Benefits and Applications of Centrifugal Blowers

Of all the different available fans, centrifugal fans, which are also known as centrifugal blowers, are the most common. While many people have heard the name, some still have no real understanding of what the benefits or applications are for this type of blower.

Centrifugal

Centrifugal, which is also known as a radial fan or blower, is a type of high-pressure blower. That means that high-speed blades provide velocity to air and other gasses. In addition to different blade orientations, which include straight, forward curved, and backward curved, these blowers are available in different voltages and speeds. Generally speaking, this high-pressure compressor blower is operated by an electric motor, although some do operate on drive motors.

Because of the volume and pressure of airflow, centrifugal blowers’ primary use is in air conditioning systems. However, these blowers can also be used to control dust, among other things. Based on the unique design of this high-pressure blower, which is often referred to as a hamster wheel, it is the preferred method for air circulation and cooling in office buildings, warehouses, plants, and other large spaces.

Axial

Some people refer to axial fans as blowers. In this case, blades that rotate around an axis work by drawing air in parallel to that axis, followed by forcing air out in the same direction. Although these blowers produce a high rate of airflow, the air is at low pressure. Unlike centrifugal blowers that can keep huge spaces cool, axial blowers are designed for cooling specific small spots or components within machineries like computers and photocopy machines.

Cross Flow

These blowers are commonly used by the electronics and HVAC industries, producing an even laminar airflow that, similar to axial blowers, keeps components from overheating. Whether mounted vertically or horizontally, these blowers are designed to deliver a two-dimensional flow. These blowers work especially well in areas with limited space.

Conclusion

As you can see, there are distinct differences between the three unique types of blowers. The benefit of centrifugal blowers is that they produce high-pressure and large volume airflow that keeps big spaces cool. In comparison, both axial and cross flow blowers are designed to keep various components from overheating.

What are FRP Fans?

FRP is the acronym for “Fiberglass Reinforced Plastic” so in the case of FRP fans, these units are designed for corrosive air movement applications. Depending on the model, the construction might include a backward curved wheel and have a controlled construction of lamination. With this, the fan would comply with current industry specifications. Typically to create a spark-resistant product, more layers of graphite impregnation and corrosion resistant cloth are added.

Markets for FRP Fans

There are different markets that use FRP fans, one being semiconductor manufacturing. For this industry, different corrosive and toxic materials are used during fabrication. In addition, prior to chips being assembled, different acids are used to clean the metals and throughout various stages of manufacturing, corrosive gases and acids are needed, the most common being phosphoric acid, ammonia, hydrofluoric acid, and hydrochloric acid.

For semiconductor manufacturing and most other industries, to be efficient and achieve success, it is vital that all systems run continually. However in doing so, workers could be at risk. In this situation, the facility where manufacturing occurs must have proper ventilation. Without proper venting, workers are exposed to acids and chemicals that could pose a significant health risk.

The great thing about FRP fans is that they offer the level of ventilation needed for semiconductor manufacturing and other industries, as well as applications. In addition, these fans have a solid reputation for providing years of service without fail and with very little maintenance needed. Because of this, people can work in a safe environment and there is little operation downtime. For more detail click here...

A Review of Variable Frequency Drives

Variable frequency drives (VFD), which are also known as AC drives, frequency drives, inverters, speed drives, and micro-drives, are motor controllers capable of driving electric motors. The way this is accomplished is that the frequencies and voltages going to electric motors are varied.

Brief Introduction to Variable Frequency Drives

This type of adjustable speed drive is used primarily in electro-mechanical drive systems as a means of controlling torque but also AC motor speed by varying input voltage and frequency of the motor. There are several applications that use these drives to include smaller appliances to massive mine mill compressors.

Today, roughly 25% of electrical energy in the world is consumed by electric motors within various industrial applications. Using a variable frequency drive in centrifugal load service, motors save energy. Although these drives are extremely popular within North America, they hold a very small market in other parts of the world. The bottom line, installation of variable frequency drives could significantly improve energy efficiency.

Throughout the past four years, the cost and size of variable frequency drives has been dramatically reduced thanks to power electronics technology. In addition, overall performance has been improved upon through advances made in semiconductor switching devices, control and simulation techniques, control software and hardware, and different drive topologies.

