Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail, as shown in Figure 1 and Figure 2:
This detects fast device of liquid-cooled machine frame assignment of traffic, comprises the pulling bayonet joint for quick connecting pipe road, also comprises short tube for connecting pipeline and for providing the electromagnetism iron ring in magnetic field; Short tube comprises Large Diameter Pipeline section and pipe with small pipe diameter section, and above-mentioned pipe with small pipe diameter section symmetry is fixed on Large Diameter Pipeline section two ends, and the free end of two pipe with small pipe diameter sections is all connected with pulling bayonet joint; Electromagnetism iron ring is close to the outside being fixed on and being parallel to liquid flow path direction short tube Large Diameter Pipeline section, and caliber and the Large Diameter Pipeline section caliber of above-mentioned electromagnetism iron ring are suitable; The pipe with small pipe diameter section of short tube and the caliber ratio of Large Diameter Pipeline section are 1:2-3; The length of electromagnetism iron ring is identical with the Large Diameter Pipeline segment length of short tube; Electromagnetism iron ring cylindrically.
This device has quick-speed plug linkage function, plug can be connected fast in the pipeline of such as Fig. 2, this device utilizes magnetic fluid under magnetic fields, produce the speciality of magnetic, as this device of Fig. 1 has magnetic area, electromagnetism iron ring, entrance pass into magnetic fluid (magnetic fluid density, viscosity are identical with the stand-by liquid coolant of frame) when additional electromagnetism iron ring is energized there is magnetic time, magnetic fluid shows magnetic, is attracted to magnetic regions.Because magnetic fluid is a kind of uniform and stable liquid that a kind of magnetic medium is dispersed in base fluid uniformly.Therefore because flow is different in every root pipeline, be adsorbed onto magnetic medium quality in device for fast detecting magnetic regions at one time different.Device for fast detecting is separated with pipeline, measures the quality Q of the magnetic medium that magnetic area is adsorbed onto
m, by the concentration P of magnetic current matter, finally calculate the fluid flow flowed in each module, reach the object of flow in test module.This device has reusable, quick release, measures fast and convenient feature.
