Abstract

The invention relates to a device for detecting the function of an oil fuel booster pump of a civil aircraft. The device comprises a main fuel tank, an auxiliary fuel tank, a fuel oil liquid indicator, a fuel oil liquid regulating valve, a flow (pressure) regulating valve, a turbine flowmeter, a precision pressure gauge, an electric motor pump assembly, an oil suction filter, an oil return filter, a blocking alarm, a flow quantity display meter, a shutoff valve, a medium frequency amperemeter, an operation table, a cooler and a thermometer. In the device, the alternative test oil of which the oil flash value is much higher than that of aviation fuel oil RP-3 is adopted, so that the risk of combustion explosion under the factory condition is reduced; the main fuel tank and the auxiliary fuel tank do not turn over, and the oil leakage is avoided; rapid and accurate regulation on the height of liquid level is ensured by an oil well pump and the liquid regulating valve; more quick and stable regulation on the flow of the outlet of a tested pump is realized by an electric control precision throttling valve; and the temperature of a fuel oil tank is stabilized within the ranges of setting temperature + / -2 DEG C because the opening of a proportion water valve is matched with the temperature of the fuel tanks. The whole equipment system has a compact structure, safe and practical performance and attractive appearance, and is efficiency and convenience in operation.

Description

technical field

[0001] The invention relates to a detection device, in particular to a detection device for the test function of a civil aircraft fuel booster pump. Background technique

[0002] The test equipment used to test the various functions of the civil aviation aircraft fuel booster pump is to determine whether the performance of the pump is qualified and whether it meets the airworthiness safety standard by simulating whether the various performance parameters of the pump meet the specified range for installation and use.

[0003] In foreign countries, with the development of civil aviation aircraft flight and system technology, fuel booster pumps have been used for decades. In the United States and Europe, fuel booster pump detection technology and equipment have been widely used.

[0004] In order to meet the airworthiness and safety requirements of military and civilian aircraft fuel booster pump products, our country also has testing equipment that completes s...
