Embodiment Construction

[0043] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0044] Hereinafter, the present invention will be described from the perspective of design.

[0045] In order to ensure the convenience and feasibility of the processing of the collecting tray 3 receiving the water tank, the present invention selects the solution of placing the test tubes in a single row on the circumference; considering the convenience of water collection and the measurement accuracy, the spray cone is selected to be equally divided; considering the versatility of the measurement device for large and small flow, according to Design the maximum flow rate and minimum water collection time to calculate, select the appropriate test tube, and design the key dimensions of the water receiving tray 4, the collecting tray, and the bench 1 in sequence, and install them in the following order: a. The separating sheet 38 and the collecting tray f...

Abstract

The invention provides a device for measuring a non-uniform coefficient of spray. The device can perform quantized measurement on a spray effect, and a nozzle with qualified atomization effect is picked out and assembled to an engine, so that the medium atomization effect of the engine is improved. The device comprises a spray collecting assembly, a water receiving assembly and a quality measuring assembly, wherein the spray collecting assembly comprises a collecting disc right facing an atomization device, a plurality of water receiving grooves are formed in the water receiving disc, and each water receiving groove corresponds to a water collecting nozzle; a water receiving disc is arranged under the collecting disc, is in threaded connection with the collecting disc and can rotate for a designated angle relative to the spray collecting disc, the designated angle and zero degree represent two positions of the water receiving disc, one is a water receiving position, and the other is a water draining position; when the water receiving disc is in the water receiving position, water receiving nozzles are aligned to the water collecting nozzles; when the water receiving disc is in the water draining position, each water collecting disc of the collecting disc is just located between two adjacent water receiving nozzles, and water flows out of water draining nozzles.

Description

Technical field [0001] The invention is applied in the uneven coefficient measurement test of a small flow thrust device, is suitable for the measurement of the spray uneven coefficient of various engine nozzles, and can also be used for the measurement of the spray uneven coefficient of other equipment. Background technique [0002] In order to improve the combustion efficiency and temperature rise uniformity of the engine, and prevent local overheating of the engine, it is necessary to improve the uniformity of atomization of each nozzle. In the prior art, the detection of uniformity of atomization is usually carried out by visual inspection, which is difficult to quantify . Summary of the invention [0003] In order to solve the technical problem that the effect of the existing spray atomization is difficult to quantify, the present invention provides a spray unevenness coefficient measuring device. [0004] The technical solution of the present invention is as follows: [0005] ...
