First, this machine is suitable for the determination of asphalt content of asphalt mixing in viscous oil (or aggregate ratio) of asphalt and asphalt dosage.

Two, DLC-5 computer asphalt rapid extraction instrument structure

The instrument adopts the automatic balance device, and automatic control technology and automatic digital control circuit, compact structure, stable operation, automatic timing, automatic shutdown, laboratory instrument is advanced.

Three, technical parameters

1, speed: 0~3000r/min

2, time: 0~999s arbitrary settings

3, the power supply voltage: 50HZ AC220V

4, centrifugal cup capacity: 1500g 3000g

Four, the use of methods

1, time adjustment: according to the power supply, the time control window shows the number of the current digital dial, the unit is seconds. According to the ministerial standards, the test time is no longer out of the liquid outlet centrifuge solution after downtime, this time is generally between 90~180 seconds, so the centrifugal time according to the first test time to adjust. The digital dial can adjust time.

2, according to the test procedures for the preparation of asphalt mixture sample.

3, the mixture and solvent all into the centrifugal cup.

4, said to take clean ring filter, accurate to 0.01g (Note: filter paper can not be repeated use, there is no damage to the use of). General filter paper should be put two.

5, the filter paper pad on the edge of the centrifugal cup, the seal is fixed tightly, the collector cover is tightly fastened, and the collecting bottle is placed at the outlet of the collector.

6, open the machine after the power switch on the panel, adjust the time control circuit (the digital dial), open the switch, the centrifugal cup begins to rotate, to reach the setting time, the instrument automatically shut down.

7, from the new solvent, cover the hole number before, pause 3~5 minutes after the restart, so test, test times, until out of the solution with the injected solvent cleaning test the same color so far.

Five, DLC-5 computer asphalt rapid extraction equipment notes

1, the instrument is equipped with filter paper as a special oil filter filter, if the use of mineral loss too much, users should consider the number increases each time using filter paper (such as three), to meet the requirements of ore loss.

2, the extent of loss of powder and centrifugal cup cover pressing degree, does not affect the rotation of the case, the nut should be tightened.

3, solvent injection centrifugal cup should prevent spills machine in vitro, if there is a spill should immediately clean, prevent accidents.

Six, maintenance

1, after each use should immediately clean the inside and outside parts of the instrument, especially the spindle and the centrifugal cup, the upper cover and the lower base of the cooperation.

2, on top of the bearing cover should often add a little oil to lubricate.

Seven, can be used for supporting equipment

1, asphalt mixture automatic mixing machine

2, digital display Marshall automatic compaction instrument

3, computer Marshall stability tester

4, automatic digital penetration instrument

5, automatic digital display asphalt extension

Eight, packing list

1, host: 1

2, ring filter paper: 10

3, qualified certificate: 1 copies

4, manual: 1 copies
