HYDRAULIC DRIVE FAN CIRCUIT
(Refer to the COMPONET OPERATION / Others
group.)
(Refer to the COMPONET OPERATION / Hydraulic
Fan Motor group.)
•
Pressure oil from the fan pump flows to the fan
motor through the flow control valve and the
reverse rotation spool.
•
Current corresponding to the hydraulic oil
temperature is sent from MC to the flow control
solenoid valve.
•
Pressure oil is supplied to the flow control valve
end in response to the stroke when the flow
adjusting solenoid valve is excited.
•
When the flow rate control valve is operated,
pressure oil from the fan pump to the fan motor is
restricted, and speed of the fan motor is
controlled.
•
When the fan reverse rotation switch is turned ON,
current flows from MC to the reverse rotation
control solenoid valve.
•
When the reverse rotation control solenoid valve
is operated, pressure oil is supplied to the reverse
rotation spool end.
•
When the reverse rotation spool is shifted, the
inlet port of pressure oil supplied to the fan motor
is shifted, and the fan motor rotates reversely.
