Q. Nchiyani chimapangitsa mpope wamoto kukhala wosiyana ndi mitundu ina ya mapampu?

A. Choyamba, amakwaniritsa zofunikira za NFPA Pamphlet 20, Underwriters Laboratories ndi Factory Mutual Research Corporation pofuna kudalirika ndi ntchito zosalephera pansi pa zovuta ndi zovuta kwambiri. Izi zokha ziyenera kuyankhula bwino zamtundu wazinthu za TKFLO ndi mawonekedwe apamwamba kwambiri. Mapampu oyaka moto amafunikira kuti apange mitengo yotsika (GPM) ndi kukakamiza kwa 40 PSI kapena kupitilira apo. Kuphatikiza apo, mabungwe omwe tawatchulawa amalangiza kuti mapampu amayenera kutulutsa osachepera 65% ya mphamvu imeneyo pa 150% ya mayendedwe ovotera - ndipo nthawi yonseyi akugwira ntchito yokweza mapazi 15. Ma curve a magwiridwe antchito ayenera kukhala oti mutu wotseka, kapena "churn," umachokera ku 101% mpaka 140% ya mutu wovoteledwa, kutengera tanthauzo la mawuwo. Mapampu amoto a TKFLO saperekedwa kwa ntchito yopopera moto pokhapokha atakwaniritsa zofunikira za mabungwe onse.

Kupitilira mawonekedwe a magwiridwe antchito, mapampu amoto a TKFLO amawunikidwa mosamala ndi onse awiriNFPAndi FM chifukwa chodalirika komanso moyo wautali kupyolera mu kusanthula mapangidwe awo ndi zomangamanga. Kukhulupirika kwa casing, mwachitsanzo, kuyenera kukhala koyenera kupirira kuyesedwa kwa hydrostatic katatu kukakamiza kopitilira muyeso popanda kuphulika! Kapangidwe ka TKFLO kocheperako komanso kopangidwa bwino kamatipatsa mwayi wokwaniritsa izi ndi mitundu yathu yambiri ya 410 ndi 420. Mawerengedwe a uinjiniya pakukhala ndi moyo, kupsinjika kwa bolt, kutembenuka kwa shaft, ndi kumeta ubweya wa ubweya ziyeneranso kuperekedwa kwaNFPA. ndi FM ndipo ziyenera kugwera m'malire osamala kuti zitsimikizire kudalirika kwambiri. Pomaliza, zofunikira zonse zoyambilira zikakwaniritsidwa, mpopeyo ndi wokonzeka kuyesedwa komaliza kwa certification kuti achitire umboni ndi oyimira kuchokera ku mayeso a UL ndi FM Performance adzafuna kuti ma diameter angapo awonetsedwe mogwira mtima, kuphatikiza ochepera komanso opambana, ndi angapo mu pakati.

Q. Kodi pampu yozimitsa moto imakhala yotani?

A. Nthawi zotsogola zimatha masabata 5 mpaka 8 kuchokera pomwe oda atulutsidwa. Tiyimbireni zambiri.

Q. Kodi njira yosavuta yodziwira kasinthasintha wa mpope ndi iti?

A. Pampopi yopingasa yokhala ndi zigawo zozimitsa moto, ngati mwakhala pa mota moyang'anizana ndi mpope wozimitsa moto, kuchokera pamalo owoneka bwino mpope imakhala kudzanja lamanja, kapena motsata mawotchi, ngati kuyamwa kukuchokera kumanja ndikutulutsa. ikulowera kumanzere. Zosiyana ndi zomwe zimachitika ndi dzanja lamanzere, kapena kuzungulira koloko. Chofunika kwambiri ndi pamene mukukambirana nkhaniyi. Onetsetsani kuti mbali zonse ziwiri zikuyang'ana chopopera chopopera kuchokera mbali imodzi.

Q. Kodi mainjini ndi ma mota amakula bwanji papampu zozimitsa moto?

A. Ma motors ndi injini zoperekedwa ndi mapampu amoto a TKFLO amakula molingana ndi UL, FM ndi NFPA 20 (2013), ndipo amapangidwa kuti azigwira ntchito pamalo aliwonse apakati pa mpope wamoto popanda kupitirira chizindikiro cha motor nameplate service factor, kapena kukula kwa injini. Osapusitsidwa kuganiza kuti ma motors ndi akulu okha mpaka 150% ya mphamvu ya nameplate. Si zachilendo kuti mapampu ozimitsa moto azigwira ntchito mopitirira 150% ya mphamvu zake (mwachitsanzo, ngati pali hydrant yotseguka kapena chitoliro chosweka kunsi kwa mtsinje).

