Metal ceramic X ray tube filled with water cooling anode device

Abstract

The invention discloses a metal ceramic X ray tube filled with a water cooling anode device. the water cooling anode device is arranged in the metal ceramic X ray tube and is hermetically connected on a base of a metal ceramic tube casing, the top of the metal ceramic tube casing is provided with a connecting ring, and a cathode focusing device is connected with the connecting ring in an argon arc welding way; a locating ring is hermetically connected with the metal ceramic tube casing and a tail cover is connected with the locating ring, and an anode cover is hermetically connected with the water cooling anode device. By adopting the metal ceramic X ray tube filled with the water cooling anode device to replace an air cooling anode structure design in an existing metal ceramic C ray tube, the anode dissipation power can be doubled, the cooling effect can be improved, the limit of a traditional 1:1 operation can be overcome, a way of continuously operating in a portable industrial X ray device can be realized, and the metal ceramic X ray tubes at different focusing points and different power can be formed by the conversion and adjustment on the cathode focusing device.

Description

technical field [0001] The invention relates to an X-ray tube, in particular to a cermet X-ray tube equipped with a water-cooled anode device used in a gas-insulated industrial X-ray machine. Background technique [0002] There are two common ways to produce rays, one is that high-speed electrons hit metals, and the other is that radioactive isotopes are emitted from the nucleus. The former emits X-rays, and this known method is used in X-ray devices to generate X-rays. Usually the work of the portable X-ray machine is intermittent, that is, the ratio of work to rest is 1:1, which mainly depends on the flaw detection at the work site, and the pursuit of small size, light weight, and easy portability. X-ray tubes using metal-ceramic structure adopt SF6 gas insulation and air-cooled anode structure without exception. The anode is grounded, and the 1:1 mode of power on and rest is indeed a technological progress. In the 21st century, the trend of automated production is becomi...

Problems solved by technology

X-ray tubes using metal-ceramic structure adopt SF6 gas insulation and air-cooled anode structure without exception. The anode is grounded, and the 1:1 mode of power on and rest is indeed a technological progress. In the 21st century, the trend of automated production is becoming more and more The more powerful, the original 1:1 working mode is still in demand in the market, but because the heat conduction method of the air-cooled anode structure is to assemble a cooling radiator on the periphery of the anode body, and then cool it naturally by the cooling medium or by blowing air from the fan , to achieve the balance of heat generation and cooling curves, that is, work: rest = 1:1, beyond this work mode will bring negative effects, the X-ray tube will be damaged due to overheating, and the heat dissipation of the air-cooled anode structure is not sufficient. For continuous work clearly cannot meet the needs of
