indlela yokukhetha umshini wokubumba umjovo

Kunezifanekiso ezimbili ku- umjovo udini umshini, omunye akanyakazi, ebizwa ngokuthi isifanekiso esilungisiwe; omunye anganyakaziswa, ebizwa ngokuthi isifanekiso esinyakazayo. Isikhunta sigxilwe ezifanekisweni ezimbili ngezikulufo namapuleti okucindezela ngokulandelana. Lapho kuvulwa isikhunta, isifanekiso esinyakazayo somshini wokubumba umjovo siyanyakaza, ngaleyo ndlela ukushayela isikhunta ukuvula.

Ngemva kwe isikhunta kukhiqizwa, kuyadingeka ukwenza umjovo wokubumba, faka umshini wokubumba umjovo, futhi uqale ukukhiqiza imikhiqizo. Noma kunjalo, kunamamodeli amaningi emishini yokubumba umjovo, futhi umshini ngamunye wokubumba umjovo unemingcele yawo. Isikhunta sokuklama kufanele sikwazi ukuhlangabezana nezidingo zemodeli yomshini wokubumba umjovo onikezwe ikhasimende, kungenjalo ngeke ikwazi ukukhiqiza. Ku

Kuningi design nemingcele womshini wokubumba umjovo. Okulandelayo kuzogxila kumapharamitha amaningana ahlobene nesikhunta. Ngithemba ukuthi abafundi bazonaka umklamo othize wesikhunta. Ku

1. Ivolumu yomjovo
Ivolumu yomjovo yinani eliphezulu lesisindo (noma inani levolumu) ukuthi umshini wokubumba umjovo ungadubula ngesikhathi esisodwa ngesikhathi sokukhiqiza, futhi imele umthamo omkhulu womjovo walolu hlobo lomshini wokubumba umjovo. Inani lokuncibilika elisetshenziswe esikhunjeni esiklanyelwe lingaphansi kwevolumu yomjovo womshini wokubumba umjovo. Kungenjalo, umkhiqizo awenelisekile futhi awukwazi ukukhiqizwa. Ku

2. Amandla okubamba
Okwenzekile kwaba amandla okucindezela omshini wokubumba umjovo esifanekiso lapho isikhunta sivalwa. Amandla okubamba adingekayo kumkhiqizo obunjiwe ngesikhathi sokubunjwa kumele abe ngaphansi kwamandla okubamba alinganiselwe omshini wokubumba okhethiwe.. Kungenjalo, ingcina encibilikisiwe izophuma kalula endaweni yokuhlukanisa, okuholela ekukhanyeni.

3. Ukuhlukanisa induku
Kunezinduku ezine zokubopha emakhoneni afile esifanekiso esilungisiwe kanye nesifanekiso esigudlukayo somshini wokubumba umjovo.. Umsebenzi wabo ukuqinisekisa ukuthi umshini wokubumba umjovo unamandla anele nokuqina, futhi ngesikhathi esifanayo unesibopho sesifanekiso esishelelayo. Noma kunjalo, ithambekele ekunciphiseni ubukhulu obuphelele besikhunta, ngoba isikhunta siphakanyiselwa phakathi kusukela phakathi kwenduku yokubopha ngesikhathi sokufakwa. Ku

Ubukhulu besikhunta abukwazi ukuba bukhulu kunebanga phakathi kwama-tie rods. Uma ubude besikhunta budlula ibanga phakathi kwezinduku zokubopha, hlola ukuthi isikhunta siphakanyiselwe endaweni yokusebenzela yezinduku ngokuzungezisa. Uma ukuphakanyiswa kwe-rotary akukwazi ukwenziwa, khona-ke usayizi wesikhunta ungashintshwa kuphela. , Noma shintsha umshini wokubumba umjovo. Ku

4. Ukuhlola usayizi weNozzle
Ikhanda lombhobho lomshini wokubumba umjovo ngokuvamile liyindilinga. Lapho ukhetha umkhono we-sprue, irediyasi eyindilinga yomkhono we-sprue kufanele ihambisane neradiyasi eyindilinga yombhobho. Ukuze uvimbele ukuncibilika kwengcindezi ephezulu ukuthi kungachichima kusuka kwigebe lokuxhumana phakathi kombhobho nomkhono we-sprue., irediyasi eyindilinga yomkhono we-sprue ngokuvamile kufanele ibe nkulu kunerediyasi yombhobho. Ngesikhathi esifanayo, usayizi wesiphetho esincane somgijimi oyinhloko kufanele futhi ube mkhulu kancane kunosayizi wembobo yombhobho. Kulula ukuvumelanisa i-muzzle

Ukuklanywa kwesistimu ye-gating yingxenye ebalulekile yokwakhiwa kwesikhunta sokujova. Inomthelela oqondile kumjikelezo wokubumba umjovo kanye nekhwalithi yezingxenye zepulasitiki (njengokubukeka, izakhiwo zomzimba, ukunemba kobukhulu, njll.).

