Product description
Exciter (vibration) is a device which is used to generate the excitation force on some machines and equipment. The exciter can obtain the vibration quantity and the intensity of the object to obtain the certain form and the size, thus carries on the vibration and the strength test to the object, or carries on the calibration to the vibration test instrument and the sensor. The exciter excitation can be used as components of mechanical vibration, work for the realization of the object or material conveying, screening, compacting and molding sand and soil tamping etc..
Matching mode
Exciter of various types have different mechanical effects - whether eccentric shaft or eccentric block through a combination of different models, all single shaft vibration exciter to drive the corresponding equipment to do circular motion, single shaft vibration exciter all dual shaft vibration exciter or two sets of the same type and specification and column pile distribution, and running the opposite direction, the corresponding driving equipment approximately linear vibration; so as to meet the actual demand, here are typical common mode in practical engineering"
A, single arrangement of single axis exciter
This model makes the device body to do approximate circular motion, such as a variety of circular vibrating screen which is widely used in practical engineering;
B, a single arrangement of the two axis exciter
This model uses the device body to do approximate linear motion, such as the actual engineering widely used linear vibrating screen, vibration feeding or conveyor is such a model;
Series arrangement of C. biaxial vibration exciter
This model is exactly the same as the mechanical effect of the single arrangement, which is equivalent to extending the power range of the previous mode;
D. single axis vibration exciter two or three sets, the same direction but different rotation speed.
This model forms the device body to do nonlinear motion. Such as the BPS type frequency screening sieve which belongs to this model; and other inertial vibrating screen is different, this pattern from the feed end to the discharge end, the vibration frequency of the sieve box body sieve and track material is nonlinear; i.e. all amplitude and frequency of vibration according to certain rules changed. Fully meet the screening operation in large amplitude discharge end, low frequency and high frequency discharge, small amplitude, and under the same conditions, have higher screening efficiency and large processing capacity.
E. single axis vibration exciter (usually three) arranged in different directions
The arrangement of this type of exciter is usually the same as "two" (Group) synchronization, the same direction, and the other (Group) with the synchronization, the opposite direction of rotation. In this mode, the vibration of the device can be used to form the motion of the vibrating body, such as the large conical vibrating screen which is widely used in engineering.
F. single axis vibration exciter arrangement in the same direction
This mode of the exciter arrangement is usually single shaft vibration exciter parallel three or more than three of the same model and specifications, the mechanical effect is the formation of Dazhui Park Movement screening operation, such as the so-called "strong screen" is the mode of application;
G. vertical vibration motor or exciter is designed for rotary screen vibration source design, due to the special structure, the vibration source in different conditions (i.e. vibration motor or vibration exciter under eccentric relative phase) have different mechanical effects, and to a different screen effect;
H. 3D vibration exciter as mentioned before, the three-dimensional vibration exciter is a kind of special, specifically for the adaptation of power device of swinging screen design, selection of such exciter is the technical work is very complex, how should choose from the specialized technical personnel according to the equipment operating environment and the industrial circumstances;
Adjustment of exciting force of I. exciter
All kinds of vibration exciter used in engineering, the size of the exciting force can be adjusted in a certain range. From the working principle of vibrator in general and special nature of the exciting force from the vibration source can be considered to be inherent in the eccentric mass around a fixed axis rotation direction of a centrifugal force periodically varying, the size and quality of the eccentric block m, eccentricity R and exciter is the working speed of rotation angle the relationship between velocity:
Fe=mere Omega 2
In the formula, =2 N/60 N for the Omega Omega motor speed (PRM), we can according to the specific circumstances through the eccentric mass me, eccentric adjusting working speed and distance of re exciter is the rotation angular velocity, has to adjust the exciter force to