Understanding the Basics and Benefits of Variable Frequency Drives (VFD)

Variable Frequency Drives (VFD) are actually a motor controller responsible for driving an electric motor. This is accomplished by varying both the voltage and frequency applied. Because the frequency has a direct link to the speed at which the motor operates, also referred to as RPMs, the faster the frequency, the faster the RPMs.

In the event that the full speed of the motor is not required, the Variable Frequency Drive works by reducing voltage and frequency so that the speed requirements of the motor’s load are met. There are a number of benefits that go hand in hand with using this type of motor controller.

• Energy Consumption and Costs – A VFD helps reduce energy consumption and cost. As mentioned, if the full speed is not required for a certain application, energy consumption is less and energy costs decrease. Today, over 65% of all power consumption in industry comes from electric motor-type systems. By optimizing these with a VFD or even upgrading an existing VFD, energy consumption would be cut by up to 70%. Obviously, when less energy is used, the cost goes down.
  
• Improved Production – Variable Frequency Drives also improve the quality of the finished product while reducing operating costs. Especially in a world where the end-user demands perfection, having the opportunity to produce a much higher-quality product for less money is extremely beneficial for all parties.
  
• Tax Incentives and Rebates – It is quite common to see tax incentives coming from the government and rebates from utility companies for manufacturers who follow more energy-efficient practices. With the installation of a VFD, people can take advantage of these perks, which bolsters the return on investment. Original Source...

Benefits of Variable Frequency Drives

Also known as AC drives, variable frequency drives (VFD) are essentially controllers capable of driving electric motors, something accomplished by varying the voltage and frequency that goes into an electric motor.

AC Motor of Variable Frequency Drives

A variable frequency drive system uses an AC electric motor. Typically, this is a three-phase induction motor although a single-phase motor is also used on occasion. The benefit of a three-phase induction motor is that it works for most purposes and typically, it is the more cost-efficient solution. Keep in mind that when induction motors experience increased voltage stresses supplied by variable frequency drives, there has to be a design in place for definite-purpose inverter-fed duty.

Benefit of Energy Saving

A number of different load applications for a fixed speed motor supplied directly from AC line power save energy when operated with a variable frequency drive and at variable speeds.Original Source...

What Are the Various Types of Humidifiers?

Many types of humidifiers are available, each with a unique design and benefits. Regardless of the type of humidifier, it is used to create a higher level of moisture in a room. For people living with asthma, allergies, sinus infections, dry skin, and even symptoms that go hand in hand with the common cold due to a lack of moisture, humidifiers create a more comfortable and healthier environment.

Because moisture levels are carefully regulated by humidifiers, the air quality is cleaner and healthier. Ultimately, a humidifier reduces the concentration of bacteria, dust, and a host of other irritants. The biggest challenge comes from choosing the right product since there are multiple makes and models.

Overall, humidifiers are classified as warm mist or cool mist. Of the two, humidifiers that produce a cool mist are considered the safer option. The reason is that humidifiers that create a warm mist pose a burn risk, especially in a home with smaller children.

Warm mist humidifiers also require more electricity; therefore, they are more expensive to operate. The only real downside to cool mist humidifiers is that they require more maintenance, such as daily cleaning with soap and water and annual filter changes.

Differences Between Axial and Centrifugal Fans

Although there are some similarities between centrifugal fans and axial fans, there are also distinct differences. Regardless, both types of fans are used for industrial applications.

Centrifugal Fans

Centrifugal fans, also referred to as blowers and squirrel cage fans because they resemble a hamster wheel, were invented in 1832 by Lt. Gen. Alexander Sablukov, a military engineer with the Empire Imperial Russian Army. This type of fan is capable of moving air, as well as other gasses. The speed of the airstream increases thanks to rotating impellers, which are a series of blades.

The various types include forward curved, backward inclined, radial, airfoil, radial tip, and inline. Two specific characteristics of the centrifugal fan are high pressure and low flow rate, with flow perpendicular to the blower axis. Fans designed with paddle impellers are ideal whenever debris passes through the system, thereby preventing clogs. For fans with blades that curve backward, the volume of air produced is less than with axial fans while the amount of pressure generated is more significant.
