Indlela yokukhetha i-pressure transmitter

Ekulawuleni okuzenzakalelayo kwezimboni nokulawulwa kwenqubo,izinzwa zokucindezela  dlala indima ebalulekile. Ukuthi ukuqapha umfutho kawoyela emishinini engumshini noma ukulawula ukugeleza kwegesi ezinhlelweni zesimo somoya, izinzwa zokucindezela zinikeza ukwesekwa kwedatha okunembile. Leli phepha lixoxa ngokubaluleka kokukhetha inzwa yokucindezela, lethula izinhlobo ezimbalwa ezijwayelekile zezinzwa zokucindezela (okuhlanganisa i-silicon pressure transmitter ehlukanisiwe, i-oyela pressure transmitter, i-air conditioning pressure transmitter, i-air compressor pressure transmitter, i-pressure press pressure transmitter, i-2088 meter head pressure transmitter kanye ne-differential pressure. transmitter), kanye namazinga abo okukhetha kanye nezimo zohlelo lokusebenza.

1. ukubaluleka kokukhetha inzwa yokucindezela

Inzwa yokucindezela iyingxenye ebalulekile ohlelweni lwezimboni ezishintshayo, ukunemba nokuthembeka kwayo kuthinta ngqo ukuzinza nokuphepha kwayo yonke inqubo yokukhiqiza. Ngakho-ke, ohlelweni lokukhetha, kuyadingeka ukucabangela ngokugcwele izidingo ezithile zesimo sohlelo lokusebenza, njengobubanzi bokulinganisa, izidingo zokunemba, ukuguquguquka kwemvelo nezinye izici, ukuqinisekisa ukuthi inzwa ekhethiwe ingahlangabezana nezidingo zokukhiqiza kwangempela.

2. izinhlobo zezinzwa ezivamile nezici

Isidluliseli somfutho we-silicon esabalalisiwe:  Ukusebenzisa izakhiwo ze-silicon ukuguqula ingcindezi ibe amasignali kagesi, ngokunemba okuphezulu, ukuqina kanye nezici zokuphendula okusheshayo. Isetshenziswa kabanzi ku-petrochemical, ukucubungula ukudla, ukwelashwa kwamanzi neminye imikhakha.

I-Oil pressure Transmitter: Isetshenziselwa ngokukhethekile ukuqapha ingcindezi kawoyela emishinini eyimishini ukuze kuqinisekiswe ukusebenza okujwayelekile kwemishini. Ukwakheka kwayo okuhlangene, ukufakwa okulula, okufanelekile endaweni ehlukahlukene yokusebenza eyinkimbinkimbi.

: 

I-air conditioning pressure transmitter: ukuqapha kwesikhathi sangempela sokushintsha kwengcindezi ohlelweni lwe-air conditioning kanye nokuguqulwa kube okukhipha ugesi. Ngezici zokuzwela okuphezulu, ukuphendula okusheshayo nokunemba okuphezulu, kuyingxenye ebalulekile yokulawula okuzenzakalelayo kwesistimu ye-air conditioning.

I-air compressor pressure transmitter : esetshenziselwa ukuqapha ingcindezi yegesi ohlelweni lwe-compressor yomoya ukuqinisekisa ukuzinza nokuphepha kokusebenza kwesistimu. Ikhono layo lokulwa nokuphazamiseka liqinile, lifanele izinga lokushisa eliphezulu, umswakama ophezulu kanye nezinye imvelo enokhahlo.

Imishini yokudla i-pressure transmitter:  enqubweni yokucubungula ukudla, okusetshenziselwa ukuqapha izinguquko zengcindezi kumishini ukuze kuqinisekiswe ikhwalithi yomkhiqizo nokusebenza kahle kokukhiqiza. Lolu hlobo lwenzwa ngokuvamile lwenziwa ngezinto ezimelana nokugqwala ukuze zivumelane nendawo ekhethekile yemboni yokudla.

I-2088 Gauge pressure transmitter:  Ikhwalithi ephezulu, izindleko eziphansi, ezifanele izinhlelo zokusebenza ezihlukahlukene zezimboni. Izinto zayo eziyinhloko zobuchwepheshe besifunda zithuthukisiwe, zivalwe futhi zelashwa zihlukaniswe ngokuphelele ngaphandle, futhi zingahlangabezana nezidingo zobufakazi bomswakama, amanzi, ukuqhuma nezinye izimo ezinzima.

I-Differential pressure Transmitter: esetshenziselwa ukukala igesi, umusi noma umehluko wengcindezi ye-liquid, esetshenziswa kabanzi kumakhemikhali, amandla kagesi, imithi kanye neminye imikhakha yokugeleza, izinga le-liquid, izinga lokushisa, ingcindezi kanye neminye imingcele yokuthola nokulawula.

3. Amazinga okukhetha kanye nezimo zohlelo lokusebenza

Enqubweni yokukhetha, izici ezilandelayo kufanele zibhekwe:

Ibanga lokulinganisa: Khetha ububanzi bokulinganisa obufanele obususelwe kuzimfuneko zezimo ezingokoqobo zohlelo lokusebenza.

Izidingo zokunemba: Ngokuya ngezidingo zokunemba zedatha yokulinganisa, khetha inzwa enokunemba okuhambisanayo.

Ukuvumelana nezimo kwendawo: Cabangela izinga lokushisa, umswakama, ukugqwala nezinye izici zendawo lapho inzwa itholakala khona, bese ukhetha uhlobo lwenzwa olufanele.

Inani/Isilinganiso sokusebenza: ngaphansi kwesisekelo sokuhlangabezana nesidingo, cabangela intengo nezindleko zokunakekelwa kwenzwa.

Ngokwalezi zindinganiso ezingenhla, kuhlanganiswe nezidingo zezimo zangempela zohlelo lokusebenza, khetha uhlobo lwenzwa yokucindezela olufaneleka kakhulu. Isibonelo, embonini ye-petrochemical, ungakhetha phakathi kwe-silicon pressure transmitter ehlukanisiwe noma i-2088 gauge pressure transmitter; Embonini yokucubungula ukudla, ama-transmitter okucindezela imishini yokudla angakhethwa; Kuhlelo lwe-air conditioning, ungakhetha i-air conditioning pressure transmitter.
