Abstract

The present application provides a lubricating oil nozzle with a filtering function, which includes: a nozzle housing; at least part of the nozzle arranged in the nozzle housing, one end of the nozzle is a spray hole, and the other end has a plurality of radially arranged a filter hole, the filter hole communicates with the nozzle; a spring arranged between the nozzle housing and the nozzle; and a filter screen covering the filter hole, through which the water flowing into the spray hole is made Oil is filtered. The lubricating oil nozzle provided by this application can realize simple filtering before spraying, intercept foreign matter that may block the nozzle, effectively ensure the speed and flow rate of lubricating oil spraying, and ensure the safe operation of the engine.

Description

technical field [0001] The application belongs to the technical field of nozzles, in particular to a lubricating oil nozzle with a filtering function. Background technique [0002] Lubricating oil nozzle is the most basic component in the lubricating oil system of aero-engine and gas turbine. The lubricating oil nozzle directly provides lubricating and cooling lubricating oil for each fulcrum bearing, gear tooth surface and sealing device. In order to make the lubricating oil pass through the rotating gap (such as the gap of the bearing, etc.), the lubricating oil nozzle should not only ensure that the installation is correct, so that the lubricating oil can be sprayed to the required position, but also provide sufficient injection speed. In order to take into account the injection speed and prevent nozzle hole clogging, the nozzle hole diameter is generally between 0.6mm and 1.2mm. When a large flow rate is required, multiple nozzle holes are often used to ensure the flow r...
