NSRH Roots Blower Installation Tips That Prevent Noise, Vibration, and Early Failure

Installing an NSRH Roots blower is not just about putting it in place and switching it on. Many common problems such as loud noise, strong vibration, oil leaks, or unstable pressure are caused by poor installation, not by the blower itself. Based on proven industry practices and real installation experience, this guide walks you through the key points that help your NSRH Roots blower run smoothly from the very beginning.

1. Before Installation: Match the Blower to the Job

1.1 Confirm Model and Working Conditions

Before installation, make sure the NSRH Roots blower model fits your application. Check airflow, pressure, speed, and motor power. A blower that does not match the system will struggle, consume more energy, and wear out faster.

1.2 Inspect the Equipment

Carefully inspect the blower casing, rotors, bearings, gearbox, and accessories. Remove all inlet and outlet covers and ensure no dust, rust, or foreign objects are inside the blower.

2. Foundation and Alignment: The Base Matters More Than You Think

2.1 Strong and Rigid Foundation

The blower must be installed on a solid concrete foundation with enough strength and rigidity. Weak foundations amplify vibration and noise and can damage bearings over time.

2.2 Leveling and Alignment

Use proper tools to level the blower accurately. Poor leveling or misalignment leads to uneven rotor clearance, abnormal noise, and reduced service life.

3. Piping System: Reduce Stress and Resistance

3.1 Inlet and Outlet Piping

Keep the pipes short, straight, and smooth. Avoid sharp bends, sudden diameter changes, and unnecessary valves. High resistance increases pressure loss and raises blower temperature.

3.2 Flexible Joints and Safety Devices

Install flexible connectors to isolate pipe stress from the blower. Safety components like check valves, pressure relief valves, and silencers are essential to protect the blower and improve operating comfort.

4. Lubrication and Cooling: Don’t Skip the Basics

4.1 Correct Lubricating Oil

Fill the gearbox and bearings with the recommended oil type and quantity. Check oil level before startup and never run the blower dry.

4.2 Cooling System Check

Ensure cooling air paths or water cooling lines are clear and properly connected. Poor cooling is a common cause of high temperature and oil breakdown.

5. Electrical Connection and Rotation Check

5.1 Power and Wiring

Confirm voltage, frequency, and wiring match the motor nameplate. Proper grounding is critical for safety and stable operation.

5.2 Rotation Direction

Jog the motor briefly to check rotation direction. Reverse rotation can damage rotors and seals within seconds.

6. Trial Run: Start Slow and Observe

6.1 No-Load Startup

Start the blower without load if possible. Listen for abnormal sounds and check vibration levels.

6.2 Gradual Loading and Monitoring

Slowly apply load and monitor pressure, temperature, noise, and current. Stable readings mean the installation is done right.

Final Thought: Good Installation Saves Money

A properly installed NSRH Roots blower runs quieter, lasts longer, and costs less to maintain. Have you ever faced problems after installing a Roots blower? Share your experience, it may help others avoid the same mistake.
