FRQ

Q. Yintoni eyenza impompo yomlilo yahluke kwezinye iintlobo zeempompo?
A. Okokuqala, bahlangabezana neemfuno ezingqongqo ze-NFPA Pamphlet 20, Underwriters Laboratories kunye neFactory Mutual Research Corporation yokuthembeka kunye nenkonzo engasileliyo phantsi kwezona meko zinzima nezinzima. Le nyaniso iyodwa kufuneka ithethe kakuhle ngomgangatho wemveliso ye-TKFLO kunye neempawu zoyilo lweprimiyamu. Iimpompo zomlilo zifunekayo ukuvelisa amazinga athile okuhamba (GPM) kunye noxinzelelo lwe-40 PSI okanye ngaphezulu. Ukuqhubela phambili, ii-arhente ezikhankanywe ngasentla zicebisa ukuba iimpompo kufuneka zivelise ubuncinane i-65% yolo xinzelelo kwi-150% ye-flow flow rated -- kwaye lonke ixesha lisebenza kwi-15 foot lift condition. Iigophe zokusebenza kufuneka zibe njalo ukuba intloko yokuvala, okanye "i-churn," isuka kwi-101% ukuya kwi-140% yentloko ehleliweyo, kuxhomekeke kwinkcazo ye-arhente yegama. Iimpompo zomlilo ze-TKFLO azibonelelwa ngenkonzo yempompo yomlilo ngaphandle kokuba zihlangabezana nazo zonke iimfuno ze-arhente.
Ngaphandle kweempawu zokusebenza, iimpompo zomlilo ze-TKFLO zihlolwe ngononophelo yi-NFPA kunye ne-FM ngokuthembeka kunye nobomi obude ngohlalutyo loyilo kunye nokwakhiwa kwazo. Ukunyaniseka kwe-Casing, umzekelo, kufuneka kube kufanelekile ukujamelana novavanyo lwe-hydrostatic ngokuphindwe kathathu ubuninzi boxinzelelo lokusebenza ngaphandle kokuqhuma! I-TKFLO's compact kunye noyilo oluyinjineli olufanelekileyo luvumela ukuba sanelise le ngcaciso kunye neemodeli zethu ezininzi ze-410 kunye ne-420. Ubalo lobunjineli bokuthwala ubomi, uxinzelelo lwebholithi, ukuphambuka kweshaft, kunye noxinzelelo lokucheba nazo kufuneka zingeniswe kwi-NFPA. kunye ne-FM kwaye kufuneka iwele ngaphakathi kwemida egcinayo ukuqinisekisa ukuthembeka okukhulu. Okokugqibela, emva kokuba zonke iimfuno zangaphambili zifezekisiwe, impompo ilungele uvavanyo lokugqibela lwesatifikethi ukuze kungqinwe ngabameli abavela kwi-UL kunye novavanyo lweNtsebenzo ye-FM iya kufuna ukuba iidiameter ezininzi ze-impeller ziya kuboniswa ngokwanelisayo, kubandakanya ubuncinci kunye nobuninzi, kwaye uninzi phakathi.

Q. Leliphi ixesha eliqhelekileyo lokukhokelela kwimpompo yomlilo?
A. Amaxesha okukhokela aqhuba iiveki ezi-5-8 ukusuka ekukhutshweni komyalelo. Sitsalele umnxeba ngeenkcukacha.

Q. Yiyiphi eyona ndlela ilula yokumisela ukujikeleza kwempompo?
A. Kwimpompo yomlilo yecala elithe tye, ukuba uhleli kwi-motor ejongene nempompo yomlilo, ukusuka kule ndawo iphezulu impompo isesandleni sasekunene, okanye ngokwewotshi, ukuba ukufunxa kuvela ngasekunene kunye nokuphuma. ibheka ngasekhohlo. Okuchaseneyo kuyinyani kujikelezo olusekhohlo, okanye oluchasene newotshi. Undoqo yingongoma ebalulekileyo xa uxubusha lo mbandela. Qinisekisa ukuba omabini amaqela ajonga i-casing yempompo ukusuka kwicala elinye.

