Long atikol i go pinis, mipela i bin kamapim ol 'summer mentenence precautions' na ol rot bilong lukautim 'mechanical transmission system' bilong 'twin-screw'lain bilong kamapim kaikai bilong pis, wok bilong stretim gut ol samting bilong hatim na kol, na lukautim ol samting bilong pawa na kontrol. Dispela atikol i kamapim ol spesel mentenens, sefti na imejensi menesmen, na mentenens plen na rekot bilong ol 'raw materials' na 'molds' bilong lain bilong kamapim kaikai bilong pis.
Spesel mentenens bilong ol 'raw materials' na 'molds' bilong ol masin bilong wokim kaikai bilong pis
1. Moisture-pruf menesmen bilong ol raw materiel
• Ples bilong putim: Ol samting bilong kaikai bilong pis (olsem kaikai bilong pis na kaikai bilong soyabin) i mas stap long ol sel we i stap 30cm long graun na 50cm long wol. Haus bilong putim ol samting i mas gat wanpela 'dehumidifier' (humidity ≤55% RH), na 'ventilator' i mas gat 10-pela taim long wanpela aua long stopim ol samting long pulim wara na bung wantaim na pasim 'feeder'.
• Sekim pastaim long tritim: Sais bilong ol liklik hap bilong ol 'raw materials' we ol i brukim i mas wankain (≥90% long 80-mesh sieve). Long taim bilong san, sekim sapos i gat ol samting i pas long 'feeding hopper' pastaim long yu kirapim masin long olgeta de. Ol i ken putim wanpela 'vibrator' (amplitude 2-3mm) insait long 'hopper' bilong stopim 'bridging'.
2. Gutpela wok bilong klinim ol 'mold'
• Klinim long intanet: Bihain long wokim, yusim 'corn starch' (wara i stap insait long en ≤12%) long klinim skru na 'mold' inap 10-pela minit long wanpela emti ron bilong stopim ol samting i stap yet long 'ferment' na bagarapim ain.
• Offline mentenens: Sokim mol insait long 5% sodium hydroxide solusen inap 2-pela aua long olgeta wik, klinim gris i stap yet insait long hul bilong mol wantaim wanpela kopa bras, bihain wasim wantaim klinpela wara na draim (temperature 80 digri, taim 30 minit) long stopim hul bilong mol long rus na kamapim i no stret seip.
Sefti na imejensi menesmen bilong masin bilong wokim kaikai bilong pis
1. Sefti proteksen bilong ol ikwipmen
• Tes bilong lukautim 'overload': Mekim olsem 'motor overload' long olgeta mun (olsem mekim 'feed amount' i go antap), testim sapos 'thermal relay' i wok insait long 10-pela seken long 1.2 taims bilong 'rated current', na 'over-temperature alarm' (set veliu 80 digri) i mas kisim tes wantaim wanpela 'heating response plate' long luksave long 'sensitivity' bilong en long olgeta wik.
• Ol samting bilong stopim paia: Ol i mas putim ol drai paura paia ekstingusa klostu long prodaksen lain (i no ken liklik long 1 long 50 mita), ol i mas putim ol smok sensa insait long lektrikel kebinet, das bilong ol samting bilong wokim samting i isi long bungim long taim bilong san, na ol das i stap klostu long ol ikwipmen i mas klinim wantaim wanpela 'vacuum cleaner' long olgeta de (mumulation thickness ⤉ 0.5mm).
2. Wokim plen bilong imejensi
• Koling sistem i no wok gut: Sapos wara bilong kol i no wok gut, orait kwiktaim pasim na kirapim 'spare water tank' (kapasiti ≥ 30 minit bilong yusim), opim olgeta hul bilong 'heat dissipation' bilong baret long wankain taim, na yusim ol 'axial flow fan' long fosim kol bilong abrusim skru long lok bikos long bikpela hat.
• Tritmen bilong 'motor overheating': Taim 'motor temperature' i winim 80 digri, em i gutpela long pasim na sekim 'bearing clearance' (allowable ≤ 0.1mm) na 'winding insulation resistance' (≥ 0.5MΩ). Sapos 'insulation' i pundaun, ol i ken kukim long wanpela 'drying oven' (tempereja 105 digri) inap 48 aua long mekim 'insulation' i wok gut gen.

| Skru na barel inspeksen | Wanpela taim long wik | Skelim bagarap, klinim ol samting bilong wokim 'coking', na putim 'anti-'rust oil (em i gat bikpela hat) long pes bilong skru |
| Senisim oil bilong gia | Olgeta 2-pela mun | Taim yu senisim, klinim insait wol bilong giaboks wantaim kerosin, na sekim 'viscosity' bilong oil pastaim long putim nupela oil (≥180cSt long 40 digri) |
| Klinim wara bilong kol | Olgeta 2-pela wik | Yusim 'descaling agent' long klinim inap 30 minit, bihain wasim wantaim klinpela wara, na meksua olsem wara i ron ≥2m/s |
| Dehumidifikesen bilong lektrik kebinet | Olgeta de | Senisim 'desiccant', sekim wok bilong 'fan', na 'cabinet temperature' i stap ≤40 digri |
| Ventileisen bilong haus kago bilong ol samting | Operesen i go het yet | Mekim gut olsem humiditi insait long haus kago em i ≤50% RH, na mak bilong putim ol samting bilong wokim samting i go antap em i ≤2 mita long abrusim ol samting i stap aninit long presa na bung wantaim |
As bilonglain bilong kamapim kaikai bilong piswok bilong lukautim long taim bilong san em "kontrolim tempereja, stopim wara, na stopim wear". Long rot bilong strongim wok bilong 'cooling system', lukautim gut 'electrical system', na sotim taim bilong sekim ol bikpela samting, dispela i ken daunim tru 'equipment failure rate'. Long wankain taim, ol i mas stretim 'maintenance frequency' bihainim 'production load' (olsem sotpela taim long sekim ol bikpela hap bilong en long olgeta de long taim bilong 'high-load' prodaksen) long mekim gutpela wok bilong 'twin-screw fish feed production line insait long wanpela 'high-temperature' envairomen na long mekim 'fis feed' prodaksen i kamap gutpela na i gat kapasiti.
