Embodiment Construction

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

[0044] The present invention will be described from the design point of view below.

[0045] In order to ensure the convenience and feasibility of the processing of the collection plate 3 receiving the water tank, the present invention selects the scheme of placing the test tubes in a single row around the circumference; considers the convenience of water collection and measurement accuracy, chooses to divide the spray cone into equal parts; considers the versatility of the measuring device for large and small flow rates, according to Calculate the maximum flow rate given by the design and the minimum water collection time, select a suitable test tube, and design the key dimensions of the water receiving tray 4, collecting tray, and stand 1 in sequence, and install them in the following order: a. Separator 38 and collecting tray form ...

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 non-uniformity coefficient measurement test of the small-flow thrust device, is suitable for the spray non-uniformity coefficient measurement of various types of engine nozzles, and can also be used for the spray non-uniformity coefficient measurement of other equipment. Background technique [0002] In order to improve the combustion efficiency of the engine and the uniformity of temperature rise, and prevent local overheating of the engine, it is necessary to improve the atomization uniformity of each nozzle. In the prior art, the detection of atomization uniformity is usually carried out visually, which is difficult to quantify . Contents of the invention [0003] In order to solve the technical problem that the atomization effect of the existing spray is difficult to quantify, the invention provides a spray non-uniformity coefficient measuring device. [0004] Technical solution of the present invention is as foll...
