Using the method for being detected for motor controller sealing property and looking for leak source of the present embodiment, its operation principle is such as
Under (as a example by the detection of workpiece to be detected and looking for leak source)：
Preparation process：Water supply splenium part 1, supply splenium part 2 and detection part 3 are connected according to Fig. 2 (to be ensured to close
All valves and magnetic valve), during workpiece to be detected 6 accessed into detection part 3；The reading of all of digital display manometer B2 is detected,
Ensure its reading for 0 (if not zero, then the adjustment method with reference to existing digital display manometer carry out back to zero operation)；
Characterization processes are specifically：
The first step, the gas that the inside of workpiece to be detected 6 is full of specified pressure by supplying splenium part 2, specifically：Open
Air compressor 2.1, opens air flue total valve 2.2, the 4th magnetic valve A5, test total valve 4.1, the electricity of test valve A1 and first
Magnet valve A2 (ensures that the second magnetic valve A3 is closed), realizes the inner inflatable of workpiece to be detected 6 to certain pressure (this pressure
Setting value is determined according to actual conditions and actual product) the first magnetic valve A2 is closed afterwards (may be otherwise air compressor
2.1st, air flue total valve 2.2, the 4th magnetic valve A5, test total valve 4.1, test valve A1 and the first magnetic valve A2 are carried out simultaneously
Close), pressure sensor B1 is detected pressure value and is shown by digital display manometer B2 in reading part 3.13 by first pressure
Go out, obtain final product initial pressure data；By workpiece pressurize to be detected -5 minutes 1 second, (time of pressurize was also to be carried out according to actual conditions
Setting, general to use 30 seconds)；Pressure sensor B1 detects pressure value and leads to again in reading part 3.13 by first pressure
Cross digital display manometer B2 to show, obtain detecting pressure data；
Second step, will detection pressure data and initial pressure data be compared, if detection pressure data and initial pressure
Data are equal, then judge that workpiece to be detected is qualified products, and detection is completed；If detection pressure data is less than initial pressure data,
Then judge that workpiece to be detected is substandard product, after gas in workpiece to be detected is drained (specifically：Open the second magnetic valve
A3, other in workpiece to be detected 6 of draining about are vented -2 minutes 2 seconds, and the second magnetic valve A3 is without recovering extremely after the completion of exhaust
Closed mode)；Into looking for leakage technique.
The Lou technique is looked for be specifically：
Step a, (Ni is the 0.1- of the rated speed of motor in high-pressure hydraulic pump as Ni to set the rotating speed of motor inverter 1.3
0.8 times), wherein：I is natural number, and Ni gradually increases with the increase of i values；
Step b, by water supply splenium part by inside workpiece to be detected be full of water, specifically：Open (the electricity of high-pressure hydraulic pump 1.2
The rotating speed of the motor of the control high-pressure hydraulic pump 1.2 of machine frequency converter 1.3), open water channel total valve 1.4, the 3rd magnetic valve A4, test always
Valve 4.1, test valve A1 and the first magnetic valve A2 (ensuring that the second magnetic valve A3 is in opening), to workpiece to be detected 6
In be filled with water (pipeline where the second magnetic valve A3 there are flowing out -10 seconds 1 second and be defined) and close the second magnetic valve A3 afterwards (in order to enter
Row is repeatedly searched, and only needs to close the second magnetic valve A3 herein), leak source is searched, if finding out leak source, carry out leak source mark simultaneously
And detection of end and look for leak source to work；If not finding out leak source, next step is carried out；
Step c, i=i+1 is set, return to step a.
Using the system and method for being detected for motor controller sealing property and looking for leak source of the present embodiment, there is following
Several key points：
1st, system uses Modular Structure Design, saves equipment occupation space, and defective products is directly entered using dismounting is not required to
Enter to look for leak source technique, it is time-consuming.
2nd, pressure reading manner uses pressure sensor and digital display manometer in system, and accuracy is high, improves product qualified
Rate.
3rd, security performance is improved, it is ensured that applied environment is not caused using valve and the Combination Design of magnetic valve in system
Influence.
4th, system is combined using multiple detection single-pieces, can be carried with the detection of the multiple workpiece to be detected of all promising policy
High workload efficiency.
5th, leak source technique is looked for use Frequency Converter Control mode, specifically：The rotating speed of motor inverter is set from low to high, makes
Obtain high-pressure hydraulic pump output inner pipe water pressure to design from low to high, meet different demands and (be primarily due to：Leak source is too small, and infiltration is too
It is small to can't see, then start frequency converter power frequency pattern, leak source is searched again).
