Momwe mungachitire kukonza nthawi zonsemavavuMa valve odziyimira okha ndi opangidwa ndi mpweya, hydraulic ndi magetsi. Kuyang'anira kukonza nthawi zonse ndikuwona ngati mphamvu zawo ndi zochepa kwambiri kapena zapamwamba kwambiri, zomwe zingakhudze momwe valavu imagwirira ntchito. Chachiwiri ndikuwona zowonjezera zowonjezera kuti zisawonongeke kapena kutsekeka. Palinso kuwona ngati mapaipi amagetsi atuluka kapena asweka, komanso ngati mawonekedwe ake ndi otayirira.
Pali mpweya woipa womwe umabwera chifukwa cha kuthamanga kwa fyulutama valve ochepetsera, ma valve a solenoid, ma positioner ndi zina zowonjezera. Kenako pali ntchito ya actuator ya valavu, kaya silinda ya valavu ikutuluka kapena yatsekeka, ndipo tsinde la valavu lazimitsidwa. Kaya mpando wa valavu wadzimbirika komanso ngati pali kutuluka kwa mkati kapena kutuluka kwakunja. Ma valve osadzipangira okha amagwira ntchito pamanja, koma palibe kulephera kwa mphamvu ndi zida zothandizira, kulephera kwina kumafanana kwenikweni.
Mfundo zina zofunika kuziganizira pakugwiritsa ntchito tsiku ndi tsiku:
1. Ma valve amagawidwa m'magulu awiri:mavavu a dziko lapansi,mavavu a mpira, ma valve a chipata, ma valve a gulugufe,valavu yolumikiziras, ndi zina zotero. Valve ikayikidwa ndikugwiritsidwa ntchito, mafuta kapena molybdenum disulfide ayenera kuyikidwa pa ulusi wa tsinde la valve ndi mabolts, zomwe zingapereke mafuta abwino. Nthawi yomweyo, imathanso kusiyanitsa malo okhala ndi asidi ndikugwira ntchito ngati gawo loteteza.
2. Sungani valavu yoyera, makamaka pa mavalavu akunja. Ngati kuli kofunikira, onjezani zophimba zoteteza mavalavu ndi ma flange.
3. Musagwiritse ntchito mphamvu yoopsa potsegula ndi kutseka valavu, ngakhale mutagwiritsa ntchito chotenthetsera cha afterburner, simungagwiritse ntchito mphamvu yochulukirapo. Mwachitsanzo, kugwiritsa ntchito mphamvu yochulukirapo kungathe kuwononga mosavuta gasket yotsekera pamutu wa valavu ya valavu yoyimitsa.
4. Kufananiza kwa valavu kuyenera kufanana, mwachitsanzo, gudumu lamanja ndi valavu ziyenera kufanana, apo ayi gawo lapamwamba la tsinde la valavu lidzakhala lozungulira komanso loterera mosavuta.
5. Musaike zinthu zolemera kapena kuponda pa valavu.
6. Pali kutuluka kwa madzi m'thupi la valavu, komwe kuyenera kuchitidwa malinga ndi malo otayikira madzi. Mwachitsanzo, ngati malo opakira valavu yotseka akutuluka madzi, boluti ya gland yopakira ikhoza kusinthidwa moyenera, ndipo mbali ziwirizo zitha kulinganizidwa.
Kusamalira tsiku ndi tsiku, ngati pali vuto m'gawo limenelo, mutha kupereka mankhwala oyenera popanda kuwononga kwambiri. Nthawi zina pamafunika kusintha ziwalo kapena kutseka kapena kuyikanso mafuta, ndi zina zotero, nthawi zambiri kuyeretsa ndikudzaza mafuta panthawi yake, zomwe zingapangitse kuti ntchito yake ikhale yayitali komanso kupewa dzuwa ndi mvula.
