Combined Environmental Test System For Satellite Parts Vibration And Temperature Test

1. External Environmental Conditions

Ambient temperature: 0°C~35°C , RH: 85%,Ambient pressure: normal atmosphere

Power supply: 380V±10%,50Hz+N+G,RG: ≤4 Ohm

2. Main characteristics of temperature and humidity

► Temperature Range:-40℃～+150℃

► Temperature Constancy:≤ ±0.5°C

► Temperature Uniformity: ≤ 2℃；

► Temperature Deviation:≤ ±2°C

► Temperature rate of chang(Measured at 20±2°C of ambient temperature, averaged throughout)

Heating rate:+20℃→+150℃ ≥3℃/min；(No load, average throughout)

Cooling rate:+20℃→ -40℃ ≥2℃/min；(No load, average throughout)

► Humidity range:10%~98%( See below temperature and humidity range chart, no heat dissipation load)

► Humidity deviation: +2/-3±%RH( ＞ 75%RH) ±5.0%RH(Humidity ≤75%RH)

► Humidity uniformity:≤+2/-3%RH(＞75%RH时)≤±5%RH(≤75RH)

3. Main features of size

► Internal effective volume:about 2000L

► Inner size:1400 x 1400 x 1000mm (W x D x H)

► External dimensions of the chamber:about 3900 x 2400 x 2800 mm (W x D xH) (Subject to the final design)

► With the vibration table size:slip table≤1000 x 1000mm；Head Expander≤1000 x 1000mm

4. Refrigerating system

► The mechanical cooling is provided by a cascade system, which is realized by two advanced piston compressors. The main body is made of special cast iron, easy-to-integrate cylinder and light metal alloy piston.

The cooling system has an automatic compressor protection system, and an injection system can be used to protect the compressor during cooling from high temperatures. This system can self-regulate the cooling system of the compressor.

► Cooling method: air cooling.

► Refrigerant: Use environmentally friendly refrigerants R404A and R23 that are not prohibited by the Montreal Convention or the London Amendment and the new US Environmental Protection Agency law.

► Energy-saving adjustment mode: cold-end PID adjustment mode (that is, heating without cooling, cooling without heating), which saves about 30% of energy than the balanced temperature adjustment method. The cooling capacity can be adjusted intelligently, and it can be adjusted automatically according to the temperature state, so as to quickly realize the temperature change and temperature balance. Compared with ordinary heat and cold balance control, the temperature response speed is faster, the power consumption is lower, the temperature deviation and fluctuation in the box are smaller, and the temperature overshoot is effectively avoided

    ► Chamber bottom plate:

       Three special movable bottom plates are used to connect the chamber:

       One is the bottom plate with holes, which is used for vertical vibration;

       One is a bottom plate with a square hole, which is used when it is used with a horizontal slip table;

       A blind plate, used when not shaking.

       There is a condensate drain groove on the bottom of the shaker to prevent the condensate from flowing into the shaker.

► The fit of chamber and shaker

    With the head expander and with the slip table

 
 
Any special requirement please feel free to contact us, we will try our best to realize it.
 
 
Connection mode:
