The classification of pressure gauges inelectric heat oil hita, kusarudzwa kwezviyero zvekumanikidza uye kuiswa uye kugadzirisa kwemazuva ose emagetsi ekumanikidza.
1 Kurongwa kwezviyero zvekumanikidza
Mageji ekudzvanya anogona kukamurwa kuita zvikamu zvina zvinoenderana nemisimboti yekushandura:
Rudzi rwekutanga imvura column manometer:
Zvinoenderana nemusimboti we hydrostatics, iyo yakayerwa kudzvanywa inoratidzwa nekukwirira kweiyo mvura column. Chimiro chechimiro chakasiyanawo, saka chinogona kukamurwa kuita U-shaped chubhu pressure gauge, single tube pressure gauge zvichingodaro. Iri rudzi rwemanometer rine chimiro chakareruka uye chiri nyore kushandisa, asi kunyatsoita kwayo kuchakanganiswa zvakanyanya nezvinhu zvakaita sekuita kwecapillary tubes, density uye parallax. Nekuti chiyero chekuyera chakatetepa, chinowanzo shandiswa kuyera yakaderera kudzvanywa, kudzvanywa musiyano kana vacuum degree.
Rudzi rwechipiri ndeye elastic manometer:
Iyo inoshandurwa kune yakayerwa kudzvanywa nekutamiswa kwe deformation ye elastic element, senge chitubu chubhu manometer uye mode manometer uye chitubu chubhu manometer.
Rudzi rwechitatu igetsi remagetsi:
Icho chiridzwa chinoshandura kudzvanywa kwakayerwa kuita huwandu hwemagetsi emagetsi uye emagetsi zvinhu (zvakadai sevoltage, ikozvino, frequency, nezvimwewo) yekuyera, seyakasiyana siyana yekumanikidza uye ma sensor sensors.
Rudzi rwechina ipiston pressure gauge:
Inoyerwa nekushandisa musimboti we hydraulic press liquid transfer pressure, uye kuenzanisa huwandu hweiyo yakaenzana silicon kodhi yakawedzerwa kune piston nekuyerwa kudzvanywa. Iyo ine yakakwirira kuyerwa kwechokwadi, idiki se 0.05 intestinal ~ 0? Kukanganisa kwe2%. Asi mutengo wacho unodhura, chimiro chacho chakanyanya kuoma. Kuti utarise mamwe marudzi ekumanikidza mawachi anowanikwa seyakajairwa kuyera kuyera zviridzwa.
Mafuta anopisa sisitimu anoshandiswa mune yakajairika pressure gauge, ine chinhu chakavanzika bourdon chubhu, tafura iri mukati mekufamba kweiyo shanduko nzira, kana kudzvanywa kwagadzirwa, iyo Bourdon chubhu ichave elastic deformation, kufamba kweiyo michina kuenda. shandura iyo elastic deformation kuita inotenderera inotenderera, uye chinongedzo chakabatana nemeshini ichabviswa kuratidza kudzvanywa.
Naizvozvo, iyo geji yekumanikidza inoshandiswa mune inopisa mafuta muvira system ndiyo yechipiri elastic pressure geji.
2 Kusarudzwa kweiyo pressure gauge
Kana kudzvinyirirwa kwebhairi kuri pasi pe 2.5 mi, kururamisa kweyeji yekumanikidza hakusi pasi pe 2.5 level: kushanda kwekushanda kwebhairi kunopfuura 2. SMPa, kururamisa kwechiyero chekumanikidza hakusi pasi pe 1.5 level. ; Kune mabhoilers ane simba rekushanda rinopfuura 14MPa, iko kurongeka kweyeji yekumanikidza kunofanirwa kunge kuri nhanho 1. Iyo dhizaini inoshanda kumanikidza kweiyo inopisa mafuta system ndeye 0.7MPa, saka iko kurongeka kweiyo geji yekumanikidza inoshandiswa haifanirwe kuodzwa mwoyo 2.5 giredhi 2 Nekuti iyo chiyero chekumanikidza gauge chinofanira kunge chiri 1.5 kusvika 3 nguva yakanyanya kudzvinyirira yebhailer, tinotora kukosha kwepakati 2 nguva. Saka kune iyo pressure gauge mari yacho i700.
Iyo yekumanikidza gauge inogadziriswa kune iyo boiler imba, kuitira kuti isangove nyore kuona, asi zvakare nyore kuita nguva dzose yekutsvaira mashandiro uye kushandura nzvimbo yekumanikidza gauge.
3. Kuiswa uye kugadzirisa kwezuva nezuva kwekumanikidza gauge yehuni inopisa yemafuta
(l) Tembiricha yepakati peiyo pressure geji ndeye 40 kusvika 70 ° C, uye hunyoro hwehukama haupfuuri 80%. Kana iyo geji yekumanikidza ikatsauka kubva kune yakajairika tembiricha yekushandisa, tembiricha yekuwedzera kukanganisa inofanira kuverengerwa.
(2) Iyo geji yekumanikidza inofanirwa kuve yakatwasuka, uye kuyedza kuchengetedza nhanho imwe chete neyeyero poindi, sekuti musiyano wakanyanya kukwirira mukukanganisa kwekuwedzera kunokonzerwa nekoramu yemvura, kuyerwa kwegasi hakugone kutariswa. Paunenge uchiisa, vhara kuputika-kuvhura kuvhura kuseri kwekesi kuitira kuti usakanganise kuputika-uchapupu hwekuita.
(3) Chiyero chekuyera chekushandiswa kwechinyakare chekumanikidza gauge: kwete kupfuura 3/4 yekuyera yekumusoro muganhu pasi pe static pressure, uye kwete kupfuura 2/3 yekuyera yepamusoro muganhu pasi pekuchinja. Mumakesi maviri ari pamusoro pekumanikidza, chiyero chidiki cheiyo yakakura yekumanikidza geji haifanirwe kunge yakaderera pane 1/3 yemuganho wepasi, uye iyo vacuum chikamu chese chinoshandiswa pakuyera vacuum.
(4) Paunenge uchishandisa, kana iyo yekumanikidza geji pointer ikatadza kana zvikamu zvemukati zvakasununguka uye zvisingashande zvakajairwa, zvinofanirwa kugadziriswa, kana kubata mugadziri kuti agadzirise.
(5) Chiridzwa chinofanira kudzivirira kuzunguzika uye kubonderana kudzivirira kukuvara.
Kana iwe uine chero mibvunzo nezve electric thermal oiri choto, ndapotataura nesu.
