Working procedure: during experiment, high speed rotary valve observation model is received on accumulator.Consider that the impurity in hydraulic oil can form nucleon, cause the unstability that cavitation occurs, system adopts the method for height precision filter circulating filtration, and most high filtering precision is 20 μm.Model valve is imported and exported and is provided with pressure and impulser near the position of valve pocket for measuring the fluid pressure fluctuations before and after valve port as far as possible.Pulsation when high pressure hose and wave filter can flow to fluid decays, and Laboratory Furniture operative section mainly adopts high speed observation procedure to obtain the inner air pocket shape information of rotary valve.Experiment high-speed camera adopts synchronous observation method, changes high speed rotary valve spool rotating speed, and adjustment high-speed camera filming frequency, makes it identical with valve core rotation frequency or become integral multiple, to obtain steady and audible image.Meanwhile, obtained the change information of flow system flow in real time by high precision flow, realize synchronous acquisition that is flow-field visualized and flow-data.
In order to carry out front observation to the flow phenomenon of valve port inside, camera lens is parallel with valve axis and keep vertical with outer wall, and in shooting process, adjustable lens aperture and exposure time make image obtain best clearness and tonal value.Because the movement velocity of valve port fluid is exceedingly fast, and notch is small-sized, need to carry out microshot, two aspects bring very large difficulty all to shooting work, the fluid of high-speed motion is easy to produce the phenomenons such as fuzzy tail on the one hand, another aspect is because coverage is limited under macro mode, and focusing range and focusing are restricted, and is difficult to catch the flow phenomenon in whole space range.And when larger multiplying power microshot, the effective f-number of camera lens sharply reduces, and corresponding shutter speed also sharply declines, at this time just very high to the requirement of light source.Therefore, increase light intensity extremely important, need to carry out high power light filling+light source convergence technology.Under microshot pattern, pick-up lens and rotary valve notch distance are enough near, but due to spool opaque, need to adopt the mode of frontlighting (or side light filling) to throw light on, suitable space will be reserved between camera lens and valve body light is passed through.In addition, due to the valve core rotation of rotary valve, the appearance position of air pocket when occurring to observe cavitation phenomenon, is not changing under lens focusing point and screening-mode, is needing constantly to adjust light source position.
