The working principle of the invention and process for using: after the present invention installs,
1, PWM valve testing button 22 is selected before operating system, PWM frequency, pressure and PWM fundamental frequency, width sets exist
On main panel, if being 0 without using fundamental frequency pulsewidth is set if fundamental frequency, PWM valve testing button 22 is clicked, pop-up dialog box:
Since PWM operation be gradually increased to maximum pulse width by stepping-in amount through stepping time originating pulsewidth, then is gradually reduced
To pulsewidth is terminated, operation is completed.Stepping-in amount is smaller, and measurement points (resolution ratio) are higher, and stepping time is bigger, and measurement data is more quasi-
Really.
Output maximum pressure data are 35MPa, cannot be changed.It is arranged according to the flow of required test pressure and valve body
It shows pressure peak and display flow peak, curve is made to reach best considerable effect.
When operation, PLC one point of every completion notes that host computer, and host computer, which is read, to be completed to be shown on curve.Main panel
On current pressure and present flow rate be current actual value.
2, overflow valve test
It selects operating mode for overflow valve test, clicks overflow valve parameter button 22 and parameter is set, system pressure is by ratio
Overflow valve generates, and proportional overflow valve control output 100~800mA electric current just generates the pressure of each consecutive variations to proportional pressure control valve
Power.Testing maximum pressure is protection pressure, that is, pressure upper limit.
Referring to the above parameter, the output of proportional overflow valve control begins to pass through stepping time by stepping-in amount gradually from 100mA
Increase, until flow reaches, flow value 10L/min (fully opening) is completed in overflow or pressure reaches maximum pressure 5.0MPa,
Electric current is gradually decreased again, until pressure, to 0.35MPa, test terminates.
It is to compress to unclamp oil cylinder pressure that release, which is compressed, with output.
3, testing fatigue
Testing fatigue parameter setting and test value are all on the home panel.
Under auto state, operating mode is chosen, clicks system stop button 22, pops up start and stop dialog box, selection starting
Or stop, " determination " is pressed, system is started or stoped.
4, impact operation:
It when system is not run, by lower button 22, brings into operation according to institute's setting parameter, surge is that valve compresses release
Use pressure.
5, adjustment parameter:
First three parameter is about oil pressure cntrol, and the proportional overflow valve of oil pressure is generated, exported by proportional pressure control valve amplifier
Current control, since pressure control response is than very fast, so being controlled using general PI, parameter does not have to change.
Behindness parameter is controlled about oil circuit temperature, and oil heater is controlled by the 3 phase solid-state relays with zero passage, zero electricity
Press off logical, zero current is closed, and control solid-state relay opens the output power of pulse-width controlled heater.Start constant temperature to click, bullet
Dialog box is as follows out, clicks starting, starts constant temperature.It clicks and presses the above parameter, it is assumed that the setting oil circuit temperature on main panel works as perseverance
Startup temperature moment exports 30% power；Assuming that actual temperature exports %20 when being greater than 40.5 DEG C, 10% is exported when greater than 46 DEG C,
Output is closed when greater than 45 DEG C, is exported 40% when less than 39 DEG C, when being output 60% less than 37 DEG C, is exported when less than 35 DEG C
100%.
Open prior document:
In the case where system does not have automatic running, opening file, (the entitled .ylll of suffix, automatic running complete automatic protect
There are under E disk yldata catalogue), curve is shown according to the supplemental characteristic for opening file, after opening file activities, can also be opened
Three files are shown on screen in graph form, note: being opened the maximum pulse width compared and be preferably equal to open the maximum arteries and veins of file
Width cannot be greater than.
Export, importing Excel file automatic running completion can export test data to Excel file.It can import
In the Excel file to screen for the standard component crossed after tested, as comparison curves, upper lower deviation is arranged in Excel file, does not conform to
Lattice product, pop-up dialog box alarm.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
