Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a heating system for an oil bath impact sensitivity meter. Background Technology

[0002] Energetic materials are not only key materials in advanced weaponry, but also important energy sources for industrial and transportation construction, as well as aerospace launch systems. High-nitrogen energetic compounds have become a research hotspot in the field of high-energy-density materials in recent years due to their high density, high heat of formation, high stability, and environmental friendliness. Energy and safety have always been the two most concerned aspects in the development of energetic materials. Energy can be represented by reaction heat, detonation velocity, pressure, and work capacity, while safety is assessed by the sensitivity of energetic materials to external stimuli. The higher the sensitivity, the lower the safety. Existing impact sensitivity testers can only measure the impact sensitivity of energetic materials at room temperature, and cannot simulate different temperatures. They are not applicable to temperature-sensitive reaction scenarios and have a narrow range of use, which affects the test results. Utility Model Content

Detailed Implementation

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings. Example

[0024] like Figures 1-4 As shown, an oil bath impact sensitivity meter heating system includes a mounting bracket 1, an oil bath container 2 disposed below the mounting bracket 1, a firing device 3 disposed above the oil bath container 2, and a heating module 4 disposed on one side of the mounting bracket 1. The heating module 4 includes a heating controller 41 and a heating oil bath box 42. The heating oil bath box 42 contains a heating wire, a circulation pump, and crude oil. The heating controller 41 is electrically connected to the heating wire and circulation pump in the heating oil bath box 42. An oil circulation pipe 5 is provided between the heating oil bath box 42 and the oil bath container 2, and the circulation pump is connected to the oil circulation pipe 5.

[0025] The working principle of the above technical solution is as follows:

[0026] A heating controller 41 and a heating oil bath 42 are added to the sensitivity meter. The heating controller 41 controls the heating wire in the heating oil bath 42 to heat the crude oil inside. The heated crude oil enters the oil circulation pipe 5 through the circulation pump and then enters the oil bath container 2 below the firing device 3. According to different impact experiments, the temperature and volume of the crude oil in the oil bath container 2 can be flexibly adjusted to provide the high-temperature environment simulation required for the impact experiment. Dynamic temperature adjustment can even be achieved to more accurately simulate experimental conditions. This oil bath heating system can achieve high-precision temperature control at the ±0.1℃ level through circulating hot oil, which can avoid thermal fluctuations and ensure the stability of temperature conditions during the experiment. Moreover, the constant oil bath temperature can eliminate the interference of external ambient temperature changes on the experiment and ensure the consistency of experimental conditions in multiple experiments.

[0027] The oil bath container 2 comprises an inner layer 21, a middle layer 22, and an outer layer 23 arranged coaxially with gradually increasing outer diameters. The space formed by the inner layer 21 and the middle layer 22 is the oil bath heating chamber, and the space formed by the middle layer 22 and the outer layer 23 is the heat insulation chamber. The oil circulation pipe 5 extends into the oil bath heating chamber. This multi-layered structure provides the required experimental temperature for the firing experiment through the oil bath heating chamber. Simultaneously, the oil bath heating chamber is independent of the inner layer space, preventing oil contamination of the firing device or sensor, thus improving the accuracy and reliability of the experiment. The middle layer 22 and the outer layer 23 form a heat insulation layer, which insulates the oil bath heating chamber, ensuring a stable experimental temperature and reducing the risk of localized overheating caused by direct contact between the heating element and the sample.

[0028] The oil bath container 2 has a built-in temperature sensor 6, and a cover plate 24 is installed on the oil bath container 2. A strike sensor 7 is installed in the center of the cover plate 24, and a pressure sensor 8 is installed on the surface of the cover plate 24. The cover plate 24 is slidably connected to the oil bath container 2 to ensure reliable sealing. At the same time, the controller 41 is connected to the oil circulation pipe 5, the temperature sensor 6, the strike sensor 7, and the pressure sensor 8. The heating oil bath box 42 is an explosion-proof box. Through the cooperation of multiple sensors and the explosion-proof box, the reliability and safety of the experiment can be ensured.

[0029] A storage rack 9 is provided on one side of the heating module 4, which can be used to place spare oil bath containers, including oil bath containers for friction sensitivity and oil bath containers for impact sensitivity. The selection can be made flexibly according to the experimental object, improving the flexibility and convenience of the experiment.

[0030] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
