4 Common Signs That Your Industrial Blower Needs Repairs

By In Blog On November 2, 2018

Blowers play an important role in the industrial setting. These pieces of equipment deliver airflow for processes such as conveying, cooling, and exhausting.

To perform its functions, an industrial blower has features such as louvers, dampers, variable-speed motors, diffusers, flanges, ports, and blades. With time, these parts can succumb to wear and tear and will affect the efficiency of the blower. Early repairs can prevent the need to replace your industrial blower prematurely.

Here are common industrial blower problems that may necessitate repairs.

1. Inadequate Airflow

The primary purpose of a blower is to facilitate airflow through ducts, chassis, or any other outlets in a building. Several issues could lead to inadequate airflow or a complete lack of airflow. Common culprits are broken fan belts or faulty couplings. Fixing faulty belts or coupling can restore normal airflow.

A malfunctioned check valve can also affect the airflow. In particular, the check valve ensures that air flows in one direction for optimal cooling or ventilation. A faulty check valve will, therefore, diminish the blower’s capacity to distribute air through designated outlets.

A leaky pipe in the ductwork could impede the proper flow of air. Loose gaskets can also contribute to such leaks. Consider replacing old gaskets and checking for any leakages in the ductwork.

2. Extreme Heat

Just like most industrial machines, extreme temperatures can diminish the efficiency and service life of a blower. A blower that is too hot to the touch could be due to mechanical issues with the equipment. Possible causes of such overheating include dirty air filters, excessive oil in the gearbox, clogged air inlets, or a faulty impeller just to mention a few.

Dirty air filters can cause the blower to work harder to facilitate adequate airflow, and this could lead to overheating. Avoid this by scheduling regular maintenance and replacement of air filters.

Check for clogs that could be blocking valves or inlets. Obstructions can prevent the normal flow of air, therefore causing heat to accumulate within the blower.

Excessive oil, low levels of oil, and old oil can all cause the blower to exert more mechanical pressure than is necessary. Drain excess oil from the gear oil, and be sure to change the oil based on the manufacturer’s recommendations.

3. Insufficient Lubrication

The various components of a blower require enough lubrication to safeguard against corrosion and related mechanical failures. Check for signs such as rust, noisy operations, and oil on the floor or underneath the blower.

Find a certified professional to fix a leaking blower immediately to avoid a complete breakdown of the equipment. You may need to disassemble the blower to replace corroded components such as gaskets, seals, and bearings.

4. Excessive Vibration

Excessive vibration of the fan or the entire blower system can accelerate wear and tear of critical components. Vibrations could be due to loose belts, excessive speed, misaligned shafts, a shaky base, or faulty bolts.

Inadequate tension in the belt drive can cause the belts to fly around, resulting in major vibrations in the blower. Loose belts could also cause the fan to operate below the standard speed. This can force the blower to work harder, resulting in additional problems such as overheating.

Fasteners that come lose can cause the base to separate from the rest of the blower, resulting in a noisy vibrating sound. Check that the base is firmly fixed to the blower’s body. In addition, check for any loose bolts elsewhere in the blower, and replace aged fasteners to keep the components in the blower from moving and rattling.

While you can troubleshoot some common problems, you should leave major repair and maintenance of industrial blowers to a certified technician.
