Nhanganyaya kuPressure Instrumentation

Kunzwisisa pressure instrumentation kwakakosha mune dzakasiyana siyana maindasitiri maapplication, kubva ku process control kusvika kune yekuchengetedza masisitimu. Gwaro iri rinopa mucherechedzo wakajeka wezvakajairwa zvekuyeresa midziyo yekuyeresa, misimboti yavo yekushanda, uye yakajairika maapplication. Chikamu chega chega chakagadzirirwa kurerutsa pfungwa dzakaoma, kuita kuti kudzidza kubudirire uye kuve nekuita.

1. Bourdon Tube Pressure Gauge

Inowanzo shandiswa mumaindasitiri masisitimu, senge mabhailers, Bourdon chubhu pressure gauges inoshanda pamusimboti weyakakombama, hollow chubhu inokanganisa pasi pekumanikidzwa kwemukati.

Working Principle:

• Mvura yakamanikidzwa inopinda muBourdon chubhu yakakomberedzwa.
• Iyo chubhu inotwasanudza zvishoma, ichiendesa kufamba uku kuburikidza nehurongwa hwe:
  • Kubatanidza tsvimbo
  • Chikamu uye pinion giya
  • Pointer uye dial
• Iyo pointer inozonyatso ratidza kukosha kwekumanikidza pane yakatemerwa dial.

Accuracy Giredhi:

Kururama kunotsanangurwa sechikamu chechiyero chakazara chemhosho inotenderwa.

• Magiredhi akajairika anosanganisira: 0.5, 1.0, 1.5, 2.0, uye 2.5.
• Nhamba yegiredhi yakaderera inoratidza huchokwadi hwepamusoro.
• Magiredhi 3 ne4 haawanzo shandirwa mumashandisirwo akaomarara senge masisitimu ebhailer nekuda kwekudzika kwawo.

2. Electric Contact Pressure Gauge

Ichi chiridzwa ishanduro yakakwidziridzwa yeBourdon pressure gauge, inobatanidza magetsi anobatika kuti ape yakakosha alarm uye kutonga mashandiro.

Features:

• Akashongedzerwa neaviri ekumusoro uye epasi ekupedzisira madhiri.
• Inoparira alarm kana mhinduro otomatiki kana zvikumbaridzo zvapfuudzwa.
• Inogona kuve yakasanganiswa isina musono nerelays uye macontactor kune yakazara otomatiki kudzora.
• Kunyanya kushanda munzvimbo dzinodiwa dzakadai semafuta uye gasi boiler masisitimu.

3. Capacitive Pressure Sensor

Aya ma sensors akaomarara anoona kudzvanywa nekunyatso kuyera shanduko ye capacitance inokonzerwa ne deformation ye flexible diaphragm.

Working Principle:

• Dzvinyiriro inoshandiswa inoita kuti diaphragm inoshanduka iende.
• Uku kutamiswa kunoshandura zvakananga capacitance pakati pemahwendefa maviri.
• Chiratidzo chinobuda chinobva chashandurwa nenzira kwayo kuita inoyerwa kubuda kwemagetsi.

Mhando:

• Inowanikwa mune ese ari maviri-apera uye akasiyana magadzirirwo.
• Differential pressure sensors inowanzo ratidza zvakapetwa kaviri kunzwisiswa kwemhando dzinenge dzimwechete.

Zvakanakira:

• Kunzwa kwakanyanya, kugonesa kuyerwa chaiko.
• Kurumidza kupindura kumhanya kune dynamic application.
• Yakanakisa kupikisa kuvhunduka uye vibration.
• Nyore uye yakasimba dhizaini yekugadzira.

4. Bellows Pressure Gauge

Iyi geji isarudzo yakanakira kuyera kusajeka kudzvanywa shanduko, kunyanya inokodzera boiler ventilation masisitimu uye mapaipi egasi.

Working Principle:

• Dzvinyiriro inopinda mugomba rakasarudzika.
• Iwo mabhero anowedzera, achigadzira chaiyo mechanic kusimuka.
• Uku kufamba kunobva kwafambiswa nenzira kwayo kune chinongedzo kuburikidza negiya mashini.
• Kuverenga kwekumanikidza kunoratidzwa zvakananga pane dial yechiridzwa.

5. Pressure Thermometers

Izvi zviridzwa zvakabatanidzwa zvinoshandisa yakavharwa sisitimu yakazadzwa nemvura yakati kuti inyatso kushandura shanduko yetembiricha kuita kuverenga kunowirirana.

Zvikamu:

• Chikamu (probe) chakaiswa zvine hungwaru mukati menzvimbo yetembiricha kuti chitariswe.
• A capillary chubhu yakagadzirirwa kutakura kudzvinyirira kuchinja.
• Bourdon tube, iyo inopindirana nekuchinja kwekumanikidzwa kunoparidzirwa.
• Chinongedzo chinonyatso ratidza tembiricha pane yakabatidzwa dial.

Fluids Yakashandiswa:

• Inowanzozadzwa nezvinwiwa, chiutsi, kana magasi akadai senitrogen (yakasarudzwa pakugadzikana kwayo).
• Nzvimbo yekushanda inowanzobva pa -100°C kusvika +500°C.

Applications:

• Yakakosha pakuenderera tembiricha yekutarisa uye otomatiki switching mabasa.
• Inoshandiswa zvakanyanya kudzora maseketi mukati meakasiyana maindasitiri masisitimu.

6. Strain Gauge Pressure Sensors

Aya chaiwo ma sensors anokwirisa majeji ekuyeresa kushandura ma mechanical strain zvakananga kuita shanduko dzinoyerwa mukuramba kwemagetsi.

Key Elements:

• Yekuyera geji yakasungirirwa zvine hungwaru kune dhiri-sensitive substrate.
• Iyo substrate inokanganisa pasi pekumanikidzwa kwakaiswa, nekudaro ichishandura kushorwa kweiyo strain gauge.
• Kazhinji inoshandisa Wheatstone bhiriji reketi yekuyera chaiyo yekuchinja shanduko.
• Chiratidzo chinobuda chinobva chakwidziridzwa uye kudhijitariswa kuti chinyatsobuda.

Kusiyana:

• Inowanikwa mune ese simbi foil uye semiconductor marudzi.
• Metal foil mhando dzinosanganisira waya uye foil subtypes.

Shandisa Nyaya:

• Yakanakisa yekubatanidza isina musono mune yemazuva ano dhijitari control system.
• Inopa kurongeka kwepamusoro uye yakanyatso kuchinjika kune inoshanduka kuyerwa maapplication.

Mhedziso: Kudzidza Kwekuona, Maoko-paUnyanzvi

Kunyangwe iwe uri mutsva pakushandisa chiridzwa kana kungozorodza ruzivo rwako, aya animated dhizaini ezviridzwa madhairekitori akagadzirirwa kukubatsira nekukurumidza kubata pfungwa dzakakosha uye kuvaka kunzwisisa kunoshanda.

Ramba wakagadzirirwa mamwe madhairekitori akareruka padanho, kuyerera, uye ongororo zviridzwa-zvese zvakagadzirirwa kuita kuti otomatiki yekudzidza isangodzidzisa chete asiwo inakidze zvechokwadi.
