Amaphampu endle anomsebenzi wokuhambisa uketshezi oluguquguqukayo kakhulu ngokwakheka, oluvame ukuqukatha amavolumu angalindelekile ezinto ezisusayo, izinto ezinemicu, kanye namakhemikhali agqwalisayo. Ukuqonda izindlela ezithile zokwehluleka ezihlobene nale ndawo eyinselele kuyisinyathelo sokuqala sokuqalisa amasu okunciphisa asebenzayo kanye nokwandisa isikhathi sokuphila kwemishini.

Izinto eziqinile, imicu, ulwelwesi, kanye nodaka oluhlabayo

Ukuba khona kwezinto eziqinile, imicu, ulwelwesi, kanye nodaka oluhlabayo kuyisongo esivame kakhuluizivalo zemishini ekusetshenzisweni kwendle. Udaka lwamanzi amdaka lungaqukatha ukugxila kwezinto eziqinile kuze kufike ku-8% kuya ku-10% ngesisindo, lugcwele kakhulu utshani olusekelwe ku-silica olusebenza njengenhlanganisela yokugaya ebusweni besivalo. Lapho izinhlayiya ezinkulu kunesikhala sefilimu yoketshezi esingu-1-to-3-micron zingena esibonakalayo, zibangela ukuguguleka okukhulu, ukugoba, kanye nokugoba kwe-radial ebusweni besivalo. Izinto ezine-fiber, ezivame ukubizwa ngokuthi “ukuguguleka,” zibeka usongo lwesibili ngokugoqa izingxenye zesivalo ezijikelezayo. Lokhu kugoba kungavimbela ukuhamba kweziphethu noma izimbobo, kuvimbele ubuso besivalo ukuthi bugcine ingcindezi efanele yokuxhumana futhi kuholele ekuvuzeni okusheshayo, okungalawuleki.

Ukuphuma komile, ukugcotshwa okubi, kanye nokushaqeka kokushisa

Izivalo zemishini zithembele kufilimu yoketshezi oluzinzile ukuze kugcotshwe futhi kushabalaliswe ukushisa. Ukusebenza okomile kwenzeka lapho ipompo ilahlekelwa yi-prime, isebenza ngokumelene ne-valve yokukhipha evaliwe, noma ibhekana nokufakwa komoya okunzima, okubangela ukuthi ifilimu yoketshezi ishise. Ngaphandle kwalokhu kugcotshwa, i-coefficient yokungqubuzana phakathi kwesivalo ibhekene nokukhuphuka, idale ukushisa okukhulu kwendawo. Amazinga okushisa esibonakalayo sesivalo angadlula ngokushesha u-400°F (204°C) ngaphansi kwezimo zokugijima okomile. Lokhu kugcwala kokushisa kubangela ukushaqeka kokushisa—ikakhulukazi ezintweni ezibuthakathaka njenge-ceramic noma i-silicon carbide—okubangela ukuqhekeka kokucindezeleka okuncane kakhulu okwaziwa ngokuthi ukuhlolwa kokushisa. Ngaphezu kwalokho, ukuvezwa isikhathi eside kulawa mazinga okushisa aphezulu kunciphisa ngokushesha izingxenye ze-elastomeric zesibili, njenge-O-rings, okubangela ukuba ziqine, ziqhekeke, futhi zilahlekelwe amandla azo okuvala.

Ukungahambisani kahle, ukudlidliza, kanye nokucindezela kuyadlula

Izivalo zemishini zidinga izimo zokusebenza eziqondile ukuze zisebenze kahle; ukuphambuka ekuqondeni kweshafti noma ingcindezi yesistimu kungonakalisa kakhulu ubuqotho besivalo. Ukudlidliza okweqile, okuvame ukubangelwa ukungalingani kwe-impeller, ukuguguleka kwamabhereri, noma ukusebenza ngaphandle kweSifunda Esithandwayo Sokusebenza sephampu (i-POR), kuphoqa ubuso besivalo ukuthi buvuleke futhi buvale ngokushesha. Izindinganiso zemboni zithi ukugeleza kweshafti akufanele kudlule amasentimitha angu-0.002 (0.05 mm) ebusweni besivalo; ukudlula lo mkhawulo kusheshisa ukuguguleka kuma-drive pins nezinto eziguquguqukayo. Izinto ezishintshayo zokucindezela, njengesando samanzi noma izehlakalo zokugoba ngokuzumayo, zifaka amaza okwethuka anobudlova ekamelweni lesivalo. Lokhu kuguquguquka kungaguqula okwesikhashana umehluko wokucindezela kulo lonke isivalo, okungenzeka kususe ubuso noma kukhiphe ama-O-rings emiseleni yawo.

