Cishe bonke abalimi manje bafafaza izitshalo ngemikhiqizo yokuvikela izitshalo, ngakho-ke ukusetshenziswa okufanele kwesifutho nokukhethwa komlomo ofanele kuyadingeka ukuze kuqinisekiswe ukumbozwa okusebenzayo ngenani elincane lamakhemikhali.Lokhu akugcini nje ukunciphisa umthelela wemvelo, kodwa futhi kusindisa izindleko.
Uma kuziwa ekukhetheni umbhobho ofanele wesifutho sakho sasensimini, inkinga enkulu ukuthi ziningi kakhulu ongakhetha kuzo.Kukhona ukugcwala ngokweqile kwemibhobho futhi kuyiqiniso ukuthi kunezinketho eziningi kakhulu, ngakho ukuthola umbhobho olungile kungaba inselele.
Eqinisweni, imikhiqizo ye-nozzle emakethe ingeyekhwalithi enhle kakhulu.Kubakhiqizi abakhulu abayisithupha noma ngaphezulu, bonke benza imikhiqizo emihle ngokusebenza okufanayo.Uma umsebenzisi efuna umkhiqizo we-nozzle ongcono ngokuphelele, noma enohlobo oluthile lomsebenzi wemilingo, kungenzeka ungabi khona nhlobo umbhobho onjalo.Noma, uma uzwa noma ubona umkhiqizo we-nozzle othi unamandla omlingo, ungawususa ngokuphelele ohlwini olufushane.
Ngokusho kochwepheshe abaningi bokuvikela izitshalo kanye nezibulala-zinambuzane, ngokuvamile kunamaphuzu amabili asemqoka okufanele unake lapho ukhetha umlomo wombhobho: ithonsi losayizi olungile kanye nombhobho olungile.
Okokuqala, thola umlomo wombhobho okhiqiza usayizi wamaconsi ofanele womkhiqizo osetshenziswayo.Ngokuvamile, isifutho esiqinile sisebenza kahle cishe nayo yonke imikhiqizo yokuvikela izitshalo futhi sinciphisa ukukhukhuleka.Konke okudingeka akwenze umsebenzisi ukufunda ishidi lokucaciswa kwesifutho somkhiqizi we-nozzle ukuze aqonde ikhwalithi yesifutho.Kubakhiqizi abaningi abakhulu be-nozzle, imininingwane yomkhiqizo wabo ingatholakala ku-inthanethi.
Isinyathelo sesibili ukukhetha usayizi olungile umlomo wombhobho.Ngentshisekelo ekhulayo ezinhlelweni ze-PWM, usayizi wombhobho uba obaluleke kakhulu.Ukuguquguquka kobubanzi be-Pulse kuyindlela entsha yokulinganisa ukugeleza koketshezi olusuka emlonyeni.
Uhlelo lwe-PWM lusebenzisa ipayipi lendabuko lokufutha eline-boom eyodwa kuphela nombhobho owodwa endaweni ngayinye.Ukugeleza koketshezi kubhobo ngalinye kulawulwa ngokuvala kancane kancane imibhobho ngamavalvu e-solenoid.Imvamisa yokushaya kwenhliziyo evamile ngu-10 Hz, okungukuthi, ivalve ye-solenoid ivala umlomo izikhathi ezingu-10 ngomzuzwana, futhi ubude besikhathi lapho umlomo wombhobho usendaweni "uvuliwe" ubizwa ngokuthi umjikelezo wemisebenzi noma ububanzi be-pulse.
Uma umjikelezo womsebenzi usethelwe ku-100%, kusho ukuthi umlomo wombhobho uvuleke ngokugcwele;umjikelezo womsebenzi wama-20% usho ukuthi i-valve ye-solenoid ivuleka kuphela u-20% wesikhathi, okuholela ekugelezeni okungaba ngu-20% womthamo womlomo.Ikhono lokulawula umjikelezo wokusebenza libizwa ngokuthi i-pulse width modulation.Cishe zonke izifutho zasemasimini ezimbonini ezinkulu namuhla ziyizinhlelo ze-PWM, futhi cishe ingxenye eyodwa kwezintathu kuya kuhhafu yalezo ezisebenza emasimini amasistimu wokufafaza we-PWM.
Lokhu kungase kubonakale kuyinkimbinkimbi, futhi uma umsebenzisi engabaza, kungcono ukuthintana nomthengisi wendawo yangakini wombhobho noma uchwepheshe wokuvikela izitshalo ukuze uqinisekise ukuthi kusetshenziswa umlomo wombhobho olungile, konga isikhathi nemali.
