Ikibazo. Niki gituma pompe yumuriro itandukanye nubundi bwoko bwa pompe?

A. Ubwa mbere, bujuje ibyangombwa bisabwa mu gatabo ka NFPA 20, Laboratoire zandika hamwe n’isosiyete ikora ubushakashatsi ku ruganda kugira ngo serivisi yizewe kandi idahwitse mu bihe bigoye kandi bisaba.Ukuri kwonyine kugomba kuvuga neza kubicuruzwa bya TKFLO nibiranga ibishushanyo mbonera.Amapompo yumuriro asabwa kubyara umuvuduko wihariye (GPM) hamwe numuvuduko wa 40 PSI cyangwa irenga.Byongeye kandi, ibigo byavuzwe haruguru biratanga inama ko pompe zigomba gutanga byibuze 65% yuwo muvuduko kuri 150% byurugendo rwateganijwe - kandi mugihe cyose gikora kumiterere ya metero 15.Imirongo yimikorere igomba kuba nkiyi gufunga umutwe, cyangwa "churn," biva kuri 101% kugeza 140% byumutwe wagenwe, bitewe nicyo kigo gisobanura ijambo.Amapompo yumuriro ya TKFLO ntabwo atangwa muri serivisi yo kuvoma umuriro keretse yujuje ibisabwa ninzego zose.

Kurenga ibiranga imikorere, pompe yumuriro ya TKFLO isuzumwa neza byombiNFPAna FM yo kwizerwa no kuramba binyuze mu gusesengura igishushanyo mbonera cyabo.Kurwanya ubunyangamugayo, kurugero, bigomba kuba bikwiriye guhangana na hydrostatike yikubye inshuro eshatu umuvuduko ntarengwa wo gukora udaturika!Igishushanyo mbonera cya TKFLO kandi cyakozwe neza kidufasha guhaza ibi bisobanuro hamwe na moderi zacu 410 na 420.Ibiharuro byubuhanga bwo kubyara ubuzima, guhangayikishwa na bolt, guhindagurika kwa shaft, hamwe no guhagarika umutima nabyo bigomba gushyikirizwaNFPA.na FM kandi igomba kuba mumipaka igamije kugenzura neza.Hanyuma, ibyangombwa byose byibanze byujujwe, pompe yiteguye kwipimisha ryanyuma kugirango ibone abahagarariye ibizamini bya UL na FM bizakenera ko ibipimo byinshi byimodoka bizerekanwa neza, harimo byibuze na byinshi, na byinshi muri hagati.

Ikibazo. Ni ikihe gihe gisanzwe cyo kuyobora pompe yumuriro?

A. Ibihe bisanzwe byo kuyobora bikora ibyumweru 5-8 uhereye kurekura itegeko.Hamagara kubisobanuro birambuye.

Ikibazo. Nubuhe buryo bworoshye bwo kumenya kuzunguruka pompe?

A. Kuri pompe yumuriro itambitse, niba wicaye kuri moteri ireba pompe yumuriro, uhereye aha hantu pompe ni ukuboko kwiburyo, cyangwa isaha-isaha, niba guswera biva iburyo no gusohoka ni ugana ibumoso.Ibinyuranye nukuri kubumoso, cyangwa guhinduranya amasaha.Urufunguzo ni ingingo nziza mugihe muganira kuriyi ngingo.Menya neza ko impande zombi zireba pompe kuruhande rumwe.

Ikibazo. Nigute moteri na moteri bifite ubunini bwa pompe yumuriro?

A. Moteri na moteri bitangwa na pompe yumuriro ya TKFLO bifite ubunini ukurikije UL, FM na NFPA 20 (2013), kandi bigenewe gukorera ahantu hose hacuramye pompe yumuriro utarenze ikintu cyerekana moteri, cyangwa ingano ya moteri.Ntukishuke ngo utekereze ko moteri zingana na 150% gusa yubushobozi bwizina.Ntibisanzwe ko pompe yumuriro ikora neza irenze 150% yubushobozi bwagenwe (urugero, niba hari hydrant ifunguye cyangwa umuyoboro wacitse hepfo).

