Kafukufuku wokhudza kutsegulira ndi kutseka kwapampu yamafuta
Ntchito yayikulu ya valavu yachitetezo cha pampu yamafuta ndikuchepetsa kupanikizika kwakukulu pamapopu amafuta, kuteteza ma hydraulic system kuti asachulukidwe, ndikuchita nawo chitetezo. Makhalidwe otsegulira ndi kutseka kwa valve yachitetezo ndi mgwirizano pakati pa kuthamanga kwa valve yotetezera chitetezo, kutseka kutsekeka ndi kupanikizika pamene valavu yotetezera ifika pa mlingo wothamanga. Ndikofunikira kokhazikika kwa valve yotetezera. Zimafunika kuti kupanikizika kwa dongosolo kukhalebe kosalekeza ngati n'kotheka pambuyo poti valavu yachitetezo itatsegulidwa, ndipo kutsekedwa kotsekera kuyenera kukhala kosasinthasintha momwe zingathere. Kupanikizika kotsegulira ndi kofanana, koma kwenikweni sikutheka. Tikhoza kungoyesa kuonetsetsa kuti kusiyana kwapakati pamagulu osiyanasiyana othamanga ndi ochepa momwe tingathere. Kawirikawiri amafunika kuti kutsegula kwa valve yachitetezo sikuchepera 95% ya kupanikizika kwakukulu, ndipo kutsekedwa kotsekera sikuli pansi pa 90% ya kupanikizika kwakukulu. Makhalidwe otsegulira ndi kutseka kwa valve inayake yotetezera pampu yamafuta samakwaniritsa zofunikira. Valavu yotetezera pampu yamafuta ndi valavu yachitetezo cha magawo awiri okhala ndi siteji yoyendetsa, yomwe imapangidwa makamaka ndi valavu yayikulu, valavu yoyendetsa, kasupe wamkulu wa valve ndi kuthamanga kwa valve yoyendetsa masika. Pamene kupanikizika kumbuyo kwa pampu yamafuta kumafika pa pre-pressure ya kuthamanga kwa kasupe wa valve yoyendetsa ndege, valavu yoyendetsa ndege imatsegulidwa ndipo chipinda chachikulu cha kasupe cha valve chimadutsa kupanikizika kochepa. Choncho, kusiyana kwapakati pakati pa kutsogolo ndi kumbuyo kwa valve yaikulu kumawonjezeka. Valve yaikulu imatsegula ndi kutulutsa mafuta pambuyo pa mpope mu chipinda chobwereranso dizilo, kuchepetsa kupanikizika pambuyo pa pampu ya dizilo imatsimikizira chitetezo cha dongosolo, ndiko kuti, kutsegula ndi kutseka kwa valve yaikulu kumayendetsedwa ndi valve yoyendetsa ndege. Kutsegula valavu yaikulu kukhetsa dizilo kumachepetsa kuthamanga pambuyo pa mpope ndikulepheretsa dongosolo kuti lisakule.
