Ndipo zikuwonetsedwa mu mgwirizano. Chitoliro chachitsulo chikhoza kuperekedwanso molingana ndi kulemera kwa chiphunzitso.

    Kulekerera kulemera:
    Malinga ndi zofunikira za wogula, pambuyo pokambirana pakati pa wogulitsa ndi wogula, ndi mu mgwirizano, kupatuka pakati pa kulemera kwake ndi kulemera kwake kwa chitoliro chachitsulo kudzakwaniritsa zofunikira izi:
    a) Chitoliro chachitsulo chimodzi: ± 10%;
    b) Gulu lililonse la mapaipi achitsulo okhala ndi kukula kochepa kwa 10 t: ± 7.5%.

    Chofunikira Choyesa

    Mayeso a Hydraustatic:

    Chitoliro chachitsulo chiyenera kuyesedwa hydraulically mmodzimmodzi. Kuthamanga kwakukulu koyesa ndi 20 MPa. Pansi pa kukakamizidwa kwa mayeso, nthawi yokhazikika iyenera kukhala yosachepera 10 s, ndipo chitoliro chachitsulo sichiyenera kutuluka.

    Wogwiritsa ntchito akavomera, kuyesa kwa hydraulic kumatha kusinthidwa ndi kuyesa kwa eddy panopa kapena kuyesa kwa maginito kutayikira.

    Mayeso Osawononga:

    Mipope yomwe imafuna kuyang'anitsitsa kwambiri iyenera kuyang'aniridwa ndi ultrasonically mmodzimmodzi. Pambuyo pa zokambiranazo zimafuna chilolezo cha chipanicho ndipo zafotokozedwa mu mgwirizano, mayesero ena osawononga akhoza kuwonjezeredwa.
