surface vibration compaction test instruments - BZYS-4212

BZYS-4212 type surface vibration compaction test instruments

This instrument is the surface vibration compaction method for cohesionless soil drainage grain and the freedom of soil (including of rockfill) maximum dry density of the test instruments

to EN12697-10, EN12697-31, ASTM D6925, SHRP M-002, AASHTO T312

Vibrating Compactor

The main technical parameters:

1, the power supply voltage: 380 V

2, consumed power: more than 1000 W

3, vibration frequency: 30-frequency 50 HZ

4, shock: 10-80 KN

5, ram plate role in sample surface static pressure: 18 KPa above

6, try tube specification: steel tube a large diameter 280 mm

7, steel small tube a 152 mm in diameter

A: the installation of the right to try pressure cylinder cylinder try apply adequate amount of soil sample, the provisions of the tool into try with body, scraping the roughly flat surface.

2: confirm three-phase line power connection is good, the controller panel on the power indicator was on.

3: press the controller rising, stop, down key, vibration motor and all the parts counterweight sports freely.

4: when you press the switch up, down or press vibrator instead decline switch, vibrators instead rise, shall fall the power cord. Otherwise up and down the switch is not effective, easy to damage the machine.

Five; Click the button down, sliding driven plate and vibration of ram plate dropped, when ram plate access to loose soil samples, sliding sets will continue to fall, down to the end of sliding, is apart from the vibration plate margins at 15 to 25 mm to press the stop button when, big slide set of stop falling.

6: set controller timer, set for 6 minutes, press the vibration switch, vibration began to vibration, the timer display vibration time, to six minutes after moving board to be automatic stop.

7: press the buttons up, set of driving vibration plate, ram plate rise and rise to the limit of end face and speed box below 15 to 25 mm, press the stop button, big stop the board to rise.

8: according to the test procedures and the second soil samples, repeat steps 2 times, a sample even if vibration compaction finished.

9: remove test tube, with a straight ruler, try tube diameter in position, according to the regulations measuring data weighing again.

10: data calculation. Surface vibration compaction instrument
