Notes on the use of vibrating motor

  1. Horizontal vibration motor which does not install protective cover is not allowed to run;
  2. The electronic control system of vibration motor should has a reliable grounding device and protective device, such as lack of protection, over current protection, over heat protection, etc.;
  3. The vibration motor which is in the first use or has placed for a long time, the stator coil insulation should be measured with a 500V megger before used. The insulation resistance should not be less than10M, If not up to this value, then the motor must be done with the dry processing;motor
  4. Before the vibration motor being in operation, we must check the following items: If the installation of vibration motor and fastener is firm and reliable;  If connection of power cable of vibration motor is correct and strong; If the grounding and protection device of vibration motor is in place.
  5. We should pay attention to the running situation in the work frequently, if there is overheating, abnormal sound, serious leakage and other abnormal conditions, it should be checked and processed in a timely manner;
  6. Carefully read the instructions for use before using the vibration motor.

Adjustment method for exciting force of horizontal vibration motor is too small

Excitation force of the vibration motor is too small is the problem that the drilling fluid vibration screen users often encounter, then how to solve the problem? In fact, the exciting force of vibration motor was adjusted to 80% when came out of the factory, and was adjusted to to 0% when required shipping (export). For horizontal vibration motor, it can be adjusted according to the following steps when used:

  1. Loosen fastening screws of the protective cover, remove the shield at both two ends;
  2. The vibration motor whose excited vibration force is less than MV50-2, MV50-4, MV50-6, MV30-8 of (does not contain the four specifications), the outer eccentric block is adjustable, the surface is equipped with the rod which is indicated with maximum excitation force percentage, the inner eccentric block is fixed, they are all pressed on the motor shaft by the use of fastening bolts.

Two ends surface of the rotation axis are inscribed with datum line. Unscrew fastening bolts of of the eccentric block on both sides, the outer sides of the eccentric block rotating  in the same direction to make the shaft groove aim at the exciting fiorce gauge reticle on the outer eccentric block, adjust it to the required  excitation force, tighten fastening bolts of external eccentric block, and then mount the protective cover;

  1. The vibration motor whose excitation force is greater than or equal to MV50-2, MV50-4, MV50-6, MV30-8 of (including these four kinds of specifications), the outer eccentric block is fixed and fixed on the rotating shaft with the key, it can not rotate. The inner eccentric block can be adjusted, and the surface is provided with a ruler with the maximum excitation force which is pressed on the motor shaft by the use of fastening bolt. Unscrew fastening bolts of the eccentric block on both sides, the eccentric block on both sides rotate in the same direction, which make the exciting force ruler engraved lines on the inner eccentric block aligned the slotting of external eccentric block and adjust it to the required excitation force, tighten the fastening bolts of inner eccentric block and mount the protective cover;

Note: Except for special applications, the position of eccentric block on the two sides of the vibration motor shaft must be relatively, the percent set of eccentric block on both ends must be same, or vibration motor will produce a huge vibration force, which will damage the motor vibration machinery.