Izimiso ezilandelayo kufanele zilandelwe lapho kuklanywa
(1) Isakhiwo somgodi kanye nendawo yokuvula isango kufanele kulingane ukuze kuvinjelwe isikhunta ukuthi singathwalwa umthwalo ongalingani futhi sibangele ukubanika..
(2) Ukuhlelwa kwemigodi namasango kufanele kunciphise ubukhulu besikhunta ngangokunokwenzeka.
(3) Ishaneli yokugeleza kwesistimu kufanele ibe mfushane ngangokunokwenzeka, kanye nosayizi we-cross-sectional kufanele ube ofanele (kuncane kakhulu, ukucindezela nokulahlekelwa ukushisa kuyoba kukhulu, futhi inkulu kakhulu, ukusetshenziswa kwepulasitiki kuzoba kukhulu); nciphisa ukugoba, futhi ukugoqana kwendawo kufanele kube kuncane ukwenza ukushisa nokulahlekelwa kwengcindezi Kube kuncane ngangokunokwenzeka.
(4) Okwemigodi eminingi, ukuncibilika kwepulasitiki kufanele kungene ekujuleni nasemakhoneni omgodi ngamunye ngesikhathi esifanayo ngangokunokwenzeka, leyo, abagijimi kufanele bahlelwe ngendlela elinganiselayo ngangokunokwenzeka
(5) Ngesisekelo sokuthi umgodi ugcwele, umthamo wesistimu yokuthulula kufanele ube mncane ngangokunokwenzeka ukuze unciphise ukusetshenziswa kwepulasitiki.
(6) Indawo yesango kufanele ifaneleke, zama ukugwema ukuthinta okufakiwe kanye nenkaba encane ukuze uvimbele umgogodla ukuthi ungaguquki. Izimpawu ezisele zesango akufanele zithinte ukubukeka kwengxenye yepulasitiki.

Izingozi ezinhlanu lokushisa eliphezulu kwe umjovo udini umshini
Izingozi ezinkulu ezinhlanu zokukhuphuka kwezinga lokushisa ngokweqile komshini wokubumba umjovo yilezi: deformation ezishisayo umshini, i-viscosity yamafutha encishisiwe, ukuguqulwa kwezimpawu zenjoloba, i-oxidation kawoyela ngesivinini kanye nokuwohloka, nokucindezela kwengxenye yomoya encishisiwe.

Enye yezingozi: deformation ezishisayo umshini
Izingxenye ezihambayo ezinama-coefficients ahlukene okwanda okushisayo ezingxenyeni ze-hydraulic zisabambekile ngenxa yokulingana kwazo okuncane., okubangela ukungasebenzi kahle, okuthinta ukunemba kokudluliselwa kwesistimu ye-hydraulic, kanye nokuwohloka kwekhwalithi yokusebenza kwezingxenye.

Ukulimaza okubili: ukunciphisa i-viscosity yamafutha
Ukukhuphuka kwezinga lokushisa okweqile komshini wokubumba umjovo kuzobangela ukuba i-viscosity yamafutha yehle, ukwandisa ukuvuza, kanye nokusebenza kahle kwe-volumetric yepompo kanye nokusebenza kahle kwalo lonke uhlelo kuzoncishiswa kakhulu. Njengoba i-viscosity yamafutha iyancipha, ifilimu yamafutha ye-valve eshelelayo nezinye izingxenye ezihambayo ziba mncane futhi zinqunywe, futhi ukumelana nokungqubuzana kuyanda, okuholela ekwandeni kokuguga.

Ingozi 3: Ukuguqulwa kwezimpawu zenjoloba
Ukukhuphuka kwezinga lokushisa okweqile komshini wokubumba umjovo kuzokhubaza izimpawu zenjoloba, ukusheshisa ukwehluleka ukuguga, ukunciphisa ukusebenza kokuvala nempilo yesevisi, futhi kubangele ukuvuza.

Ingozi 4: Sheshisa i-oxidation kanye nokuwohloka kwamafutha
Ukukhuphuka kwezinga lokushisa okweqile komshini wokubumba umjovo kuzosheshisa i-oxidation kanye nokuwohloka kwamafutha., nciphisa izinto ze-bituminous, futhi unciphise impilo yesevisi kawoyela we-hydraulic. I-precipitates ivimba i-orifice emanzi kanye nembobo ye-valve ehlukanisiwe, okwenza i-valve yokucindezela ibambelele futhi ingakwazi ukunyakaza, futhi ipayipi lensimbi leluliwe futhi ligobile, noma yagqabuka.

Ingozi 5: Okuholela ekusebenzeni okungekuhle kwezingxenye
Ukwenyuka kwezinga lokushisa okweqile kwe umjovo udini umshini kuzoholela ekusebenzeni okungekuhle kwezingxenye, futhi umoya oncibilikisiwe emafutheni uzophuma, okuholela emaphaketheni omoya, okuzonciphisa ukusebenza komsebenzi we-hydraulic system. Izinga lokushisa elifanele le-hydraulic system kufanele libe phakathi 45 amadigri kanye 50 amadigri. Isizathu siwukuthi uhlelo lwe-hydraulic luklanyelwe ngokusho kwe-viscosity yamafutha okucindezela okukhethiwe, kodwa i-viscosity izoshintsha ngokushisa kwamafutha, okuzothinta umsebenzi ohlelweni. Izingxenye, njengamasilinda amafutha, ama-valve we-hydraulic, njll., nciphisa ukunemba kokulawula kanye nokuzwela kokuphendula, ikakhulukazi imishini yokujova ngokunemba.

Ngesikhathi esifanayo, uma i izinga lokushisa iphakeme kakhulu, izosheshisa ukuguga kophawu futhi ibangele ukuba lukhuni futhi iqhekeke; uma izinga lokushisa liphansi kakhulu, amandla okucubungula azosetshenziswa futhi isivinini sokusebenza sizoncishiswa. Ngakho-ke, kudingekile ukunaka kakhulu izinga lokushisa elisebenzayo lamafutha we-hydraulic. Kunezizathu eziningi zokushisa kwamafutha aphezulu, kodwa eziningi zazo zibangelwa ukwehluleka kwesifunda samafutha noma ukwehluleka kwesistimu yokupholisa.

Uma unemibuzo ku umjovo udini ,plz ngicela ukubuza Iqembu le-FLYSE,sizokunikeza isevisi engcono kakhulu!
