Kev teeb tsa qhov tsis tseem ceeb ntawm lub tshuab hluav taws xob valve
Hluav taws xob actuator valve
Lub tshuab hluav taws xob valve yog ib qho khoom siv tsav tsheb tsis tseem ceeb kom paub txog kev tswj cov chaw taws teeb, kev tswj tsis siv neeg thiab cov chaw taws teeb tswj ntawm lub valve. Nws cov txheej txheem txav tuaj yeem tswj tau los ntawm stroke, torque lossis axial thrust. Vim hais tias lub valve hluav taws xob cov cuab yeej ua haujlwm cov yam ntxwv thiab kev siv yog nyob ntawm hom valve, cov cuab yeej ua haujlwm tshwj xeeb thiab lub valve txoj haujlwm hauv cov kav dej lossis cov khoom siv.
Cov cuab yeej hluav taws xob feem ntau muaj cov hauv qab no:
** lub cev muaj zog yog qhov muaj zog tshaj qhov muaj peev xwm, pib lub zog loj, lub sijhawm me me ntawm inertia, lub sijhawm luv luv, ua haujlwm tsis sib xws.
Kev txo qis mechanism rau txo qhov tso zis ceev ntawm lub cev muaj zog.
Stroke tswj mechanism los kho thiab raug tswj qhov qhib thiab kaw txoj haujlwm ntawm lub valve.
Torque limiting mechanism rau kho torque (los yog thrust) rau tus nqi predetermined.
Phau ntawv thiab hluav taws xob hloov mechanism, interlocking mechanism rau phau ntawv los yog hluav taws xob ua haujlwm.
Qhov taw qhia qhib qhia qhov chaw ntawm lub valve thaum qhib thiab kaw.
Ua ntej, xaiv qhov hluav taws xob actuator raws li hom valve
1. Lub kaum sab xis stroke hluav taws xob actuator (Lub kaum ntse ntse 360 ​​degrees) yog tsim rau npauj npaim valve, pob valve, ntsaws valve, thiab lwm yam.
Kev sib hloov ntawm cov zis ncej ntawm lub tshuab hluav taws xob yog tsawg tshaj li ib lub lim tiam, uas yog, tsawg dua 360 degrees, feem ntau yog 90 degrees kom paub txog lub valve qhib thiab kaw cov txheej txheem tswj. Hom hluav taws xob actuator no tau muab faib ua hom kev sib txuas ncaj qha thiab lub hauv paus crank hom raws li qhov sib txawv installation interface hom.
A) Kev sib txuas ncaj qha: yog hais txog daim ntawv ntawm kev sib txuas ncaj qha ntawm cov khoom tso tawm ntawm lub tshuab hluav taws xob thiab lub valve qia.
B) Base crank hom: yog hais txog daim ntawv uas cov zis ncej txuas nrog lub valve qia los ntawm crank.
2. Multi-rotary hluav taws xob actuator (Lub kaum ntse ntse 360 ​​degrees) yog tsim rau lub rooj vag li qub, lub ntiaj teb li qub, thiab lwm yam.
Kev sib hloov ntawm cov zis ncej ntawm lub tshuab hluav taws xob yog ntau dua ib lub lim tiam, uas yog, nws yog ntau dua 360 degrees. Nws feem ntau xav tau ntau tshaj ib lub voj voog kom paub qhov qhib thiab kaw txheej txheem tswj ntawm lub valve.
3. Ncaj nraim (txoj kev ncaj nraim) yog tsim rau tib lub rooj tswj valve, ob lub rooj tswj valve, thiab lwm yam.
Cov lus tsa suab ntawm cov zis ncej ntawm hluav taws xob actuator yog linear motion, tsis tig.
Ob, raws li cov txheej txheem ntau lawm tswj yuav tsum tau txiav txim siab hom kev tswj ntawm hluav taws xob actuator
1. Hloov hom (qhib voj tswj)
Hloov hluav taws xob actuators feem ntau paub txog kev tswj lub valve ntawm lossis tawm. Lub valve yog nyob rau hauv ib qho chaw qhib tag nrho los yog nyob rau hauv qhov chaw kaw tag nrho. Hom valve no tsis tas yuav raug tswj xyuas qhov nruab nrab ntws.
Nws yog tshwj xeeb tshaj yog tsim nyog hais tias kev hloov hluav taws xob actuators kuj tuaj yeem muab faib ua cov qauv sib cais thiab kev sib xyaw ua ke vim muaj cov qauv sib txawv. Qhov no yuav tsum tau piav qhia thaum xaiv hom, txwv tsis pub nws feem ntau tshwm sim hauv kev teeb tsa thiab kev tswj hwm qhov system *** thiab lwm yam tsis sib xws.
A) Split structure (feem ntau hu ua hom hom): lub chaw tswj tau sib cais los ntawm cov hluav taws xob actuator. Cov hluav taws xob actuator tsis tuaj yeem tswj lub valve ntawm nws tus kheej, tab sis yuav tsum tau tswj los ntawm lub chaw tswj xyuas sab nraud. Feem ntau, cov tswj sab nraud lossis cov txee tswj yog siv los txhawb nqa.
Qhov tsis zoo ntawm cov qauv no yog tias nws tsis yooj yim rau kev teeb tsa tag nrho ntawm lub kaw lus, nce cov kab hluav taws xob thiab kev teeb tsa tus nqi, thiab ua rau tsis ua haujlwm, thaum qhov tsis ua haujlwm tshwm sim, nws tsis yooj yim rau kev kuaj mob thiab kev saib xyuas, kev siv nyiaj tsis zoo. .
