Why Hydraulic Fan Drives?

3 main reasons

Efficiency.

70-90% Efficient. Frees up Horsepower to do work

Fuel savings. High Power to Weight Ratio.

Design advantages

Often uti lizes existing hydraulic system

Reversible - Clear clogged radiators

Installation Flexibility: Small Size, Locate anywhere

Fixed tip Clearance = 10-15% more cooling efficiency

This Fan System is still in Development Target customer is the Transit Authority, bus refurbisher, repower facility

NOT OEMs

TAs look for Fuel savings, reduction in maintenance, etc.

Now with Parker Olaer as a solution, Parker canbe able to provide a full solution

Olaer oil coolers

In the short term they can supply oil coolers to the truck markets.

Can be used for smaller radiators for hybrid trucks, smaller vehicles.

If you believe you have a potential opportunity, talk to Pat Berkner to discuss.

Sizing & Specification

Questions To Ask


32/42

Pump and Motor Sizing Questions:

Maximum fan speed needed?

Lowest pump rpm need to achieve the maximum fan speed?

Rated power of the fan at its rated speed?

Maximum power or torque available to drive the pump?

Minimum and maximum engine speed?

Maximum allowable or desired hydraulic pressure?

Other Clarifying Questions:

Thrust, axial and dynamic loads on the fan motor?

What features are needed {reversing, speed control, etc}?

Duty cycle of the fan?

Mounting, shaft and porting on the pump and motor?

Space restrictions?

Questions To Ask

32

Additional Factors:


33/42

To Accurately Calculate the Fan / Hydraulic Performance it is very important to:-

1. Account for Pump & Motor Efficiencies over the speed and temperature range.

2. Consider total hydraulic losses (hoses, valves).

3. Address Dynamic Forces on the motor:

Additional Factors:

Dynamic Load

X Axis

Dynamic Load

Z Axis

Axial Load
