Isikhokelo sokuKhetha uLwalulo lomsi oluLungileyo kuMsebenzi weNkungu 

Ukukhetha ulwelo oluchanekileyo lomsi aluyonkcukacha-ngumahluko phakathi kwekrisiphu, inkungu engaguqukiyo kunye nemilomo evalekileyo, imveliso engalinganiyo, okanye nokuvalwa komatshini. Sizibonele mathupha: umatshini wenkungu ophezulu osebenza ngokugqibeleleyo kwihlobo elifumileyo laseShanghai-de abasebenzi batshintshe kulwelo olunexabiso eliphantsi, olungavavanywanga. Kwimizuzu engama-90, imveliso yehle nge-60%. Undoqo weheater wonakala. Iqela lomnyhadala liye laxinana. Eso siganeko asizange sodwa. Kule minyaka mihlanu idlulileyo, iilog zethu zenkxaso yobuchwephesha zibonisa imiba enxulumene nolwelo i-73% yongenelelo lomatshini wenkungu kwindawo ngexesha lemiboniso edibeneyo yomthombo kunye nenkungu.

Kutheni ukuKhetha uLwalulo lomsi kuchaphazela ngokuthe ngqo umatshini weNkungu

Oomatshini benkungu abapheleli nje ekutshiseni ulwelo—bawutshisa ngokushushu umxube owenziwe ngobunjineli. Umthwali wesiseko (ngokuqhelekileyo ipropylene glycol, i-triethylene glycol, okanye i-glycerin), inqanaba lokucoceka, ubungakanani beqhekeza emva kwe-atomization, kunye nokuzinza kwe-thermal kwi-280-320 ° C yonke imisela ukusebenza. Sivavanya yonke ibhetshi esiyisebenzisayo kwindlu-kungekhona i-spectrometers yelebhu yodwa, kodwa phantsi komthwalo wangempela: imijikelezo eqhubekayo yemizuzu engama-45 kwi-95% yomjikelezo womsebenzi, amaqondo okushisa aphakathi ukusuka kwi-5 ° C ukuya kwi-38 ° C, kunye nomswakama ukuya kwi-90% ye-RH.

Ulwelo olusezantsi-lucoceko lushiya intsalela eqokelela ngaphakathi kwisixhobo sokutshintsha ubushushu. Hayi emva kweeveki-emva kwemiboniso emithathu ukuya kwemihlanu epheleleyo. Eso sakhiwo sikhusela i-elementi yokufudumeza, inyanzelisa amaqondo obushushu aphezulu. Isiphumo? Ukuthotywa kobushushu bolwelo oluseleyo, ukujika kombala omdaka, ivumba le-acrid, kunye nokusilela kwangaphambi kwexesha kokutshintsha kwe-thermal cutoff. Omnye umxhasi uchaze ukutshintshwa kwebhloko yesifudumezi somatshini wenkungu kabini kwiinyanga ezisibhozo-de kube siphicothe umboneleli wabo wolwelo saza safumana i-12.7% yesiqulatho samanzi (ubuninzi beshishini yi-0.5%).

Umgangatho ophezulu we-fluid uhambisa i-viscosity eqikelelwayo kwiqondo lokushisa lokusebenza. Ubhitye kakhulu? I-overspray, ixesha elifutshane lokuxhoma, ukuxinana okungahambi kakuhle. Zityebe kakhulu? Umphunga ongaphelelanga, "umphunga" omhlophe endaweni yenkungu yokwenyani, ithontsi yombhobho. Silinganisa i-viscosity kwi-30 ° C kunye ne-60 ° C-kungekhona nje ukushisa kwegumbi-kuba oomatshini benkungu bafikelela kwi-thermal equilibrium mid-cycle.

Iikhrayitheriya eziNtathu ezingaxoxisiyo zokuSetyenziswa kobuNgcali

Ungahoyi amabango okuthengisa. Gxininisa kwezi metrics ziqinisekisiweyo:

• Ucoceko ≥99.8% - Iqinisekiswe luvavanyo lwe-GC-MS, hayi nje amaphepha eSDS. Amanzi, i-ethanol, okanye izalathiso zemethanol zinyusa isantya sokurhweba kwizinto ezininzi zentsimbi.
• Indawo edanyazayo ≥110°C - Ibalulekile kwiindawo zangaphakathi ezineemashali zomlilo. Ulwelo olungaphantsi kwe-105°C lubangele ukucaphula kuphicotho-zincwadi lwethiyetha kabini yaseBeijing kulo nyaka uphelileyo.
• Intsalela ubunzima ≤0.003g nganye 100ml emva 30-min 300 °C bhaka -Ikalwa kwilebhu yethu ekwisiza. Oku kuqikelela izinga lokwenyani ngcono kunayo nayiphi na ileyibhile “yentsalela ephantsi”.

Siyalugatya ulwelo olunedayi eyongeziweyo, iziqholo, okanye izinto ezixutywayo. Iidayi ziyancipha phantsi kwe-UV kunye nobushushu-ushiya ifilimu ephuzi kwiilensi kunye neeprojekti. Iziqhumiso zifihla i-gassing kodwa ungayiyeki. Ii-surfactants zinciphisa ukuxinezeleka komphezulu kakhulu, zibangela ukuba inkungu iwe phambi kokufikelela kwinqanaba labaphulaphuli.

