Kuyeza kuthamanga kwa mpweya ndi kuyang'anira ndi gawo lofunika kwambiri pa ntchito zamakono zamafakitale. Kupanikizika komwe kumayesedwa kungatanthauzidwe ngati magulu osiyanasiyana kutengera momwe muyezera. Ngakhale kuti kuyeza kuthamanga kwa mpweya kungakhale kokwanira pa ntchito zambiri zamafakitale, nthawi zina gwiritsani ntchito chida chomwe chikuwonetsa kuthamanga kwa mpweya ndikofunikira.
Kupanikizika Konse ndi Kupanikizika kwa Gauge
Mlengalenga wa dziko lapansi uli ndi kulemera ndipo umapanga kupanikizika kokha. Kuchuluka kwa kupanikizika kwa mumlengalenga kumatchedwanso kuti ambient pressure, komwe kumasiyana pafupifupi 101.325kPa (mlengalenga wokhazikika) malinga ndi kutalika ndi nyengo. Kusiyana kwakukulu kwa kupanikizika kotheratu ndi kukakamiza kwa gauge kuli ngati kukakamizidwa kwa mumlengalenga kumaphatikizidwa. Mfundo yofunikira ya kupanikizika kwa gauge ndi kupsinjika kwa mumlengalenga pomwe kupsinjika kotheratu ndi malo opanda mpweya pomwe kupsinjika kwa mumlengalenga kulibe konse. Chifukwa chake kuwerenga kupsinjika kotheratu kumasonyeza kuchuluka kwa kupsinjika kwa mumlengalenga ndi kukakamiza kwa gauge.
Kupanikizika nthawi zambiri kumayesedwa poyesa kusintha kwa chinthu chozindikira, pomwe mbali imodzi ya chinthucho imawonetsedwa ku reference ndipo mbali inayo imakhudzana ndi processing medium. Pa gauge pressure sensor, mbali ya diaphragm yomwe sikugwirizana ndi medium imatulutsidwa kuti ifike ku ambient pressure, zomwe zimapangitsa kuti gauge pressure reading ikhale yosiyana pakati pa process ndi air pressure. Ndi absolute pressure sensor, diaphragm imawonetsedwa ku absolute vacuum champ yomwe imatsekedwa kosatha. Popeza sealed vacuum imagwiritsidwa ntchito ngati reference point, diaphragm deformation sikhudzidwa ndi mlengalenga.
Popeza mafakitale nthawi zambiri amakhala ndi kukwera kofanana ndipo kugwiritsa ntchito mphamvu zawo sikukhudzidwa ndi kusintha kwa mphamvu ya mpweya, muyeso woyezera mphamvu ya mpweya ndi wolondola mokwanira pazinthu zambiri. Komabe, zochitika zapadera zimafuna mphamvu ya mpweya, yomwe siili yosiyana ndi kusinthasintha kwa mphamvu ya mpweya. Ma transmitter othamanga kwambiri nthawi zambiri amapezeka m'magawo a kukonza mankhwala, ndege, HVAC, makamaka chifukwa cha zifukwa zotsatirazi:
- ✦ Njirayi imafuna kusunga mpweya wopanda mpweya kapena mpweya wochepa kwambiri, zomwe zimapangitsa kuti pakhale kupanikizika kokwanira kuti pakhale mphamvu yeniyeni.
- ✦ Njirayi imadalira sublimation kapena outgas ndipo imafunika kudziwa mphamvu yeniyeni yomwe yatsala m'chipindamo kuti idziwe nthawi yomwe ntchitoyi yatha.
- ✦ Chombocho chimagwiritsidwa ntchito pansi pa vacuum kuti chichepetse kutentha kwapakati ndipo kuwongolera bwino kuthamanga kwa mpweya ndikofunikira.
- ✦ Pa nthawi yoyesa injini, kupanikizika mu intake manifold nthawi zambiri kumakhala kotsika kuposa kupsinjika kwa mpweya ndipo ndikofunikira powerengera kuchuluka kwa mpweya.
Shanghai Wangyuanndi wopanga komanso wogulitsa zida zoyezera waluso kwa zaka zoposa 20. Wangyuan imapereka mitundu yonse ya zida zoyezera.zotumizira mpweyakuti mupeze mayankho oyezera kuphatikiza absolute, gauge komanso differential pressure. Ngati muli ndi funso lililonse lokhudza kusankha ma absolute pressure transmitters, chonde musazengereze kutilankhulana nafe.
