OW 4002

OW 4002The OW 4002 is a water re-cooled oil circulation pump designed to facilitate anode heat dissipation of x-ray tubes. The heat energy produced by the x-ray tube is transferred via an oil/water heat exchanger. The cooling aggregate is designed for re-cooling of tube-cooling oil for bipolar x-ray tubes. The water-cooled oil circulation pump system can cool x-ray tubes with 4200 W anode heat dissipation under conditions of constant operation if sufficient flow of cooling water at a low enough temperature is available. A thermostat valve controls the oil temperature and minimizes water consumption. If, for economical or technical reasons, a re-cooling of the tube-cooling oil from the water supply is not feasible, we recommend an air-re-cooled oil circulation pump. The OW 4002 is equipped with a fail-safe turbine flow rate monitor.

Function:
The hot tube-cooling oil returns via the oil flow switch through the oil/water 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 connector. The cooling water is supplied to and returned from the x-ray tube through two hose connectors.

Electrical Control:
The OW 4002 cooling pump is connected by a 5-wire connecting cable supplying the circulation pump from the x-ray control unit and connects 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 (17 l/min) is not ensured. A thermostat switch opens the circuit in case the cooling water temperature exceeds the set temperature (50C). Both switches reconnect automatically after safe cooling is ensured.

Water Supply:
The heat dissipated from the X-Ray tube and also the dissipation heat from the drive of the pump has to be transferred by the oil/water heat exchanger to the cooling water. The water flow is controlled by a thermostat to maintain a constant oil temperature of 40C. This, however, can only be accomplished if sufficient water flow rate and water temperature (see diagram) are provided.

OL 4503

OL 4503The OL 4503 is an air re-cooled oil circulation pump designed to facilitate anode heat dissipation of bipolar x-ray tubes when for economical or technical reasons a re-cooling of the tube-cooling oil from the water supply is not feasible. The air-cooled oil circulation pump system is suitable for normal temperature climate and can cool x-ray tubes with 4500 W anode heat dissipation up to an ambient temperature of approx. 32C. The design allows the cooling pump to transfer the heat from the x-ray tubes to the ambient air. Therefore, sufficient fresh, cool air supply must be guaranteed. The OL 4503 is equipped with a fail-safe turbine flow rate monitor.

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 supplying the circulation pump from the x-ray control unit with 230 V 50/60 Hz and connects 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 (55C). 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-contained 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.

OLK 50

OLK 50The OLK 50 is an air-cooled refrigeration aggregate designed to facilitate anode heat dissipation of the x-ray tube when operating at high ambient temperatures (up to 40 C) and can also be used when, for economical reasons a re-cooling of the tube-cooling oil from the water supply is not feasible. The design allows the cooling aggregate to transfer the heat from the x-ray tubes to the ambient air. Therefore, sufficient fresh air supply must be guaranteed. For operation at up to approximately 20C we recommend the oil cooling pump OL 4503. If re-cooling from the water supply is available, the oil cooling pump OW 4002 is recommended. The aggregate is mounted in a square tube frame and is mobile on 4 casters. The OLK 50 is equipped with CFC-free coolant.

Function:
The cooling aggregate is designed for re-cooling of tube-cooling oil for bipolar x-ray tubes. The air-cooled aggregate is suitable for tropical climate and can be operated at an ambient temperature of up to 40 C. A circulation pump for the cooling oil, a reservoir (approximately 25 l) and safety devices for maximum oil temperature (55 C) and minimum circulation flow rate (17l/min) are completely wired, installed in the aggregate and connected. The aggregate is mounted in a square tube frame and is mobile on 4 casters. The hot tube cooling oil returns via the oil flow switch and through the 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 thermometer probe.

Cooling Circuit:

  • The cooling circuit consists of
  • Full-hermetic compressor
  • Air cooled condenser
  • Cooling agent dryer
  • Cooling agent viewing glass with hygroscope
  • Expansion valve
  • Evaporator/heat exchanger
  • High and low pressure regulator
  • Corresponding quick-lock connectors

All mobile components of the compressor, including the drive motor, are hermetically sealed in a housing. The surface of the air-cooled condenser has generous dimensions to ensure reliable operation even at high evaporation and ambient temperatures. The ambient air is taken in through the condenser by means of the ventilator and is expelled via the compressor through the protective grill. Inverse rotation of the ventilator would reduce the air flow rate drastically, thus reducing the cooling capacity of the aggregate. The cooling agent liquefied in the condenser gets to the expansion valve after passing through the oil reservoir, the dryer and the viewing glass. Here the pressure is released from the condenser to the evaporator pressure. In the heat exchanger the heat required for this expansion is taken from the hot cooling oil. The expansion valve controls the flow of cooling agent required to cool to a certain temperature sensed at the heat exchanger’s output side.

Electrical Control:
The standard version of the cooling aggregate is sized for connection to a 400 V 50 Hz / 440 V 60 Hz three-phase power supply and is connected to the power via a 5-wire power cable. The live leads are labeled R/S/T to be connected to the phases, the blue conductor to the neutral (Mp) and the green/yellow to ground. A second 5-wire connecting cable supplies the circulation pump from the x-ray control unit and connects the safety circuits to the control to ensure safe operation of the

Safety Circuit:
The safety circuit monitors the cooling oil supply to the x-ray tube. The circuit includes an oil flow switch, which opens the circuit in case a minimum flow rate of the cooling oil (17 l/min) is not ensured. A thermostat switch opens the circuit in case the cooling water temperature exceeds the set temperature (55C). Both switches reconnect automatically after safe cooling is ensured.

Air Supply:
The heat absorbed by the heat exchanger and also the dissipation heat from the drive of the compressor has to be discharged by the air cooled condenser. If the unit is operated in a small, self-contained room the room temperature will built up rapidly. As shown in the overleaf diagram the cooling capacity decreases with increasing ambient temperature. It is therefore important that sufficient air circulation is provided for the OLK.

Maintenance:
All components of the cooling aggregate are selected to be maintenance-free. However, it is crucial that the condenser be kept clean. Also, the cooling oil level in the oil reservoir should be observed and topped up if required.
