Abstract

The invention relates to a variety of oil pressure channel calibration devices, including an oil pressure generating unit and an oil pressure measurement and control unit; the oil pressure generating unit is used to generate pressure in the oil channel, including a pre-charging pump and a hand pump. The pump is used to decompress the oil passage and fill the oil. The hand pump is used to boost the pressure in the oil passage and the meter to be tested. By adjusting the fine-tuning valve, the pressure in the oil passage can reach the required pressure value. The check valve releases the pressure and checks the pressure. The oil pressure measurement and control unit is used to measure and control the pressure in the oil channel, including the central control module and the data acquisition module. The central control module is a single-chip microcomputer, and the pressure input and The preprocessing module receives the data transmitted by the first pressure output terminal and the second pressure output terminal and preprocesses the data, and transmits the preprocessed data to the data acquisition module, which is connected to the central control module, and the processed The data is transmitted to the central control module and displayed on the display module.

Description

technical field [0001] The invention relates to the technical field of aviation measurement, in particular to a calibration device for various oil pressure passages. Background technique [0002] A pressure gauge is an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the environment. It is widely used, and it pervades almost all industrial processes and scientific research fields. It can be seen everywhere in heat pipe network, oil and gas transmission, water supply and gas supply system, vehicle repair and maintenance factory and shop. In order to calibrate the oil pressure of the oil transfer line, a pressure gauge needs to be installed on the oil transfer line. [0003] Moreover, in the process of continuous operation and loss of the aircraft, the pressure gauge of the aircraft will be damaged to varying degrees due to various reasons, and the resulting lubricating oil, fuel and hydraulic pressure will be out of sta...
