Presentation Transcript

  1. Gearbox cooling

  2. Background • Gearboxes with High Power • Duty Cycle Issue • How to stabilize temperature? • Modular cooling package for stationary applications • Pat Laake at Flo

  3. Challenges • High Viscosity Gear Lube • Cooler pressure drop • Circulation pump • Cold oil startup • Energy Management • Control Logic • How to keep simple? • Goal of small footprint • Electric motor specs • Each system different

  4. Origional Concept

  5. Cooling Circuit

  6. Electrical Logic • Enable signal from customer’s machine • Motor starters, 2HP & 3 HP • Turn system on every 5? minutes to circulate oil. If measured temperature is too high, continue running until cool. • Pressure switch: shut down if pressure drops = leak. Include time delay after startup so system can pressurize. • Lack of cooling fault: If system doesn’t cool in x period of time then activate alarm. • Power light • Service disconnect
