Abstract
The invention discloses an emergency stop control method for an engine. The emergency stop control method for the engine is used for performing emergency stop under a runaway emergency condition of the engine in an experimental process. The emergency stop control method for the engine comprises the following steps: (1) the engine is run; (2) when a revolution speed transducer detects that the revolution speed of the engine exceeds a first preset value, a test control system determines that the engine is abnormal and sends an instruction to a pneumatic stop valve to execute a close action, gas inflow of the engine is cut off, and the engine is forced to stop, wherein the pneumatic stop valve is arranged between an intercooler and the engine. Therefore, according to the emergency stop control method for the engine, the engine is stopped faster through cut-off of gas inflow of the engine, and harm caused by long-time high-speed operation of the engine is avoided to the greatest extent.
Description
Technical field
The present invention relates to a kind of motor in process of the test, occur that driving in emergency circumstances carries out the anxious controlling method of stopping of engine emergency.
Background technique
A R & D design new engine out has to pass through stand test to verify its reliability, Economy, power character and emission compliance situation, in whole test development process, new architecture be attended by some unsafe factors as: temperature is high, leakage of oil, driving etc. factor.Mostly engine shutdown is forced by the oil circuit, power measurer application of load, automatically controlled type restriction oil mass etc. cut off outside stand in mode in the past, bavin is also had to consider device or pipeline trapped fuel owing to cutting off oil circuit rear engine itself, be enough to allow motor in high speed, run slightly long a period of time, now motor is by well damage, What is more component driving, causes great destruction to test instrument etc.
The information being disclosed in this background technique part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide the anxious controlling method of stopping of a kind of engine emergency; reach motor by the air inlet (cut off air to block burning) cutting off motor to shut down more fast, farthest avoid the engine long time to run up the harm brought.
For achieving the above object, the invention provides the controlling method that a kind of engine emergency urgency is stopped, in order to occur in experimentation that at motor the urgent urgency of in emergency circumstances carrying out of driving is stopped.The anxious controlling method of stopping of engine emergency comprises following steps: (1) makes motor run; (2) when speed probe detects the rotating speed of motor more than the first predetermined value, then test control system determination motor occurs abnormal, and this test control system sends instruction performs closing motion to pneumatic cut-off valve, cut off the air inlet of motor, force engine shutdown; Wherein, pneumatic cut-off valve is arranged between intercooler and motor.
Preferably, in technique scheme, the anxious controlling method of stopping of engine emergency also comprises: when speed probe detects the rotating speed of motor more than the second predetermined value, then test control system sends alarm signal, cause operator to note, wherein this second predetermined value is less than the first predetermined value.
Preferably, in technique scheme, test control system comprises emergency stop button, closes pneumatic cut-off valve, thus cut off the air feed to motor by automatic or this emergency stop button of manual operations.
Compared with prior art; the present invention has following beneficial effect: the anxious controlling method of stopping of engine emergency of the present invention; the air inlet (cut off air to block burning) of fast shut-off motor can reach motor and shut down more fast, farthest avoid the engine long time to run up the harm brought.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the anxious controlling method of stopping of a kind of engine emergency according to the present invention.
Main Reference Numerals illustrates:
1-motor, 2-intercooler, 3-test control system, 4-speed probe, the pneumatic switching valve of 5-, 6-emergency stop button.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
Clearly represent unless otherwise other, otherwise in whole specification and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or constituent element, and do not get rid of other element or other constituent element.
As shown in Figure 1, according to the controlling method that a kind of engine emergency urgency of the specific embodiment of the invention is stopped, in order to occur in experimentation that at motor the urgent urgency of in emergency circumstances carrying out of driving is stopped.The anxious controlling method of stopping of engine emergency comprises following steps: (1) makes motor 1 run; (2) when speed probe 4 detects the rotating speed of motor 1 more than the first predetermined value, then test control system 3 determines that motor occurs extremely, and this test control system 3 sends instruction performs closing motion to pneumatic cut-off valve 5, cut off the air inlet of motor 1, force motor 1 to stop; Wherein, pneumatic cut-off valve 5 is arranged between intercooler 2 and motor 1.
The anxious controlling method of stopping of engine emergency also comprises: when speed probe detects the rotating speed of motor more than the second predetermined value, then test control system 3 sends alarm signal, causes operator to note, wherein this second predetermined value is less than the first predetermined value.
Test control system 3 comprises emergency stop button 6, closes pneumatic cut-off valve 5, thus cut off the air feed to motor 1 by automatic or this emergency stop button 6 of manual operations.
In test process: when motor 1 is subject to suddenly the impact of certain factor, cause that debugging is out of control to run up when exceeding the performance boundary of design own, when speed probe 4 detects the rotating speed of motor 1 more than the second predetermined value, test control system 3 is gone out extremely by the Parameter analysis that comparative analysis system itself is arranged, tentatively judge that exception occurs motor 1, first releasing alarm signal causes operator to note, when motor 1 rotating speed continue to rise to reach the first predetermined value time, then send the instruction of execution emergency treatment and perform closing motion to pneumatic cut-off valve 5, pneumatic cut-off valve 5 causes the air inlet entered in motor 1 firing chamber to be isolated at short notice after closing, motor 1 is forced to realize when burning cannot be performed shutting down, thus reduce the complete machine or damage of components that cause due to controlled exception and part and fly out and destroy equipment and instrument around.When performing a test, tester also manual operations can close pneumatic cut-off valve 5 by emergency stop button 6, thus cuts off the air feed to motor, forces motor 1 to realize when performing burning shutting down.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
