Faza<\/strong> opisuje vremensku vezu izme\u0111u dva signala ili, \u0161to je korisnije u radu na rotiraju\u0107im strojevima, vrijeme vibracija<\/a> signala u odnosu na fiksnu referentnu oznaku na rotiraju\u0107oj osovini. Odgovara na pitanje Gdje<\/em> u kojem se dijelu okreta vibracija doga\u0111a, i obi\u010dno se mjeri u stupnjevima od 0\u00b0 do 360\u00b0, jedan puni okretaj vratila. Ako amplituda<\/a> vam govori koliko<\/em> stroj vibrira i frekvencija<\/a> vam govori koliko brzo<\/em>, faza vam pokazuje kako se kre\u0107e<\/em> \u2014 \u0161to je upravo ono \u0161to razlikuje gre\u0161ke koje dijele istu frekvenciju.<\/p>\n

Posljednja to\u010dka je sr\u017e za\u0161to je faza va\u017ena. Neravnote\u017ea<\/a>, neuskla\u0111enost<\/a>, a iskrivljeni vrat<\/a> i labavost<\/a> mogu svi podi\u0107i 1\u00d7 brzina tr\u010danja<\/a> vrh; faza je \u010desto jedini na\u010din da ih razlikujete bez rastavljanja stroja.<\/p>\n

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

Dva signala su potrebna za \u010ditanje faze:<\/p>\n

    \n
  1. Signal vibracija<\/strong> \u2014 primarno mjerenje od akcelerometar<\/a> ili sonda za blizinu<\/a> promatranja gibanja stroja.<\/li>\n
  2. Referentni signal<\/strong> \u2014 puls vremenskog okidanja jedan put po revoluciji od tahometar<\/a>, usmjeren na traku od reflektiraju\u0107a traka<\/a> ili na \u017elijeb tako da puceta \u010dist puls svaki put kada oznaka pro\u0111e senzor. Funkcionalno to je ista uloga koju igra trajno instaliran Keyphasor<\/a>.<\/li>\n<\/ol>\n

    The analizator vibracija<\/a> zatim mjeri vremensko ka\u0161njenje izme\u0111u referentnog impulsa i prvog pozitivnog vrha vibracijskog signala na odabranoj frekvenciji \u2014 obi\u010dno 1\u00d7 radna brzina \u2014 i pretvara to ka\u0161njenje u kut. O\u010ditanje od 90\u00b0, primjerice, zna\u010di da vrh vibracije sti\u017ee jednu \u010detvrtinu okretaja nakon \u0161to referentna oznaka pro\u0111e tahometar. Budu\u0107i da je rezultat vezan uz odre\u0111enu frekvenciju, faza se naj\u010de\u0161\u0107e navodi uz komponentu 1\u00d7; ista ideja, poop\u0107ena kroz spektar, ono je \u0161to omogu\u0107uje fazni kut<\/a> gradbeni element prikaza kao \u0161to je Bode<\/a> i Najkvist<\/a> dijagrami.<\/p>\n

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

    Faza je daleko vi\u0161e od broja. Usporedbom o\u010ditanja snimljenih na razli\u010ditim to\u010dkama na stroju, u istom smjeru mjerenja, analiti\u010dar mo\u017ee potvrditi ili isklju\u010diti specifi\u010dne dijagnoze s visokom sigurnosti. Ponavljaju\u0107i se motiv je usporedba dvaju mjesta: ako se kre\u0107u zajedno<\/em> slika pokazuje na jedan na\u010din; ako se kre\u0107u u opreka<\/em> to pokazuje na drugi. Odjeljci ispod pokrivaju klasi\u010dne obrasce.<\/p>\n

    Potvr\u0111ivanje neuravnote\u017eenosti<\/h3>\n

    \u010cista neuravnote\u017eenost daje sli\u010dna o\u010ditanja faze \u2014 tipi\u010dno unutar oko \u00b130\u00b0 \u2014 kada se mjeri u istom radijalnom smjeru (recimo vodoravno) na oba le\u017eaja rotora. Cijeli rotor u jednom trenutku vu\u010de se u jednom smjeru zbog te\u0161ke to\u010dke, pa oba kraja idu u korak. Usporedba vodoravnih i okomitih o\u010ditanja na jednom le\u017eaju daje jo\u0161 jedan trag: stvarna neuravnote\u017eenost obi\u010dno pokazuje pribli\u017eno 90\u00b0 razlike izme\u0111u njih.<\/p>\n

