Mokhoa oa ho Lekola Phetoho ea Khatello (Mehato e 6)
Tse ka hare
Qetellong ea sengoloa sena, u tla tseba ho lekola sesebelisoa sa khatello habonolo le ka katleho.
Li-switches tsohle tsa khatello li tlameha ho ba le moeli oa libaka tse shoeleng bakeng sa ts'ebetso e nepahetseng. Sehlopha se shoeleng ke phapang pakeng tsa khatello ea khatello le ho oa ho beha lintlha, tse ka fumanoang habonolo. Sebaka se shoeleng se beha moeli oa ho etsa le ho senya likhokahano tsa motlakase sesebelisoa. Joaloka monna ea sebetsang ka matsoho, hangata ke tlameha ho hlahloba le ho rarolla mathata a li-deadband ho lisebelisoa tse kang lihatsetsi tsa HVAC. Ho tseba moeli oa "deadband" oa switch ea hau ke senotlolo sa ho utloisisa le ho rarolla bothata ba sesebelisoa sa hau sa khatello le lisebelisoa tse ling tsohle tseo e li laolang.
Ka kakaretso, mokhoa oa ho lekola hore na sesebelisoa sa hau sa khatello se na le moeli oa sebaka se shoeleng se bonolo.
- Hakolla sesebelisoa sa khatello ho sesebelisoa seo se se laolang.
- Lekola switch ea khatello ka calibrator ea DMM kapa calibrator efe kapa efe e loketseng.
- Hokela sesebelisoa sa khatello mohloling oa khatello joalo ka pompo ea letsoho e hokeletsoeng mochining oa ho lekanya khatello.
- Eketsa khatello ho fihlela phetoho ea khatello e fetoha ho tloha ho bula ho ea ho e koetsoeng.
- Ngola boleng bo ntseng bo eketseha ba khatello e behiloeng
- Butle-butle fokotsa khatello ho fihlela phetoho ea khatello e fetoha ho tloha ho bula ho ea ho e koetsoeng.
- Ngola boemo ba khatello ea ho theoha
- Bala phapang lipakeng tsa khatello e nyolohang le e theohang ka li-pints tse ntle ka ho fetisisa
Ke tla teba ho sena.
Ho hlahloba phetoho ea khatello
Ho hlahloba mochine oa khatello hase mokhoa o thata. Ts'ebetso e latelang e tla u thusa ho lekola sekhahla sa khatello ea khatello ea maikutlo ka nepo.
Hlophisa sesebelisoa sa hau
Pele, o hloka ho theha sesebelisoa; mehato e latelang e tla thusa:
Mohato oa 1: Hakolla sesebelisoa sa khatello
Hakolla sesebelisoa sa khatello ho sesebelisoa seo se se laolang ka hloko le butle. Lisebelisoa tse laoloang ke li-switches tsa khatello li kenyelletsa li-HVAC, lipompo tsa moea, libotlolo tsa khase le tse ling.
Mohato 2: Khatello Switch Calibration
Tekanyo e nepahetseng ea sesebelisoa ke ea bohlokoa ho bona le ho lokisa liphoso ho switch point le deadband. Ho feta moo, calibration e boloka nako ka ho fokotsa palo ea lisebelisoa tse sebelisoang. Ke khothaletsa ho khetha calibrator e nepahetseng ho iketsetsa mokhoa oa ho lekanya. (1)
Joale hokela calibrator (kapa DMM) ho li-terminals tse tloaelehileng le tse tloaelehileng tse bulehileng tsa switch ea khatello.
Calibrator ea DMM e lekanya "potoloho e bulehileng". Hape, etsa bonnete ba hore calibrator ea DMM e khona ho sebetsana le voltage e lekantsoeng - ha e lekanya motlakase oa AC.
Mohato oa 3 Hokela switch ea khatello mohloling oa khatello.
O ka hokela sesebelisoa sa khatello ho pompo ea letsoho e hokelletsoeng ho tekanyo ea khatello.
Khatello e ntseng e eketseha
Mohato oa 4: Eketsa khatello ea mochine oa khatello
Eketsa khatello ea mohloli ho boemo ba ho fetola khatello ho fihlela (mochine oa khatello) o fetola boemo ho tloha "koetsoe" ho "bula". Ngola boleng ba khatello hang ka mor'a hore DMM e bontše "potoloho e khutšoanyane"; leha ho le joalo, ha u sebelisa calibrator, e tla rekota boleng - ha ho hlokahale hore u e tlalehe ka letsoho.
Khatello ea ho oela
Mohato oa 5: Butle-butle fokotsa khatello ea relay
Phahamisa khatello ho khatello e phahameng ea switjha. Ebe butle-butle fokotsa khatello ho fihlela phetoho ea khatello e fetoha ho tloha ho koaloa ho ea ho bula. Ngola boleng ba khatello. (2)
Palo ea sehlopha se shoeleng
Mohato oa 6: Bala Tekanyo ea Deadband
Hopola litekanyetso tse latelang tsa khatello tseo u li tlalehileng mehatong e fetileng:
- Seta Khatello - E ngotsoe ha khatello e phahama.
- Seta khatello - E ngotsoe ha khatello e theoha.
Ka linomoro tsena tse peli, u ka bala khatello ea deadband u sebelisa foromo:
Khatello ea sehlopha se shoeleng = Phapang pakeng tsa ho phahama ha khatello ea khatello le ntlha ea ho theoha ha khatello.
Liphello tsa boleng ba sebaka se shoeleng
Sepheo se seholo sa ho ba le sehlopha se shoeleng (se fapaneng pakeng tsa ho eketseha ha khatello le lintlha tse fokotsehang) ke ho qoba ho phunya. Sehlopha se shoeleng se hlahisa boleng ba threshold bakeng sa ha tsamaiso ea motlakase e lokela ho bula kapa ho koala.
Kahoo, bakeng sa ts'ebetso e nepahetseng, sesebelisoa sa khatello se tlameha ho ba le sebaka se shoeleng. Haeba u se na bendi e shoeleng, switch ea hau ea khatello e fosahetse 'me e hloka ho nkeloa sebaka kapa ho lokisoa, ho latela tšenyo.
Ho akaretsa
Joalokaha ho se ho boletsoe, khatello ea menyako ea sebaka se shoeleng e tlameha ho ba ea bohlokoa bakeng sa ts'ebetso e nepahetseng ea sesebelisoa sa khatello le sesebelisoa seo e sebetsang ho sona. Ts'ebetso e bonolo: theha switch ea khatello, e hokahane le sesebelisoa, eketsa khatello, fokotsa khatello, rekota litekanyetso tsa ho beha khatello 'me u bale moeli oa deadband.
Ke lumela hore mehato le likhopolo tse qaqileng tsa tataiso ena li tla u thusa hore u leke mochine oa khatello ka tsela e bonolo le ho utloisisa bohlokoa ba oona.
Sheba tse ling tsa lingoliloeng tsa rona tse ka tlase.
- Mokhoa oa ho hokela switch ea 3-wire AC khatello
- Mokhoa oa ho lekola sesebelisoa sa lebone ka multimeter
- Ke terata efe e hokelang libeteri tse peli tsa 12V ka tjantjello?
