Description
Technical field
The utility model is related to testing equipment correlative technology field, and in particular to a kind of novel pressure Pulse Cyclic Tests are set
It is standby.
Background technology
Pressures cycle fatigue pulse test bench be for automobile brake pipe, inlet manifold, steering tube, fuel pipe, air-conditioner pipe,
The vapour vehicle component such as cooling water pipe, radiator pipe, hot air hose, cleaner and cleaner pipe, turbocharger pipe carries out pressure
Fatigue test, a kind of now widely used test method is that tired pulse reality is carried out by using electrohydraulic proportion technology
Test, this method is mainly adjusted by the valve port opening of proportional pressure control valve to control the pressure of test specimen appearance intracavity liquid various to simulate
Cycle pressure signal (such as sine wave, triangular wave), so as to carry out multiple compression shock to examine its fatigue behaviour to test specimen.
In electro-hydraulic proportional control system, widely used control strategy is PID control at present, and it has, and simple in construction, stability is good, work
The advantages of making reliable, easy to adjust.
The pressure test equipment of existing product is exactly mainly to be required according to standard with certain high-low pressure scope, and with one
Determine the pressure pulse test equipment of some cycles number test of pulse frequency progress.But the problems existed, for example：(1)、
It is typically only capable to once do the experiment of a sample, so needs to consume the longer time if it need to make one group of 2 to 3 sample
Experiment can be completed, if doing 100,000 experiment, then needs continuously to run 28 hours for 60 times per minute, 3 examinations is done respectively
Sample will 84 hours, it is clear that efficiency still has much room for improvement；(2), process of the test does not have the real time data of pressure record, as a result only has
Whether the number of times result of numerical monitor, does not illustrate dynamics sufficiently for test result, really carried out for process of the test
Actual test can not carry out inquiry and review.
Utility model content
The purpose of this utility model be in order to make up the deficiencies in the prior art there is provided one kind it is simple in construction, can be while entering
The novel pressure Pulse Cyclic Tests equipment of the multiple specimen tests of row.
In order to reach the purpose of this utility model, technical scheme is as follows：
Including air inlet pipe, air intake control valve, control cabinet, escape pipe and test fixture, air inlet pipe one end connection source of the gas,
The other end connects and is provided with pressure monitoring device, impulse generator and counter, the one of escape pipe on air intake control valve, control cabinet
End is connected with air intake control valve, the other end and test fixture are connected；One end of air intake control valve is provided with adjusting knob, air inlet control
Digital display meter is provided with the upside of valve.
Preferably, there are multiple mounting holes on described test fixture side by side, multiple mounting holes are sequentially communicated, and can be entered simultaneously
The pressure pulsing cycles experiment of the multiple samples of row.
The utility model has the advantage that：
Simple in construction, reasonable in design, convenient reading and multigroup experiment can be carried out simultaneously, when saving substantial amounts of experiment
Between, test efficiency is substantially increased, saves manually, reduces energy consumption.

Embodiment
The utility model is further described with reference to embodiment, but protection domain of the present utility model not only office
It is limited to embodiment.
With reference to shown in Fig. 1-Fig. 4, a kind of novel pressure Pulse Cyclic Tests equipment, including air inlet pipe 1, air intake control valve 2,
Control cabinet 3, escape pipe 5 and test fixture 6, the one end of air inlet pipe 1 connection source of the gas, other end connection air intake control valve 2.Control cabinet 3
On pressure monitoring device 8, impulse generator 4 and counter 9 be installed, pressure monitoring device 8 is used to detect the pressure on escape pipe 5
Power, impulse generator 4 is used to produce pulse, and counter 9 is used to count.One end of escape pipe 5 is connected, separately with air intake control valve 2
One end is connected with test fixture 6.One end of air intake control valve, which is provided with the upside of adjusting knob 11, air intake control valve, is provided with digital display meter
10, according to pressure monitoring device 8, the pressure on escape pipe 5 can adjust by adjusting knob 11.
There are multiple mounting holes 7 on test fixture 6 side by side, multiple mounting holes are sequentially communicated, and escape pipe 5 is only with therein one
Individual mounting hole 7 is connected, and test fixture 6 can carry out the pressure pulsing cycles experiment of multiple samples simultaneously.
Finally it should be noted that：Above example only not limits the utility model and retouched to illustrate the utility model
The technical scheme stated, therefore, although this specification the utility model is had been carried out with reference to each above-mentioned embodiment it is detailed
Illustrate, still, it will be understood by those within the art that, still the utility model can be modified or equally replaced
Change, and technical scheme that all do not depart from spirit and scope of the present utility model and its improvement, it all should cover new in this practicality
In the right of type.
