SYD-265E Petroleum Kinematic Viscosity TesterCircuit principle:

The instrument consists of a capillary viscometer, mercury thermometer, electric stirring device, electric heating device, temperature controller, double-layer constant temperature bath, and lighting lamp. The structural diagram is shown in Figure 1, and the electrical schematic diagram is shown in Figure 2. The main features are:

1Double layer constant temperature bath: The inner layer adopts a hard glass cylinder with a diameter of 300 × 300mm, and the outer insulation sleeve is an organic glass cylinder with a diameter of 360 × 285mm. There is an air insulation layer between the inner and outer layers. During the test, in order to prevent water vapor from entering the insulation layer and affecting the observation, dry air can be filled into the insulation layer (the filling equipment is provided by oneself). There are four holes on the bathtub cover, which are used to place capillary viscometer clips and adhesive wood covers. There are three adjustment screws installed on the clamp to adjust the verticality of the capillary viscometer.

2The lighting adopts a 220V 16W2D fluorescent lamp, which provides a guarantee for clear observation of the readings of the capillary viscometer.

3Temperature controller:

⑴ Temperature sensor: Industrial platinum resistance, with a division number of Pt100.

⑵ Temperature controller: Intelligent temperature controller with PID self-tuning and four position dual LED window indication function, fast temperature control, fast response, small overshoot, and temperature control accuracy of ± 0.1 ℃.

⑶ Heating system: 1000W and 600W dual electric heating tubes for heating. At the beginning of the instrument's operation, 1000W auxiliary heating and 600W temperature controlled heating are used together to heat up quickly; Near the set observation temperature point, the heating power can be automatically adjusted, with 1000W auxiliary heating turned off and only 600W temperature controlled heating working to ensure stable bath temperature.

4. Mixing system: The electric mixer is a single-phase asynchronous motor. The electric shaft and mixing shaft are isolated by epoxy rods, which will not affect the normal operation of the motor.

Working conditions for instrument use:

1The instrument should be placed in a dry, clean, and non corrosive gas environment, and should be placed on a flat and stable experimental platform.

2Methyl silicone oil or glycerol solution should be placed in the constant temperature bath.

3When testing the sample, an appropriate capillary viscometer should be selected according to the requirements of the experiment.

On site installation:

1Open the packaging box, count the spare parts, pay attention to glassware, especially capillary viscometers, and handle them gently. Do not forcefully pull or plug them to avoid damage.

2Fasten the plumb ball on the hook of the rubber wood cover, adjust the bottom corner screw of the chassis to make the cylinder wall parallel to the vertical line.

3Insert the thermometer and sensor into the corresponding holes of the cylinder head.

4Connect the eight pin plug socket at the back of the chassis to the cylinder head, connect the three pin plug of the sensor to the three pin socket of the chassis, and connect the four pin power cord to the four pin aviation socket.
