1. Chiwerengero chabodza
Chiwerengero cha kusokoneza aliyense amene amadziwa za compressor magwiridwe antchito. Koma kodi kugwiritsa ntchito kapangidwe kake ndi chiyani? Kodi ndi chida chosinthira, sizoncho.
Kusiyana pakati pa makina a screw ndi makina a piston ndikuti makina a piston amangocheperachepera, pomwe makina a screw agonjetse.
Zomwe zakhudzidwa ndi kapangidwe kake, makina a screw ali ndi deta yofunika, ndiye kuti, kuchuluka kwa kuchuluka kwa buku la Chingerezi, pa conkes otenthetse, VI imakhazikika. Kuchokera pakukonza ndi opaleshoni, kufunikira kwa kuchuluka kwa kuchuluka kwa kuchuluka kwa kuchuluka kwa mphamvu yakunja kwa kuchuluka kwa kukakamiza kwa kukakamiza kwa kukakamira kwamphamvu komanso kupanikizika kwambiri.
Ndiye chikuchitika ndi chiani pamene chiwerengero cha kuphatikiza ndi chachikulu kapena chaching'ono?
Ngati ikuluikulu, kapena kusiyana kumeneku ndi kwakukulu kwambiri, zimatsimikizira kuti kachitidwe kameneka kwathunthu ku kapangidwe kake kopanga. Phenomena wamkulu ndichakuti kutentha kutentha ndi kutentha kwa kuthamanga ndizokwera kwambiri, kuthamanga kwa magetsi kumakhala kochepa, ndipo kutentha kumakhala kochepa.
Ngati kuthamanga kwambiri ndi kutentha kumakhala kwakukulu kwambiri, zotsatirapo zake zimakhala makamaka mafuta odzola m'dongosolomu ndiosavuta ku Coke, sioyenera kupanga filimu yamafuta, ndipo rotor siyingakhale yopaka.
Kukakamizidwa kochepa, kutentha kwambiri kumakhudza kuzizira magalimoto, komanso kutentha kwambiri. Zotsatira zake zimakhala zofanana ndi kutentha kwambiri komanso kukakamizidwa.
Ngati ndi yaying'ono kwambiri, imakhudza kwambiri stroko (galimoto yonyowa, chisanu chosinthika). Mu zinthu zina, compressor compressor imagonjetsedwa ndi sitiroko yonyowa, kuphatikizapo ena mwa mapangidwe athu, ndipo ogulitsa amakonda kulimbikitsa monga chonchi. M'malo mwake, makina owombera amawopa kwambiri mikwingwirima yonyowa. Ngati madzi ambiri abwerera ku compression, zimayambitsa kuchepetsedwa mafuta, ndipo zotsatira zake ndizofanana ndi kutentha kwambiri.
Zachidziwikire, kuchuluka kwake ndikochepa kwambiri, ndipo kumachitikanso chifukwa cha kuvala kwa rotor ndi kulephera kutsegula ndikutsitsa.
2. Kuchita bwino kwa condenser kuli kotsika
Kugwiritsa ntchito motsutsana ndi condenser kumakhudza kutentha kwa madzi amadzimadzi komanso ngati amatha kupanga madzi. Tikudziwa kuti valavu yakukula imaperekedwa moyenera ndi madzi athunthu. Mwanjira imeneyi, kuchita bwino kwa dongosololi ndi kochulukirapo komanso kuwongolera kozizira ndiye kwakukulu. Komanso, zigawo zazikulu zimaphatikizapo kusungirako, zomwe zimagwiritsidwa ntchito pozizira mafuta. Chifukwa chake, ndikofunikira kwambiri kukhalabe ndi luso lalikulu. Kulephera kumachitika makamaka chifukwa cha kusankha kolakwika kwa njira yozizira, malo osakwanira osinthika, osakwanira ozizira ozizira, komanso kusinthana kutentha. Chifukwa chake, mfundo zazikulu monga mafani, mapampu amadzi, ndi zipsepse zimayang'aniridwa pakuyang'aniridwa.
Polankhula za izi, zotsatira zake zimakhala zabwino kwambiri. Mwachitsanzo, ngati kutentha kwa kutentha kumakhala kotsika kwambiri, zotsatira zake zimakhala zabwino kwambiri, zomwe zimapangitsa kuti zizigwira bwino ntchito zamadzimadzi. Pakadali pano, ma superheat apamwamba kwambiri ndi otsika kwambiri ndipo valavu yowonjezera imatsika, yomwe idzayambitsa kugwedeza kwa hydraulic. Kapena kusiyana pakati pa kukakamiza kwamphamvu komanso kuthamanga kwa magetsi sikokwanira, komwe kumapha makina a screw ndi makina osokoneza bongo.

Kuchita bwino kwa wopanga kumakhudza kuzizira kwa chinthucho kuti chikhazikike, pomwe sitiroko yonyowa imakhudza compressor. Ndipo chochita bwino chimayambitsa kuyamwa kwambiri kuti chikhale chokwera kwambiri, chomwe chingakhudze kutentha kwa compreskor.
