　　★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×**

　　式中：pα－沥青混合料的石油比（%）

　　Full-automatic asphalt extraction instrument operating procedures:

　　★Installation and connection of the instrument

　　The asphalt content rapid extraction instrument must be placed in a room or shed with a top surface protection,100 cm from the wall surface.After the base of the instrument is placed,the level should be corrected,and then the evaporative condensation box can be placed.Connect the controller and the cooling water pipe.After confirming that 380V and the neutral line power supply are normal,the black line is the neutral line to connect the instrument to the power supply.

　　★Check before use

　　The instrument is transported for long distances and is not used for a long time.Before it is used again,the necessary inspection and operation are performed to ensure safety A to prevent accidents.

　　注入Inject trichloroethylene solvent(about 20 kg)from the solvent hole

　　⒉Check whether the instrument works normally:Connect the power supply,start the work switch,and then press the shock and extraction keys,so that the control part will enter the working state.

　　⒊Check whether the centrifugal cup is operating normally,press the extraction button,the centrifuge is running at A speed,and observe its rotation.Under normal conditions,the centrifuge rotates counterclockwise[in line with the direction of rotation of the motor(arrow direction)].

　　Zh

　　⒋Check whether the spray head inside the spray cover is blocked.

　　★Test preparation

　　⒈Remove the sieve,place it from bottom to top according to the pore size,and place the weighed asphalt mixture sample into the top sieve.

　　⒉Put the whole set of screen on the funnel of the vibration frame,cover the spray cover and tighten the bolts.

　　压Press the weighed centrifugal cup into the centrifugal cylinder,cover the centrifugal cover,place the vibrator support,tighten the handle,and insert the guide tube into the middle hole of the centrifugal cover.

　　Calculation of the four oil-stone ratio

　　The total mass of the mineral in the asphalt mixture consists of two parts.

　　mα=m1+m2

　　In the formula:mα-total mass of the mineral in the asphalt mixture(g)

　　m1-mass of dried aggregates poured out of the screen(g)

　　m2－Increment before and after centrifugal cup filter paper 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 minerals.

　　mb=m－mα

　　In the formula:mb-asphalt quality in asphalt mixture(g)

　　m－Total mass of asphalt mixture(g)

　　mα－Total mass of the asphalt mixture(g)

　　The oil-stone ratio of the asphalt mixture can be obtained by the following formula:

　　pα=m－mα/mα×**

　　In the formula:petroleum ratio of pα-asphalt mixture(%)

　　全自动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中偏移，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。

　　Precautions for using the automatic asphalt extractor

　　★When the automatic bitumen content rapid extraction instrument is in the process of extraction,when the extraction is interrupted due to a power outage,it cannot be started 2 times with a load,otherwise it will be caused by the mineral powder,asphalt and trichloroethylene mixed solution in the centrifuge cup.The middle offset will damage the centrifuge tube,so the extraction power failure,the sample and the centrifuge cup must be cleaned and restarted according to the new test.

　　★During long-distance transportation,special attention should be paid to anti-vibration.The instruments and equipment should be packed in special packaging boxes.The inside of the boxes should be filled with plastic foam or soft paper.To ensure the appearance of the instrument is beautiful and the function is intact.

　　★If the instrument is not used for more than two days,the asphalt in the evaporation tank,the trichloroethylene mixed solution and the trichloroethylene in the solvent tank are released and stored in a special sealed plastic cylinder to prevent corrosion of the instrument.

　　★The seal ring of the two parts of the centrifuge tube and the top cover of the centrifuge is coated with petroleum jelly once every time.

　　★Due to improper installation or use of equipment,or failure of the equipment,the test cannot be performed normally.If the instrument is severely damaged,it must be submitted to the relevant personnel for repair.
