Lub twj tso kua mis yog lub tshuab tshwj xeeb rau kev tsim thiab tswj cov dej ntws hauv cov kav dej rau ntau lub hom phiaj. Txhawm rau kom lub twj tso kua mis ua haujlwm, nws yuav tsum tau txuas nrog lub tsav tsim nyog. Drives muab faib ua phau ntawv, txhua yam, hluav taws xob. Lub tshuab txuas nrog lub tshuab hluav taws xob yog lub twj tso kua mis hluav taws xob (feem ntau nyob rau hauv ob qho tib si kev lag luam thiab hauv tsev).
Basic pump Requirement
hom kev ua haujlwm ntawm lub twj tso kua mis yuav tsum muab tag nrho cov kev xav tau rau lub network uas nws suav nrog. Feem ntau, qhov no yog qhov "on-off" muaj nuj nqi (thaum sau lossis tso tawm cov kua hauv cov thawv), tswj lub siab xav tau nrog kev nce lossis txo qis hauv cov khoom siv, kev ua haujlwm tsis cuam tshuam hauv kev ncig, kev kaw thaum muaj xwm txheej ceev, kev sib txuas ntawm lub twj tso kua mis thaub qab.. Kev ua raws li cov kev cai no yog tus yuam sij rau kev ua haujlwm raug nqi, ua kom lub neej ntawm cov cuab yeej siv tau.
Dab tsi yog qhov automation system muaj
Txhawm rau tswj cov kev khiav hauj lwm hom, automation rau twj yog tsim, uastshem tawm kev cuam tshuam tib neeg hauv kev ua haujlwm. Feem ntau, cov txheej txheem tswj hwm muab kev hloov pauv mus rau "kev qhia hom" thaum muaj xwm txheej ceev (piv txwv li, qhov tsis ua haujlwm ntawm ib qho sensor uas yog ib feem ntawm automation). Raws li txoj cai, automation rau cov twj tso kua mis suav nrog cov hauv qab no:
1. Lub siab hloov pauv yog ib qho khoom siv aneroid-membrane uas, thaum muaj qee qhov siab mus txog, kaw lossis qhib cov hluav taws xob tswj hluav taws xob.
2. Electrocontact pressure gauges (EKM) nrog rau cov pab pawg txav tau thiab ruaj khov ntawm el. hu rau.
3. Float system (ntsia hauv cov thawv ntim) nrog el. hu rau.
4. Siab transducers nrog strain gauge txuas hniav uas hloov tsis kam tso cai rau tam sim no ntws raws li qhov system siab hloov.
5. Mechanical lossis hluav taws xob ntsuas ntawm qhov ntim ntawm cov kua haus, uas teeb tsa lub teeb liab hauv kev tswj xyuas hluav taws xob thaum lub ntim ntim tau mus txog.
6. Zaus converters ntawm cov khoom tam sim no el. Pump motor.
Cov ntsiab lus 1, 2, 4, 5 raug ntsia ncaj qha (txiav) rau hauv cov kav dej. Pump automation kuj muaj xws li:
- electromagnetic starters;
- email Hloov cov tswv yim rau cov twj tso kua mis standby;
- hloov khoom siv hloov mus rau "AUTO" lossis "MANUAL" hom;
- lub teeb fittings taw qhia kev ua haujlwm ib txwm muaj, kaw thaum muaj xwm txheej ceev, hloov mus rau qhov tshwj tseg, thiab lwm yam.;
- khoom siv tiv thaiv hluav taws xob twj tso kua mis motors, tswj circuits.
Cov khoom siv saum toj nomounted nyob rau hauv lub twj tso kua mis tswj txee raws li qhov yuav tsum tau ntawm PUE (Electrical Installation Rules).
Txoj Cai Ua Haujlwm
Pump automation ua haujlwm li cas? Feem ntau hom ntawm cov twj tso kua mis tawm. Piv txwv li: lub reservoir (tank) yog ntim nrog cov kua mus rau theem uas yuav tsum tau, thaum lub float system kaw (qhib) coil Circuit Court ntawm lub electromagnetic oob khab, uas tig rau (tawm) lub twj tso kua mis. Tib yam tshwm sim thaum lub ntab ntab qis mus rau ib theem. Los ntawm tib txoj cai, automation ua haujlwm los ntawm kev hloov siab, el. hu rau manometer, suav ntawm ntim ntawm cov kua siv. Yuav kom tswj tau qhov kev xav tau, txoj kev hloov pauv zaus ntawm kev sib hloov ntawm lub zog hluav taws xob yog siv. lub cev muaj zog. Hom no yog muab los ntawm lub zaus converter ntawm qhov tam sim no muab cov el. twj. Qhov zaus ntawm qhov hloov pauv hloov nyob ntawm theem ntawm lub teeb liab los ntawm lub siab sensor. Kev txuas ntxiv ntawm cov kua ncig hauv lub kaw lus kaw (qhov no yog cov cua kub feem ntau) yog xyuas kom muaj lub twj tso kua mis thaub qab, uas tau qhib los ntawm kev hloov pauv xwm txheej kub ntxhov thaum lub twj tso kua mis loj tsis ua haujlwm.
