Hydraulic fan drive
Hydraulic fan drive should connect to tractors pre-fitted control valve. This
minimize fan speed fluctuation when lifting and putting down the machine or
other hydraulic loan.
The oil flow leads to a three-way valve for flow regulation and is regulates the hydraulic
motor speed. Fan speed have to be controlled by tractor ’ s terminal.
Fan’s technical parameters
Parameters
Capacity of hydromotor (ccm) 8
Working pressure (bar) 150
Maximum pressure on return flow (bar) 5
Oil flow (l/min) 43
Maximum fan speed (RPM) 5000
No-pressure return
No-pressure return reduces the risk of hydromotor’s damage. It is important to choose the
right position of connecting the hydromotor to hydraulic system, because:
- returning oil have to flow through the hydraulic filter,
- returning oil can’t flow through control valves, because pressure in return will be
too high.
