Problems solved by technology

With the above test, the operation is complicated. Each time the hydraulic pump needs to be installed on the aircraft, and then disassembled after the test, the test efficiency is low; at the same time, more operators are needed to complete the test, and more operators are required.
In addition, during the test, the aircraft engine needs to be started, which has high noise, which has a great impact on the operating staff and also brings suffering to the operation and maintenance.

Abstract

The invention discloses an aircraft hydraulic oil pump ground-drive testing equipment which is characterized by comprising a hydraulic motor (1), an elastic coupler (2) and a drive hydraulic pump (3).The drive hydraulic pump (3) is connected with the hydraulic motor (1) through the elastic coupler (2) and is horizontally and slidably connected onto a first base (4) through a screw rod structure;the first base (4) is longitudinally and slidably connected onto a second base (5) through a screw rod structure; and a dip angle adjusting structure and a height adjusting structure arranged on the bottom part of the second base (5). The aircraft hydraulic oil pump ground-drive testing equipment has the advantages of reasonable arrangement, coordination work, high comprehensive performance, highautomation degree, high reliability, low noise, and easiness in operation and maintenance.

Description

technical field [0001] The invention relates to the technical field of testing equipment for aircraft hydraulic oil pumps, in particular to ground driving test equipment for aircraft hydraulic oil pumps. Background technique [0002] The aircraft hydraulic oil pump needs to be tested before installation and use. The actual operating conditions must be installed during the test, that is, the hydraulic oil pump needs to be installed on the aircraft engine, and then a full range of tests are carried out according to the operating conditions to test the hydraulic oil pump. Various performances and parameters to verify whether the aircraft oil pump can meet the predetermined performance requirements. The above test is complicated to operate. Each time the hydraulic pump needs to be installed on the aircraft and then disassembled after the test, the test efficiency is low; at the same time, more operators are needed to complete the test, and more operators are required. In additi...
