Product Description

The system structure of the cold and hot impact test chamber is divided into high temperature tank (preheating zone) and low temperature tank (precooling zone). The sample is placed in the test zone. During the impact, the temperature of the high temperature zone or low temperature zone is driven into the test zone by the high pressure cylinder for temperature impact, so as to achieve the purpose of drastic temperature change. The test product is static. This test chamber is applicable to assess the ability of complete machine products, components, parts, materials, etc. to withstand sharp temperature changes. This temperature impact test is used to evaluate the test sample caused by thermal expansion and contraction in the shortest time

Purpose The system structure of the cold and hot impact test chamber is divided into high temperature tank (preheating zone) and low temperature tank (precooling zone). Some samples are placed in the test zone, and the temperature of the high temperature zone or low temperature zone during impact passes

 

The high pressure cylinder drives into the test area for temperature impact, so as to achieve the purpose of drastic temperature change. The test product is static. This test chamber is applicable to assess the ability of complete machine products, components, parts, materials, etc. to withstand sharp temperature changes. This temperature impact test is used to evaluate the test sample due to thermal expansion and contraction in the shortest time

 

The chemical change or physical injury caused by the temperature change can be understood. The main parameters affecting the temperature change test are the high and low temperature values of the temperature change range, the holding time of the test sample at high and low temperatures, and the number of cycles of the test.
