Isilinganiso se-voltage tester
Umdwebo we-Operation Block:
Umhloli wamanje wokuvuza olawulwa wohlelo ovumelanisa ne-voltage Checker yakhiwa umjikelezo omkhulu we-voltage I-High-Voltage Boost Palcuit ingaguqula umphumela wokuphuma okudingekayo, kanye nesekethe yokutholwa kwamanje edingekayo ingasetha ukuqhekeka (ukuvikela) okwamanje, iyalela indawo yokuhlola i-Voltage Vertage nenani lamanje (noma setha inani lamanje lokuvuza ). Lapho isampula lifinyelela isikhathi esidingekayo ngaphansi kwamandla kagesi adingekayo, ithuluzi lizophoqeleka noma liphoqelelwe ukuvimba amavolumu wokuhlola; Lapho ukwephuka kwenzeka, ukuvuza kwamanje kudlula ukuphelelwa phansi okusethiwe (ukuvikela) kwamanje, kuzovinjwa i-voltage kagesi ngasikhathi sinye, ukuze kukhishwe i-alamu ngasikhathi sinye, ukuze i-alamu izokwamukela ukuthi ngabe isampula ingakwamukela yini ukuhlolwa kwamandla ajwayelekile kwe-dielectric .
Umhloli we-Voltage Voltage uyithuluzi eliyisisekelo lokulinganisa ukuphakamisa amandla kagesi. Kungahlose ngokunembile, ngokunembile, ngokushesha nangokwethembekile uhlole i-voltage ye-breakdown, ukuvuza kwamanje nezinye izinkomba zokuphepha zikagesi zokuphepha kwezinto ezihloliwe ezahlukahlukene, futhi zingasetshenziswa njenge-ac (ngqo) umthombo ophakeme we-ac (ngokuqondile) ukubheka izakhi nemisebenzi ye Wonke umshini. Uchungechunge lomkhiqizo wokuhlola we-volstage luhlelwe ngokuya ngemithetho yezokuphepha yamazwe omhlaba njenge-IEC, i-ISO, BS, i-Ul, JIS, njll. Izidingo ezikhethekile zinqunywa ngokwahlukana. Ilungele izinto ezahlukene zasendlini, izinsiza zamandla, amakhebuli, ama-transformers, amabhlogo we-terminage bakelite, motor, amathuluzi we-elektroniki, indawo, imishini ephelele, kanye nokuhlolwa kwe-hastandle ephephile Amandla kagesi kanye nokuvuza kwamanje kohlelo oluqinile lwamanje, futhi luyimishini yokuhlola ingcindezi ebaluleke kakhulu yama-laboratories kanye neminyango yezobuchwepheshe.
Imikhiqizo yochungechunge lwengcindezi yengcindezelo isuselwa ekuhlolweni nasekugayweni kwabahloli bengcindezi yakwamanye amazwe, kuhlanganiswe nokusetshenziswa okusebenzayo kwabasebenzisi abaningi baseChina ukuze bathuthukise futhi bathuthukise. Umhloli we-Voltage Voltage uchungechunge lwe-Digital Display Display ebekezelela abahloli beVoltage. I-voltage yokuhlola, ukuvuza kwamanje, nesikhathi sokuhlola konke kukhanya kwedijithali. Ukuvuza kwamanje kungasetwa ngokunqumela ngokuya ngemithetho ehlukene yokuphepha kanye nezidingo ezahlukahlukene zabasebenzisi. Kukhona i-Countdown Digital Flashing ngesikhathi sokulinganisa, esenza ukunemba kwesikhathi sokuhlola kusenesikhathi ngaphezu kwe- ± 1%, futhi uhlelo lokuhlola luthuthukela kuma-99s, umsebenzi ugcwele futhi luwusizo Ngokuya ngemisebenzi yezobuchwepheshe kanye nokwethenjwa kwekhwalithi.
Izici nokusetshenziswa okuhlukile kwe-vibrometer
I-vibrometer ibizwa nangokuthi i-vibrate analyzer noma ipeni le-vibrometer. Umgomo we-vibrometer yakhelwe ngokusebenzisa i-piezoelectric umphumela we-quartz crystal kanye ne-cerarics ngobuciko. Ngokuvamile khetha isakhiwo sePiezoelectric ukusebenza.
