Method for testing the sound insulation and wind resistance of automatic doors

In addition to the beautiful appearance and fashionable atmosphere of the automatic door, there are many special functions that everyone does not understand. Sound insulation and wind resistance is an important function of automatic doors, so when we buy automatic doors, in addition to price and quality, we must also consider the sound insulation and wind resistance of automatic doors. It is also the key to testing the quality of an automatic door. Sexual factors, how to test the sound insulation and wind resistance of automatic doors?

 

The sound insulation and wind resistance of automatic doors is an important indicator for evaluating the quality of the door, and it is also an important aspect that consumers pay most attention to when purchasing automatic doors. However, since there is no uniform standard for the sound insulation and wind resistance of automatic doors, users must test them to ensure the performance of the door. Regarding the test method for the sound insulation and wind resistance of automatic doors, the following measures can be taken.

The test of the sound insulation and wind resistance performance of automatic doors can be mainly carried out in two steps. First, test the sound insulation and running noise of the door. The test method is to use a sound level meter for the running door at a distance of 1m from the center of the door and a height of 1.5m under the condition that the door is in normal working state and the ambient noise is not greater than 45dB. Take the average of five measurements. For the test of the wind resistance performance of automatic doors, similarly, when the door is working normally, the door leaf can be placed in the open or closed state, and air is supplied along the vertical direction of the door at a wind speed of 10m/s, and the state and action of the door can be checked. Is there any exception. When the automatic revolving door and semi-automatic revolving door are cut off from the power supply, fix the dynamometer in the middle of the moving fan to slowly apply a horizontal force parallel to the level of the door leaf, open or close the door leaf, and record the maximum force on the dynamometer. value, test three times in a row, and take the average value. In this way, the user can make an approximate evaluation of the performance indicators of the door body’s sound insulation and wind resistance, and can also have a simple judgment on the quality of the door body.

I believe you have a simple understanding of the basic methods of testing the sound insulation and wind resistance of automatic doors. However, in order to ensure the superior performance of the door, the automatic door manufacturer recommends that users choose a well-known one that has passed the international standard when purchasing. , State-certified automatic door manufacturers, such a company has always maintained the door body performance of automatic doors at a high-quality level, and has a good reputation in the industry. It is currently a well-known automatic door manufacturer in China.

The above is the method of testing the sound insulation performance of automatic doors. When purchasing automatic doors, you can test according to the above measures, so as to ensure the quality of automatic doors and ensure the normal use of automatic doors.
