A device for detecting the filtering effect of an engine filter element and its application method

Abstract

The invention provides a device for detecting the filtering effect of an engine filter element and a using method thereof, and relates to the field of assembly detection of aero-engines. The device comprises a shell, a signal transmitting member, and a connector. The using method comprises: immersing the device for detecting the filtering effect of the engine filter element and the connector of the detected filter element in specified oil; detecting the detection start time and the filling end time of the oil flowing into the detected filter element; and comparing the time detection result with the specified required time of the detected filter element. According to the device for detecting the filtering effect of an engine filter element and the using method thereof, the working state ofthe engine filter element can be effectively simulated, the start point-end point can be accurately timed and the liquid level position when the filter element is just filled by using the principle ofsimultaneous liquid inlet simultaneous timing, the detection efficiency is improved, and the protection for the normal operation of the engine is provided.

Description

technical field [0001] The invention relates to the field of assembly detection of aero-engines, in particular to a device for detecting the filtering effect of an engine filter element and a use method thereof. Background technique [0002] The structure of the aero-engine filter element consists of an upper orifice portion 13 (such as figure 1 ) and the middle cylindrical filter body part 14 (such as figure 1 ) and the lower end plug 15 (such as figure 1 ) combined to form a rotary cavity, its function is to filter the impurities in the oil when the engine is working, so as to ensure the continuous and effective operation of the engine. Inevitably, it is necessary to check whether the filtering effect meets the requirements in the assembly or maintenance of the engine. If the filter element is installed on the engine without testing, it will very likely cause insufficient oil supply to the engine, and even cause tragic consequences of machine crash. Therefore, how to s...

AI Technical Summary

Problems solved by technology

There are two main problems in this kind of direct visual judgment: 1. The start time is not accurate, and it cannot follow the principle of simultaneous liquid filling and timing, and it does not detect under the simulated working state with oil pressure on the periphery; 2. Due to the liquid level is full position in the element specified T-section (eg figure 1 ), not at the element U orifice (eg figure 1 ), visually judge the time when the liquid level is not full

Therefore, according to the original method, it cannot be accurate and effective and meet the requirements of the simulated working state.
