Chithunzi cha ND447600-1820EVAPORATOR
Mfundo zazikuluzikulu ndi ntchito zazikulu za bulldozer evaporatorBulldozer evaporator ndi chipangizo chosinthira kutentha chomwe chimagwiritsidwa ntchito m'makina omanga monga ma bulldozer, omwe makamaka amakwaniritsa kutengera kutentha kudzera pakusintha kwagawo. Cholinga chake chachikulu ndikutenthetsa pang'ono-kupanikizika ndi kutsika{2}}kwamadzimadzi a mufiriji mpaka kuwira, ndi kutenthetsa kwambiri poyamwa kutentha kwa zinthu zozungulira (monga zoziziritsira injini kapena mafuta a hydraulic), potero kukwaniritsa zolinga zoziziritsira kutentha. Chidacho nthawi zambiri chimakhala ndi magawo awiri: chipinda chotenthetsera (chopereka gwero la kutentha) ndi chipinda cha evaporation (kumaliza kusintha kwa gawo ndi kusinthana kwa kutentha), ndi kukana kutentha kwambiri, kuthamanga kwambiri, komanso kusinthasintha kwa zinthu zopanda ntchito. Ndi gawo lofunikira la bulldozer hydraulic system ndi kuzirala. Bulldozer evaporator ndi chimodzi mwazinthu zofunika kwambiri mu bulldozer air conditioning system, zomwe zimagwiritsidwa ntchito kwambiri kuti zikwaniritse ntchito ya firiji kudzera munjira yosinthira kutentha. Mfundo yake yogwirira ntchito imachokera pa kusintha kwa magawo a firiji: kutsika-kutentha ndi kutsika{8}}zozizira zamadzimadzi zothamanga zimalowa mu evaporator ndikusintha kutentha ndi mpweya wotentha womwe ukuyenda kudzera mu evaporator mu kanyumba. The refrigerant imatenga kutentha ndipo imasanduka nthunzi kukhala mpweya, pamene kuchepetsa kutentha kwa mpweya wozungulira ndi kupereka mpweya ozizira kwa cockpit. evaporator ndikuletsa kuzizira). Chifukwa cha malo amene ma bulldoza amagwirira ntchito amakhala afumbi komanso amanjenjemera, ma evaporator ake amayenera kusamva kugwedezeka komanso kugwedezeka, ndipo nthawi zambiri amakhala ndi fumbi{12}}maukonde otsimikizira kuti zonyansa zingalowe.
Ntchito yayikulu ya bulldozer evaporator
Monga chigawo chachikulu cha bulldozer air conditioning system, evaporator imapereka mwachindunji magwiridwe antchito a zida ndi chitonthozo cha ogwiritsa ntchito, zomwe zikuwonetsedwa pazinthu izi:
Onetsetsani kuti malo a cockpit ali omasuka
Ma bulldozers akamagwira ntchito-kumalo otentha kwambiri (monga malo omangira panja m'chilimwe), kutentha mkati mwa kabati kumakonda kukwera kwambiri. Evaporator imachepetsa kutentha mpaka pamlingo woyenera (nthawi zambiri 20-26 digiri) kudzera mufiriji, kupeŵa ogwira ntchito ku kutentha kwa kutentha kapena kutopa chifukwa cha kutentha kwakukulu, ndikuwongolera chitetezo ndi kukhazikika kwa ntchito.
Kukhazikika kuti agwirizane ndi zovuta zogwirira ntchito
Mabulldozer nthawi zambiri amayendetsa m'misewu yamatope, yafumbi, ndi mabwinja. Mapangidwe osindikizira ndi anti vibration mawonekedwe a evaporator amatha kuteteza fumbi kuti lisalowe ndikuyambitsa kutsekeka, ndikuwonetsetsa kusinthana kwa kutentha kosasunthika pansi pa kugwedezeka kwakukulu ndikusunga magwiridwe antchito abwinobwino a makina owongolera mpweya.
