzayo, uqinisekisa ukuba akukho-high-pressure oil sprays ngaphandle ukwenza ukwenzakala.

Ukulungiselela izixhobo, qokelela izixhobo ezikhethekileyo ukunqanda ukonakalisa amacandelo achanekileyo. Izixhobo eziyimfuneko zibandakanya: isethi yezitshixo ze-torque (ezinoluhlu lwe-0-500 N · m, zilungele ukuqinisa iinkcukacha ezahlukeneyo zeebholiti), i-hydraulic cylinder disassembly stand (ukulungisa i-cylinder stably ngexesha lokuqhaqha), i-piston rod puller (ukususa ngokukhuselekileyo i-piston kwi-cylinder barrel ecocekileyo njenge-cylinder barrel icocekile). iivalve), umhloli woburhalarhume obuphezulu (ukukhangela udonga lwangaphakathi lombhobho we-cylinder kunye nomphezulu wentonga ye-piston), kunye nesethi yeendawo ezitshintshileyo (njengamatywina, amakhonkco e-O, amakhonkco othuli, kunye nemikhono yesikhokelo, ekufuneka ihambelane nemodeli ye-cylinder-umz. i-fluororubber ukumelana noxinzelelo oluphezulu kunye nokubola kweoli).

2. Ukuchithwa kwe-Hydraulic Cylinder: Inyathelo ngenyathelo kunye noThintelo lomonakalo

Hlukanisa isilinda kwindawo yokusebenzela ecocekileyo, engenathuli (okanye sebenzisa isigqubuthelo sothuli ukuba usebenza ngaphandle) ukuthintela ungcoliseko ukuba lungangeni kwi-hydraulic system. Ulandelelwano lwe-disassembly kufuneka lulandele uyilo lwesakhiwo se-cylinder ukuphepha ukuguqulwa kwecandelo:

1. Susa uQhagamshelwano lwangaphandle: Sebenzisa i-socket wrench ukukhupha i-oyile yokungena kunye nemibhobho yokuphuma kwi-cylinder's end caps. Phawula umbhobho ngamnye kunye nokudibanisa kunye neleyibhile (umzekelo, "I-Inlet Pipe - Rod End") ukuze ugweme ukudibanisa kakubi ngexesha lokudibanisa kwakhona. Gxuma izibuko zemibhobho kunye nemingxuma yeoli yesilinda ngeeplastiki ezicocekileyo zokukhusela uthuli okanye i-debris ukuba ingangeni.
2. Khubaza i-End Cap kunye nePiston Rod: Lungisa i-cylinder barrel kwi-stand disassembly stand. Sebenzisa i-torque wrench ukuze ukhulule iibholiti ezidibanisa i-cap end end (isiphelo sentonga) kwi-cylinder barrel-sebenzisa i-torque ngokulinganayo (umzekelo, i-80-120 N · m ye-M16 bolts) ukukhusela i-cap end in tilting. Emva kokususa iibholiti, sebenzisa i-rubber mallet ukucofa i-cap yesiphelo ngobunono kwaye uyikhuphe ngokuthe tye. Emva koko, tsala kancinci intonga yepiston (enepiston encanyathiselwe) ngaphandle kwe-cylinder barrel, unqande ukukrwela umphezulu wentonga yepiston kumda we-cylinder barrel.
3. Hlukanisa Amacandelo Angaphakathi: Hlukanisa i-piston kwi-piston rod ngokususa i-nut yokuvala (sebenzisa i-spanner kunye ne-non-slip pad ukukhusela intonga ye-piston ekujikelezeni). Khupha indibano yetywina (kubandakanya itywina eliphambili, i-backup ring, kunye ne-buffer seal) kwi-piston kunye ne-end cap-sebenzisa i-plastic pick ukunqanda ukonakalisa i-grooves yokutywinwa.

