Problems solved by technology
There are disadvantages in the above structure: 1. When weighing, it is necessary to isolate the entire external fuel tank and cooling device from the outside world to ensure complete independence, so as to ensure the accuracy of weighing, which is cumbersome and requires operation manual operation
2. Since the weight ratio of lubricating oil loss to the entire external oil tank and cooling device is extremely small, an electronic scale with high precision is required, which greatly increases the cost of use, and the weighing precision is low and the structure is complicated

The invention discloses an aero-engine external lubricating oil tank and an external lubricating oil cooling device. The aero-engine external lubricating oil tank and the external lubricating oil cooling device are characterized by comprising an oil tank (1) arranged on an engine seat, wherein the oil tank (1) is provided with an oil outlet (1.1) and an oil inlet (1.2), the oil outlet (1.1) is located at the bottom of the oil tank (1), the oil inlet (1.2) is located in the middle of the oil tank (1), the oil inlet (1.2) communicates with an engine oil return inlet (2) through an oil pipe, theengine oil return inlet (2) is provided with an explosion-proof temperature sensor (7) and an explosion-proof pressure sensor (8), the oil tank (1) is fixed vertically and an oil level gauge (4) is arranged on the side surface of the oil tank (1), and the oil tank (1) is internally provided with an adjustment device capable of changing the cross-sectional area of the section of the oil level gauge(4). The aero-engine external lubricating oil tank and external lubricating oil cooling device is extremely convenient to operate, low in using cost, high in weighing precision, simple in structure and good in cooling effect.
Description
technical field [0001] The invention relates to the technical field of testing devices for an aero-engine oil tank and lubricating oil cooling system, in particular to an aero-engine external lubricating oil tank and an external lubricating oil cooling device. Background technique [0002] The lubricating oil system is used to provide lubricating oil to various parts of the aero-engine, reduce friction between relative moving parts, avoid wear and tear, and take away heat generated by friction and inclusions between relative moving surfaces. After the aero-engine is assembled, it is necessary to test the loss of the lubricating oil system to meet the design requirements. [0003] The hot lubricating oil at the outlet of the oil return pump of the aeroengine flows into the cooler and then into the external oil tank, and then supplies oil to the inlet of the engine lubricating oil booster pump. During the test, the loss of lubricating oil is calculated within the set time ran...
