1. Iisifafazi somlilo kufanele ifakwe ngemuva kokuhlolwa kwengcindezi yesistimu kanye nokushaywa kwamanzi sekufanelekile.
2. Ngesikhathi sokufakwa kwe-isifafazi, iisifafazi ngeke ihlakazwe noma ishintshwe, futhi kwenqatshelwe ngokuphelele ukunamathisela noma yikuphi ukunamathela ohlotsheni lwekhava yokuhlobisaisifafazi futhi kufihliweisifafazi.
3. Iisifafazi izofakwa nge-wrench ekhethekile, futhi kuvinjelwe ngokuphelele ukusebenzisa ifreyimu yeisifafazi for screwing; Lapho ifreyimu kanye ne-splash tray yeisifafazi zikhubazekile noma izingxenye zokukhululwa zilimele, iisifafazi ngokucaciswa okufanayo kanye nemodeli kuzoshintshwa.
4. Izifafazi ezifakwe ezindaweni ezisengozini yokulimala kwemishini zizohlinzekwa ngamakhava okuzivikela.
5. Lapho ufaka ikhanda lokufafaza, ibanga eliphakathi kwethreyi lokuchaphaza nosilingi, umnyango, iwindi, imbobo noma isithiyo kuzohlangabezana nezidingo zokuklama.
6. Ngaphambi kokufaka, hlola ukuthi imodeli, imininingwane kanye nesizinda sohlelo lokusebenzaisifafazi ukuhlangabezana nezidingo zokuklama. Lapho uhlelo luthathaikhanda lokufafaza elifihliwe, ukuphakama kwepayipi legatsha lokusabalalisa amanzi kanye nobukhulu bokuvula uphahla kufanele kulawulwe ngokunembile.
7. Uma ububanzi obuncane bokufafaza bungaphansi kuka-10mm, kufanele kufakwe isisefo epayipini elikhulu lokusabalalisa amanzi noma ipayipi lokusabalalisa amanzi.
8. Uma ithreyi lokufafaza liphakeme kunezansi komugqa oseduze noma lingaphezu kwewebhu yepayipi lokungenisa umoya, khipha ipayipi kanye nebhuloho elinobubanzi obungaphansi kuka-1.2m, ibanga eliphakeme eliqondile phakathi kwethreyi yokufafaza kanye iwebhu ye-beam, ipayipi lokungenisa umoya, ipayipi lokudonsa amanzi kanye nebhuloho kuzohlangabezana nezidingo.
9. Lapho ububanzi be-boam, ipayipi lokungenisa umoya, ipayipi lokudonsa kanye nebhuloho kungaphezu kuka-1.2m, okungeziweisifafazi izofakwa ngaphansi kwewebhu yayo.
10. Uma isifafazi sifakiwe eduze nendawo engafinyeleli phezulu, ibanga elivundlile kanye nebanga eliphansi eliqondile phakathi kwesifafazi kanye nokwahlukanisa kuzohlangabezana nezimfuneko.
11. Ibanga phakathi kwethreyi le-splash ye-I-ESFRisifafazi futhi ipuleti eliphezulu kufanele libe ngu-150 mm ~ 360 mm. Ibanga eliphakathi kwethreyi le-splash yesifafazi se-vertical early suppression fast response (ESFR) kanye nepuleti eliphezulu lizoba ngu-100mm~150mm.
12 Ukuma okuhlobene kwesithiyo ku-top plate kanye nanoma yisiphiisifafazi izokwenza ibanga eliqondile (H) ukusuka ku-isifafazi ukuya phansi kwesithiyo kanye nebanga elivundlile (L) ukusuka onqenqemeni lwesithiyo kuhlangabezana nezidingo. Lapho izimfuneko zingenakufinyelelwa, enye yalezi zidingo ezilandelayo izohlangatshezwana nayo.
1) Lapho ububanzi besithiyo esiqinile epuletini eliphezulu bungadluli ku-0.6m, izifafaza zizofakwa ezinhlangothini zombili zesithiyo, futhi ibanga elivundlile phakathi kwezifafazi ezinhlangothini zombili futhi isithiyo akufanele sibe ngaphezu kwesigamu. yesikhala esidingekayo sokufafaza.
2) Ezingxenyeni zesakhiwo ezingaqinile ku-top plate, ibanga elivundlile phakathi komshini wokufafaza kanye nonqenqema oluseceleni lwengxenye akumele libe ngaphansi kuka-0.3m.
5.2.13 Ibanga phakathi kwempendulo esheshayo yokucindezela (ESFR)isifafazi kanye nezithiyo ngaphansiisifafazi izohlangabezana nezidingo. Lapho izidingo zingenakufinyelelwa, ububanzi kanye nesimo sezithiyo ngaphansi kweisifafazi izohlangabezana nezidingo.
14. Izithiyo ngaphansi kokuphendula okusheshayo kokucindezela okuqondile (ESFR)isifafazi ingashaywa indiva lapho ihlangabezana nanoma yiziphi izidingo ezilandelayo.
1) Ububanzi noma ububanzi be-chord engezansi yobakaki ophahleni noma i-truss enesisu esisobala akumele ibe ngaphezu kuka-10cm.
2) Ububanzi noma ububanzi bezinye izingxenye zesakhiwo ngasinye akumele zibe ngaphezu kuka-10cm.
3) Ububanzi noma ububanzi bamapayipi ngamunye noma iziqu akumele bube ngaphezu kuka-10cm, noma ububanzi obuphelele bamapayipi amaningi noma ama-trunk akumele bube ngaphezu kuka-10cm.
