Inzwa yokucindezela isetshenziselwa ukukala ingcindezi yoketshezi namagesi.Ngokufanayo nezinye izinzwa, izinzwa zokucindezela ziguqula umfutho ube okukhipha ugesi lapho zisebenza.
Ukuhlukaniswa kwenzwa yokucindezela:
Izinzwa zokucindezela ekusetshenzisweni kobuchwepheshe, ukuklama, ukusebenza, izimo zokusebenza kanye namanani anomehluko omkhulu.Kulinganiselwa ukuthi kunezinzwa zokucindezela ezingaphezu kuka-60 zobuchwepheshe obuhlukahlukene kanye nezinkampani okungenani ezingu-300 ezikhiqiza izinzwa zokucindezela emhlabeni wonke.
Izinzwa zokucindezela zingahlukaniswa ngebanga lokucindezela ezingalinganisa, izinga lokushisa lokusebenza kanye nohlobo lokucindezela;Okubaluleke kakhulu uhlobo lokucindezela.Izinzwa zokucindezela zingahlukaniswa zibe izigaba ezinhlanu ezilandelayo ngokuya ngezinhlobo zengcindezi:
①, inzwa yokucindezela okuphelele:
Le nzwa yokucindezela ikala ingcindezi yangempela yomzimba wokugeleza, okungukuthi, ingcindezi ehlobene nokucindezela kwe-vacuum.Umfutho womkhathi ophelele ezingeni lolwandle ngu-101.325kPa (14.7? PSI).
②, inzwa yokucindezela kwegeji:
Le nzwa yokucindezela ingakala ingcindezi endaweni ethile ehlobene nomfutho womoya.Isibonelo salokhu isilinganiso somfutho wesondo.Uma i-gauge ye-pressure gauge ifundeka ngokuthi 0PSI, kusho ukuthi ingcindezi engaphakathi kwesondo ilingana nomfutho womkhathi, ongu-14.7PSI.
③, inzwa yokucindezela kwe-vacuum:
Lolu hlobo lwenzwa yokucindezela lusetshenziselwa ukukala ingcindezi ye-atmosphere engaphansi kweyodwa.Ezinye izinzwa zokucindezela kwe-vacuum embonini zifundeka ngokuhlobene nomoya owodwa (ukufunda okunegethivu), kanti ezinye zisekelwe phezu kwengcindezi yazo ephelele.
(4) Imitha yokucindezela ehlukile:
Leli thuluzi lisetshenziselwa ukukala umehluko wengcindezi phakathi kwezingcindezi ezimbili, njengomehluko phakathi kweziphetho ezimbili zesihlungi sikawoyela.Imitha yokucindezela ehlukile nayo isetshenziselwa ukukala izinga lokugeleza noma izinga loketshezi emkhunjini wokucindezela.
⑤, inzwa yengcindezi yokuvala:
Leli thuluzi lifana nenzwa yomfutho ongaphezulu, kodwa lilinganiswa ngokukhethekile ukuze kulinganiswe ingcindezi ehlobene nezinga lolwandle.
Uma ngokusho kwesakhiwo esihlukile kanye nesimiso, zingahlukaniswa zibe: uhlobo lwe-strain, uhlobo lwe-piezoresistive, uhlobo lwe-capacitance, uhlobo lwe-piezoelectric, inzwa yokucindezela imvamisa yohlobo lokudlidliza.Ngaphezu kwalokho, kukhona photoelectric, fibre optical, ultrasonic ingcindezi izinzwa.
