Even under the best maintenance program, fans and blowers inevitably will need to be replaced or repaired. Plant engineers also have the option of rebuilding, which is an extensive form [...]

When a fan or blower breaks down or becomes worn, customers have two choices. They can replace it or they can have it repaired. In the past, replacement was the [...]

By Thomas J. Kuli and Tim Rape, Robinson Industries Inc. Repairing or rebuilding existing process fans can often lead to better efficiencies and cost savings Traditionally, as fans and blowers [...]

Imbalance is a problem with all industrial fans including those used in the aggregate industry. Imbalance is a potentially dangerous condition and can result in breakdowns and costly plant shutdowns. [...]

When a fan or blower breaks down or becomes worn, metalproducers have two choices. They can replace it or they can have it repaired. The trend is to opt for [...]

Fans play a key role in most manufacturing processes by recirculating air, ventilating hazardous gases, and cooling machinery. One problem that can develop in all of these applications is imbalance. [...]

The benefits of fan repair versus fan replacement in plants are discussed. Analyzing fan performance data allows repair specialists to select the most appropriate metals or exotic alloys and make adjustments to enhance equipment life. It is believed that cost savings from repairing or rebuilding can range from 20% to 80%.

Imbalance in industrial fans for pulp and paper processing can lead to failures, breakdowns, operations shutdowns, and vibration. Regular inspection and maintenance, which offer potential for preventing damage to other machines, can be done with the use of proximity probes. The causes of industrial fan imbalance are also presented.

In wet scrubber applications used to control industrial air emissions, the main challenge is often corrosion. Dirty, wet air is forced through a tightly confined area, making intimate contact with [...]

Provides information on vibration and imbalance in industrial fans. Common plant situations that can lead to imbalance includes build up of particulate matter on fan blades and differential temperatures between the top and bottom of the fan housing; Importance of clarifying the difference between imbalance and vibration; Components of a fan rotor; Suggestion on monitoring the health of a fan.

The article discusses the cost saving effectiveness of fans used in mines and mining. Customers are choosing the repair option over replacement because its cost savings can range from 20 to 80 percent. Regular inspections and documentation of wear is a way to save money on repair costs. Rotor balancing is a requirement in fan field service work.

Discusses cost-effective solutions for wet rubber applications for controlling industrial air emissions. Benefits of using a fiberglass-reinforced plastic fan housing; Material for fan housings in wet scrubber applications; Examples of possible combinations of rotor and housing materials that can be used to minimize or prevent corrosion.
