Installation method of cement mortar vibrating table
The correct installation of cement mortar vibrating table is crucial to the production of specimens and test results. Important, please follow the steps below when installing.
According to the requirements in national standard B, the vibrating table is installed on a concrete base with a height of approximately. The volume of concrete is approx., and the weight is approx. When it is necessary to prevent external vibration from affecting the vibration effect, a layer of natural rubber elastic liner about the thickness of the entire concrete base can be placed. And pay attention to the fact that the machine body should have good electrical safety grounding.
. Fix the vibrating table to the base with anchor screws. After installation, it will be in a horizontal state. You can use a height ruler to correct the height of the four corners of the vibrating table and the horizontal direction of the length within. The base of the instrument and the base Place a fresh layer of thick mortar between them to ensure they are in complete contact. At the same time, this method can also be used to adjust the table and arm to be level.
After the cement mortar has solidified and hardened, tighten the anchor screws. Note that the tightening force should be basically the same to prevent the equipment from deforming. Then lift the table as shown in the picture. There should be no obstruction between the protruding head and the positioning sleeve. If any jamming is found, the level is generally not calibrated, and the cause should be found before calibration.
. The location of the anchor screws is as shown in the diagram:
Use and maintenance of cement mortar vibrating table
. Before operation, the positioning sleeve should be removed and check whether the moving parts can move freely. The electronic control part If it is normal, add lubricating oil, start the machine and run it idling, and check that everything is normal before use. The positioning sleeve must be removed before each use.
Please see the attached figure for the electrical principle. Before the power is turned on, the lock switch is in the closed state (that is, the button pops up position). Press the switch and lock it, the motor runs, the electronic counter counts from zero, and stops when it reaches the time limit. To operate again, you can press and release twice to repeat the operation.
Since this circuit does not use a power transformer, the circuit part is related to the power supply voltage, and the outer casing must be safely grounded (carefully check whether the yellow and green wires of the power plug socket are safely grounded, not the neutral wire of the power supply.
. Add lubricating oil where there is an oil cup, and apply a thin layer of engine oil on the surface of the cam to reduce wear.
. After use, clean all kinds of debris on the instrument, keep it clean, and put the positioning sleeve in its original position to avoid The force on the table affects the center position.
After the instrument has been used for a period of time, if the amplitude becomes large and out of tolerance, it can be adjusted with the attached washer. The specific method is to loosen the stopper fixing screw and take out the stopper. , put the washer underneath and re-tighten the fixing screw.
, Amplitude test:
, Put the test block attached with the machine between the convex surface and the stopper as shown in the figure, and pull it by hand When moving the cam, the cam should be in contact with the bearing.
b. Use the same method to put in the inspection block, then the cam and the bearing should not be in contact. If the above two conditions are met, the instrument amplitude is qualified. Only then can the work be carried out.< br/> Overview of the cement mortar vibrating table
The cement mortar vibrating table is designed for my country's cement mortar strength testing method to adopt: () international standard. This instrument is equivalent to: () standard, It is suitable for the preparation of patterns used for cement strength testing.
Working principle
During operation, the synchronous engine drives the cam to rotate, causing the vibrating part to rise and move. After rising to a set value, it falls freely, and produces a frequency of The vibration causes the cement mortar type sample to be vibrated under the action of gravity.
Operating procedures for cement mortar vibrating table
. Remove the mold cover and fix the empty test mold and mold cover on the vibrating table. Use a suitable spoon to directly put the glue sand into the test mold in two layers from the mixing pot. When loading the first layer, put about 10% of the glue sand into each slot, use a large spreader, and place it vertically on the top of the mold sleeve. Spread the material layer back and forth along each mold slot once, and then tap it again. Then add the second layer of mortar, spread it flat with a small spreader, and tap it again.
.Note: Before connecting to the power supply The lock switch is in a closed state (i.e., the button pops up). Press the switch and lock it, the motor will run, and the electronic counter will count from zero and stop when it reaches the time limit. To operate again, you can press and release twice to repeat the operation.
.Remove the mold sleeve, take out the test mold from the vibration table, use a metal ruler to place it on one end of the top of the test mold at an approximate angle, and then slowly cut transversely along the length of the test mold. Slowly move to the other end, scrape off the glue that exceeds the test mold at a time, and use the same ruler to smooth the surface of the test object almost horizontally.
. Mark the test mold when it is close to final setting. Or add a note to indicate the specimen number and the position of the specimen relative to the vibrating table.
After use, cut off the power, wipe the vibrating table clean, keep the appearance clean and dust-free, and place the positioning sleeve in its original place. position to prevent the table from being affected by force and affecting the center position.
Precautions
. The distance between the proximity switch for counting and the cam should be maintained. During long-term use, care should be taken to prevent looseness to avoid malfunction.
. When working, the clamps should be locked tightly to avoid accidents.
. Pay attention to keeping the equipment clean and tidy. Clean the cement mortar in time and wipe it clean after each use.
. The controller should be protected from dust and moisture.

Working principle of cement mortar vibrating table
The instrument is mainly programmed by vibration components, frame components and proximity switches The system composition is shown in the figure. When working, the synchronous motor drives the cam to rotate, causing the vibrating component to rise and move. After rising to a fixed value, it falls, and the vibration is generated to vibrate the cement mortar under the action of force. The instrument uses proximity switch counting for automatic control. , automatically stops after the number of times, easy to use and accurate counting.
