Iindaba ezigqwesileyo, gcina i-500,000 RMB intlawulo yokutshintsha ioyile emva kokususa i-oyile yokuthambisa iVarnish

Okugqwesileyo, gcina i-500,000 RMB intlawulo yokutshintsha ioyile emva kokususa i-oyile yokuthambisa iVarnish

Ngokweenkcukacha-manani zophononongo,

I-80% yokusilela kwezixhobo ezijikelezayo kubangelwa kungcoliseko lwe-lubricant,

Ngeli xesha, utshintsho lweoyile lulonke yinkcitho enkulu yezixhobo,

Kwaye kwandisa ukukhutshwa kwekhabhoni,

Kwanokuba ioli iyatshintshwa, ayinakuzicombulula iingxaki ezinjengongcoliseko kwinkqubo yeoli yokuthambisa.

Ukuba imeko yokuwohloka kwenkqubo ayinakusonjululwa ngeoyile entsha,

Imingcipheko yokusebenza ngokukhuselekileyo ngenxa yokuwohloka kokusebenza kweoyile,

Kufuneka isombulule ingxaki yokonakala kweoyile!

Ukhuseleko lwendalo esingqongileyo eWinsonda lusebenza ngokukhethekileyo kwiinkonzo zolawulo longcoliseko lweoyile kwimizi-mveliso, enokuphunyezwa kumashishini:

1）Yonga kwiindleko zokuthenga ioyile entsha

2) Akukho sidingo sokuyeka ukutshintsha ioyile, ukunciphisa ilahleko yokuvala

3) Ukunciphisa izinga lokungaphumeleli kwezixhobo kunye nokuphucula ukusebenza kakuhle kwemveliso

4) Ukunciphisa iindleko zokulahlwa kwenkunkuma enobungozi kunye nongcoliseko lokusingqongileyo

Imeko eqhelekileyo yeWinsonda kulawulo longcoliseko lweoyile kwimizi mveliso

Iprofayile yeprojekthi

Umxhasi lishishini elidibeneyo elityalwe ngokudibeneyo ziinkampani zaseTshayina Fortune 500 kunye neyona nkampani inkulu yeekhemikhali kwihlabathi.I-compressor yegesi eqhekekileyo kunye ne-injini ye-steam ye-100 kt / isebe lemveliso ye-ethylene zizixhobo ze-Mitsubishi Heavy Industries Corporation yase-Japan.Ukusukela oko yaqalayo iyunithi yokucinezela ngo-Agasti 5, 2020, iqondo lobushushu le-injini yomphunga ethwele i-TI31061B liye laguquguquka rhoqo, kwaye liya lisanda.NgoDisemba 14,2020,16:43TI31061B ifikelele kwi-118℃, kuphela i-2℃ kude nexabiso le-alam.Iqondo lokushisa liphezulu kakhulu, eliya kulimaza i-bearing pasteurized alloy, ebangela i-tile evuthayo okanye ukuguquguquka kwexesha elide lobushushu, ukubethelwa kwe-vibration kunobundlobongela, kubangela umonakalo wokuthwala, kwaye ekugqibeleni umonakalo kwiyunithi.

