Nrog rau kev loj hlob sai hauv kev lag luam ntawm metallurgy, mining, tshuaj siv tsev, dej thiab hluav taws xob, thee, thiab lwm yam. Ntau yam thiab zoo yuav tsum tau rautxiv tsawb screenntau thiab ntau siab, yog li ntawd lub vibrating npo mus rau ib theem tshiab ntawm txoj kev loj hlob, kev siv cov kev tshuaj ntsuam xyuas machinery yog ua ntau thiab ntau zaus thiab nws kim heev, nyob rau hauv kev siv cov txiv tsawb screen tuaj yeem tsim txhua yam kev ua txhaum ntawm cov txheej txheem, txo cov khoom siv.
Tam sim no lubtxiv tsawb screentej zaum yuav tshwm sim nyob rau hauv cov txheej txheem ntawm kev khiav hauj lwm thiab kev daws teeb meem los ua cov ntsiab lus hauv qab no:
Qhov txhaum 1: Txiv tsawb sifting qeeb thiab tsis muaj txiaj ntsig
a, txiv tsawb npo lub thawv torsional vibration;
b, vibrating npo lub thawv plaub lub kaum sab xis qhov sib txawv yog qhov loj;
c, vibrating npo lub thawv lateral viav vias
Cov laj thawj tseem ceeb:
a, ntawm ob sab ntawm kev co lub cev muaj zog eccentric thaiv theem tsis sib haum;
b, plaub lub kaum sab xis txhawb nqa lub caij nplooj ntoo hlav sib txawv yog qhov loj;
Kev daws:
a, kho ob sab ntawm lub eccentric thaiv, kom nws yog kiag li symmetrical;
B, txuam rau lub caij nplooj ntoos hlav txhawb nqa, kom ob sab ntawm qhov tawv nqaij zoo ib yam.
Fault 2:Txiv tsawb screenlub thawv vibration tsis sib xws
Cov laj thawj tseem ceeb:
a, cov khoom thaiv;
b, sieve nyob rau hauv yoj load;
c, txhawb kev puas tsuaj rau lub caij nplooj ntoos hlav;
Kev daws:
a, tshem tawm cov khoom thaiv;
b, ua kom cov khoom noj tsis zoo;
c, hloov lub caij nplooj ntoos hlav puas
Fault 3: vibration motor bearing cua sov
Cov laj thawj tseem ceeb:
a, bearing roj tsis txaus;
b, bearing roj ntau;
c, bearing clearance tsawg dhau;
d, bearing puas
Kev daws:
a, sau cov kabmob nrog roj;
b, xyuas cov roj bearing;
c, hloov mus rau loj clearance bearing;
d, hloov cov kabmob
Fault 4: Cov suab nrov txawv txav los ntawm shaker
Cov laj thawj tseem ceeb:
a, kev puas tsuaj;
b, xoob bolts ntawm lub npov npo;
c, xoob nro ntawm npo mesh
Kev daws:
a, hloov cov kabmob;
b, zawm thiab ntxiv dag zog rau lub bolts xoob;
C, nruj qhov screen dua;
Fault 5: Screen puas
Cov laj thawj tseem ceeb:
a, roj hmab ncoo nyob rau hauv qhov screen puas lawm;
b, lub vijtsam tsis nruj;
Kev daws:
a, hloov lub ncoo;
b, nruj qhov screen;
Fault 6: Sieve nres
Qhov laj thawj tseem ceeb: Cov khoom siv hluav taws xob tsis raug
Kev daws: Txheeb xyuas cov khoom siv hluav taws xob thiab kev co lub cev muaj zog.
