Odziwika bwinoPU thovu makinamakamaka amapanga zinthu za PU.Thupi lonse la makinawo limapangidwa ndi chitsulo chosapanga dzimbiri, ndipo njira yosakanikirana yosakanikirana imagwiritsidwa ntchito kuti ikhale yofanana.Ndiye, tiyenera kuchita chiyani kuti tisunge makina athu otulutsa thovu a PU?

1. Air kuthamanga dongosolo la PU thovu makina

Makina athu amayenera kuthiriridwa madzi kamodzi pa sabata kuti atsimikizire kuti mbalizo zapaka mafuta.Titha kugwiritsanso ntchito mafuta odzola kuti tizipaka mafuta pamutu wa dispenser ndi mutu woyezera.Chotsani valavu yotsegulira thanki yamafuta mwezi uliwonse kuti muyeretse ndime zolowera ndikusindikiza zigawo.Mukhozanso kupaka batala mkati kuti muteteze mafuta.

2. Dongosolo la Hydraulic la makina otulutsa thovu a PU

Zosefera siziyenera kutsukidwa pafupipafupi.Mutha kuyeretsa miyezi isanu ndi umodzi iliyonse.Muyenera kusintha fyuluta kuyeretsa kuwiri kulikonse.Sinthani mafuta a hydraulic miyezi isanu ndi umodzi iliyonse.Mukhozanso kudzoza ndi mafuta odzola kapena mafuta a hydraulic.Mukasintha mafuta atsopano chaka chilichonse, zida zamkati za tanki yamafuta ndi hydraulic reversing valve ziyenera kutsukidwa nthawi imodzi.Valavu ya hydraulic diverter imakhala ndi moyo wantchito pafupifupi zaka ziwiri.Tiyenera kukumbukira izi.

3. Yaiwisi dongosolo la PU thovu makina

Kuthamanga kwa thanki yopangira zinthu kumafuna kuti mpweya wouma ukhale nayitrogeni.Chaka chilichonse tiyenera kuchotsa fyuluta ndi kuyeretsa mkati ndi methylene kolorayidi ndi mkuwa burashi, ndiye ntchito DOP kuyeretsa fyuluta pepala otsalira methylene kolorayidi.Zisindikizo za pampu yosintha zinthu zakuda zimasinthidwa ndi kotala, ndipo zisindikizo za pampu yosinthira zinthu zoyera zimasinthidwa magawo awiri aliwonse.Ma O-mphete a mutu woyezera ndi mutu wogawira ayenera kusinthidwa miyezi isanu ndi umodzi iliyonse.

4. Kusakaniza luso la PU thovu makina

Osasokoneza thupi la nozzle pokhapokha ngati pali vuto.Mutu wamphuno umakhala ndi moyo wa majekeseni pafupifupi 500,000 ndipo ungagwiritsidwe ntchito mosalekeza ukakonza.

5. Kuwongolera kusayenda kwa makina otulutsa thovu a PU

Ngati ili mkati mwa sabata, palibe chifukwa chowongolera mopitirira muyeso.Ngati nthawi yocheperako ili yayitali, chodyeracho chimayenera kudutsa pakanthawi kochepa poyambitsa makinawo, ndipo nthawi zina pang'ono (pafupifupi masekondi 10) kuthamanga kwambiri (pafupifupi 4 mpaka 5).
