Automatic Distillation Unit ASTM D86 Distillation Test Equipment

I.Applicable Standards and Scope

This instrument is used for determination of distillation range of petroleum products according to the test method in GB/T 6536, complying with ASTM D86 and IP123. This instrument will automatically control the heating process and distillation speed, as well as record and print all record data.

Characteristics of the Instrument

(1) Automatically controlling of test process. 10" touch LCD for display of temperature, volume and curves during the whole process.

(2) Level tracking system consists of American Haydon high-stepping linear motor, imported integral linear ball screw circumferential positioning laser tracker (Japan KEYENCE). The cooling tube and cylinder room are refrigerated mechanically; imported Danfoss (Secop) compressor. Circulate in the cooling medium. Check and add cooling water every 2 years.

(3) Automatically heating control of distillation over, the sample can be heated to 95% of the flow rate from initial boiling point controlled within 4~5ml per minute.

(4) Provide initial boiling point and final boiling point temperature, and various percentage temperature and flow rate.

(5) Automatically measuring of local atmospheric pressure, and corrected to standard atmospheric pressure.

(6) Stopping of test by the steam temperature available.

(7) The test result can be stored, queried and printed.

III.Operating Principle

This simulated distillation device consists of automatic bath/distillation temperature control system, refrigeration system, automatic level tracking system, security system and other components. The instrument adopts multi-thread operation and control, to achieve automated operation, control, computing and display, improving intelligent and automatic measuring. This instrument adopts fuzzy temperature control principle. A freon compressor is used in the refrigeration equipment for temperature control for precise control of condenser and receive chamber temperature. The temperature measurement system adopts high-precision heat resistance for precise measuring of steam temperature. This instrument adopts imported high-precision level tracking system for precise measuring of distillation volume with accuracy of 0.1ml.

IV.Instrument Installation4.1 Accessory Inspection

After unpacking, please check the type, specification and quantity of accessories of the instrument according to the packing list.

Note: 1. Open the instrument packing case, and check the instrument for damage;

2. Check the instrument type and accessories according to the packing list.

4.2 Instrument Installation

1. Position requirement

1. The instrument shall be placed on a flat, clean, dust-free workbench surface.

2. The instrument shall be placed in a position without obvious vibration.

3. The position where the instrument is placed shall be kept away from the place where harmful gas or liquid drops exist.

4. Make sure the positions where the power cord pass are not exposed to high temperature or frictional objects.

2. Starting method

1. Open the instrument packing case, and check the instrument for damage.

2. Check the instrument type and accessories according to the packing list and inspect the working state of the instrument, making it be in line with the working environment and conditions, stipulated in the instruction book.

3. Debug the instrument only if the instrument has no errors after inspection.

4. Put the instrument on the experiment tabletop stably and adjust the horizontal feet until the horizontal bubbles are located in the middle of the circle; plug the power cord into the AC220V instrument three-pin socket; must keep the instrument in a good grounding condition.

Method for adjusting the horizontal feet: firstly, adjust four horizontal feet to the lowest position along the clockwise direction; observe the inclination direction of the horizontal bubbles; and adjust the height of the horizontal feet until the horizontal bubbles are located at the center of the circle.

5. Connect the data cable of printer to the RS232 serial port cable at the back of the instrument and power on the 7.5V power supply.

6. When everything is ready, power on by turning on the power switch of the instrument.
