Technical Field

The invention relates to the technical field of X-ray source liquid metal jet flow, in particular to a metal liquid pressurizing and conveying device based on electromagnetic force.

Background

Since 1895 German physicist W.K. Roentgen discovered X-ray, X-ray equipment has come into operation and can be applied in various directions such as imaging, diffraction scattering, spectroscopy/fluorescence characteristics, etc., which greatly promotes the development of the fields such as industry, biomedicine, measurement, academic research, etc. The simplest way to generate X-rays is to hit a metal target with accelerated electrons. Most of the X-ray related instruments on the market today generate X-rays in this way, however, the X-ray intensity of all electron bombardment type X-ray generators is limited by the heat carrying capacity of the anode material. In the conventional solid anode technology, in order to avoid the damage of the anode, the working temperature of the surface of the anode must be far lower than the melting point of the target, so that various physical properties of the target, such as the melting point, the thermal conductivity and the like, greatly limit the range of the electron beam power.

To solve this problem, the company Excillum, sweden, mastered advanced liquid metal jet (MetalJet) X-ray source technology over more than a decade of development and improvement. The liquid metal jet can bear the bombardment of a higher-power electron beam, so that the new technology can bring the X-ray flux (on the same focal spot area) which is 10 times that of the X-ray flux emitted by a common solid anode X-ray light source, and the test experience of rapidness (short test time), high brightness (high brightness) and high signal intensity (signal intensity) is realized. As such, the solid metal anode in conventional microfocus X-ray generators is being replaced by a liquid metal jet.

Diaphragm pumps, also known as control pumps, are the main type of actuator that is operated by power to vary the fluid flow by receiving a control signal from a regulating control unit. The diaphragm pump is a novel conveying machine, can convey various corrosive liquids, liquids with particles, and liquids with high viscosity, volatility, flammability and high toxicity.
