Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
As shown in fig. 1 and 2, a liquid tank impact test chamber comprises a test chamber body 1, wherein a working chamber 1a is arranged at the upper part of the test chamber body 1, and a unit chamber 1b is arranged at the lower part of the test chamber body 1, wherein a high-temperature liquid tank 2 and a low-temperature liquid tank 3 are arranged in the working chamber 1a, and the upper ends of the high-temperature liquid tank 2 and the low-temperature liquid tank 3 are open and are used for containing liquid media. A heating device 2a is installed in the high-temperature liquid tank 2 for heating the liquid medium, and a refrigerating device 3a is installed in the low-temperature liquid tank 3 for cooling the liquid medium. A lifting rod 4 is arranged between the high-temperature liquid tank 2 and the low-temperature liquid tank 3, a lifting cylinder 4a is arranged at the bottom of the lifting rod 4, and the lifting cylinder 4a is fixed in the unit chamber 1 b.
