Embodiment 1

[0044] Please refer to the attached figure 1 , a cold and heat impact system, comprising an air intake system 1, the compressed air pipeline 11 of the intake system 1 is fed with compressed air 14 with a pressure of 70psi-130psi high pressure, preferably air with a pressure of 90psi-110psi, and compressed air The pipeline 11 is connected with an air treatment system 2. The air treatment system 2 includes an oil dust filter 21 and a dry air generator 22 connected in sequence. The oil dust filter 21 includes a dust filter 211 and an oil filter 212, respectively. The oil and dust in the air are filtered to ensure the removal of impurities in the air, and a dry air generator 22 is further installed. The dry air generator 22 is used to remove water droplets in the air, so that the compressed air 14 is fully dried.

[0045] Based on the above settings, an air pressure gauge 12 and an air pressure switch 13 are connected to the air inlet of the compressed air pipeline 11. The air pre...

Abstract

A thermal shock system and a thermal shock machine provided with the system are provided and overcome the problem that temperature rising and lowering are slow and energy consumption is high in present thermal shock systems. According to a technical scheme, the thermal shock system includes a gas feeding system a compressed air pipeline of which is fed with compressed air having pressure of 70-130 psi; a cooling system connected to the gas feeding system and outputting cooling gas the temperature of which is -80 DEG C or above; a heating system into which the cooling gas is fed and which outputs impact gas having a temperature of -80 DEG C to 225 DEG C; an air processing system communicated with the compressed air pipeline of the gas feeding system so as to purify the compressed air; and a control system used for controlling start and stop of the cooling system and / or the heating system to allow the temperature of gas ejected to be a temperature preset value input by a user, thus achieving rapid temperature lowering and temperature rising, avoiding pre-heating and pre-cooling and avoiding liquid nitrogen assistance. The thermal shock system also has an advantage of greatly reduced energy consumption, thus reducing the cost.

Description

technical field [0001] The present invention relates to a kind of testing mechanical equipment, especially to a kind of test material structure or composite material, which can withstand the continuous environment of extremely high temperature and low temperature in an instant, so as to test its thermal expansion and cooling in the shortest time. Thermal shock tester for chemical or physical changes caused by shrinkage. Background technique [0002] Impact testing machine is the necessary testing equipment for metal, plastic, rubber, electronics, semiconductor, IC, communication and other material industries. To a certain extent, it is possible to detect the chemical change or physical damage of the sample caused by thermal expansion and contraction in the shortest time. [0003] The main technical parameters of the cold and heat shock test equipment in the prior art are: ① Temperature range: -65°C to 100°C (actual effect: -40°C to 100°C); ②Temperature recovery time: 5min; ...
