Problems solved by technology
At present, the first-line troops adopt the method of calibrating the pressure parameters of the aircraft engine hydraulic system and the main reducer hydraulic system by removing the sensors on the system and sending them to the military measurement station for calibration. The measurement station uses other systems to use the pressure calibration platform for calibration. , there is no special calibration instrument, which is time-consuming and labor-intensive, and it is easy to pollute the sensor and even the hydraulic system of the engine and final reducer, and the calibration accuracy cannot meet the requirements

Embodiment Construction
[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0015] A hydraulic pressure setting device for aircraft testing shown in this embodiment includes a casing, a circuit control module and a hydraulic pressure generating module placed in the casing.
[0016] The main function of the hydraulic pressure generation module is to provide pressure output for the equipment to be calibrated, such as figure 2 As shown, including oil cup 1, one-way valve 2, hand pump 3, lever handle 4, one-way valve 5, pressure relief valve 6, fine-tuning valve 7, pressure accumulator 8, pressure sensor 11, stop valve 13 , Pressure sensor 14. The oil cup 1 is the hydraulic oil storage element, the hand pump 3, the accumulator 8, the fine-tuning valve 7 and the pressure relief valve 6 are sequentially connected to the return pipe of the oil cup 1, and the pressure rod handle 4 is equipped as a hand pump 3 Pressurize so...

The invention discloses a hydraulic pressure giving device for aircraft testing. The hydraulic pressure giving device comprises an oil cup, a one-way valve, a hand pump, a lever type handle, a pressure relief valve, a micro-adjusting valve, a pressure accumulating pool, pressure sensors and a check valve, wherein the oil cup is used for storing hydraulic oil; the hand pump, the pressure accumulating pool, the micro-adjusting valve and the pressure relief valve are connected to a return pipe of the oil cup in sequence; the lever type handle is configured to pressurize the hand pump, so that thehydraulic oil in the oil cup is absorbed into the return pipe; the one-way valve is connected to the two ends of the hand pump, and is configured to guarantee that the hydraulic oil does not return into the oil cup through the hand pump; two paths of pressure output pipelines are arranged on the return pipe; the pressure sensors are connected with the two paths of pressure output pipelines respectively for collecting output pressure signals; and the check valve is connected to the pressure output pipelines. Through adoption of the hydraulic pressure giving device, calibration of the pressureparameters of an airplane engine hydraulic system and a main reducing hydraulic system is achieved.
Description
technical field [0001] The invention belongs to the field of aviation instruments and meters, and in particular relates to a hydraulic pressure setting device for aircraft testing used in aircraft engine hydraulic systems, final reducer hydraulic systems and the like. Background technique [0002] According to the requirements of the military equipment maintenance and support department, a special equipment is needed in the maintenance and support of aircraft to generate and output standard hydraulic pressure, and realize the control of aircraft engine hydraulic system, main reduction hydraulic system and torque etc. The calibration task can also meet the detection, regular inspection and overhaul work of the hydraulic pressure indicating system instrument and corresponding pressure sensor by the front-line troops and the overhaul factory. [0003] At present, there is no special equipment for calibrating parameters such as aircraft engine hydraulic system, main reducer hydr...
