It should be noted that for controlling the control circuit of the intermittent rotation of motor 21, what the control circuit was selected is
The circuit that can realize the 21 intermittent rotation of control motor of the prior art, such as control circuit shown in fig. 6.
Control circuit connecting components according to figure 6 during experiment, are first closed power switch Q, and frequency converter is (existing at this time
There are the frequency converter of technology, such as the frequency converter of upper seamount space SY8000 series, SY8000-0R7G-2, SY8000-1R5G-
2) it is powered, adjusted frequency values is manually entered by the control panel of frequency converter, press operation button.Control circuit is set to position
In in switch board, pressing the start button SB on switch board1, at this point, relay K1Coil obtain electric, normally opened contact K10It closes
It closes, A.C. contactor KM coils obtain electric, main contacts closure, and main circuit is connected at this time, the frequency modulation electricity that motor 21 is exported in frequency converter
Pressure is started to work, and L-shaped is driven to lift platform shake table and starts to vibrate.Time relay KT1Coil be also powered, and start to count
When, while relay K2Coil obtain electric, normally-closed contact K21It disconnects.Elapsed time t1Afterwards, time relay KT1Normally opened prolong
When contact KT10It is closed, normally closed delayed contact KT11It disconnects, relay K2Coil blackout, normally-closed contact K21It is closed, therefore after
Electric appliance K3Coil be powered, normally-closed contact K31It disconnects, normally opened contact K30It is closed, at this time A.C. contactor KM coil blackouts, it is main
Contact disconnects, and main circuit disconnects, and motor 21 stops, and L-shaped lifts platform shake table and also stops vibrating.Time relay KT2Coil
It is powered, and starts timing, while relay K4Coil obtain electric, normally-closed contact K41It disconnects.Elapsed time t2Afterwards, time relay
Device KT2Normally opened delayed contact KT20It is closed, normally closed delayed contact KT21It is closed, relay K4Coil blackout, normally-closed contact
K41It is closed, therefore relay K1Coil be powered, normally opened contact K10It being closed, A.C. contactor KM coils are once again powered up at this time,
So that main circuit is again switched on, start working cycles next time.When by lower button SB0, control circuit power-off, disconnection is electric at this time
Source switch Q, L-shaped lifts platform, and also vibration mechine is stopped.
L-shaped lifts the vibration time t of platform1With intermittent time t2By two time relay KT in control circuit1And KT2
It is adjusted respectively, selects DH48S-S digital display time relays, delay time can be adjusted between 0.1s to 99h, can
Fully meet the requirement of vibration test.
Relay K1、K2、K3、K4Using the relay of the prior art, such as JT4 series alternating current electromagnetic relays.
Pass through fuse FU between power switch Q and frequency converter1Connection, while lead between A.C. contactor KM and ground wire
Cross fuse FU2Connection.