Indlela Yokuqhathanisa Izisimbozo Zemishini Zamaphampu Amanzi Angcolile

Ukuzulazula ezicini zobuchwepheshe zezimbobo zomshini kudinga ukuqonda okujulile iphrofayili yokusebenza kwephampu kanye nezici ezithile zemidiya yamanzi angcolile. Ukukhetha ukucushwa kwesimbobo esifanele, i-metallurgy, kanye nohlelo lokusekela kubalulekile ekwandiseni i-Mean Time Between Failures (MTBF) kanye nokunciphisa izindleko zomjikelezo wokuphila.

Izimpawu zokuvala ezilodwa, ezimbili, i-cartridge, nezihlukanisiwe

Ukukhetha phakathi kwe-single, double, cartridge, kanye ne-split seals kunquma kokubili umkhawulo wokusebenza kanye nobunzima bokugcinwa kwephampu.Izimpawu zomshini ezilodwazijwayelekile ekusetshenzisweni kokungcola okunganamandla kodwa azinikezi sisekelo uma kwenzeka ukuphuka. Izivalo ezimbili (ezimbili) zisebenzisa amasethi amabili obuso kanye noketshezi oluvimbelayo, okunikeza indawo ephephile kakhulu yokungasebenzi kahle kodaka olunobuthi obukhulu noma oluhlasela kakhulu. Izivalo ze-cartridge, ezihlanganisa ubuso, iziphethu, kanye ne-gland zibe yiyunithi eyodwa, sezibe yindinganiso yemboni yokulungiswa kwamanzi amdaka; ziqeda isidingo sokulinganisa okunembile kokufakwa, zinciphisa ukwehluleka okuhlobene nokufakwa ngamaphesenti angama-30%. Izivalo ezihlukanisiwe zifakwa kumaphampu amakhulu ahlukanisiwe noma aqondile lapho ukudiliza imishini kubiza kakhulu, okuvumela ukushintshwa kwesivalo ngaphandle kokususa injini noma ukuxhuma.

Ubuso be-seal, ama-elastomer, kanye ne-metallurgy

Izinto ezikhethiwe zobuso be-seal kanye nama-elastomer esibili zinquma ukumelana kwamakhemikhali kanye nokuqina kwenhlanganisela. Ezindaweni zokungcola okunamandla, i-Silicon Carbide (SiC) kanye ne-Tungsten Carbide (TC) yizona ezikhethwa kakhulu zobuso be-seal. I-Silicon carbide inikeza ubulukhuni obungavamile (ngokuvamile cishe ama-Knoop angu-2,500) kanye nokuqhuba kahle kokushisa, okwenza imelane kakhulu nokuguguleka okunamandla kanye nokushaqeka kokushisa. Kwezinto zokuvala zesibili, i-Nitrile ejwayelekile (i-Buna-N) ivame ukuwohloka lapho kukhona amakhemikhali ezimboni axutshwe nemfucuza kamasipala. Ngenxa yalokho, ama-elastomer aklanywe njenge-Fluorocarbon (Viton/FKM) noma i-Ethylene Propylene Diene Monomer (EPDM) ayachazwa, kuye ngokuthi i-pH eqondile kanye nokuqukethwe kwe-hydrocarbon koketshezi kuyini.

Umklamo wegumbi lokuvala, amapulani okuhlanza, kanye noketshezi oluvimbelayo

Indawo yegumbi lokuvalela kumele iphathwe ngenkuthalo ukuqinisekisa ukuthi ihlala isikhathi eside, okufezwa ngezinhlelo ezithile zokuvalela kanye noketshezi oluvimbela amanzi. Endle engcolile kakhulu, i-API Plan 32 isetshenziswa kaningi, ifaka amanzi ahlanzekile, angaphandle okuvalela amanzi ekamelweni lokuvalela ukuze iphakamise ingcindezi futhi isunduze izinto ezisusayo ebusweni bovalela. Ukuze kulungiselelwe uphawu oluphindwe kabili, i-API Plan 53A noma 54 inikeza uhlelo loketshezi oluvimbela amanzi olucindezelwe. Ukuze kuvinjelwe amanzi angcolile ukuthi angangeni ebusweni bovalela, uketshezi oluvimbela amanzi luvame ukugcinwa kumehluko wokucindezela ongu-15 kuya ku-30 ​​PSI ngaphezu kokucindezela okukhulu kwegumbi lokuphampa. Ukwakheka kwegumbi lokuvalela ngokwalo—ngokuvamile kusetshenziswa amabhomu akhulisiwe noma anciphile—kusiza kakhulu ekukhishweni kwezinto eziqinile nge-centrifugal kanye nokushabalaliswa kokushisa kwendawo.