B) Cov qauv sib xyaw ua ke (feem ntau hu ua ib hom): chav tswj thiab lub tshuab hluav taws xob tau ntim tag nrho, uas tuaj yeem ua haujlwm hauv zos yam tsis muaj kev tswj hwm sab nraud, thiab tuaj yeem ua haujlwm nyob deb tsuas yog los ntawm kev tshaj tawm cov ntaub ntawv tswj xyuas.
Qhov zoo ntawm cov qauv no yog qhov yooj yim ntawm kev teeb tsa tag nrho, txo cov nqi xaim thiab kev teeb tsa, kev kuaj mob yooj yim thiab daws teeb meem. Txawm li cas los xij, cov khoom lag luam sib xyaw ua ke kuj muaj ntau yam tsis zoo, yog li cov khoom siv hluav taws xob ntse yog tsim.
2. Adjustable hom (kaw voj tswj)
Lub regulating hluav taws xob actuator tsis tsuas yog muaj kev ua haujlwm ntawm kev hloov hom kev sib xyaw ua ke, tab sis kuj tuaj yeem tswj tau lub valve kom raug thiab kho qhov nruab nrab ntws.
A) Tswj teeb liab hom (tam sim no, voltage)
Kev tswj cov teeb liab ntawm cov tswj hluav taws xob actuator feem ntau muaj cov teeb liab tam sim no (4 ~ 20mA, 0 ~ 10mA) lossis voltage teeb liab (0 ~ 5V, 1 ~ 5V). Hom thiab qhov tsis sib xws ntawm cov teeb liab tswj yuav tsum meej thaum xaiv hom.
B) Daim ntawv ua haujlwm (hluav taws xob ntawm hom, hluav taws xob tawm hom)
Hom kev ua haujlwm ntawm kev tswj hluav taws xob hluav taws xob feem ntau yog hluav taws xob qhib hom (kev tswj hwm ntawm 4 ~ 20mA ua piv txwv, hom hluav taws xob qhib yog hais txog qhov sib thooj 4mA teeb liab yog lub valve kaw, sib xws 20mA valve qhib), thiab lwm yam yog hom hluav taws xob kaw (kev tswj hwm ntawm 4-20MA ua piv txwv, hom hluav taws xob qhib yog hais txog qhov sib thooj 4mA teeb liab yog lub valve qhib, qhov sib thooj 20mA valve kaw). Hnav-resistant electrode
C) poob ntawm kev tiv thaiv teeb liab
Poob kev tiv thaiv teeb liab hais txog qhov poob ntawm kev tswj cov teeb liab vim kab tsis ua haujlwm, hluav taws xob actuator yuav tswj lub valve qhib thiab ze rau qhov teeb tsa kev tiv thaiv tus nqi, qhov kev tiv thaiv tus nqi yog qhib tag nrho, kaw tag nrho, khaws cia nyob rau hauv peb qhov xwm txheej.
Peb, raws li kev siv ib puag ncig thiab tawg-pov thawj qib kev faib tawm ntawm cov khoom siv hluav taws xob
Raws li cov kev xav tau ntawm kev siv ib puag ncig thiab qib tawg, cov khoom siv hluav taws xob ntawm lub valve tuaj yeem muab faib ua hom zoo tib yam, hom sab nraum zoov, hom flameproof, hom flameproof sab nraum zoov.
Txiav txim siab qhov tso zis torque ntawm hluav taws xob actuator raws li lub zog xav tau los ntawm lub valve
Valve qhib thiab kaw qhov yuav tsum tau torque txiav txim siab qhov tso zis torque ntawm hluav taws xob actuator xaiv yuav ua li cas, feem ntau yog muab tso rau pem hauv ntej los ntawm tus neeg siv lossis los ntawm cov chaw tsim khoom valve, raws li cov chaw tsim khoom actuator tsuas yog lub luag haujlwm rau cov zis torque ntawm actuators, lub valve qhib thiab kaw. qhov yuav tsum tau torque yog txiav txim los ntawm lub valve txoj kab uas hla loj thiab ua hauj lwm siab, tab sis vim hais tias ntawm lub valve chaw tsim tshuaj paus ua precision, cov txheej txheem los ua ke, Yog li ntawd, lub torque yuav tsum tau los ntawm tib specifications li qub uas tsim los ntawm txawv manufacturers kuj txawv, txawm tias nws yog. tib lub ntsiab lus ntawm cov li qub uas tsim los ntawm tib lub chaw tsim khoom valve. Thaum xaiv tus actuator, qhov kev xaiv torque tsawg dhau los ua rau lub cev qhib thiab kaw lub valve, yog li lub tshuab hluav taws xob yuav tsum xaiv qhov tsim nyog ntau yam ntawm torque.
Plaub, qhov kev xaiv raug ntawm valve hluav taws xob ntaus ntawv hauv paus:
Kev khiav hauj lwm torque: kev khiav hauj lwm torque yog lub ntsiab parameter ntawm lub valve hluav taws xob ntaus ntawv, qhov tso zis torque ntawm lub tshuab hluav taws xob yuav tsum yog 1.2 ~ 1.5 npaug ntawm lub siab tshaj plaws torque ntawm lub valve ua haujlwm.
Kev khiav hauj lwm thrust: muaj ob lub ntsiab qauv ntawm lub valve hluav taws xob ntaus ntawv: ib tug tsis yog nruab nrog thrust phaj, ncaj qha tso zis torque; Lwm qhov yog nruab nrog thrust disc, qhov tso zis torque los ntawm thrust disc qia txiv ntoo hloov mus rau hauv cov zis thrust.
