Ukuveliswa kwetywina lobuchwephesha lobuchwephesha be-yiwu inkampani enkulu yeemveliso zerabha
Iimpawu zoomatshini ezisebenza kulwelo oluphakathi ngokubanzi zixhomekeke kwifilimu engamanzi eyenziwe ngulwelo oluphakathi kwendawo yokuxubana yokuhamba kunye neeringi ezimileyo zokuthambisa. Ke ngoko, kufuneka kugcinwe ifilimu engamanzi phakathi kweendawo ezinobundlobongela ukuqinisekisa ukusebenza ngokuzinzileyo kwetywina lomatshini kunye nokwandisa ubomi bayo beenkonzo.
Ngokwemeko ezahlukeneyo, ukungqubana phakathi kwamakhonkco ashukumisayo kunye no-static wetywina loomatshini kuya kuba zezi zilandelayo:
(1) ukungqubana owomileyo:
Akukho manzi angena kumhlaba wokutyibilika okushenxayo, ke akukho bhanyabhanya ululwelo, kuphela uthuli, umaleko we-oxide kunye neemolekyuli zegesi ezi-adsorbed. Xa izangqa ezihambayo nezingashukumi zibaleka, umphumo kukuba umhlaba wokungqubana uya kushushu kwaye wonwabe, okukhokelela ekuvuza.
(2) ukuthambisa ajikeleze Boundary:
Xa uxinzelelo phakathi kweeringi ezihambayo nezimileyo zonyuka okanye ukubanakho kolwelo ukwenza ifilimu engamanzi kwindawo yokukhuhlana kubi, ulwelo luya kufakwa kumngxunya. Ngenxa yokuba umphezulu awucacanga ncam, kodwa awulingani, kukho unxibo oluqhakamshelweyo kwi-bulge, ngelixa ukusebenza kwe-lubrication kulwelo kugcinwa kwikhefu, kukhokelela kuthambiso lomda. Ukunxiba kunye nobushushu ukuthambisa ajikeleze imodareyitha.
(3) ukuthambisa ajikeleze Semi-ulwelo:
Kukho ulwelo emngxunyeni womphezulu wokutyibilika, kwaye ifilimu engamanzi ebhityileyo igcinwa phakathi komphezulu wonxibelelwano, ke ukufudumeza kunye nokunxiba iimeko zilungile. Ngenxa yokuba ifilimu engamanzi phakathi kweeringi ezihambayo nezimileyo inexinzelelo lomhlaba kwindawo yayo, ukuvuza kolwelo kulinganiselwe.
(4) Gcwalisa ukuthambisa ajikeleze:
Xa uxinzelelo phakathi kweeringi ezihambayo nezimileyo alonelanga, kwaye umsantsa uyanda, ifilimu engamanzi iyajiya, kwaye akukho nxibelelwano luqinileyo ngeli xesha, ke akukho nto yenzekayo. Nangona kunjalo, kule meko, umsantsa ophakathi kwendandatho yokuhamba kunye neringi emileyo mkhulu, ke ngoko uphawu lokutywina alunakufezekiswa kwaye ukuvuza kubi kakhulu. Olu hlobo lweemeko aluvunyelwanga kwisicelo esisebenzayo (ngaphandle kwetywina elisebenza ngomatshini wenwebu elawulwayo).
Uninzi lweemeko zokusebenza phakathi kweeringi ezinamandla nezimileyo zetywina elinomatshini zikwi-lubrication yomda kunye ne-semi-liquid lubrication, kunye ne-semi-liquid lubrication inokufumana eyona nto ifanelekileyo yokutywina phantsi kwemeko yobuninzi bokungqubana, oko kukuthi, ukunxiba okwaneleyo kunye nobushushu isizukulwana.
Ukwenza umsebenzi wetywina osebenza phantsi kweemeko ezifanelekileyo zokuthambisa, izinto ezinje ngeempawu eziphakathi, uxinzelelo, ubushushu kunye nesantya sokuhambisa kufuneka ziqwalaselwe ngokubanzi. Nangona kunjalo, ukukhetha uxinzelelo olufanelekileyo phakathi kweeringi ezihambayo nezingashukumiyo, ulwakhiwo lwe-lubrication efanelekileyo kunye nokuphucula umgangatho wobungqingqwa kumphezulu weeringi ezihambayo nezimileyo zizinto ezibalulekileyo zokuqinisekisa ukusebenza ngempumelelo kwetywina.
