Lesi sihloko sihlola umehluko wezobuchwepheshe, izinzuzo zokusebenza, ukufaneleka kwemvelo, kanye nezinhlelo zokusebenza zokushintshwa kwe-float kanye nokushintsha kweleveli. Ukwengeza, inikeza isiqondiso sendlela yokukhetha idivayisi efaneleke kakhulu yohlelo lokusebenza olunikeziwe, iqinisekisa ukuthi isisombululo esikhethiwe sinikeza ukusebenza okuphelele nokuthembeka kwesikhathi eside. Ekupheleni kwalesi sihloko, abafundi bazoqonda ukuthi iyiphi idivayisi efanele izidingo zabo ezithile kanye nezici ezithonya ukutholwa kwezinga elinembile.
1. Ukuqonda Okuyisisekelo
1.1 Yini i-Float switch?
Iswishi ye-float iyithuluzi elilula elisetshenziselwa ukuthola ubukhona noma ukungabikho koketshezi endaweni enqunywe kusengaphambili. Isebenza kusetshenziswa ukuntanta okunyakazayo okuhamba kuqonde phezulu ngeleveli yoketshezi. Lapho iflothi ifinyelela endaweni emisiwe, icupha iswishi, engasebenzisa amaphampu, ama-alamu, noma amasistimu okulawula.
Amaswishi okuntanta ngokuvamile asetshenziselwa:
Ukulawula iphampu emathangini amanzi noma kuma-reservoirs
Ama-alamu asezingeni eliphezulu noma aphansi
Imisebenzi eyisisekelo ezenzakalelayo lapho kudingeka khona ukutholwa kwezinga lephoyinti
Ubulula bokushintshwa kwe-float kungenye yezinzuzo zabo ezibalulekile. Ngokuvamile azidingi izinto zikagesi eziyinkimbinkimbi noma ukulinganisa, okuzenza zibe ukukhetha okubiza izindleko zezinhlelo zokusebenza eziqondile. Isenzo somshini siqinisekisa ukushintshwa okuthembekile kokusebenza ngisho nalapho kungabikho izingxenye zikagesi. Kodwa-ke, ubulula bazo buphinde bubeke imikhawulo, ikakhulukazi mayelana nokunemba, ukuzwela ekunyakazeni koketshezi, kanye nokuvumelana nezimo eziyinselele.
Amaswishi okuntanta ngokuvamile akhiwa ngezinto ezimelana nokugqwala njengensimbi engagqwali, i-polypropylene, noma i-PVC, ezivumela ukuthi zisebenze oketshezini oluphakathi nendawo noma olunolaka kancane. Ukusebenza kwabo kuqondile: njengoba uketshezi lukhuphuka noma luwa, i-float ihamba nayo, ibangele ukuthintana kwamagnetic noma komshini. Lo mklamo wenza amaswishi e-float athembeke kakhulu ukuze atholakale kalula ekuvuleni/okuvaliwe kodwa angafaneleki kakhulu ezinhlelweni zokulawula ezinembile noma eziyinkimbinkimbi.
1.2 Kuyini Ukushintshwa Kwezinga?
A ukushintshwa kweleveli , ngomqondo obanzi, kubhekisela kunoma iyiphi idivayisi ethola ileveli yoketshezi noma into eyinqwaba endaweni ethile. Ngokungafani nokushintshwa kwezinto ezintantayo, ukushintsha kwezinga kuhlanganisa ubuchwepheshe bokuzwa obuningi, okuhlanganisa imishini, i-capacitive, i-optical, i-vibrating/tuning fork, kanye namadivayisi asekelwe ku-conductive/electrode.
Ukushintsha kwamaleveli kuklanyelwe izinhlelo zokusebenza ezifuna kakhulu, zinikeza ukunemba okuthuthukisiwe, izikhathi zokuphendula ngokushesha, kanye nokuvumelana nezimo kwemvelo okukhulu. Zisetshenziswa kakhulu ku:
