Abstract

The application discloses a cavitation erosion detecting device for a cylinder liner. The cavitation erosion detecting device for a cylinder liner includes: a static pressure sensor for measuring theoverall pressure data of cooling water on a maximum thrust side, wherein the maximum thrust side is a position where the sidewall thrust of the cylinder liner is maximum when a piston moves on the cylinder liner; a dynamic pressure sensor for measuring the pressure fluctuation data of the cooling water on the maximum thrust side; and a processor for filtering the overall pressure data and the pressure fluctuation data, and detecting the cavitation erosion condition according to a processing result. The method can perform accurate cavitation erosion detection under a real engine operating condition. The present application also discloses a cavitation erosion detecting method for a cylinder liner and a computer readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a cylinder liner cavitation detection device, method and a computer-readable storage medium. Background technique [0002] Under the excitation of the piston, the cylinder liner of the engine will vibrate, and the cooling water in the engine will generate dynamic pressure. At the same time, the cooling water on the surface of the cylinder liner will produce steam due to its high temperature, resulting in air bubbles and steam pressure. When the overall static pressure of the cooling water is less than the steam pressure due to dynamic pressure fluctuations, the bubbles will expand and burst. The huge bursting of the air bubbles will cause impact on the surface of the cylinder liner, causing the material on the surface of the cylinder liner to peel off, causing the cylinder liner to fail, and finally the engine to fail. Therefore, after the engine design is completed, the cavita...
