Project Description

Oil Laboratory needed for Automatic Transmission Fluid (ATF) testing: oil side thermal cycle test per the below on 3 or up to 6 units (1/2" NPT connections) . An additional TOC flow loop will need to be present to allow for the TBV wax valve actuation throughout the testing and with differential pressure transducer(max 30 psi) to monitor.
Test set up flow schematic will be provided.

Part #1
0) Oil type (ATF): ATF+4
1) Mounting: No mounting will be required, but additional flow loop will need to be installed into the TOC flow ports
2) Physical set up : See flow schematic,
3) Min temperature (°C); 23.9 C
4) Max temperature (°C): 135.5 C
5) Cycle Time-Total (s): 20 cycles / hour (180 seconds per cycle)
6) Cycle Time Portion Hot/Cold/(s): 90s/90s
7) Initial ramp rate (°C/s): Not Specified, generally linearly rising
8) Min hold time 60 (sec) after outlet >130.5 (°C) and cold <28.9C for 60s
9) Inlet pressure Max or Range (kPa gage); Not controlled
10) Flow Range (lpm): 9.5 LPM (keep min flow >7.6 lpm)
11) Required # of cycles: 1,500 cycles

Part #2: Oil type (ATF): ATF+4
1) Mounting: No mounting will be required, but additional flow loop will need to be installed into the TOC flow ports
2) Physical set up : See flow schematic
3) Min temperature (°C); 23.9 C
4) Max temperature (°C): 79.4 C
5) Cycle Time-Total (s): 30 cycles / hour (120 seconds per cycle)
6) Cycle Time Portion Hot/Cold/(s): 60 sec/60 sec
7) Initial ramp rate (°C/s): Not specified, generally linearly rising.
8) Min hold time 40 (sec) after outlet >75 (°C)
9) Inlet pressure Max or Range (kPa gage); Not controlled
10) Flow Range (lpm): 9.5 LPM +/- 1.9 lpm: (keep min flow >7.6 lpm)
11) Required # of cycles: 3,500 cycles
