Meshing clearance chu 0.1-0.3mm ah dah tur a ni. Clearance a lian lutuk chuan gear shaft position siamrem emaw gear thlak emaw a ngai a ni.
Nga chaw siamna machine-a heating leh cooling system tihchangtlun
1. Cooling system tihchak
• Tui kal dan tur ruahmanna:
o Tui lumna chu 32℃aia tlem emaw a tlukpui emaw a nih a ngai . Thlasik lai chuan cooling tower tui supply flow tihpun theih a ni (recommended Design flow 120% aia tam emaw, a tlukpui emaw), cooling tower filler leh pipe scale te chu tihfai fo tur a ni (kar 2 danah vawi khat 5% citric acid solution hmanga tihfai) heat exchange efficiency tihhniam loh nan.
o Barrel cooling jacket hi scaling vangin heat dissipation tha lo tak a ni. High-pressure water gun (pressure<=10MPa) hmangin jacket channel chu flush theih a ni a, chu chuan outlet water temperature danglamna chu 5℃aia Greater emaw a tlukpui emaw a nih theih nan (inlet water chu 30℃a nih chuan outlet water chu<=35℃a ni tur a ni).
• Mold cooling: Nga chaw pekna mold hole diameter hi 1-5mm a ni tlangpui. Thlasik lai chuan mold cooling water pressure chu 0.3-0.5MPa ah dah tur a ni a, water flow rate chu 1.5m/s aia tam emaw, a tlukpui emaw a ni tur a ni a, hei hian mold hole chhunga temperature sang takah material chu a gelatinize loh nan. Kar tin mold hole chhunga thil awm chhunte chu compressed air (pressure 0.6MPa) hmangin thlawh chhuah tir thin ang che.
2. Heating system siamthat dan tur
• Temperature control calibration: Thlasik lai chuan ambient temperature a san chuan barrel heating section set temperature chu 5-10℃in tihhniam theih a ni (original setting chu 120℃a nih chuan 110-115℃ah siamrem theih a ni) a, chu chuan material a lum lutuk leh denaturation a awm loh nan. Chutih rual chuan thermocouple thermometer hmangin section tin temperature tak tak leh instrument display (±3℃phal a ni) inkar deviation chu calibrate rawh. A aia tam a nih chuan heating rod emaw temperature controller emaw thlak a ngai a ni.

Sangha chaw siamna line atana electrical leh control system venhimna
1. Moisture-proof leh heat-dissipating electrical cabinet te tansangha chaw siamna line
• Environmental control: Electrical cabinet-ah temperature-controlled dehumidifier dah tur a ni (humidity setting 60% RH aia tlem emaw, a tlukpui emaw). Thlasik laiin nitin machine i start hmain cabinet chhungah tui condensed a awm leh awm loh enfiah hmasa phawt ang che. Moisture-proof silica gel desiccant dah theih a ni (a rawng a danglam chuan a hun takah thlak leh theih a ni). Cabinet kawngka cooling fan hi darkar 24 chhung a kal a ngai a, fan filter chu ni 3 danah leivut a awm loh nan silfai tur a ni (accumulation thickness<=1mm).
• Line inspection: Motor terminal leh contactor contact te chu temperature sang vangin carbonized a nih leh nih loh enfiah (black color thlak a ngai) tih hi ngaihtuah ber tur a ni. Cable insulation layer a chhe emaw, a nem emaw a nih chuan short circuit a chhiat loh nan a khuh emaw thlak nghal emaw a ngai a ni.
2. Motor leh sensor venhimna
• Motor heat dissipation: The housing temperature of the main motor should be ≤75℃. In summer, an axial flow fan (air volume ≥300m³/h) can be installed at the tail of the motor. Use compressed air to blow away the dust on the motor heat sink every two weeks (must be cleaned when the accumulation thickness is >2mm a ni).
• Sensor calibration: Pressure sensor leh temperature sensor te hi temperature sang takah chuan an drift duh hle. Thla tin standard instrument (eg pressure sensor error<=1% FS) hmangin calibrate tur a ni a, hei hian signal deviation avanga feed quantity dik lo leh temperature control dik lo a awm loh nan.
A chunga kan sawi takte hi twin-screw fish feed production line-a mechanical transmission system enkawlna atana summer maintenance fimkhurna leh hmanraw hrang hrang te, heating leh cooling systems optimization te, electrical leh control system venhimna te a ni.
