Recently as the development of domestic air mail industry, the implementation phase that army/civil engine Project R&D work coming into through engineering approaches, the pre research work of the aero-engine with higher performance and design level is also carried out in synchronization. Compressor is as one of the three big critical components of aero-engine, have designing technique complexity, develop difficulty big, technical risk high, therefore, Test And Research Work carried out by special compressormeter, for compressor design verification and improvement remodeling, accelerate through engineering approaches development paces and there is important function.
At present, the exhaust apparatus of most of compressormeters adopts big volume or the catcher with adjustment sheet, both frame modes there is problems in that 1 in concrete test use procedure) vessel manufacture causes testpieces outlet to produce amplitude, low-frequency high-energy gas, affect experimental safe, also result in the admission result distortion of compressor surge border; 2) add exhaust duct axle system length, cause that equipment first critical speed is too low, limit test effective range; 3) runner moulding is simple, and pressure at expulsion loss is big, is unsatisfactory for the test requirements document of low pressure ratio piston mechanism of qi testpieces; 4) exhaust apparatus manufactures material and is generally ironcasting, and heat resisting and pressure resisting ability is poor, is unsatisfactory for the high-power high voltage test requirements document than Compressor test part.
Summary of the invention
The purpose of this utility model: the exhaust apparatus that this utility model provides, purpose is in that to reduce delivery space, shortens exhaust duct axle system length, reduces pressure at expulsion loss and improve heat resisting and pressure resisting ability, the final trial stretch improving compressormeter and experimental safe operational reliability.
Technical scheme: a kind of exhaust apparatus for axial flow compressor exerciser, is characterized by: described exhaust apparatus includes exhaust collector 1 and exit casing 2, and exhaust collector 1 is annular housing, and annular housing has air vent; Exit casing 2 includes exhaust duct 3 and power installation cavity 5, and the exhaust duct 3 of exit casing 2 connects with the cavity of exhaust collector 1, is provided with power transmission in power installation cavity 5.
As a kind of improvement of the technical program, in exit casing 2, the import department of exhaust duct 3 is provided with aerofluxus governor motion 4. Aerofluxus governor motion 4 is arranged on the import department of exhaust duct 3, exhaust chamber effect can be effectively reduced.
Beneficial effects of the present invention: the technical program improves the accuracy of Compressor test measurement performance parameter, it is possible to provide more efficiently test data support for Capability of Compressor assessment and Curve guide impeller; Improve compressormeter overall safety reliability of operation, reduce further empirical risk, it is ensured that test effective percentage; Extend the original trial stretch of exerciser, meet low aerofluxus flow resistance loss and the resistance to pressure request of high-temperature resistant simultaneously, exerciser can be made to meet the aero-engine development in following 10��20 years needs to Compressor test research, reduce the input cost of newly-built exerciser, comprehensively improve the test capability of domestic air mail engine compresses parts.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the technical program is described in further detail.
As illustrated in fig. 1 and 2, exhaust apparatus is mainly made up of exit casing 2 and exhaust collector 1 two parts, and exhaust collector 1 is annular housing, and annular housing has air vent; Exit casing 2 is arranged in the annular housing of exhaust collector 1, exit casing 2 includes exhaust duct 3 and power installation cavity 5, the exhaust duct 3 of exit casing 2 connects with the cavity of exhaust collector 1, and the radial direction aerofluxus of engine compresses parts transfers horizontal direction discharge to the most at last.
Forming as it is shown on figure 3, exit casing 2 adds for the strong rustless steel casting idiosome machine of heat, casing has two passages, and outer tunnel is exhaust duct 3, and internal channel is power installation cavity 5. Exhaust duct 3 is made up of straight section and two sections of gas channels of turnaround section, straight section purpose of design is so that engine compresses knockdown export axial flow gentle transition slows down, thus reducing the airflow pressure losses of turnaround section, turnaround section purpose of design is that the air-flow making axially flowing transfers Radial Flow air-flow to.
As it is shown on figure 3, be provided with power transmission in exit casing 2 power installation cavity 5, aerofluxus governor motion 4 is arranged on exhaust duct 3 porch of exit casing 2, installation site next-door neighbour's engine compresses part exhaust end, makes exhaust chamber volume significantly reduce; In the power installation cavity 5 of exit casing 2, processing has the forward and backward bearing mounting base of exhaust shaft system, drive shaft system is arranged in the power installation cavity 5 in exit casing 2 by axle bearing, drive shaft system input adopts diaphragm coupling to be connected with clutch end, drive shaft system outfan adopts ball-head cover tooth be connected with engine compresses part input or be connected with suspension type gear-box, it is to avoid the axial force between rotating shaft is transmitted mutually.
As shown in Figure 4, exhaust collector 1 is welded for stainless steel materials panel beating, and catcher is arranged on exit casing 2 turnaround section, passes through Flange joint. Exhaust collector 1 have employed big volume catcher in design, effectively reduces aerofluxus crushing, and flow channel cross-section is uniform flow cross section, it is ensured that the uniformity in flow field.
After the present invention applies on compressormeter, effectively improve the accuracy that compressor surge dynamic parameter gathers, meet the test requirements document of compressor low-pressure ratio operating mode and high pressure ratio operating mode simultaneously, substantially expand the efficiency test working range of compressormeter, it is ensured that carrying out smoothly of many types of axial flow compressor testpieces performance test. Meanwhile, through prolonged and repeated operation and test examination, the compressormeter axle system running status adopting this improvement exhauster structure is good, significantly improves safety and the effective percentage of test. In a word, the present invention is reasonable to the improvement of axial flow compressor exerciser exhaust apparatus, effective.
