Kwaliti Kontrol Bilong Pis Fid Prodaksen Lain?

Kwaliti kontrol bilong wanpela twin-skru pis fid prodaksen lain (em i wok bilong wokim ol ikwipmen bilong prodaksen lain) i stap long meksua olsem pefomens i stap gut, straksel reliabiliti, proses inap long senis, na bihainim ol indastri standet na sefti regulesen bilong fid prodaksen. Dispela proses i mas karamapim olgeta proses bilong disain, prosesim ol komponen, bungim na stretim ol hevi, olsem:

Disain em i as bilong kwaliti bilong ol ikwipmen, we i mas bung wantaim ol pasin bilong teknoloji bilong kamapim kaikai bilong pis long lukim olsem ol ikwipmen paramita i stret wantaim ol samting ol i laikim long kamapim.
Pefomens paramita disain verifikesen
Painimaut ol bikpela samting bilong twin-skru ekstruda bihainim mak bilong prodaksen kapasiti (olsem 1-10 ton/aua) na kain kaikai (olsem setelmen, floting, na ol liklik hap):
Diamita bilong skru (planti taim 30-150mm), 'aspect ratio' (L/D=20-40): Em i mas inapim ol samting bilong miksim, katim, na mekim i kamap bikpela insait long baret;
Namba bilong ol 'barrel segments' (3-6 'segments'): Mekim gut olsem ol i ken stretim tempereja na presa long ol 'segments' long inapim ol 'maturation' rikwaemen bilong ol narapela narapela fomulasen;
Spesifikasen bilong het bilong 'mold' (aperture 0.5-10mm): Em i mas karamapim sais bilong ol liklik hap bilong kaikai bilong pis, na ol hul bilong 'mold' i mas stap wankain.

Rot bilong sekim: O yu ken lukluk long ol data bilong prodaksen long ol wankain divais bilong abrusim ol hevi long disain.
Struktural reliabiliti disain
Materiel seleksen bilong ol ki komponen (skru, barel, bearing): Skru i mas kamap long 'wear-resistant alloy (olsem 38CrMoAlA nitriding tritmen, hat i bikpela moa o wankain olsem HV900), na insait wol bilong barel i mas gat wanpela 'bimetallic wear-layer we i no inap long bagarap (olsem wankain olsem 3mm) long mekim sevis laip bilong en i winim o wankain olsem 10000 aua;
Transmisin sistem disain: Pawa bilong mota i mas wankain olsem prodaksen kapasiti (olsem wanpela 75-110kW mota we i mas kamap long 5-ton/aua prodaksen lain), na gia ekyuresi bilong giaboks i mas kamap long ISO level 6 o antap long abrusim nois o ovalod taim yu wok.
Sefti na Kompliens Disain
I bihainim ol standet bilong sefti bilong masin (olsem GB 12348-2008): Ol masin i mas gat wanpela baten bilong stopim taim bilong birua, kava bilong lukautim (olsem skru fid inlet, het bilong mol), na masin bilong lukautim masin (olsem 'torque sensor');
Disain bilong klinim: Ples we i pas wantaim samting i mas gutpela (Ra Less than o wankain olsem 1.6 μ m), i no gat ol kona i dai pinis, isi long klinim (olsem ol 'mold' na skru we yu ken rausim hariap), na abrusim ol 'residual material mold'.

Stretpela na ol samting bilong ol komponen i save afektim stret wok bilong ol ikwipmen, na strongpela kontrol long kwaliti bilong ol prodak i kam insait long faktori i mas kamap.
Kontrol bilong self-komponent prosesing
Lain bilong kamapim kaikai bilong pisSkru prosesing:
Ol bikpela samting bilong skelim: 'pitch error' Liklik o wankain olsem ± 0.1mm, 'outer diameter tolerance' Liklik o wankain olsem ± 0.05mm, we wanpela 'coordinate measuring instrument' i painimaut;
Tritmen bilong pes: Dip bilong 'nitride layer' em 0.3-0.5mm, na strong bilong en i wankain (long abrusim ol liklik hap we i malumalum), na wanpela 'microhardness tester' i painimaut.
Wok bilong wokim ol baret:
Raunpela bilong hul insait em i liklik long o wankain olsem 0.02mm, na 'coaxiality' em i liklik long o wankain olsem 0.05mm, na dispela i mekim na skru i gat wankain kliarens (planti taim 0.1-0.3mm, liklik tumas i save mekim ol samting i pas, na bikpela tumas i save mekim ol samting i lik);
Fletnes bilong 'segmented flange surface' em i liklik o wankain olsem 0.03mm/m long stopim paura na stim long lik bihain long ol i bungim.
Prokiumen Kontrol bilong ol Autsos Pats
Ol bikpela samting (olsem ol moto, ol 'reducer', ol 'temperature control system') ol i mas makim long ol 'brand' we ol man i save long en (olsem ol 'Siemens motors', ol 'SEW reducer'), na ol i mas kisim setifikesen bilong ol samting na ol ripot bilong sekim ol samting long faktori;
Ol samting olsem ol sensa, ol valv, na ol 'conveyor belt' i mas bihainim ol standet bilong indastri: 'temperature sensor accuracy' ± 1 digri, 'pressure sensor accuracy' ± 0.5% FS, long mekim gutpela wok painimaut long ol paramita.
Faktori inspeksen: Sampling inspeksen bilong ol hap we ol i baim (olsem 'motor insulation resistance' i winim o wankain olsem 100M Ω, nogat nois taim no-lod operesen bilong 'reducer'), na sasim ol prodak we i no -konfom.

