3 reasons for the windscreen wiper arm makes abnormal noise The wiper blade is exposed to the outside of the car for a long time, and it is easily attacked by air or foreign objects, such as

2EFF BMW Code — Troubleshooting Fan Self-Diagnosis

The radiator fan''s failure to regulate temperature can have a cascading effect on overall engine efficiency and, most importantly, its health. Unusual Fan Noises. Listen for any abnormal sounds coming from the fan.

Sound science: Understanding and implementing generator

Cooling fan noise. Sound emanates from turbulent air as the cooling fan moves it across the engine and through the radiator. The amount of sound varies with the speed and volume of air

(PDF) Investigation of fan fault problems using vibration and noise

The basic assumption made in deriving this formula is that sound radiation from an axial flow fan in a free field is primarily due to the fluctuating pressure exerted on the

Abnormal Noise from The Fan Blades of Diesel

When a diesel generator set is in operation, as the fan blades are used for a long time, there may be a sudden "clattering" noise, especially as the engine speed increases, the noise also increases accordingly. This

Noises A Case Fan Makes When Going Bad

This can result in a grinding sound as the fan blades spin. 2. Misaligned Fan Blades: If the fan blades become misaligned or damaged, they can rub against the housing, causing a grinding noise. This can occur due to

11 Reasons Your AC Unit Is Making Loud Noise and

Damaged blower fan bearing or blade. Damaged AC compressor valve. Damaged condenser fan bearings. How to Fix It. Turn off the unit to prevent additional wear and tear. Then, carefully inspect the blower fan,

The 7 Common Causes Of An Excessively Noisy

Damaged Fan Blades. Another potential reason your generator makes so much noise is that the fan blades are damaged. The fan blades are responsible for moving air through the generator; if they are damaged, they

Why Is My Generator Making So Much Noise?

If the fan blades on your generator are imbalanced, they can create a lot of unnecessary noise. To solve this problem, try balancing the blades using a kit specifically designed for that purpose. If the problem persists, you

What is the reason for abnormal noise when the centrifugal fan is

The faster the speed, the wider or thicker the blade, the sharper the noise; the blade installation angle is too large, or the fan blade bending changes too much, resulting in eddy currents

Generator Making Noise(Revving, Funny, Clicking, Popping, Knocking)

Invest in attenuators. Attenuators will absorb the sound a generator produces, reducing the noise to acceptable levels. 5). Use Water. Rather than installing a muffler, attach one end of a hose

Generator Making Noise(Revving, Funny, Clicking,

Invest in attenuators. Attenuators will absorb the sound a generator produces, reducing the noise to acceptable levels. 5). Use Water. Rather than installing a muffler, attach one end of a hose to the exhaust. Run the other end to a

5 FAQs about [Abnormal sound from the fan blades of the Sylphy generator]

Why does a fan make a loud noise?

The noise made because of turbulence caused by high-speed air before and after the fan passage. The noise is more pronounced and broad-band in the mid and high frequency (250 Hz - 8000 Hz). The number of blades and the speed of rotation of the fan determines the dominant frequencies.

What causes alternator noise?

Alternator noise – This is caused by cooling air and brush friction and ranges from approximately 80 dB(A) to 90 dB(A) at one meter. Induction noise – This is caused by fluctuations in current in the alternator windings that give rise to mechanical noise that ranges from 80 dB(A) to 90 dB(A) at one meter.

Do reciprocating engine-powered generators make noise?

Like many types of rotating machinery, reciprocating engine-powered generator sets produce noise and vibration. Whether these generator sets run continuously in prime power applications or only occasionally in standby applications, their operating sound levels often must be reduced to comply with local, state or federal ordinances.

Where can I find sound performance data for generator sets?

Sound performance data for generator sets from Cummins Power Generation Inc. are available on the company’s design software CD (called “Power Suite”). Sound performance data is also available in the Power Suite Library on the company’s Web site:

How loud should a generator be?

Whether these generator sets run continuously in prime power applications or only occasionally in standby applications, their operating sound levels often must be reduced to comply with local, state or federal ordinances. In North America, maximum permitted overall noise levels range from 45 dB(A) to 72 dB(A), depending on location and zoning.
