Problems solved by technology

At present, the domestic product pollution test is still in its infancy, and there is no special pollution test equipment and manufacturers for pump regulator products. It is urgent to design a pollution test injection system that takes into account the fixed fuel pollutant composition and fixed fuel cleanliness of pump regulator products.

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0020] See attached figure 1 , the pump regulator pollution test injection system of the present invention consists of two parts: a pollutant injection part and a pollution test part:

[0021] The pollutant injection part is used for self-cleaning and providing pollutant mixed oil, including circulation pump 1, oil discharge valve 2, dirty oil injection pump 3, dirty oil injection tank 25, electric agitator 1 26, diffuser 1 27, sampling switch 1 28. Fine filter 29, three-way valve one 30; among them, circulating pump 1, oil discharge valve 2, dirty oil injection pump 3, dirty oil injection tank 25, fine filter 29, three-way valve one 30 are connected in series in sequence, electric agitator one 26 1. Diffuser one 27 is inserted in the dirty oil tank 25, and one end of three-way valve one 30 is connected wi...

Abstract

The invention provides a pollution test injection system for a pump regulator. The pollution test injection system for the pump regulator is composed of two parts which are a pollutant injection part and a pollution test part. The pollutant injection part is used for self-cleaning and providing pollutant mixed oil liquid. The pollution test part is used for self-cleaning and examination of the pump regulator for a pollution test. By means of the pollution test injection system for the pump regulator, pollutant is mixed evenly, and the concentration of the pollutant and the pollution test time can be set autonomously as needed. Self-circulation of the system is achieved, and a pipeline can be automatically cleaned without the need for being detached.

Description

technical field [0001] The invention belongs to the technical field of reliability verification test of aero-engine fuel oil accessories, and in particular relates to a pump regulator pollution test injection system. Background technique [0002] The number of precision accessories in the hydraulic system of modern aircraft engines is increasing, and the degree of precision is getting higher and higher. bigger and bigger. [0003] With the application of full-authority digital electronic control technology in the engine fuel control system, higher requirements are put forward for the anti-pollution design of hydraulic machinery products. If the anti-pollution design of the fuel metering device is unreasonable, it will be difficult to achieve the ideal control effect even with an advanced electronic controller. The problem of anti-pollution reliability of fuel oil and control systems has become increasingly prominent. At present, the domestic product pollution test is stil...