Kuweruza kwa stroke yonyowa
Chiwopsezo chonyowa, pansi pa kutentha kochepa, chiweruziro sichikhala chosavuta, chimaweruzidwa ndi mzere wowiritsa wa compressor, koma bwanji za mkhalidwe wa mkhalidwe wa mpweya? Ndi mame? Makamaka kwa ozizira, ngati pali vuto pakuweruza, kumayambitsa mavuto monga kuwonongeka ndi kuperewera kwamadzi. Chifukwa chake, imatha kuweruzidwa malinga ndi chithunzi chopanikizika, kapena phindu la kutentha kwa kutentha pambuyo pa kutentha pambuyo pokonzanso. Ngati mtengo wake ndi wochepera 30k, zitha kuweruzidwa ngati stroko yonyowa.
Ndiroleni ndinene chinthu chinanso apa, valavu yokukulitsa, ndilibe mndandanda wosiyana (onani buku la Pukuda Langa la Valve). Valavu ya kukula si valavu yolamulira yonse, ndipo si onse omwe akugwira ntchito amakwaniritsa zofuna kusintha mu valavu yowonjezera. Makamaka ngolo zazikulu-zokokedwa ndi mahatchi.
4. Vuto Lalikulu la Mafuta
Kwa magetsi, zimawonetsedwa makamaka mu mtundu wa mafuta, ukhondo, kutentha kwakukulu kwamafuta mu njira yopumira mu dongosolo la scresser ndi mafuta.
Kuphatikiza apo, ilinso ndi ntchito ya kuchepetsa kwa phokoso komanso kugwedeza mabowo, koma chifukwa mafuta ena amaganiza kuti ndi osathandiza, ndiye kuti mafuta osokoneza bongo.
Mayamwidwe amadzigwetsa makamaka kuti mafuta ozungulira, ndipo izi sizodziwikiratu, kotero ntchito zapamwambazi sizingawonedwe ngati ntchito zazikulu.
Kutentha kwa mafuta kumabwera kumakhudza kwambiri ntchito yautumiki wa compressor. Nthawi zambiri, kutentha kogwira ntchito kuli pakati pa 40 ndi 60 ° C, ndipo ena opanga nawonso Marko 70 ° C. Kutentha kwambiri kwamafuta kwambiri kumayambitsa mafuta ndi kuwononga mapangidwe a filimu yamafuta. Kutentha kwamafuta kumakhudzanso kutentha kwamphamvu, komwe kumakhudza kuchuluka kwa comple. Chifukwa chake, chonde mverani kusintha kwa kusintha kwa kutentha.
Ukhondo wamafuta
Ukhondo wa mafuta ndi ukhondo wa dongosolo. Kusunga ukhondo ndiko gawo lalikulu la compressor. Compressor steresror siyofanana ndi piston compresser. Chifukwa cha zifukwa zopanga, ukhondo wa dongosolo ndiwokwera kuposa momwe piston amapikisana. Chifukwa cha kuthamanga kwambiri kwa rotor, zinthu zina zakunja zimayamwa msanga, makamaka zowononga tinthu tating'onoting'ono, zomwe zimawononga gawo lazikulu za makinawo, kapena kuwonongeka kwa malo ogulitsirawo, kapena ngakhale vuto la msonkhano wa owola. Iyenera kuwononga molunjika mota. Ngakhale tinthu tating'onoting'ono tisachite zinthu mwachindunji, zimakhudzanso mafilimu yamafuta a rotor, zomwe zimapangitsa kuti mafuta a crongor abereke, masilinda akumata, ndikuluma m'bokosi la kubereka. Choyipa kwambiri ndikuti tinthu tating'onoting'ono tipangire unyolo waufupi ndikupangitsa kuti awonongere galimoto.
Mafuta odzola mafuta a acin amakonda kununkhira fungo lopaka mafuta popenda. Kutentha kumakhala kwakukulu kwambiri pomwe chitsulo chimavalidwa kwambiri, ndipo mafuta odzola amayamba kuphika pakakhala pamwamba pa 175oc. Ngati pali madzi ambiri m'dongosolo (kupatuka kapamwamba sikoyenera, mafuta opangira mafuta ndi firiji yolimbana ndi madzi osokoneza bongo, etc.), mafuta opangira mafuta amatha kukhala acidic. Mafuta odzola mafuta a acid adzaphukira mitengo yamkuwa ndi kukumbutsani. Mbali inayi, imapangitsa kuphika kwa mkuwa; Kumbali inayo, mafuta odzola mafuta odzola omwe ali ndi ma atomu amkuwa ali ndi vuto losautsa, lomwe limapereka zofunikira kuzungulira.
Zojambula kuzungulira mayunitsi, mitundu yambiri yolakwika imayambitsidwa ndi magawo angapo. Mwachitsanzo, kulephera kwa mafuta komwe kumachitika chifukwa chosowa Mafuta kumapangitsa kuti zikhale zokakamira, rotor imakhazikika, kenako morressor moto wotsekedwa, wopondera amakumana ndi vuto. Ndipo chifukwa chiyani kusowa kwa mafuta kapena kulephera kwamafuta? M'malo mwake, zimayambitsidwa ndi kutentha kwambiri, kugwedezeka kwamadzi ndi zifukwa zina. Chifukwa chake, pokonza ogwira ntchito, izi ndi zinthu zonse zomwe zimafunikira kuyang'ana mosamala komanso kuganiza zovuta asanakonzedwe ndi kukwaniritsidwa.
1. Mafuta a mafuta nthawi yoyambira kapena opaleshoni
Vutoli limachitika chifukwa cha madzi kulowa compression, kapena pali firiji yambiri yopaka mafuta. Chonde sinthani makina osalala kuti muwone ngati firiji imachulukana.
