Kweli phepha, siya kwazisa umgaqo osebenzayo we-gauge yoxinzelelo olubi, iintlobo, izicelo kunye neengqwalasela ekusebenzeni.

Umgaqo osebenzayo wegeyiji yoxinzelelo olubi

Umgaqo osisiseko wokusebenza wegeyiji yoxinzelelo olubi kukumisela inqanaba le-vacuum ngokulinganisa umahluko woxinzelelo phakathi kokusingqongileyo okulinganisiweyo kunye noxinzelelo lwe-atmospheric. Uninzi lwegeyiji yoxinzelelo olubi lubandakanya i-diaphragm yensimbi etywiniweyo, elinye icala le-diaphragm liqhagamshelwe kumthombo olinganisiweyo woxinzelelo olubi, elinye icala livuleleke kwindawo yoxinzelelo lwe-atmospheric. Xa uxinzelelo lommandla olinganisiweyo luphantsi kunoxinzelelo lwe-atmospheric, i-diaphragm iguqula ngenxa yokwahlukana koxinzelelo. Olu tshintsho luguqulwa ngokudibanisa komatshini kwintshukumo yesalathisi, ebonisa ixabiso loxinzelelo kwi-dial.

Iintlobo zegeyiji yoxinzelelo olubi

1. Igeyiji yoxinzelelo lweMechanical negative: olu lolona hlobo luqhelekileyo, olulinganisa kwaye lubonise uxinzelelo ngokuguqulwa komzimba. Iinzuzo zisakhiwo esilula, ixabiso eliphantsi, akukho mbane, kodwa ukuchaneka kunye nokuzinza kuncinci.
2. Umlawuli woxinzelelo lomoya wedijithali: Isebenzisa i-sensor kunye ne-electronics ukulinganisa uxinzelelo kwaye inokubonelela ngokuchaneka okuphezulu kunye nokuzinza. I-Digital Negative Pressure Gauges idla ngokuxhotyiswa ngomboniso we-LCD, onokubonisa ngokubonakalayo ulwazi oluninzi, olufana neendlela zoxinzelelo, ukurekhoda okuphezulu, njalo njalo.
3. I-Capillary Negative Pressure Gauge: Isebenzisa umahluko kubude bolwelo kwityhubhu ye-capillary ukulinganisa uxinzelelo. Olu hlobo lwegeyiji yoxinzelelo olubi ludla ngokusetyenziswa elabhoratri, kuba uxinzelelo oluphantsi kakhulu lunokubonelela ngokuchaneka komlinganiselo ophezulu.

Ukusetyenziswa kwegeyiji yoxinzelelo olubi

1. Ishishini lemichiza: Kwinkqubo yokuvelisa imichiza, iimpendulo ezininzi kufuneka zenziwe phantsi kweemeko ezithile zoxinzelelo, igeyiji yoxinzelelo olubi isetyenziselwa ukubeka iliso nokulawula uxinzelelo lwe-reactor ukuqinisekisa ukhuseleko kunye nokuphucula isivuno.
2. Izixhobo zonyango: Kwicandelo lezonyango, iigeji zoxinzelelo olubi zisetyenziswa ngokuqhelekileyo kwizixhobo zokufunxa kunye ne-ventilators ukubeka iliso kunye nokulawula amandla oxinzelelo olubi ukuqinisekisa ukhuseleko lwesigulane.
3. Ukubeka iliso kokusingqongileyo: Ekubekeni iliso kokusingqongileyo, iigeyiji zoxinzelelo olubi zisetyenziselwa ukubona utshintsho loxinzelelo kwiindawo ezivaliweyo, ezifana nezixhobo zesampulu ezingcolisayo.
4. I-Aerospace: Kwibala le-aerospace, iigeyiji zoxinzelelo olubi zisetyenziselwa ukubeka esweni uxinzelelo lokusingqongileyo kwi-spacecraft ukuqinisekisa ukhuseleko lwezixhobo kunye nabasebenzi.

5. Ukusetyenziswa kweendlela zokuthintela uxinzelelo olubi

   1. Ukulinganisa rhoqo: Ukuze kuqinisekiswe ukuchaneka komlinganiselo, igeyiji yoxinzelelo olubi kufuneka ilinganiswe rhoqo. Ubushushu kunye nokutshintsha komswakama kwimo engqongileyo kunokuchaphazela ukuchaneka kwegeyiji yoxinzelelo olubi.
   2. Ufakelo oluchanekileyo: Xa ufaka igeyiji yoxinzelelo olubi, kufuneka uqinisekise ukuba uxhulumaniso phakathi kwayo kunye nenkqubo elinganisiweyo ivalwe kakuhle ukuphepha ukuvuza, okubaluleke kakhulu kumlinganiselo ophantsi - woxinzelelo.
   3. Amanyathelo okukhusela: xa usebenzisa i-gauge ye-negative gauge kwiqondo lokushisa eliphezulu, iindawo ezinobungozi okanye ezinomswakama, iindlela ezongezelelweyo zokukhusela zingafuneka, ezifana nokusetyenziswa kwezinto ezikhethekileyo ezenziwe ngemilinganiselo yoxinzelelo olubi okanye ukufakwa kwezikhuselo zokukhusela.

   Ukuqukumbela

   I-negativeigeyiji yoxinzelelosisixhobo esiluncedo kakhulu esidlala indima ebalulekileyo kwiinkalo ezininzi. Ukuqonda indlela esebenza ngayo, iintlobo ezahlukeneyo kunye nendlela yokuyisebenzisa nokuyigcina ngokuchanekileyo kubalulekile ekunikezeni umdlalo opheleleyo kumsebenzi wayo kunye nokwandisa ubomi bayo benkonzo. Ngophuhliso lwetekhnoloji, ukuchaneka kunye nokusebenza kweegeyiji zoxinzelelo olubi zihlala ziphuculwa, zibonelela ngamathuba oluhlu olubanzi lwezicelo ezinzima nezibuthathaka.
