TSX over the years has been committed to the manufacture and research of vibrating screen industry, recently there are often customers call to inquire about the running speed of vibrating screen, and material.
The problem of the maximum processing capacity of materials, today to analyze – under this aspect of the problem.
- 1. The calculation method of linear vibration material running speed is as follows:
v=kv*λ*ω*cos(δ) *https://www.xxhongda.net/ vibration motor
https://www.cbzdq.com/ Bin wall vibrator [1+tg(6)*tg(x)]
v=kv*\*ω2* ( 1+ ) *a
Where kv: comprehensive empirical coefficient, generally 0.75 ~0.95
λ: single amplitude in mm
ω: vibration frequency, expressed in rad/s
The main parameters of the vibration motor are vibration force, vibration frequency, amplitude, power and motor series. The vibration pattern produces by a single vibration motor mounted on the equipment is usually circular vibration without direcTIONality, and the combination of more than two vibration motors use a variety of vibration patterns that can be generated.
Two, as the most basic elements of vibration are vibration frequency and amplitude, from which the velocity (vibration frequency x amplitude), and acceleration (frequency of Square x amplitude)
Three, vibration frequency
Frequency is measured in times per second, also known as Hertz. In the vibration motor is by its pole number and the number of cycles the calculation.
Four, amplitude and acceleration:
In the vibration with the center of mass, the distance Ym from the center of mass to the maximum displacement is called the amplitude. In the vibration application, the distance between the maximum displacements S (double vibration).In the vibration system using vibration motor, the determination of amplitude is very important.
When the motor is energized and rotated, the exciting block generates the exciting force, which is transmitted through the bottom Angle or flange of the motor
Vertical and horizontal vibration machinery. The vibration motor is composed of special stator line package and rotor shaft, which can withstand high frequency vibration. The horizontal vibration motor adopts four fan eccentric blocks
As an exciting block, the Angle between two eccentric blocks at the coaxial end can be adjusted from zero to the maximum vibration force of the vibration motor.
The vibration motor is energized and rotates, drives the eccentric block at both ends of the motor shaft, and generates the inertial excitation force, which is the spatial rotation force, and its amplitude is Fm,
Fm=mrω2.
m —a eccentric block mass
r-—The distance of the center of mass rotation axis of the eccentric block, that is, the eccentricity
ω— a motor rotation Angle frequency
P—I n / 60 ω = 2
n —Vibration times of the vibration motor
From this formula, the amplitude (amplitude) of the 2, 4 and 6 level vibration motor can be obtained.
