Le woluvo amanzi: Ukuhlelwa, umsebenzi, inkcazo kwefowuni

Supply kwinqanaba amanzi asetyenziswa ukulawula kwinqanaba ulwelo kwi matanki ezahlukeneyo. Ezi zixhobo zisetyenziselwa ulawulo konogumbe, ulawulo amanzi ekukhuliseni amadama kunye namachibi; ekhaya, ukuba zisetyenziswa ukuhlamba koomatshini, okuququzelela iinkqubo zokuzisa amanzi kunye neenkqubo zokufudumeza, njalo njalo. d.

Ukuhlelwa nenkcazo

Ezi zixhobo kuxhomekeke indlela womlinganiselo lungohlulwa lube contact and non-contact. Le woluvo amanzi lohlobo yokuqala imi ngqo eludongeni itanki, oko sokuyivula abafowunelwa ngalo mzuzu zokufezekisa inqanaba engamanzi apho ibekwe. Ukongeza, umgangatho womlinganiselo amanzi kwenziwa ezi ndlela zilandelayo :. Capacitive magnetic, enombala, cuke, njl Le woluvo enombala kwamanzi kuye akukho ezihambayo, ukuba zixhonywe kudonga itanki kwaye izakufunyanwa xa zifikelela kwinqanaba kwangaphambili. okubonakalayo ray uphazamisa ibangela utshintsho uphawu kwiziphumo kwefowuni.

Le sensor amanzi (edadayo), sisixhobo ngobuciko jikelele uluhlu olubanzi izicelo ezahlukeneyo ezifuna imilinganiselo echanileyo kakhulu flow fluid. izixhobo ezinjalo olulodwa kunye multi-level, kwakunye yomgama (analog).

Isivamvo sakufutshane level amanzi ukusebenza kunye ulwelo ezahlukeneyo, izinto eziqinileyo kunye nezinto kunye shiyana yetyhefu kunye viscosity. izixhobo ezinjalo zahlulwe izixhobo capacitive kunye cuke.

izixhobo contact (Level) aba ukunxibelelana engamanzi, xa kulinganiswa. Basenokuba ukuxakeka emanzini (ezifana radar okanye hydrostatic) okanye okulungiswe eludongeni itanki ubude kwangaphambili (ifolokhwe optical izixhobo vibratory). Ba enombala, piezoelectric ifolokhwe, radar okanye radar, hydrostatic kunye nefayibha optic.

Indlela yokwenza isivamvo inqanaba lamanzi itanki?

Ukuba awanelisekanga iimveliso ezithengiswa ezivenkileni, zama ukwenza sixhobo ngokwabo, ingakumbi kuba ilula. Zomenzi, ezicetyiweyo ingqalelo yakho, kusetyenziswa ukulawula kwinqanaba ulwelo ngokwezikhundla ezahlukeneyo. Ngesi sixhobo uphawu senziwa okanye off na impompo yamanzi okanye umkhosi esandleni sakhe. Le fowuni i DC msindo elula, leyo kwakheka kwi transistors ezimbini. Trimmer ikuvumela ukuba ufake uvakalelo eyimfuneko ifowuni. Transistors ayakhuselwa semiconductor diode. Izixhobo ibonisa ukuba LED olunye elahliweyo kwi sokuqokelela le transistor yokuqala. Ukuba bahlanganise kufuneka resistors (220 kOhm, 10 kOhm. - iiyunithi 3, 1.2 ohms) thina, capacitor One (470 uF / 50 V), transistors ezimbini (VS547), diode (1N4001) kwaye enye LED. Loo icebo sisebenzisa ombane ngqo 6-15V yaye zisebenzisa umsinga wombane-75 Ma.

Le woluvo zingasetyenziswa njenge ipleyiti fiberglass ngefoyile (10 x 50 mm). Kufuneka imiselwe ku-3 mm ngaphakathi alumuniyam eliqinileyo.

isiphelo

UPawulos, Omet, ukuba izixhobo ezinjalo luncedo kakhulu, ingakumbi kwicandelo labucala. Lithethe ityala ngokwakho: le woluvo kufakwa itanki ukuba ishawa okanye ibhafu, xa ukunkcenkceshela igadi yombutho, kwakunye iinkqubo zokugcina Amanzi kwikhaya lakho.
