How to choose the vibration motor correctly
How to choose a suitable vibration motor, the main reference to the following two aspects:1, according to the production requirements and vibration sieve categories, first determine the required motor vibration times n (r/min) and double amplitude S (mm).1) six stage vibrating motor (n=980r/min), (S=8-12mm) suitable for multilayer vibrating screen, circular vibrating screen, long distance conveyor.2) four stage vibrating motor (n=1460r/min), (S=4-8mm) suitable for light linear screening machine, rotary vibrating screen, feeder.3) two stage vibrating motor (n=2870r/min), (S=2-4mm) suitable for high frequency vibrating screen, vibrating table and silo block.
The characteristics of the vibration motor is the lower the speed, the amplitude of the higher vibration motor each turn, the material in the sieve surface was thrown up once, along the parabolic fixed path forward or jump up and down, so that the materials are screening or tap processing.
Secondly, the required exciting force is determined.Type designation of vibration motor, such as: XV 20-6The XV model (model, motor mounting center hole distance is not the same), 20 said the exciting force of 20 kn, the equivalent of 1 KN 100 KG 6, said six step motor, the speed of 980R/min. Calculate the weight of the vibrating part above the spring of the vibrating equipment and the total weight (including the weight of the vibrating motor) after carrying the material. For example: the total weight of the equipment is 1000KG, the use of a vibration motor to do the excitation source, it is necessary to select 16 KN or 20 KN, using two vibration motors as excitation source, it is necessary to choose 8 KN or 10KN, this is because the choice of vibration motor vibration force must be higher than 30% of the total weight of the equipment, and can not be equal to the two, otherwise it will form a small horse cart phenomenon, easy to cause vibration, motor overload damage.
