Isimiso kanye nokusetshenziswa kwe-Negative Pressure Gauge

Igeji yengcindezi engalungile, eyaziwa nangokuthi i-vacuum gauge, iyithuluzi elisetshenziselwa ukukala ingcindezi engaphansi komfutho womoya. Isetshenziswa kabanzi emikhakheni ehlukahlukene yocwaningo lwezimboni nesayensi, njengamakhemikhali, ezokwelapha, ukuvikelwa kwemvelo, i-aerospace nokunye. Izikali zokucindezela ezimbi zinganikeza ulwazi olubalulekile mayelana nezinga le-vacuum ohlelweni, okubalulekile ukuqinisekisa ukusebenza okuvamile kwemishini kanye nokuphepha kwenqubo. Kuleli phepha, sizokwethula isimiso sokusebenza segeji yengcindezi engalungile, izinhlobo, izicelo kanye nokucatshangelwa ekusebenzeni.

Umgomo wokusebenza wegeji yengcindezi engalungile

Umgomo oyisisekelo wokusebenza wegeji yengcindezi engalungile ukunquma izinga le-vacuum ngokulinganisa umehluko wengcindezi phakathi kwendawo elinganisiwe nomfutho womoya. Iningi legeji yengcindezi engalungile liqukethe i-diaphragm yensimbi evaliwe, uhlangothi olulodwa lwe-diaphragm luxhunywe kumthombo wengcindezi ongemuhle olinganisiwe, olunye uhlangothi luvulekele imvelo yokucindezela komkhathi. Uma ingcindezi yendawo elinganisiwe iphansi kunomfutho womoya, i-diaphragm iyashintsha ngenxa yomehluko wengcindezi. Lokhu kuguqulwa kuguqulwa ukuxhumanisa komshini kube ukunyakaza kwesikhombi, okubonisa inani lokucindezela kokudayela.

Izinhlobo zegeji ye-pressure gauge

1. Igeji yokukala ingcindezi engalungile yemishini: lolu uhlobo oluvame kakhulu, olukala futhi lubonise ingcindezi ngokuguqulwa komzimba. Izinzuzo ziyisakhiwo esilula, izindleko eziphansi, akukho ukunikezwa kwamandla, kodwa ukunemba nokuzinza kuncane kakhulu.
2. Isilawuli se-air pressure digital: Isebenzisa izinzwa nezinto zikagesi ukukala ingcindezi futhi inganikeza ukunemba okuphezulu nokuzinza. I-Digital Negative Pressure Gauges ivamise ukuhlonyiswa ngesibonisi se-LCD, esingabonisa ulwazi olwengeziwe, njengamathrendi okucindezela, ukuqoshwa okuphezulu, nokunye.
3. I-Capillary Negative Pressure Gauge: Isebenzisa umehluko wokuphakama koketshezi eshubhuni le-capillary ukukala ingcindezi. Lolu hlobo lwegeji yengcindezi engalungile luvame ukusetshenziswa elabhorethri, ngoba umfutho ophansi kakhulu unganikeza nokunemba kokulinganisa okuphezulu.

Ukusetshenziswa kwegeji ye-pressure gauge

1. Imboni yamakhemikhali: Enqubweni yokukhiqiza amakhemikhali, ukusabela okuningi kudinga ukwenziwa ngaphansi kwezimo ezithile zengcindezi, igeji yengcindezi engalungile isetshenziselwa ukuqapha nokulawula ukucindezela kwe-reactor ukuqinisekisa ukuphepha nokuthuthukisa isivuno.
2. Imishini yezokwelapha: Emkhakheni wezokwelapha, ama-gauge okucindezela okungalungile avame ukusetshenziswa emishini yokudonsa kanye nama-ventilators ukuze kuqashwe futhi kulawule amandla okucindezela okungalungile ukuze kuqinisekiswe ukuphepha kwesiguli.
3. Ukuqapha indawo ezungezile: Ekuqaphelweni kwemvelo, amageji okucindezela okungalungile asetshenziselwa ukubona izinguquko zengcindezi ezindaweni ezivaliwe, ezifana nemishini yokusampula engcolile.
4. I-Aerospace: Emkhathini we-aerospace, ama-gauge okucindezela okungalungile asetshenziselwa ukuqapha ingcindezi yemvelo kumkhumbi-mkhathi ukuze kuqinisekiswe ukuphepha kwempahla nabasebenzi.

5. Ukusetshenziswa kwezinyathelo zokuphepha zegeji ye-pressure gauge

   1. Ukulinganisa okuvamile: Ukuze kuqinisekiswe ukunemba kwesilinganiso, igeji yokucindezela okunegethivu idinga ukulinganiswa njalo. Ukushintsha kwezinga lokushisa nokuswakama endaweni kungase kuthinte ukunemba kwegeji yengcindezi engalungile.
   2. Ukufaka okulungile: Uma ufaka igeji yengcindezi engalungile, udinga ukuqinisekisa ukuthi ukuxhumana phakathi kwayo nesistimu elinganisiwe kuvalwe kahle ukuze kugwenywe ukuvuza, okubaluleke kakhulu ekulinganiseni okuphansi-kokucindezela.
   3. Izinyathelo zokuzivikela: uma usebenzisa igeji yokucindezela okungekuhle ekushiseni okuphezulu, ezindaweni ezibolayo noma ezinomswakama, kungase kudingeke izinyathelo zokuzivikela ezengeziwe, njengokusetshenziswa kwezinto ezikhethekile ezenziwe ngamageji okucindezela okungalungile noma ukufakwa kwezembozo zokuzivikela.

   Isiphetho

   I-negativei-pressure gaugeiyithuluzi eliwusizo kakhulu elidlala indima ebalulekile emikhakheni eminingana. Ukuqonda ukuthi isebenza kanjani, izinhlobo ezahlukene kanye nendlela yokuyisebenzisa nokuyigcina ngendlela efanele kubalulekile ekunikezeni umdlalo ogcwele emsebenzini wayo kanye nokwelula impilo yayo yesevisi. Ngokuthuthuka kobuchwepheshe, ukunemba nokusebenza kwezikali zokucindezela okungalungile kuhlale kuthuthukiswa, kunikeze ithuba lezinhlelo eziningi eziyinkimbinkimbi nezintekenteke.
