Mau oyamba a Pressure Instrumentation

Kumvetsetsa zida zokakamiza ndizofunikira kwambiri pamagwiritsidwe osiyanasiyana amakampani, kuyambira pakuwongolera njira kupita kumakina achitetezo. Bukhuli limapereka chithunzithunzi chodziwika bwino cha zida zoyezera kuthamanga, mfundo zake zogwirira ntchito, ndi momwe amagwiritsidwira ntchito. Gawo lirilonse lapangidwa kuti likhale losavuta mfundo zovuta, kupangitsa kuphunzira kukhala kogwira mtima komanso kochititsa chidwi.

1. Bourdon Tube Pressure Gauge

Nthawi zambiri amagwiritsidwa ntchito m'mafakitale, monga ma boilers, ma Bourdon chubu pressure gauges amagwira ntchito potsata mfundo ya chubu yopindika, yopanda pake yomwe imapindika pansi pa kupanikizika kwamkati.

Mfundo Yogwirira Ntchito:

• Madzi opanikizika amalowa mu chubu cha Bourdon chopindika.
• Chubu chimawongoka pang'ono, ndikusuntha kusunthaku kudzera mu dongosolo la:
  • Chingwe cholumikizira
  • Segment ndi pinion gear
  • Pointer ndi kuyimba
• Cholozeracho chimawonetsa ndendende kuchuluka kwa kuthamanga kwa kuyimba kokhazikika.

Mlingo Wolondola:

Kulondola kumatanthauzidwa ngati kuchuluka kwa sikelo yonse ya cholakwika chololeka.

• Magiredi wamba akuphatikizapo: 0.5, 1.0, 1.5, 2.0, ndi 2.5.
• Nambala yotsika imasonyeza kulondola kwakukulu.
• Magiredi 3 ndi 4 sagwiritsidwa ntchito kawirikawiri m'mapulogalamu ovuta kwambiri monga makina otenthetsera chifukwa chakuchepa kwawo.

2. Magetsi Kukhudza Pressure Gauge

Chida ichi ndi mtundu wowongoleredwa wa Bourdon pressure gauge, kuphatikiza zolumikizirana ndi magetsi kuti zipereke ma alarm ofunikira ndikuwongolera magwiridwe antchito.

Mawonekedwe:

• Okonzeka ndi onse chapamwamba ndi m'munsi malire kulankhula.
• Imayambitsa alamu kapena kuyankha kodziwikiratu pamene mipata yokakamiza yadutsa.
• Itha kuphatikizidwa mosasunthika ndi ma relay ndi ma contactors kuti muzitha kuwongolera kwathunthu.
• Makamaka m'malo ovuta monga makina opangira mafuta ndi gasi.

3. Capacitive Pressure Sensor

Masensa apamwambawa amazindikira kupanikizika poyesa molondola kusintha kwa capacitance chifukwa cha kusinthika kwa diaphragm yosinthika.

Mfundo Yogwirira Ntchito:

• Kupanikizika kogwiritsidwa ntchito kumapangitsa kuti diaphragm yosinthika ichoke.
• Kusamuka uku kumasintha mwachindunji capacitance pakati pa mbale ziwiri.
• Chizindikiro chotsatiracho chimasinthidwa molondola kukhala magetsi oyezera.

Mitundu:

• Imapezeka muzopanga zonse ziwiri komanso zosiyana.
• Masensa osiyanasiyana amphamvu nthawi zambiri amawonetsa pafupifupi kuwirikiza kawiri kukhudzika kwa mitundu yomaliza.

Ubwino:

• High sensitivity, kuloleza miyeso yolondola.
• Kuthamanga kwachangu pamapulogalamu osinthika.
• Kukaniza kwabwino kwa kugwedezeka ndi kugwedezeka.
• Mapangidwe osavuta komanso olimba.

