Maitiro ekuyedza Pressure switch (Matanho matanhatu)
Zviri mukati
Pakupera kwechinyorwa chino, iwe unozoziva nzira yekuyedza nyore uye zvinobudirira yekumanikidza switch.
Ese anodzvanywa switch anofanirwa kuve neakafa zone buri rekuita kwakanyanya. Iyo yakafa bhendi ndiyo mutsauko pakati pekumanikidza kusimuka uye kudonha seti mapoinzi, ayo anogona kuwanikwa nyore. Iyo yakafa zone inoisa chikumbaridzo chekugadzira uye kutyora kubatanidza magetsi mumudziyo. Semunhu anoshanda, ini kazhinji ndinofanira kutarisa uye kugadzirisa nyaya dzekufa pamidziyo yakaita seHVAC firiji. Kuziva chikumbaridzo chekufa kwechibatiso chako chekumanikidza ndicho kiyi yekunzwisisa uye kugadzirisa yako yekumanikidza switch uye zvimwe zvese zvinoshandiswa zvinodzora.
Kazhinji, maitiro ekutarisa kana yako yekumanikidza switch ine yakafa zone chikumbaridzo iri nyore.
- Bvisa chibatiso chekumanikidza kubva pachigadzirwa chainoronga.
- Gadzirisa iyo yekumanikidza switch neDMM calibrator kana chero imwe yakanaka calibrator.
- Batanidza chinodzvanya chinja kune chinomanikidza sosi sepombi yeruoko yakanamirwa kune yekumanikidza geji.
- Wedzera kudzvanya kusvika kudzvanya chinja kubva pakuvhurika kuenda kuvharwa.
- Nyora kukosha kwekuwedzera kwekumanikidzwa kwakaiswa
- Zvishoma nezvishoma dzikisa kudzvanywa kusvika iyo yekumanikidza switch yachinja kubva kuvhurika kuenda kuvharwa.
- Rekodha kudonha kwekumanikidza
- Verenga mutsauko uripo pakati pekukwira nekudonha kudzvanywa mune akanakisa pints
Ndichanyatsoongorora izvi.
Kutarisa chinja chekumanikidza
Kuongorora kudzvanywa switch haisi yakaoma maitiro. Iyi inotevera maitiro ichakubatsira iwe kunyatso kuyedza iyo yekumanikidza switch yakafabhendi chikumbaridzo.
Seta mudziyo wako
Kutanga, iwe unofanirwa kuseta mudziyo wako; matanho anotevera achabatsira:
Danho 1: Bvisa iyo yekumanikidza switch
Bvisa dhizaini yekudzvanya kubva pachishandiso chainodzora nekungwarira uye zvishoma nezvishoma. Midziyo inodzorwa nekudzvanyirira switch inosanganisira maHVAC, pombi dzemhepo, mabhodhoro egasi nezvimwe.
Danho 2: Pressure Switch Calibration
Kurongeka kwakaringana kwechishandiso kwakakosha kuti uone uye kugadzirisa zvikanganiso mu switch point uye deadband. Uye zvakare, kuenzanisa kunochengetedza nguva nekudzikisa huwandu hwemidziyo inoshandiswa. Ini ndinokurudzira kusarudza iyo calibrator chaiyo kuti iite otomatiki maitiro ekugadzirisa. (1)
Ikozvino batanidza calibrator (kana DMM) kune yakajairwa uye inowanzovhura inobuda materminal eiyo pressure switch.
Iyo DMM calibrator inoyera "yakavhurika dunhu". Zvakare, ita shuwa kuti DMM calibrator inokwanisa kubata voltage iri kuyerwa - pakuyera AC voltage.
Nhanho 3 Batanidza iyo yekumanikidza switch kune yekumanikidza sosi.
Iwe unogona kubatanidza shanduko yekumanikidza kune pombi yeruoko yakasungirirwa kune geji yekumanikidza.
Kuwedzera kumanikidza
Nhanho 4: Wedzera kudzvanywa kwekumanikidza switch
Wedzera iyo sosi yekumanikidza kune yekumanikidza switch yekumisikidza kusvika iyo (iyo yekumanikidza switch) yachinja nyika kubva "yakavharwa" kuenda "kuvhurika". Rekodha kukosha kwekumanikidza pakarepo mushure meDMM inoratidza "pfupi wedunhu"; zvisinei, paunenge uchishandisa calibrator, ichanyora kukosha - haufaniri kuinyora nemaoko.
Kudonha pressure
Danho 5: Zvishoma nezvishoma kuderedza relay pressure
Simudza kudzvanywa kune yakanyanya switch pressure. Wobva wadzikisira kudzvanya zvishoma nezvishoma kusvika shanduko yekudzvanya yachinja kubva pakavharwa kuvhura. Nyora pasi kukosha kwekumanikidza. (2)
Dead band kuverenga
Nhanho yechitanhatu: Verenga iyo Deadband Threshold
Rangarira iwo anotevera ekumanikidza maitiro awakanyora mumatanho apfuura:
- Set Pressure - Yakarekodhwa sezvo kumanikidza kunowedzera.
- Set pressure - Yakarekodhwa kana kudzvanywa kwadonha.
Nenhamba mbiri idzi, unogona kuverenga iyo deadband pressure uchishandisa formula:
Dead band pressure = Musiyano pakati pekukwira kwekumanikidza setpoint uye yekudonha yekumanikidza kuburitsa poindi.
Mhedzisiro yekukosha kwenzvimbo yakafa
Chinangwa chikuru chekuve nebhendi yakafa (yakasiyana pakati pekumanikidza kuwedzera uye kudzikira mapoinzi) kudzivirira switch bounce. Bhandi rakafa rinounza kukosha kwechikumbaridzo apo magetsi anofanira kuvhura kana kuvhara.
Nokudaro, nokuda kwekushanda kwakakodzera, shanduko yekumanikidza inofanira kuva nenzvimbo yakafa. Kana iwe usina bhendi rakafa, yako yekumanikidza switch yakashata uye inoda kutsiviwa kana kugadziriswa, zvichienderana nekukuvadzwa.
Summing up
Sezvambotaurwa, chikumbaridzo chekumanikidza kwenzvimbo yakafa inofanirwa kuve yakakosha pakushanda kwakaringana kwekudzvanya switch uye mudziyo waunoshanda nawo. Maitiro acho ari nyore: gadzira iyo yekumanikidza switch, ibatanidze kune mudziyo, wedzera kudzvanywa, kuderedza kudzvanywa, rekodha yekumanikidza setpoint kukosha uye kuverenga iyo deadband chikumbaridzo.
Ini ndinotenda kuti nhanho dzakadzama uye pfungwa dzegwaro iri rinokubatsira iwe kuyedza kudzvanya switch nenzira iri nyore uye kunzwisisa kukosha kwayo.
Tarisa zvimwe zvezvinyorwa zvedu pazasi.
- Ungabatanidza sei 3-waya AC pressure switch
- Maitiro ekuyedza switch yemwenje ine multimeter
- Ndeipi waya yekubatanidza mabhatiri maviri e12V akafanana?
