[0002] Viscosity is a physical quantity that measures the viscosity of a fluid. It is a measure of the internal friction between molecules when a liquid moves under the action of an external force. The viscosity of a fluid is closely related to the processing, production, and use of materials, especially in the fields of petroleum, chemical industry, light industry, coal, metallurgy, transportation, national defense, aerospace, etc. Energetic materials, as a special type of chemical material, also have a viscosity characteristic that has an important impact on their processing, storage, and use.

[0032] When the liquid level in the test funnel detected by the liquid level sensor reaches the closing liquid level, the solenoid valve is closed to stop the energetic material in the test funnel from flowing out, and at the same time, the timing unit stops timing to obtain the outflow time.

[0033] The beneficial effects of the present invention are:

[0034] After the material cup is loaded with the energetic material, it can be transferred to the oil bath dissolution device and the oil bath insulation device in sequence by the truss transfer device to dissolve the energetic material and adjust it to the test temperature, and then pour the energetic material in the material cup into the test funnel; in addition, under the liquid level detection action of the liquid level sensor, the energetic material in the test funnel flows out from the starting liquid level to the closing liquid level, and the timing unit records the outflow time, thereby facilitating the calculation of the viscosity of the energetic material; in summary, the energetic material viscosity testing system can test the viscosity of the energetic material.
