表面振动压实仪工作原理：

振动夯板在试样表面做垂直振动压实被自上而下传播，颗粒菱角剪裁破碎后，颗粒位置重新排列，移动到相应于土工试验规格标准条件下的稳定位置，从而土体得到压实。

Working principle of surface vibration compactor:

The vibration tamping plate is propagated vertically from the top to bottom of the sample. After the particles are cut and broken, the position of the particles is rearranged and moved to a stable position corresponding to the standard conditions of the geotechnical test.

Instructions for use of surface vibration compactor:

★ Install a suitable test cylinder and compact the test cylinder to take an appropriate amount of soil sample. Use the specified tools to load the test sample and roughly scratch the surface of the sample.

★ Make sure that the power of the three-phase line is well connected, and the power indicator on the controller panel is on.

★ Press the up, stop and down buttons on the controller, the vibration motor and the weights move freely.

★ When pressing the ascending switch, the vibrator will fall down or pressing the down switch, the vibrator will rise instead, the power cord should be inverted. Otherwise, the upper and lower stroke switches will not work, and it is easy to damage the machine.

★ Press the down button once, the large sliding sleeve drives the vibration plate and tamping plate to drop. When the tamping plate contacts the loose soil sample, the large sliding sleeve will continue to fall, and it will drop to the lower end of the sliding sleeve, 15-25mm away from the vibration plate flange When you press the stop button once, the large slide sleeve stops descending.

★ Set the timer on the controller. The set time is 6 minutes. Press the vibration switch to start the vibration. The timer displays the vibration time. After 6 minutes, the moving plate will automatically stop.

★ Press the up button, the sleeve will drive the vibrating plate, the tamping plate will rise, and it will rise to 15-25mm below the top box of the stop block. Press the stop button once, and the big slide will stop rising.

★ Add a second soil sample in accordance with the test procedures, repeat the above operation steps twice, and one sample ** is calculated as the vibration compaction is completed.

★ Press the "Up", "Stop" and "Down" buttons on the controller, and the vibration motor and counterweight can move freely.

★ When pressing the ascending switch, the vibrator will fall down or pressing the down switch, the vibrator will rise instead, the power cord should be inverted. Otherwise, the upper and lower stroke switches will not work, and it is easy to damage the machine.

★ Press the "Down" button, the large sliding sleeve will drive the vibration plate and tamping plate to drop. When the tamping plate contacts the loose soil sample, the large sliding sleeve will continue to descend, descending to the lower end of the large sliding sleeve, away from the edge of the vibration plate At 15-25mm, press the "Stop" button once, and the large sliding sleeve will stop descending.

★ Set the timer on the controller. The set time is 6 minutes (that is, the black pull switch is in the middle position, and the dial number is 060).

★ Press the "Vibration" switch, the vibration starts to vibrate, the timer displays the vibration time, and the moving plate stops automatically after 6 minutes.

★ Press the "rise" button, the sleeve drives the vibration plate, the tamping plate rises, rises to 15-25mm below the top box of the stop block, presses the "stop" button, and the large slide stops rising.

★ Add a second soil sample in accordance with the test procedures, repeat the above operation steps twice, and one sample ** is calculated as the vibration compaction is completed.

★ Remove the test cylinder, use a straight steel ruler, place it in the diameter of the test cylinder, measure the data according to the regulations and then weigh it.

★ Data sorting calculation.

表面振动压实仪使用注意事项:

1、本机安装时,A好浇注混凝土基础上,以求机器工作稳定,在混凝土基位上 垫 8-10mm 橡胶板,以减轻振动。

2、在滑动部分及有黄油咀部位定加润滑油脂. 每次操作试验前应清除立柱外表面灰尘,应加注机械油20#。

Notes on the use of surface vibration compactor:

1. When the machine is installed, A should be poured on the concrete foundation to ensure the stable operation of the machine. Place 8-10mm rubber plate on the concrete base to reduce vibration.

2. Add lubricating grease to the sliding part and the part with a grease nipple. Before each operation test, the dust on the outer surface of the column should be removed, and mechanical oil 20 # should be filled.