Kuti mudziwe zambiri, chonde onani NFPA 20 (2013) ndime 4.7.6, UL-448 ndime 24.8, ndi Factory Mutual's Approval Standard for Split Case Fire Pumps, Class 1311, paragraph 4.1.2. Ma injini ndi mainjini onse operekedwa ndi mapampu ozimitsa moto a TKFLO amakula molingana ndi cholinga chenicheni cha NFPA 20, UL , ndi Factory Mutual.

Popeza ma mota opopera moto sakuyembekezeka kuti aziyenda mosalekeza, nthawi zambiri amakula kuti agwiritse ntchito mwayi wa 1.15 motor service factor. Chifukwa chake mosiyana ndi madzi apanyumba kapena ntchito zapampu za HVAC, mota yapopu yamoto nthawi zonse imakhala "yosadzaza" pamapindikira. Malingana ngati simukupitirira gawo la ntchito ya motor 1.15, ndilololedwa. Kupatulapo apa ndi pamene variable speed inverter duty electric motor imagwiritsidwa ntchito.

Q. Kodi ndingagwiritse ntchito lupu ya mita yothamanga m'malo mwa mutu woyeserera?

A. Lopo ya mita yothamanga nthawi zambiri imakhala yothandiza pamene madzi ochuluka akuyenda kudzera pa milomo ya UL Playpipe imakhala yovuta; komabe, mukamagwiritsa ntchito chotchinga chotsekeka cha mita kuzungulira pampu yamoto, mutha kuyesa mapampu amtundu wa hydraulic, koma simukuyesa madzi, omwe ndi gawo lofunikira kwambiri papampu yamoto. Ngati pali chotchinga cha madzi, izi sizidzawonekera ndi lopu ya mita yothamanga, koma ndithudi zidzawululidwa poyesa pampu yamoto ndi hoses ndi Playpipes. Pachiyambi choyamba cha makina opopera moto, nthawi zonse timaumirira pa madzi oyenda kudzera mu dongosolo kuti titsimikizire kukhulupirika kwa dongosolo lonse.

Ngati lopu ya mita yothamanga ibwezeredwa kumadzi -- monga thanki yamadzi yomwe ili pamwamba pa nthaka - ndiye pansi pa dongosololi mudzatha kuyesa mpope wamoto ndi madzi. Ingoonetsetsani kuti mita yanu yoyendera ndi yoyezedwa bwino.

Q. Kodi ndiyenera kuda nkhawa ndi NPSH pamapulogalamu a pampu yamoto?

A. Nthawi zambiri. NPSH (net positive suction head) ndichinthu chofunikira kwambiri pakugwiritsa ntchito mafakitale, monga chakudya cha boiler kapena mapampu amadzi otentha. Ndi mapampu amoto, komabe, mukulimbana ndi madzi ozizira, omwe amagwiritsa ntchito mphamvu zonse zam'mlengalenga kuti mupindule. Mapampu amoto amafunikira "kusefukira kwamadzi," komwe madzi amafika ku chopondera kudzera mu mphamvu yokoka. Mufunika izi kuti mutsimikizire pompano 100% yanthawiyo, kuti mukakhala ndi moto, mpope wanu umagwira ntchito! Ndizotheka kukhazikitsa pampu yamoto yokhala ndi valve ya phazi kapena njira zina zopangira priming, koma palibe njira yotsimikizira 100% kuti mpopeyo idzagwira ntchito bwino ikaitanidwa kuti igwire ntchito. M'mapampu ambiri oyamwa kawiri kawiri, zimangotenga pafupifupi 3% ya mpweya mu bokosi la mpope kuti mpope isagwire ntchito. Pachifukwa ichi, simungapeze wopanga mpope wamoto wokonzeka kugulitsa pampu yamoto kuti akhazikitse chilichonse chomwe sichimatsimikizira "kusefukira kwa madzi" ku mpope wamoto nthawi zonse.

F. Kodi mungayankhe liti mafunso enanso patsamba lino la FAQ?

A. Tidzawawonjezera pakabuka mavuto, koma khalani omasukakukhudzanaife ndi mafunso anu!