Kubindi bisobanuro, nyamuneka reba NFPA 20 (2013) paragarafu ya 4.7.6, UL-448 paragarafu ya 24.8, hamwe nu ruganda rwo kwemeza uruganda rwo gucana amapompo yumuriro, Icyiciro 1311, paragarafu ya 4.1.2.Moteri zose hamwe na moteri zitangwa na pompe yumuriro wa TKFLO zingana nubushake nyabwo bwa NFPA 20, UL, hamwe nUruganda.

Kubera ko moteri ya pompe yumuriro idateganijwe gukora ubudahwema, akenshi iba ifite ubunini kugirango ikoreshe ikintu cya moteri 1.15.Bitandukanye rero namazi yo murugo cyangwa porogaramu ya pompe ya HVAC, moteri ya pompe yumuriro ntabwo buri gihe iba ifite "kutarenza urugero" kuruhande.Igihe cyose utarenze moteri ya 1.15 ya serivise, biremewe.Ibidasanzwe kuriyi nigihe ikoreshwa ryumuvuduko uhindagurika inverter duty moteri yamashanyarazi ikoreshwa.

Ikibazo. Nshobora gukoresha metero ya flux nkisimbuza umutwe wikizamini?

A. Umuzenguruko wa metero utemba akenshi ni ngirakamaro aho gutembera amazi menshi binyuze muri UL Playpipe nozzles bitoroha;icyakora, mugihe ukoresheje metero ifunze izengurutse pompe yumuriro, urashobora kugerageza pompe imikorere ya hydraulic, ariko ntushobora kugerageza gutanga amazi, nikintu gikomeye muburyo bwa pompe yumuriro.Niba hari imbogamizi ku itangwa ry’amazi, ibi ntibizagaragara hamwe na metero ya flux, ariko rwose bizashyirwa ahagaragara mugupima pompe yumuriro hamwe na hose hamwe na Playpipes.Mugutangira kwambere sisitemu ya pompe yumuriro, duhora dushimangira amazi atemba muri sisitemu kugirango tumenye ubusugire bwa sisitemu yose.

Niba metero ya flux isubizwa mumazi - nk'ikigega cy'amazi kiri hejuru y'ubutaka - noneho muri iyo gahunda uzashobora kugerageza pompe yumuriro hamwe n’amazi yatanzwe.Gusa menya neza ko metero yawe yatembye neza.

Ikibazo. Nkeneye guhangayikishwa na NPSH mubisabwa pompe yumuriro?

A. Ni gake.NPSH (net positif net net) ni ikintu cyingenzi mubikorwa byinganda, nkibiryo byo guteka cyangwa pompe zamazi ashyushye.Hamwe na pompe zumuriro, ariko, urimo guhangana namazi akonje, akoresha ingufu zose zikirere kugirango ubone inyungu zawe.Amapompo yumuriro akenera "umwuzure wuzuye," aho amazi agera kumupompi binyuze muburemere.Ukeneye ibi kugirango wishingire pompe yibanze 100% yigihe, kugirango mugihe ufite umuriro, pompe yawe ikora!Birashoboka rwose gushiraho pompe yumuriro hamwe na valve yamaguru cyangwa uburyo bumwebumwe bwogukora priming, ariko ntaburyo bwo kwemeza 100% ko pompe izakora neza mugihe ihamagariwe gukora.Mubice byinshi byacitsemo kabiri pompe, bifata hafi 3% yumuyaga muri pompe kugirango pompe idakora.Kubera iyo mpamvu, ntuzabona uruganda rukora pompe yumuriro rufite ubushake bwo kugurisha pompe yumuriro mugihe icyo aricyo cyose kitemeza "umwuzure wuzuye" kuri pompe yumuriro igihe cyose.

Ikibazo. Ni ryari uzasubiza ibibazo byinshi kururu rupapuro rwibibazo?

A. Tuzabongerera ibibazo bivutse, ariko twumve nezakuvugananatwe hamwe nibibazo byawe!