Q. Ingaba iinjini kunye neenjini zilinganiswa njani kwiimpompo zomlilo?
A. Iimotor kunye neenjini ezibonelelwa ngeepompo zomlilo ze-TKFLO zilinganiswe ngokwe-UL, FM kunye ne-NFPA 20 (2013), kwaye zenzelwe ukusebenza kuyo nayiphi na indawo ye-curve yepompo yomlilo ngaphandle kokugqithisa i-motor nameplate yenkonzo ye-motor, okanye ubukhulu be-injini. Musa ukukhohliswa ekucingeni ukuba iinjini zilinganiswe kuphela kwi-150% yomthamo we-nameplate. Akuqhelekanga ukuba iimpompo zomlilo zisebenze kakuhle ngaphaya kwe-150% yomthamo olinganisiweyo (umzekelo, ukuba kukho i-hydrant evulekileyo okanye umbhobho ophukileyo ezantsi).
Ukufumana iinkcukacha ezithe vetshe, nceda ujonge kwiNFPA 20 (2013) umhlathi 4.7.6, UL-448 umhlathi 24.8, kunye neFactory Mutual's Approval Standard for Split Case Fire Pumps, Class 1311, paragraph 4.1.2. Zonke iinjini kunye neenjini ezibonelelwa ngeempompo zomlilo ze-TKFLO zilinganiswe ngokweyona njongo ye-NFPA 20, UL, kunye neFactory Mutual.
Ekubeni iimoto zempompo zomlilo azilindelekanga ukuba ziqhube ngokuqhubekayo, zihlala zilinganisa ukuba zithathe inzuzo ye-1.15 yenkonzo yenkonzo yemoto. Ke ngokungafaniyo namanzi asekhaya okanye usetyenziso lwempompo ye-HVAC, i-motor yempompo yomlilo ayisoloko ilingana "engalayishwanga kakhulu" ngapha kwejika. Ngalo lonke ixesha ungadluli kwi-motor 1.15 yenkonzo yenkonzo, ivumelekile. Okungaphandle koku kuxa isantya esiguquguqukayo soguqulo lwe-inverter duty motor electric motor sisetyenziswa.

Q. Ndingasebenzisa i-loop yemitha yokuqukuqela endaweni yesihloko sovavanyo?
A. Ilophu yemitha yokuhamba ikholisa ukusebenza apho ukuqukuqela kwamanzi agqithisileyo ngomgangatho wemibhobho ye-UL Playpipe esemgangathweni ingafanelekanga; nangona kunjalo, xa usebenzisa i-loop yemitha yokuhamba evaliweyo malunga nempompo yomlilo, unokuba uvavanya iimpompo zokusebenza kwe-hydraulic, kodwa AWUVAVAVANYI unikezelo lwamanzi, oluyinxalenye ebalulekileyo yenkqubo yempompo yomlilo. Ukuba kukho isithintelo kunikezelo lwamanzi, oku akuyi kubonakala nge-loop meter loop, kodwa ngokuqinisekileyo kuya kubonakaliswa ngokuvavanya ipompo yomlilo kunye ne-hoses kunye ne-Playpipes. Ekuqalweni kokuqala kwenkqubo yempompo yomlilo, sihlala sigxininisa emanzini ahambayo ngenkqubo ukuqinisekisa ukunyaniseka kwenkqubo yonke.
Ukuba i-flow meter loop ibuyiselwa kunikezelo lwamanzi--njengetanki yamanzi engaphezulu komhlaba -- ngoko phantsi kolu lungiselelo uya kuba nakho ukuvavanya zombini impompo yomlilo kunye nonikezelo lwamanzi. Qiniseka nje ukuba imitha yombane yakho ilinganiswe ngokufanelekileyo.

Umbuzo. Ngaba kufuneka ndikhathazeke malunga neNPSH kwizicelo zempompo yomlilo?
A. Kunqabile. I-NPSH (intloko yokufunxa ene-net positive) yingqwalasela ebalulekileyo kwizicelo zemizi-mveliso, ezifana nokutya kwebhoyila okanye iimpompo zamanzi ashushu. Ngeempompo zomlilo, nangona kunjalo, ujongene namanzi abandayo, esebenzisa lonke uxinzelelo lwe-atmospheric ukuze uzuze. Iimpompo zomlilo zifuna "ukufunxa ngamanzi," apho amanzi afika kwi-impeller yempompo ngokusebenzisa ubunzima. Udinga oku ukuze uqinisekise i-pump prime 100% yexesha, ukuze xa unomlilo, impompo yakho isebenze! Ngokuqinisekileyo kunokwenzeka ukufaka ipompo yomlilo kunye ne-valve yeenyawo okanye ezinye iindlela zokwenza izinto zokufakelwa, kodwa akukho ndlela yokuqinisekisa i-100% ukuba ipompo iya kusebenza ngokufanelekileyo xa ibizwa ukuba isebenze. Kwiimpompo ezininzi zokufunxa eziphindwe kabini, kuthatha kuphela malunga ne-3% yomoya kwingxowa yempompo ukwenza ukuba impompo ingasebenzi. Ngenxa yeso sizathu, awuyi kufumana umenzi wempompo yomlilo ozimisele ukubeka umngcipheko wokuthengisa impompo yomlilo kuyo nayiphi na into yokufakela okungaqinisekisi "ukufunxa ngamanzi" kwimpompo yomlilo ngamaxesha onke.
