Swift and violent development, the producer for producing screw compressor is more and more, but product quality is also very different.Manufacturer at present
Main factory testing is by screw compressor suction and discharge value, power consumption, refrigerating capacity still by refrigeration system or performance detection stand
To determine whether qualification.Some screw compressors can reach performance standard, but noise and vibration are especially big, illustrate certain fortune
Dynamic component cooperation there is a problem.If without timely investigating, market is direct plungeed into, the vortex that those cooperations go wrong
Compressor abrasion is especially fast, it is easy to scrap or even can pollute air-conditioning system, it is inadequate to rely solely on single detection method
's.Therefore, in order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of manufacture Acoustic detection sides of screw compressor
Method.
Invention content
The purpose of this utility model is that solve the problems, such as techniques discussed above, provide and a kind of utilize Acoustic detection, a side
Face can determine whether screw compressor manufacture is qualified；Which on the other hand occur by noise figure come the specific component of accurate discrimination
Problem, so as to reduce detection time, convenient for the screw compressor manufacture acoustics inspection of the recycling repair of scroll compressor components
Examining system, technical solution are as follows.
Screw compressor manufacture acoustic testing system, it is special including screw compressor, condenser, throttling set, evaporator
Sign is, acoustic detecting device is provided at screw compressor side, and it is pre- to be equipped with noise figure in the acoustic detecting device
If module and fault detection module, noise figure presetting module can established standards noise figure for detecting whether screw compressor closes
Lattice, fault detection module can detect the operating status of each part in screw compressor by collection to noise figure, analysis；
Acoustic detecting device detects noise figure during screw compressor operation, the noise figure detected and noise figure presetting module phase
Obtained after comparison whether normal operation；After detecting that operation is abnormal, fault detection module starts, to the noise figure that detects into
Row further analysis determines the specific part of generation failure by different noise figure preset in fault detection module.
Preferred embodiment is that the fault detection module includes acoustic energy resonance amplifier, collector, wave filter, multichannel
Amplitude comparator.
Preferred embodiment is that the side of the condenser is provided with cooling system detection device.
Screw compressor manufacture acoustic testing system provided by the utility model, when in use, first in noise figure
Normal noise value range during screw compressor work is set in presetting module.It can be set according to different screw compressors
Different noise figures.Noise figure range when each part of screw compressor breaks down is preset in fault detection module.Sound
When detection device detects noise figure when screw compressor works, the noise figure detected is preset mould with noise figure first
Setting value in the block compares and analyzes, and show whether screw compressor operation is normal.If normal, screw compressor meets
It is required that.If abnormal, fault detection module starts, and the noise figure detected can be carried out with the setting value in fault detection module
Analysis comparison, so as to show which specific part goes wrong.
The beneficial effects of the utility model are：On the one hand it can determine whether screw compressor manufacture is qualified；On the other hand
Which gone wrong by noise figure come the specific component of accurate discrimination, so as to reduce detection time, convenient for screw compressor
The recycling repair of part.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the schematic diagram of acoustic detecting device.
Specific embodiment
With reference to Fig. 1 and Fig. 2 specific illustrative embodiments：
As depicted in figs. 1 and 2, screw compressor manufacture acoustic testing system, including screw compressor 1, condenser 2, section
Device 3, evaporator 4 are flowed, acoustic detecting device 5 is provided at 1 side of screw compressor, is set in the acoustic detecting device
Have noise figure presetting module and a fault detection module, noise figure presetting module can established standards noise figure for detecting scroll compression
Whether machine is qualified, and fault detection module can detect each part in screw compressor by collection to noise figure, analysis
Operating status；Acoustic detecting device detects noise figure during screw compressor operation, the noise figure and noise figure detected
Presetting module obtained after comparing whether normal operation；After detecting that operation is abnormal, fault detection module starts, to detecting
Noise figure be further analyzed, by different noise figure preset in fault detection module come determine generate failure tool
Body part.
Preferred embodiment is that the fault detection module includes acoustic energy resonance amplifier 6, collector 7, wave filter 8, leads to more
Road amplitude comparator 9.
Preferred embodiment is that the side of the condenser is provided with cooling system detection device 10.
Screw compressor manufacture acoustic testing system provided by the utility model, when in use, first in noise figure
Normal noise value range during screw compressor work is set in presetting module.It can be set according to different screw compressors
Different noise figures.Noise figure range when each part of screw compressor breaks down is preset in fault detection module.Sound
When detection device detects noise figure when screw compressor works, the noise figure detected is preset mould with noise figure first
Setting value in the block compares and analyzes, and show whether screw compressor operation is normal.If normal, screw compressor meets
It is required that.If abnormal, fault detection module starts, and the noise figure detected can be carried out with the setting value in fault detection module
Analysis comparison, so as to which 0 show which specific part goes wrong.
Therefore the device is preferably needed through a small-sized sound insulation frame noise of healthy compressor between 58db_70db
11, and be installed on floating anti-vibration platform 12, it is assumed that compressor setting speed is 4000rppm, the vibration frequency of each component of motor
Must be fundamental frequency and frequency multiplication, closer to fundamental frequency, its vibration amplitude is higher, and the acoustic energy resonance amplifier of acoustic detecting device is installed
Onto float plate, composite signal is obtained by collector, composite signal can be detached by digital filter and bandpass filter
Go out various acquisition pulses, by multichannel amplitude comparator compare reference signal can Judging fault point, which can also sentence
The missing of movement parts improves product quality in other assembling process.