Abanye banokuphikisa ulwelo lwenkungu oluqhelekileyo “olusekelwe emanzini” lukhuselekile kwaye lungabizi kakhulu. Nangona kunjalo, "isiseko samanzi" sithetha kuphela amanzi akhoyo-hayi ukuba amanzi ngowona mthombo uphambili. Ipropylene glycol / imidibaniso yamanzi ilawula imarike, kodwa umlinganiselo ubalulekile. I-70/30 PG / umxube wamanzi usebenza ngokuthembekileyo. Umxube we-40/60 ubilise ngokungafaniyo, utshica, kwaye ushiya iidiphozithi zezimbiwa ukuba amanzi epompo asetyenziswa kwimveliso.

Ukuthelekisa ulwelo kumatshini wakho-kunye nokusingqongileyo

Ayingabo bonke oomatshini benkungu abalinganayo. Iiyunithi ezindala ezine-nickel-chrome zokufudumeza iikhoyili zinyamezela izinto ezibanzi zolwelo. Iiyunithi zanamhlanje ze-ceramic-core zifuna ukunyamezela okungqongqo. Sibhala oku yonke imihla: xa sasisasaza izixhobo zeRobe BMFL Beam ecaleni kwenkungu kumboniso weZiko leMidlalo yeOlimpiki yaseShenyang, ukunqunyulwa komqadi kufuna inkungu exineneyo, ecothayo. Ulwelo olusemgangathweni lunike imizuzwana ye-12 ukubonakala. Isiko lethu le-65/35 i-triethylene glycol / propylene glycol blend yandisa imizuzwana ye-37-ngaphandle kokunyuka kokusetyenziswa kwamanzi.

Ukuphakama kutshintsha yonke into. Kwi-1,500m ngaphezu komphakamo wolwandle (eqhelekileyo kwintshona yeTshayina), iindawo zokubilisa ziyehla. Ulwelo olulungiselelwe ukusetyenziswa kwinqanaba lolwandle luba ngumphunga kwangoko kakhulu kwindlela yokutya-ebangela i-cavitation kunye ne-pressure spikes. Ngoku sigcina izinto ezimbini ezahlukeneyo: enye inikwe ireyithi ye-≤500m, enye iqinisekisiwe ukuya kuthi ga kwi-2,200m.

Ubushushu obugqithisileyo bufuna uhlengahlengiso. Ngaphantsi kwe-10°C, ulwelo oluqhelekileyo luyajiya. Imveliso yehla. Ukufudumeza kwangaphambili i-reservoir kunceda-kodwa kuphela ukuba ulwelo luhlala luzinzile. Sivavanye iimpawu ezili-17 ku -5°C. Zine kuphela ezigcinwe zihamba kwi-orifice eyi-0.3mm ngaphandle kokufudumala kwangaphambili. Zonke ezine zasebenzisa i-glycerin esters eguqulwayo-kungekhona i-glycerin ethe ngqo.

Ukukhetha ulwelo loMsi siSigqibo seNkqubo-Ayiyonto yomgca

Ukukhetha ulwelo lomsi lunxibelelana ngokuthe ngqo neshedyuli yakho yolondolozo, ukunyaniseka kwewaranti, kunye nokuthembeka kokuyilayo. Ukusebenzisa ulwelo olungelulo lwe-OEM luvala iziqinisekiso zecandelo lobushushu labanye abavelisi-kungekhona ngenxa yokunyaniseka kohlobo, kodwa ngenxa yokuba iipateni zentsalela zenza uhlalutyo lokungaphumeleli lungasebenzi. Silandelela oku: oomatshini abasebenzisa ulwelo oluqinisekisiweyo lwentsalela ephantsi kwiinyanga ezili-18 phakathi kokucocwa kombhobho. Abo basebenzisa ulwelo olungaqinisekisiweyo luyi-avareji yeenyanga ezi-4.3.

Iindleko azikho nje ixabiso le-litha nganye. Kungumsebenzi ukugungxula imigca, ixesha lokuphumla ngexesha leminyhadala, iindawo ezitshintshiweyo, kunye nomngcipheko wodumo xa inkungu isilela ukusebenza phakathi. I-$ 28 / ilitha yolwelo eyandisa ubomi be-heater ngama-300% ihlawulela ngokwayo phantsi kweziganeko ezintandathu.

I-Shenyang Fei Ya Water Art Landscape Engineering Co., Ltd. idibanise iinkqubo zenkungu kwimithombo ye-100 ukusuka kwi-2006-ukusuka kwi-Harbin Ice Festival's sub-zero plumes ukuya kwi-Dubai Fountain's synchronized mist curtains. Konke ukuthunyelwa kuqala ngokuqinisekiswa kolwelo. Wonke umxhasi ufumana i-fluid spec sheet-hayi incwadana. Kuba inkungu ayingomoya. Bubunjineli obuchanekileyo, bunqunyanyiswe emoyeni.

UkuKhethwa koMsi woMsi kuchaza into ebonwa ngabaphulaphuli bakho-kunye nento egcinwa liqela lakho. Khetha ulwelo oluziphatha ngendlela efanayo ezinzulwini zobusuku njengoko lwenza emini emaqanda, emvuleni okanye kubushushu obomileyo, bonisa emva komboniso. Asiyombono nje leyo. Leyo yinkqubo yokusebenza.
