Phase<\/strong> opisuje vremensku vezu izme\u0111u dva signala ili, korisnije u radu s rotacijskim strojevima, vremensku vezu vibration<\/a> signala u odnosu na fiksnu referentnu oznaku na rotiraju\u0107em vratilu. Odgovara na pitanje where<\/em> in the rotation the vibration is happening, and it is normally measured in degrees from 0\u00b0 to 360\u00b0, one full revolution of the shaft. If amplitude<\/a> tells you how much<\/em> stroj vibrira i frequency<\/a> tells you how fast<\/em>, faza vam govori kako se kre\u0107e<\/em> \u2014 \u0161to je upravo ono \u0161to razdvaja kvarove koji dijele istu frekvenciju.<\/p>\n

Taj posljednji to\u010dka je sr\u017e za\u0161to je faza va\u017ena. Unbalance<\/a>, misalignment<\/a>, a bent shaft<\/a> and looseness<\/a> sve mogu podi\u0107i vrh od 1\u00d7 running-speed<\/a> vrh; faza je \u010desto jedini na\u010din da ih razlikujete bez demonta\u017ee stroja.<\/p>\n

1. Kako se mjeri faza<\/h2>\n

Potrebna su dva signala za \u010ditanje faze:<\/p>\n

    \n
  1. Signal vibracija<\/strong> \u2014 primarna mjerenja od accelerometer<\/a> ili sondu blizine<\/a> nadziranja kretanja ma\u0161ine.<\/li>\n
  2. Referentni signal<\/strong> \u2014 impuls vremenskog sinhroniziranja jednom po obrtu od tachometer<\/a>, usmjeren na traku od reflektivne trake<\/a> ili klju\u010dni \u017elijeb, tako da daje \u010dist impuls svaki put kada oznaka pro\u0111e senzor. Funkcionalno, to je ista uloga koju ima trajno instaliran Keyphasor<\/a>.<\/li>\n<\/ol>\n

    The analizatoru vibracija<\/a> then measures the time delay between the reference pulse and the first positive peak of the vibration signal at a chosen frequency \u2014 usually 1\u00d7 running speed \u2014 and converts that delay into an angle. A reading of 90\u00b0, for instance, means the vibration peak arrives one-quarter of a revolution after the reference mark passes the tachometer. Because the result is tied to a specific frequency, phase is most often quoted alongside the 1\u00d7 component; the same idea, generalised across the spectrum, is what makes the phase angle<\/a> sastavni dio dijagrama, kao \u0161to je Bode<\/a> and Nyquist<\/a> diagrams.<\/p>\n

    2. Dijagnosti\u010dka mo\u0107 faze<\/h2>\n

    Faza je mnogo vi\u0161e od broja. Uspore\u0111ivanjem mjerenja snimljenih na razli\u010ditim to\u010dkama ma\u0161ine, u istom smjeru mjerenja, analiti\u010dar mo\u017ee potvrdi ili isklju\u010di specifi\u010dne dijagnoze s velikom pouzdano\u0161\u0107u. Ponavljaju\u0107i motiv je usporedba dviju lokacija: ako se gibaju together<\/em> slika pokazuje jednu stranu; ako se gibaju u opposition<\/em> pokazuje na drugu. Odjeljci u nastavku pokrivaju klasi\u010dne obrasce.<\/p>\n

    Potvrda neuravnote\u017eenosti<\/h3>\n

    Pure unbalance gives similar phase readings \u2014 typically within about \u00b130\u00b0 \u2014 when measured in the same radial direction (say, horizontal) at both bearings of a rotor. The whole rotor is being pulled in one direction at one instant by the heavy spot, so the two ends march in step. Comparing horizontal and vertical readings at one bearing adds another clue: genuine unbalance tends to show a roughly 90\u00b0 difference between them.<\/p>\n

    Dijagnostikovanje neporavnjanosti<\/h3>\n

    Faza je jedan od najefikasnijih na\u010dina za potvrdu neuravnote\u017eenosti vratila misalignment<\/a>. Uzmi mjerenja faze u aksijalnom smjeru s obje strane coupling<\/a>: a 180\u00b0 phase shift (\u00b130\u00b0) across it is the textbook signature of angular misalignment, showing that as one shaft moves axially out, the other moves in \u2014 a pivoting, see-saw motion at the coupling.<\/p>\n

