Safety Low High Temperature Testing Thermal Shock Tester Customized

1. Description:

Three-Zone High-Low Temperature Thermal Shock Environmental Test Chamber occurs when a thermal gradient causes different parts of an object to expand by different amounts. This differential expansion can be understood in terms of stress or of strain, equivalently. At some point, this stress can exceed the strength of the material, causing a crack to form. If nothing stops this crack from propagating through the material, it will cause the object's structure to fail.

 2.the air conditioning system
.   the air control: forced ventilation circulation, balance thermostat method (BTC). This method not only refers to the case of the cooling system for continuous operation, the control system according to the temperature set point of the heater to control the output of the results by automatically calculating PID output, and ultimately achieve a dynamic equilibrium.
.   the air circulating means: built between the air circulation fan duct and the long axis of stainless steel, the use of energy efficient refrigerators and regulation system, by effective and efficient heat exchange ventilator, to achieve the purpose of the temperature change. By adjustable air outlet adjusting bolt, thereby significantly improving the chamber temperature uniformity;
.   the air cooling method: multi-stage diaphragm air heat exchanger.
.   the air heating: Watkins quality nickel chrome electric heater.

3. Specifications of Three-Zone High-Low Temperature Thermal Shock Test Chamber:

8.Thermal Shock Chambers maintenance actions

.  a reasonable choice of installation location to install measures: dry, non-drip of rain and snow place.

.  inspection measures qualified by hand daily for insulation materials is broken steam pipe is blocked for technical confirmation and disposal technology.

.  the alarm can be installed as conditional steam leak or power-off state of alarm sound and light small device to facilitate the holding of risk freezing measures discovery and timely remediation.

.  instrument maintenance inspection measures by the area responsible for regular inspection by a predetermined inspection route. To check the insulation inspection of pipeline valve is normal, the incubator is normal, hydrophobic means is normal, thermal insulation material packaging is intact, electric heating power supply and other components is normal.
