How to disassemble and assemble Roots pump?

-

 Roots pumps, or mechanical booster pumps, require careful handling during disassembly and assembly to avoid damage and ensure their efficient operation. Following the correct procedures and taking necessary precautions can significantly prolong the pump's lifespan and maintain its performance.Let's learn how to disassemble and assemble Roots pump

Disassembly Procedure for Roots Pumps

To disassemble a Roots pump, follow these steps in sequence:

  1. Drain Lubricating Oil and Cooling Water: Before beginning the disassembly process, ensure that all lubricating oil and cooling water are fully drained from the pump.

  2. Remove Coupling and Motor: Detach the coupling and motor from the pump. This step requires careful handling to prevent damage to the coupling and motor components.

  3. Dismantle Bypass Piping and Bypass Valve: Carefully remove the bypass piping and bypass valve from the pump to allow access to internal components.

  4. Remove Bearings: Extract the bearings from the pump to facilitate further disassembly of internal parts.

  5. Disassemble Front and Rear End Covers and Sealing Devices: Remove the front and rear end covers along with any sealing devices to expose the internal structure of the pump.

  6. Remove Drive Gears: Detach the drive gears from the pump, taking care not to damage any gear teeth or related components.

  7. Remove Rotors: Carefully remove the rotors from the pump, ensuring that no damage is inflicted on the rotors or the pump body.

Precautions During Disassembly and Assembly

While disassembling and assembling the Roots pump, keep the following precautions in mind to ensure the integrity and performance of the pump:

  1. Ensure Proper Leveling of the Base: When installing the base, it is crucial to adjust it accurately to maintain a level position. Incorrect leveling can affect the clearance between the rotors and the pump body ends, leading to operational issues.

  2. Avoid Using a Hammer on Components: Do not use a hammer to strike or dislodge parts during disassembly or assembly. Use appropriate tools to avoid damaging the precision components of the pump.

  3. Protect Sealing Surfaces: Handle the sealing surfaces with care to avoid scratches or dents, which can compromise the sealing integrity and lead to leaks.

  4. Apply RTV Silicone Sealant Properly: When using RTV silicone sealant for flat sealing, apply it evenly. Avoid applying it too thinly or too thickly to ensure a proper seal.

  5. Adjust Rotor Clearance Accurately: After installing the rotors, carefully adjust the clearance according to specified values. If the clearance exceeds the recommended limits, remove and repair the rotors as necessary. After repair, conduct a dynamic balance test to ensure the rotors are balanced before reassembly.

By following these steps and precautions, you can safely disassemble and reassemble Roots pumps, ensuring their optimal performance and longevity.
