Izimpawu zemishini

Usizo lwabenza imisenenzi mechnical uphawu umkhiqizi yiwu inkampani enkulu uphawu iraba imikhiqizo

Izimpawu zemishini ezisebenza endaweni enamanzi ngokuvamile zithembele kwifilimu ewuketshezi eyenziwe nguketshezi olumanzi phakathi kwezindawo zokungqubuzana kwezindandatho ezihambayo nezimile zokuthambisa. Ngakho-ke, kuyadingeka ukugcina ifilimu ewuketshezi phakathi kwezindawo eziqubuzanayo ukuqinisekisa ukusebenza okuzinzile kophawu lomshini nokwandisa impilo yenkonzo yayo.

Ngokuya ngezimo ezahlukahlukene, ukungqubuzana phakathi kwamasongo ashukumisayo nasesimweni sokuqina kwemishini kuzoba ngale ndlela elandelayo:

(1) ukungqubuzana owomile:

Akukho uketshezi olungena endaweni yokushayisana okushibilikayo, ngakho-ke ayikho ifilimu ewuketshezi, uthuli kuphela, ungqimba lwe-oxide nama-molecule egesi anezikhangiso. Lapho izindandatho ezihambayo nezimile zisebenza, umphumela uba ukuthi indawo yokushayisana izoshisa futhi iguge, okuholele ekuvuza.

(2) Ukuthambisa kwemingcele:

Lapho ingcindezi phakathi kwezindandatho ezihambayo nezimile inyuka noma ikhono loketshezi lokwakha ifilimu eliwuketshezi endaweni engqubuzanayo lincane, uketshezi luzokhishwa esikhaleni. Ngoba ingaphezulu alilele ngokuphelele, kodwa alilingani, kunokugqoka okuxhumene ku-bulge, kuyilapho ukusebenza kokuthambisa kuketshezi kugcinwa ekhefini, okuholela ekuthambekeni kwemingcele. Ukugqoka nokushisa kokuthambisa kwemingcele kulinganiselwe.

(3) ukuthambisa Semi-liquid:

Kukhona uketshezi emgodini wobuso obushibilikayo, futhi kugcinwa ifilimu elincanyana eliwuketshezi phakathi kwezindawo zokuxhumana, ngakho-ke izimo zokushisa nokugqoka zilungile. Ngoba ifilimu ewuketshezi phakathi kwezindandatho ezihambayo nezimile inokuphakama komhlaba endaweni yayo, ukuvuza koketshezi kunqunyelwe.

(4) Qedela ukuthambisa uketshezi:

Lapho ingcindezi phakathi kwamasongo ahambayo nayi-static inganele, futhi igebe liyanda, ifilimu ewuketshezi iyajiya, futhi akukho ukuxhumana okuqinile ngalesi sikhathi, ngakho-ke akukho mkhuba wokungqubuzana. Kodwa-ke, kuleli cala, igebe phakathi kwendandatho ehambayo nendandatho emile likhulu, ngakho-ke umphumela wokufaka uphawu awutholakali futhi ukuvuza kubi kakhulu. Lolu hlobo lwesimo ngokuvamile aluvunyelwe ekusetshenzisweni okungokoqobo (ngaphandle kophawu lomshini we-membrane elawulwayo).

Iningi lezimo zokusebenza phakathi kwezindandatho eziguqukayo nezimile zensimbi yomshini zikuthambiso lwemingcele kanye nokugcotshwa okuwuketshezi oluncane, futhi ukuthambisa okungamanzi oketshezi kungathola umphumela omuhle kakhulu wokubeka uphawu ngaphansi kwesimo senani eliphansi lokungqubuzana, okungukuthi, ukugqoka nokushisa okwenelisayo isizukulwane.

Ukuze wenze uphawu lwe-mechanical lusebenze ngaphansi kwezimo ezinhle zokuthambisa, izinto ezinjengezici eziphakathi, ingcindezi, izinga lokushisa nesivinini sokuhambisa kufanele kubhekwe ngokuphelele. Kodwa-ke, ukukhetha ingcindezi efanelekile phakathi kwezindandatho ezihambayo nezingaguquguquki, ukwakheka kokuthambisa okunengqondo nokwenza ngcono ikhwalithi yendawo yokushayisana kwamasongo ahambayo nawokuma okumile nakho kuyizinto ezibalulekile zokuqinisekisa ukusebenza ngempumelelo kophawu.

