The advantages of high frequency vibrator vibrating screen compared to ordinary vibrator

A low-power electric vibration exciter is used to drive the hydraulic servo valve to control the hydraulic pressure medium in the pipeline, and a large excitation force is generated on the piston in the hydraulic cylinder, so that the excited part is vibrated. Electricity flows into the moving coil, and the moving coil is driven by the periodically changing electromagnetic excitation force to drive the ejector rod to reciprocate. Contact the ejector pin with the excited part to obtain the expected vibration. Use the eccentric mass to rotate to generate the required excitation force. The unidirectional excitation force inertial vibration exciter is generally composed of two rotating shafts and a pair of gears with a speed ratio of 1. The two rotating shafts rotate in opposite directions at equal speed.

The two eccentric blocks on the shaft produce the resultant force of inertia in the Y direction. When working, fix the exciter on the excited part, and the excited part will obtain the required vibration. A self-synchronizing inertial vibration exciter is also widely used in vibration machinery. The two rotating shafts of this kind of vibration exciter are driven by two induction motors with similar characteristics, and do not use gears. The two rotating shafts with eccentric masses can realize constant speed and reverse rotation based on the principle of vibration synchronization, so as to obtain unidirectional excitation force.
The high-frequency vibrating screen exciter is a device attached to some machinery and equipment to generate excitation force, and is an important part of using mechanical vibration. The vibrating screen exciter can make the excited object obtain a certain form and magnitude of vibration, so as to perform vibration and strength test on the object, or to calibrate the vibration test instrument and sensor. The high-frequency vibration exciter can also be used as an excitation component to form a vibrating machine to realize the conveying, screening, compacting, shaping, and tamping of soil and gravel of materials or objects. According to the different excitation types, vibration exciters are divided into inertial electric, electromagnetic, electro-hydraulic, pneumatic and hydraulic types. The exciter can produce unidirectional or multidirectional, harmonic or non-harmonic exciting force.

The cyclically varying current is input to the electromagnet coil, and a cyclically varying excitation force is generated between the excited part and the electromagnet. The electromagnetic exciter used in vibration machinery is usually composed of an electromagnet core with a coil and an armature, and a spring is installed between the core and the armature. When AC power is input to the coil, or AC power plus DC power, or pulsating current after half-wave rectification, a cyclically varying excitation force can be generated. This kind of vibration exciter usually directly fixes the armature to the working part that needs to be vibrated.
