Ukungalingani, Uxinzelelo lwePipe, kunye neNyawo ethambileyo

Ulungelelwaniso loomatshini ludlulela ngaphaya kwezixhobo zepompo zangaphakathi ukuya kwipompo yonke kunye nomqhubi wemoto. Ukungalingani phakathi kwepompo kunye neeshafti zemoto kuvelisa amandla amakhulu e-radial kunye ne-axial adluliselwa ngqo kwitywina loomatshini. Nangona ii-couplings eziguquguqukayo zinokuthwala ukungalingani okuncinci, aziyisusi imikhosi edluliselwe kwi-shaft yepompo. Imigangatho yeshishini iyalela ukuba ukuqhutywa kweshafti kungadluli kwi-0.002 intshi Ukufundwa kweSikhombisi esipheleleyo (TIR) ​​ebusweni betywina.

Ukongeza ekungalungelelaniseni kweshaft, uxinzelelo lwepayipi kunye neemeko zeenyawo ezithambileyo ziphazamisa kakhulu i-casing yepompo. Xa iipayipi ezinzima zinyanzelwa ukuba ziqhagamshelene neeflange zepompo ngaphandle kwenkxaso efanelekileyo, i-casing iyajika, isusa i-standalone seal gland xa ithelekiswa ne-rotary shaft. Oku kungalungelelanisani kwe-angular kunyanzela ubuso be-seal ukuba buvuleke kwaye buvale kancinci ngokujikeleza ngakunye, into eyaziwa ngokuba 'kukulandelela ubuso.' Kwizantya zemoto eziqhelekileyo ezifana ne-3,600 RPM, ubuso be-seal abukwazi ukuphendula ngokukhawuleza ngokwaneleyo ukuba buhlale buvaliwe, nto leyo ebangela ukuvuza okukhulu. Ukubeka iliso kwi-vibration kunokuhlala kubonwa ezi ngxaki, kunye nemida yokungcangcazela eyamkelekileyo edla ngokuwela ngaphantsi kwe-0.15 intshi/isekhondi ye-RMS kwiipompo ze-centrifugal eziphilileyo.

Izizathu Zemeko Yokusebenza

Indawo yokusebenza ngaphakathi kwebhokisi yepompo ilawula ngokuthe ngqo ixesha elide letywina loomatshini bepompo ye-centrifugal. Utshintsho lwenkqubo, ukuphazamiseka kwenkqubo, kunye nokuphambuka kwiindawo zoyilo lwe-hydraulic ezicwangcisiweyo zepompo kudala iimeko ezinobungozi ezitshabalalisa ubuso betywina kunye nee-elastomers zesibini. Itywina loomatshini lixhomekeke ngokupheleleyo kulwelo olupompelweyo okanye i-flush yangaphandle ukuze kuphole kwaye kuthanjiswe; ke ngoko, ukuzinza kwemeko yolwelo akunakuxoxiswana ngako.

Ukusebenzisa ipompo ye-centrifugal ngaphandle kweeparamitha zayo ezimiselweyo kunyanzela itywina loomatshini ukuba lifunxe ubunzima bokungazinzi kwe-hydraulic. Ukuqonda nokunciphisa iimeko zokusebenza ezimbi kubalulekile ekuthinteleni ukuvuza kwetywina ngaphambi kwexesha.

Ukusebenza okomileyo kunye nokuthambisa okubi

Ukubaleka okomileyo mhlawumbi yeyona meko iyingozi kakhulu yokusebenza kwe-centrifugal pump mechanical seal. Xa i-pump ilahlekelwa yi-prime, okanye ukuba ukuhamba komoya kuphazamisekile, ubuso be-seal abufumani ifilimu yabo yolwelo lokuthambisa. Ngaphandle kokuthambisa, i-coefficient of friction phakathi kobuso obujikelezayo nobumileyo iyanda, nto leyo ekhokelela ekuveliseni ubushushu obukhawulezileyo nobugqithisileyo. Amaqondo obushushu akwindawo ethile kubuso be-seal anokudlula ngokulula i-400°F (204°C) kwimizuzwana embalwa emva kokuba kwenzeke okomileyo.

