High Frequency 5～2,600Hz Vertical Electrodynamics Vibration Shaker Test Machine
Introduction:
Vibration Shaker Test Machine is also called vibration exciter or vibration generator.It is a device that USES electric, electro-hydraulic, piezoelectric or other principles to obtain mechanical vibration.The idea is to feed a excitation signal into a coil in a magnetic field to drive a table connected to the coil.The electrodynamic vibration table is mainly used for vibration measurement above 10Hz, with a maximum excitation pressure of 200N.In the frequency range below 20Hz, electro-hydraulic vibration table is often used. At this time, the nature of the vibration signal is controlled by the electric servo system.Hydraulic drive system can give greater displacement and impact.The vibration table can be used for accelerometer calibration, vibration performance measurement and vibration test of electroacoustic devices.For different test objects and technical indicators, attention should be paid to the selection of different structures and excitation range of the vibration table.

Characteristics:
Ultra mute work; The machine base uses the high quality material, installs conveniently, the operation is smooth, does not need to install the The, the control circuit digitization control and the display frequency, the PID adjusts the function, causes the equipment work to be more stable, reliable, sweeps the frequency and the fixed frequency operation way, adapts to the different profession test request To solve the interference of the strong electromagnetic field to the control circuit, and to increase the working time set, so that the test product reaches the accurate test time.
How to use:
1, the control manual to complete the procedure
2, such as Operation error so that can not work, you can use the recovery method of the steps of the input, and then set a single group or other running steps.
3, before use to press the external start switch, appears COO namely lets go, opens the key.
4, Taiwan Body:
1 The table body foot sleeve as far as possible fixed
2 power supply on/work in the output line can not be unplugged
3 Place the level as far as possible
4 components can be changed, the line should not be changed or from the connection.
5, the amplitude inside the code
1. Do not adjust too large before or after the boot
2) low-key amplitude of high amplitude modulation
3 Control Panel Amplitude Knob placed in the middle position test items: placed to focus on the main point, reduce the left flat right.
6, Inside Code:
1) reset when running or operating incorrectly
2) Control The Reset method step, each inside code only set one time to save can
7, Control Box:
1) The connecting line of the body must be locked tightly after hanging
2 the vibration direction switch and the output connection line are correspondence, can not connect the wrong
8, testing: Non-special test should use full wave test
9, the Taiwan body: can not produce the collision sound, the upper and lower center axis mutual touch will cause the spring steel piece rupture to be immediately shut down, amplitude modulation is adjusted small then turns on.
10, other unknown:
Do not arbitrarily change internal components and lines
11, the reason is bad:
1 The use of computer models can not be used for shaking table control
2 can not reload the driver
2, for the Ista-ia test, the operator to protect the sample, to prevent the test pieces slide out of the table;
3, gear gearbox replacement regularly;
