Fais fab proportional valve-xa mus raws li proportional valve.Nws cov yam ntxwv yog tias qhov tso zis ntau npaum li cas hloov nrog cov khoom nkag.Muaj qee qhov kev sib raug zoo ntawm cov zis thiab cov tswv yim, yog li nws yog hu ua hluav taws xob proportional valve.

Lub valve proportional yog tsim los ntawm ib qho hluav taws xob-mechanical converter thiab pneumatic amplifier, thiab yog lub kaw lus kaw.Lub kaw lus tsis tu ncua kuaj pom cov zis (siab) ntawm qhov tso zis kawg thiab pub nws rov qab mus rau qhov kev tawm tswv yim kawg ntawm qhov system rau kev sib piv nrog cov tswv yim (yuav tsum muaj nqis).Thaum tus nqi tiag tiag ntawm cov zis (tus nqi siab) deviates los ntawm cov tswv yim (tus nqi xav tau), lub kaw lus cia li kho qhov tso zis los hloov cov kev taw qhia ze rau cov tswv yim, thiaj li xyuas kom meej tias cov zis ruaj khov nyob rau hauv tus nqi siab xav tau. los ntawm cov tswv yim.Tswj kom muaj kev sib raug zoo ntawm cov zis thiab cov khoom siv.

Nta:

Cov zis siab hloov pauv nrog cov teeb liab tawm tswv yim, thiab muaj qee yam proportional

kev sib raug zoo ntawm cov zis siab thiab lub teeb liab input.

Nrog stepless voltage tswj muaj peev xwm.

Nrog lub peev xwm ntawm cov chaw taws teeb tswj thiab kev tswj hwm kev tswj hwm: tus nqi ntawm cov proportional valve yog teem los ntawm kev sib txuas lus, lub teeb liab kis tau tus mob ntawm cov chaw taws teeb tswj yog ruaj khov dua, thiab kev tswj qhov deb kuj tseem yuav txuas ntxiv.Nws tuaj yeem pom tau los ntawm PC, ib qho nti microcomputer, PLC thiab lwm yam khoom siv.

Nco tseg:

1. Ua ntej qhov hluav taws xob proportional valve, lub tshuab lim cua thiab cov roj pos huab cais nrog kev pom tseeb ntawm 5μm lossis tsawg dua yuav tsum tau teeb tsa.Muab cov huab cua huv thiab qhuav compressed rau lub proportional valve thiaj li ua tiav cov yam ntxwv ntawm cov hluav taws xob proportional valve.

2. Ua ntej kev teeb tsa, cov kav dej yuav tsum tau ntxuav.

3. Tsis muaj lubricator yuav tsum tau ntsia rau pem hauv ntej kawg ntawm lub proportional valve.

4. Lub proportional valve txiav tawm lub hwj chim mov nyob rau hauv lub xeev pressurized, thiab lub siab ntawm lub qhov hluav taws xob sab yuav tsum tau ib ntus tswj, uas yog tsis guaranteed.Yog tias koj xav tau qhov cua, tua lub hwj chim tom qab txo qhov teeb tsa siab, thiab siv qhov seem siab nyem valve kom tso tawm.

5. Nyob rau hauv lub xeev tswj ntawm proportional valve, lub siab nyob rau hauv lub qhov hluav taws xob sab yuav tsum tau khaws cia ib zaug vim lub hwj chim tsis ua hauj lwm los yog lwm yam tsis muaj zog.Tsis tas li ntawd, thaum lub qhov hluav taws xob sab yog qhib rau cov cua, lub siab tseem yuav poob mus rau atmospheric siab.

Tom qab lub proportional valve yog energized, yog hais tias lub mov siab raug txiav tawm, lub solenoid valve tseem yuav ua hauj lwm, uas yuav tsim ib tug popping suab thiab txo nws lub neej.Yog li ntawd, cov khoom siv hluav taws xob yuav tsum raug txiav tawm thaum lub tshuab hluav taws xob raug txiav tawm, txwv tsis pub lub valve proportional yuav nkag mus rau "lub xeev pw tsaug zog".

6. Cov khoom lag luam valve tau raug hloov kho ua ntej tawm hauv lub Hoobkas, thov tsis txhob disassemble nws kom tsis txhob ua haujlwm tsis zoo.

7. Thaum lub valve proportional tsis siv cov kev soj ntsuam cov zis (hloov cov zis), cov kev soj ntsuam cov zis xaim (dub hlau) tsis tuaj yeem tiv tauj nrog lwm cov xov hlau kom tsis txhob ua haujlwm tsis zoo.Kev siv cov khoom siv inductive (solenoid li qub, relays, thiab lwm yam) yuav tsum muaj kev ntsuas kev nqus dhau-voltage.

8. Tsis txhob ua haujlwm tsis zoo los ntawm hluav taws xob nrov.Cov khoom no thiab nws cov hlua yuav tsum nyob deb ntawm lub cev muaj zog thiab cov kab hluav taws xob kom tsis txhob muaj qhov cuam tshuam ntawm lub suab nrov.

9. Thaum cov zis sab nraud muaj qhov ntim loj thiab cov dej ntws tawm yog siv raws li lub hom phiaj, lub suab nrov nrov thaum lub sijhawm dhau mus, thiab qhov chaw nres nkoj tso tawm yuav tsum tau nruab nrog lub suab ntsiag to.

10. Thaum tus nqi xav tau tsawg dua 0.1V, nws raug suav tias yog 0V.Hauv qhov xwm txheej no, qhov tso zis siab yog teem rau 0 Bar los ntawm kev ua kom lub qhov tso pa tawm thiab cov pa roj hauv qhov sib npaug ntawm lub valve yog sab laug.

11. Ua ntej txiav tawm lub hwj chim ntawm lub proportional valve, thov nco ntsoov txiav tawm tus nqi voltage (tsawg dua 0.1V), ces txiav tawm qhov cua qhov siab, thiab thaum kawg txiav tawm lub hwj huam mov ntawm proportional valve.

12. Gas qhov yuav tsum tau muaj: lub input siab yuav tsum siab tshaj qhov tso zis siab los ntawm ntau tshaj 0.1MP, thiab ua tau raws li tag nrho cov roj noj, uas yog, cov input flow yog ntau tshaj qhov tso zis ntws.
