How to select the Marshall electric compactor operating procedures First, first connect the three plugs behind the cabinet. "Motor" to be connected to the cabinet motor input, "non-contact proximity switch" received count socket. The “power supply†is connected to the power outlet, and the zero line must be connected.
2. After the above work is done, pull the “preset†dial and set the number of shots from 1 to 99 as required. Turn on the power switch panel and the digital display shows "00" power indicator light.
Third, press the start button controller to start work, the status light is on, the digital light shows "00" motor rotation, lift hammer hit real, each time a digital tube plus a number, to achieve the setting after hitting the motor stopped, the light off.
4. Press the Pause button to stop the work and the status indicator is off. Press the Start button again. The work returns to normal. If there is an abnormal situation during work, press the Pause button. At this time, the digital tube displays the number of hits. After an experiment, press the clear key first, then press the start key
How to select the main technical indicators of Marshall Electric Compactor Drop hammer: (475±1.5)mm
Hammer number: 60±5 times/minute Compact number of presets: 0-99 Hammer weight: 4536±5g
Test tube diameter: 101.6mm
Common fault detection
How to Choose Common Faults and Elimination of Marshall Electric Compactor
1 Do not lift the hammer during work or pull off the hammer during lifting. Check whether the drive chain is loose, such as adjusting the loose bolt after loosening. Whether the shrapnel on the hammer is damaged or not and need to be replaced. The pick hammer block and the hammer hammer key are worn too much.
2 The display shows an abnormal number or does not count. Check the proximity switch at the upper drive wheel for loose or near distance.
3 The entire display does not appear when the power switch is turned on. Check if the power supply is normal or if the rear fuse of the distribution box is blown.
4 Lift off the hammer together with the guide bar. Is the chain too loose, lack of grease or dirt on the guide rod?
main feature:
1, can achieve automatic counting, automatic compaction, automatic shutdown.
2, with a hammer holder, and manual handle, you can easily lift the hammer.
3, semi-automatic die device, take the mold more convenient.
4, integrated hammer, will not fall off, will not break off, cracking
How to select Marshall Electric Compactor Applicable scope:
Suitable for standard compaction method to make asphalt mixture test specimens for laboratory use to test the physical and mechanical properties of asphalt mixture, also applicable to Marshall test, indirect tensile test used Φ152mm ± 0.2mm × 115mm/Φ101. Molding of 6mm ± 0.2mm × 63.5mm cylindrical specimens.
Operation method
a. Each time before compaction, the compacting head, the inner wall of the trial mold and the base of the trial mold should be brushed with engine oil.
b. Open the safety door, lift the slide rails and weights, and use the safety lever to lock the impact head.
c. According to the specification, mix the well-mixed asphalt mixture into the test mold, push the test mold into the trial mold positioning pin of the steel plate platform, and lock the test mold.
d. Raise the guide rod and weight, open the safety lever, put down the compaction head, close the safety door, and press the start button to start pressing the start button and automatically shut down when the set number of times is reached.
How to select the use of Marshall electric compactor precautions
1. The counter counts in positive count.
2. The next time you hit the realm, press the reset button and press the start button.
3. Press the stop button to stop the compactor when the compaction needs to be stopped or the machine is faulty.
4. The tension of the chain should be checked regularly and adjustments should be made if the deflection is greater than 10mm.
5. Do not start the compactor when it is not loaded. When not in use, place a cotton yarn or scraps of paper in the trial mold.
6. Regularly lubricate the sliding parts of the chain and weight.
7. After each compaction is completed, the trial mold, compacting head, and steel plate platform should be cleaned.
8. The tension of the steel plate platform and the concrete base should always be checked.
