Tsis Siv Neeg twj: lub tau thiab txoj ntsiab cai ntawm cov lag luam

Twj tso kua mis - ib tug tshwj xeeb mechanism rau cov tsim thiab tswj kua ndlwg nyob rau hauv pipelines rau ntau lub hom phiaj. Nyob rau hauv kev txiav txim rau lub twj tso kua mis mus ua hauj lwm, nws yuav tsum tau kev cob cog rua rau ib tug tsim nyog tsav. Lub drives raug muab faib mus rau hauv xoob, mechanical, hluav taws xob. Lub mechanism uas yog kev cob cog rua rau lub electric tsav - yog ib tug hluav taws xob twj tso kua mis (feem ncua sawv daws yuav nyob rau hauv ob qho tib si raug raws li zoo raws li nyob rau hauv lub domestic kheej).

Basic yuav tsum mus rau lub twj tso kua mis

twj tso kua mis hom kev lag luam yuav tsum xyuas kom meej tias tag nrho cov uas yuav tsum tau rau lub network uas nws muaj. Feem ntau cov feem ntau nws yog ib tug muaj nuj nqi ntawm "hloov-off" (thaum sau los yog siv kua nyob rau hauv ntim), kom muaj qhov yuav tsum tau siab yog ntau zog los tsis noj tagnrho, teeb meem-dawb lub lag luam nyob rau hauv lub kev hom, thaum muaj xwm ceev shutdown, standby twj tso kua mis kev twb kev txuas. Lub rooj sib tham no yuav tsum tau - tus yuam sij rau nqi-zoo lag luam, cuag cov khoom neej.

Yuav ua li cas yog automation system

Yuav kom tswj tau hom tsim rau automatic twj, uas eliminates lub kev pab tib neeg nyob rau hauv lub khiav hauj lwm hom. Feem ntau, cov kev tswj Circuit Court muab cov kev hloov nyob rau hauv "phau ntawv hom" thaum extraordinary xwm txheej tshwm sim (piv txwv li, tsis ua hauj lwm ntawm tej sensor, ib feem ntawm cov automation). Feem ntau, twj tso kua mis khoom muaj xws li cov nram qab no hais:

1. Siab mus - ib tug membrane-aneroid ntaus ntawv uas thaum muaj ib tug tej yam siab qhib los yog kaw cov hluav taws xob Circuit Court tswj.

2. Cov hluav taws xob hu manometer (CME) nrog lub rooj noj thiab tsau pawg e. hu.

3. Ntab system (ntsia tau rau hauv lub fillable ntim) nrog e-mail. hu.

4. Siab sensors nrog tanzometricheskimi choj kev Process lub kuj mus tam sim no txaus thaum lub siab hloov nyob rau hauv lub system.

5. Neeg kho tshuab los yog hluav taws xob txee ntim kua noj, muab ib lub teeb liab mus rau lub tswj Circuit Court thaum lub teeb ntim.

6. Tus tam sim no zaus converters, hluav taws xob mov. tso lub cev muaj zog.

Hais 1, 2, 4, 5 yog ntsia ncaj qha (lub menyuam pob) nyob rau hauv lub raj dej. Tsis Siv Neeg twj tso kua mis kuj muaj xws li:

• electromagnetic actuators;
• e. switching Circuit Court rau stand-by twj;
• switching pab kiag li lawm kom hloov mus rau "PIB" los yog "LAWM" hom;
• teeb fixtures, taw lub lag luam ntawm lub thaum muaj xwm ceev shutdown, switching rau lub zeem cia, thiab hais txog. thiab lwm yam.;
• tiv thaiv cov khoom el. lub cev muaj zog twj, tswj circuits.

Saum toj no cov khoom mounted nyob rau hauv lub twj tso kua mis tswj xwm nyob rau hauv raws li cov uas yuav tsum tau ntawm SAE (hluav taws xob apparatus kev cai).

hauv paus ntsiab lus ntawm cov lag luam

Yuav ua li cas puas muaj tus tsis siv neeg ntawm lwm yam uas rau cov twj? Feem ntau hom kev rau-off twj tso kua mis. Piv txwv li: ib tug reservoir (tank) ua tus sau nrog kua rau lub yam theem, thaum Ntab system kaw (qhib) lub electromagnetic Actuator kauj Circuit Court uas muaj xws li (disables) twj tso kua mis. Cov tib yam tshwm sim thaum tej lub float mus rau ib tug tej theem. Txoj ntsiab cai tib hauj lwm cov khoom los ntawm lub siab mus, el. ib tug hu rau siab gauge, dej kom tsawg ntim tej txee. Kom muaj lub siab siab txoj kev yog siv hloov cov muab ceev e. tso lub cev muaj zog. Qhov no hom muab cov tam sim no zaus converter, mov el. tso. Zaus converter mas nws txawv nyob ntawm seb nyob rau theem ntawm lub teeb liab los ntawm lub siab sensor. Saab laaj ntawm cov kua circulating nyob rau hauv lub voj kaw (qhov no yog cia li ua cua sov system) yog ensured los ntawm ib tug thaub qab twj tso kua mis, uas yog muaj nyob rau hauv lub chaw ua hauj lwm Circuit Court Failover nyob rau hauv cov ntaub ntawv ntawm tsis ua hauj lwm ntawm lub ntsiab twj tso kua mis.
