Description
Technical field
The present invention relates to a kind of rotary fluid mechanical performance tester, particularly a kind of have in conjunction with the network telemetry remote control, is beneficial to performance data and measures and the rotary fluid mechanical performance tester of putting in order.
Background technology
Rotary fluid machine as various fan, fan blower, pumping, turbine, injection engine, can provide functions such as energy conversion or mass transport, is very important industrial products therefore.With the highest running efficiency (Effciency), satisfy the demand of energy conversion or mass transport, be the primary target of pursuing of rotary fluid machine engineering design.Yet, during the rotary fluid machine running, the flow field that the feasible fluid therebetween of the relative motion of stator and rotor must produce non-permanent (Unsteady) changes, and produce the non-permanent acting force act on quiet, the moving vane, this calls stator-rotor reciprocation (Stator-RotorInteraction).This reciprocation may cause the structural fatigue of rotary fluid machine to destroy, and is that the fluid mechanics designing institute must be removed or reduce, and also is that the structural mechanics designing institute must overcome.In addition; rotating machinery periodically moves, and flow field periodicity and aperiodicity pressure change around causing, and this pressure change propagation is in air; promptly be annoying noise, this also is that the design engineer faces the problem that environmental protection, client complaint and product competition institute must solutions.Though rotary fluid machine is very huge industry, in each specific products field, various abundant materials, assembly, structure, manufacturing, system, testing research development and technology have been accumulated; But because the complicacy of fluid motion and the difficulty of Theoretical Calculation, make the fluid motion relevant design of rotary fluid machine, efficient, destruction, noise etc. still mainly depend on a large amount of experimental measurements and experience as the aforementioned, also therefore become expensive technology (Know-How).
Hydrodynamic force is calculated based on basic mechanics principle, development of effective numerical computation method (Numerical Scheme) and physical model (Physical Model), with at a high speed COMPUTER CALCULATION emulation and analysing fluid motion and the influence that produces thereof, be unusual important field of research.Calculate by hydrodynamic force, experimentize, and carry out graphics process and data present with computing machine in virtual mode; Not only can avoid (can save at least) expensive experimental equipment and measurement, and be easy to obtain understanding the behavior of whole flow field, so to some extent according to designed improvement, be many research units and design engineer's expectation always.Yet late to today, because the non-linear dynamic behavior of fluid motion, the validity of hydrodynamic force computing method and the reliability of result of calculation are still quite limited.The hydrodynamic force of rotary fluid machine is calculated, though since ardent demand, the input of existing quite huge resources for research, and owing to be subject to the computer computation ability deficiency, research in the past is all based on permanent (Steady State) flow field analysis.With whole rotary fluid machine is object, comprise the non-permanent interactive drag flow field flow body Cable Power Computation of stator and rotor, can calculate the variation of suffered oscillation force of physical construction and pressure wave, making is enough to evaluation structure life-span and noise, is still quite rare.
See also known rotary fluid mechanical performance tester shown in Figure 1 (U.S. Pat 6298718) synoptic diagram.This proving installation has the turbocharger 15 of a reciprocating engine 10 and a combination, the turbocharger 15 of this combination has a turbine 16, this turbine 16 connects a turbine guide rod 18 to drive a compressor 17, after it provides gas to this compressor 17 to be compressed into gases at high pressure by an air intake vent 22, with an inlet air manifold 24 gases at high pressure are directed to this reciprocating engine 10, with this reciprocating engine 10 with fuel and gases at high pressure mixed combustion, promote this turbine 16 with an exhaust manifold 20 more at last and carry out output work, and after the more unnecessary gas of this exhaust manifold 20 being imported this inlet air manifold 24,, this reciprocating engine 10 carries out cycling and reutilization so that being provided by a by-path 26 and bypass control valve (BCV) 27.
More than this proving installation control this reciprocating engine 10 by a reciprocating engine control module 30 with a controller 32, at first this reciprocating engine control module 30 can be with a speed pickup 35, one temperature sensor 36 and a pressure transducer 37 detect temperature and the pressure that enters these compressor 17 air, to determine this air intake vent 22 to provide preferable gaseous state to this compressor 17, promote pressure transducer 39 by a gaseous mass flow rate sensor 38 that is arranged at this inlet air manifold 24 and again, enter the gaseous state of this reciprocating engine 10 with decision, the judgement software 45 that this reciprocating engine control module 30 has, this judgement software 45 can make the operator directly control with the detected value that a feature follower 47 provides observation and operation to revise the sensor.
Because this proving installation can only provide the sensing function of these compressor 17 inner airs (or gas) of turnover, so this proving installation only can be used to measure the performance of this compressor 17.Just say that also because this proving installation does not provide the sensing function of these turbine 16 internal gas of turnover, so do not having fully for turbine under the situation of any measurement data, this proving installation is the performance that can't be used to measure this turbine.In addition, because control this compressor back pressure with the by-pass valve method, can cause reciprocating type engine when low discharge, can't export enough power, accurately measure disappearances such as surge area characteristic, so how to go to solve the relevant defective of existing rotary fluid mechanical performance tester, be the rotary fluid mechanical performance test relevant dealer urgently remain scheme and the improvements seeking to solve.