Gwirizanani ndi{0}}ntchito yopulumutsa mphamvu ya makina oziziritsira mpweya
Evaporator, kompresa, condenser ndi zigawo zina zimagwirira ntchito limodzi kuti zichepetse kugwiritsa ntchito mphamvu zamagetsi m'nyengo ya refrigerant pogwiritsa ntchito kusinthana kwa kutentha. Mwachitsanzo, kutentha kwa pamwamba pa evaporator kumakhala kotsika kwambiri, sensa ya kutentha imayambitsa kompresa kutseka, kupewa chisanu ndi kusokoneza kutentha kwa kutentha, potero kuchepetsa mphamvu zonse zamakina.
Wonjezerani moyo wautumiki wa zida
Malo oyendetsa bwino amatha kuchepetsa zolakwika za ogwiritsa ntchito chifukwa cha kukhazikika komanso kutsika pang'ono kwa zida zolephera; Panthawi imodzimodziyo, mapangidwe olimba a evaporator (monga anti-zophimba corrosion) angagwirizane ndi nyengo yovuta ya malo omangapo, kuchepetsa kufupikitsa kukonzanso ndi kusintha, ndi kukulitsa moyo wonse wa zipangizo.

Ngakhale evaporator ya bulldozer ndi gawo la makina owongolera mpweya, kutentha kwake koyenera komanso kukana madera ovuta kumakhudza mwachindunji magwiridwe antchito, chitonthozo cha opareshoni, komanso ndalama zogwiritsira ntchito zida. Pazida zamakina omanga, kukhathamiritsa magwiridwe antchito a evaporator ndi gawo lofunikira pakuwongolera mapangidwe amunthu komanso kudalirika kwa makinawo. Malo ogwiritsira ntchito
Kuwonongeka kwa kutentha kwa hydraulic system: Pakugwira ntchito kwa bulldozer, kutentha kwamafuta a hydraulic kumakwera, ndipo evaporator imatenga kutentha kudzera mu vaporization ya firiji kuti isunge kutentha kwa hydraulic system ndikupewa kuchepa kwachangu kapena kuwonongeka kwa zigawo zomwe zimayambitsidwa ndi kutenthedwa.
Kuzizira kwa injini: imagwira ntchito limodzi ndi rediyeta kuti ipititse patsogolo kutentha kwapakati posintha magawo, makamaka oyenera kugwira ntchito mosalekeza-malo otentha kwambiri (monga migodi ndi malo omanga).
Special ntchito chikhalidwe kutambasuka: Ngati bulldozers nawo lifiyamu munali madzi oipa ndi zinyalala ntchito zotsalira mankhwala (monga electrolytic zotayidwa slag lifiyamu m'zigawo ntchito wothandiza), iwo akhoza kaphatikizidwe evaporators MVR kukwaniritsa madzi kuchira ndi kuchepetsa umuna chilengedwe, kuchepetsa kuwononga mphamvu ndi 50% poyerekeza ndi zida zachikhalidwe.
Ubwino waukadaulo
Kuchita bwino komanso kupulumutsa mphamvu-kupulumutsa mphamvu: Mukamagwiritsa ntchito ukadaulo wa MVR, kuthamanga kwa nthunzi yachiwiri kumachepetsa mphamvu yamagetsi, yomwe ili yoyenera "kugwiritsa ntchito mphamvu pang'ono, kupirira kwambiri" kwa ma buldoza.
Kusinthasintha kwamphamvu: Ikhoza kusinthika kuzinthu zosiyanasiyana (monga mafuta a hydraulic ndi ozizira) mwa kusintha mphamvu yogwiritsira ntchito (kuthamanga kwachibadwa / kuchepetsa) kuti ikwaniritse ntchito zosiyanasiyana za bulldozers.
Kuphatikizika kwa makina: Ma evaporator amakono ali ndi machitidwe owongolera kutentha (monga ukadaulo womwewo monga makina opangira opaleshoni), omwe amatha kusintha kuchuluka kwa mpweya munthawi yeniyeni ndikusinthira kusinthasintha kwa kutentha panthawi yamphamvu ya bulldozer.
