全自动一体沥青抽提仪操作规程:

★仪器的安装与连接

沥青含量快速抽提仪必需置于有顶面防护的房间或棚子中,距离墙面100cm。仪器底座放置好后,应该校正水平,然后才能放置蒸发冷凝箱,连接控制仪和冷却水管,在确认出380V及零线供电正常的情况下,黑色线为零线将仪器接通电源。

★使用前的检查

仪器在长途运输和长时间不用,再度使用前首先进行必要的检查和运转,确保安全A,以防发生意外。

⒈从溶剂孔注入三氯乙烯溶剂(约二十公斤)

⒉检查仪器工作是否正常:接通电源,启动工作开关,再按冲振及抽提键,使控制部分将进入工作状态。

⒊检查离心杯运转是否正常,按抽提键,此时离心机处于A级转速运转,观察其转向,正常状态下离心机按逆时针方向旋转〔与电机旋转方向(箭头方向)一致〕。

 

⒋检查喷淋盖内喷头是否堵塞。

★试验准备

⒈取下筛网,按孔径依次从小到大自下而上放好,将称量过的沥青混合料试样放入最上层的筛中。

⒉将整套筛网放在振动架的漏斗上,盖上喷淋盖,旋紧螺栓。

⒊将称量好的离心杯压入离心筒内,盖上离心盖,放正振动器支架,旋紧手柄,将导流管插入离心盖的中心孔内。

四油石比的计算

沥青混合料中矿料的总质量由两部分组成。

mα=m1+m2

式中:mα-沥青混合料中矿料的总质量(g)

m1-筛网中倒出的集料烘干后的质量(g)

m2-离心杯滤纸试验前后的增量(g)

沥青混合料中沥青质量为沥青混合料总质量与矿料总质量之差。

mb=m-mα

式中:mb-沥青混合料中沥青质量(g)

m-沥青混料总质量(g)

mα-沥青混合料中矿料总质量(g)

沥青混合料的油石比,可由下式求得:

pα=m-mα/mα×100%

式中: pα-沥青混合料的石油比(%)

Automatic asphalt extraction instrument operating procedures:
★ Instrument installation and connection
The asphalt content rapid extractor must be placed in a room or shed with a top protection, 100 cm from the wall. After the instrument base is placed, the level should be corrected before the evaporative condensation chamber can be placed, and the controller and cooling water pipe can be connected. When the 380V and neutral power supply are confirmed to be normal, the black line is turned off and the instrument is powered on.
★Check before use
The instrument is transported over long distances and unused for a long time. Before re-use, first carry out the necessary inspection and operation to ensure safety A to prevent accidents.
1. Inject trichloroethylene solvent (about 20 kg) from the solvent hole.
2. Check whether the instrument works normally: turn on the power, start the work switch, and then press the shock and extraction keys to make the control part enter the working state.
3. Check if the operation of the centrifuge cup is normal. Press the extraction button. At this time, the centrifuge is running at the A-speed. Observe the steering. In the normal state, the centrifuge rotates counterclockwise [consistent with the motor rotation direction (arrow direction)].

4. Check if the nozzle inside the spray cover is clogged.
★Test preparation
1. Remove the screen, place it from bottom to top according to the pore size, and place the weighed asphalt mixture sample into the topmost sieve.
2. Place the entire screen on the funnel of the vibrating frame, cover the spray cover, and tighten the bolts.
3. Press the weighed centrifuge cup into the centrifuge tube, cover the centrifuge cover, place the vibrator bracket, tighten the handle, and insert the guide tube into the center hole of the centrifuge cover.
Calculation of four oil-stone ratio
The total mass of the mineral in the asphalt mixture consists of two parts.
Mα=m1+m2
Where: the total mass of the mineral in the mα-asphalt mixture (g)
The mass of the aggregate after pouring out in the m1-screen (g)
M2-centre cup filter paper before and after the test (g)
The asphalt quality in the asphalt mixture is the difference between the total mass of the asphalt mixture and the total mass of the mineral material.
Mb=m-mα
Where: asphalt quality in mb-asphalt mixture (g)
M-asphalt compound total mass (g)
Total mass of mineral material in mα-asphalt mixture (g)
The oil-stone ratio of the asphalt mixture can be obtained by the following formula:
Pα=m-mα/mα×100%
Where: oil ratio of pα-asphalt mixture (%)

 

全自动一体沥青抽提仪使用注意事项

★当全自动沥青含量快速抽提仪在抽提的过程中,因停电而中断抽提时,不能带载2次启动,否则会因离心杯中的矿粉,沥青和三氯乙烯混合液引起重心偏移,损坏离心筒,因此抽提停电,必需清理试样及离心杯,按新的试验重新开始。

★长途运输时,要特别注意防震,仪器设备要分别装入专用包装箱,箱内垫以塑料泡沫或软纸,四周填充密实,勿使之松动摇晃,装卸车时小心轻放,不能碰撞,以确保仪器外表美观,功能完好。

★仪器两天以上不使用,要将蒸发箱的沥青,三氯乙烯混合液和溶剂箱的三氯乙烯放出,分别存放在专用密封塑料筒内,以防对仪器腐蚀。

★离心筒,离心机顶盖两个部位的密封圈,每使用一次涂一次凡士林油。

★由于安装使用不当,或仪器设备发生故障,会使试验无法正常进行。如果仪器严重损坏必须交有关人员检修。

Automatic asphalt extractor use precautions
★When the automatic asphalt content rapid extraction instrument is interrupted during the extraction process due to power failure, it cannot be loaded twice, otherwise it will be caused by the mineral powder, asphalt and trichloroethylene mixture in the centrifuge cup. The center of gravity is offset and the centrifuge tube is damaged. Therefore, the power is removed and the sample and the centrifuge cup must be cleaned and restarted according to the new test.
★When transporting long-distance, pay special attention to shockproof. The equipment should be packed into special packing box. The inner cushion of the box should be filled with plastic foam or soft paper. The surrounding area should be densely packed. Do not make it loose and shake. When loading and unloading the truck, be careful and handle it. To ensure that the appearance of the instrument is beautiful and functional.
★ If the instrument is not used for more than two days, the asphalt of the evaporation box, the trichloroethylene mixture and the solvent box of trichloroethylene should be released and stored in a special sealed plastic cylinder to prevent corrosion of the instrument.
★ Centrifuge tube, seal ring on the top of the centrifuge top cover, apply Vaseline oil once every time.
★Because of improper installation or equipment failure, the test will not work properly. If the instrument is seriously damaged, it must be handed over to the person concerned for inspection.
