Thuziak hmasa lamah khan twin-screw-a mechanical transmission system enkawlna atana summer maintenance fimkhur dan leh hman dan tur kan rawn tarlang tawh asangha chaw siamna line, heating leh cooling system tihchangtlunna te, electrical leh control system te venhimna te a ni. He thuziak hian sangha chaw siamna line-a raw material leh mold-te enkawlna bik, himna leh emergency management, leh enkawlna ruahmanna leh record-te a tarlang a ni.
Sangha chaw siamna hmanrua atana raw material leh mold te a bik taka enkawl
1. Raw materials te chu moisture-proof hmanga enkawl dan
• A dahna hmun: Sangha chaw raw materials (fish meal leh soybean meal ang chi) te chu lei atanga 30cm leh bang atanga 50cm a hla shelf-ah dah a ngai a ni. Warehouse-ah hian dehumidifier (humidity ≤55% RH) dah tur a ni a, ventilator-ah darkar khatah vawi 10 ventilated tur a ni a, chutiang chuan raw materials-in moisture a hip loh nan leh agglomerating a awm loh nan feeder block tur a ni.
• Pretreatment inspection: Raw materials chi hrang hranga particle size chu a inang vek tur a ni (≥90% through an 80-mesh sieve). Thlasik lai chuan nitin machine i start hmain feeding hopper-ah agglomerated material a awm leh awm loh enfiah hmasa phawt ang che. Bridging awm loh nan hopper chhungah hian vibrator (amplitude 2-3mm) dah theih a ni.
2. Mold tihfai \\ha
• Online cleaning: A siam zawh hnuah corn starch (tui awm zat ≤12%) hmangin screw leh mold chu minute 10 chhung empty run-ah silfai la, residual material chu a fermenting loh nan leh metal a corroding loh nan.
• Offline maintenance: Kar tin darkar 2 chhung 5% sodium hydroxide solution-ah mold chu hnim la, mold hole chhunga grease awmsa chu copper brush hmangin silfai la, chutah chuan tui thianghlim hmangin silfai la, vawt rawh (temperature 80℃, time 30 minutes) mold hole chu a rust loh nan leh feed shape mumal lo a siam loh nan.
Sangha chaw siamna machine himna leh emergency enkawl dan tur
1. Thil hmanrua himna tur venhimna
• Overload protection test: Thla tin motor overload simulate (feed amount artificial taka tihpun ang chi), thermal relay chu second 10 chhungin rated current aiin a let 1.2-in a thawk em tih test la, over-temperature alarm (set value 80℃) chu kar tin response sensitivity atan heating plate hmanga test a ngai a ni.
• Kangmei laka inven dan: Production line bulah dry powder fire extinguisher dah tur a ni (meter 50-ah 1 aia tlem lo), electrical cabinet-ah smoke sensor dah tur a ni a, raw material dust hi thlasik laiin a awm khawm awlsam a, hmanrua chhehvela leivut awmte chu nitin vacuum cleaner hmanga tihfai tur a ni (accumulation thickness ≤ 0.5mm).
2. Emergency ruahmanna siam
• Cooling system a chhiat: Cooling water a inthlak chuan spare water tank chu khar nghal la, activate nghal rawh (capacity ≥ 30 minutes of use), barrel chhunga heat dissipation hole zawng zawng chu a rualin hawng vek la, axial flow fan hmangin force cooling hmangin screw chu temperature sang vanga a lock loh nan force rawh.
• Motor lum lutuk enkawlna: Motor temperature 80℃a pelh chuan shut down a ngai a, bearing clearance (allowable ≤ 0.1mm) leh winding insulation resistance (≥ 0.5MΩ) te enfiah a ngai bawk. Insulation a tlak chuan drying oven (temperature 105℃)-ah darkar 48 chhung baked theih a ni a, chu chuan insulation performance a siam tha leh thei a ni.
