Chii geji? Pressure geji nokuti kuyera kumanikidzwa

Kazhinji, chisarudzo mumunda wefizikisi matambudziko akasangana navo namano zvakadai, akadai kumanikidza gauges. Asi chii chinonzi geji, sei akunoita uye chii mhando varipo? Hurukuro iyi nhasi.

Yakadaro kumanikidzwa geji?

Chishandiso ichi chakagadzirirwa kuyera gage kufurirwa. Zvisinei, kumanikidza angava akasiyana, uye saka pane gauges zvakasiyana. Somuenzaniso, nokuti kuyera mumhepo kumanikidzwa gauges inoshandiswa kuona kufurirwa musiyano aishandiswa differential kufurirwa gauges. Asi chero zvakadaro, ivo chete uyere kumanikidzwa.

Zvino hazvibviri kutsanangura zvose kushandisa zviridzwa izvi, nokuti mugove wavo. Vanogona kushandiswa mune motokari, zvokurima, matunhu neminisiparati uye chokugara kwemauto, mune chero zvokuimba zvokufambisa, simbi, etc. Zvichienderana chinangwa, pane marudzi akasiyana Data kuyera nhumbi, asi chaizvoizvo kwavo nguva dzose kunoderedza mumwe - kuyera kufurirwa.

Uyewo, mano aya rakakamurwa akasiyana zvichienderana nokuyerwa zano. Zvino kuti zvimwe kana zvishoma pachena kuti yakadaro kumanikidzwa geji, anogona endai mashoko. Zvikurukuru, isu tsanangura mhando uye dzavo mafomu.

Mhando dzvinyiriro gauges

Zvichienderana rwendo, kufurirwa gauges rinogona mhando dzakasiyana. Somuenzaniso, mvura kumanikidza gauges inoshandiswa kuyera kufurirwa mvura mbiru. Kune chitubu namano kuti anogona kuyera simba rikashandiswa. Pano, kumanikidza kunoonekwa kuburikidza vakadengezera simba yechirimo deformation.

Zvishoma nevakawanda misha gauges anogona kutaurwa, apo akayera kumanikidza iri mikwende pachishandiswa simba iyo anoita pamusoro pisitoni chikwata.

Onawo kuti zvichienderana nechinangwa uye mamiriro ezvinhu kushandiswa akabudisa mano zvinotevera:

• Technical - mukuru-chinangwa mudziyo.
• Test zvakagadzirirwa kuidza iiswe midziyo.
• Model - kuti bvunzo michina uye dzakaenzana, izvo zvaida yakawedzera kururama.

Uyewo, mano izvi zvinogona kupatsanurwa maererano muchitokisi wanda, kururama makirasi. Somuenzaniso, kururama kirasi gauges ndiwo: 0,15, 0.25, 0,4, 0,6, 1, 1.5, 2.5, 4. Pano, nhamba inosarudza rakarurama chiridzwa, uye sei zvichava yakaderera, mudziyo nomazvo.

chitubu

gages izvi zvakagadzirirwa kuti kuyera gage kumanikidzwa. Pfungwa dzavo yakayerwa inobva kushandisa chaiyo chitubu, izvo deforms zvaoma. Kukosha kugozha anenge maatomu akafanana (chitubu) vagara vandifungira kuverenga zano rinokosha, izvo zvinozoita ane kudzidza akamboona. On pamwero uyu, inodzidzisa anoona kukosha kuyerwa kumanikidzwa.

The nzwisisa chinhu gauges dzakadaro anoteererwa pamusoro inonzi Bourdon chubhu - vasanonoka kuroorwa dzokai yechirimo. Zvisinei, pane dzimwe zvinhu: a sandara chemarata Kamudzira multiturn tubular chitubu mvuto (garmonikoobraznaya Kamudzira). Vose vari zvakafanana vanobudirira, asi zvikuru nyore uye nyore, uye nokuda kwaizvozvi, rakajairika ari geji kuratidza kumanikidzwa rimwe chete jana Bourdon yechirimo. mhando kwakadaro dzinoshandiswa vachishingairira kuyera nevamwe kuwanda 0.6-1600 makirogiramu / masendimita ^2.

mvura-sa nevezera geji

Kusiyana kutsime, ari Urume nevamwe kumanikidza gauges kuyerwa vakadengezera uremu emura mbiru, sezvo nechiyero nevamwe iyi - ndiyo mvura pamwero iri nekufambisa midziyo. mano kwakadaro kubvumira kuyera nevamwe kuwanda 10-105 Pa, uye vari kushandiswa kunyanya murabhoritari.

Kutaura zvazviri, mumwe mudziyo yakadaro - a U-zvakaumbwa chubhu ine mvura ine wakakwirira chaiyo giravhiti kupfuura Urume zvakananga kuti hydrostatic kumanikidzwa kunoyerwa. Kazhinji, kwakadaro mvura iri nemekiyuri.

