Pafupifupi alimi onse tsopano amapopera mbewu ndi zinthu zoteteza zomera, choncho kugwiritsa ntchito bwino sprayer ndi kusankha mphuno yoyenera kumafunika kuonetsetsa kuti kuphimba bwino ndi mankhwala ochepa kwambiri.Izi sizimangochepetsa kukhudzidwa kwa chilengedwe, komanso zimapulumutsa ndalama.
Pankhani yosankha nozzle yoyenera ya sprayer m'munda wanu, vuto lalikulu ndilakuti pali zosankha zambiri.Pali kuchulukirachulukira kwa ma nozzles ndipo ndizowona kuti pali zosankha zambiri, kotero kupeza mphuno yoyenera kungakhale kovuta.
M'malo mwake, zopangidwa ndi nozzle pamsika ndizabwino kwambiri.Mwa opanga asanu ndi limodzi kapena apamwamba, onse amapanga zinthu zabwino zokhala ndi magwiridwe antchito ofanana.Ngati wosuta akufunafuna mankhwala abwino kwambiri a nozzle, kapena ali ndi ntchito yamatsenga, sipangakhale phokoso loterolo nkomwe.Kapena, ngati mukumva kapena kuwona chopangidwa ndi nozzle chomwe chimati chili ndi mphamvu zamatsenga, mutha kuchichotsa pamndandanda wachidule.
Malinga ndi akatswiri ambiri oteteza zomera ndi mankhwala ophera tizilombo, nthawi zambiri pamakhala mfundo ziwiri zofunika kuziganizira posankha mphuno: dontho loyenera kukula ndi mphuno yoyenera.
Choyamba, pezani mphuno yomwe imatulutsa kukula koyenera kwa dontho lomwe likugwiritsidwa ntchito.Nthawi zambiri, kupopera mbewu mankhwalawa kumagwira ntchito bwino ndi pafupifupi zinthu zonse zoteteza mbewu ndikuchepetsa kugwedezeka.Zomwe wogwiritsa ntchito akuyenera kuchita ndikuwerenga pepala lodziwika bwino la opangira nozzle kuti amvetsetse mtundu wa kupopera.Kwa ambiri opanga ma nozzles, zomwe amapangira zitha kupezeka pa intaneti.
Gawo lachiwiri ndikusankha nozzle kukula kwake.Ndi chidwi chokulirapo pamakina a PWM, kukula kwa nozzle kumakhala kofunika kwambiri.Kusinthasintha kwa pulse ndi njira yatsopano yoyezera kutuluka kwa madzi kuchokera pamphuno.
Dongosolo la PWM limagwiritsa ntchito chitoliro chopopera chachikhalidwe chokhala ndi boom imodzi yokha ndi nozzle imodzi pamalo.Kuthamanga kwamadzi kudzera mumphuno iliyonse kumayendetsedwa ndikutseka pang'onopang'ono komanso mwachidule ndi ma valve solenoid.Kuthamanga kwafupipafupi ndi 10 Hz, ndiko kuti, valavu ya solenoid imatseka mphuno 10 pa sekondi iliyonse, ndipo nthawi yomwe mphuno ili "pa" imatchedwa kuyendayenda kwa ntchito kapena kugunda kwapakati.
Ngati ntchito yozungulira yakhazikitsidwa ku 100%, zikutanthauza kuti nozzle yatsegulidwa kwathunthu;Kuzungulira kwa ntchito kwa 20% kumatanthauza kuti valavu ya solenoid imatseguka 20% yokha ya nthawiyo, zomwe zimapangitsa kuti pakhale 20% ya mphamvu ya nozzle.Kutha kuwongolera kuzungulira kwa ntchito kumatchedwa pulse wide modulation.Pafupifupi onse opopera mankhwala m'mafakitale akuluakulu masiku ano ndi makina a PWM, ndipo pafupifupi gawo limodzi mwa magawo atatu mpaka theka la omwe amagwira ntchito m'minda yaulimi ndi makina opopera mankhwala a PWM.
Izi zitha kuwoneka zovuta, ndipo wogwiritsa ntchito akakayika, ndi bwino kukaonana ndi wogulitsa nozzle wapafupi kapena katswiri woteteza mbewu kuti atsimikizire kuti mphuno yoyenera ikugwiritsidwa ntchito, kupulumutsa nthawi ndi ndalama.
