Roots blower vibration main reasons: (1) Roots blower wheel vibration caused by unbalanced cheap itself, its causes are: parts of the impeller loose change, uneven deformation or corrosion, wear; working medium of solid particles deposited on the rotor; uneven overhaul replacement parts new weight; impeller manufactured material is not absolute symmetry; precision error, equipped with a deviation. (2) the impeller and the shaft with the gap is too large. (3) Spindle bent. (4) a rigid foundation or base is not strong enough or basic steel weak, loose horn, displacement; bolt loosening. (5) base sink, tilt or cracks. (6) units installed level is not good, there is a change of rotor deflection. (7) the coupling center caused due to poor installation alignment error is too large. With the gap (8) coupling and shaft is too large; elastic sleeve gap is too large or uneven gaps. (9) the phenomenon of friction noise control with blower impeller skew collide with the inner wall of the housing within the cabinet. (10) the current collector and the gap between the fan impeller blower uneven none other sales, or friction phenomenon. (11) bearing wear, the gap is too large; journal wear, bearing sleeve and the journal with the gap bigger. (12) transporting the media channel is blocked, rust, dirt. (13) the fan inlet pipe, outlet pipe installation poor. (14) connected to various parts of the loose bolts. Air volume is less than 1, 2 filter clogging, a gap increases, replace or clean the filter 2, to take appropriate measures blower, repair a gap motor overload, filter clogging 2, 3 fan boost is too large, the impeller impeller, rubbing a wall or cabinet, replace or clean the filter 2, identify the reasons for the boost limit raised to three, repair friction surface. Re-adjust the gap none other sales Roots blower | Shantou blower | three cattle machinery provided by three cattle Machinery Co., Ltd., Shandong. Machinery Co., Ltd.
