Technical field
The present invention relates to compressor, specifically a kind of method of testing of compressor.
Background technology
Due to the singularity of compressor inner structure, rotor and stator are in the time of different angles, and the gap between it is also variant.Adopt traditional static insulating, withstand voltage test method, can not detect effectively reliably electric insulation, withstand voltage properties parameter accurately, cause erroneous judgement (unacceptable product is judged to certified products often).
Summary of the invention
The problem existing in order to solve prior art, the present invention proposes a kind of compressor that carries out dynamic insulation test and voltage-withstand test and turns stator dynamic testing method.
Object of the present invention realizes by following scheme:
A kind of compressor turns stator dynamic testing method, it is characterized in that, the method comprises the steps,
11). start compressor, deenergization after compressor operation is normal, opens air blowing solenoid valve in the moment of deenergization, and outside malleation air-flow is blown into from compressor air intake, promotes compressor inner rotator and continues rotation;
12). under the current intelligence rotating at above-mentioned rotor, carry out Insulation test and voltage-withstand test, test finishes to close air blowing solenoid valve.
And the method also comprises following testing procedure,
21). start compressor, make compressor operation, judge that whether electric current is normal, if electric current transfinites, point out error message, if electric current normally, enters next step;
22). vacuum tightness detects, if vacuum tightness detects the overtime designing requirement that do not reach, points out error message, if reach designing requirement, enters next step;
23). rotating speed reaches detection, if rotating speed does not reach designing requirement overtime, points out error message, if reach designing requirement, enters Insulation test and voltage-withstand test step.
The present invention is a set of method that can be used for scene and carry out compressor electrical insulation testing and voltage-withstand test, can realize the electric insulation between compressor inner rotator and stator, withstand voltage dynamic test, and can reach insulation, voltage-withstand test and running test does not interfere with each other, can effectively improve testing efficiency and reliability, reduce operation intensity, save human resources.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention process flow diagram.
Embodiment
Below in conjunction with drawings and Examples, the present invention will be described in detail.
As shown in Figure 1, the compressor that the present embodiment discloses turns stator dynamic testing method and in turn includes the following steps:
Start compressor, make compressor operation, judge that whether electric current is normal, if electric current transfinites, point out error message, if electric current normally, enters next step;
Vacuum tightness detects, if vacuum tightness detects the overtime designing requirement that do not reach, points out error message, if reach designing requirement, enters next step;
Rotating speed reaches detection, if rotating speed does not reach designing requirement overtime, points out error message, if reach designing requirement, enters next step;
Compressor power-off, opens air blowing solenoid valve in the moment of deenergization, and outside malleation air-flow is blown into from compressor air intake, promotes compressor inner rotator and continues, continues rotation;
Insulation test, if Insulation test does not meet designing requirement, points out error message, if normally, enters next step;
Voltage-withstand test, if voltage-withstand test does not meet designing requirement, points out error message, if normally complete whole test, closes air blowing solenoid valve.
In addition in above-mentioned Insulation test and voltage-withstand test, can carry out, simultaneously.
The present invention is in order to reach the dynamic insulation that can detect between compressor inner rotator and stator and dynamically withstand voltage, and voltage-withstand test and running test can not phase mutual interference, the moment of power-off after electric current, vacuum tightness and measurement of rotating speed complete, controlling air blowing solenoid valve opens, use outside malleation air-flow to be blown into from compressor air intake, promote compressor inner rotator and continue to continue rotation, and control dielectric voltage withstand meter simultaneously and test, make it to reach the effect of dynamic insulation resistance and dynamic resistance test.
The control of this method of testing adopts the FX1N-60MR of Mitsubishi type Programmable Logic Controller (PLC), take PLC as control core, 7410 type safety dielectric analysis instrument (dielectric voltage withstand meter) and the frequency-variable controllers of arranging in pairs or groups, for detection of the revolution electric current of compressor, running speed, vacuum tightness, dynamic insulation resistance, the dynamic parameter such as withstand voltage.The method is a set of effective ways that carry out compressor electric insulation and withstand voltage properties detection for scene, can realize the electric insulation between compressor inner rotator and stator, withstand voltage dynamic test, and can reach insulation, voltage-withstand test and running test does not interfere with each other, native system is applied to scene can effectively improve testing efficiency and reliability, reduce operation intensity, save human resources.
The above embodiment has only expressed embodiments of the present invention; it describes comparatively concrete and detailed; but can not therefore be interpreted as the restriction to the scope of the claims of the present invention; in every case the technical scheme that adopts the form that is equal to replacement or equivalent transformation to obtain, within all should dropping on protection scope of the present invention.
