Embodiment Construction

[0010] When the product is working, the low-temperature fuel flows from the fuel inlet 1 into the primary fuel filter 41 of the product, and then enters the radiator core 5 after being filtered by the primary fuel filter assembly 41. When the clogging pressure of the primary fuel filter 41 exceeds the first threshold of the primary filter, the mechanical Indicator 42 sends out an alarm signal. When the clogging pressure of the primary fuel filter 41 exceeds the second threshold value of the primary filter, the inlet bypass valve 43 is opened under the influence of the oil pressure, and the fuel no longer flows through the primary fuel filter 41, and directly flows into the radiator core 5 through the inlet bypass valve 43. heat exchange. The fuel oil after heat exchange flows out from the radiator core 5, and flows out from the fuel outlet after being filtered by the fine fuel filter 91. When the clogging pressure of the fine fuel filter 91 exceeds the first threshold of the f...

Description

technical field [0001] The invention belongs to an aircraft engine lubricating oil system, in particular to an aircraft engine fuel lubricating oil integrated heat exchange device. Background technique [0002] In the past, multi-functional heat exchange devices in my country were composed of radiator cores, filter elements, valves, mechanical signal devices, temperature-sensing and pressure-sensing components and other components connected in series. A lot of space is occupied, which makes the product structure bloated, the pipeline messy, and the reliability reduced. Contents of the invention [0003] The purpose of the present invention is to design an aircraft engine fuel oil integrated heat exchange device in order to reduce the installation space, improve product reliability and safety, and require the product to meet the requirements of functional integration and structural modularization. [0004] The technical solution of the present invention: an aircraft engine ...
