Embodiment Construction

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0026] see figure 1 , The spray cone angle measurement device in the present invention includes: a spray chamber 1, a camera 2, a spotlight 3 and a nozzle holder 4. The installation position of the nozzle 5 is arranged in the spray chamber 1, and the nozzle 5 is installed in the spray chamber 1 during measurement. Wherein, an observation window 11 is provided on the side wall of the spray chamber 1, preferably, the spray chamber 1 is a cylindrical spray chamber; the observation window 11 is blocked with a transparent material, preferably, the transparent material can be transparent glass or transparent resin etc. As another example, the spray chamber 1 can be made of transparent materials. At this time, the position where the side wall of the tran...

Abstract

The invention provides a device for measuring a spray cone angle, comprising a spraying room (1), a camera (2) and a spot light (3), wherein the spraying room (1) is internally provided with a nozzle (5); the camera (2) is used for photographing the spray cone angle of the nozzle (5); and the spot light (3) is mounted on the side wall of the spraying room (1). According to the device, by reasonably arranging the position of the spot light and adjusting the brightness of the spot light, the boundary of conical spraying is clearer, so that the accuracy of the measurement is greatly improved.

Description

technical field [0001] The invention relates to the field of engine combustion chamber experiments, in particular to a nozzle spray cone angle measuring device. Background technique [0002] In the performance test of aero-engine fuel nozzles, it is necessary to measure the nozzle spray cone angle. The so-called spray cone angle is the angle between the two generatrices in the section triangle along the height of the conical spray. [0003] At present, the measurement of the spray cone angle adopts the method of mechanical scale. That is, when the fuel flow is sprayed from the nozzle at a certain cone angle, a rotating back plate that can indicate the angle is provided beside the mist cone. When the leaning plate rotates and collides with the conical surface of the conical spray, the angle indicated by the leaning plate is the angle of the spray cone. This mechanical calibration method has the following defects: it needs manual judgment with the naked eye, and the accurac...