02 Uhlalutyo lwesizathu kunye namanyathelo onyango

2.1 Unobangela wokuguquguquka kweqondo lobushushu kwithrust yeinjini yomphunga ene-TI31061B

Emva kophando kunye nohlalutyo lwentsingiselo yokuguquguquka kobushushu be-injini yomphunga etyhalela i-TI31061B, ngaphandle kweengxaki zokubonisa isixhobo sangaphandle, ukuguquguquka kwenkqubo, ukunxitywa kwebrashi ye-injini yomphunga, ukuguquguquka kwesantya sesixhobo, umgangatho wezixhobo, njl. njl., izizathu zokuguquguquka kobushushu beshaft ziyahlaziywa ngolu hlobo lulandelayo: ((1) I-oyile yokuthambisa esetyenziswa kwicompressor yimineral oil.Xa iqondo lokushisa liphezulu, ioli yokuthambisa i-oxidized, kwaye iimveliso ze-oxidation ziqokelelana kumphezulu we-shafts ukwenza ivanishi. , ngoko ke inkqubo ihamba kunye nokukhawuleza kwe-oxidation reaction.Izinga le-oxidation kwindawo ethwele ithrust inokuba phezulu ngokuphindwe kaninzi kunezinye iisayithi.Kule nkqubo, iimveliso ze-oxidation ziya kubakho kwimeko yokunyibilika kwaye ziya kuphuma xa zihluthi.Ioli yokuthambisa yenza i-varnish e-soluble kwindawo yokushisa ephezulu kunye noxinzelelo oluphezulu.Kwinkqubo yokuhamba ukusuka kwindawo yokushisa ephezulu ukuya kwindawo yeqondo lokushisa eliphantsi, ukuhla kweqondo lokushisa kukhokelela ekunciphiseni kwe-solubility, kunye neengqungquthela ze-varnish zinyuka kwi-oyile yokuthambisa kwaye ziqale ukufaka.Iincinci ze-varnish ziqala ukudibanisa kwaye zenze i-sediment, kwaye ziza kufakwa ngokukhethiweyo kwindawo eshushu yensimbi.Ngelo xesha, ngenxa yokuba ukushisa kwe-thrust bear kuphezulu ukususela ekuqaleni kokwakhiwa, i-bearing bush iqondo lokushisa apha likhuphuka ngokukhawuleza kwaye ubushushu bezinye iibheringi buguquka kancinci.

2.2 Sombulula ingxaki yethrust yeinjini yomphunga ene-TI31061B

(1) Emva kokufumanisa ukuba ubushushu be-thrust ethwele i-T31061B bunyuka ngokucothayo, ubushushu be-oyile yokuthambisa yehliswa ukusuka kwi-40.5 ℃ ukuya kwi-38℃ kunye noxinzelelo lweoyile yokuthambisa yonyuswe ukusuka kwi-0. 15MPa ukuya kwi-0.176MPa ukunciphisa umkhwa wokunyuka kancinci ubushushu behlathi le-shaft.

(2) Yandisa icala loxinzelelo oluphantsi umthwalo we-injini yomphunga, nyusa icala loxinzelelo oluphezulu, nciphisa i-axial thrust ye-thrust bearing, ukuze ucuthe isantya esinyukayo sobushushu be-thrust. (Jonga uMfanekiso 1)

Umzobo 1: Nge-15, 2020 kaNovemba, isithando somlilo esi-2 # esiqhekezayo sanqunyulwa, sinciphisa umthwalo malunga neetoni ezingama-50 ukuya kwiitoni ezingama-279, kunye nejika lokutshintsha kobushushu.

(3) NgoNovemba 23, 2020, isampuli yokuvelisa ioli ye-lubricating yeyunithi yathunyelwa kumntu wesithathu ukuze kuhlolwe kwaye kuhlalutywe.Iziphumo eziboniswe kuMfanekiso 2 zibonisa ukuba ixabiso le-MPC liphezulu, elinokugqiba ukuba ivanishi eveliswe yi-oyile oxidation yenye yezizathu zobushushu obuphezulu be-steam turbine thrust ethwele i-T31061B.Xa kukho i-varnish kwi-oyile yokuthambisa, ngenxa yokuba amandla okutshatyalaliswa kweoli yokugcoba kwi-varnish particles iyancipha, ukuchithwa kunye nemvula yeengqungquthela ze-varnish kwi-oyile yinkqubo ye-balance balance.Xa i-saturation state ifikelelwe, i-varnish iya kuxhoma kwi-bearing okanye i-shafting, ibangele ukuguquguquka kweqondo lokushisa kwe-shafting, ukuzisa iingozi ezinkulu ezifihliweyo ekusebenzeni okukhuselekileyo.Ngophando lwabathengi bakhetha umphumo wokusetyenziswa kunye nodumo oluhle lwemarike ye-Kunshan Winsonda ukukhuselwa kwendalo. Ukuveliswa kwe-WVD yochungechunge lwe-electrostatic adsorption + i-resin adsorption ikhompawundi yokususa i-oyile yokucoca ivanishi..

