The high-low temperature impact test box is a necessary test equipment for metal, plastics, rubber, electronics and other materials industries. It is used to test the structure of materials or composite materials, and can tolerate it under extremely high temperature and extremely low temperature in a continuous environment. The chemical change or physical damage caused by thermal expansion and contraction of the sample can be detected in the shortest time.
The structure of high-low temperature impact test chamber equipment usually has three forms: single box type, vertical lift type and horizontal two box type. Single box type due to the required amount of cooling capacity and the amount of large, this type of structural feasibility is poor, practical application is very small; vertical lift type through the internal lift conversion, to avoid the impact of the external environment, but due to the lifting device itself As a heat load to consume cooling or heat, so this method is usually suitable for small test chambers, for medium and large test chambers, due to the lifting device is too heavy, this approach does not apply, horizontal two boxes through the mutual between the two boxes The conversion reduces the load on the cabinet to reduce the cooling and heating of the equipment, but it requires a horizontal conversion device and is affected by the external environment.
Therefore, the choice of test methods should be analyzed in accordance with specific conditions. For small equipment, using a vertical lifting method will save one box, which can save costs; but for medium and large-scale high-low temperature impact test boxes, as long as the program is reasonable and feasible, it can guarantee To meet the requirements of the national military standard, the use of a horizontal two-box test program is a better choice.
The following is a brief understanding of the maintenance methods for high and low temperature impact test chambers:
1. High-low temperature impact test box The professional electrician periodically replaces the carbon brush for the impact drill and checks the spring pressure.
2. Add the body screw fasteners that are lost on the body during operation.
3, high and low temperature impact test box regularly check the transmission part of the bearings, gears and cooling fan is flexible and in good condition, timely rotation of 4 parts plus oil, in order to extend the life of hand drill.
5, to ensure that the overall impact of the drill body is intact and clean and dirt removal, to ensure that the impact of electric drill to move smoothly.
6, high and low temperature impact test box by professionals regularly check the hand drill parts are damaged, the serious damage can not be reused should be promptly replaced.
7. After the high-low-temperature impact test box is used, the hand drill should be promptly returned to the tool library for safekeeping. Eliminate overnight storage in personal tool cabinets.
Hengtai Fengke Tips 1. High-temperature scald, high-low temperature impact test chamber When the high temperature test is done, the temperature in the chamber is high. During the test or at the end of the test, if you need to open the box, be careful when you open the door. Remember to walk in the direction that they are open to avoid burns.
2, low temperature frostbite, high and low temperature impact test box in the low temperature test when the box temperature is very low. During the test or just after the test, be careful to open the door to avoid frostbite.
