Ukadaulo wa chisindikizo cha diaphragm: woteteza chitetezo ndi magwiridwe antchito a mafakitale

Mu mafakitale a mankhwala, mafuta, mankhwala, ndi mafakitale ena, makhalidwe owononga kwambiri, kutentha kwambiri, kapena kuthamanga kwambiri kwa chipangizochi amachititsa kuti zipangizozi zikhale zovuta kwambiri. Zipangizo zachikhalidwe zopanikizika zimawonongeka mosavuta kapena kutsekedwa chifukwa chokhudzana mwachindunji ndi chipangizocho, zomwe zimapangitsa kuti muyeso ulephereke kapena ngakhale kuopsa kwa chitetezo. Ukadaulo wa chisindikizo cha diaphragm wakhala njira yofunika kwambiri yothetsera vutoli kudzera mu kapangidwe katsopano kodzipatula.

Pakatikati pa dongosolo lotsekera diaphragm pali kapangidwe kake kawiri: diaphragm ya zinthu zosagwira dzimbiri (monga chitsulo chosapanga dzimbiri ndi polytetrafluoroethylene) ndi madzi otsekera pamodzi amapanga njira yotumizira kupanikizika, yomwe imalekanitsa kwathunthu cholumikiziracho ndi sensa. Kapangidwe kameneka sikuti kamangoteteza sensayo ku zinthu zowononga monga ma acid amphamvu ndi alkali komanso imagwira bwino ntchito ndi kukhuthala kwakukulu komanso madzi osavuta kupangira ma crystalline. Mwachitsanzo, mu mankhwala a chlor-alkali, ma diaphragm pressure gauges amatha kuyeza kupsinjika kwa chlorine wonyowa mokhazikika kwa nthawi yayitali, kupewa kusintha zida zachikhalidwe pafupipafupi chifukwa cha dzimbiri la zinthu.

Kuphatikiza apo, kapangidwe kake ka ukadaulo wa chisindikizo cha diaphragm kamachepetsa kwambiri ndalama zokonzera. Zigawo za diaphragm zimatha kusinthidwa padera popanda kusokoneza chida chonsecho, zomwe zimachepetsa kwambiri nthawi yogwira ntchito. Pankhani yoyeretsa mafuta, kuyang'anira kuthamanga kwa zinthu zamafuta otentha kwambiri nthawi zambiri kumapangitsa kuti chida chachikhalidwe chitseke chifukwa cha kulimba kwa cholumikiziracho, pomwe njira yotsekera madzi yotumizira ma diaphragm system imatha kutsimikizira kupitiliza ndi kulondola kwa chizindikiro cha kuthamanga.

Ndi kukweza kwa makina odziyimira pawokha a mafakitale, ukadaulo wotseka diaphragm waphatikizidwa mu zida monga ma transmitter anzeru kuti akwaniritse kusonkhanitsa deta nthawi yeniyeni komanso kuyang'anira patali. Kupanikizika kwake kumaphimba vacuum mpaka zochitika zamphamvu kwambiri, zomwe zimapangitsa kuti ikhale yankho lofunikira kwambiri m'magawo owongolera njira zamakemikolo, kuwunika chitetezo cha mphamvu, ndi zina zotero.
