Zvichienderana nemaparamita e mold uye zvinodiwa zvemaitiro zvinopihwa nemushandisi (yepamusoro uye yepasi mold uye yepakati mold inofanirwa kudziirwa kusvika 170 ° C panguva imwe chete), uye pamwe chete nemapoinzi akakosha.mold tembiricha controllerSarudzo inowanikwa mumhedzisiro yekutsvaga, zvinotevera zvinokurudzirwa simba uye pombi yemafuta kusarudzwa kune maviri mold tembiricha anodzora:
I. Mold Temperature ControllerPower Selection
1. Heating Power Calculation
Simba rekudziya rinofanirwa kuverengerwa zvichienderana nehuremu hwekuumbwa, kusiyana kwetembiricha, huwandu hwekupisa, uye nguva yekudziya. Formula ndeiyi:
KW = W × Δt × C / (860 × T)
W: Huremu hweMold (kg) (1.5t imwe neimwe yekumusoro uye yakaderera mold = 1500kg, 3t yepakati mold = 3000kg)
Δt: Kusiyanisa kwekushisa (170 ° C - 20 ° C ambient tembiricha = 150 ° C)
C: Yakananga kupisa kugona (0.11 yesimbi molds)
T: Nguva yekupisa (inotora 1 awa)
Kuverengera Muenzaniso:
Simba reimwemold tembiricha controllerzvepamusoro nepamusoro molds:
KW = (1500 × 2) × 150 × 0.11 / (860 × 1) ≈ 57.6 kW (tichifunga nezvekurasikirwa kwekupisa, 20% redundancy inokurudzirwa, saka 70 kW inosarudzwa).
Middle die tembiricha controller simba:
kW = 3000 × 150 × 0.11 / (860 × 1) ≈ 57.6 kW (yakafanana ne70 kW).
Manufacturer Recommendation:
Huru-tonnage molds (semuenzaniso, 3-ton yepakati molds) inoda simba repamusoro kuti ive nechokwadi chekupisa nguva. Tarisa kune kumisikidzwa kwema molds mumashini anofa-casting anopfuura mazana masere matani (24 kW/mold). Nekudaro, mushandisi anoda kupisa kwese, saka kuverenga kwakadzama kunodiwa.
2. Temperature Control Kururama uye Kugadzikana
Iyo die-casting process inoda kudzikamisa tembiricha mukati ± 1°C. Iyo PID kana PLC yekudzora sisitimu ine yakakwirira-chaiyo tembiricha sensor inodiwa.
Dual-circuit kana akawanda-circuit madhizaini anonyanya kukodzera mold ane akawanda machaneli emafuta kuti ave nechokwadi chekufanana kwekushisa.
II. Oiri Pombi Sarudzo
1. Kuyerera uye Kudzvinyirira Zvinodiwa
Kuyerera kwekuverenga: Iyo yakazara mafuta chiteshi vhoriyamu uye kutenderera kumhanya kunofanirwa kusangana. Vhoriyamu yeimwe nzira yemafuta (dhayamita 19mm = 1.9cm, kureba 11m = 1100cm):
V = πr² × L = 3.14 × (0.95)² × 1100 ≈ 3125cm³ = 3.125L/chiteshi.
Yese yekuyerera mwero wepamusoro / yepasi molds: 8 nzira dzemafuta, 4 inlet uye 4 yekubuda, yakazara vhoriyamu 25L. Inokurudzirwa kutenderera kweyero ≥ 100L / min inokurudzirwa (kuve nechokwadi chekutsinhanisa kupisa nekukurumidza).
Flow rate yepakati mold: Maverengero akafanana anodiwa, anoda ≥ 80L/min.
Pressure zvinodiwa:
Marefu uye akawanda-matavi emafuta machani anoda yakakwira-pressure pombi (≥ 4bar) kukunda kuramba. Iyo magineti drive pombi (yakakwira-inodzivirira uye ine backflow rutsigiro) inokurudzirwa.
2. Oil Pump Type uye Hunhu
Fixed-flow pumps: Chimiro chakareruka, chakakodzera kugadzikana kwekuyerera zvinodiwa; mapombi anochinja-chinja: Anochengetedza magetsi asi anodhura, akakodzera kushanduka-shanduka kuyerera.
Material: High-temperature thermal oil (kusvika ku350 ° C) inoda muviri wepombi yesimbi isina tsvina uye zvisimbiso zvinodzivirira zvakanyanya (zvakadai sefluororubber).
III. Comprehensive Selection Recommendations
Mold Temperature ControllerConfiguration:
Pamusoro/PazasiMold Temperature Controller: 70kW kupisa simba, 100L/min kuyerera mwero, 4 bar kudzvanywa, maviri-yedunhu dhizaini.
PakatiMold Temperature Controller: 70kW kupisa simba, 80L/min kuyerera mwero, 4 bar kudzvanywa, imwe-yedunhu dhizaini (maseketi akawanda anodiwa kune tembiricha zoning).
Zvimwe Zvimiro:
Air-blowing uye mafuta-kudzorera basa (inodzorera mafuta ekupisa panguva yekuchinja mold).
PLC kutonga, inotsigira tembiricha curve programming uye kukanganisa matanda.
Kuchengetedza uye Kugona Kwesimba:
Kudzivirirwa kwekupisa, yakaderera-mvura alarm, uye mamwe maficha ekuchengetedza.
Eneji-inoponesa inoshanduka frequency pombi dhizaini inoderedza kushandiswa kwesimba kwenguva refu.
IV. Zvekungwaririra
Heat transfer fluid: High-temperature synthetic oil (yakadai sebiphenyl-diphenyl ether musanganiswa). Shandura nguva dzose (gore rinokurudzirwa).
Pipe Connections: Shandisa 19mm dhayamita yesimbi spiral tubing kuderedza kupisa.
Kana iwe uchida kuziva zvakawanda nezvechigadzirwa chedu, ndapotataura nesu!
