ukuhlolwa okubonakalayo
Kwamanye amaphutha alula, izingxenye nezingxenye zingahlolwa ngokubona, imodeli yesandla, ukuzwa nokuhogela. Ukulungisa noma ukushintsha izesekeli; bamba ipayipi lamafutha (ikakhulukazi ipayipi lerabha) ngesandla, lapho kunamafutha okucindezela agelezayo, kuyoba nomuzwa wokudlidliza, kodwa ngeke kube khona into enjalo lapho kungabikho ukugeleza kwamafutha noma ukucindezela kuphansi kakhulu.
Ngaphezu kwalokho, ukuthinta ngesandla kungasetshenziswa futhi ukwahlulela ukuthi ukugcotshwa kwezingxenye ze-hydraulic ezinezingxenye zokuhambisa ngomshini kuhle yini. Izwa ukushintsha kwezinga lokushisa kwegobolondo lengxenye ngezandla zakho. Uma igobolondo lesakhi lishiswa ngokweqile, kusho ukuthi ukugcotshwa kubi; ukulalela kungahlulela izingxenye zemishini Iphoyinti lephutha kanye nedigri yokulimala okudalwe umonakalo, njengokumuncwa kwepompo ye-hydraulic, ukuvulwa kwevalvu echichimayo, ukukhishwa kwezingxenye zekhadi kanye namanye amaphutha kuzokwenza imisindo engavamile njengokushayisana kwamanzi noma “isando samanzi”; ezinye izingxenye zizolimala ngenxa yokushisa ngokweqile, ukugcoba okungalungile kanye ne-cavitation. Uma kukhona iphunga elingavamile ngenxa yezinye izizathu, iphuzu lephutha lingahlulelwa ngokuhogela.
ukushintshanisa ukuxilonga
Uma lingekho ithuluzi lokuxilonga endaweni yokulungisa noma izingxenye ezizohlolwa zinembe kakhulu ukuba zingahlakazwa, le ndlela kufanele isetshenziselwe ukususa izakhi okusolakala ukuthi zinephutha futhi esikhundleni sazo kufakwe ezintsha noma izingxenye zemodeli efanayo esebenzayo. ngokuvamile kweminye imishini yokuhlola. Ukuxilongwa kungenziwa uma iphutha lingaqedwa.
Kungase kube nzima ukuhlola iphutha ngendlela yokuxilongwa yokubuyisela, nakuba kunqunyelwe isakhiwo, ukugcinwa kwengxenye yendawo noma ukuhlakazeka okungahambi kahle, njll., kodwa kuma-valve amancane futhi asebenziseka kalula njengama-balance valves, ukuchichima. ama-valve, nama-valve endlela eyodwa Kulula kakhulu ukusebenzisa le ndlela ukuqaqa izingxenye. Indlela yokuxilonga esikhundleni ingagwema ukuwohloka kokusebenza kwezingxenye ze-hydraulic ezibangelwa ukuhlakazeka okuyimpumputhe. Uma amaphutha ashiwo ngenhla engahlolisiswa indlela yokubuyisela, kodwa i-valve yokuphepha eyinhloko esolisayo ikhishwa ngokuqondile futhi ihlakazwe, uma ingekho inkinga ngengxenye, ukusebenza kwayo kungase kuthinteke ngemva kokufakwa kabusha.
Indlela yokuhlola ukulinganisa imitha
Ukwahlulela iphuzu lephutha lesistimu ngokulinganisa ingcindezi, ukugeleza kanye nezinga lokushisa likawoyela lamafutha we-hydraulic engxenyeni ngayinye yesistimu ye-hydraulic. Kunzima kakhulu, futhi ubukhulu bokugeleza bungahlulelwa kuphela ngesivinini sesenzo se-actuator. Ngakho-ke, ekutholeni indawo, izindlela eziningi zokuthola ingcindezi yesistimu zisetshenziswa.
Ukwehluleka, okuvame kakhulu ukulahlekelwa kwe-hydraulic pressure. Uma kutholakala ukuthi kuyinkinga ye-hydraulic cylinder, ingaphinde icutshungulwe:
Ngokuvamile, ukuvuza kwamasilinda we-hydraulic kuhlukaniswe izinhlobo ezimbili: ukuvuza kwangaphakathi nokuvuza kwangaphandle. Uma nje sibheka ngokucophelela, singakwazi ukwahlulela imbangela yokuvuza kwangaphandle. Kunzima kakhulu ukwahlulela imbangela yokuvuza kwangaphakathi kwe-hydraulic cylinder, ngoba asikwazi ukubona ngokuqondile ukuvuza kwangaphakathi.
Okukodwa, ukuvuza kwangaphandle.
1. Ukulimala kwe-seal phakathi komkhawulo onwetshiwe we-piston rod kanye ne-piston rod ikakhulukazi ubangelwa ukuqina kwe-cylinder ye-piston, futhi kubangelwa ukuguga.
2. Isigxivizo esiphakathi komkhawulo onwebekayo we-piston rod kanye ne-cylinder liner sonakalisiwe. Lokhu kubangelwa kakhulu ukuguga kophawu ngemva kokusetshenziswa isikhathi eside. Kukhona futhi izimo eziningi lapho uphawu lucindezelwa futhi lonakaliswe amandla amakhulu lapho kusetshenziswa isembozo esiphezulu. Kukhona futhi amasilinda amaningi asebenza nge-hydraulic akhiqizwa eChina. Idizayini yomkhiqizi ayinangqondo, futhi ezimweni eziningi, umenzi ungonga izindleko.