Izakhiwo ezininzi ukomeleza ukuthambisa ajikeleze
1.Buso ubuso bokugqibela:
Ngokubanzi amatywina oomatshini, embindini wesangqa esihambayo, embindini wesazisi esimileyo kunye nomgca osembindini weshafti konke kumgca othe tye. Ukuba isiphelo sobuso bezinye zeringi ehambayo okanye iringi emileyo yenziwe ukuba isuswe kumgca osembindini weshafti ngomgama othile, ulwelo lokuthambisa lunokuhanjiswa ngokuqhubekayo kumhlaba wokutyibilika xa iringi ijikelezisa ukuthambisa.
Kufuneka kuboniswe ukuba ubungakanani bokuqina akufuneki bube bukhulu kakhulu, ngakumbi kuxinzelelo oluphezulu, ukunyaniseka kuya kubangela uxinzelelo olungalinganiyo kwisiphelo sobuso kunye nokunxiba okungalinganiyo. Ukutywina ngesantya esiphezulu, ayicetyiswa into yokuba usebenzise isangqa eshukumayo njengeringi eccentric, ngapha koko umatshini uya kungcangcazela ngenxa yokulingana kwamandla e-centrifugal.
2.Ukubeka ubuso bokugqibela:
Kunzima koxinzelelo oluphezulu kunye noomatshini abasebenza ngesantya esiphezulu ukugcina ifilimu engamanzi phakathi kweendawo zokungqubana, ezihlala zitshatyalaliswa bubushushu bokukhuhlana obuveliswa luxinzelelo oluphezulu kunye nesantya esiphezulu. Kule meko, kuyasebenza kakhulu ukwamkela i-grooving ukomeleza ukuthambisa. Zombini iringi ehambayo kunye neringi emileyo inokutsalwa, edla ngokwenziwa ngezinto ezinokuthintela ukungahambelani. Isangqa esihambayo kunye nentsimbi emileyo akufuneki ifakwe ngexesha elinye, kuba oku kuya kunciphisa ukusebenza kokuthambisa. Ukuthintela ubumdaka okanye ukunxiba inkunkuma ekungeneni kumphezulu wobundlobongela kangangoko kunokwenzeka, kwaye ukutywina ulwelo oluhamba kwicala lamandla e-centrifugal (uhlobo lwe-outflow), indawo yokuvula kufuneka ivulwe kwindandatho emileyo ukuthintela ubumdaka ekubeni buziswe umphezulu wokungqubana ngamandla e-centrifugal. Ngokuchasene noko, xa ulwelo luhamba ngokuchasene namandla e-centrifugal (ukungena ngaphakathi), igroove kufuneka ivulwe kwindandatho ehambayo, kwaye amandla e-centrifugal aluncedo ekuphoseni ukungcola ngaphandle komhlaba.
Ii-grooves ezincinci kumphezulu wokungqubana zixande, zimile okwe-wedge, okanye ezinye iimilo. Igroove akufuneki ibengaphezulu kakhulu okanye ibe nzulu kakhulu, kungenjalo ukuvuza kuya kunyuka.
3.Static uxinzelelo ukuthambisa ajikeleze:
Oko kubizwa ngokuba yi-hydrostatic lubrication kukwazisa ngokuthe gca ulwelo lokucinezela olucinezelekileyo kumphezulu wokungqubana ukuthambisa ukuthambisa. Ulwelo olwenziweyo lokuthambisa lubonelelwa ngumthombo wolwelo owahlukileyo, ofana nempompo yesanti. Ngoluxinzelelo lokuthambisa lokucinezela, uxinzelelo lolwelo kumatshini luyachaswa. Le fomu ihlala ibizwa ngokuba yitywina loxinzelelo lwe-hydrostatic.
Amanyathelo kufuneka athathwe ukuseka ukuthambisa ifilimu ngerhasi ukutywina umatshini ophakathi wegesi, njengokumkela uxinzelelo lwegesi lokulawula itywina lomatshini okanye ukuthambisa okuqinileyo, oko kukuthi, ukusebenzisa izinto zokuthambisa njengeringi yentsimbi okanye iringi emileyo. Logama iimeko zivuma, imeko yegesi ephakathi kufuneka itshintshwe ibe kwimeko yolwelo ngokusemandleni, okulungele ukuthambisa kunye nokutywina.
