Practicable and safety design

 

Energy supply station

The equipment required compressed air, deion water, salt water all supplied by this station

Operating platform design, convenient to lab staffs working

Salt water barrel exceed 200L meeting long time test requirements

Saturation barrel isolated installation meeting the safety requirements at water-power separated

 

 

 

 

  

Saturation barrel

Withstand voltage design exceed 5bar

Constant liquid level control, electric capacity type liquid level switch test liquid level, reliable and stable

Pressure protection procedure, system automatically cut off compressed air when tested the pressure exceed 2bar

Heater anti empty heating and electric leakage protection

 

 

  

Demisting system

Formed with fresh air valve, air venting valve and fresh air fan

Air venting valve automatically opened when equipment running test, realize the air pressure in and out of test box balance

Automatically execute the fog remove procedure after test finished, finish remove fog not exceed 5 minutes

Able to manually execute that remove fog function

 

 

Simple and easy operation


① Main signal of equipment and alarm trigger indication, such as air source pressure, salt water barrel liquid level, box door signal, etc

② Test box temperature, saturation barrel temperature and atomizing pressure curve indication

③ Test box temperature, saturation barrel temperature and atomizing pressure digit indication

④ Running mode indication

⑤ Remove fog control touch key and remove fog timing indication

⑥ Test schedule indication

⑦ Equipment running information reminding

⑧ Protect type running and stop touch keys, each one operation all need be confirmed

 

 

Running mode choice, the equipment has continue atomizing and interval atomizing function

Test total time setting, the max 99999 hours

 Test box temperature setting, the max value is 50℃

Saturation barrel temperature setting, the max value is 74℃ 

Interval atomizing need set the atomizing time and rest time

Able to process communication Baud ratio and node number setting if configured series communication

Each one time parameter modification only can valid after saved

 

 

* The touch screen also has the user management, manual running, alarm record and other I/O information operating interface except running monitor and parameter setting interface

 

 

Excellent performance components

Controller

Siemens SIMATIC S7-1200 controller, integrated PID_TEMP function guarantee the accurate control temperature in test box and temperature in saturation barrel, integrated PID_Compact function realize precision control of atomizing pressure, high efficiency running capacity guarantee real time controllable of system

 

 

 

Electric-gas proportion valve

 Realize stepless control f the compressed air which enter into saturation barrel through electric-gas proportion signal; sensitivity 0.2kPa, linear: within ±1% (F.S); high speed corresponding, high stability

 

 

 

Pressure sensor

Measure range 0~4bar, suitable medium temperature up to 135℃, precision better than 0.3% of full range, realize that precision collect atomizing pressure; screw connection convenient to disassemble and binding

 

 

 

Magnetism coding sensor

Used to check the open/close status of box door, accordance with the highest safety level requirements in ISO 13849-1, SILCL 3 and IEC 62061