Umhloli wamanje wokuvuza wohlelo aklanyelwe nge-polarized ceraric piezoelectric umphumela. Inomsebenzi wokunquma ubukhulu (ijubane) etafuleni le-oscillation, futhi futhi inomsebenzi wokunquma ngokuqondile iziphambeko zama-bearings nama-gearbox, futhi inokucaciswa okucacile kokuthola ama-gear. , Isetshenziselwa ukukalwa kwe-periotion motion ukuthola ukungalingani kanye nokwephulwa kwemishini yokunyakaza. I-vibrometer isebenzisa i-accelerometer ephezulu yomsebenzi wokuqedela izilinganiso ezinembile neziphindaphindwayo. Imitha yokudlidliza ilungele ukukalwa kwe-oscillation ejwayelekile yemishini yemishini, futhi ingalinganisa ukufuduka kwe-oscillation, velocity kanye nokusheshisa. Isetshenziswa kabanzi ekukhiqizeni imishini, izimoto zikagesi, izimoto, okujwayelekile kwe-aerospace kanye nezinye izinkambu.
Imitha yokudlidliza ifakwe enhlanganweni yokuphatha imishini. Ngokohlobo lomsebenzi kanye nokwahlukana kwabasebenzi, kunikezwe amamitha ahlukahlukene. UMnyango Wezamandla uhlome ngohlelo lokuhlaziya lweRion yaseJapan, futhi unohlelo lokuxilonga lwedatha yokuqoqa idatha. Ipharamitha yokulinganisa ukushesha. , Isivinini, ukuthutha, izinga lokushisa, isivinini sokujikeleza. Kwabahloli begatsha, i-Oscillator ephathekayo ephathekayo ephathekayo efakwe ngamapharamitha wokulinganisa anjengokusheshisa, isivinini, ukuthukuthela, njll., Okulungele ukuhloba okungahleliwe kokusebenza kwemishini. Abasebenzi bokuhlola kanye nokulungiswa ababona amapharamitha ayisisekelo angafakelwa ngochungechunge ophathwayo lwamamitha okudlidliza, alungele ukuhlola yonke imishini, ijubane, kanye nokusuka kwayo yonke imishini yemishini efana nama-motors, amaphampu, abalandeli kanye nabacindezeli.
Indlela yokulinganisa imitha yokulinganisa kanye nesisekelo sokwahlulela
1. Ukukhetha amaphoyinti wokulinganisa amamitha wokudlidliza: Sebenzisa imitha yokudlidliza ukuze uhlole ama-bearings kanye namaphuzu wokugcina we-axial wemishini eyinhloko, futhi uhlome ngetafula lokuqoshwa kwe-in-site. Iphuzu ngalinye lokulinganisa kufanele lihambisane.
2. Ukulinganisa umjikelezo we-vibrometer: Kudingeka ukuthi ihlolwe njalo emavikini amabili ngemuva nje kokufakwa kwemishini noma eduze kwe-averhel; Kuhlolwa kanye ngenyanga ngesikhathi sokusebenza okujwayelekile; Uma kunoshintsho olubalulekile phakathi kwenani elinganisiwe nenani lokugcina elinganisiwe, ukuhlolwa kufanele kuqiniswe usizi, ukuze kuvinjelwe izingozi ezingalindelekile futhi kwakha ukuvala okungonakele.
3. Isisekelo sokunquma inani elilinganisiwe le-vibrometer: bhekisa ku-International Standard Iso2372.
Isivinini sokujikeleza: 600 ~ 1200r / min, uhlelo lokulinganisa lwe-oscillation: 10 ~ 1000hz.
Imvamisa, lapho imishini isebenza okujwayelekile, inani lejubane layo lokutholwa ngu-4.5 ~ 11.2mm / s (amayunithi angenhla kwama-75kw) kuhlelwa ukuqapha kanye nesicelo. Uma idlula 7.1mm / s, kuyadingeka ukubheka ukuhlela ukulungiswa okukhulu. Ukuqinisekisa leli nani, ngaphezu kokubheka amandla e-motor esetshenziswayo, kufanele futhi ucabangele izici zokuqhubeka okuqhubekayo kokusebenza, ukuphepha, ukwethenjwa kanye nokuphela okuphezulu.
