Reasons for the large noise of sanitation sprinklers and their solutions

Sanitation sprinkler occupies an extremely important position in our daily life and has a wide range of uses. However, the wider the application is, the more obvious the disadvantages are exposed. For example, residents of many cities are now discussing the issue of noise from sanitation sprinklers, and many local media have also reported it repeatedly. Well, since someone has raised a problem, it has to be solved. Let's analyze the causes of the loud noise of the sanitation sprinkler and the solution to reduce the noise.

Sanitation sprinkler noise causes

The first reason: Because sanitation sprinklers belong to special vehicles, large-scale automobile factories do not bother with this market segment, so they are generally manufactured by small and medium-sized vehicle manufacturers. However, the small plant's development of technical capacity is relatively poor, simply did not expect to reduce noise, coupled with the procurement department is not sensitive to noise, sanitation sprinkler vehicle factory there will be no power to reduce noise.

The second reason is that the noise generated by the engine is mainly divided into combustion noise, mechanical noise, and intake and exhaust noise. Combustion noise refers to the noise generated when the cylinders burn fuel and the pressure radiates outward through the pistons, connecting rods, crankshafts, and cylinders. Therefore, the sound is relatively large.

Sanitation sprinkler noise reduction method

1. Shock Absorption: Since the materials used to make the sprinkler are metal and plastic plates, it is inevitable that resonance will occur during driving, which will cause a lot of low-frequency noise. Although the original sprinkler will also handle some of the vibration sources, it is not enough. Therefore, it is necessary to install shock-absorbing materials in both high-end cars and middle- and low-end cars.

2. Sound Absorption: When the sprinkler runs at high speed, the body itself will generate resonance noise, so it is necessary to install high-efficiency sound-absorbing cotton for noise reduction and noise reduction.

3. Sound insulation: Since the metal and plastic plate materials of medium and low-grade vehicles are relatively thin, they can not effectively prevent the introduction of external noise, so it is possible to install noise-blocking thick plates to block the noise.

From the above analysis, it can be seen that solving these problems is not a difficult task but only a matter of time.
