Codsiyada:

Tijaabada heerka socodka dhalaalka ee YYP-400E waa qalab lagu go'aamiyo waxqabadka socodka ee polymers-ka balaastikada ah heerkulka sare iyadoo la raacayo habka tijaabada ee lagu qeexay GB3682-2018. Waxaa loo isticmaalaa in lagu cabbiro heerka socodka dhalaalka ee polymers-ka sida polyethylene, polypropylene, polyoxymethylene, resin ABS, polycarbonate, naylon, iyo fluoroplastics heerkulka sare. Waxay khuseysaa wax soo saarka iyo cilmi-baarista warshadaha, shirkadaha iyo hay'adaha cilmi-baarista sayniska.

2. Xoogga Tijaabada Caadiga ah (Sideed Heer)

Heerka 1aad: 0.325 kg = (Usha Bistooladda + Digsiga Miisaanka + Gacanta Dahaarka leh + Miisaanka Lambarka 1aad) = 3.187 N

Heerka 2aad: 1.200 kg = (0.325 + Lambarka 2aad 0.875 Miisaanka) = 11.77 N

Heerka 3aad: 2.160 kg = (0.325 + Lambarka 3aad 1.835 Miisaanka) = 21.18 N

Heerka 4aad: 3.800 kg = (0.325 + Lambarka 4aad 3.475 Miisaanka) = 37.26 N

Heerka 5: 5.000 kg = (0.325 + Lambarka 5 4.675 Miisaanka) = 49.03 N

Heerka 6aad: 10.000 kg = (0.325 + Lambarka 5aad 4.675 Miisaanka + Lambarka 6aad 5.000 Miisaanka) = 98.07 N

Heerka 7aad: 12,000 kg = (0.325 + Lambarka 5aad 4.675 Miisaanka + Lambarka 6aad 5.000 + Lambarka 7aad 2.500 Miisaanka) = 122.58 N

Heerka 8aad: 21.600 kg = (0.325 + Lambarka 2 0.875 Miisaanka + Lambarka 3 1.835 + Lambarka 4 3.475 + Lambarka 5 4.675 + Lambarka 6 5.000 + Lambarka 7 2.500 + Lambarka 8 2.915 Miisaanka) = 211.82 N

Khaladka qaraabada ah ee miisaanka waa ≤ 0.5%.

3. Heerkulka Kala Duwan: 50°C ~ 300°C

4. Xasiloonida Heerkulka: ±0.5°C

5. Korontada: 220V ± 10%, 50Hz

6. Xaaladaha Deegaanka Shaqada:

Heerkulka Deegaanka: 10°C ilaa 40°C;

Qoyaanka Qaraabada ah: 30% ilaa 80%;

Ma jiro wax dhexdhexaad ah oo mix ah oo ku xeeran;

Ma jiro gudbis Hawo oo xooggan;

Ka xor ah gariir ama faragelin xoog leh oo ku saabsan goobta birlabta.

7. Cabbirka Qalabka: 280 mm × 350 mm × 600 mm (Dhererka × Ballaca ×Dhererka)

Mabda'a Qaab-dhismeedka iyo Shaqada:

Tijaabiyaha heerka socodka dhalaalka waa nooc ka mid ah mitirka balaastikada ah ee la soo saaray. Marka la eego xaaladaha heerkulka ee la cayimay, muunadda la tijaabinayo waxaa lagu kululeeyaa xaalad dhalaal ah foorno heerkul sare leh. Muunadda dhalaalaysa waxaa markaa laga soo saaraa god yar oo dhexroor cayiman leh iyadoo la saarayo culays miisaan la cayimay. Soo saarista balaastikada ee shirkadaha warshadaha iyo cilmi-baarista hay'adaha cilmi-baarista sayniska, "heerka socodka dhalaalka (cufka)" waxaa badanaa loo isticmaalaa in lagu matalo dareeraha, dheellitirka iyo sifooyinka kale ee jireed ee walxaha polymer-ka ee xaaladda dhalaalaysa. Tusmada dhalaalka ee loogu yeero waxay tilmaamaysaa miisaanka celceliska qayb kasta oo ka mid ah muunadda la soo saaray ee loo beddelay xaddiga soo saarista 10 daqiiqo gudahood.

Qalabka heerka socodka dhalaalka (cufnaanta) waxaa lagu tilmaamay MFR, iyadoo cutubku yahay: garaam 10kii daqiiqoba (g/daqiiqo).

Qaacidadu waa:

MFR(θ, mnom) = tref. m / t

Halkee: θ —- heerkulka tijaabada

Mnom— - culayska magacaaban (Kg)

m —- celceliska cufka goynta, g

tref —- waqtiga tixraaca (10 daqiiqo), S (600s)

t ——- waqtiga kala-goynta, s

Tusaale:

Koox muunado balaastig ah ayaa la jaray 30kii ilbiriqsiba mar, natiijooyinka cufka qayb kastana waxay ahaayeen: 0.0816 garaam, 0.0862 garaam, 0.0815 garaam, 0.0895 garaam, 0.0825 garaam.

Qiimaha celceliska m = (0.0816 + 0.0862 + 0.0815 + 0.0895 + 0.0825) ÷ 5 = 0.0843 (garaam)

Ku beddel qaacidada: MFR = 600 × 0.0843 / 30 = 1.686 (garaam 10 daqiiqo kasta)
