Bisa ga mold sigogi da aiwatar da bukatun bayar da mai amfani (mafi girma da ƙananan molds da cibiyar mold dole ne a mai tsanani zuwa 170 ° C lokaci guda), da kuma a hade tare da key maki domin.mold zazzabi mai kulazaɓin da aka samo a cikin sakamakon binciken, ana bada shawarar wutar lantarki da zaɓin famfo mai don masu kula da zafin jiki guda biyu:
I. Mai Kula da Zazzabi MoldZaɓin Wuta
1. Ƙididdigar Ƙarfin wutar lantarki
Dole ne a ƙididdige ƙarfin dumama bisa nauyin ƙira, bambancin zafin jiki, ƙayyadaddun ƙarfin zafi, da lokacin dumama. Tsarin tsari shine:
KW = W × Δt × C / (860 × T)
W: Nauyin Mold (kg) (1.5t kowanne don babba da ƙananan ƙira = 1500kg, 3t don ƙirar tsakiya = 3000kg)
Δt: Bambancin yanayin zafi (170°C - 20°C zazzabi na yanayi = 150°C)
C: Ƙarfin zafi na musamman (0.11 don ƙirar ƙarfe)
T: Lokacin zafi (yana ɗaukar awa 1)
Misalin Lissafi:
Ƙarfin guda ɗayamold zazzabi mai kulaga na sama da na ƙasa molds:
KW = (1500 × 2) × 150 × 0.11 / (860 × 1) ≈ 57.6 kW (la'akari da asarar zafi, an ba da shawarar sakewa 20%, don haka an zaɓi 70 kW).
Ƙarfin zafin mutun na tsakiya:
kW = 3000 × 150 × 0.11 / (860 × 1) ≈ 57.6 kW (daidai da 70 kW).
Shawarar Mai ƙira:
Manya-manyan gyare-gyare (misali, gyare-gyare na tsakiya 3-ton) suna buƙatar babban iko don tabbatar da lokacin preheating. Koma zuwa tsarin gyare-gyare a cikin injunan simintin simintin mutuwa sama da tan 800 (24 kW/mold). Koyaya, mai amfani yana buƙatar dumama dumama, don haka ana buƙatar cikakken lissafi.
2. Daidaitawar Kula da Zazzabi da Kwanciyar hankali
Tsarin simintin mutuwa yana buƙatar daidaiton sarrafa zafin jiki tsakanin ±1°C. Ana buƙatar tsarin sarrafa PID ko PLC sanye take da madaidaicin firikwensin zafin jiki.
Zane-zane biyu-dawafi ko ƙirar kewayawa da yawa sun fi dacewa da ƙirar ƙira tare da tashoshi mai yawa don tabbatar da daidaiton zafin jiki.
II. Zabin famfo mai
1. Bukatun Gudun Guda da Matsi
Lissafin gudana: jimlar ƙarar tashar mai da saurin zagayawa dole ne a hadu. Girman tashar mai guda ɗaya (diamita 19mm = 1.9cm, tsayin 11m = 1100cm):
V = πr² × L = 3.14 × (0.95)² × 1100 ≈ 3125cm³ = 3.125L/tashar.
Jimlar yawan kwararar ƙira na sama/ƙasa: Tashoshin mai 8, mashigai 4 da fitarwa 4, jimlar ƙarar 25L. Ana ba da shawarar ƙimar kwararar wurare dabam dabam ≥ 100L/min (don tabbatar da saurin musayar zafi).
Matsakaicin kwarara don ƙirar tsakiya: Ana buƙatar ƙididdiga iri ɗaya, ana buƙatar ≥ 80L / min.
Bukatun matsin lamba:
Tashoshin mai mai tsayi da yawa da yawa suna buƙatar famfo mai ƙarfi (≥ 4bar) don shawo kan juriya. Ana ba da shawarar famfo injin maganadisu (mai juriya mai zafi kuma tare da goyan bayan baya)
2. Nau'in Pump Na Mai da Halaye
Kafaffen famfo mai gudana: Tsarin sauƙi, dacewa da buƙatun buƙatun kwarara; famfo mai canzawa: ceton makamashi amma mai tsada, dace da yanayin jujjuyawar yanayi.
Material: Mai zafi mai zafi (har zuwa 350 ° C) yana buƙatar jikin famfo na bakin karfe da hatimin juriya mai zafi (kamar fluororubber).
III. Cikakken Shawarwari na Zaɓi
Mai Kula da Zazzabi MoldTsari:
Sama/ƘasaMai Kula da Zazzabi Mold: 70kW dumama ikon, 100L / min kwarara kudi, 4 mashaya matsa lamba, dual-circuit zane.
TsakiyaMai Kula da Zazzabi Mold: 70kW dumama ikon, 80L / min kwarara kudi, 4 mashaya matsa lamba, daya-circuit zane (yawan da'ira da ake bukata domin zafin zoning).
Ƙarin Halaye:
Ayyukan busa iska da dawo da mai (yana dawo da mai mai zafi yayin canjin ƙira).
Ikon PLC, yana goyan bayan shirye-shiryen lanƙwan zafin jiki da kuskuren shiga.
Aminci da Ingantaccen Makamashi:
Kariyar zafin jiki, ƙaramar ƙararrawar ruwa, da sauran fasalulluka na aminci.
Ƙirar mitar famfo mai saurin ceton makamashi yana rage yawan amfani da makamashi na dogon lokaci.
IV. Matakan kariya
Ruwan canja wurin zafi: Man roba mai zafi mai zafi (kamar cakuda ether biphenyl-diphenyl). Canja akai-akai (an bada shawarar kowace shekara).
Haɗin Bututu: Yi amfani da bututu mai karkace diamita na 19mm don rage asarar zafi.
Idan kuna son ƙarin sani game da samfuranmu, don Allahtuntube mu!
