Working principle:
first, the new cooling insulating oil is replaced with the X-ray bulb tube 13, and when the cooling insulating oil is replaced, as shown in fig. 2, a new oil tank 16 and a waste oil tank 18 are prepared, and 25L of qualified cooling insulating oil subjected to vacuum drying treatment is added to the new oil tank 16. Disconnecting the quick joint on the cathode side of the bulb tube 13, putting one end of a new oil pipe 17 which is emptied and filled with oil into a new oil barrel 16, and connecting the other end of the new oil pipe 17 with the cathode side joint of the bulb tube 13; the radiator 15 end of the X-ray tube is connected with a waste oil pipe 19, and the waste oil pipe 19 is inserted into a waste oil barrel 18.
The circulating pump 14 is started (the arrangement and connection relation of the bulb tube 13, the radiator 15 and the circulating pump 14 belong to accessory parts of the X-ray bulb tube), waste oil in the X-ray bulb tube system is discharged from the waste oil pipe 19 and enters the waste oil tank 18, meanwhile, fresh oil is automatically sucked into the bulb tube 13 through the fresh oil pipe 17, the color of the waste oil continuously becomes close to that of the fresh oil along with the continuous discharge of the waste oil, when the color of the oil discharged from the waste oil pipe 19 is completely consistent with that of the fresh oil, the oil change is finished, and the waste oil pipe 19 and the fresh oil pipe 17 are removed.
After the online oil change is finished, a small amount of air bubbles exist in the bulb tube cooling insulating oil circulation system after the oil change, so that the normal operation of the system is seriously influenced, and the vacuum pumping and the air exhausting are required.
When the vacuum system is vacuumized and exhausted, as shown in fig. 3, the vacuum system is connected according to the illustration, wherein the oil inlet end 6 of the second connecting pipe 5 is connected with the radiator 15, the oil outlet end 7 of the second connecting pipe 5 is connected with the cathode side of the bulb 13, two vacuum valves 8 are opened, the vacuum pump 1 is started to operate for 20 minutes, firstly, large bubbles in the system are pumped out in advance, the circulating pump 14 is started in a state that the vacuum pump 1 is started, the vacuum tank 2 is vacuumized by the vacuum pump 1, at the moment, negative pressure is generated in the vacuum tank 2, and tiny bubbles adhered in a system pipeline are circularly discharged to the vacuum tank 2 along with oil and are pumped out through the vacuum pump 1 to operate for 3-5 hours.
Since bubbles in the system are collected under the oil circulation vacuum and enter the circulation pump 14, the circulation pump 14 idles and heats, the circulation stops, and the exhaust efficiency is influenced.
In order to prevent the cooling insulating oil from exceeding the safe liquid level of the vacuum tank 2 and entering the vacuum pump 1 due to bubble expansion, when the liquid level exceeds the safe liquid level, namely, the liquid level exceeds the correlation position of the emitter 11 and the receiver 12, the oil shields the emitted light, at the moment, after the processor receives the electric signal of the receiver 12, the processor controls the electromagnetic valve 10 to open for 5 seconds, the liquid level is closed after recovery, the reciprocating circulation is continued until no bubble is emitted from the liquid level in the vacuum tank 2, the liquid level does not change greatly along with vacuum and exhaust, and the bulb 13 vacuumizes to finish.
Therefore, the utility model can discharge the system and the gas in the cooling insulating oil in a vacuumizing mode after the cooling insulating oil is replaced on line for the X-ray bulb tube, recover the cooling insulating performance of the system and ensure the normal operation of the system.
Therefore, in the use process of the CT, when the bulb tube 13 has slight faults such as insufficient heat dissipation, ignition and the like, the deteriorated insulating oil in the system (the bulb tube assembly and the radiator) can be discharged under the state that the bulb tube 13 is not disassembled, meanwhile, new cooling insulating oil is input, then the new cooling insulating oil is circulated in vacuum by an external vacuumizing device, and the system and the gas in the cooling insulating oil are discharged, so that the cooling insulating performance of the system is recovered.
The risk of damage to the maintenance and disassembly bulb 13 during transport is avoided in this way; avoiding the risk of filament blow damage during the re-installation calibration of bulb 13; after the whole oil change, the faults of insufficient heat dissipation, ignition and the like of the bulb tube 13 are solved, the service life of the bulb tube 13 is effectively prolonged, the equipment downtime can be reduced for a user, and huge accessory purchasing cost is saved.
