A Brief Comment on the Use and Working Principle of High and Low Temperature Test Chamber

As the core equipment in environmental test equipment, high and low temperature test chambers are used in various fields. Its working principle is mainly controlled by its refrigeration unit. Through the control panel, customers can set test requirements and simulate the real environment to achieve the test effect.

1. Use of high and low temperature environmental test chamber

High and low temperature test chamber: This instrument is suitable for high and low temperature reliability tests of industrial products. For the components and materials of electronic products, automobile motorcycles, aerospace, marine weapons, colleges and universities, scientific research units and other related products under high and low temperature (alternating) cycle changes, check each performance index. The product has a wide temperature control range, and its performance indicators have reached the national standard GB10592-89 high and low temperature test chamber technical conditions, which is applicable to the environmental test of electrical and electronic products A: Low temperature test method and test B: High temperature test method "conducts low temperature, high temperature test and constant temperature test on the product. Products comply with GB2423.1, GB2423.2, GJB150.3, GJB150.4, IEC, MIL standards.

3. Working principle of high and low temperature test chamber

Refrigeration working principle: The refrigeration cycle adopts the reverse Karo cycle, which consists of two isothermal processes and two adiabatic processes. The process is as follows: the refrigerant is adiabatically compressed by the compressor to a higher pressure, and the consumed power makes the exhaust After the temperature rises, the refrigerant exchanges heat isothermally with the surrounding medium through the condenser to transfer the heat to the surrounding medium. After the refrigerant passes through the shut-off valve for adiabatic expansion to do work, the refrigerant temperature decreases. Finally, the refrigerant absorbs heat isothermally from the object with a higher temperature through the evaporator, thereby lowering the temperature of the object to be cooled. This cycle is repeated to achieve the purpose of cooling. The refrigeration system of this test chamber uses a unit Freon refrigeration system composed of a French-made Taikang fully enclosed compressor. The design of the refrigeration system uses energy adjustment technology, which can not only ensure the normal operation of the refrigeration unit, but also effectively adjust the energy consumption and cooling capacity of the refrigeration system to keep the refrigeration system in the optimal operating state. The use of balanced temperature regulation (BTC), both in the case of continuous operation of the refrigeration system, the control system automatically calculates the output of the PID according to the set temperature point to control the output of the heater, and finally reaches a dynamic balance.

Twist Rope

Product Features

 The twisted rope consists of three strands and is normally right-laid, or given a right-handed twist,including PP Rope, polyester rope, nylon rope, sisal rope and so on.

 

This rope has a balanced construction, medium lay and moderate stretch. A tough twisted construction makes this rope strong, yet easy to splice and also prevents it from unwinding.
