Kutengera magawo a nkhungu ndi zofunikira zomwe zimaperekedwa ndi wogwiritsa ntchito (zoumba zam'mwamba ndi zam'munsi ndi nkhungu yapakati iyenera kutenthedwa mpaka 170 ° C nthawi imodzi), komanso kuphatikiza ndi mfundo zazikuluzikulu.chowongolera kutentha kwa nkhungukusankha komwe kumapezeka muzotsatira zakusaka, zotsatirazi ndizomwe zikulimbikitsidwa kusankha mphamvu ndi pampu yamafuta kwa owongolera kutentha kwa nkhungu:
I. Mold Temperature ControllerKusankha Mphamvu
1. Kuwerengera Mphamvu Kutentha
Mphamvu yowotcha iyenera kuwerengedwa motengera kulemera kwa nkhungu, kusiyana kwa kutentha, mphamvu ya kutentha kwapadera, ndi nthawi yotentha. Fomula ndi:
KW = W × Δt × C / (860 × T)
W: Kulemera kwa nkhungu (kg) (1.5t iliyonse yamitundu yapamwamba ndi yapansi = 1500kg, 3t yapakati nkhungu = 3000kg)
Δt: Kusiyana kwa kutentha (170 ° C - 20 ° C yozungulira kutentha = 150 ° C)
C: Kutentha kwapadera (0.11 kwa nkhungu zachitsulo)
T: Nthawi yotentha (kutengera ola la 1)
Chitsanzo chowerengera:
Mphamvu ya singlechowongolera kutentha kwa nkhungukwa nkhungu zapamwamba ndi zapansi:
KW = (1500 × 2) × 150 × 0.11 / (860 × 1) ≈ 57.6 kW (poganizira kutaya kutentha, 20% redundancy ikulimbikitsidwa, kotero 70 kW imasankhidwa).
Mphamvu yowongolera kutentha kwapakati:
kW = 3000 × 150 × 0,11 / (860 × 1) ≈ 57,6 kW (mofanana ndi 70 kW).
Malangizo Opanga:
Zoumba zokhala ndi matani akulu (mwachitsanzo, matani atatu apakati) amafunikira mphamvu zapamwamba kuti zitsimikizire nthawi yotentha. Onani masinthidwe a nkhungu m'makina oponyera matani opitilira 800 (24 kW / nkhungu). Komabe, wogwiritsa ntchito amafuna kutentha kwathunthu, kotero kuwerengera kokwanira kumafunika.
2. Kuwongolera Kutentha Kulondola ndi Kukhazikika
Njira yopangira kufa imafuna kuwongolera kutentha mkati mwa ± 1 ° C. Dongosolo lowongolera la PID kapena PLC lomwe lili ndi sensor yolondola kwambiri ya kutentha ndikofunikira.
Mapangidwe amitundu iwiri kapena ma circuit ambiri ndi oyenera kuumba okhala ndi njira zingapo zamafuta kuti zitsimikizire kutentha.
II. Kusankha Pampu ya Mafuta
1. Zofunikira za Kuyenda ndi Kupanikizika
Kuwerengera kwamayendedwe: Kuchuluka kwa njira yamafuta ndi liwiro lozungulira liyenera kukwaniritsidwa. Kuchuluka kwa njira imodzi yamafuta (m'mimba mwake 19mm = 1.9cm, kutalika 11m = 1100cm):
V = πr² × L = 3.14 × (0.95)² × 1100 ≈ 3125cm³ = 3.125L/channel.
Kuthamanga konse kwa nkhungu zapamwamba / zotsika: 8 ngalande zamafuta, zolowera 4 zolowera ndi 4, voliyumu yonse 25L. Kuthamanga kwa kayendedwe kovomerezeka ≥ 100L / min ndikulimbikitsidwa (kuonetsetsa kutentha kwachangu).
Kuthamanga kwa nkhungu yapakati: Kuwerengera kofanana kumafunika, kumafuna ≥ 80L / min.
Zofunikira za Pressure:
Njira zamafuta zazitali komanso zamitundu yambiri zimafunikira pampu yothamanga kwambiri (≥ 4bar) kuti igonjetse kukana. Pampu yoyendetsa maginito (yopanda kutentha kwambiri komanso yothandizidwa ndi backflow) ikulimbikitsidwa.
2. Mtundu wa Pampu ya Mafuta ndi Makhalidwe
Mapampu oyenda osasunthika: Mapangidwe osavuta, oyenera oyenda okhazikika; mapampu oyenda mosiyanasiyana: Opulumutsa mphamvu koma okwera mtengo, oyenera kusinthasintha kwamayendedwe.
Zida: Mafuta otentha kwambiri (mpaka 350 ° C) amafunikira thupi la mpope lachitsulo chosapanga dzimbiri komanso zisindikizo zosagwirizana ndi kutentha (monga fluororubber).
III. Zosankha Zokwanira Zokwanira
Mold Temperature ControllerKusintha:
Pamwamba/PansiMold Temperature Controller: 70kW Kutentha mphamvu, 100L/mphindi otaya mlingo, 4 bala kuthamanga, wapawiri-dera kapangidwe.
PakatiMold Temperature Controller: 70kW Kutentha mphamvu, 80L/mphindi otaya mlingo, 4 mipiringidzo kuthamanga, single-dera kamangidwe (mabwalo angapo amafunikira pa kugawa kutentha).
Zowonjezera:
Kuwombera mpweya ndi kubwezeretsa mafuta (kubwezeretsanso mafuta otentha panthawi ya kusintha kwa nkhungu).
Kuwongolera kwa PLC, kumathandizira kukonza mapindikidwe a kutentha ndi kudula mitengo.
Chitetezo ndi Mphamvu Mwachangu:
Chitetezo cha kutentha kwambiri, alamu yamadzi otsika, ndi zina zachitetezo.
Mapangidwe a pampu opulumutsa mphamvu amachepetsa kugwiritsa ntchito mphamvu kwanthawi yayitali.
IV. Njira zodzitetezera
Madzi otengera kutentha: Mafuta opangira kutentha kwambiri (monga osakaniza a biphenyl-diphenyl ether). Sinthani nthawi zonse (zovomerezeka pachaka).
Kulumikizira mapaipi: Gwiritsani ntchito machubu achitsulo ozungulira 19mm kuti muchepetse kutentha.
Ngati mukufuna kudziwa zambiri za mankhwala athu, chondeLumikizanani nafe!
