Operation foundation of linear vibrating screen

ZKX type Linear vibrating screen It is suitable for wet separation, dewatering, desliming and degumming of ZKX fine materials, and suitable for screening of large, medium and fine particles. It is widely used in metallurgical mines, coal preparation plants, building materials and chemical industries.
 
Linear vibrating screen, also known as double axis inertial vibrating screen, is one of inertial vibrating screens. It has high productivity and screening efficiency.
 
The working principle of suspended linear vibrating screen is mainly composed of screen box, box vibrator, suspension damping device and driving device. The vibrator has two main shafts, and the magnetic powder clutch has the same eccentric weight with the same eccentricity on both shafts.
 
The component forces in the vertical X direction are superimposed on each other. As a result, the reciprocating exciting force is generated in the X direction, and the reciprocating linear track vibration of the screen box is generated in the X direction. The direction of excitation is 450 degrees. The movement of materials on the screen surface does not depend on the tilt of the screen surface, but on the direction and angle of vibration. Therefore, the screen surface of linear vibrating screen is small and flat.
 
A pair of gears with a speed ratio of 1 are connected between the two shafts. When the Han motor drives the spindle to rotate through the V-belt, the driven shaft rotates through the gear, and the rotation of the two shafts is the same and the direction is opposite. Therefore, the centrifugal inertial force generated by the eccentricity of the same weight on both axes is in the y-axis direction. Force components with opposite directions and equal dimensions cancel each other;
 
Preparation work before installation of linear vibrating screen
 
1. Check whether the motor label meets the requirements.
 
2. Measure insulation resistance with 500 V megohmmeter. The value should be dry and the stator winding should be dry. The drying temperature should not be higher than 120 ° C.
3. Check the motor fasteners and pay attention to looseness.
 
Check whether the motor is damaged or not.
 
5. Check whether the maneuver rotates. If there are, they should be removed.
 
6. Check the power supply for lack of phase, and run for 5 minutes without load.
 
Placement and adjustment of linear vibrating screen
 
1. The motor should be fixed on the installation surface, the placement surface must be smooth, and the screw conveyor should be flat.
 
2. The motor can be installed in quiet water.
 
3. Motor leads receive four core rubber cable yz-500v. When connecting the power supply, the lead cable is not allowed to be in emergency, and the vibration body is reliable and firm.
 
4. The motor shall be reliably grounded. There is a grounding device in the motor. There is a marker on the front. It can also be grounded with a strong bolt.
 
5. Mediation of exciting power.
