The osachepera kuthamanga valavu wascrew air compressorimatchedwanso valavu yokonza kuthamanga. Zimapangidwa ndi thupi la valve, core valve, kasupe, mphete yosindikizira, screw screw, etc. Mapeto olowera a valve yochepa yothamanga nthawi zambiri amagwirizanitsidwa ndi mpweya wa silinda ya mafuta ndi gasi, ndipo mpweya wotulutsa mpweya nthawi zambiri umagwirizanitsidwa ndi kumapeto kwa chozizira.
Ntchito ya valve yochepa yothamanga
1. Valavu yochepetsetsa yocheperako imagwiritsidwa ntchito makamaka kukhazikitsa kupanikizika kwa mkati mwa unit, kulimbikitsa kufalikira kwa mafuta odzola, ndikukumana ndi mphamvu yogwira ntchito ya valve yotsitsa. Kupaka mafuta pamakina kumayendetsedwa ndi kusiyanasiyana kwa makina omwewo, popanda thandizo lina la mpope wamafuta. Makinawo akamayamba komanso osanyamula katundu, pamafunika kupanikizika kwina kuti mafuta aziyenda bwino. Valavu yochepetsetsa yochepetsetsa imatha kusunga kupanikizika mu thanki yolekanitsa mafuta kuti isagwe pansi pa 4Bar , Poyambira, perekani patsogolo pa kukhazikitsa kuthamanga kwa kayendedwe kofunikira ndi mafuta odzola kuti atsimikizire kuti makinawo ndi mafuta ndipo valavu yotsegula ikhoza kutsegulidwa.
2. Tetezani chinthu cholekanitsa mafuta. Kupanikizika kukadutsa 4bar, kumatseguka kuti muchepetse kuthamanga kwa mpweya kudutsa mu cholekanitsa mafuta ndi gasi. Kuphatikiza pakuwonetsetsa kuti mafuta ndi gasi amalekanitsa, imatha kutetezanso gawo lazosefera lamafuta ndi gasi kuti lisawonongeke chifukwa cha kusiyana kwakukulu. Amachepetsa kukhudza pachimake olekanitsa pamene makina odzaza.
3. Valavu yocheperako imakhala ngati valavu ya njira imodzi kuti mpweya wopanikizika mu dongosolo usabwererenso mu makina pamene makina atsekedwa.
Kusanthula zolakwika wamba
1. Thempweya kompresazida zimapangidwa ndi ma valve ambiri. Sing'anga ya mpweya si yabwino kapena zonyansa zakunja zimalowa mu unit. Moyendetsedwa ndi mpweya wothamanga kwambiri, tinthu tating'onoting'ono timakhudza valavu yocheperako, zomwe zimapangitsa kuwonongeka kwa magawo ochepa a valve; kapena dothi limagwidwa pakati pa malo osindikizira, zomwe zimapangitsa kulephera kwa valve yochepetsetsa yochepa.
2. Ngati sing'anga yodzazidwa ndi madzi kapena mpweya wolekanitsa wa kompresa kulephera, izo zingachititse madzi kugwedezeka kwa valavu osachepera kuthamanga, ndi valavu yochepa kuthamanga imathandizira kulephera chifukwa cha zotsatira zina, amene makamaka akuwonetseredwa ndi abnormal phokoso pamene kompresa ikuyenda.
3. Ngati mafuta ochulukirapo alowetsedwa mu kompresa ya mpweya, mafuta opaka mafuta ochulukirapo amapangitsa kuti mafuta azitha kumamatira mu valve yochepa kwambiri, zomwe zimapangitsa kuti mbale ya valve ichedwe kutseka kapena kutsegula ndi kusweka.
4. Valavu yochepetsetsa yocheperako imapangidwa molingana ndi zochitika zenizeni zogwirira ntchito. Ngati zikhalidwe zogwirira ntchito zimasinthasintha kwambiri ndikuchoka pamtengo wopangira kwa nthawi yayitali, valavu yocheperako imalephera mwachangu.
5. Pamene ampweya kompresaimayimitsidwa kwa nthawi yayitali ndikuyambiranso, chinyontho chomwe chili mumafuta opaka mafuta ndi mpweya chidzaunjikana mkati mwa chipangizocho, chomwe sichidzangowononga mbali za valavu yocheperako, komanso kuyambitsa ntchito ndi chinyezi, zomwe zingayambitse kugwedezeka kwamadzi mosavuta , mafuta omata.
6.Zinthu zosiyanasiyana monga unit resonance, ntchito yosayenera, ndi chilengedwe zidzakhudza moyo wa valve yochepetsetsa ya compressor.
