Description

Three-in-one petroleum product testing device

Technical Field

The utility model relates to a testing device, in particular to a three-in-one petroleum product testing device.

Background

In the physical property test of petroleum products, density, kinematic viscosity and viscosity index are important parameters for testing the physical properties of various different petroleum products.

In the detection practice, the meanings of the three parameters are different, so that the detection method and the detection requirement are different.

Density refers to the mass of liquid per unit volume. The density is measured by a densitometer: the sample is loaded into a defined densitometer cylinder and a suitable densitometer is placed into the sample. The density measuring cylinder is fixed on a constant temperature bathtub cover by a proper method, and the test part of the density measuring cylinder is placed into a constant temperature water bath with a certain test temperature and a temperature control precision of +/-0.25 ℃ for measurement. Here, the densitometer has certain requirements on the diameter, depth and fixing mode of the densitometer.

The density test results were: the arithmetic average of two consecutive measurement results under the same conditions was taken as the density of the sample.

Kinematic viscosity refers to the resistance of an oil to flow under the force of gravity. The detection of the kinematic viscosity is a method measured by a capillary viscometer: the sample is put into a capillary viscometer, and the capillary viscometer is fixed on a constant temperature bathtub cover by a proper method, so that the test part of the capillary viscometer is put into a constant temperature water bath with a certain test temperature and a temperature control precision of +/-0.1 ℃ for measurement. Here, the capillary viscometer has certain requirements on the diameter and depth of the constant-temperature water bath and the fixing mode of the capillary viscometer.

The kinematic viscosity test results were: the arithmetic average of the two results of the repeated measurement under the same conditions was taken as the kinematic viscosity of the sample.

Viscosity index refers to the value of the kinematic viscosity of petroleum products as a function of temperature. The method for detecting the viscosity index is a method for measuring the kinematic viscosity, and is different in that the kinematic viscosity values at 40 ℃ and 100 ℃ are measured respectively to obtain the viscosity index values, and then the viscosity index values are calculated through a formula.

The detection of density and kinematic viscosity (viscosity index) belongs to two different physical property detection, so that the detection consideration of the three parameters is concentrated on the same instrument. Currently, there are three different physical property tests, two different instruments. Firstly, an instrument special for detecting density; secondly, the instrument for detecting the kinematic viscosity is used for detecting the viscosity index, but the calculation of the viscosity index needs manual calculation, and the workload is large and complicated.

At present, two different instruments are needed for detection, and the commonality and the integration level of the instruments are poor.

2. In the detection of the viscosity index, the measurement of the kinematic viscosity adopts a manual mode of a capillary viscometer, and after the kinematic viscosity value at 40 ℃ and 100 ℃ is obtained, the viscosity index value is calculated by a manual calculation mode, so that the calculation workload is large.

3. In order to meet the measurement of the three parameters, the units of petroleum product production, use, research and the like need to purchase instruments with two specifications, and more purchase funds need to be paid.

4. In the situation of multiple instrument varieties, more manufacturing materials, more components and parts are required to be consumed, more labor is required to be invested, the material cost and the labor cost for instrument manufacturing are increased, and the national policy of energy conservation and emission reduction is not met.