    Dijagnosticiranje neuskla\u0111enosti<\/h3>\n

    Faza je jedan od najefikasnijih na\u010dina za potvrdu neravnote\u017ee vratila neuskla\u0111enost<\/a>. Uzmite aksijalne fazne o\u010ditine sa obje strane spojka<\/a>: fazni pomak od 180\u00b0 (\u00b130\u00b0) preko nje \u0161kolski je primjer kutnog neporavnanja, pokazuju\u0107i da dok jedno vratilo aksijalno izlazi, drugo ulazi \u2014 njihaju\u0107e gibanje poput klackalice na spojci.<\/p>\n

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

    I neubalansiranjenost i iskrivljeni vrat<\/a> podi\u017eu vibraciju 1\u00d7, ali faza ih razlikuje. Aksijalna o\u010ditanja faze uzeta na dva kraja istog vratila motora ili pumpe koja se razlikuju za oko 180\u00b0 ukazuju na savijanje: krajevi se pomi\u010du u suprotnim aksijalnim smjerovima dok se savijanje okre\u0107e.<\/p>\n

    Identificiranje neusidrenosti ili napuklnog temelja<\/h3>\n

    Kad su o\u010ditanja faze nasumi\u010dna, nestabilna ili neponovljiva, mehani\u010dka labavost<\/a> je uobi\u010dajeni uzrok. Ozna\u010dena promjena faze dok se sonda premje\u0161ta s noge stroja na njegovu baznu plo\u010du, ili s bazne plo\u010de na temelj, ukazuje na ohlabljeni klinast \u010davao ili napuklni temelj \u2014 i nagovje\u0161tava nedostatnu krutost temelja<\/a>.<\/p>\n

    Potvr\u0111ivanje rezonancije<\/h3>\n

    Dok se stroj pokre\u0107e ili ko\u010di kroz kriti\u010dna brzina<\/a>, faza 1\u00d7 karakteristi\u010dno se pomakne za 90\u00b0 to\u010dno na rezonancija<\/a> vrh i potpuni pomak od 180\u00b0 preko cijelog podru\u010dja rezonancije. Promatranje tog pomaka \u2014 lako zabilje\u017eenog tijekom obala<\/a> \u2014 je definitivna metoda za potvrdu rezonancije umjesto problema sile.<\/p>\n

    3. Brz pregled za obrasce faze<\/h2>\n\n\n\n\n\n\n\n
    Promatranje<\/th>\nVjerojatna dijagnoza<\/th>\n<\/tr>\n
    Oba le\u017eaja u fazi, ista radijalna smjer<\/td>\nNeravnote\u017ea<\/td>\n<\/tr>\n
    \u2248180\u00b0 preko spojke, aksijalno<\/td>\nKutna neuskla\u0111enost<\/td>\n<\/tr>\n

    Ova pravila su vodi\u010di, ne jamstva: potvrdi s amplitudom, oblikom spektra i harmonik<\/a> sadr\u017eajem prije nego \u0161to se da\u0161 u popravak.<\/p>\n

    4. Faza kao klju\u010d za uravnote\u017eavanje<\/h2>\n

    Faza je neophodna za Balansiranje rotora<\/a>. O\u010ditanje faze 1\u00d7 pokazuje direktno na kutnu lokaciju te\u0161ke to\u010dke u odnosu na referentnu oznaku, govore\u0107i tehnu\u0161aru to\u010dno gdje dodati ili ukloniti korekcijska te\u017eina<\/a>. U praksi analizator bilje\u017ei amplitudu i fazu prije probna te\u017eina<\/a> je instaliran, ponovno zatim, i koristi promjenu za izra\u010dunavanje koeficijenti utjecaja<\/a> koji daju kona\u010dnu korekciju. Prijenosni dvokanalski instrument poput Balanset-1A<\/a> izvr\u0161ava ovo mjerenje amplitude i faze u le\u017eajima samog stroja pri radnoj brzini, zatim provjerava preostala neravnote\u017ea<\/a> nakon \u0161to su utezi na mjestu. Za odre\u0111ivanje kutnog raspodjele kada korekcija mora biti podijeljena izme\u0111u utega, na\u0161 Kalkulator kuta faze vibracije<\/a> rje\u0161ava vektorsku geometriju.<\/p>\n

    5. Za\u0161to faza \u010dini sliku potpunom<\/h2>\n

    Bez faze, analiti\u010dar vibracija vidi samo dio pri\u010de \u2014 magnitude i frekvencije, ali nema uvida kako se struktura zapravo deformira kroz svaki okret. Faza pru\u017ea taj nedostaju\u0107i kontekst, pretvaraju\u0107i niz vrhova u jasnu izjavu o gibanju i dramati\u010dno pove\u0107avaju\u0107i povjerenje u dijagnostiku. To je razlika izme\u0111u znanja da stroj vibrira i znanja za\u0161to. Iz tog razloga, faza pripada svakoj ozbiljnoj dijagnostici i temelj je koji se ne mo\u017ee izbjegavati na terenu balansiranje<\/a>.<\/p>\n
