High altitude low pressure simulation test chamber

Box specifications:

1Internal dimensions:300(wide)×300(deep)×300(tall)mm；

2The internal dimensions are approximately:600(wide)×500(deep)×1200(tall)mmBased on the actual product;

3Layer: The inner box is divided into two layers, with two distribution boards;

4Visual window: Tempered glass visual window on the door,Visual window glass thickness19mm, specificationsW150*H150mm；

5Control panel: The operation panel is installed under the machine;(As shown in the figure)

6Installation of real pump: Vacuum is built into the lower part of the machine;

7The internal material is:304#Stainless steel industrial plate, with a thickness of3.0mmInternally strengthened processing, vacuum pumping without deformation;

8The outer material is cold-rolled steel plate,thick1.0mm,Powder baking paint treatment; (off white)

9Hollow filling material: rock wool, with good insulation effect;

10The sealing material at the entrance is: high-temperature resistant silicone strip;

11Machine structure: integrated type.

Vacuum system:

1The machine adopts high-density silicone sealing strips to ensure good sealing performance;

2Using Panasonic digital vacuum gauge to display the relative vacuum inside the box;(As shown in the figure)

3Vacuum holding timer. If the vacuum is reached and the holding timer needs to be controlled, simply turn on the timer. When the time is up, an alarm will be triggered. If not needed, it will be turned off;

4The vacuum control method is automatic control, which automatically stops when the vacuum reaches the set vacuum degree and starts automatically when it falls below the lower limit. This cycle works to achieve the desired vacuum degree;

5Pressure relief method: manual decompression after the test is completed or when taking the product;

6Range of machine vacuum degree:0to-100.0KPaThe vacuum degree varies depending on the region;

7Pressure display mode: relative display, if vacuum degree needs to be tested11.6KPaWhen using standard air pressure101.3KPa-11.6KPa=89.7KPa,The vacuum gauge is set to-89.7KPaThe displayed value is the extracted value,Other parameters are calculated and set the same;

8Vacuum pressure leakage rate:1.0KPa/Hour;

9Vacuum deviation:±0.2KpaAt its peak;

10Vacuum pump configuration:VP-1Direct connected vacuum pump.

Machine power supply:

1Voltage220V

2Current3A

3Total power0.5KW

4Circuit protection system: grounding protection, quick safety, etc.
