Hydraulic axial load device for airplane air circulator rotating components

Abstract

The invention discloses a hydraulic axial load device for airplane air circulator rotating components. The hydraulic axial load device comprises a hydraulic supply unit, an axial load action unit and a public pull-rod elongation detecting unit, wherein the axial load action unit is connected with a public pull rod of an air circulator rotating component to be detected, the hydraulic supply unit is communicated with the axial load action unit and supplies hydraulic power for the same, the axial load action unit moves to elongate the public pull rod under the hydraulic action, the public pull rod elongation detecting unit is provided with a dial indicator installed above the axial load action unit and contacts with the same, the axial load action unit pushes the dial indicator during moving, and elongation of the pull rod after elongation can be obtained by reads of the dial indicator. The hydraulic axial load device can apply axial load on the airplane circulator rotating components and can reliably acquire accurate elongation of the public pull rod.

Description

technical field [0001] The invention relates to a disassembly and assembly device for aircraft parts, in particular to a hydraulic axial load device for a rotating assembly of an aircraft air cycle machine. Background technique [0002] There are two main types of air-conditioning cycle refrigeration systems for modern civil aviation aircraft: low-pressure water-removing refrigeration systems and high-pressure water-removing refrigeration systems. Mainstream civil aviation aircraft use high-pressure water-removing air cycle refrigeration systems, which include compressed air supply sources, primary heat Accessories such as exchangers, second stage heat exchangers, condensers, reheaters, water separators, air cyclers, etc. After the air supply passes through the primary heat exchanger, the compressor and the second stage heat exchanger, it first passes through the hot side of the reheater, the condenser, the water separator and the cold side of the reheater, and then flows in...

Problems solved by technology

If one uses a common wrench or socket tool, it is simply not capable of tightening the locking nut; the two used long-distance calipers to measure the length of the common pull rod before and after the extension, which is easy to be affected by people, things, things, etc. The reason is that multiple reworks are required; the hose used by the three in the past was a single hose. When replacing and repairing other types of air cyclers, the hose must be removed from the axial load unit every time and installed on other The axial load unit is very time-consuming and labor-intensive, so it is necessary to develop an integrated special equipment to achieve safe and quick disassembly, accurate and reliable work, and improve efficiency.
