The viscosity measurement system is a specialized, automated testing device designed for the characteristic viscosity, viscosity number, average molecular weight, and viscosity average molecular weight of polymers. Depending on the number of test units configured in the system, it is divided into NCY-X/2, NCY-X/4, and NCY-X/6 models, each with corresponding configurations of two, four, or six test units, allowing for the simultaneous use of two, four, or six viscometers.

UtilizeNcy-xViscosity Automatic Measurement System Ahead:

The measurement of the time required for a certain amount of solution to flow through a capillary, originally performed manually.

The original determination of data validity, which was previously done manually,

Like the NCY Automatic Viscosity Meter, it will still be executed by the system.

The system will still display the solution flow in capillary viscometers within each unit in real-time and vividly.

The system will still automatically repeat testing and eliminate out-of-tolerance results to obtain accurate flow time.

The system still features the JWC precision temperature-controlled bath, a result of our 1990s national research project, and continues to deliver long-term temperature fluctuations and distribution accuracy better than ±0.01℃. This ensures consistency in test data at any time and location.

In addition, the automatic testing system will also feature the following new functions:

Automated liquid preparation instrument with precision up to 0.1%, capable of conveniently preparing sample solutions (one-button liquid preparation).

A double-glazed isolation design of the sample bottle ensures that the prepared solution can dissolve quickly and evenly in a precise恒温 oscillator bath without interference from moisture.

Automatic liquid delivery system, no longer requiring manual feeding of the viscosity tube, a comprehensive unit that automatically filters and delivers the solution into the capillary of the viscometer.

The automatic test has concluded. The system will automatically extract waste fluid and await the arrival of the next sample to automatically complete the capillary rinsing and testing.

When cleaning capillaries is required, simply activate the cleaning program, and the system will autonomously complete the entire process of washing fluid injection, soaking, recovery, cleaning, and drying, without the need for manual intervention.

2. Layout of the automatic viscosity measurement system

This automated testing system is composed of several components, which can be arranged in various configurations according to the user's setup, but its fundamental principle is:

2.1 Ensure all pipe distances are as short as possible, while also considering actual operations such as filling and emptying. The cover image illustrates a typical reasonable layout.

2.2 The pipeline from the central control unit to the viscometer must only slope downwards from the central control system, without any upward slopes in between.

3. Sample Handling

3.1 Automatic Solution Preparation

See PY Automated Mixture Dispenser manual (optional accessories).

3.2 Quick Dissolution of Samples

See WR-2 Rapid Sample Dissolution Oscillator manual (accessory), equipped with a double-layer sleeve dissolution bottle.

The dissolution process of the sample in the solvent can sometimes be quite lengthy, taking one, even more, hours. It requires oscillation at as high a temperature as possible to accelerate the process. Excessive temperature will lead to degradation, so the temperature should be precisely controlled.

4. Vacuum Pressure Adjustment

The automatic testing system operates under the action of vacuum pressure. This system is equipped with different pressure sources specifically for the liquid supply and testing of the viscometer, transmission of washing liquid, and drying. Different vacuum pressures need to be adjusted according to the solvent composition of the samples and washing liquids to accommodate.

Vacuum pressure adjustment method:

Two pressure gauges are located on the control system panel: the constant pressure gauge adjusts and controls the working pressure of the sample solution, while the pump pressure gauge adjusts and controls the working pressure of the wash liquid.

Vacuum pressure regulation methods are as follows:

Press the pattern key (left button), until "L" appears0-2, shows the lower limit of the current vacuum setting. Press the up and down keys to adjust the upper limit setting.

Press the mode key again to display H1-2 shows the current upper limit of vacuum degree. Press the up and down keys to adjust the upper limit setting.

Note, the vacuum pressure value is negative.

5. Liquid Inlet and Testing

Prepare a clean empty solvent sample bottle, remove the solvent bottle containing the dissolved sample from the oscillator, pour half of its contents into the empty solvent bottle, and place them together in the corresponding sampling unit position.

During testing, only approximately 13mL of sample is required. Therefore, if it's necessary to rinse before testing, you'll need to prepare about 26mL of solution at a time. Place the dissolution vial on the autosampler, hold down the rinse key for the corresponding module, and the dissolution vial holder will advance. Stop when the previous dissolution vial (for rinsing) is at the liquid tube position. The liquid tube will then lower and insert into the volumetric flask, while the volumetric flask for the test sample is automatically capped. After starting the test, the testing system will automatically draw the solution from the dissolution vial, complete the rinse, and automatically drain the liquid.

Keep holding the test button, another sample vial is sent to the testing station, waiting for the test to start. Test complete, the sample vial returns to the starting position.

Sample Bottle Location

Washing Position: The suction tube is inserted into a solvent bottle in front, and the mouth of the subsequent solvent bottle is automatically sealed.

Test Port: Insert the syringe into the vial at the back.

Test completed, solvent bottle returned to starting position.

After initiating the test program for this unit on the computer, the unit automatically enters the working state. The subsequent operations are performed automatically by the system. The operator can view the progress of the unit's testing on the screen, and a dialog box will automatically pop up if any issues arise during the test.

Test completed; after the system automatically discharges the waste fluid, it proceeds to the next test phase.

6. Capillary Viscometer Cleaning and Drying

Viscometers should be cleaned after being used for a period of time.

First, place a solvent sample bottle in the rinse position (or test position) of the sampler, and the pipette will automatically insert into the bottom of the bottle (this is very important!!)

Check and ensure there is an adequate supply of detergents, solvents, and potable water. Verify that containers for waste liquids and wastewater have sufficient remaining space.

Then you can start and complete the full cleaning-drying process.

Select "Wash Solution Immersion Cleaning" on the computer interface, and the viscometer can complete the entire cleaning-drying process.

7. Routine Maintenance

7.1 Liquid Storage Bottle

Storage bottles require regular monitoring of the liquid level. For waste liquid collection, timely cleaning is necessary when the level is high; for new liquid types, it is important to replenish promptly.

Remove the cap with care, noting the original state. Some may have a layer of polytetrafluoroethylene film attached to prevent corrosion. When reinserting the plastic tube, be sure to pay attention to the tube's numbering and the corresponding entrance marked on the label. When replacing the cap, ensure it is tightly sealed and note the seal.

7.2 Vacuum Pump

This type of vacuum pump, if the suction port maintains a vacuum (low pressure), may cause oil to spray from the suction port outward. The machine has been equipped with a special program in the control system to prevent oil spraying. However, after a considerable period of use, the oil level may decrease. When the oil level in the pump side oil indicator falls below "min," add vacuum pump oil to the space between the first and second scale lines on the indicator.