    Razlikovanje neuravnote\u017eenosti od savijenog vratila<\/h3>\n

    Neuravnote\u017eenost i bent shaft<\/a> raise 1\u00d7 vibration, yet phase tells them apart. Axial phase readings taken at the two ends of the same motor or pump shaft that differ by about 180\u00b0 indicate a bow: the ends move in opposite axial directions as the bend rotates.<\/p>\n

    Prepoznavanje dosjeda ili pukotine na temelju<\/h3>\n

    Kada su mjerenja faze nepravilna, nestabilna ili neponavljiva, mehani\u010dka looseness<\/a> je uobi\u010dajeni \u0161umac. Markantna promjena faze kako se sonda premje\u0161ta sa noge ma\u0161ine na njenu osnovicu, ili sa osnovice na temelj, pokazuje na labavog sidrnog vijka ili puknutog temelja \u2014 i ukazuje na neadekvatnu krutost temelja<\/a>.<\/p>\n

    Potvrda rezonancije<\/h3>\n

    Kako se ma\u0161ina pokre\u0107e ili klizi kroz critical speed<\/a>, the 1\u00d7 phase makes a characteristic 90\u00b0 shift exactly at the resonance<\/a> vr\u0161nu to\u010dku i potpuni 180\u00b0 pomak kroz cijelo podru\u010dje rezonancije. Pa\u017eljivo pra\u0107enje te promjene \u2014 lako zabilje\u017eeno tijekom coastdown<\/a> \u2014 je odre\u0111uju\u0107i na\u010din za potvrdu rezonancije umjesto problema forsiranja.<\/p>\n

    3. Brz pregled za obrasce faze<\/h2>\n\n\n\n\n\n\n\n
    Observation<\/th>\nVjerovatna dijagnoza<\/th>\n<\/tr>\n

    Ova pravila su vodi\u010di, ne jamstva: potvrdite sa amplitudom, oblikom spektra i harmonic<\/a> sadr\u017eajem prije nego se opredijelite za popravku.<\/p>\n

    4. Faza kao klju\u010d za balansiranje<\/h2>\n

    Faza je neophodna za balansiranje rotora<\/a>. O\u010ditavanje faze 1\u00d7 direktno pokazuje na kutni polo\u017eaj te\u0161ke to\u010dke u odnosu na referentnu oznaku, javljaju\u0107i tehni\u010daru to\u010dno gdje dodati ili ukloniti mase korekcije<\/a>. U praksi analizator bilje\u017ei amplitudu i fazu prije nego se trial weight<\/a> montira, ponovno nakon toga, i koristi promjenu za izra\u010dun koeficijenti utjecaja<\/a> koji daju kona\u010dnu korekciju. Prijenosni dvokanalski instrument kao \u0161to je Balanset-1A<\/a> izvr\u0161ava ovo mjerenje amplitude i faze u le\u017eajima same ma\u0161ine pri brzini rada, zatim provjerava rezidualnu neuravnote\u017eenost<\/a> nakon \u0161to su te\u017eine na mjestu. Za rad sa kutnom podjelom kada korekcija mora biti distribuirana izme\u0111u te\u017eina, na\u0161a Kalkulator kuta faze vibracije<\/a> \u0440\u0443\u043a\u043e\u0432\u043e\u0434\u0438 vektorskom geometrijom.<\/p>\n

    5. Za\u0161to Faza Dovr\u0161ava Sliku<\/h2>\n

    Bez faze, analiti\u010dar vibracija vidi samo dio pri\u010de \u2014 magnitude i frekvencije, ali nema razumijevanja kako struktura zapravo deformira kroz svaki okret. Faza pru\u017ea taj nedostaju\u0107i kontekst, pretvaraju\u0107i popis vrhova u jasnu izjavu o kretanju i dramati\u010dno podi\u017ee povjerenje u dijagnostiku. To je razlika izme\u0111u znanja da ma\u0161ina vibrira i znanja za\u0161to. Iz tog razloga, faza pripada svakoj ozbiljnoj dijagnozi i predstavlja neophodan temelj terenskog balansiranje<\/a>.<\/p>\n
