May 27,2021

Share:

In some respects,best cordless vacuum have indeed brought great convenience to our lives, such as cleaning and hygiene; but in other respects, handheld vacuum has also brought some troubles to our daily lives, such as noise problem. 

The noise of the vacuum cleaner is always very loud, if someone is resting, it will definitely be affected. So is there any way to reduce the noise of the best vacuum?

  • 1. The Source Of Noise From Vacuum Cleaners

    Generally, household vacuum cleaners draw small particles into a dust bag or dust cup by vacuum, that is, negative pressure. The vacuum is generated by amotor driven by a vortex fan, and the speed can be as high as 40,000 revolutions per minute, which is not achieved by ordinary motors. Therefore, the higher the speed, the greater the suction, and the greater the noise, which is almost proportional to this aspect. Echoes in the room will also objectively increase the noise of the vacuum cleaner, which is because people feel that the noise is very loud.

2. How To Reduce The Noise Of The Vacuum Cleaner


1. Opening The Window


In the course of use, opening the home windows can effectively reduce the noise echo, and feel that the noise will be reduced.

2. Adjusting the power

Adjusting the size of the power can also reduce the noise. In general household cleaning, it can basically be done with the smallest power. At this power, the noise of the portable vacuum is much reduced. And it saves energy effectively


3. Isolation technology


Noise reduction can effectively reduce a certain amount of noise through the degree of machine sealing and the noise reduction technology of a large manufacturer. For example, the various isolation technologies of the YijieSilent King series effectively reduce the noise.


4. Motor vibration isolation


The solution to the interference vibration is to install a shock absorber on the vacuum motor. When the natural frequency of the shock absorber is greater than the interference vibration frequency of the vacuum motor, the shock absorber cannot achieve the effect of vibration isolation. 


When the interference vibration frequency of the vacuum motor is equal, the vibration absorber will not only not have the effect of vibration isolation, but also amplify the vibration due to the super position of sound waves. Only when the natural frequency of the vibration absorber is less than 1.4 2 times the interference vibration frequency of the vacuum motor.  The vibrator has the effect of vibration isolation.



What To Do If The Vacuum Cleaner Is Noisy

1. Adjusting The Power Of The Vacuum Cleaner Can Reduce Noise


In general household cleaning, the minimum power is basically enough. With low power, the noise is naturally small, and it is effective in energy saving.


2. In The Process Of Using The Vacuum Cleaner


opening the window can effectively reduce the noise echo, which will have acertain effect.


3. It is the noise generated by the vibration of the motor


The best way is to hit the vacuum motor with a shock absorber. When the natural frequency of the shock absorber is greater than the interference vibration frequency of the vacuum motor, the shock absorber will not be able to isolate vibration.


Effectively, when the natural frequency of the shock absorber is equal to the interference vibration frequency of the vacuum motor, the shock absorber will not only not have the effect of vibration isolation, but will also amplify the vibration due to the super position of sound waves. 


Only when the natural frequency of the shock absorber is less than the vacuum. The shock absorber has the effect of vibration isolation only when the interference vibration frequency of the motor is 1.42 times.



How To Repair A Broken Vacuum Cleaner


1. The Noise Of The Vacuum Cleaner Becomes Louder


Generally, hand vacuum cleaner are a little noisy when they are in use. This depends on the size of the noise. If the sound of the vacuum cleaner is not loud but it suddenly increases in one day, the cheap vacuum cleaner is broken. There are two reasons: one is that the fixing element of the vacuum cleaner is loose, and at this time, it is only necessary to reinforce the element. The second is that the motor fan has fallen off, and the fan hits the casing when it is running.You only need to adjust the motor fan.


2. The Vacuum Cleaner Motor Does Not Rotate


The vacuum cleaner motor does not rotate is a common fault. It may be that the internal brushes of the motor are burned out or worn too badly before, or the circuit of the vacuum cleaner is incorrect, the contact between the vacuum cleaner and the socket is poor, etc. These must be checked and confirmed one by one. If there is a problem with the motor, if it is confirmed that the brush cannot continue to work, replace it with a new one. If the contact is not good,reconnect the power to the vacuum cleaner.


3. The Suction Power Of The Vacuum Cleaner Becomes Smaller


If the suction power of the vacuum cleaner becomes weak, it is likely that the internal fuse has burned out. In this case, just replace it with a new fuse and restart it. The power cord of the vacuum cleaner is in poor contact, causing the internal power of the machine to be in sufficient, and the suction power will be reduced. You need to change a plug to turn on the power. If the motor of the vacuum cleaner is broken, you have to replace it with a new one.


4. The motor of the vacuum cleaner rotates without dust

When you turn on the vacuum cleaner, you can hear the sound of the motor rotating, but it just doesn't vacuum. It may be that the dust bag inside the vacuum cleaner is full, or the hose may be blocked. You need to clean up the garbage in the dust bag and then unblock the hose. Another possibility is that the connection between the vacuum cleaner hose and the brush head is loose, you only need to reconnect them.
