Introduction: The blower is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base (also serving as oil tank), and drip nozzle. The blower relies on the eccentric operation of the rotor biased inside the cylinder, and changes the volume between the blades in the rotor slot to suck in, compress, and discharge air.
During operation, the pressure difference of the blower is used to automatically send lubrication to the drip nozzle and drip it into the cylinder to reduce friction and noise, while also keeping the gas inside the cylinder from flowing back. This type of blower is also known as a slide type blower.

The conveying medium of the blower is mainly clean air, clean coal gas, sulfur dioxide, and other inert gases. It can also produce and transport other flammable, explosive, corrosive, toxic, and special gases as needed. Therefore, it can be widely applied to various industrial sectors such as metallurgy, chemical industry, fertilizer, petrochemicals, food, building materials, petroleum, mining, textiles, gas stations, pneumatic conveying, sewage treatment, etc.
blowerThe use of blowers and each component are intricately linked. If we ignore one of them, the effectiveness of blowers in use will be disrupted. Faced with various problems with blowers, we may feel that there are so many issues with their use, so we should try not to choose them. This is completely wrong. Currently, there are few other devices that can replace the effectiveness of blowers in terms of ventilation. Therefore, equipping a blower for a place and environment is the best choice. However, what should we do to address the noise problem of blowers?
The solution is actually very simple, the key is the reason. If we don't even know the main cause of the noise generated by the blower, it will be difficult to solve practical problems. When it comes to noise, one reason we all know is the blade problem of the blower. Many times, the noise generated by the blower is often caused by the rotation of the blades, eddies, turbulence, and other phenomena.
When the blades rotate, they will generate friction or impact with the air. When the blades rotate, they will generate friction or impact with the air. The faster the speed, the higher the frequency of the air, and the sharper the noise. The faster the speed, the higher the frequency of the connecting air, and the sharper the noise. As the width or thickness of the leaves increases, this phenomenon becomes even more pronounced.
During the operation of the blower, vortices are generated on the back of its moving wings, which not only reduce the efficiency of the fan but also generate a large amount of noise. To reduce this phenomenon, the installation angle of the blades should not be too large, and the bending of the fan blades should be smooth and not suddenly change too much.
When the air is flowing, if it encounters sharp obstacles during use, it is easy to cause turbulence. Although this turbulent flow is different from eddy currents, it can also produce noise or high-frequency whistling sounds, which can cause efficiency loss for the blower.
From these points, it can be seen that in order to solve the noise problem of the fan to a certain extent, it is necessary to solve all the related problems of the blades, which is the key to solving the problem.