Olu tshintsho lobushushu olukhawulezileyo lubangela ukuba ubuso besitywina bukhule ngokungalinganiyo, nto leyo ekhokelela ekuphazamisekeni okukhulu kobushushu kunye 'nokujonga ubushushu'—uthungelwano lweemfanta zeradial ezincinci ezisasazeka kubuso besitywina. Nje ukuba kuhlolwe ubushushu, ubuso besitywina busebenza njengezixhobo zokusika, butshabalalisa ngokukhawuleza kwaye bubangele ukuvuza okukhulu xa kuphinda kufakwe ulwelo. Ukugcina i-Net Positive Suction Head eyaneleyo ekhoyo (NPSHa) idlula imfuneko (NPSHr) ngomda okhuselekileyo kubalulekile ekuthinteleni ukutsha kunye nokubaleka okomileyo kubuso besitywina.

Ukuhamba Okungacwangciswanga, Ukungcangcazela, kunye noxinzelelo lobushushu

Ukusebenzisa ipompo ye-centrifugal kude kakhulu neBest Efficiency Point (BEP) yayo kubangela ukungazinzi okukhulu kwe-hydraulic. Xa ipompo isebenza ngaphantsi kwe-60% ye-BEP yayo okanye iimeko ezikufutshane ne-dead-head, ukusasazwa koxinzelelo lwangaphakathi olujikeleze i-impeller kuba yinto engalinganiyo kakhulu. Olu kungalingani luvelisa imithwalo emikhulu ye-radial thrust ejika i-pump shaft. Ukuphambuka kwe-shaft kutshintsha i-geometry yokusebenza kwe-mechanical seal, okuthintela ubuso ukuba buhlale busicaba kwaye bufana.

Ngokufanayo, ukusebenza kwiimeko zokuphelelwa ngamandla (kude ngasekunene kwe-BEP) kunokukhokelela ekutsalweni kwe-cavitation. Ukuqhushumba kwamaqamza omphunga ngexesha lokutsalwa kwe-cavitation kuvelisa amaza okutshayiswa ahamba rhoqo, aphezulu, ahamba nge-pump shaft. Oku kungcangcazela kunokuqhekeza ubuso be-brittle seal, njenge-silicon carbide okanye i-tungsten carbide, kwaye kususe ii-O-rings ezinamandla. Ngaphezu koko, utshintsho olukhawulezileyo kubushushu benkqubo yolwelo lubangela ukutshayiswa kobushushu, okunokugoba izinto kwaye kuthintele umsantsa ochanekileyo ofunekayo ukulawula ukuvuza.

Imiba yoKhetho lwezinto kunye neSicwangciso sokutywina

Ukungafani phakathi kwezinto zesitywino kunye nolwelo lwenkqubo kuhlala kukhokelela ekuwohlokeni kweekhemikhali, ukuguguleka okurhabaxa, kwaye ekugqibeleni, ukuvuza. Ukukhethwa kwezinto ezifanelekileyo kunye nesicwangciso sesitywino kufuna ukuqonda okubanzi malunga nokwakheka kweekhemikhali zolwelo, i-pH, i-viscosity, kunye nomxholo weenxalenye.

Ukuthembela kwiindlela ezisemgangathweni, ezingasetyenziswanga kwizicelo zeekhemikhali ezinobungozi okanye ezikhethekileyo kakhulu yimbangela eqhelekileyo yokusilela kwesitywina okungapheliyo. Iinjineli kufuneka zisebenzise imilinganiselo eneenkcukacha zokuhambelana kunye nemigangatho yoshishino, efana ne-API 682, ukuqinisekisa ukusebenza kakuhle kwesitywina.

Ubuso obungahambelaniyo, ii-Elastomers, kunye neeFluids

Ubuso betywina obungahambelaniyo kunye nee-elastomers zimele indlela yokusilela ephambili kwizicelo zokucubungula iikhemikhali. Ukuba izinto zokuvala zesibini (ii-O-rings, ii-V-rings, okanye ii-gaskets) azihambelani ngokweekhemikhali nolwelo olupompelweyo, zinokudumba, zinyibilike, okanye zibe buthathaka. Umzekelo, ukusebenzisa ii-O-rings zeNitrile eziqhelekileyo kwisicelo se-solvent esinobushushu obuphezulu kuya kubangela ukudumba kunye nokukhupha ngokukhawuleza, okukhokelela ekuvuza kwangoko. Imida yobushushu be-Elastomer nayo kufuneka ijongwe ngokungqongqo; ngelixa iViton (FKM) ifanelekile kumaqondo obushushu afikelela kwi-400°F (204°C), izicelo ezidlula lo mda zihlala zifuna iiPerfluoroelastomers (FFKM) ezifana neKalrez, ezinokumelana ukuya kuthi ga kwi-600°F (316°C).

