Umhlahlandlela Wokukhetha Uketshezi Lwentuthu Ukuze Usebenze Kakhulu Komshini Wenkungu 

Ukukhetha uketshezi lwentuthu olufanele akuyona imininingwane—kungumehluko phakathi kwenkungu ecwebile, inkungu engashintshi kanye nemibhobho evalekile, ukuphuma okungalingani, noma ukuvala umshini. Sizibonele mathupha: umshini wenkungu osezingeni eliphezulu osebenza kahle ehlobo elinomswakama wase-Shanghai—kuze kube yilapho izisebenzi zishintshana ngoketshezi olubiza kancane, olungahloliwe. Phakathi nemizuzu engu-90, okukhiphayo kwehle ngo-60%. I-heater core yonakalisiwe. Ithimba lomcimbi likhungathekile. Leso sigameko asizange sibe sodwa. Kule minyaka emihlanu edlule, amalogi ethu osekelo lobuchwepheshe abonisa izinkinga ezihlobene noketshezi zenza u-73% wokungenelela komshini wenkungu osendaweni phakathi nemibukiso edidiyelwe yomthombo nenkungu.

Kungani Ukukhetha Uketshezi Lwentuthu Kuthinta Ngokuqondile Umshini Wenkungu Uptime

Imishini yenkungu ayigcini nje ngokushisisa uketshezi—ihwashisa ingxube eklanywe ngokunembile. I-base carrier (ngokuvamile i-propylene glycol, i-triethylene glycol, noma i-glycerin), izinga lokuhlanzeka, usayizi wezinhlayiyana ngemva kwe-atomization, kanye nokuzinza kokushisa ku-280-320 ° C konke kunquma ukusebenza. Sivivinya iqoqo ngalinye esilisebenzisa endlini—hhayi ngama-spectrometer zelebhu kuphela, kodwa ngaphansi komthwalo wangempela: imijikelezo eqhubekayo yemizuzu engu-45 kumjikelezo wemisebenzi engu-95%, amazinga okushisa e-ambient asuka ku-5°C kuya ku-38°C, kanye nomswakama ofika ku-90% RH.

Uketshezi oluhlanzekile kancane lushiya izinsalela ezinqwabelana ngaphakathi kwesishintshi sokushisa. Hhayi ngemva kwamasonto—ngemva kwemibukiso emithathu kuya kwemihlanu egcwele. Leso sakhiwo sivikela i-elementi yokushisisa, okuphoqa izinga lokushisa eliphezulu. Umphumela? Ukuwohloka okushisayo koketshezi olusele, ukushintsha kombala onsundu, iphunga le-acrid, nokwehluleka ngaphambi kwesikhathi kweswishi yokusika okushisayo. Iklayenti elilodwa libike ukuthi lishintsha ibhulokhi yalo yomshini wenkungu kabili ezinyangeni eziyisishiyagalombili—kwaze kwaba yilapho sihlola umhlinzeki walo owuketshezi futhi sathola u-12.7% wokuqukethwe kwamanzi (ubukhulu bemboni bungu-0.5%).

Uketshezi olusezingeni eliphezulu luletha i-viscosity ebikezelwayo ekushiseni okusebenzayo. Mncane kakhulu? I-overspray, isikhathi esincane sokulenga, ukuminyana okungekuhle. Kujiye kakhulu? Ukuhwamuka okungaphelele, “umusi” omhlophe esikhundleni senkungu yangempela, ukuvuza komlomo. Sikala i-viscosity ku-30°C no-60°C—hhayi nje izinga lokushisa legumbi—ngoba imishini yenkungu ifinyelela ukulingana okushisayo phakathi nomjikelezo.

Imibandela Emithathu Engaxoxiswana Yokusetshenziswa Kochwepheshe

Ziba izimangalo zokumaketha. Gxila kulawa mamethrikhi aqinisekisiwe:

• Ubumsulwa ≥99.8% - Kuqinisekiswe ukuhlolwa kwe-GC-MS, hhayi nje amashidi e-SDS. Amanzi, i-ethanol, noma i-methanol ilandelela ukugqwala kusheshisa ukugqwala ezindaweni eziningi zensimbi engagqwali.
• Iphoyinti le-Flash ≥110°C - Ibalulekile ezindaweni zasendlini ezinamashashamlilo. Uketshezi olungaphansi kuka-105°C ludale izingcaphuno ekucwaningweni kwetiyetha okubili kwaseBeijing ngonyaka odlule.
• Isisindo sensalela ≤0.003g nge-100ml ngayinye ngemuva kokubhaka okungu-30-min 300°C - Kukalwe elebhu yethu esizeni. Lokhu kubikezela izinga lokungasebenzi kahle langempela kunanoma iyiphi ilebula "yensalela ephansi".

Siyenqaba uketshezi olunodayi abengeziwe, iphunga elimnandi, noma ama-surfactants. Odayi bayawohloka ngaphansi kwe-UV nokushisa—okushiya ifilimu ephuzi kumalensi namaphrojektha. Amakha afihla igesi kodwa ungakuyeki. Ama-surfactants anciphisa ukungezwani okungaphezulu kakhulu, okwenza inkungu iwe ngaphambi kokufinyelela izinga lezethameli.

