An engine lubricating oil heating device

Abstract

The invention discloses a lubricating oil heating device for an engine, which relates to the technical field of aviation equipment, and comprises a box body. The lubricating oil tank and the water tank are arranged in the box. The water tank is surrounded by the outer surface of the lubricating oil tank. A closed space that is not connected to each other is formed; the lubricating oil tank is provided with lubricating oil drawn from the engine, and the water tank is filled with cold water; it also includes a water heater, a heat exchanger, a water circulation system and a lubricating oil circulation system. After being heated by the water heater, the water in the water tank exchanges heat with the water in the water circulation system in the heat exchanger through the water circulation system. In the present invention, the thermal resistance heater is energized to heat water as a heat source, and the hot water is delivered to the heat exchanger through the water pump and the water circulation system pipeline, and the lubricating oil extracted from the engine oil storage tank is heated through the heat exchanger, and the PLC control system collects in real time The temperature data of the water outlet of the heater adjusts the heating power of the heater to achieve precise heating of the lubricating oil.

Description

technical field [0001] The invention relates to the technical field of aviation equipment, in particular to engine lubricating oil heating equipment. Background technique [0002] In order to ensure the safety and service life of the aero-engine, all parts of the engine need to be lubricated. The aero-engine is a power machine that requires very high lubrication performance of lubricating oil. Although the lubricating oil used in aero-engines is usually the lubricating oil with the best performance, it also has the characteristic that the lubricating performance decreases as the ambient temperature decreases, and there are certain requirements for the operating environment temperature. When the outside temperature is lower than -20°C, The lubricating performance of the lubricating oil will be greatly reduced, and the lubricating performance will be lost, causing the aeroengine to often fail to start normally, so that the aircraft cannot take off normally.
