Master the Twin Lobe Roots Blower Installation Guide with easy steps for air-cooled and water-cooled systems, plus maintenance tips and FAQs

Twin lobe Roots blower is a special type of machine used in various industrial operations to move air or gas from one place to another, increase pressure or create a vacuum. This blower plays a vital role in many sectors like water purification, cement production, fish farming, and pneumatic transportation. In this blog post, we will explain the installation of twin lobe Roots blower, the difference between air cooled and water cooled blowers, and their installation process in a very simple way. Let’s get started!

What is Twin Lobe Roots Blower?

Twin Lobe Roots Blower Installation Guide

Twin lobe Roots blower is a positive displacement machine, which has two lobes (rotors) that rotate in opposite direction to each other. These lobes draw air in from one side and expel it with pressure from the other side. Its specialty is that it provides oil-free air, making it ideal for water treatment, food processing, and chemical industries. This blower is available in two types: air cooled and water cooled. Both have their own advantages and uses, which we will understand further.

Air Cooled Twin Lobe Roots Blower

In air cooled blowers, the machine is cooled using air. It is suitable for applications where the pressure requirement is low, such as less than 10 psi (7000 mm WG). This type of blower is easy to install and requires less maintenance. It is lightweight and ideal for small-medium scale operations.

Features of Air Cooled Blower:

  • Low cost: It is cheaper than water cooled.
  • Easy maintenance: It does not require a water system, which makes maintenance easier.
  • Uses: Useful in water treatment plants, fish farming, and small scale pneumatic transport.

Water Cooled Twin Lobe Roots Blower

Water cooled blowers are designed for applications where high pressure is required, such as more than 10 psi. This blower has water jackets that reduce the heat generated in the machine. This blower is suitable for heavy-duty tasks and is built to last for a long time.

Features of Water Cooled Blower:

  • High Pressure Capacity: It is suitable for high-pressure tasks.
  • Long Life: Bearing and seal life increases due to water cooling.
  • Uses: Useful in cement industry, chemical plants, and paper mills.

Installation Process of Twin Lobe Roots Blower

Installation of twin lobe roots blower is an important process, which needs to be done correctly so that the machine works smoothly for a long time. Below we have explained the installation steps in simple Hindi:

1. Selecting the Location

Select a flat, strong, and vibration-free surface to install the blower. Make sure the location has good ventilation, especially for air-cooled blowers. For water-cooled blowers, there should be water supply and drainage facilities. The location should be such that servicing and maintenance of the machine can be done easily.

2. Preparation of the base

Make a strong concrete base to install the blower. Use a leveling tool to level the base. The blower is firmly attached to the base with bolts so that there is no vibration during operation.

3. Installation of the blower

  • Inspection of the equipment: Check all parts (lobes, gears, bearings) before installing the blower. Make sure no part is damaged.
  • Placement: Place the blower on the base and secure it with bolts.
  • Pipeline connection: Connect the inlet and outlet pipes to the blower. Make sure there are no leaks in the pipes.
  • Air filter and silencer: Install an air filter and silencer in the air-cooled blower to reduce dust and noise.

4. Additional Steps for Water Cooled Blower

  • Water Supply: Connect the water inlet and outlet pipes to the water cooled blower. The water supply must be clean and cool.
  • Water Flow Check: Ensure that the water flows in the right direction and there are no blockages.
  • Cooling System: Check the water temperature and pressure regularly so that the blower does not overheat.

5. Electrical Connections

Use the correct wiring to connect the blower to the motor. The capacity of the motor should be as per the blower requirement. Get the electrical connections done by an expert so that there is no risk.

6. Testing and Startup

  • Double check all connections before turning on the blower.
  • Start the machine at low speed and check for any unusual sound or vibration.
  • Measure the air flow and pressure to ensure that the blower is working correctly.

Maintenance Tips

  • Air Filter: Clean or replace the air filter regularly.
  • Gears and Bearings: Periodically add lubricant to the gears and bearings.
  • Water check: Check the water quality and flow in the water cooled blower.
  • Noise and vibration: If there is abnormal noise or vibration in the machine, check immediately.

Conclusion

The twin lobe Roots blower is a powerful and reliable machine that plays a vital role in many industries. Whether you choose an air-cooled blower or a water-cooled one, it is important to do the installation and maintenance of both correctly. The information provided in this article will help you understand and implement the installation of the blower easily.