Ukukhethwa kwezinto zobuso kubaluleke ngokulinganayo. Ukupompa i-abrasive slurrys kunye nee-carbon-graphite ubuso eziqhelekileyo kuya kubangela ukuguguleka ngokukhawuleza kunye nokuguga. Kwizicelo ze-abrasive, ukuhlanganiswa kobuso obunzima, njengeSilicon Carbide vs Silicon Carbide, kuyimfuneko ukuze kuthintelwe ukukhukuliseka. Imida yokuthelekisa yezinto eziqhelekileyo ichaziwe ngezantsi.

Izitywino zoomatshini ezingatshatanga nezimbini

Isigqibo sokusebenzisa ulwakhiwo lwesitywina somatshini esinye okanye esiphindwe kabini (esiphindwe kabini) sinefuthe elikhulu kulawulo lokuvuza kunye nokuthobela imiqathango yokusingqongileyo.uphawu olunye loomatshiniixhomekeke ngokupheleleyo kwimveliso epompelweyo ukuze ithambise kwaye ngokwemvelo iya kukhupha inqanaba elithile lomphunga emoyeni. Nangona ifanelekile kwiilwelo ezingenabungozi ezifana namanzi okanye iikhemikhali ezithambileyo, izitywini ezilodwa azanele kwiikhompawundi ze-organic eziyingozi kakhulu, ezinokutsha, okanye ezinobungozi (ii-VOC).

Izitywino ezimbini zoomatshini zinezibini ezimbini ezahlukeneyo zobuso betywino kwaye zisebenzisa isithintelo sesibini okanye ulwelo lwe-buffer. Kwisimo setywino ezimbini esicinezelweyo (i-API 682 Udidi 2 okanye 3), ulwelo lwesithiyo lugcinwa kuxinzelelo oluyi-15 ukuya kwi-30 psi oluphezulu kunoxinzelelo lwebhokisi yokuzalisa yepompo. Oku kuqinisekisa ukuba naluphi na ukuvuza kwiindawo zangaphakathi zesitywino kuqulathe ulwelo lwesithiyo olucocekileyo olungena kwinkqubo, endaweni yokuba ulwelo lwenkqubo olunobungozi luphume luye emoyeni. Ukungaphumeleli ukucacisa isitywino esiphindwe kabini kwimisebenzi enobungozi kukungathobeli umthetho kunye nokhuseleko.

Iingxaki zokukhetha isicwangciso sokucofa

Kwanezitywino zoomatshini ezichazwe ngokuchanekileyo zifuna inkqubo efanelekileyo yolawulo lokusingqongileyo, ebizwa ngokuba yi-API piping plan okanye i-seal flush plan. Ezi zicwangciso zenzelwe ukulawula imeko-bume ejikeleze ubuso besitywino ngokulawula ubushushu, uxinzelelo, kunye nokucoceka kolwelo. Isizathu esiqhelekileyo sokuvuza kukusetyenziswa gwenxa okanye ubungakanani obungonelanga bezi zicwangciso zokuhlamba.

Umzekelo, ukusebenzisa i-API Plan 11 (ukujikeleza kwakhona ukusuka ekukhutshweni kwepompo ukuya kwisitywini) akusebenzi ukuba umahluko woxinzelelo awonelanga ukuqhuba ukuhamba okwaneleyo. Ngokwesiqhelo, izinga lokuhamba komoya eliyi-2 ukuya kwi-5 Gallons ngomzuzu (GPM) liyafuneka ukususa ubushushu obuveliswa ziintsika zobuso. Ukuba kusetyenziswa iPlan 32 (ukucoca kwangaphandle okucocekileyo), ulwelo lwangaphandle kufuneka lujongwe ngokungqongqo; ukuphazamiseka konikezelo lwePlan 32 ngoko nangoko kwenza ukuba isitywini se-centrifugal pump mechanical seal singabi nalutha, nto leyo ebangela ukusilela ngokukhawuleza.

