Blower noise reduction
Blower noise includes aerodynamic noise, aerodynamic noise, mechanical noise, electromagnetic noise, and structural noise. The strongest of these are aerodynamic noise, blowers, followed by mechanical and electromagnetic noise. According to the size of the blower noise , site conditions, and noise control requirements, Tianjin Blower's optional noise control measures include: installing a muffler, installing a sound insulation cover, sound absorption, sound insulation, vibration reduction and vibration isolation.
1. The noise of the casing and the motor can be solved by installing a sound insulation cover. The price of the Tianjin blower is to perform sound absorption and sound insulation in the fan room.
2. Install a muffler outside the air inlet and outlet of the blower, with built-in muffler inserts, to reduce noise when passing through a specially constructed muffler. Blower manufacturers , mufflers are an effective measure to reduce the radiation of air intake and exhaust ports of air power equipment or pass noise along the pipe .
3. The fan is suspended by a damping spring hanger shock absorber.
Blower noise reduction can be designed in accordance with factors such as the sound source object, noise characteristics, noise reduction requirements, process conditions, and installation location to ensure a good noise reduction effect.
Common sense of high pressure blower:
A high-pressure blower is a machine used to compress and transport gas. From an energy point of view, it is a machine that converts the mechanical energy of a prime mover into gas energy. Classification and use of blowers:
1? Classified by principle of action:
a. Turbine Fan — A fan that compresses and conveys gas by rotating blades.
b. Volumetric fans—compress and transport gas machinery by changing the volume of the gas.
2? Classified by the direction of airflow movement:
a? Centrifugal fan—After the airflow enters the fan impeller in the axial direction, it is compressed under the action of centrifugal force and flows mainly in the radial direction.
b? Axial-flow fan—The air flow enters the rotating blade channel in the axial direction. Because the blade interacts with the gas, the gas is compressed and flows approximately along the axis of the cylindrical surface after being compressed.
c? Mixed-flow fan — The gas enters the rotating blade at a certain angle with the main axis, and flows approximately along the cone surface.
d? Cross-flow fan — the gas traverses the rotating blades, and is increased by the pressure of the blades.
3. Classification by production pressure (calculated by fixed pressure)
1? Ventilator-exhaust pressure below 31270Pa
2? Blower — exhaust pressure between 35270Pa ~ 343000Pa
3? Compressor-exhaust pressure above 343000Pa
4? The corresponding classification of high and low pressure fans is as follows (under standard conditions)
a Low-pressure centrifugal fan: full pressure P ≤ 1000Pa
b. Medium pressure centrifugal fan: full pressure P = 1000 ~ 5000Pa
c. High pressure centrifugal fan: full pressure P = 5000 ~ 30000Pa
d. Axial fan for low pressure heat exchanger: full pressure P ≤ 500Pa
e. Axial fan for high pressure heat exchanger: full pressure P = 500 ~ 5000Pa
Fourth, the full name and model of the fan:
1. The general name of the general ventilator:
2. Model and variety composition:
Five, the concept of the main technical parameters of the fan
1. Pressure: The pressure of the ventilator refers to the pressure increase (relative to the atmospheric pressure), that is, the increase in the pressure of the gas in the fan or the difference between the pressure of the gas at the fan inlet. It has static pressure, dynamic pressure and full pressure. The total pressure is equal to the total
Often expressed in P. Its unit is often expressed in Pa. Kpa.
2. Flow rate: The volume of gas that passes through the fan in unit time, also known as air volume.
It is usually expressed by Q. Its unit is usually m 3 / h. M3 / min.
3. Rotating speed: the rotating speed of the fan rotor.
It is usually expressed in n. Its unit is r / min (r is the speed and min is the minute).
4. Power: the power required to drive the fan.
It is often expressed as N. Its unit is Kw.
