Mhando nemitemo yekushandisa pendi ukobvu gaji

Kana uchitenga mota yakamboshandiswa, zvinogona kuomera mutengi kunyatsoongorora mamiriro ayo. Kuseri kweye yakanaka kuputira kunogona kuviga zvakakomba zvakakanganisika uye kukuvara kunokonzerwa nenjodzi, iyo mutengesi anogona kunge akanyarara nezvayo. Chinhu chakakosha - ukobvu geji - chinobatsira kuburitsa hunyengeri, kuongorora mamiriro chaiwo emuviri uye kuona kuwanda kwependi yayo.

Chii chinonzi ukobvu geji

Ukobvu hwependi (hwekupenda) hunoyerwa mumamirioni (chiuru chemamirioni = 1 mm.). Kuti unzwisise zviri nani izvi zvakawanda, fungidzira bvudzi remunhu. Hurefu hwepakati pawo makumi mana emamirioni, uye ukobvu hweA000 sheet ndeye 1 microns.

Iyo ukobvu geji inoyera chinhambwe kubva pasimbi kusvika kugeji uchishandisa magetsi emagetsi kana emagetsi mafungu. Iyo kifaa inoona iyo wavelength uye inoratidza mhedzisiro pachiratidziro.

Nekudaro, zvinokwanisika kuona iyo yakapendwa uye yeplate zvikamu mushure mekugadziriswa, uchiziva ukobvu hwependi yemumwe muenzaniso. Ivhareji kukosha kwemota dzemazuvano iri mumatanho e90-160 microns. Iko kukanganisa kunotenderwa munzvimbo dzakasiyana dzemuviri nemakumi matatu nemakumi mana emamirioni, kukanganisa kwechigadzirwa pachako kunofanira kutarisirwa.

Mitauro yemashandisirwo

Kune huwandu hukuru hwemhando dzejiji dzehurefu. Kune akasiyana mamodheru ekuyera ukobvu hwekongiri, bepa, yakatetepa machubhu kana machira. Mhando ina huru dzinoshandiswa kuyera pendi:

• magnetic;
• remagetsi;
• ultrasonic;
• eddy yazvino.

Magnetic

Midziyo yakadaro ine dhizaini yakapusa. Iko kune magineti mune diki kesi. Zvichienderana neukobvu hwekupfeka, simba rinokwezva remagineti richachinja. Mhedzisiro yakawanikwa inoendeswa kumuseve, iyo inoratidza kukosha muma microns.

Magnetic ukobvu mageji haadhuri, asi iwo akaderera mukuyera kurongeka. Inotaridza chete hunhu hwekufungidzira uye inongoshanda nesimbi nzvimbo. Mutengo wechigadzirwa unogona kutanga kubva ku400 rubles.

Remagetsi

Iyo yemagetsi ukobvu geji rinoshanda nenzira yakafanana kune yemagineti ukobvu gauge, asi inoshandisa electromagnetic induction yezviyero. Kururamisa kwemamita akadaro kwakakwirira, uye mutengo unogamuchirwa, anenge zviuru zvitatu zveRubles. Naizvozvo, izvi zvishandiso zvinowanzoitika pakati pevatyairi. Kukanganisa kwavo kukuru ndekwekuti ivo vanokwanisa chete kushanda nesimbi nzvimbo. Ivo havayeri kupfeka pane aluminium kana mhangura zvikamu.

Ultrasonic

Iwo musimboti wekushanda kweaya makobvu mageji akavakirwa pakuyera kumhanya kwekufamba kwema ultrasonic mafungu kubva kumusoro kusvika kune sensor. Sezvaunoziva, ultrasound inopfuura nepakati pezvinhu zvakasiyana nenzira dzakasiyana, asi ichi ndicho chikonzero chekuwana data. Ivo vanoita zvakasiyana-siyana nekuti vanogona kuyera ukobvu hwependi pamhando dzakasiyana siyana, kusanganisira mapurasitiki, zvedongo, zvinoumbwa nesimbi. Naizvozvo, zvishandiso zvakadaro zvinoshandiswa panzvimbo dzevashandi dzehunyanzvi. Iko kusakosha kweiyo ultrasonic ukobvu gauges ndiyo yavo yakakwira mutengo. Paavhareji, kubva kuzviuru gumi zvemabhuru uye nezvimwe.