4. Bellows Pressure Gauge

Geji iyi ndi njira yabwino yoyezera kusintha kosawoneka bwino kwamakamaka, makamaka koyenera pamakina opumira ndi mpweya komanso mapaipi a gasi.

Mfundo Yogwirira Ntchito:

• Kupsyinjika kumalowa mwapadera mavuvu patsekeke.
• Mavuvu amakula, kupangitsa kusamutsidwa koyenera kwamakina.
• Kuyenda uku kumatumizidwa molondola kupita ku pointer kudzera pamakina amagetsi.
• Kuwerengera kwamphamvu kwamoyo kumawonetsedwa mwachindunji pa dial ya chida.

5. Ma thermometers a Pressure

Zida zophatikizikazi zimagwiritsa ntchito makina osindikizidwa odzazidwa ndi madzi enaake kuti asinthe kusintha kwa kutentha kukhala kuwerengera kofanana.

Zigawo:

• Chigawo (probe) chomwe chimayikidwa mwadongosolo m'dera la kutentha kuti liwunikire.
• Thumba la capillary lopangidwa kuti lizinyamula kusintha kwamphamvu.
• Bourdon chubu, yomwe imakhudzidwa ndi kusintha kwa kuthamanga komwe kumafalitsidwa.
• Cholozera chomwe chimasonyeza molondola kutentha kwa foni yamakono.

Madzi Ogwiritsidwa Ntchito:

• Nthawi zambiri amadzazidwa ndi zakumwa, nthunzi, kapena mpweya monga nayitrogeni (wosankhidwa chifukwa cha kukhazikika kwake).
• Kugwira ntchito nthawi zambiri kumayambira -100 ° C mpaka +500 ° C.

Mapulogalamu:

• Zofunikira pakuwunika kutentha kosalekeza ndi ntchito zosinthira zokha.
• Amagwiritsidwa ntchito kwambiri pakuwongolera mabwalo mkati mwa machitidwe osiyanasiyana amakampani.

6. Kupsyinjika Gauge Pressure Sensors

Masensa olondola kwambiri awa amathandizira ma geji amtundu kuti asinthe zovuta zamakina kukhala zosinthika zoyezeka pakukana kwamagetsi.

Zofunika Kwambiri:

• Chiyerekezo choyezera kupsinjika chomangika bwino pagawo losamva kupsinjika.
• Gawo lapansi limapunduka pansi pa kukanikiza kogwiritsidwa ntchito, motero kumasintha kukana kwa strain gauge.
• Nthawi zambiri amagwiritsa ntchito mabwalo a Wheatstone kuti athe kuyeza kolondola kwa kusintha kwa kukana.
• Chizindikiro chotsatiracho chimakulitsidwa ndikusinthidwa kuti chizituluka bwino.

Zosiyanasiyana:

• Amapezeka mumitundu yonse yazitsulo zachitsulo ndi semiconductor.
• Mitundu yazitsulo zazitsulo zimaphatikizaponso mawaya ndi zojambulazo.

Kugwiritsa Ntchito Milandu:

• Zabwino kwambiri pakuphatikizana kosasinthika mumayendedwe amakono owongolera digito.
• Imapereka kulondola kwakukulu ndipo imasinthidwa kuti igwiritsidwe ntchito poyezera mosinthasintha.

Kutsiliza: Kuphunzira Zowoneka, Maluso Ogwiritsa Ntchito Manja

Kaya ndinu ongoyamba kumene kuimba zida kapena mukungotsitsimula chidziwitso chanu, zida zotsatsira makanemawa zidapangidwa kuti zikuthandizeni kumvetsetsa mwachangu mfundo zazikuluzikulu ndikumvetsetsa bwino.

Khalani tcheru kuti mupeze maupangiri osavuta okhudza mulingo, mayendedwe, ndi zida zowunikira—zonse zidapangidwa kuti zipangitse kuphunzira kukhala kodziwitsa komanso kosangalatsa.
