Kutarisisa kusarudzwa kwakaringana kwemavharuvhu mukuvaka pombi masisitimu - Nhungamiro yekusarudzwa kweakakosha mavharuvhu chinzvimbo munzvimbo yekutonga.

Kucherechedza kusarudzwa kwakarurama kwemavharuvhu mukuvaka pombi masisitimu - Nhungamiro yekusarudzwa kweakakosha mavharuvhu chinzvimbo munzvimbo yekudzora Mukuvaka pombi, mavharuvhu anoita basa rekudzora mvura. Nekuda kwechimiro chakasiyana uye zvinhu, saka mavharuvhu anogadzirwa haana kufanana. Kuti uve nechokwadi chekuti hurongwa hwepombi hunogona kubudirira zvakanyanya, mutengo wakaderera uye hupenyu hurefu hwebasa, kusarudzwa kwakakodzera kwemavharuvhu kwakakosha. Ivhavha ine mabasa mana makuru: kutanga uye kumisa kuyerera kwenhau; Rongedza kuyerera kwepakati; Inodzivirira kudzoka shure kana kuti reflux uye inogadzirisa kana kuderedza kudzvinyirira kwemvura. Sarudzo yekuvaka pombi system inogona kutariswa zvinoenderana nekushisa, yepakati mhando, tembiricha uye zvimwe zvinhu. , semuenzaniso, munzvimbo yakakwirira-inokwira moto hydrant valve control valve inofanira kushandiswa chiratidzo, izvi zvine chokuita kana iyo moto hydrant system ndiyo kiyi yekushandisa zvine musoro, kana mavharuvhu emagetsi emagetsi emagetsi akaiswa chiratidzo chevhavha, uye vharafu yakavhurika kuti iratidze pakati pekutonga kwemoto, kuitira kuti ifambise kuongororwa kwekutungamira, kunyangwe mutengo wakawedzera, zvisinei, Chiyero chekudyara kune iyo yakazara hydrant system ichiri diki, uye inogona kuita kuchengetedzwa kwese kwe. iyo hydrant system, iyo yakakodzera mari. Rudzi rwevharuvhu INOSHANDISA mune yekuvaka pombi system inofanirwa kusarudzwa zvinoenderana nehunhu hwechivako. Kana iyo valve inoshandiswa isingakodzeri maitiro ekugadzirwa kwechivako, huwandu hwenjodzi dzinogona kuitika dzinogara dzichimuka. Kusarudzwa kwevhavha positioner kuchakanganisa zvakananga kushanda uye kunaka kwekugadzirisa valve uye hurongwa hwekugadzirisa. Saka nzira yekusarudza iyo valve positioner nenzira kwayo uye zvine musoro inonyanya kukosha munharaunda yekutonga. Mazwi akakosha: gwara rekusarudza vharafu mune akawanda ekudzora mashandisirwo, vharafu chinzvimbo ndechimwe chezvinhu zvakakosha zvekushandisa. Kune imwe application, kana iwe uchida kusarudza yakakodzera (kana yakanaka) valve locator, iwe unofanirwa kufunga nezve zvinotevera zvinhu: 1) Ko nzvimbo yevhavha inogona "kutsemuka-kutsemuka"? Zviri nyore uye zviri nyore kushandisa "kupatsanura"? Kuve ne "kutsemuka" basa kunoreva kuti vharafu inomira inopindura chete kune akasiyana ekuisa masaini (semuenzaniso, 4 kusvika 12mA kana 0.02 kusvika 0.06MPaG). Naizvozvo, kana iwe uchikwanisa "kupatsanura", iwe unogona maererano nezvinodiwa chaizvo, chiratidzo chimwe chete chekuisa kuti uwane kutonga kwemavharuvhu maviri kana anopfuura ekudzora. 2) Kugadziriswa kwe zero point uye renji iri nyore uye nyore? Zvinoita here kugadzirisa zero uye renji pasina kuvhura chivharo? Nekudaro, zvakakosha kuti uzive kuti dzimwe nguva kurongedza kwakadai kunoda kurambidzwa kuitira kudzivirira kuita zvisirizvo (kana zvisiri pamutemo). 3) Chii chinonzi kugadzikana kwe zero uye renji? Kana ZERO UYE RANGE YAKATAURWA KUDRIFT NEKUCHINJWA KWETEMPERATURE, VIBRATION, TIME, KANA INPUT PRESSURE, VALVE POSITIONER INODA KUDZORERWA KAZHINJI KUTI tive nechokwadi chekufamba kwakaringana kweRegulator. 4) Ko chibatiso chevharuvhu chakarurama zvakadii? Zvakanaka, kune chiratidzo chekuisa, iyo Trim Zvikamu zvevhavha (Trim Parts, kusanganisira spool, stem, chigaro chevharuvhu, nezvimwewo) nguva yega yega inofanirwa kuiswa munzvimbo inodiwa, zvisinei negwara rekufamba kana kudzora vharafu nenzira. mutoro wakawanda wenhengo dzemukati. 5) Chii chinodiwa chemhando yemhepo yevhavha chinzvimbo? Sezvo chete nhamba shoma shoma yezvikwata zvekupa mhepo zvinogona kupiwa kuti zvienderane neISA mitemo (yemhando yemhando yemhepo yezviridzwa: ISA STANDARD F7.3) YEMHEPO, ZVINO, YEMHEPO-MOBILIZED OR ELECTRIC-GAS (VALVE) POSITIONERS, KANA VACHIDA. NDEKUKATAMIRIRA ZVINHU ZVINOGONA-ZVENYIKA, VANOFANIRA KUGONA KUTARISANA NECHIMWE CHIKAMU CHEGURUVA, UFURO NE MAFUTA. 