3. Ukuqhekeka kwamajoyinti epayipi likawoyela elingenayo nephumayo lesilinda kawoyela nakho kuzodala ukuvuza kwesilinda sikawoyela osebenza ngehydraulic.
4. Ukuvuza kukawoyela okubangelwa ukukhubazeka kusilinda block noma ikhava yesilinda ekugcineni.
5. I-piston rod iyadonswa futhi inemigodi, imigodi, njll.
6. Ukuwohloka kwamafutha okugcoba kwenza izinga lokushisa le-cylinder yamafutha likhuphuke ngendlela engavamile, okukhuthaza ukuguga kwendandatho yokuvala.
7. Ukuvuza kukawoyela okubangelwa ukusetshenziswa njalo ngale kwebanga lokucindezela kwesilinda.
Okubili, ukuvuza kwangaphakathi.
1. Indandatho ekwazi ukumelana nokugqokwa ku-piston igqokwa kakhulu, idala ukungqubuzana phakathi kwepiston ne-cylinder liner, futhi ekugcineni ihlunga i-cylinder liner, piston kanye ne-seal.
2. Uphawu luyehluleka ngemva kokusetshenziswa isikhathi eside, futhi uphawu lwe-piston (ikakhulukazi u-U, V, Y-rings, njll.) luyaguga.
3. Amafutha we-hydraulic angcolile, futhi inani elikhulu lokungcola lingena ku-cylinder futhi ligqoke uphawu lwe-piston kuze kube seqophelweni lokulimala, ngokuvamile ukufakwa kwensimbi noma ezinye izinto zangaphandle.
3. Izindaba ezidinga ukunakwa ekusetshenzisweni kwamasilinda amanzi.
1. Ngesikhathi sokusetshenziswa okuvamile, kufanele sinake ukuvikela indawo yangaphandle yenduku ye-piston ukuvimbela ukulimala kophawu kusuka kuma-bumps kanye nemihuzuko. Manje amanye amasilinda emishini yokwakha aklanywe ngamapuleti okuzivikela. Nakuba ekhona, sisadinga ukunaka ukuvimbela amaqhubu nokuklwebheka. ngiklwebhekile. Ngaphezu kwalokho, ngidinga futhi ukuhlanza njalo udaka nesihlabathi esiyingini esinamandla sokuvikela uthuli yesilinda kanye nenduku yepiston eveziwe ukuvimbela ukungcola okunzima ukukuhlanza okunamathiselwe ebusweni be-piston rod ukuthi kungangeni ngaphakathi. yesilinda, okuzokwenza ukuthi ipiston, isilinda noma uphawu kulimaze. umonakalo.
2. Ngesikhathi sokusetshenziswa okuvamile, kufanele futhi sinake ukuhlola njalo izingxenye zokuxhuma njengezintambo namabhawudi, futhi sizibophe ngokushesha uma zitholakala zikhululekile. Ngoba ukuxega kwalezi zindawo kuzodala nokuvuza kukawoyela we-hydraulic cylinder, okuqondwa kahle yilabo abenza imishini yokwakha.
3. Gcoba njalo izingxenye zokuxhuma ukuze uvimbele ukugqwala noma ukuguga okungavamile esimweni esingenawo uwoyela. Kudingeka futhi sinake. Ikakhulukazi kwezinye izingxenye ezinokugqwala, kufanele sibhekane nazo kusenesikhathi ukuze sigweme ukuvuza kwamafutha amasilinda amanzi okubangelwa ukugqwala.
4. Ngesikhathi sokugcinwa okujwayelekile, kufanele sinake ukuguqulwa okujwayelekile kwamafutha we-hydraulic kanye nokuhlanza okufika ngesikhathi kwesihlungi sesistimu ukuze kuqinisekiswe ukuhlanzeka kwamafutha we-hydraulic, okubaluleke kakhulu futhi ekwandiseni impilo yesevisi yama-cylinder hydraulic.
5. Ngesikhathi somsebenzi ojwayelekile, kufanele sinake ukulawula izinga lokushisa lesistimu, ngoba izinga lokushisa eliphezulu kakhulu likawoyela lizonciphisa impilo yesevisi ye-seal, futhi izinga lokushisa eliphezulu likawoyela lesikhathi eside lizobangela ukuguqulwa okuhlala njalo kwe-seal, futhi ezimweni ezimbi kakhulu, uphawu luyohluleka.
6. Ngokuvamile, ngaso sonke isikhathi lapho siyisebenzisa, sidinga ukuqhuba isilingo sokunwetshwa okuphelele nokuhoxiswa okugcwele kwemivimbo engu-3-5 ngaphambi kokusebenza. Inhloso yokwenza lokhu ukukhipha umoya ohlelweni bese ushisa kuqala uhlelo ngalunye, ukuze ugweme ngokuphumelelayo ukuba khona komoya noma amanzi ohlelweni, okubangela ukuqhuma kwegesi emzimbeni we-cylinder, okuzolimaza izimpawu futhi kubangele ukuvuza kwangaphakathi. yesilinda, njll. Iphutha.
7. Ngemva kokuba umsebenzi ngamunye usuqediwe, sidinga ukunaka ukugcina izingalo namabhakede amakhulu nezincane zisesimweni esifanele, okungukuthi, ukuqinisekisa ukuthi wonke uwoyela we-hydraulic ku-hydraulic cylinder ubuyiselwa ethangini likawoyela we-hydraulic ukuze kuqinisekiswe. ukuthi i-hydraulic cylinder ayikho ngaphansi kwengcindezi. Ngenxa yokuthi i-hydraulic cylinder ingaphansi kwengcindezi ohlangothini olulodwa isikhathi eside, izophinde ibangele ukulimala uphawu.
