Description

TECHNICAL FIELD

[0001] The utility model relates to viscosity meter calibration technical field, especially a kind of full-automatic timing device for calibration of Saybolt heavy oil viscosity meter. BACKGROUND

[0002] Saybolt heavy oil viscosity meter is a practical viscosity meter, mainly used to determine the Saybolt viscosity of asphalt or heavy oil under certain constant temperature conditions. It can be used to determine the construction temperature of asphalt, and evaluate the fluidity of petroleum products. The working principle of Saybolt heavy oil viscosity meter is based on the time required for oil at a certain temperature to flow through a fine hole to measure viscosity. Specifically, it measures the time for a certain amount of oil to flow through a fine hole at a certain temperature, which is measured in seconds and called Saybolt seconds. The length of this time directly reflects the viscosity of the oil, the longer the time, the higher the viscosity. Saybolt heavy oil viscosity meter mainly consists of bath, bath temperature controller, determination parameter display calculator (calibration coefficient, time, viscosity, etc.). The specific operation is as follows: 1. Prepare asphalt sample and heat it to the specified test temperature; 2. Heat the water or oil in the holding tank and maintain the specified test temperature; 3. Calibrate the viscosity meter to ensure its accuracy; 4. Inject the sample into the sample tube and make it reach the specified test temperature; 5. Pull out the cork at the bottom of the sample tube, and press the stopwatch at the same time to record the time of the sample flowing into the receiving bottle; 6. Calculate the Saybolt viscosity of the sample according to the recorded time and the calibration coefficient of the viscosity meter. About the calibration of viscosity meter: the viscosity meter should be recalibrated once in no more than 3 years; the calibration method is as follows:

[0003] 1. Test the viscosity measured by Saybolt heavy oil viscosity meter at 50℃.

[0004] 2. If the flow time of standard viscosity oil measured by viscosity meter (not less than 90s) differs by more than 0.2% from the standard flow time provided in the viscosity meter instruction manual, the measured time should be corrected according to the calibration coefficient calculated by formula (T0623-1); when the error exceeds 1%, the instrument cannot be used.

[0005]

[0006] In the formula: F is the calibration coefficient;

[0007] t1 is the standard flow time provided by the viscosity meter (s);

[0008] t is the actual flow time of the same standard viscosity oil at 50℃ (s).

[0009] For the above related technology, the inventor finds that when calibrating the viscosimeter, the cork blocking the bottom of the sample tube is pulled out, and the stopwatch is pressed at the same time to record the time of the sample flowing into the receiving bottle, and since the operator's action has a long delay, the time record of the sample flowing into the receiving bottle also has a large error, which reduces the calibration accuracy.
