Description

Technical Field

[0001] The utility model relates to a noise inspection device, in particular to a noise inspection device for an air-conditioning compressor, belonging to the technical field of compressor noise detection. Background Technique

[0002] The air-conditioning compressor plays a role in compressing and driving the refrigerant in the air-conditioning refrigerant circuit. The air-conditioning compressor is generally installed in the outdoor unit. The air-conditioning compressor extracts the refrigerant from the low-pressure area, compresses it and then sends it to the high-pressure area for cooling and condensation. Heat is dissipated into the air through the radiator fins, and the refrigerant also changes from a gaseous state to a liquid state, and the pressure increases. After the compressor is produced, in order to detect the quality of the compressor, it is necessary to detect the noise of the compressor.

[0003] Among them, the "motor noise device" disclosed in the application number "202121057033.1" "includes a detection box, on both side surfaces of which decibel meters are embedded and installed, on the upper surface of the detection box near the two side edges, turning knobs are installed by threading, on the inner surface of the detection box near the center position, a sleeve rod is fixedly installed, on the inner surface of the detection box near the bottom surface position, a sliding rod is fixedly installed, on the bottom surface of the detection box near the center position, a mounting seat is movably installed, and on the inner surface of the detection box near the upper surface of the decibel meter, a limiting strip is fixedly installed". In the utility model, through the provided shock-absorbing seat and turning knob, the motor to be detected is placed on the shock-absorbing seat, the adjusting screw is rotated, so that the placing arc plate rotates around the second rotating shaft, so that it fits the lower surface of the motor, and the clamping seat is pulled downwards to make it contact with the upper surface of the motor, completing the clamping work of the device. This clamping method of clamping up and down and being able to adjust the contact area between the clamp and the motor is simple and efficient in operation and can be applied to motors of different sizes.

[0004] However, the above method still has the following defects: By placing the device to be tested at the fixture for clamping and fixing and using a decibel meter for noise detection, when the device to be tested contacts the fixture, the interaction between the two may induce unnecessary vibration and resonance phenomena. These additional factors will interfere with the true performance of the device's own noise, resulting in the detection data deviating from the actual value; In addition, the provided shock-absorbing seat, as a buffering measure, also weakens the noise, affecting the noise detection effect of the device to be tested, and further affecting the product qualification rate.