In muchikwata ichi inogona kunzi sananga rwevanhu hwokugadzira uye anodawo mano akadai TM-510 geji, TV-510, achimiririra muchikwata zvakumbirwa zvikuru. Vanoyera kwokudzvinyirira kwomunhu asiri crystallizable uye asiri nehasha vapor uye magasi. Kirasi rakarurama dzvinyiriro gauges: 1, 2.5, 1.5. Kushandisirwa boilers kwakadaro kudziyisa mugadziriro, kana kutakura mvura, uye maindasitiri kwendangariro.

Electric kuonana nevezera gauges

chikamu ichi zvinosanganisira kusanganisira Vacuum gauges uye manometers. Vari zvarakanyorerwa kuyera kumanikidzwa zvinwiwa uye magasi kuti kwandakarerekera panyaya simbi uye ndarira. Magadzirirwo mano aya akafanana kutsime, asi musiyano nhema chete iri hombe geometric miganhu. Housing huru yemagetsi kuonana manometer kuti mano kuonana mapoka. Uyewo, mumwe mudziyo akadaro anogona pachena kuti akamanikidzwa inodzorwa ezvinhu kuburikidza mukuvhara / okutanga vokukurukura.

Nokuda inokosha yemagetsi kuonana mashandiro, iro rinoshandiswa pano, kuti chikwata inogona kushandiswa aramu mugadziriro. Kutaura zvazviri, munzvimbo iyi rinoshandiswawo.

chinokosha

chikamu ichi mano inoshandiswa mumaindasitiri siyana kuti kuyera kumanikidzwa magasi akadai amoniya, rehydrogen, okisijeni, acetylene, etc. Kazhinji, chaiyo nekuyera geji zvinogoneka chete mhando imwe negasi. Nokuti mumwe gasi manometer akadaro akaratidza mutsa, izvo zviri kuitirwa kuti kuyera kufurirwa. Uyewo Gauge pachake kupendwa ari ruvara rinoenderana noruvara gasi uyo mudziyo rakagadzirwa. The pakunzi mudziyo rinoshandawo imwe tsamba. Somuenzaniso, amoniya gauges nguva dzose mavara ari tsvuku, vari varehwa tsamba A uye ngura kuramba vari aurayiwe.

Kune vibration-uchapupu anokosha namano kuti ushande mumamiriro ezvinhu mukuru ambient dzvinyiriro pulsing uye kunyanya vibration. Kana mumamiriro ezvinhu akadaro vanoshandisa zvisingatomboiti kumanikidzwa geji, kwenguva refu haana kushumira nokuti giya nokukurumidza kukundikana. Huru yokuona vibration-geji - a chisimbiso uye ngura nemishonga simbi casing.

kutsikisa

Musiyano mukuru pakati izvi anoyera zita. Izvi mano nguva akayera kumanikidza wakanyorwa pamusoro chati, kuti gare gare anobvumira kuona girafu zvavaida shanduko mune imwe nguva penguva. mano kwakadaro zvinoshandiswa simba engineering maindasitiri nokuda nokuyerwa kugamuchirwa waivako mune dzisiri kungatikanganisa runyararo.

chikepe

Ava zvarakanyorerwa kuyera Vacuum kumanikidzwa magasi, vapor uye mvura (mafuta, Diesel, mvura). mano kwakadaro vane akakwirira unyoro-uchapupu, kuramba okunze zvinofurira uye vibrations. Sezvinoratidzwa nezita racho, zvinokwanisika kunzwisisa munda wavo kushanda - rwizi uye gungwa zvifambiso.

njanji

Kusiyana kwakajairika kumanikidzwa gauges inotaridza kumanikidzwa mutengo, njanji mano asina kuratidzwa, uye vatendeuki kumanikidza chiratidzo neimwe nzira (digitaalinen, pneumatic, etc.). Nokuti chinangwa ichi, nzira dzakasiyana-siyana dzinogona kushandiswa.

Kwakadaro kumanikidzwa transducers vari zvinowanzoshandiswa pakupfuura kuzvidzora, kushandisa michina, uye, pasinei kwayo zita zvakananga, vari kushandiswa muminda mafuta, zvemakemikari, uye renyukireya.

mhedziso

Pressure chipimo chinodiwa maindasitiri mazhinji, uye mumwe nomumwe wavo, pane chinokosha gauges pamwe nemamwe zvinhu. Panotova chinokosha bhuku kufurirwa gauges, izvo aida kuisa uye kushanda ari fanira vaongo- namano. Akachengetwa muna Rostekhnadzor.

Asi chero bhizimisi uye chero mhando mano aya akagadzirirwa kuyera kufurirwa chete. Zvino kuti munoziva kuyera ndedzipi mhando uye kunzwisisa kumanikidza chipimo musimboti.
