Device for separating and measuring air in high-pressure engine oil and method for measuring air content

Abstract

The invention provides a device for separating and measuring air in high-pressure engine oil. The device comprises a separation chamber (1), a blade (2), a gas storage chamber (3), a screw (4), a venting chamber (5), a pressure-limiting venting valve (6), a diversion partition plate (7), and a measuring chamber (8). When air is separated, the venting chamber (5) is installed on the uppermost portion of the gas storage chamber (3); when the pressure applied to venting by engine oil is larger than a spring force, the venting valve is pushed away and gas and some engine oil in the gas storage chamber (3) is exhausted through a venting hole. When air is measured, the venting chamber (5) and the pressure-limiting venting valve (6) inside the venting chamber are taken down and the measuring chamber (8) is used for replacing the venting chamber (5); and scales are marked on the upper part in the measuring chamber (8) to read the gas volume. A deflating valve (9) is installed on the uppermostpart of the measuring chamber and is used for exhausting gas in the measuring chamber (8). Therefore, air inside the high-pressure engine oil can be separated and the air content of the engine oil isreduced, so that the fault occurrence in the engine lubrication system is reduced; and the air content of the high-pressure engine oil of the engine can be measured conveniently. Moreover, the devicehas advantages of simple structure and low cost.

Description

technical field [0001] The invention relates to a device for separating and measuring engine oil, in particular to a device for separating and measuring air in high-pressure engine oil and a method for measuring air content. Background technique [0002] The development trend of modern engine technology is high explosion pressure, high power and low friction loss, which makes the working conditions of connecting rod bearing bush and main bearing bush very harsh and prone to failure. In particular, the connecting rod bearing bush and the main bearing bush are very sensitive to the air in the engine oil. If the oil entering the bearing bush contains air bubbles, it may cause air bubbles between the connecting rod bearing bush and the connecting rod bearing journal, the main bearing bush and the crankshaft bearing journal. Lubrication failure of the serious failure. [0003] Therefore, the amount of air contained in the engine oil that enters the bearing bush lubrication shoul...

AI Technical Summary

Problems solved by technology

Under the existing technology, after the engine oil enters the oil pump and is pressurized, the amount of air contained in the high-pressure oil that comes out is basically constant before entering the bearing pad for lubrication, and there is no way to reduce it.

In addition, the existing high-pressure engine oil air content measurement technology uses the German FEV oil air content measuring instrument to measure the high-pressure engine oil air content, but the air content measuring instrument is more expensive, the operation steps are more, and the equipment is heavy and inconvenient to use
