Ndi chilimwe, ndipo panthawiyi, kutentha kwambiri kwaopondera mpweyaamakhala pafupipafupi. Nkhaniyi ikufotokoza mwachidule zomwe zimayambitsa kutentha kwa kutentha kwambiri.
1. Dongosolo la compressor ya mpweya ndi lalifupi ndi mafuta.
Mlingo wamafuta ndi mbiya yamafuta imatha kufufuzidwa. Pambuyo pa kupewetsa mtima ndikukakamizidwa kuti mafuta apumulapo, malo opangira mafuta ayenera kukhala okwera pang'ono kuposa chizindikiro chapamwamba cha Mafuta (mzere wofiyira pamwambapa). Pa ntchito yamagetsi, malo opangira mafuta sangakhale otsika kuposa chizindikiro chotsika kwambiri chamafuta (mzere wofiyira pansipa). Ngati zipezeka kuti kuchuluka kwa mafuta sikukwanira kapena malo a mafuta sangathe kuonedwa, siyani makinawo nthawi yomweyo ndi mafuta.
2. Valavu yamafuta (valavu yodula mafuta) siyogwira ntchito moyenera.
Valavu yamafuta nthawi zambiri imakhala ndi malo awiri okhala ndi solenoid yomwe yatsekedwa, yomwe imatsegulidwa poyambira ndikutseka mafuta mu mutuwo pomwe makinawo amayimitsidwa. Ngati gawo silinatsegulidwe ponyamula, injini yayikulu imatentha mwachangu chifukwa chosowa mafuta, komanso zoopsa, Msonkhano wa Stolo Stred uwotchedwa.
3..
A: Ngati fyuluta yamafuta itatsekedwa ndipo valavu ya Bypass siyitsegulidwa,Cnema compresserMafuta sangathe kufikira mutu wamakina, ndipo injini yayikulu imatentha mwachangu chifukwa chosowa mafuta.
B: Fyuluta yamafuta ndi yotsekedwa ndipo mtengo woyenda umakhala wocheperako. Pali zochitika zomwe woponderezana kwa mpweya samachotsedwa kwathunthu ndi kutentha, ndipo kutentha kwa compresser kumakwera pang'onopang'ono kuti apange kutentha kwambiri. Vuto linanso ndi kutentha kwambiri kwa compressor ya mpweya pambuyo pa compressor ya mpweya kumatsitsidwa, chifukwa kuthamanga kwa mafuta amtunduwu kumatha, ndipo mafuta oponderezedwa a mpweya amatha kutsika pambuyo pake. Fyuluta yamafuta yopondera mpweya ndi yovuta, ndipo kuchuluka kwake ndikochepa kwambiri, komwe kumayambitsa kutentha kwambiri kwa compressiter.
4. Valve yowongolera yowongolera (valavu yowongolera) ikusankhidwa.
Valavu yowongolera imayikidwa patsogolo pa ozizira mafuta, ndipo ntchito yake ndikukhalabe kutentha kwa makina oyendetsa makina pamwamba pa dew.
Mfundo yake yogwira ntchito ndiyakuti chifukwa cha kutentha kochepa poyambira, dera lalikulu la mafuta limatsegulidwa, dera lalikulu limatsekedwa, ndipo mafuta odzola amaphatikizidwa mwachindunji m'makina ozizira; Matenthedwe akakhala pamwamba pa 40 ° C, valavu yowongolera mafuta imatsekedwa pang'onopang'ono, mafuta amatuluka kudzera mu wozizira ndi nthambi nthawi yomweyo; Matenthedwe akadzakula pamwamba pa 80 ° C, valavu yonse ija yatsekedwa kwathunthu, ndipo mafuta onse owuma amadutsa mu ozizira kenako amalowa mumutu kuti uzizire kwambiri mafuta ku kukula kwambiri.
Ngati valavu yowongolera imalephera, mafuta odzola amatha kulowa mu Mutu wa makina osadutsa ozizira, kuti kutentha kwa mafuta sikungatsitsidwe.
Chifukwa chachikulu chakulephera kwake ndikuti kulumikizana kwa spriction ziwiri zokhala ndi kutentha pa spool pa spool kuswa pambuyo pa kutopa, ndipo sikungathe kugwira ntchito moyenera; Chachiwiri ndichakuti thupi la Valve limavalidwa, spool imangokhala kapena kuchitapo kanthu sikunatseke bwino. Itha kukonzedwa kapena kusinthidwa kukhala koyenera.
5. Mafuta ogulitsa mafuta ndi achilendo, ndipo volida yamafuta yamafuta imatha kuwonjezeka moyenera ngati pakufunika kutero.
Voliyumu yamafuta imasinthidwa ikasinthidwa pomwe zida zimasiya fakitale, ndipo siziyenera kusinthidwa munthawi zina. Izi ziyenera kufunkhidwa kuti zipangitse mavuto.
6. Ngati mafuta amafuta amaposa nthawi yautumiki, mafuta a injini adzawonongeka.
Madzi a mafuta a injini amakhala osauka, ndipo magwiridwe osinthanitsa kutentha amachepa. Zotsatira zake, kutentha kuchokera kumutu waCnema compressersangachotsedwe kwathunthu, zomwe zimapangitsa kutentha kwa compressiter.
7. Onani ngati wozizira wamafuta amagwira ntchito bwino.
Mitundu yozizira yozizira madzi, mutha kuyang'ana kutentha kwapakati pa itlet ndi mapaipi ogulitsira. Nthawi zambiri, iyenera kukhala 5-8 ° C. Ngati ndi wotsika kuposa 5 ° C, kukula kapena block atha kuchitika, zomwe zingakhudze kutentha kusinthasintha kwa wozizira kwa wozizirayo ndikuyambitsa kutentha kotentha. Pakadali pano, kutentha kwa kutentha kumatha kuchotsedwa ndikutsukidwa.
.
Kutentha kwa madzi ozizira sikuyenera kupitirira 35 ° C, ndipo kuchuluka kwake sikuyenera kukhala kochepera 90% ya mtengo wowoneka bwino pomwe kuthamanga kwa madzi kuli pakati pa 0,3 ndi 0.5mm.
Kutentha kozungulira sikuyenera kukhala wamkulu kuposa 40 ° C. Ngati zofunikira pamwambapa sizingakwaniritsidwe pokhazikitsa nsanja zozizira, kukonza mpweya wabwino, ndikuwonjezera danga la chipinda chamakina. Mutha kuwonanso ngati fan yozizira imagwira ntchito bwino, ndipo ngati pali kulephera kulikonse, ziyenera kukonzedwa kapena kusintha.