Eddy iyezvino

Rudzi urwu rwehuremu hwegeji ine yakanyanya kuyerwa kurongeka. Kuyerwa kweLKP kunogona kuitiswa pane chero simbi pamusoro, pamwe nesimbi isiri feri (aluminium, mhangura). Kururamisa kunoenderana nekutungamira kwezvinhu. An EM coil inoshandiswa, iyo inogadzira vortex magnetic minda pamusoro pesimbi. MuFizikiki, izvi zvinodaidzwa kuti Foucault currents. Zvinozivikanwa kuti mhangura nealuminium mufambiro wazvino zvirinani, zvinoreva kuti nzvimbo idzi dzinenge dziine kuverenga kwakanyanya kwazvo. Pachave nekukanganisa pane iyo Hardware, dzimwe nguva yakakosha. Iyo chishandiso chakaringana kuyerwa pane iyo aluminium muviri. Mari yepakati ndeye zviuru zvishanu zvemaruble uye nezvimwe.

Kuenzanisa chiridzwa

Chimbo chinofanira kunge chakaverengerwa usati washandiswa. Izvi zviri nyore kwazvo kuita. Pamwe chete nechigadzirwa, seti yacho inosanganisira mareferenzi mahwendefa akagadzirwa nesimbi uye plastiki. Chimbo chinowanzove ne "cal" (calibration) bhatani. Mushure mekudzvanya bhatani, iwe unofanirwa kusungira iyo ukobvu geji sensor kune ndiro yesimbi uye kuisazve zero. Takabva taisa imwe yepurasitiki mundiro yesimbi ndokuyera zvakare. Kukora kweplate repurasitiki kwakatonyorwa pairi. Semuyenzaniso, 120 microns. Inosara chete kutarisa mhedzisiro.

Zvidiki kutsauka kwema microns mashoma anotenderwa, asi izvi zviri mukati meyakajairika renji. Kana iyo kifaa ikaratidza kukosha kwakakodzera, ipapo unogona kutanga kuyera.

Mashandisiro ekushandisa iyo goji geji

Tsvaga iyo hukobvu hwefekitori yemotokari pendi usati wayera. Kune akawanda tafura yedhata paInternet. Zviyero zvinofanirwa kutanga kubva kumberi kwepapiro, zvishoma nezvishoma zvichifamba pamwe nekukomberedza kwemuviri. Kunyatso nyatso tarisa nzvimbo dzinokombamira kukukanganisa: vanodzivirira, madhoo, masills. Isa iyo sensor kune yakachena uye yakaenzana muviri pamusoro.

Kuverenga pamusoro pe300 µm kunoratidza kuvepo kwekuzadza uye kupenda. 1-000 microns inoratidza zvakakomba zvakakanganisika munzvimbo ino. Iyo yepamusoro yakatwasanudzwa, putty uye kupendwa. Mota inogona kunge yakaita tsaona yakakomba. Mushure mechinguva, kutsemuka uye machipisi zvinogona kuoneka panzvimbo ino, uye ngura ichatanga. Nokutsvaga nzvimbo dzakadaro, kukanganisa kwekare kunogona kuongororwa.

Izvi hazvireve kuti mota ine pendi yekugadzirisa haidi kutengwa. Semuenzaniso, kuverenga pamusoro pe200 µm kunowanzo kuratidza kubviswa kwezvikwambo uye madiki machipisi. Izvi hazvitsoropodzi, asi zvinogona kudzikisira mutengo. Iko kune mukana wekutaurirana.

Kana zviratidziro zvakadzikira zvakanyanya pane izvo zvefekitori, izvi zvinoratidza kuti tenzi akaipfuura nekukwenenzvera kwekukonzeresa pakubvisa kukwenya. Ndakabvisa dura rependi raive rakakora.

Iwe zvakare unofanirwa kunzwisisa kuti ndeupi rudzi rwechigadzirwa chauinacho mumaoko ako. Iyo yemagetsi ukobvu gauge haishande papurasitiki. Izvo hazvishande kuyera iyo pendi pane iyo bhamba. Iwe uchazoda chigadzirwa che ultrasonic. Iwe zvakare unofanirwa kuziva kana paine aruminiyamu zvikamu mumuviri.

Haufanire kutenga mudziyo mutsva kana usingaushandise kazhinji. Iyo ukobvu geji inogona kubhadharwa pamubhadharo.

Iyo ukobvu geji inokutendera iwe kuti uongorore mamiriro ekupenda kwemuviri wemota. Mhando dzakasiyana dzechiridzwa dzine chokwadi chakasiyana uye kugona. Kune zvavo zvavanoda, remagetsi rinokodzera. Kana iwe uchida kuongororwa kwakazara kwemuviri, saka unofanirwa kutaura nevashandi.
