Abstract

Aircraft nose landing gear steering release valve torque test machine includes the main body of the test machine equipped with movable universal wheels and brakes, a pressure release valve torque test installation platform, a hydraulic oil circuit control system for testing, a pressure sensing test system, Main parts such as the oil leakage test pipeline of the oil inlet oil circuit, the oil leakage test pipeline for the oil return oil circuit, and the leakage oil liquid collection plate, the overall shape of the aircraft nose landing gear steering release valve moment test machine provided by the present invention The small size makes it very flexible and easy to operate, and the low cost makes it easy to test the nose gear relief valve of the aircraft. At the same time, it is easy to realize the test work of various types of pressure relief valves, thereby improving the efficiency of the aircraft pressure relief valve test operation, realizing quantitative testing, and maximizing the safety of the performance test operation of the aircraft landing gear pressure relief valve. Reduce maintenance time to increase aircraft flight time and increase revenue for airlines.

Description

technical field [0001] The invention belongs to the technical field of civil aviation special equipment testing, in particular to an aircraft nose landing gear steering release valve torque testing machine. Background technique [0002] Under the pace of the dream of a strong civil aviation country, the development of my country's civil aviation will be in a golden period. At the same time, with the sudden increase in the number of passengers, the number of aircraft is also increasing. Therefore, the rapid maintenance of civil aviation transport aircraft should be invested as soon as possible. More attention should be paid to flying missions while using it. The landing gear is an important device in the aircraft system and an important guarantee for the safe landing of the aircraft. The pressure relief valve is a key component in the traction process of the aircraft. Testing its pressure relief performance is an important means to ensure safe operation. The traditional test m...