Umzobo 2: Iziphumo zovavanyo kunye nohlalutyo emva kokufakwa kwe-varnish yokucoca ioli

ivanishi yimveliso yokuthotywa kwe-oyile, phantsi kweemeko ezithile zeekhemikhali kunye nobushushu, ukunyibilika okanye ukunqunyanyiswa kwe-oyile.Xa i-sludge idlula iqondo lokuchithwa kweoli yokuthambisa, i-sludge iya kukhupha phezu kwendawo yokwenza i-varnish.

I-WVD-II yokususa i-oyile yokucoca ivanishi idibanisa ngokufanelekileyo itekhnoloji yokucoca i-electrostatic adsorption kunye netekhnoloji yokutshintshiselana nge-ion, enokususa ngokufanelekileyo kwaye ithintele udaka lweoyile olunyibilikayo nolunganyibilikiyo oluveliswe kwinkqubo eqhelekileyo yokusebenza kweinjini yomphunga, ukuze ivanishi ingakwazi iveliswe.

Injongo ye-WVD-II kukuphelisa izinto zokubunjwa kwe-varnish.Le teknoloji inokunciphisa umxholo wodaka lweoyile ngexesha elifutshane, kwaye yenze inkqubo yokuthambisa iqulethe udaka oluninzi lwe-oyile / ivanishi ukuze ibuyisele imeko yokusebenza ngeentsuku ezimbalwa, ukuze isombulule ngokupheleleyo ingxaki yokunyuka kancinci iqondo lobushushu elibangelwa yivanishi.

Umzobo 3: Iifoto ze-WVD-II i-varnish yokucoca i-oyile yokucoca kwindawo yabathengi

2.3 WVD-IIivanishi isicoci seoli ivanishiisiphumo

I-WVD-II ivanishi yokususa i-oyile yokucoca yafakelwe yaza yasetyenziswa ngoDisemba 14,2020, kwaye iqondo lobushushu le-injini yomoya etyhalela i-TI31061B lehle laya kutsho malunga ne-95℃ ngo-Disemba 19,2020 (jonga uMfanekiso 4).

Umzobo 4: Intsingiselo yobushushu ye-injini yomphunga etyhalela i-TI31061B

Emva kwenyanga enye yokusebenza komatshini wokucoca ioyile, umgangatho weoyile yokuthambisa yeyunithi uphuculwe kakhulu.Ngokubona isampuli kunye nokuhlalutya, isalathisi sokuthambekela kwe-varnish yeoli iyancitshiswa ukusuka kwi-10.2 ukuya kwi-4.2, kwaye inqanaba lokungcola liyancipha ukusuka> 12 ukuya kwinqanaba 5. Akukho kulahleka kweyiphi na isongezo kwioli yokuthambisa (jonga umfanekiso 5)

Umzobo 5: Ukufumanisa kunye nokuhlalutya iziphumo emva kokufaka i-WVD-II

03 WVD-IIivanishi yokucoca ioli yokucocaukunceda abathengi bafezekise izibonelelo zoqoqosho

Emva kofakelo kunye nokusebenza kwe-WVD-II yokususa i-varnish yokucoca i-oyile, ingxaki yobushushu be-injini ye-steam thrust ethwele i-TI31061B ebangelwa ngumthengi yasonjululwa ngokupheleleyo, kunye nelahleko enkulu ebangelwe kukuvalwa kweyunithi yoxinzelelo lwegesi yokuqhekeka. kuphetshwa(Ukukrazula iyunithi yokuncipha kwegesi ukuqala kwaye umise ubuncinci iintsuku ezi-3, ilahleko yezigidi ezi-4RMB;buyisela i-thrust bearing ye-injini yomphunga ngosuku olu-1, ilahleko ye-1 yesigidiRMB), kunye nokulahleka kweendawo ezisecaleni ezibangele ukujikeleza kunye nokutywina (phakathi kwe-5 yezigidi ~ 8 yezigidiRMB).Iyunithi yazaliswa ngeebhareli ze-160 zeoli, kwaye iimveliso zeoli zafikelela kumgangatho weoli, zigcina iindleko zokutshintshwa kweoli ye-500,000 RMB.

Umthengi unelisekile kakhulu ngomphumo wokususwa kwe-varnish kunye nokuphuculwa kwezikhombisi zeoli.Umatshini womthengi we-ethylene ezintathu zonke zixhotyiswe ngesicoci se-oyile seWinsonda ivanishi.
