Drives-generators of ГП are the basic sources of feed electric power of side network of object. The drives-generators of ГП 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 ГП23 is used on the airplanes of Ту-204, Ил-96, Ан-124, Ту-22М3; ГП25 - on the airplanes of Ил- 96, Су-30, Бе-200, Ту-204; ГП26 - on the airplanes of Ту-204, Ту-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 ИПМ-10 Product Description popup.authors Петренко Павло Миколайович popup.nrat_date 2020-04-02 Close
