Along with the rapid development in the industries of metallurgy, mining, chemical building materials, water and electricity, coal,etc. Variety and quality requirements for banana screen more and more high, so that the vibrating screen to a new stage of development, the use of comprehensive screening machinery is becoming more and more frequent and extensive, in the use of the banana screen can produce all kinds of faults in the process, reduce production efficiency.
Now the banana screen may occur in the process of operation and troubleshooting methods to make the following summary:
Fault 1:Banana sifting is slow and inefficient
a, banana screen box torsional vibration;
b, vibrating screen box four Angle amplitude difference is large;
c, vibrating screen box lateral swing
Main reasons:
a, on both sides of the vibration motor eccentric block phase is inconsistent;
b, four Angle support spring stiffness difference is large;
Solution:
a, adjust the two sides of the eccentric block,so that it is completely symmetric;
B, matching the supporting spring, so that both sides of the stiffness is consistent.
Fault 2: Banana screen box vibration is not uniform
Main reasons:
a, material blockage；
b, sieve under wave load；
c, support spring damage；
Solution:
a, remove material blockage；
b, make the material uniform feeding；
c, replace the damaged spring
Fault 3: vibration motor bearing heating
Main reasons:
a, bearing oil shortage；
b, bearing oil much;
c, bearing clearance is too small;
d, bearing damage
Solution:
a, fill the bearing with oil;
b, check the bearing oil amount;
c, switch to large clearance bearing;
d, replace the bearing
Fault 4: Abnormal noise from shaker
Main reasons:
a, bearing damage;
b, loose bolts of screen box;
c, loose tension of screen mesh
Solution:
a, replace the bearing;
b, tighten and reinforce the loose bolt;
C, tighten the screen again;
Fault 5: Screen damage
Main reasons:
a, the rubber pad under the screen is damaged;
b, the screen is not tight;
Solution:
a, replace the pad;
b, tighten the screen;
Fault 6: Sieve stop
Main cause: The power supply is faulty
Solution: Check the power supply and vibration motor lead .
