Low pressure simulates outer space environmental climate
The high and low temperature and low pressure test chamber is mainly used in aerospace information electronics and other fields to determine the performance of instruments, electrical products, materials, parts and equipment under the single or simultaneous action of low pressure, high temperature and low temperature. The environmental adaptability and reliability test may be conducted simultaneously with the test piece being energized to measure electrical performance parameters.
Forced air blast balances the temperature and creates speed
Adopts the rear side air duct forced air circulation to supply air through the upper side window
The air in the working room moves in a turbulent flow manner to meet the requirement of uniform temperature Requirements for degree
The motor is installed outside the vacuum chamber and introduced into the vacuum chamber through the long axis and drives the rotation of the centrifugal wind wheel
The combined structure is scientifically designed with super functions
The test chamber adopts an integral combined structure form and is located in The insulation box at the front is composed of a refrigeration vacuum unit at the rear and an electrical controller located on the door of the test chamber
The electrical control panel is placed on the front door of the test chamber for easy operation
Vacuum system composition< br/> The vacuum system is an integral part of obtaining the vacuum degree and measuring and controlling the vacuum degree. It is composed of a vacuum measurement system and a vacuum acquisition unit
The vacuum pump is a direct-coupled rotary vane vacuum pump produced by a Shanghai company
Note that this equipment is The temperature, humidity and negative pressure dimensions of non-standard customized products can be customized according to customer requirements.
The product will be delivered to your door and professional engineers will be arranged to install and debug it.