6) Ko iyo calibration ye zero uye renji inokanganisa mumwe nemumwe kana ivo vakazvimiririra? Kana dzikabata mumwe nemumwe, mazero uye mitsara inotora nguva yakawanda kugadzirisa, nekuti tuner inofanirwa kudzokorodza kugadzirisa aya maviri ma paramita kuti zvishoma nezvishoma asvike pakurongeka chaiko. 7) Iyo valve positioner yakashongedzerwa ne "Bypass" iyo inobvumira iyo yekuisa chiratidzo kuti iite zvakananga pane regulator? Iyi "bypass" dzimwe nguva inogona kurerutsa kana kusiya iyo calibration yeActuator Settings, senge: Iyo "Benchset kuseta" uye "Seat Load kuseta" kweiyo actuator - izvi zvinodaro nekuti muzviitiko zvakawanda, iyo aerodynamic inobuda chiratidzo chevamwe pneumatic regulators. inofananidzwa ne "seat set" ye actuator chaizvo kuitira kuti pasave nekumwe kuseta kunodiwa (chaizvoizvo, mune iyi nyaya, Valve positioners inogona kubviswa zvachose. Zvechokwadi, kana yakasarudzwa, ipapo valve positioner inogonawo kushandiswa "bypass" iyo pneumatic inobuda chiratidzo cheiyo pneumatic regulator zvakananga pane regulator). Mukuwedzerwa, ne "bypass" dzimwe nguva inogonawo kubvumira kugadziriswa kuduku kana kuchengetedza kwevhavha inomira pamhepo (kureva, kushandiswa kwevhavha positioner "bypass" kuitira kuti mutongi arambe achichengetedza basa rakajairwa, pasina kumanikidza mutongi kunze kwenyika. ) 8) Kana basa revhavha positioner rinokurumidza? Kuyerera kwemhepo Kukura kwemhepo (iyo valve locator inogara ichienzanisa chiratidzo chekupinza uye chiyero chevharuvhu uye inogadzirisa kuburitsa kwayo zvichienderana nekusiyana. Kana iyo valve positioner inopindura nekukurumidza kune iyi kutsauka, ipapo kuwedzera kwemhepo kuyerera pane imwe unit nguva), iyo inokurumidza kugadzirisa. system inopindura kuSetpoint uye misiyano yekuremedza - zvinoreva kushoma system kukanganisa (lag) uye nani kutonga mhando. 9) Iyo Frequency maitiro eiyo valve positioner (kana frequency Response, Frequency Response -- G (jω), ndeipi mhinduro yakatsiga yegadziriro kune sinusoidal input? iyo yakakwirira senitivity kufrequency response), zviri nani mashandiro ekutonga, zvisinei, zvinofanirwa kucherechedzwa kuti ma frequency maitiro anofanirwa kutariswa neConsistent Test Methods pane nzira dzedzidziso, uye chinomira chevhavha uye actuator zvinofanirwa kutariswa pamwe chete pakuongorora. frequency maitiro. Semuyenzaniso, mamwe mavharuvhu anomira ane hombe yakayerwa yemhepo yekumanikidza ye501b/in (kureva 50psi, lpsi =0.07kgf/cm ≈ 6.865kpa), chinomira chevharuvhu chinova chinomanikidza kuburitsa kubuda kweactuator kana actuator yakatemerwa kuti ishande. pakumanikidzwa kwakakwirira kudarika 501b/in. 11) Kana iyo yekudzora vharafu nevhavha chinzvimbo zvaunganidzwa uye zvakabatanidzwa, ko nezve yavo Positioning Resolution? Izvi zvine mhedzisiro yakajeka pahutongi hwehutongi hwehurongwa hwekutonga, nekuti iyo yakakwira kugadziriswa, iyo inoswedera pedyo nekumisikidzwa kwevharuvhu yekudzora ndeyekukosha kwakaringana, uye kushanduka kwekuchinja kunokonzerwa neOvershooting yevhavha inotonga inogona kudzorwa, kuitira kudzikamisa shanduko dze periodic dzehuwandu hwakadzorwa. 12) Kana iyo yakanaka uye yakaipa kutendeuka kwevhavha positioner inogoneka? Kuchinja kuri nyore here? Dzimwe nguva chimiro ichi chinodiwa. Semuenzaniso, KUTI uchinje "SIGNAL INCREASe-VALVE PEDYO" modhi kuti "SIGNAL INCREASE-VALVE OPEN" MODE, UNOGONA KUSHANDISA VALVE POSItioner's positive AND NEGATIVE CONVERSION function. 13) Zvakaoma sei kushanda kwemukati uye kuchengetedza kwevhavha positioner? Sezvo isu tese tinoziva, iyo yakawanda zvikamu, iyo yakanyanya kuomarara chimiro chemukati chekushanda, iyo yakawanda yekudzidziswa kwekugadzirisa (kugadzirisa) vashandi, uye zvimwe zvakasara zvikamu mustock. 14) Chii chinonzi Steady-state Air Consumption yevhavha chinzvimbo? Kune kumwe kumisikidzwa kwechirimwa, iyi parameter yakakosha uye inogona kuve inomisa chinhu. 15) Ehe, zvimwe zvinhu zvinofanirwa kutariswa pakuongorora nekusarudza mavharuvhu chinzvimbo. Semuenzaniso, Feedback Linkage yevharuvhu inomira inofanira kuratidza nzvimbo ye spool; Uye zvakare, iyo vharafu yekumisikidza inofanirwa kuve yakasimba uye yakasimba, ine kuchengetedzwa kwezvakatipoteredza uye corrosion kuramba, uye nyore kuisa nekubatanidza.