Stretpela wok bilong bungim ol samting i makim strong na laipspan bilong wok bilong ol ikwipmen, na ol i mas bihainim gut ol spesifikasen bilong proses.
Ki asembli paramita kontrol
Twin screw meshing clearance: Tit sait kliarens bilong tupela skru i mas stap long 0.1-0.2mm (ol i mas painim long wanpela 'feeler gauge') long mekim ol samting i bruk na abrusim bagarap;
Konsentrisiti namel long barel na het bilong mol: Bihain long bungim, deviesen namel long senta bilong het bilong mol na senta bilong barel i mas liklik o wankain olsem 0.05mm long stopim strong i no wankain long taim bilong wokim ol liklik hap samting, we inap long kamapim senis long seip;
Konsentrisiti bilong transmisin sistem: Koaksialiti asua bilong mota, ridusa, na skru sef i liklik o wankain olsem 0.1mm/m (dail gej i painimaut) long abrusim bikpela guria taim yu wok.
fanksen tes
Nogat lod tes ran: Ran inap 2-pela aua, sekim tempereja bilong wanwan komponen (bearing tempereja i go antap liklik long o wankain olsem 40 digri), nois ( liklik long o wankain olsem 85dB), na spit stebiliti (deviesen liklik long o wankain olsem 2%);
Load test: Yusim ol standet fomula raw materiel (olsem 30% pis na 50% soyabin) long kamapim ol samting inap 3-pela aua, sekim:
Kwaliti bilong ol liklik hap samting: Reit bilong kwalifikesen sais bilong ol liklik hap samting I winim o wankain olsem 95%, wara i stap gut Bikpela moa o wankain olsem 30 minit;
Ol samting bilong ikwipmen: senis bilong temperaja bilong baret Liklik o wankain olsem ± 3 digri, senis bilong presa bilong het bilong mol Liklik o wankain olsem ± 0.5MPa, na dispela i mekim wok i stap gut.

Ol ikwipmen i mas kisim ful proses 'debugging' pastaim long ol i lusim faktori long meksua olsem ol i inapim ol nid bilong prodaksen bilong ol yusa.
Proses paramita debugging
Stretim spit bilong skru, tempereja, spit bilong givim kaikai na ol narapela samting bihainim ol fomula bilong yusa (olsem hai protin fomula, hai faiba fomula) long sekim sapos ol ikwipmen inap long yusim ol narapela narapela raw materiel:
Digri bilong kamap bikpela: Long rot bilong painimaut 'gelatinization degree' bilong 'starch' (we i mas bikpela moa o wankain olsem 80%);
Kapasiti stebiliti: Kapasiti i save senis oltaim long liklik o wankain olsem 5% long 3-pela 'batch'.
Konfemesen bilong ol mak bilong kisim
Ol samting bilong soim wok: Kamapim mak bilong prodaksen we ol i makim (olsem mak bilong 5 ton/aua, skelim Bikpela o wankain olsem 4.8 ton/aua), pawa konsumsen Liklik o wankain olsem 80kWh/ton (stretim bihainim fomula);
Sefti na Envairomen Proteksen: Ol das i save kamap long taim bilong wok bilong ol ikwipmen i liklik o wankain olsem 10mg/m 3 (distekta i save painim), na dispela i bihainim ol lo bilong lukautim envairomen long ples;
Givim ol pepa: Givim ol piksa bilong ol ikwipmen, ol buk bilong wok, lista bilong ol hap we i no gat strong, ol ripot bilong sekim faktori, na ol narapela samting, long meksua olsem ol yusa i ken wok na lukautim long gutpela pasin.

Bihain long ol i givim ol ikwipmen, em i gutpela long wok long stretim kwaliti bilong en long rot bilong ol bekim bihain long ol i salim:
Instolesen na debugging: Helpim ol yusa long on-sait instolesen na sekim gen sapos ol ikwipmen na prodaksen lain (olsem ol 'raw material warehouses' na ol 'cooling systems') i wok gut o nogat;
Operesen traking: Oltaim bihainim-ap visit insait long 3-pela mun, rekodim ol kain bagarap bilong ol ikwipmen (olsem skru i bagarap na sensa i bagarap), skelim ol as na mekim ol senis (olsem stretim ol skru materiel na apgredim ol sensa brend).
somarisim
Kwaliti kontrol bilong twin-skrulain bilong kamapim kaikai bilong pisi mas stat long foapela samting: "disain rasenel, komponen ekyuresi, asembli ekyuresi, na operesenel stebiliti", long pinis bilong en, mekim gut olsem ol ikwipmen i ken kamapim gut kaikai bilong pis we i inapim ol nutrisen standet na i gat gutpela fisikel samting, na tu i gat ol mak bilong sefti, durability, na isi mentenens. Dispela proses i mas bung wantaim ol samting bilong teknoloji bilong kamapim ol kaikai, skelim gut wok bilong ol ikwipmen na kos bilong prodaksen, na givim ol gutpela prodaksen garanti long ol yusa.
