Problems solved by technology
[0002] During the assembly stage of the aircraft, the whole machine cannot be powered, the accessories of the hydraulic system are in a non-working state, the tightness of the connection between the conduit and the attachment, and the correctness of the installation of the attachment and the conduit cannot be checked. If oil leakage and connection errors occur, they can only be found during the debugging stage. A large amount of rework may cause machine damage and personal injury

Embodiment Construction
[0032] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.
[0033] Such as Figure 1 to Figure 4 As shown, a hydraulic system sealing and working performance inspection method in the assembly stage, including I system and II system, the specific steps are as follows:
[0034] S1: Release pressure: After the pressure is supplied, the pressure enters the hydraulic system sealing and system performance testing equipment, and the switch 1 2 and switch 2 3 are turned off. After reaching a certain pressure, the safety valve switch 1 is opened to release the pressure;
[0035] S2: Check the tightness of the system: turn on switch one 2 and switch two 3, the equipment can supply pressure to the pressure supply pipelines of system I and system II, and check the tightness of the pressure supply pipelines of system I and system II;
[0036] S3: Check the ...

The present invention relates to the field of hydraulic detection in the aircraft assembly stage, in particular to a method for inspecting the airtightness and working performance of a hydraulic system in the assembly stage, including system I and system II, and the specific steps are as follows: S1; release the pressure; S2: check the airtightness of the system; S3; Check the correctness of the brake connection of the I system; S4; Check the correctness of the brake connection of the II system; S5; Release the operation of the emergency brake handle; S6; Release the operation of the left and right main brake pedals; S7; Check the tightness of the oil receiving probe ;S8; Check the tightness of the actuator; S9; Check the non-working performance of the front cockpit brake; S10; Check the non-working performance of the front cockpit emergency brake; S11; Confirm the performance of the valve and the correctness of the connection; S12; Check the turning oil supply of the front wheel The tightness of the pipeline and the correctness of the pipeline connection; by comprehensively checking the tightness and correctness of the conduit connection, ensuring the safety of the power supply and pressure supply of the equipment, and selecting a reasonable design method, the work efficiency is improved and the inspection cost is reduced.
Description
technical field [0001] The invention relates to the field of hydraulic detection at the assembly stage of an aircraft, in particular to a method for inspecting the airtightness and working performance of a hydraulic system at the assembly stage. Background technique [0002] During the assembly stage of the aircraft, the whole machine cannot be powered, the accessories of the hydraulic system are in a non-working state, the tightness of the connection between the conduit and the attachment, and the correctness of the installation of the attachment and the conduit cannot be checked. If oil leakage and connection errors occur, they can only be found during the debugging stage. The amount of rework is large, and it may cause mechanical damage and personal injury. The present invention designs hydraulic system sealing and system performance inspection methods through the research on the logical control relationship of the hydraulic system, and manufactures inspection equipment f...
