Ho ipapisitsoe le liparamente tsa hlobo le litlhoko tsa ts'ebetso tse fanoeng ke mosebelisi (mofuta o kaholimo le o tlase le hlobo e bohareng e tlameha ho futhumatsoa ho 170 ° C ka nako e le 'ngoe), hammoho le lintlha tsa bohlokoaselaoli sa mocheso oa hlobokhetho e fumanoang liphethong tsa lipatlisiso, tse latelang li khothaletsoa khetho ea matla le pompo ea oli bakeng sa lilaoli tse peli tsa mocheso oa hlobo:
I. Mold Temperature ControllerKhetho ea Matla
1. Ho Heating Power Calculation
Matla a ho futhumatsa a tlameha ho baloa ho latela boima ba hlobo, phapang ea mocheso, matla a khethehileng a mocheso, le nako ea ho futhumatsa. Foromo ke:
KW = W × Δt × C / (860 × T)
W: Boima ba hlobo (kg) (1.5t ka 'ngoe bakeng sa hlobo e ka holimo le e ka tlaase = 1500kg, 3t bakeng sa hlobo e bohareng = 3000kg)
Δt: Phapang ea mocheso (170°C - 20°C mocheso o teng = 150°C)
C: Matla a khethehileng a mocheso (0.11 bakeng sa hlobo ea tšepe)
T: Nako ea ho futhumatsa (ho nka hora e le 'ngoe)
Palo Mohlala:
Matla a le mongselaoli sa mocheso oa hlobobakeng sa hlobo e ka holimo le e ka tlaase:
KW = (1500 × 2) × 150 × 0.11 / (860 × 1) ≈ 57.6 kW (ho nahanoa ka tahlehelo ea mocheso, ho khothalletsoa ho fokotsa 20%, kahoo 70 kW e khethoa).
Matla a taolo ea mocheso oa bohareng:
kW = 3000 × 150 × 0.11 / (860 × 1) ≈ 57,6 kW (e tšoanang le 70 kW).
Keletso ea Moetsi:
Mefuta e meholo ea lithane tse kholo (mohlala, hlobo e bohareng ea lithane tse 3) e hloka matla a phahameng ho netefatsa nako ea ho futhumatsa pele. Sheba tlhophiso ea liforomo ka har'a mochini oa ho lahla lithane tse fetang 800 (24 kW/mold). Leha ho le joalo, mosebelisi o hloka ho futhumatsa ka kakaretso, ka hona ho hlokahala lipalo tse felletseng.
2. Ho Nepaha ha Taolo ea Mocheso le Botsitso
Ts'ebetso ea "die-casting" e hloka ho nepahala ha taolo ea mocheso ka har'a ± 1°C. Hoa hlokahala sistimi ea taolo ea PID kapa PLC e nang le sensor e nepahetseng haholo ea mocheso.
Meetso ea li-circuit tse peli kapa tse ngata li loketse liforomo tse nang le likanale tse ngata tsa oli ho netefatsa ho ts'oana ha mocheso.
II. Khetho ea Pompo ea Oli
1. Litlhoko tsa Phallo le Khatello
Palo ea phallo: Bophahamo ba kanale ea oli kaofela le lebelo la ho potoloha li tlameha ho finyelloa. Bophahamo ba mocha o le mong oa oli (bophara ba 19mm = 1.9cm, bolelele ba 11m = 1100cm):
V = πr² × L = 3.14 × (0.95)² × 1100 ≈ 3125cm³ = 3.125L/kanale.
Kakaretso ea sekhahla sa ho phalla ha liforomo tse ka holimo / tse ka tlaase: likanale tsa oli tse 8, 4 inlet le 4 outlet, kakaretso ea 25L. Sekhahla sa phallo e khothalletsoang ≥ 100L / min e khothalletsoa (ho netefatsa phapanyetsano ea mocheso ka potlako).
Sekhahla sa phallo bakeng sa hlobo e bohareng: Ho hlokahala lipalo tse tšoanang, tse hlokang ≥ 80L / min.
Litlhoko tsa khatello:
Likanale tsa oli tse telele le tse nang le makala a mangata li hloka pompo ea khatello e phahameng (≥ 4bar) ho hlola khanyetso. Ho kgothaletswa pompo ea ho khanna magnetic (mocheso o phahameng le o nang le tšehetso ea ho khutlela morao).
2. Mofuta oa Pompo ea Oli le Litšobotsi
Lipompompe tse tsitsitseng: Sebopeho se bonolo, se loketseng litlhoko tse tsitsitseng tsa phallo; lipompo tsa phallo e feto-fetohang: Li boloka matla empa li bitsa chelete e ngata, tse loketseng maemo a phallo e feto-fetohang.
Boitsebiso: Oli ea mocheso o phahameng oa mocheso (ho fihlela ho 350 ° C) e hloka 'mele oa pompo ea tšepe e sa hloekang le litiiso tse hanyetsanang le mocheso o phahameng (joaloka fluororubber).
III. Litlhahiso tse Felletseng tsa Khetho
Mold Temperature ControllerTlhophiso:
Holimo/Ka tlaseMold Temperature Controller: Matla a ho futhumatsa a 70kW, sekhahla sa phallo ea 100L / min, khatello ea li-bar tse 4, moralo oa lipotoloho tse peli.
HareMold Temperature Controller: Matla a ho futhumatsa a 70kW, sekhahla sa phallo ea 80L / min, khatello ea li-bar tse 4, moralo oa potoloho e le 'ngoe (ho hlokahala lipotoloho tse ngata bakeng sa libaka tsa mocheso).
Likarolo tse Eketsehileng:
Ts'ebetso ea ho foka moea le ho khutlisa oli (e khutlisa oli e chesang nakong ea liphetoho tsa hlobo).
Taolo ea PLC, e ts'ehetsa mananeo a curve ea mocheso le ho rema lifate.
Polokeho le Matla a Matla:
Tšireletso ea mocheso o feteletseng, alamo ea metsi a tlase, le likarolo tse ling tsa polokeho.
Moralo oa pompo o bolokang matla o fapaneng o fokotsa tšebeliso ea nako e telele ea matla.
IV. Mehato ya tlhokomelo
Mokelikeli o fetisang mocheso: Oli e entsoeng ka mocheso o phahameng (joaloka motsoako oa biphenyl-diphenyl ether). Fetola khafetsa (ho khothaletsoa ka selemo).
Khokahano ea Liphaephe: Sebelisa 19mm bophara ba tšepe spiral tubing ho fokotsa tahlehelo ea mocheso.
Haeba u batla ho tseba haholoanyane ka sehlahisoa sa rona, ka kopoiteanye le rona!
