Air screen bearing common fault with routine maintenance matters

 First, the flow of imports sieve method to deal with the phenomenon of bearing cards injury
A slide bearing NSK air screen appears cards injury phenomenon causes : too much load, excessive preload . Poor lubrication . Foreign body bite . Tilt, inner outer shaft

deflection . Poor precision shaft , screen flow bearing housing .
2 air screen bearing state phenomenon occurs card hurt performance : the so-called card surface damage due to Mobile crushing plant the injury is minor burns part of NSK Bearings screen flow

generated in the sliding surface injury arising summarized .
Approach 3 NSK Bearings airflow sieve injury occurs card phenomenon : Check the load size. Preload should be appropriate. Improving lubricant and lubrication methods. Check

shaft , screen flow bearing box accuracy.

Second, the air flow sieve common mobile screening plant fault analysis and solution
1, when a sudden increase in the amount taken when handling product testing analysis, if the finished product failed , check the screen is intact.
2 , when the material suddenly not working .
( 1 ) should check whether the fan is normal, if the fan flow reduction, should overhaul fan.
( 2) Check whether the discharge outlet can not rotate , you can not discharge .
3 , when the capacity is mainly the application of screening tests to detect the material meets the screening requirements.
Third, the air flow sieve daily Cautions :
1 , the same type of air screening machine, the greater the corresponding mesh screening material yield.
2 , screen flow screening should have a viscosity , water content greater than 5 % of the materials and flammable and explosive materials.
