Description
Technical field
The present invention relates to compressor detection fields more particularly to a kind of simple magnetic flux detection apparatus and magnetic flux to detect work
Skill.
Background technique
With the requirement of global climate warmed and people improve quality of life, Refrigeration Technique obtains in people's lives
To applying more and more widely.Compressor is the heart of refrigeration system, and variable-frequency motor is the power producer of compressor.Frequency conversion
The magnetic flux size of the electromechanical machine of air-conditioning contracting is affected to compressor performance, and therefore, it is necessary to the magnetic flux to electric moto used in compressor
It is detected, the motor magnetic flux amount detection on ordinary meaning is carried out mainly for rotor.
As shown in Figure 1, compressor is mainly made of several components such as the pump housing, shell and rotor, it is first in compressor assembly
First rotor is set in the shaft of the pump housing, is then packed into shell as a whole, and and case weld.
There are mainly two types of for the characterization processes of air conditioner motor magnetic flux：
1, it before rotor and pump housing assembling, individually magnetizes to rotor, surveys magnetic flux.The detection mode because test object is clear,
There is no the interference of the pump housing and shell, testing result accuracy is fine.But due to being usually that interference is matched between rotor and pump housing shaft
Close, rotor during assembly through frequently with heat expansion technique, and rotor assembly detect after with strong magnetic, heat will cause and disappear
Magnetic, so rotor can only carry out the cold setting technique such as tapping, and assembly difficulty greatly improves after using the characterization processes.In addition,
Rotor assembly can inevitably adsorb sundries during assembling with the pump housing, cause detrimental effects to compressor performance.
2, magnetic flux detection is carried out after compressor assembling, although which solves exists in the first detection method
Various problems, but because in detection method usually using compressor electric motor carry coil detected, magnetic flux check when
Detector needs to be connected with the compressor coil being completed one by one, has certain damage to compressor coil pins, causes quality
Hidden danger, and the number of turns and the possible difference of specification due to motor difference coil, the processing of testing result is complex, needs to use
Detection device type it is also more.Meanwhile after complete machine assembling, once detection magnetic flux is unqualified, compressor can not be reprocessed, can only
Complete machine scraps processing, is unfavorable for reducing production cost.
