Ubwino wa thovu la polyurethanemakina odzaza thovu othamanga kwambirindiye muyezo wodziwira momwe makina opangira thovu amagwirira ntchito.Mawonekedwe a thovu la makina otulutsa thovu amayenera kuweruzidwa potengera zinthu zitatu izi: kusalala kwa thovu, kufanana kwa thovu komanso kutuluka kwa thovu.Kuchuluka kwa kutuluka kwa thovu kumatanthawuza kuchuluka kwa mankhwala otulutsa thovu omwe amapangidwa chithovu chikaphulika.Chithovu chikamatuluka pang'ono ndipo thovu likakhala ndi madzi ochepa, m'pamenenso mpweya wa polyurethane umatulutsa mpweya wabwino.
Zifukwa zazikulu za kupsyinjika kwachilendo kwapolyurethane high-pressure thovu makinandi izi:
1. Ma hydraulic components a hydraulic circuit (monga ma hydraulic cylinders ndi control valves) amavala kwambiri kapena zigawo zosindikizira zimawonongeka, zomwe zimapangitsa kuti mkati mwa hydraulic circuit.
2. Pali kutuluka kwa kunja kwa kayendedwe ka mafuta a dongosolo, mwachitsanzo, chitoliro cha mafuta chathyoledwa, ndipo mawonekedwe pakati pa chitoliro cha mafuta ndi zigawo za hydraulic akuthamanga kwambiri.
3. Fyuluta yamafuta imatsekedwa ndi zosafunika mu mafuta, kutentha kwa mafuta kumakhala kokwera kwambiri, chitoliro chothira mafuta cha pampu ya hydraulic ndi yopyapyala kwambiri, ndi zina zotero, kotero kuti mafuta opangidwa ndi hydraulic pump ndi osakwanira kapena okhudzidwa.
4. Mafotokozedwe a hydraulic pump drive motor samakwaniritsa zofunikira, monga kutulutsa ndi liwiro la makina opangira thovu ndi chiwongolero chagalimoto.
