3、 Working principle

The instrument mainly consists of vibration components, frame components, and proximity switch programmable system, as shown in the figure2During operation, the synchronous motor drives the cam to rotate, causing the vibrating components to rise and fall to a fixed value, resulting in vibration that solidifies the cement mortar under the action of force. The instrument is controlled by a LCD touch screen,60 Automatically stop after next time.After the experiment is completed, the LCD screen displays that the set number of times has been reached and an alarm prompt begins. Press the confirm button to proceed.

4、 Installation

The correct installation of the vibration table is crucial for the production of specimens and test results. Please follow the following steps during installation.

1According to national standardsGB／T17671in4.2.5Requirement: The vibration table should be installed at a height of approximately400mmOn a concrete pedestal. The volume of concrete is approximately0.27㎡3Re appointment650kgWhen it is necessary to prevent external vibrations from affecting the compaction effect, a layer of about thickness can be placed under the entire concrete base5mmNatural rubber elastic pad. And pay attention to the good electrical safety grounding of the body.

2Fix the vibration table on the base with anchor screws, and install it in a horizontal state. Use a height ruler to correct the height difference of the four corners of the vibration table surface1mmWithin, the length direction is horizontal0.5mmLay a layer of fresh thick mortar between the instrument base and the pedestal to ensure their proper contact. This method can also be used to adjust the tabletop and arm to be horizontal.

3After the cement mortar sets and hardens, tighten the foot screws, paying attention to the consistent tightening force to prevent equipment deformation, and then proceed with the diagram2The middle table shown（7）Lift up, convex head（8）With positioning sleeve（10）There should be no jamming phenomenon. If jamming phenomenon is found, it is generally due to the lack of horizontal calibration, and the cause should be found before calibration.

4The position of the anchor screws is shown in the diagram:

Note:

1）When pouring the concrete base, the base should be kept at a distance of one person standing on the wall (approximately600Millimeters, convenient for installing and fixing screws.

2）Size（775＋120）x210The six of themM10Install the host frame with anchor bolts.

3）Size830x450The four of themM10Install the sound insulation cover with the anchor bolts, and refer to the external dimensions in Figure 1.

5、 Usage and maintenance

1Before operation, the positioning sleeve should be removed (see figure)2Check if all moving parts can move freely and if the electronic control part is normal. After adding lubricating oil, turn on the machine and run it idle. Only when everything is normal can it be used. The positioning sleeve must be removed before each use.

2Since this circuit does not use a power transformer, the circuit part is related to the power supply voltage, and the shell must ensure safe grounding (carefully check the power plug socket)PEIs the yellow green wire safely grounded instead of the power neutral wire.

3Add lubricating oil to areas with oil cups, and thin coat the cam surface with engine oil to reduce wear.

4After use, all kinds of debris on the instrument should be cleaned, kept clean, and the positioning sleeve should be placed in its original position to avoid the center position being affected by the force on the table.

5After a period of use, if the amplitude of the instrument increases beyond the tolerance, it can be adjusted with a randomly attached washer. The specific method is to loosen the fixing screw of the stopper, remove the stopper, place the washer underneath, and tighten the fixing screw again.

6Amplitude test:

aRandomly attach14.7mmPlace the inspection block in the diagram2Between the convex surface and the stopper, manually move the cam, which should be in contact with the bearing.

bUsing the same method15.3mmIf the inspection block is placed, the cam and bearing should not come into contact. If the above two conditions are met, the instrument amplitude is qualified. Only then can work be carried out.
