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 invention relates to the field of aircraft assembly stage hydraulic detection, and concretely relates to a method for checking sealing performance and working performance of an assembly-stage hydraulic system. The system comprises a system I and a system II. The method comprises the following specific steps: S1; releasing the pressure; s2; checking the sealing performance of the system; S3; checking the correctness of brake connection of the system I; S4; checking the correctness of brake connection of the system II; S5; releasing the operation of an emergency brake handle; S6; relieving left and right main brake pedal control; S7; checking the sealing performance of a refueling probe; S8; checking the sealing performance of an actuator cylinder; S9; checking the brake non-working performance of a front cabin; S10; checking the non-working performance of the emergency brake of the front cabin; S11; determining valve performance and connection correctness; and S12; checking the sealing performance of a front wheel turning fuel supply pipeline and the correctness of pipeline connection. The sealing performance and correctness of conduit connection are comprehensively checked, thesafety of power supply and pressure supply of equipment is ensured, and reasonable design method is selected, so the working efficiency is improved, and the checking 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...
