The use of high and low temperature testing machines is the high temperature and low temperature reliability test of industrial products. It is very important for electronic and electrical, aerospace and some high-tech research institutions. Through the cyclic changes of high temperature and low temperature, the performance indexes of the tested products are tested. Compared with the constant temperature control system, the high and low temperature test chambers have a wider temperature control range, and the performance indexes are required to reach the national standard GB10592-89. Technical conditions of the low temperature test chamber.
Shanghai Bao test will be carefully explained: from the classification, high and low temperature alternating test chambers can be divided into alternating test and constant temperature test according to different test methods and industry standards. These two methods can be regarded as high and low temperature tests. The upgrade based on the box is expanded. The alternating test chamber can set the high temperature, low temperature and time required for the temperature to be within the instrument parameters. At this time, the high and low temperature test chamber will follow the set procedure, the temperature, humidity and other aspects inside. The situation is closer to the harsh natural climate, allowing for more scientific and objective detection of various parameters of the sample.
The quality of the high and low temperature alternating test machine is mainly determined by its temperature stability, temperature range, temperature uniformity and temperature deviation. The ultimate goal is to allow high and low temperature test chambers to better simulate the laws of temperature changes in the natural environment. Among them, the temperature uniformity can best reflect the quality of the test box. It mainly refers to the large value of the Zui between any two points in the working space at any time interval after the temperature is stable. The general standard is less than or equal to 2 degrees Celsius.
ZSQ series light Linear Vibrating Screen is a standard and universal Screening Equipment.The movement track of its screen box is close to straight line.Almost all the linear vibrating machine are consisted of the screen box,supporting or hanging device,driving unit, vibration isolation etc.
Linear screen uses double vibrating motors to drive,when two motors rotate synchronously and reversely, exciting forces generated by eccentric block are resolved in parallel to the direction of motor axis and then united as one across the motor axis direction,so its movement track is linear.There is an angle of inclination between the two motor axis relative to the screen deck.Under the influence of the resultant force of exciting force and materials itself weight,materials are thrown up to make leapfrog and linear movement forward on the screen deck in order to screen and grade the materiel . Applied in flowing line to achieve automatic operation.
