Mafuta Odziwika Zamtchire Kuchepetsa mphamvu ya njanji ya njanji yopanda kanthu 416-7101

Valavu yotsitsa imakhala makamaka yopangidwa ndi gawo lalikulu, spoul, kasupe, Chisindikizo ndi zina. Gawo lalikulu nthawi zambiri limapangidwa ndi chitsulo chachikulu kapena zitsulo za aluminium, motsutsana ndi kukana mphamvu komanso kutukwana. Spoul ndiye gawo loyambira la valavu yotsitsa, yomwe imatha kupangidwa m'mitundu yosiyanasiyana malinga ndi zosowa za dongosolo, ndipo zojambula wamba ndi mtundu wapamwamba komanso mtundu wapansi. Kasupeyo ali ndi udindo wofufuza zochitika za spoul malinga ndi kusintha kwa ma hydraulic dongosolo, pomwe chisindikizo chimawonetsetsa kukhazikika kwa valavu yotsitsa valavu.

Mfundo yogwira ntchito ya valavu yotsitsa ndikuwongolera kupsinjika kwa hydraulic dongosolo posintha mawonekedwe a phwento lalikulu. Kupanikizika kwa hydraulic dongosolo kumafika pamtengo, spoul idzakakamizika ndi zopsinjikazo, kuti zigule zazikuluzikulu ndi spool pansi zimalekanitsidwa, kuti zitheke kuti muchepetse mavuto a Hydraulic. Kupanikizika kwa hydraulic kachitidwe kakhazikika, kasupe kumakanikizapo spool pamalo oyambilirawo, kotero kuti spool yayikulu ndi supuni yolumikizirana ndi dongosolo la dongosolo.
