Abstract
The utility model relates to an exhaust throttling device for an axial compressor performance test, which is a structural improvement on a conventional exhaust throttling device of a compressor testing machine. The exhaust throttling device is a set of exhaust throttling doors which are composed of a moving disc (2) and a fixed disc (1). Each of the fixed disc (1) and the moving disc (2) is provided with eight circumferentially uniformly distributed blocking sheets, wherein air circulation space is arranged between every two blocking sheets. The exhaust throttling doors are disposed inside an exhaust casing of a compressor testing equipment, and are tightly connected with a rear end of a test member. According to the design, the air circulation space of the fixed disc (1) is slightly smaller to the area of the corresponding blocking sheets of the moving disc (2). During the test, an aim of adjusting the exhaust flow can be fulfilled by adjusting the exhaust area through controlling the moving disc (2). After the completion of the improvement, the exhaust throttling can substantially reduces the influence on compressor performance parameter admission by the exhaust chamber effect, and thus helps to improve the test work efficiency.
Description
Technical field
The utility model belongs to aero-engine compressor test field, relates in particular to the exhaust regulative mode optimal design of compressormeter.
Background technology
Flourish along with domestic air mail industry in recent years, the aeromotor development work of advanced model has also entered the through engineering approaches stage, pneumatic plant is as one of critical component of aeromotor, and design is complicated, development difficulty is large, therefore verification experimental verification work seems particularly important to its design optimization and complete machine through engineering approaches application in tandem.
At present, the exhaust throttle of most of compressormeters is to adopt at exhaust system tip designs control valve or at exhaust collector place, the modes such as venetian blind type adjusting vane to be set and to regulate extraction flow; In process of the test, these two kinds of frame modes can cause exhaust system " cavity volume effect ", and the sensitivity of system is lower, and Installation and Debugging are loaded down with trivial details, affect the accurate admission of test figure and the lifting of experiment work efficiency.
Utility model content
The purpose of this utility model: adopt new exhaust restriction means, object is to reduce the impact of exhaust in process of the test " cavity volume effect " on Capability of Compressor, the work efficiency of raising process of the test.
The technical solution of the utility model: in order to solve the problems of the technologies described above, detailed technology scheme of the present utility model is as follows: described device is a set of exhaust throttle being made up of Moving plate 2 and quiet dish 1, quiet dish 1 and Moving plate 2 all have 8 circumferential uniform jams, and between every jam, leave circulation of air space, described exhaust throttle is installed on the exit casing inside of Compressor test equipment, and is next to testpieces rear end.
Described exhaust throttle is embedded in exit casing leading portion and is bolted connection, and simultaneously in order to guarantee that Moving plate 2 can rotate in a circumferential direction flexibly, need install bearing 4 additional in Moving plate 2 both sides, and strict control gap when mounted; By drive unit syndeton 3, Moving plate 2 is regulated.When exhaust throttle work, change the ventilation area of quiet dish 1 by rotation Moving plate 2, to change testpieces leaving area and its exhaust back pressure is regulated.
The beneficial effects of the utility model: the design has reduced the impact of exhaust in process of the test " cavity volume effect " on Capability of Compressor, the work efficiency of raising process of the test; The exhaust chamber that reduces exerciser can better be simulated the real work state of compressor part, and admission compressor instability border more accurately, for the test in tandem of engine complete machine provides strong support; Meanwhile, the reducing of exhaust chamber can be improved the ripple frequency of pneumatic plant in the time of astable workspace, reduces air pulsing energy, improves experimental safe coefficient.Installation and Debugging are convenient and swift can better shorten the test preparatory period, improves the effective rate of utilization of testing equipment; Thereby improve the degree of regulation of trystate and regulate efficiency to shorten test period, especially reducing Compressor test part and enter the time of high rotating speed and unsteady-stage conditions, greatly reducing the operation risk of test, improving test efficiency, saving experimentation cost.
Accompanying drawing explanation
Fig. 1 disc type exhaust throttle principle schematic;
Fig. 2 disc type exhaust throttle installation site schematic diagram;
Fig. 3 disc type exhaust throttle mounting structure schematic diagram;
Wherein, 1 is that quiet dish 1,2 is that Moving plate 2,3 is drive unit bindiny mechanism, and 4 is bearing.
Embodiment
Below by embodiment, the utility model is described in further detail:
Referring to Fig. 1, a kind of exhaust restriction means for axial flow compressor performance test is by a set of disc type exhaust throttle being made up of Moving plate 2 and quiet dish 1, quiet dish 1 and Moving plate 2 all have 8 jams circumferentially uniform, and between every jam, leave circulation of air space, in figure, dash area is jam region, white space between jam is circulation of air space, and quiet dish 1 and Moving plate 2 are symmetrical structure back-to-back.When the work of disc type exhaust throttle, change quiet dish 1 ventilation area by rotation Moving plate 2 and change testpieces leaving area and its exhaust back pressure is regulated to arrive.
Referring to Fig. 2 and Fig. 3, the utility model is installed on the exit casing inside of Compressor test equipment, and is next to testpieces rear end.Exhaust throttle is embedded in exit casing leading portion and is bolted connection, and simultaneously in order to guarantee that Moving plate 2 can rotate in a circumferential direction flexibly, need install bearing 4 additional in the Moving plate of air throttle 2 both sides, and strict control gap when mounted.Moving plate 2 is realized the adjusting to Moving plate 2 by drive unit syndeton 3.
In order to bear the High Temperature High Pressure exhaust of testpieces outlet, this structural member adopts exotic material to carry out monoblock cast.The deflation area of the air inlet face of Moving plate 2 and quiet dish 1 is designed to the rounding conical surface, can improve the mobility of Compressor test part exit flow, reduces the pressure loss, reduces the impact of exit flow to exhaust restriction means.Meanwhile, for guaranteeing that this restriction device can reach full closing state, Moving plate 2 jams block quiet dish 1 spatial area completely, in the time of the dynamic and static dish 1 of design processing, should be noted that controlling its ventilation area is slightly less than corresponding jam area.
After the utility model is applied on compressormeter, improve testpieces " cavity volume effect " impact on testpieces and testing equipment in the time entering unsteady-stage conditions in process of the test, and the Compressor test part surge frequency true and accurate more of test admission.Simultaneously, after having transformed, more accurate to the degree of regulation of testpieces discharge state in test, Moving plate 2 can be realized the adjusting of minimum 0.2 degree, improve the effective rate of utilization of test period and the work efficiency that test is prepared, and the performance parameter of the rotating speed line such as whole piece that can more complete full and accurate admission Compressor test part.In a word, the utility model is reasonable to the improvement of compressormeter exhaust structure, effective.