Abanye bangase baphikise uketshezi lwenkungu olujwayelekile “olwesekelwe emanzini” luphephile futhi lushibhile. Nokho, “isisekelo samanzi” sisho kuphela ukuthi amanzi akhona—hhayi ukuthi amanzi awumthombo oyinhloko. Izingxube ze-Propylene glycol/zamanzi zibusa imakethe, kodwa izilinganiso zibalulekile. I-70/30 PG/ingxube yamanzi isebenza ngokuthembekile. Ingxube engu-40/60 ibilisa ngokungalingani, ikhafule, futhi ishiye amadiphozithi amaminerali uma amanzi kampompi ayesetshenziswa ekukhiqizeni.

Ukufanisa Uketshezi Nomshini Wakho—Nendawo Yakho

Akuyona yonke imishini yenkungu elinganayo. Amayunithi amadala anamakhoyili okushisa e-nickel-chrome abekezelela ukucaciswa koketshezi olubanzi. Amayunithi esimanje e-ceramic-core adinga ukubekezelelana okuqinile. Sibhala lokhu nsuku zonke: lapho sikhipha izinto ze-Robe BMFL Beam eduze nenkungu embukisweni we-Shenyang Olympic Sports Center, ukusika kwe-boam kwakudinga inkungu eminyene kakhulu, ezinza kancane. Uketshezi olujwayelekile lunikeze ukubonakala kwemizuzwana engu-12. Inhlanganisela yethu yangokwezifiso engu-65/35 triethylene glycol/propylene glycol inwebe yafika kumasekhondi angu-37—ngaphandle kokwanda kokusetshenziswa koketshezi.

I-Altitude ishintsha yonke into. Ku-1,500m ngaphezu kwezinga lolwandle (okuvamile entshonalanga yeChina), amaphuzu abilayo ayehla. Uketshezi olwakhelwe ukusetshenziswa ezingeni lolwandle luyahwamuka kusenesikhathi endleleni yokudla—okubangela i-cavitation kanye nokukhuphuka komfutho. Manje sitokha okuhlukile okubili: eyodwa ilinganiselwe ngo-≤500m, enye yaqinisekiswa kufika ku-2,200m.

Izinga lokushisa eleqile lidinga ukuzivumelanisa nezimo. Ngaphansi kuka-10°C, uketshezi olujwayelekile luyajiya. Okukhiphayo okwehlayo. Ukushisa i-reservoir kusengaphambili kuyasiza—kodwa kuphela uma uketshezi luhlala luzinzile. Sihlole izinhlobo eziyi-17 ku -5°C. Ukugeleza okune kuphela okugcinwe endaweni eyi-0.3mm ngaphandle kokufudumala kwangaphambili. Bobane basebenzise i-glycerin esters eguquliwe—hhayi i-glycerin eqondile.

Ukukhetha Uketshezi Lwentuthu Kuyisinqumo Sesistimu—Akuyona Into Yomugqa

Ukukhetha uketshezi lwentuthu kuxhumene ngqo nohlelo lwakho lokulungisa, ukuba semthethweni kwewaranti, nokuthembeka kokudala. Ukusebenzisa uketshezi okungewona we-OEM kwehlisa iziqinisekiso zengxenye eshisayo yabakhiqizi—hhayi ngenxa yokwethembeka komkhiqizo, kodwa ngenxa yokuthi amaphethini ezinsalela akwenza kube lula ukuhlaziya ukwehluleka. Silandelela lokhu: imishini esebenzisa isilinganiso soketshezi oluyinsalela ephansi eqinisekisiwe yezinyanga eziyi-18 phakathi kokuhlanzwa kwemibhobho. Labo abasebenzisa uketshezi olungaqinisekisiwe isilinganiso sezinyanga ezi-4.3.

Izindleko akuyona nje intengo ngelitha. Kungumsebenzi ukulungisa imigqa, isikhathi sokuphumula phakathi nemikhosi, izingxenye ezishintshayo, kanye nengozi yesithunzi lapho inkungu ihluleka ukusebenza phakathi nokusebenza. Uketshezi luka-$28/litre olunweba impilo ye-heater ngo-300% luyazikhokhela emicimbini engaphansi kwesithupha.

I-Shenyang Fei Ya Water Art Landscape Engineering Co., Ltd. ihlanganise izinhlelo zenkungu emithonjeni engaphezu kwe-100 kusukela ngo-2006—kusuka ezimpompini ezingaphansi kweqanda ze-Harbin Ice Festival kuya kumakhethini enkungu avumelanisiwe e-Dubai Fountain. Konke ukuthunyelwa kuqala ngokuqinisekisa uketshezi. Wonke amaklayenti athola ishidi eliwuketshezi—hhayi incwajana. Ngoba inkungu ayiwona umkhathi. Ubunjiniyela obunembayo, obumisiwe emoyeni.

Ukukhetha Uketshezi Lwentuthu kuchaza lokho izethameli zakho ezikubonayo—nokuthi ithimba lakho likugcine ini. Khetha uketshezi olusebenza ngendlela efanayo phakathi kwamabili njengoba kwenzeka emini, emvuleni noma ekushiseni okomile, bonisa ngemva kombukiso. Lokho akuwona umbono. Lokho kuyisiyalo sokusebenza.
