Cov khoom siv hluav taws xob hluav taws xob hluav taws xob tuaj yeem hloov kho
Qhov hluav taws xob
Lub zog hluav taws xob ntawm lub tshuab hluav taws xob feem ntau muaj ntau qhov hluav taws xob xws li 24V, 48V, 110V, 220V, 230V, 380V, 415V thiab lwm yam. Tsis tas li ntawd, qhov voltage ntawm domestic hluav taws xob actuators thiab txawv teb chaws hluav taws xob actuators yog qee zaum txawv, feem ntau yog nyob ntawm lub ntsiab voltage ntawm lub teb chaws thiab cov khoom siv hluav taws xob tshwj xeeb ntawm qhov chaw. Lub ntsiab voltages ntawm domestic hluav taws xob actuators yog 220V thiab 380V. 200V voltage feem ntau muaj qis zog, thiab 380V voltage feem ntau muaj lub zog siab. Qhov ceev ntawm 380V lub cev muaj zog kuj qeeb, tab sis lub zog ntawm 380V lub cev muaj zog yog qhov loj, thiab cov zis tawm zog loj dua.
1. Qhov txawv: 380V motors feem ntau yog peb-theem motors, thaum 220V motors feem ntau yog ib-theem motors.
2. Peb-theem lub cev muaj zog txhais tau hais tias thaum peb-theem stator windings ntawm lub cev muaj zog (txhua lub sijhawm sib txawv ntawm 120 degrees) txuas nrog peb-theem alternating tam sim no, lub rotating magnetic teb yuav raug generated, thiab rotating magnetic teb. teb yuav txiav lub rotor winding, yog li tsim nyob rau hauv lub rotor winding Induced tam sim no (rotor winding yog kaw txoj kev).
3. Ib-theem lub cev muaj zog feem ntau yog hais txog lub zog qis ib-theem asynchronous lub cev muaj zog los ntawm ib theem AC fais fab mov (AC220V). Hom lub cev muaj zog no feem ntau muaj ob-theem windings ntawm lub stator thiab lub rotor yog hom squirrel-cage. Kev faib tawm ntawm ob-theem windings ntawm lub stator thiab cov khoom siv hluav taws xob sib txawv tuaj yeem tsim cov yam ntxwv sib txawv pib thiab khiav.
Dab tsi yog qhov kev tswj hluav taws xob thiab kev ua haujlwm voltage ntawm hluav taws xob actuator?
Kev ua haujlwm voltage yog hais txog qhov hluav taws xob ntawm lub tshuab hluav taws xob, thiab kev tswj qhov hluav taws xob yog hais txog kev siv hluav taws xob ntawm cov khoom siv pabcuam (relays, contactors, thiab lwm yam) uas tswj kev ua haujlwm ntawm cov hluav taws xob actuator, tseem hu ua cov kab hluav taws xob theem nrab. Kev tswj qhov hluav taws xob ntawm lub tshuab hluav taws xob yog hais txog qhov hluav taws xob uas lub kaw lus tswj tau xa cov lus txib mus rau lub tshuab hluav taws xob, xws li cov chaw taws teeb qhib thiab kaw cov lus txib, thiab lwm yam. hluav taws xob actuator.
Dab tsi yog qhov txawv ntawm 24V AC thiab 24V DC?
1. Kev ruaj ntseg sib txawv: qhov loj thiab kev taw qhia ntawm 24V alternating tam sim no hloov nrog lub sij hawm; Kev taw qhia ntawm 24V ncaj qha tam sim no yuav tsis hloov nrog lub sijhawm, tsis muaj qhov hloov pauv raws sijhawm, thiab nws kuj tseem ruaj khov.
2. Qhov poob yog qhov sib txawv: Kev sib kis ntawm 24V AC yog me me, haum rau kev sib kis mus ntev; Kev sib kis ntawm 24V DC yog qhov loj, yog li nws tsis haum rau kev sib kis mus ntev;
3. Qhov loj ntawm qhov poob qis yog qhov sib txawv: tus nqi ntawm qhov poob qis thaum lub sij hawm kis tau tus mob ntawm 24V AC lub zog yog loj, thiab cov yam ntxwv ntawm kev yooj yim kauj ruam-down tsuas yog tsim nyog rau realizing high-voltage fais fab kis.
Qhov txawv ntawm active hluav taws xob actuator thiab passive
Cov khoom siv hluav taws xob feem ntau muab faib ua peb hom: tus qauv hluav taws xob lub taub hau, lub taub hau hluav taws xob passive, thiab cov khoom siv hluav taws xob ntse. Tus qauv valve hluav taws xob ntaus ntawv yog nquag, thiab qhov hloov ntawm lub valve yog ncaj qha tswj los ntawm 220V hloov. Lub tshuab hluav taws xob passive yog nyob rau hauv 220V, thiab qhov hloov ntawm lub valve yog tswj los ntawm lub tswv yim hloov teeb liab. Cov cuab yeej ntse hluav taws xob yog DC12V, uas yog tswj los ntawm ib lub microcomputer ib leeg, thiab muaj cov tswv yim tawm tswv yim thiab tawm tswv yim tawm tswv yim. Qhov sib txawv ntawm cov teeb liab nquag thiab cov teeb liab passive: Piv txwv li, siv qhov hloov S los tswj lub kauj ntawm 12VDC relay K, thiab cov kev sib cuag ntawm K raug cim nrog 1 thiab 2 ntawm ob qho kawg.
Yog li:
1. Lub sab sauv kawg ntawm kev hloov S yog txuas nrog 12VDC, thiab cov zis "cim" los ntawm qis kawg yog "lub teeb liab";
2. Lub relay K ua, thiab 1 thiab 2 kev sib cuag yog muab raws li "cov teeb liab" rau lwm yam khoom siv, uas yog, lub teeb liab tso tawm ntawm "passive signal" (tsis hais txog lub hwj chim mov) qhov chaw tuaj yeem xa ncaj qha cov lus tawm tswv yim. rau DCS. Lub teeb liab tso zis ntawm passive hluav taws xob actuator xav tau DCS los muab qhov hluav taws xob ua ntej nws tuaj yeem siv tau.
