Excellent performance elements

Compressor

Adopt 12HP BITZER semi closed circling compressor and use R407 cooling medium, able to obtain 30kw refrigeration power at 0℃, meeting requirements at quickly generate cold ice water

 

 

 

Circling pump

Grundfos CMI series multiply levels horizontal stainless steel eccentric pump, meeting the requirements at various concentration salt water and sand dust medium, the max flow up to 10m3/h, low noise and reliable performance

 

 

 

Pressure sensor

Measure range 0~5bar, manufactured by 316 stainless steel, meeting requirements at anti medium corrode, precision better than 0.3% of full range, screw connection convenient to disassemble and binding

 

 

 

Flow sensor

Ultrasonic measure principle, support all test mediums include the deion water, non contact pincers type installation free to corrode, longer working life, repeat measurement precision up to ±1.5% of full range

 

 

Excellent performance elements

 



Lifter

Gear and rank lifter with self lock function, max hoist weight up to 200kg, suitable to test large scale samples, the lifter able to paralleling work, the hoist process stable and reliable, longer working life

 

 

 

Nozzle

The nozzles meet requirements in ISO16750-4 5.4, manufactured by 316 stainless steel materials, withstand various test medium corrode

 

 

     

Triplet shift valve

Pneumatic executor triplet ball valve, PVC valve body, better anti corrode performance, simple and reliable operation

 

 

      

Controller

Siemens SIMATIC S7-1200 controller, integrated PID_TEMP function guarantee the accurate control of water tank temperature, high efficiency running capacity guarantee real time controllable of system

 

Design at convenient operation

    

Nozzle adjustment

The nozzles fixed on the moveable platform, connected with DC motor through screw rod, move on the horizontal and vertical direction, configured crawl button on operating interface, convenient to adjust the jet spraying position on tested products.

 

    

Shift and share between jet spraying and immerge test

The equipment designed two containers like bottom water contain tray and immerge water tank, meeting different test requirements respectively: the equipment use immerge water tank when do immerge test, transparent water tank, convenient to observe the test status of samples; pick out the immerge water tank when do jet spraying test, remain enough jet spraying space, convenient to adjust and control the jet spraying position

 

 

    

Enough wiring holes, convenient to connect electrics and water circuit

Configured 4 pieces Φ100mm electric joggle and 2 pieces Φ19mm water pipe joggle, completely suit to the requirements of electric drive assembly test with load

 

 

    

Easy to wash

Big area of bottom water tray, adopt multiply rows water holes setting, convenient to wash and discharge water, shorten the shift and prepare time between dust contain test and non dust contain test


Simple and easy operation

 

Manually control function, high visual interface, visually know well about the running status and test information of equipment

 

Clearly automatic test control

*The touch screen also has the user management, parameter setting, program setting, drawing curve, alarm record and other operating interface except manual test control and automatic test control interface
