Yonke insimu ekujuleni komphefumulo ikholelwa ukuthi kulo nyaka izitshalo zakhe zizoxoshwa yizilokazane. Kodwa uma ulinganisela ngokucophelela wonke amathuba ukuthi ungagcina isivuno kusuka ekuhlaselweni kwezinambuzane, ngaphandle kokusebenzisa amakhemikhali akhethekile, ungaqonda ukuthi awunakwenzeka ukuphumelela. Indlela engcono kakhulu yokwelapha izitshalo ezifweni noma izinambuzane iyaphula. Ake sizame ukubona ukuthi iyiphi i-unit evumelana kahle nesimo sakho.
Kungani ukhetha abaphampu bepompo?
Abalimi abaningi basebenzisa iprayipi-type sprayers epulazini. Yiqiniso, lokhu akulona uhlobo olulodwa lwale divayisi, kodwa ngenxa yokuthi kulula ukuyisebenzisa futhi kulula ukusebenzisa, yizona ezithandwa kakhulu. Ngenxa yezici ezikhethekile zedivayisi, i-sprayer yebhuku idinga ukucindezelwa komsebenzisi okuqhubekayo kumbindi oqhuba ipompo, okuyinto engathinteki kakhulu lapho kudingeka khona indawo enkulu. Ngaphezu kwalokho, isispirisi se-hydraulic esine-drive manual sincane kakhulu kunezimo ezifana nepompo. Amandla ayo afinyelela amalitha ayisikhombisa, futhi amapulisi angaphakamisa amakhemikhali angama-20 (i-knapsack sprayer).
I-Knapsack sprayer noma ipompo ngesandla?
Ngokomgomo wokusebenza, iningi lalabo abafipulisi baqhutshwa yi-pump. Igama elithi "ipompo" lenza isimiso sokujoya umoya emgodini ngosizo lwepompo. Abafutho bashayi bezinhlobo ezinjalo banezimpompo ngepompo, okushiwo ukucindezelwa okudingekile kuqhutshelwa ukusebenza okujwayelekile kwedivayisi. Isici sabo esihlukanisayo siyikhono elikhulu le-tank, elifinyelela amalitha angu-12. Ukuze insimu yepompi yesandla isetshenziselwe ukuhamba lapho igcwele, ngokuvamile ifakwe "harness". Ngesizo salo akulula ukuphatha leyunithi, ngisho nalapho igcwele.
Olunye uhlobo lwabaprayipi luhlobo lwepayipi le-knapsack pump. Igama layo livela ekuthuthweni kweyunithi ngenkathi kuqhuma inqubo. Umshini wokufafaza onjalo uphelelwa ngemuva njengesikhumba, ngoba ifakwe isitsha samakhemikhali angaphezu kwamalitha angu-20. I-drive yayo yokugudluza imishini ivame ukuqhutshwa yi-lever ngakwesokunene se-knapsack ngokunyakaza okuphezulu nokuya phansi. Njengoba usuqede ukucindezela okudingekile, kungenzeka ukuba udlule ukuze uphefe. Isici esihlukile salolu sprayer yindlela yokusebenza ewusizo futhi elula ekucubunguleni izindawo ezinkulu (akudingekile ukwengeza amakhemikhali ethandini).
Ungakhetha kanjani futhi usebenzise sprayer?
Ukukhethwa kwe-sprayer kufanelekile ukwenza, ngokusekelwe kumsebenzi ozokwenziwa. Uma kuncane, ungathenga uhlobo lwesandla sophethiloli wensimbi ngekhwalithi yamalitha angamahlanu. Yebo, uma ungumnikazi ojabulisayo wesakhiwo sezingxenye eziyi-10 noma ezingaphezu kwekhulu, bese ukhetha kumaprayipi ngamandla okungenani amalitha ayi-10. Ungakwazi ukubala ivolumu le-tank edingekayo usebenzisa isibonelo esilandelayo:
- Amalitha angu-10 amakhemikhali adliwe ngomuthi omdala omdala;
- ukuphathwa komuthi omncane, amalitha amabili anele;
- ukucubungula isihlahla esisodwa kuyilitha elilodwa lesisombululo;
- Ukucubungula imifino kuzothatha amalitha amabili ngamakhilomitha ayikhulu engamamitha.
Esinye isici ekukhetheni kuyinani. Ungakhethi onobuhle kakhulu (ikhefu, njengabo bonke abanye), kodwa futhi akudingeki ukuthi uthenge eshibhile. Khetha imodeli kusukela kusigaba samanani entengo futhi ngeke ulahlekelwe.
Ekuphetheni, ngifuna ukukhumbula izinyathelo eziyisisekelo zokuphepha, ngoba abalimi abaningi abanalo ulwazi lokuthi bangasebenzisa kanjani ipompi noma olunye uhlobo lwesipuni. Ngokuvamile, zonke ziphela nge-poisoning eqinile. Qinisekisa ukusebenzisa imishini yokuzivikela, efaka ikhanda elikhethekile, amagilavu nomphefumula. Ngemuva kokuqeda ukwelashwa, qiniseka ukuthi ususa isipirisi ngamanzi ahlanzekile.
