Abstract

The invention belongs to the technical field of a hydraulic energy system design, and particularly relates to the field of the design of an electric pump hydraulic system in an airplane. Through installing and connecting the relevant accessories of the electric pump hydraulic system on an equipment bracket of a special hydraulic system in a cabin, the method builds the electric pump hydraulic system which can work for a long time. The electric pump hydraulic system uses alternating current which is produced on the airplane, and adopts three electric pumps as energy generation devices, two electric pumps normally work at the same time, the third electric pump is started when fault occurs, so the power requirement is ensured, and the working reliability of the system is also improved; under the premise of not changing the design and installation modes of the whole original hydraulic energy system, the method can improve the power output of the whole hydraulic system through adding a set of electric pump hydraulic energy system in the cabin; and moreover, the electric pump hydraulic energy system can reliably work for a long time, so the defect that only the electric pumps can be used as emergency energy in the past is overcome.

Description

technical field [0001] The invention belongs to the technical field of hydraulic energy system design, in particular to the field of aircraft electric pump hydraulic system design. Background technique [0002] When the power of the hydraulic energy system of the aircraft is insufficient during the modification process, the method of modifying the design of the hydraulic energy system of the original aircraft is generally adopted to meet the power usage requirements, but this method requires a large number of changes to the hydraulic system of the original aircraft, and many This method of aircraft modification can effectively improve the output power of the system, but it has disadvantages such as large amount of design and modification, and long working cycle. Contents of the invention [0003] Purpose of the present invention: when a certain type of aircraft is being refitted and designed, the output power of the original hydraulic energy system is insufficient, and the...
