Mfundo yogwira ntchito ya valve yotetezera
Chigawo chilichonse chamafuta a hydraulic pachofufutira chimakhala ndi valavu yachitetezo, ndipo chilichonse chimagwirizana ndi valavu yotetezera. Valavu yotetezera ndi mtundu wa valve yothandizira, yomwe imapangidwa ndi kasupe, mpando wa masika, singano ya valve ndi kulowetsa mafuta pansi.
Mafuta othamanga kwambiri akalowa mu chipangizo chogwirira ntchito, kupanikizika kumawonjezeka pang'onopang'ono kupyolera muzitsulo zapansi za mafuta, ndipo pang'onopang'ono kugonjetsa mphamvu yopondereza ya masika. Pamene valavu yotetezera ifika pazitsulo zokhazikika, kasupe amatsegulidwa kwathunthu, ndipo mafuta a hydraulic amalowa m'mafuta kumbuyo kudzera mu singano ya valve, ndikupereka masewera athunthu ku ntchito ya chipangizo chotetezera.
Ntchito ya valve chitetezo
Chifukwa chomwe valavu yachitetezo imayikidwa mu gawo lamafuta logwira ntchito pachochita chilichonse cha valavu yayikulu ndikuchepetsa kupanikizika kwakukulu kwa dera lamafuta. Mwachitsanzo, kupanikizika kwa valve yaikulu yothandizira kumasinthidwa pamanja. Pamene kupanikizika kwa mpumulo kupitirira kupanikizika kwa valve yotetezera, valavu yothandizira imatsegula kuti ichepetse kupanikizika, kotero kuti dera la mafuta logwira ntchito silidutsa kupanikizika kwa valve yotetezera, ndipo dera la mafuta ndi lotetezeka komanso losalala. . Ntchito ina ndi yakuti panthawi yomanga chofukula, ngati pali chinthu cholemera chomwe chikugwa kuchokera kutalika ndikugunda silinda, ndowa, boom, ndi zina zotero, ngati palibe valavu yotetezera kuteteza dera la mafuta a hydraulic, hydraulic yaikulu. kukhudzidwa kumapangitsa kuti chubu liphulike, kuwononga spool ndi chisindikizo cha valavu yowongolera, komanso kuwononga pampu yayikulu, chifukwa chake ntchito yoteteza chitetezo ndiyofunikira kwambiri.
