Description

The aim is the development of signaling devise pressure for the units of the energy supply system of airplanes (drives-generators GP23, GP25-2 and GP26): - signaling devise СРМ for the drive-generator GP23; СРМ6 - for the drive-generator GP25-2; СРМ9 - for the drives-generators GP25 and GP26. Drives-generators of GP are the basic sources of feed electric power of side network of object. The drives-generators of GP are the main sources of feed electric power of the onboard network of object and consist of alternating current generator with hydromechanical drive constant turns/ Hydromechanical drive constant turns provides on the billow of generator permanent 12000 turns in a minute. The drive-generator of GP23 is used on the airplanes of Tu-204, Il-96, An-124, Tu-22М3; GP25 - on the airplanes of Il- 96, Su-30, Be-200, Tu-204; GP26 - on the airplanes of Tu-204, Tu-214. The purpose of the CPM signaling device is the closure of the electrical circuit when the differential pressure in the hydraulic system decreases to a predetermined value and the electrical circuit disconnection when the differential pressure in the hydraulic system increases to a predetermined value. CPM signaling device should include: - closing-disconnection circuit knot; - microswitch; - electro-connector. The CPM6 and СРМ9 signaling device must contain: - closing-disconnection circuit knot; - microswitch. Principle of operation of the signaling device is based on the ability of the spring-loaded piston to move under the action of a varying pressure drop acting on opposite sides of the piston. A piston, operation on the microswitch rod, opens or closes respective contacts of microswitch. The feed of signaling device comes true from network of direct-current by tension 27 volt. An environment for CPM is atmospheric air, for CPM6 and CPM9 - working fluid IPM-10
