Accompanying drawing illustrates:
Fig. 1 is the assembly structure schematic diagram of a kind of embodiment of the utility model device.
Fig. 2 is the schematic diagram of a kind of embodiment of the utility model device.
Embodiment:
Shown in accompanying drawing 1 erection drawing, this device is made up of the standing part of the rotating part be set on water turbine macro-axis and corresponding placement with it, rotating part is closing the two halves round type machining forging on macro-axis by bolt suit, its top is to test the speed tooth 5 according to the circumference uniform distribution of power generator electrode logarithm processing, bottom is the embossing friction disk 4 processed by mould pressing technology, middle part is trigger 2 of being overrun by the symmetrical two pieces be combined and installed of bolt axis, standing part main body is mach combinaing valve body, its left side is the hydraulicdirectional control valve driving cam 1 angular displacement being converted to straight-line displacement amount depending on the top in face, bottom is the dish type angle position switch 3 that pressurized air straight line can be relied on to stretch out forward, standing part upper surface support installs by locking nut the optoelectronic switch 6 that tests the speed, the lower surface support of standing part installs acceleration oscillation gauge 7 by locking nut, the face of facing of standing part has been equipped with the electrical wiring unit 8 of standard tenminal block, the oil gas pipeline interface unit 9 of equipped standard card shell type welding junction has been drawn depending on face in the right side of standing part.Wherein electrical wiring unit 8 is for the electric signal wiring of the optoelectronic switch 6 that tests the speed, acceleration oscillation gauge 7 and dish type angle position switch 3, the input operation pressurized air external tapping that the hydraulicdirectional control valve oil circuit external tapping that three oil pipes in oil gas pipeline interface unit 9 are mechanical overspeed protection, a tracheae are dish type angle position switch 3.
According to the schematic diagram shown in accompanying drawing 2, illustrate that each function of this device is as follows.
Generating unit speed monitoring function: optoelectronic switch 6 tests the speed tooth 5 just to installation with circumference uniform distribution by testing the speed, when unit rotates, speed measurement switch 6 carries out scanning and counting by the tooth number that tests the speed turned over unit time its front inherent, can converse macro-axis rotational velocity.
Over-speed protection for machine units function: the pretensioned spring trigger head adjusted is installed in trigger 2 inside of overrunning of rotating part; when macro-axis turn up to overrun predefined value time; trigger head is protruding because centrifugal force is greater than spring tension; trigger the hydraulicdirectional control valve driving cam 1 in fixed component; two four-way oil circuits on switching valve; make oil circuit control decompression, drive the action of outside generator protection oil circuit, complete shutdown of overrunning.Trigger 2 of overrunning adopts the symmetrical mounting type in axle center, both solves eccentricity issues, and has redundancy feature again, and improve the reliability of action.
Wriggling monitoring function: after compressor emergency shutdown; outside passes into pressurized air and promotes dish type angle position switch 3 and to be tangentially pressed together on embossing friction disk 4; as unit macro-axis is wriggled; under frictional force drives, dish type angle position switch 3 can be followed and rotated and send unit wriggling alarm signal by electric interfaces unit 8 output alarm.
Swing monitoring function: by gathering main shaft runout signal with the surperficial oscillation gauge 7 be mounted opposite of macro-axis, being connected on electrical wiring unit 8 by cable, signal is outputted to upper-position unit.