Uxilongo kunye noThintelo

Ukutshintsha ukusuka ekulweni nomlilo osebenzayo ukuya kulawulo lokuthembeka olusebenzayo kufuna indlela ecwangcisiweyo yokuxilonga nokuthintela ukuvuza kwetywina loomatshini bepompo ye-centrifugal. Ngokuhlalutya izitywina ezingasebenziyo kunye nokusebenzisa ukujonga imeko ngokungqongqo, izityalo zinokuchonga iindlela ezithile zokusilela kunye nezisombululo ezijolise kuzo. Injongo kukwandisa i-Mean Time Between Failure (MTBF), kunye nezitywina zanamhlanje ezihambelana ne-API 682 kulindeleke ukuba zifikelele kwi-MTBF edlula iinyanga ezingama-36 phantsi kweemeko ezifanelekileyo.

Ukuxilongwa okusebenzayo kuxhomekeke ekudibaneni kohlalutyo lwedatha yokusebenza, ukuhlolwa ngokubonakalayo kwezinto ezingaphumelelanga, kunye nokuzibophelela ekuphuculeni okuqhubekayo ngokusebenzisa amaqhinga okukhusela kunye nokugcina kwangaphambili.

Zihlala zivuza kuba ubuso besitywini bulahlekelwa yifilimu yaso yolwelo oluzinzileyo oluncinci. Izizathu eziqhelekileyo ziquka ukusebenza okomileyo, ukungalungi kakuhle, ukungcangcazela, ukucandeka kwesisu, ukukhetha isitywini ngendlela engafanelekanga, ukufakwa kakubi, ungcoliseko, kunye noxinzelelo okanye ubushushu obugqithisileyo.

Ingaba ukuvuza okuncinci kwetywina loomatshini kuyinto eqhelekileyo?

Ewe. Zonke izitywino zoomatshini zivumela ukufuduka okuncinci kolwelo ukuze kuthanjiswe kwaye kuphole. Kwisitywino esisempilweni, oku kudla ngokuba ngumphunga ongabonakaliyo. Ukuvuza okubonakalayo, ukutshiza, okanye ukwanda ngequbuliso kokuvuza kudla ngokubonisa ukungasebenzi kakuhle.

Ingakanani izinga lokuvuza kwetywina loomatshini elamkelekileyo?

Kuxhomekeke kuhlobo lolwelo, uyilo lwesitywino, isantya, uxinzelelo, kunye nezinto ezisetyenziswayo. Ezinye iinkonzo zilindele ukuba akukho kuvuza kubonakalayo, ngelixa iioyile ezinzima zinokuvumela ukuvuza okuncinci. Nakuphi na ukuvuza okungaphandle kwenkcazelo yompompo okanye yomthengisi wesitywino kufuneka kuphandwe.

Ngaba ukusebenza okomileyo kuyayonakalisa itywina lomatshini wepompo ye-centrifugal?

Ewe. Ukubaleka okomileyo kususa ifilimu yokuthambisa phakathi kobuso besitywini, nto leyo ebangela ukwakheka kobushushu ngokukhawuleza, ukuqhekeka kobuso, umonakalo we-elastomer, kunye nokuvuza. Iimpompo kufuneka zibekwe iprimer efanelekileyo, zivule umoya, kwaye zikhuselwe ngolawulo olufanelekileyo.

Ukungcangcazela kuyichaphazela njani ubomi bokutywinwa koomatshini?

Ukungcangcazela okugqithisileyo kuphazamisa indlela yokunxibelelana kobuso besitywini kwaye kunokonakalisa izipringi, ubuso, ii-O-rings, kunye neebheringi. Kudla ngokunxulunyaniswa nokuqhekeka kwe-cavitation, ukungalingani, ukungalungelelani kakuhle, iibheringi ezigugileyo, okanye ukusebenza kude nendawo efanelekileyo yokusebenza kwepompo.