Indlela Yokuvimbela Ukwehluleka Kwesivalo Semishini Yepompo Yendle

Ngisho nesivalo semishini esiklanywe kahle kakhulu sizohluleka ngaphambi kwesikhathi uma siphathwa kabi, sifakwa kabi, noma singanakekelwa kahle. Ukusungula izinqubo eziqinile nezijwayelekile zokufaka kanye nokuqapha isimo kubalulekile ekushintsheni kusuka kumodeli yokulungisa esabelayo kuya esikweni lokuthembeka elisebenzayo.

Ukufakwa, ukulungiswa, kanye nokulawulwa kwe-torque

Ukusebenza kahle ngesikhathi sokufakwa akunakuxoxiswana ngakho. Omakhenikha kumele baqinisekise ukuthi umgodi wephampu kanye negumbi lokuvala kuhlanzwa ngokucophelela futhi kuhlolwe ama-burrs noma ama-scoring. Ukuhlolwa kobukhulu kubalulekile; ubuso begumbi lokuvala kumele buqonde ngqo ku-axis yomgodi ngaphakathi kokubekezelelana okungamasentimitha angu-0.001 nge-intshi ngayinye yobubanzi bomgodi ukuze kuvinjelwe ukungalungi kahle kwe-angular. Ukulawulwa kwe-torque ngesikhathi sokuqinisa i-gland kubaluleke ngokulinganayo. Ukuqina okungalingani kwama-gland nuts kungaphazamisa ubuso bokuvala obungaguquki, kudale izikhala ezincane ezivumela ukuvuza. Ochwepheshe kumele basebenzise ama-torque wrench alinganisiwe futhi balandele ukulandelana okuqinile kokuqinisa iphethini ukuze kuqinisekiswe ukucindezelwa okufanayo kwe-gland gasket kanye nokufana okuphelele kobuso bokuvala.

Ukuhlolwa, ukugcotshwa, ukudlidliza, kanye nokuhlolwa kokuvuza

Ukuqapha isimo esivamile kusebenza njengomugqa wokuqala wokuzivikela ekuhlulekeni okubi kakhulu. Abasebenzi bokulungisa kufanele benze ukuhlolwa okubonakalayo njalo ukuthola izimpawu zokuqala zokuphelelwa uketshezi oluvimbekile noma oluvimbekile. Ukuhlaziywa kokudlidliza, okunamathela ezindinganisweni ze-ISO 10816, kunikeza idatha esebenzisekayo mayelana nempilo yokuthwala, ibhalansi ye-impeller, kanye nokuphambuka komgodi ngaphambi kokuba lezi zinkinga zibhubhise uphawu ngomshini. Ezinhlelweni ezimbili zokuvala ezifakwe ama-reservoirs oketshezi oluvimbekile, ukuqapha ama-pressure gauges kanye namazinga oketshezi kubalulekile; ukwehla okungazelelwe kokucindezela kokuvimbela noma ukushintsha kombala woketshezi ngokuvamile kubonisa ukuphuka kobuso bokuvala kwangaphakathi. Ngaphezu kwalokho, ukuhlolwa kwe-thermographic kwe-seal gland kungathola ukukhiqizwa kokushisa okungavamile okubonisa ukugcotshwa okungaphansi noma ukubopha ubuso.

Ukuhlaziywa kwembangela yokwehluleka okuphindaphindiwe

Uma uphawu lomshini luhluleka, ukulishintsha nje ngaphandle kokuphenya imbangela eyisisekelo kuqinisekisa ukwehluleka okuphindaphindiwe. Ukusebenzisa inqubo yokuhlaziywa kwezimbangela eziyisisekelo (RCA) ehlelekile kuhilela ukuhlolwa kwe-forensic kwezingxenye ezihlulekile. Isibonelo, uma ubuso bophawu bubonisa ukuqhakaza, i-RCA ingase ikhombe ekushiseni koketshezi phakathi kobuso, okubonisa ukupholisa okunganele noma ukusebenza ngaphandle kwe-envelope yokucindezela ecacisiwe. Uma ama-drive pin enqunyiwe, ukuhlaziywa kuzogxila ku-torque yokuqalisa enzima noma izimo zokusebenza okomile. Ngokubhala ngokucophelela izindlela zokwehluleka, izimo zokusebenza, kanye namalogi okulungisa, onjiniyela bokuthembeka bangabona izinkinga zesistimu futhi basunduze i-Mean Time Between Failures (MTBF) benchmark kusukela emjikelezweni wezinyanga ezingu-12 osebenzayo kuya ezinyangeni ezingu-36 noma ngaphezulu eziqhubekayo.