3. Ukuhlolwa kweCandelo: Iikhrayitheriya eziPhambili zoTshintsho

Icandelo ngalinye elichithiweyo kufuneka lihlolwe ngokungqongqo ukuqinisekisa ukuba liyalungiswa okanye lifakwe endaweni yalo. Oku kulandelayo zizinto ezibalulekileyo zokuhlola kunye nemigangatho:

• Umgqomo wesilinda: Jonga udonga lwangaphakathi ukuba akukho mikrwelo, akukho mhlwa, okanye ukuguga. Sebenzisa i-surface tester yokulinganisa uburhabaxa-ukuba idlula i-Ra0.8 μm (umgangatho wemibhobho ye-hydraulic cylinder), umgqomo kufuneka utshintshwe. Kwimikrwelo emincinci (ubunzulu <0.2 mm), sebenzisa i-sandpaper ye-fine-grit (800-1200 mesh) ukupholisa ubuso kwicala le-cylinder axis, kodwa qinisekisa ukuba ububanzi bangaphakathi buhlala ngaphakathi kwinqanaba lokunyamezela (umzekelo, ± 0.05 mm kwi-barrel yangaphakathi ye-160 mm).
• I-Piston Rod: Jonga umphandle wangaphandle ukuba awunabo na izibonda, ukuxobuka kwechrome, okanye ukugoba. Sebenzisa isalathisi sokudayela ukulinganisa ukuchaneka-ukuba idigri yokugoba idlula i-0.5 mm ngemitha nganye, intonga kufuneka iqondiswe (usebenzisa umatshini wokulungisa i-hydraulic) okanye ithathelwe indawo. Qwalasela ubungqingqwa beplating ye-chrome kunye negeyiji yobukhulu bokugquma; ukuba ingaphantsi kwe-0.05 mm, yifake kwakhona intonga ukuthintela ukubola.
• Amatywina kunye ne-O-Rings: Jonga iintanda, ukuqina, okanye ukuguquka. Nokuba akukho monakalo ucacileyo, buyisela onke amatywina ngamatsha (njengoko amatywina ehla ngokuhamba kwexesha ngenxa yokuguga kweoyile kunye nokutshintsha kobushushu). Qinisekisa ukuba amatywina amatsha anobukhulu obufanayo kunye nezinto eziphathekayo njengezokuqala-umzekelo, sebenzisa izitywina ze-fluororubber kwiisilinda ezisebenza kwiindawo ezinobushushu obuphezulu (ngaphezu kwe-80 ° C) ukuxhathisa ukuguga kwe-thermal.
• Isikhokelo Sleeve kunye Piston: Khangela umngxuma wangaphakathi wesikhokelo sokugqoka-ukuba imvume phakathi komkhono wesikhokelo kunye nentonga yepiston idlula i-0.15 mm (ilinganiswe nge-fealer gauge), buyisela umkhono wesikhokelo. Hlola i-piston's sealing grooves ukwenzela ukuguqulwa; ukuba ubunzulu begroove buncitshiswe ngaphezu kwe-0.1 mm, buyisela ipiston ukuze uqinisekise ukuba isitywina silingana ngokuqinileyo.

4. Ukudityaniswa kwakhona: UkuSebenza okuchanekileyo ukuqinisekisa ukusebenza ngokutywinwa

1. Amacandelo acocekileyo: Ngaphambi kokuhlanganisana, hlambulula zonke iinxalenye (kubandakanywa i-cylinder barrel, i-piston rod, kunye nezitywina ezintsha) kunye ne-oil hydraulic oil cleaner (ugweme ukusebenzisa i-petroli okanye i-diesel, enokonakalisa izitywina). Yomisa amacandelo ngomoya ocinezelweyo (uxinzelelo <0.4 MPa) ukukhusela amanzi okanye intsalela ukuba ihlale.
2. Faka amatywina: Faka i-oyile encinci ye-hydraulic oil (uhlobo olufanayo neoli yenkqubo, umzekelo, i-ISO VG46) kwiimpawu ezintsha kwaye uzifake kwii-grooves ze-seal. Kwisitywina esiphambili (umzekelo, i-U-cup seal), qinisekisa ukuba umlomo ujongene necala loxinzelelo lweoli-ufakelo oluchanekileyo luya kubangela ukuvuza okukhulu. Sebenzisa isixhobo sokufakela isitywina (umkhono weplastiki) ukutyhala isitywina kwi-groove, ukuphepha ukujija.
3. Hlanganisa iPiston kunye nePiston Rod: Gcoba i-piston kwintonga ye-piston kwaye uqinise i-nut yokutshixa kwi-torque echaziweyo (umzekelo, i-250-300 N · m ye-M24 nuts). Sebenzisa i-torque wrench ukuqinisekisa ukunyanzeliswa, kwaye utshixe i-nut nge-cotter pin (ukuba ixhotyiswe) ukunqanda ukukhulula ngexesha lokusebenza.
4. Faka i-Piston Rod kwi-Cylinder Barrel: Faka ioli ye-hydraulic kwindawo yepiston yentonga kunye nodonga lwangaphakathi lwe-cylinder barrel. Tyhila intonga yepiston emgqomeni kancinci kwaye ngokuthe tye, uqinisekise ukuba ipiston ayingqubani nodonga lwangaphakathi lomgqomo. Emva koko, faka i-cap end end cap, ulungelelanise imingxuma ye-bolt, kwaye uqinise iibholithi kwipatheni ye-crisscross (i-torque kufuneka ihambelane neenkcukacha zomenzi-umzekelo, i-100 N · m ye-M18 bolts) ukuqinisekisa ukuba i-cap ivalwe ngokuqinileyo.
5. Qhagamshela imibhobho yeoli: Qhagamshela kwakhona i-oyile yokungena kunye nemibhobho yokuphuma ngokweelebhile ezenziwe ngexesha lokuqhaqha. Qinisa amakhonkco epayipi nge-torque wrench (umzekelo, 40-60 N · m kwimibhobho ye-intshi eyi-intshi) ukuze ugweme ukuqiniswa ngokugqithiseleyo, okungonakalisa intambo.

