Wopanga Vacuum Piezoresistive Pressure Sensor Transmitter

Maziko akuluakulu osankhidwa a kukakamiza / kusiyana kwapanikiza：Kutengera ndi zinthu za sing'anga yoyezera, sankhani zinthu zomwe zimasunga ndalama komanso zosavuta kuziyika.Ngati sing'anga yoyezerayo ili ndi ma viscosity apamwamba, kapena osavuta kuyimitsa, kapena kunyezimira kwambiri, cholumikizira chakutali chiyenera kusankhidwa.

Posankha kachipangizo ka diaphragm, m'pofunika kuganizira za dzimbiri za sing'anga yamadzimadzi yomwe imayesedwa ndi chitsulo cha diaphragm. Ubwino wa diaphragm uyenera kukhala wabwino, apo ayi, diaphragm yakunja ndi flange zidzawonongeka pakapita nthawi yogwiritsidwa ntchito, zomwe zingayambitse zida kapena ngozi. Kusankhidwa kwa zinthu zamabokosi ndikofunikira kwambiri. The diaphragm ya transmitter imapangidwa ndi chitsulo chosapanga dzimbiri, 304 chitsulo chosapanga dzimbiri, 316/316L chitsulo chosapanga dzimbiri, tantalum ndi zina zotero. 

Kuphatikiza apo, kutentha kwa sing'anga yoyezera kuyenera kuganiziridwa. Ngati kutentha kuli kwakukulu, kufika pa 200 ° C mpaka 400 ° C, mtundu wa kutentha kwapamwamba uyenera kusankhidwa, apo ayi mafuta a silicone adzasungunuka ndikukula, zomwe zimapangitsa kuti muyesowo ukhale wolakwika.

Mphamvu yogwira ntchito ya zida ndi kukakamiza kwa transmitter ziyenera kugwirizana ndi ntchitoyo. Kuchokera pazachuma, zinthu za bokosi lakunja la membrane ndi gawo loyikapo ndizofunikira kwambiri, ndipo ndikofunikira kusankha choyenera, koma kulumikizana kwa flange kumatha kuchepetsa zofunikira zakuthupi, monga kugwiritsa ntchito kaboni. zitsulo, chrome plating, etc., zomwe zidzapulumutsa ndalama zambiri.

Ndikwabwino kugwiritsa ntchito ulusi wolumikizana ndi ma transmitters akutali, omwe amapulumutsa ndalama komanso osavuta kukhazikitsa.

Pakusankhidwa kwa ma transmitters ophatikizika wamba ndi ma transmitters osiyanitsa, kuwononga kwa sing'anga yoyezera kuyeneranso kuganiziridwa, koma kutentha kwa sing'anga yomwe imagwiritsidwa ntchito kumatha kunyalanyazidwa, chifukwa mtundu wamba umakanikizidwa muyeso, komanso kutentha kwa nthawi yayitali. ntchito ndi Kutentha kwa Malo, Koma mtundu wamba umagwiritsa ntchito kukonza kwambiri kuposa mtundu wakutali. Choyamba ndi vuto la kusunga kutentha. Kutentha kukakhala pansi pa ziro, chubu chowongolera kuthamanga chimaundana, ndipo chotumizira sichigwira ntchito kapena kuonongeka. Izi zimafuna kuwonjezera kufufuza kutentha ndi ma incubators.

Kuchokera pamalingaliro azachuma, posankha cholumikizira, bola ngati sing'angayo siyosavuta kuyimitsa, ma transmitter wamba atha kugwiritsidwa ntchito, komanso kuti pakhale zovuta zochepa zowunikira media, sing'anga yotsuka imatha kuwonjezedwanso pakuyezera kosalunjika ( malinga ngati ndondomekoyo ilola kugwiritsa ntchito madzi oyeretsa kapena gasi).Ma transmitters wamba amafunikira ogwira ntchito yosamalira kuti aziyendera pafupipafupi kuti atsimikizire ngati mapaipi osiyanasiyana owongolera akutuluka, kaya sing'anga yotsuka ndi yabwinobwino, kaya kuteteza kutentha kuli bwino, ndi zina zotero, bola ngati kukonza kuli bwino, ma transmitters ambiri wamba. idzapulumutsa ndalama zambiri kamodzi . Samalani kuphatikiza kukonzanso kwa hardware ndi kukonza zofewa panthawi yokonza.

Pankhani ya muyeso wa ma transmitter, nthawi zambiri ma transmitter amakhala ndi mitundu ingapo yosinthika, ndi bwino kuyika mitundu yomwe imagwiritsidwa ntchito mpaka 1/4 ~ 3/4 yamitundu yake, kuti kulondola kutsimikizike.,M'malo mwake, ntchito zina (mulingo wamadzimadzi) zimayenera kusamutsa miyeso ya chotumizira. Muyeso woyezera ndi kuchuluka kwa kusamuka kumawerengedwa molingana ndi malo oyika pamalowo kuti asamuke. Kusamuka kungagawidwe kukhala kusamuka kwabwino komanso kusamuka koyipa. Pakadali pano, ma transmitter anzeru akhala otchuka kwambiri. Amadziwika ndi kulondola kwakukulu, mitundu yayikulu yosinthika, komanso kusintha kosavuta komanso kukhazikika kwabwino. Kulingalira kowonjezereka kuyenera kuperekedwa pakusankhidwa.