Izakhiwo eziningana zokuqinisa i-lubrication

1.Qeda ubuso ukweqa:

Ngokuvamile izimpawu zemishini, maphakathi nendandatho ehambayo, maphakathi nendandatho emile nolayini ophakathi nendawo kushaft konke kulayini oqondile. Uma isikhungo sobuso bokugcina kwenye yezindandatho ezihambayo noma iringi emile yenziwa ukuthi isuswe emgqeni osenkabeni weshaft ngebanga elithile, uketshezi oluthambisa lungalethwa ngokuqhubekayo endaweni eshibilikayo lapho indandatho ijikeleza ukuthambisa.

Kumele kuvezwe ukuthi ubukhulu bokuqina akumele bube bukhulu kakhulu, ikakhulukazi ekucindezelweni okuphezulu, ukwehluka kuzodala ingcindezi engalingani ebusweni bokugcina nokugqoka okungalingani. Okwezimpawu ezinesivinini esikhulu, akukhuthazwa ukuthi usebenzise iringi ehambayo njengeringi eccentric, ngaphandle kwalokho umshini uzodlidliza ngenxa yebhalansi yamandla we-centrifugal.

2.Ukuhlela ubuso bokugcina:

Kunzima ukuthi imishini yengcindezi ephezulu nejubane igcine ifilimu ewuketshezi phakathi kwezindawo ezinokungqubuzana, okuvamise ukubhujiswa ukushisa kokungqubuzana okudalwa wumfutho ophakeme nesivinini esikhulu. Kulokhu, kuyasebenza kakhulu ukwamukela i-grooving ukuqinisa ukuthambisa. Kokubili iringi ehambayo nendandatho emile ingabekwa, okuvame ukwenziwa ngezinto ezingagqoki. Iringi ehambayo nendandatho emile akufanele ifakwe ngesikhathi esisodwa, ngoba lokhu kuzonciphisa umphumela wokuthambisa. Ukuze uvikele ukungcola noma ukugqoka imfucumfucu ekungeneni endaweni yokushayisana ngangokunokwenzeka, futhi ukuvala uketshezi olugeleza ku-centrifugal force direction (uhlobo lwe-outflow), inkatho kufanele ivulwe eringini le-static ukugwema ukungcola ekungenisweni indawo yokushayisana ngamandla we-centrifugal. Ngokuphambene nalokho, lapho uketshezi lugeleza ngamandla we-centrifugal (ukugeleza kwangaphakathi), inkatho kufanele ivulwe eringini elihambayo, futhi amandla we-centrifugal ayasiza ukukhipha ukungcola emseleni.

Ama-grooves amancane ebusweni bokungqubuzana angunxande, amise okwekhanda, noma obunye ubujamo. IGroove akufanele ibe yinde kakhulu noma ijule kakhulu, ngaphandle kwalokho ukuvuza kuzokwanda.

3.Static ingcindezi Lubrication:

Okubizwa nge-hydrostatic lubrication ukwethula ngqo uketshezi oluthambile lokucindezela endaweni yokushayisana yokuthambisa. I-lubricating liquid eyethulwe ihlinzekwa ngumthombo oketshezi ohlukile, njengephampu ye-hydraulic. Ngalolu ketshezi olucindezelayo lokuthambisa, ingcindezi yoketshezi esemshinini iyaphikiswa. Leli fomu livame ukubizwa ngokuthi yi-hydrostatic pressure seal.

Izinyathelo kufanele zithathwe ukusungula ukuthambisa igesi kwefilimu ngomshini wegesi ophakathi, njengokusebenzisa i-static pressure elawulwa ifilimu mechanical seal noma i-lubrication eqinile, okusho ukuthi, ukusebenzisa okokuzigcoba njengendandatho elawula noma indandatho emile. Uma nje izimo zivuma, isimo segesi esiphakathi nendawo kufanele siguqulwe sibe isimo esimaphakathi samanzi ngangokunokwenzeka, esivumelana nokuthambisa nokuvala uphawu.
