Kuwunika kwaukadaulo ndi mfundo zazikuluzikulu za uinjiniya pakuyika kwa eccentric reducer mu pampu yamoto
1.Configuration specifications of the outlet pipeline parts
Malinga ndi zofunikira za GB50261 "Code for Construction and Acceptance of Automatic Sprinkler System":
Kukonzekera kwa Chigawo Chachikulu:
● Chovala chowongolera (kapena valavu yogwiritsira ntchito pampu yambiri) chiyenera kukhazikitsidwa kuti chiteteze kubwerera kwapakati
● Valavu yoyendetsera ndiyofunika kuti pakhale kayendedwe ka kayendedwe kake
● Kuyang'anitsitsa kawiri kayezedwe kake kantchito ndi kuwunika kwapaipi yapaipi yayikulu yadongosolo
Zofunikira pakuwunika kwa Pressure:
● Choyezera kuthamanga chiyenera kukhala ndi chipangizo chotchinga (diaphragm buffer ndiyofunika)
● Pulagi valavu yoikidwa kutsogolo kwa chipangizo chosungirako kuti chisamalidwe mosavuta
● Kuthamanga kwazitsulo: 2.0-2.5 nthawi yogwira ntchito ya dongosolo
2. Malangizo oyika pazida zowongolera madzimadzi
Zofunikira pamayendedwe:
● Mavavu owunikira / ma valve owongolera magwiridwe antchito ambiri akuyenera kugwirizana kwambiri ndi komwe madzi akuyenda
● Kulumikizana kwa flange kumalimbikitsidwa kuti kuwonetsetse kulimba
Tsatanetsatane wa kukhazikitsa Pressure gauge:
● Zida zosagwira dzimbiri (304 zitsulo zosapanga dzimbiri kapena aloyi yamkuwa) ziyenera kugwiritsidwa ntchito pazida zotchingira.
● Kutalika kwa valavu ya pulagi kuyenera kukhala 1.2-1.5m kuchokera pansi
3.Optimization chiwembu cha kuyamwa chitoliro dongosolo
Zosefera zida zosefera:
● Chitoliro choyamwa chiyenera kukhala ndi fyuluta yadengu (pore size≤3mm)
● Fyulutayo iyenera kukhala ndi chipangizo cha alamu chosiyana
Zapangidwira kuti zisamavutike kukonza:
● Zosefera ziyenera kukhala ndi payipi yodutsa ndi mawonekedwe oyeretsera mwachangu
● Kupanga zosefera zomwe zingachotsedwe ndizovomerezeka
4.Kuteteza miyeso yamakhalidwe a hydraulic
Kusankha kwa Eccentric reducer:
● Zochepetsera zokhazikika ziyenera kugwiritsidwa ntchito (malinga ndi SH/T 3406)
● Mbali ya chochepetsera iyenera kukhala ≤8 ° kuti ateteze kusintha kwadzidzidzi kukana kwanuko
Kukhathamiritsa Kwakuyenda:
● Kutalika kwa gawo la chitoliro chowongoka musanayambe ndi pambuyo pa chotsitsacho chiyenera kukhala ≥ 5 nthawi ya chitoliro
● Mayesero a CFD akulimbikitsidwa kuti atsimikizire kugawa kwa mlingo wothamanga
5.Kusamala kuti polojekiti ichitike
Kuyeza kupsinjika:
● Mayeso a kuthamanga kwa dongosolo ayenera kukhala 1.5 nthawi zogwira ntchito
● Nthawi yogwira si yochepera 2 hours
Flushing Protocol:
● Pickling passivation ayenera kuchitidwa pamaso unsembe dongosolo
● Kuthamanga kwa madzi othamanga kuyenera kukhala ≥ 1.5m / s
Zoyenera Kulandila:
● Mulingo wolondola wa sikelo yoyezera kuthamanga sikuyenera kutsika kuposa 1.6
● Kuthamanga kwa kusiyana kwa fyuluta kuyenera kukhala ≤ 0.02MPa
6.Dongosolo lodziwika bwinoli laphatikizidwa mu "Technical Specifications for Fire Water Supply and Fire Hydrant Systems" GB50974, ndipo tikulimbikitsidwa kuchita kusanthula kwa HAZOP kuphatikiza ndi ma projekiti apadera, poyang'ana paziwopsezo zotsatirazi:
● Kuopsa kwa backflow wa zofalitsa chifukwa cha kulephera kwa ma valve cheke
● Kuopsa kwa kulephera kwa madzi chifukwa cha zosefera zotsekeka
● Kuopsa kogwira ntchito mopitirira muyeso chifukwa cha kulephera kwa kupima mphamvu
● Kuopsa kwa hydraulic shock chifukwa cha kuika molakwika zochepetsera
Ndikoyenera kutengera dongosolo loyang'anira digito, kukonza masensa othamanga, owunikira othamanga ndi osanthula ma vibration, ndikukhazikitsa njira yoyang'anira chipinda cha pampu yamoto kuti akwaniritse kuwunika kwanthawi yeniyeni ndi chenjezo lolakwika.