5. Uvavanyo lwasemva kokulungiswa: Qinisekisa ukuSebenza kunye noKhuseleko

Emva kokudibanisa kwakhona, yenza iimvavanyo ezibanzi zokuqinisekisa ukuba isilinda se-hydraulic sisebenza ngokuqhelekileyo:

• Akukho-Mthwalo uvavanyo: Qhagamshela ibhetri kwaye uqalise injini yelori. Yenza i-lever yokulawula i-boom yandise kwaye ihoxise i-cylinder ngamaxesha angama-5-10 ngesantya esiphantsi (10-15 mm / s). Qwalasela ukuvuza kwii-caps zokugqibela kunye ne-oil pipe joints-ukuba kukho ukuvuza, misa uvavanyo ngokukhawuleza kwaye ukhangele ukufakwa kwesitywina okanye i-torque ye-bolt.
• Uvavanyo lomthwalo: Sebenzisa i-gauge yoxinzelelo ukulinganisa uxinzelelo lwenkqubo ye-hydraulic ngexesha lokusebenza. Yandisa i-boom ukuya kubude bayo obuninzi kwaye usebenzise umthwalo (i-50% yomthwalo olinganisiweyo, umzekelo, iitoni ezili-10 ze-20-ton rated boom) imizuzu engama-30. Khangela ukuba i-cylinder ibambe umthwalo ngokuzinzileyo (akukho nto icacileyo 沉降) kwaye ukuba uxinzelelo luhlala ngaphakathi kwinqanaba elilinganisiweyo (umzekelo, i-25-30 MPa).
• Uvavanyo lokuSebenza: Vavanya isantya se-cylinder kunye nokuphendula ngokulungisa ukunyuswa kwe-boom kunye nokwandisa isantya. Qinisekisa ukuba ukunyakaza kuhamba kakuhle (akukho jitter okanye ingxolo) kwaye isantya sihambelana neenkcukacha zomenzi (umzekelo, 30-40 mm / s ukwandisa).

6. Iingcebiso zoLondolozo kunye noLondolozo lwasemva kokulungisa

Ukwandisa ubomi benkonzo ye-hydraulic cylinder elungisiweyo, landela la macebiso:

• Ukutshintsha kweOyile rhoqo: Faka endaweni yeoyile yolwelo olwenziwa ngamanzi rhoqo iiyure ezingama-2000 zokusebenza (okanye kanye ngonyaka, nokuba yeyiphi eza kuqala). Sebenzisa ioli ehlangabezana neemfuno zenkqubo (umzekelo, i-anti-wear hydraulic oil kunye ne-viscosity ye-ISO VG46) kunye nokucoca ioli nge-10 μm yokucoca ukususa ukungcola.
• Coca isihluzo soMoya: Isihluzo somoya se-hydraulic system sithintela uthuli ukuba lungene-lucoca rhoqo kwiiyure zokusebenza ze-500 kwaye luyibuyisele rhoqo kwiiyure ze-1000.
• Uhlolo Lwemihla Ngemihla: Phambi kokusetyenziswa ngakunye, jonga isilinda ukuba ayivuzi na, intonga yepiston yokukrweleka, kunye nenqanaba le-oyile kwitanki yolwelo olwenziwa ngamanzi. Ukuba ingxolo engaqhelekanga okanye intshukumo ecothayo ifunyenwe, yeka ukusebenza kwaye uhlole isilinda ngokukhawuleza.
