Function
The hot tube cooling oil returns via the
oil flow switch and through the air-cooled
radiator/heat exchanger and, after
cooling down, into the oil reservoir. The
oil reservoir is vented to the atmospheric
pressure. The circulation pump drains
the oil from the reservoir and feeds it to
the oil outlet quick-lock connector, via the
thermostat probe.
Electrical control
The OL 4503 cooling pump is connected
by a 5-wire connecting cable supply-
ing the circulation pump from the X-ray
control unit with 230 V 50/60 Hz and con-
nects the safety circuits to the control to
ensure safe operation of the X-ray tube.
Safety circuit
The safety circuit monitors the cooling
oil supply to the X-ray tube. The circuit
includes a fail-safe oil turbine flow rate
monitor, which opens the circuit in case
a minimum flow rate of the cooling oil
(22 l/min) is not ensured.
A thermostat switch opens the circuit in
case the cooling oil temperature exceeds
the set temperature (55°C). Both switches
reconnect automatically after safe cooling
is ensured.
Air supply
The heat dissipated from the X-ray tube
and also the dissipation heat from the
drive of the pump and ventilator has to be
discharged by the air cooled radiators. If
the unit is operated in a small, self-con-
tained room the room temperature will
built up rapidly. As shown in the below
diagram the cooling capacity decreases
with increasing ambient temperature. It is
therefore important that sufficient cool air
supply is provided for the OL 4503.
