Be provided with the sound-absorbing silk floss in the middle of described latticed housing 110 and Qianmen 108, back door, the side door 109.
Described compressor A112 and compressor B113 are a kind of special compressor, promptly are the types by our requirement appointment, will take down slide plate in the compresser cylinder, and keep rotating shaft sufficient lubrication, compressor customized; Described compressor has three terminal U ends, V end, W end.
Now adopt special compressor to be contained in the testing arrangement casing, through cooling and noise reduction process replaced the frequency changer complete machine operation of the square wave driving of prior art afterwards automatically, promptly when the test controller logic function, need only control panel and special compressor operating, the testing arrangement case has been installed the compressor operating indicator lamp, very the intuitive judgment compressor is opened and is stopped, and connects electrician's instrument and can also see the compressor operating frequency.Do not need machine system to put into operation, just can finish the controller function logic testing.Two specific compressors (convenient test one drags many outer machines that the refrigeration system of two compressors is arranged) are installed in the testing arrangement case, and two compressors work alone.And assemble various parts realization testing arrangement casings and can lower the temperature automatically and decrease of noise functions, make the testing arrangement casing can substitute the task that machine system carries out the controller logic test.Installed monitoring compressor surface temperature controlling device in the testing arrangement casing, by the temperature in two 8 numeral demonstration compressor operatings, when the surface temperature of compressor reaches set temperature value, the radiator fan that is installed in the testing arrangement top this moment brings into operation, after having only the compressor surface temperature to drop to a certain setting value, radiator fan quits work.Stick the sound-absorbing silk floss at testing arrangement chamber interior wall grid, reduced the noise in the compressor operating.Testing arrangement inner part explanation: 101, the loam cake of testing arrangement; 102, compressor A earth leakage circuit-breaker is positioned at the upper end left of loam cake, prevents that under the abnormal conditions, electric current is too high during compressor operating, the protection compressor; 103, compressor A indicator lamp is positioned at compressor A earth leakage circuit-breaker next door, and this indicator lamp is bright when compressor operating, and this indicator lamp did not go out when compressor did not move; 104 numeric display units show compressor A, B temperature, are positioned at the loam cake the top; 105, radiator fan, be positioned at numeral show compressor A, B temperature under, when the temperature of compressor reached certain setting value, radiator fan was opened, when temperature dropped to setting value, radiator fan was out of service; 106, compressor B earth leakage circuit-breaker, the upper end that is positioned at loam cake is right-hand, prevents that under the abnormal conditions, electric current is too high during compressor operating, the protection compressor; 107, compressor B indicator lamp is positioned at compressor B earth leakage circuit-breaker next door, and this indicator lamp is bright when compressor operating, and this indicator lamp did not go out when compressor did not move; 108, the convenient fixedly sound-absorbing silk floss in back is opened at Qianmen; The back door also can be opened, and acts on same Qianmen; 109, left and right sides side door can be opened, and acts on same Qianmen; 110, latticed housing is a grid around the testing arrangement, and effect is fixing sound-absorbing silk floss all around; 111, roller, makes things convenient for moving of testing arrangement by totally four; 112, compressor A places fixing compressor A, is positioned at the testing arrangement bottom; 113, compressor A places fixing compressor A, is positioned at the testing arrangement bottom.
When square wave drove the functional test of class frequency changer controller logic, complete machine need not be taken over, and the complete connection of electrical appliance part, promptly allow the controller part by normally devoting oneself to work, and components of system as directed was not opened.But controller work needs compressor operating, and extract three phase lines of being defeated by compressor from IPM in the model machine this moment, replaces with the testing arrangement case of above-mentioned assembling, connects that arbitrary compressor can replace complete machine to move in the testing arrangement case.Compressor need the power function of competence exertion semi-intelligent control of the controller of back testing arrangement case that puts into operation.In the test process when hear that buzzer ticks-ticks in the testing arrangement case-drip three, illustrate that then the compressor operating temperature reaches the heat extraction condition, air outlet was swept the wind lid and was opened this moment, fan is opened operation and is given case interior heat extraction.Automatically close when temperature drops to the certain condition fan, sweep the wind lid and automatically reset closed every making an uproar.When hearing that buzzer ticks-ticks, tick-tick ... there is the operating temperature of compressor to reach the higher temperatures condition in the explanation case when piping continuously, air outlet was swept wind lid and was opened this moment, fan is opened operation and is also ticked-tick for the interior heat extraction of case simultaneously, tick-tick ... call user's attention continuously pipes, if the temperature inside the box is reduced under the rated condition, then can stop automatically piping and close fan automatically, sweep the wind lid closure that automatically resets.Then need artificial the processing if be in alarm condition for a long time.Open case lid or out of service, allow case inner compressor Automatic fan heat.If long-time warning the, temperature continue to rise, last compressor can be shut down by overload protection, and ordinary circumstance is difficult to reach this condition.When electric leakage or short circuit phenomenon occurring in the testing arrangement use, leakage switch will play a protective role.Compressor can't be opened if problem is untreated then.When test during different type of machines, need the identical compressor of standby other important technological parameters,, then can on machine capacious or little machine, all can use with a series of compressors as same producer.Wherein major parameter is meant a grade logarithm, coil resistance and inductance etc.
Use this testing arrangement, safeguard and lack, general need be regularly to the compressor apply oil, the dust of coming in bits at the bottom of the wash-up tray and inlet scoop, and leakage switch regularly detects, and meets the requirements to come into operation.Through many-sided verification experimental verification, utilize this testing arrangement test result to meet the result of system test fully.
Above-mentioned listed specific implementation is nonrestrictive, and to one skilled in the art, in not departing from the utility model scope, various improvement and the variation carried out all belong to protection domain of the present utility model.
