Inzwa ifanele i-Dongfeng Cummins control valve 0928400712

Ukukhethwa kwezinzwa zokucindezela Izinzwa zesimanje ziyehluka kakhulu ngokomthetho nangesakhiwo.Indlela yokukhetha izinzwa ngokunengqondo ngokwenhloso ethile yokulinganisa, into yokulinganisa nendawo yokulinganisa inkinga yokuqala okufanele ixazululwe lapho kukalwa inani elithile.Lapho inzwa inqunywa, indlela yokulinganisa ehambisanayo kanye nemishini yokulinganisa nakho kunganqunywa.Impumelelo noma ukwehluleka kwemiphumela yokulinganisa kuncike kakhulu ekutheni ukukhethwa kwezinzwa kunengqondo yini.

Ukuhlaziywa komkhuba wokuthuthukiswa komsebenzi wenzwa yokucindezela;

1.Izinzwa eziguqula ukucindezela zibe amasignali kagesi ngokuvamile zibizwa ngokuthi izinzwa zokucindezela.Inzwa yokucindezela ngokuvamile iqukethe i-elementi ezwelayo enwebekayo kanye ne-elementi ezwelayo esuswayo (noma igeji yokulinganisa).Umsebenzi wenzwa enwebekayo ukwenza ingcindezi elinganisiwe endaweni ethile bese uyiguqulela ekufudukeni noma ukukhahlamezeka, bese uguqula inzwa yokufuduka (bona inzwa yokufuduka) noma igeji yokuhlunga (bona igeji yokulinganisa ukumelana negeji yokulinganisa ye-semiconductor) ibe yingcindezi- amasignali kagesi ahlobene.Ngezinye izikhathi, imisebenzi yalezi zakhi ezimbili ihlanganiswe, njengenzwa yokucindezela okuqinile kunzwa yokumelana nokucindezela.

I-2.Ukucindezela kuyipharamitha yenqubo ebalulekile kubuchwepheshe bokukhiqiza, i-aerospace kanye nemboni yezokuvikela kazwelonke.Ayidingi nje kuphela ukulinganisa okuguquguqukayo okusheshayo, kodwa futhi idinga ukuboniswa kwedijithali nokurekhodwa kwemiphumela yokulinganisa.Ukuzenzakalela kwezindawo ezinkulu zokuhluza uwoyela, izitshalo zamakhemikhali, izimboni zamandla nezitshalo zensimbi nakho kudinga ukudlulisa imingcele yengcindezi ukude, futhi kuguqule izinga lokushisa, ukugeleza, i-viscosity neminye imingcele yokucindezela ibe amasignali edijithali futhi ithumele kumakhompyutha.

I-3.Ngakho-ke, inzwa yokucindezela iyinzwa ebaluleke kakhulu futhi ekhula ngokushesha.Umkhuba wokuthuthuka wenzwa yokucindezela ukuthuthukisa isivinini sokuphendula esiguquguqukayo, ukunemba nokuthembeka, kanye nokubona ukwenziwa kwedijithali kanye nobuhlakani.Izinzwa zokucindezela ezivame ukusetshenziswa zihlanganisa inzwa yokucindezela i-capacitive, inzwa yokucindezela okuguquguqukayo (inzwa yokungafuni ukuguquguquka, inzwa yensimbi ye-metal analyzer differential transformer pressure sensor), inzwa yokucindezela kweHholo, inzwa yokucindezela i-fiber optical (inzwa ye-fiber optical), inzwa yokucindezela i-resonant njalonjalo.
