Gufunga valve yo gusohokeramo mu gihePompe zikoresha centrifugalibikorwa bitera ingaruka nyinshi za tekiniki.
Ihindagurika ry'ingufu ritagenzurwa n'ubusumbane bwa thermodynamic
- 1.1 Mu gihe cy’ifungwa ry’ubushyuhe buringaniye, hafi ya ingufu zose zinjira zihinduka ingufu z’ubushyuhe. Ingufu z’ubushyuhe ntizishobora gukuraho ubushyuhe, bigatuma ubushyuhe bwo mu cyumba cy’ipompe buzamuka cyane. Gukomeza gukora bizatuma imyuka y’ubushyuhe ihinduka, bikihutisha ishyirwa mu bikorwa rya karuboni mu bikoresho bifunga.
1.2 Kunanirwa kwa sisitemu yo gufunga Mu gihe cy'ubushyuhe bwinshi n'ubushyuhe bw'icyuma, agakoresho ka mashini gashingira ku mavuta n'ubukonje bw'icyuma bizatuma kananirwa gushyuha cyane - agakoresho ka mashini kazaba gafite ubushyuhe bwumutse kandi igice cy'icyuma kikatwikwa.
Imihangayiko idasanzwe ya tekiniki
- 2.1 Imbaraga z'imirongo zirenga Imbaraga z'imirongo zifunga zivali zikunze kuba inshuro 1.5-5 z'imikorere isanzwe, kandi umutwaro w'imirongo ushobora kugera cyangwa ukarenga umupaka wayo, bigatuma agasanduku k'imirongo gacikamo ibice cyangwa agasanduku kagahinduka.
2.2 Kwangirika kw'umuvuduko n'umunaniro Itandukaniro mu kwaguka k'ubushyuhe riterwa n'ubushyuhe bwinshi ritera guhinduka k'ubushyuhe cyangwa umuvuduko w'ubushyuhe, icyuho kidasanzwe hagati y'impeller n'aho ipompe ikorera, hamwe n'ingaruka z'umutwaro utaringaniye wa hydraulic, bigatuma imikorere ya rotor yangirika, umuvuduko ukiyongera, kandi ibice bikangirika.
Kwangirika kw'ibice n'ibintu byangiritse
3.1 Inyongera ya NPSH inverted medium vaporization [ituma inyongera ya cavitation (NPSH) y'igikoresho iba iri hasi ugereranyije na NPSHr ikenewe ya pompe], ikora uduce tw'umuvuduko, kandi umuraba w'ihungabana uterwa no kugwa kw'uduce tw'umuvuduko ushobora kugera kuri 690MPa, bigatuma ikirenge cy'umuvuduko w'amazi gicikamo ibice n'ibishishwa by'ubuki.
3.2 Kwangirika kw'imiterere ya metallographic Ku byuma bitwara ibyuma bitagira umugese (austenitic stainless steel impellers), ubushobozi bwo gukurura ibintu bushobora kubaho ku bushyuhe bwinshi bwo mu gace, kandi igipimo cyo kwangirika hagati y'uduce twinshi kiziyongera kandi imbaraga zo gukurura zikagabanuka. Ku byuma bitwara ibyuma bitwara ibyuma bitagira umugese (carbon steel impellers), ibibazo ku bushyuhe bwinshi ni ingenzi cyane, nko kugabanya ubushyuhe no gukuraho karuboni mu bushyuhe bwinshi, bigatuma imbaraga zo hejuru zigabanuka na politiki rusange; Iyo irimo imyanda nka sulfur na fosifore, biroroshye kuyitandukanya ku mbibi z'ibinyampeke ku bushyuhe bwinshi, bigatera ubushyuhe butoroshye no gucikagurika byoroshye mu gihe cyo kuyikoresha; Mu gihe cy'ubushyuhe bwinshi bw'igihe kirekire, icyuma cya karuboni ntigishobora kwihanganira gucikagurika neza, kandi ubushyuhe bwinshi bwo mu gace bushobora kwihutisha gucikagurika kw'ibinyampeke, amaherezo bikazatuma impeller ivunika cyangwa inanirwa gucika intege.
Ingaruka z'umutekano wa sisitemu n'ubukungu
4.1 Umuvuduko w'igitutu cy'icyuma gitwara umuvuduko urenze urugero kandi imikorere ya valve ifunga ituma igitutu cyo gusohora ipompo kigera kuri 120-150% by'agaciro kagenwe, kandi hari ibyago byo kunyura mu gitutu cy'umuvuduko w'umutekano, bishobora gutuma umuvuduko usohoka cyangwa guturika k'umuyoboro w'amazi ucika.
4.2 Ikiguzi cy'ingufu zikoreshwa n'ingufu zo kubungabunga imashini zikoresha ingufu nyinshi Gufunga imashini zikoresha ingufu ni "imimerere mibi" y'imashini zikoresha ingufu zikoresha ingufu mu gihe gito, kandi gukora igihe kirekire bizatera kwangirika gukomeye ku bikoresho, kandi ikiguzi cy'isuku rusange gishobora kwiyongeraho inshuro 3-10.
Guhungabana kw'imikorere y'itangazamakuru ryihariye
Ku bijyanye n'ingufu zihindagurika (urugero: LPG), imikorere ya valve ifunze izihutisha ubushyuhe bw'igice cy'amazi, kandi urujya n'uruza rw'amazi rugizwe n'ibice bibiri mu cyumba cy'ipompe ruzatuma habaho impinduka zitunguranye z'urujya n'uruza, bigatuma imbaraga zo mu ruhande zihindagurika ziyongera kandi zikihutisha kwangirika kw'ibice.
Uburambe mu nganda n'ibisabwa bisanzwe
6.1 Uburambe mu nganda Dukurikije uburambe nyakuri mu gukoresha imashini, igihe ntarengwa cyo gukora cya valve ya centrifugal pump ntikigomba kurenza iminota 2, kandi ubusanzwe ni umunota 1. Ni byiza gushyiraho sisitemu yo kugenzura interlock kugira ngo itangire gahunda yo kurinda kuzimya iyo valve yo gusohokera ifunze kandi inshuro nyinshi.
6.2 Ibisobanuro bisanzwe bisaba ko ibipimo ngenderwaho bya API 610 12th Edition bivuga ko zimwe mu pompe zifite ingufu nyinshi, zikozwe mu buryo bufatika cyangwa zifite ibyiciro byinshi zizamuka cyane ubushyuhe iyo valve ifunze, ibyo bigatuma igerageza ritagerwaho cyangwa ritekanye iyo valve ifunze. Izamuka ry'ubushyuhe rifitanye isano rya hafi n'ubucucike bw'ingufu. Ubucucike bw'ingufu PD, bushobora gupimwa nka:
Igipimo cya P: Ingufu kuri buri cyiciro iyo amazi ari muri hp (cyangwa MW)
D imp: Ingano y'umurambararo wa impeller muri in. (cyangwa m)
Umunwa wa D: Umunwa wa flange usohoka muri in. (cyangwa m). Ku pompe zisukwa inshuro ebyiri, zifite icyiciro kimwe, umunwa wa D ni umunwa wa flange usohoka.
Agaciro gasanzwe k’ingenzi kuri PD ni 0.286 hp/in.3 (13 MW/m3), inyuma y’aho ni byiza kudakoresha pompe ifunze valve yo gusohokera mu gihe cyo gupima imikorere.
