When a larger volume of air flow is required at higher pressure, the blower is used in industry.The fan with a higher pressure ratio (output pressure/input pressure) can be called a blower as long as a pressure of up to 1 is generated.20 kg/cm2.Like the fan system, the blower is widely used in industrial processes, under higher pressure, such as the conveying material in the dust collector system, the burning air of the burner, requires constant air/gas flow, dry and cool, total ventilation and circulation of air, etc.
Higher efficiency blowers are also used in industrial vacuum systems that require suction or negative pressure.The industrial blower is roughly divided into centrifugal blower and positive blower.Replacement blower.Centrifugal blowers have several advantages over other blowers because they have a wide range of work and are fast.
Centrifugal Blower is a constant capacity device that is designed to rotate a high-speed impeller or blade at a speed of about 15,000 rpm.The airflow speed entering the blower is increased by the impeller or blade, in the impeller or blade, the airflow obtains kinetic energy and accelerates at a higher pressure through the radial outlet.Like the centrifugal fan system, they have different drive mechanisms such as belt drive, variable drive, and direct drive.
To adjust the air flow rate, the centrifugal blower is equipped with shock absorbers and blinds, pipes and other similar airflow resistance components.The centrifugal blower can be single or multiple.The stage unit can have different blade directions such as radial, forward and backward bending.
Typically, a first-stage centrifugal blower is used when uniform air flow is required, whereas a multi-stage centrifugal blowerWhen it is necessary to change the air flow at a fixed pressure, the stage blower is useful.According to their ability to generate pressure during operation, they are basically divided into three types.They are centrifugal blowers for low, medium and high pressure.
Since the centrifugal blower can operate at a high impeller speed, it can be used in industrial applications with lowto-Static pressure of radial media.The various blade configurations of centrifugal blowers enable them to operate in a wider environment and under different airflow/pressure conditions.Compared to other types of blowers at the same rpm, they can generate more pressure at a given rpm.
Since their horsepower capacity is higher than others, there is less overload and possible damage to the motor.Since there are multiple sizes and blade arrangements for centrifugal blowers, they may be a better choice for places where space is preferred.Centrifugal blowers are widely used in industrial applications.
in industrial applications, it is necessary to continuously flow larger volumes of air, such as ventilation, combustion, conveying materials, cooling and heating systems, dust control, air conveying systems, industrial vacuum applications and other industrial processes.The centrifugal blower varies depending on its airflow capacity, blower type, blower size and maximum working pressure.They can be customized and installed on demand to meet the needs of a wide range of industrial applications.
