Electromagnetic vibration test bench is a non-standard product that exists in mechanical shaking table, hydraulic shaking table and electric shaking table.
It is a precision vibration equipment designed in China according to production needs
.
Widely used in national defense, aviation, aerospace, communications, electronics, automobiles, home appliances, and other industries, the working principle of electromagnetic vibration tables is similar to that of speakers
.
That is, the current-carrying conductor moves under the action of electromagnetic force in the magnetic field
.
When the moving coil in the magnetic circuit of the vibrating table passes the alternating current signal, the exciting force is generated in the magnetic circuit, and the vibration motion is generated
.
Features of electromagnetic vibration test bench: 1.
Using programmable technology, programs can be set, and multiple frequency sweeps can work at the same time; Digital control and display frequency, PID adjustment function, make the equipment work more stable and reliable; 4.
The control parameters are displayed synchronously in real time, and can be switched at any time without manual intervention; 5.
The control effect can be achieved, and the control curve can be predicted; 6 , Precise design and manufacture, split vertical and horizontal table body, beautiful appearance, work; 7.
The base adopts anti-vibration device, which is easy to install, runs smoothly, and does not need to be fixed; 8.
Embedded amplitude prediction program and easy amplitude modulation; 9 .
Nine-point synchronous excitation, the table vibrates evenly; 10.
Stepless amplitude adjustment, fixed frequency and frequency sweep operation functions to meet various test requirements in different industries; 11.
Add anti-interference filters to solve the interference of strong electromagnetic fields on the control circuit; 12.
Increase the working time setter to make the test product meet the better test requirements
.
The common faults of the equipment are sorted out and analyzed: Fault 1: The power switch light does not light up 1.
Check whether the external incoming power supply voltage is output and input to the power socket, and use a multimeter to measure whether the voltage is normal
.
2.
Check whether the fuse of the power socket of the control box is burnt and the switch is broken, and replace the fuse or switch
.
Fault 2: There is no display on the control panel when starting up.
1.
Check whether the switch on the control panel is damaged and whether there is a power supply.
Check whether the power supply voltage is 220V input and the wiring is connected.
There is no display
.
2.
Whether the communication signal line connecting the controller and the panel is in poor contact or falling off, just press or connect it again
.
Fault 3: The run light is on without vibration 1.
Check whether the function switch is pressed to ON, if not, please press it to ON or the vibration is small
.
2.
Check whether the vertical/horizontal direction of the three-axis switch is correct, and press to switch to vertical/horizontal
.
3.
Is the adjustment of CD003 and CD005 correct or too small? Reset CD003 and CD005
.
Fault 4: Frequent fuse burning 1.
The power supply voltage of the XYZ high-frequency vibration test bench is abnormal, check whether the external incoming line voltage is short-circuited, and re-process the fuse that burns when it is turned
on.
2.
Whether the fine-tuning amplitude modulation function is adjusted to a large value before starting the machine, it should be adjusted to 0 and then gradually increased
.
3.
Whether the machine works for a long time without load, resulting in overcurrent and short circuit protection of the machine
.
4.
Use the multimeter to measure the vertical feet 1 and 2 or the horizontal feet 3 and 4.
The two-point resistance values are normal within 1-200 ohms.
If the abnormality is not normal, the central axis is not good.
First judge whether the line connecting the central axis is short-circuited.
.
5.
The power supply of the control box is short-circuited, check whether the wire is off or burned out