Indlela Yokukhetha Isu Elifanele Lokuvala

Ukuthuthukisa isu eliphelele lokuvala kudlula izincazelo zobuchwepheshe; kudinga indlela ephelele yokuphathwa kwempahla, ukuthengwa kwempahla, kanye nomnotho womjikelezo wokuphila. Abaphathi bezikhungo kumele balinganisele imikhawulo yesabelomali esheshayo nemigomo yokuthembeka yesikhathi eside ukuze bandise izindleko eziphelele zobunikazi bengqalasizinda yabo yokupompa.

Izinqumo zokulungisa, ukulungisa kabusha, noma ukuthuthukisa

Abaphathi bemishini bavame ukubhekana nesinqumo sokuthi kufanele balungise ingxenye ehlulekile, bafake kabusha ipompo ngohlobo oluhlukile lwesivalo, noma bathuthukise lonke uhlelo lokuvala. I-heuristic yemboni eyamukelwa kabanzi inquma ukuthi uma izindleko zokulungisa isivalo somshini zidlula u-50% wentengo yesivalo esisha, ukuthenga iyunithi entsha kuyisinqumo esinengqondo ngokwezomnotho. Kodwa-ke, uma ipompo ethile ibhekana nokwehluleka okungapheli—njengokufaka esikhundleni sesivalo sengxenye njalo ezinyangeni eziyisithupha—kuyadingeka ukufakela kabusha isivalo sekhatriji esiqinile noma uhlelo lwesivalo esiphindwe kabili olunecebo lokulawula imvelo. Ukuthuthukiswa kubaluleke kakhulu lapho izimo zenqubo zishintsha, njengokwanda kwezinto eziqinile ezimisiwe (TSS) noma ukungeniswa kokungcola kwamakhemikhali okunamandla kakhulu emfuleni wamanzi angcolile.

Ukulinganisela intengo yokuthenga nezindleko zomjikelezo wokuphila

Ukugxila kuphela entengweni yokuqala yokuthenga yesivalo somshini kuyiphutha elivamile lokuthenga elikhuphula izindleko zokusebenza zesikhathi eside. Izindleko Zobunikazi Eziphelele (i-TCO) zihlanganisa imali yokuqala esetshenzisiwe, umsebenzi wokufaka, ukusetshenziswa kwamandla, ukulungiswa koketshezi oluvimbelwe, kanye, okubaluleke kakhulu, izindleko zesikhathi sokungasebenzi. Isibonelo, ukuthenga isivalo sengxenye eyisisekelo ngo-$500 kungase kubonakale kungabizi kakhulu uma kuqhathaniswa nesivalo sekhatriji esenziwe ngo-$1,500. Kodwa-ke, uma isivalo sengxenye sidinga ukulinganiswa okuqondile ngesandla, okuholela emaphutheni okufaka njalo kanye nokulahlekelwa okungu-$3,000 ngesikhathi sokungasebenzi kanye nomsebenzi ophuthumayo ngokuhluleka ngakunye, isivalo sekhatriji siletha izindleko eziphansi kakhulu zomjikelezo wokuphila. Ngaphezu kwalokho, imiklamo yobuso besivalo esisebenzisa amandla inganciphisa ukuhudula kwenjini, okuholela ekongeni kagesi okulinganiselwe esikhathini sokusebenza seminyaka eyi-10.

Imigomo yokucacisa kanye nokugcinwa

Ukuze kuqinisekiswe ukuhambisana nokuthembeka, izikhungo zamanzi amdaka kumele zisungule izindlela eziqinile zokuqinisekisa kanye nokugcinwa kwazo kulo lonke imikhumbi yazo. Ukulinganisa kunciphisa ubunzima bempahla futhi kunciphisa umthwalo wokuqeqesha abasebenzi bokulungisa. Imininingwane kufanele ichaze ngokucacile izinto zokwakha ezamukelekayo, izilinganiso zokucindezela kanye nokushisa ezidingekayo, kanye nemibhalo yokulawula ikhwalithi edingekayo evela kumenzi. Eziteshini zokuphakamisa zikamasipala ezisindayo, onjiniyela bavame ukucacisa izivalo ezihlangabezana noma ezidlula amazinga e-API 682 Isigaba 1 noma 2, okuqinisekisa izinga eliphezulu lokuqina. Imininingwane yokulungisa kumele futhi iphoqelele ukusetshenziswa kweIzingxenye eziqinisekiswe yi-OEMukulungiswa kanye nokuchaza izikhawu eziqinile zokufakwa koketshezi oluvimbekile kanye nokuhlolwa kwesisekelo sokudlidliza, ngaleyo ndlela kuqiniswe indlela yokuphatha ingqalasizinda yamanzi angcolile.
