At IJB Engineering, we pride ourselves on our ability to tackle complex engineering projects with precision and expertise. Our recent project involving the installation of the Vexo X Pot in Plant Room P exemplifies our commitment to delivering high-quality solutions while addressing unforeseen challenges effectively. This detailed account of the Vexo X Pot project highlights the process, findings, and solutions implemented by our team to ensure optimal performance and client satisfaction.

Project Overview

The Vexo X Pot installation project in Plant Room P involved integrating ten units into the existing system to enhance water treatment and improve overall efficiency. The Vexo X Pot is designed to remove air and dirt from heating and cooling systems, thus prolonging the life of the system components and increasing operational efficiency. Our task was to install these units and ensure they functioned correctly within the system’s parameters.

Initial Installation

Our team began the project by installing the first nine of ten Vexo X Pot units. The installation process was meticulously planned and executed to minimize disruption and ensure seamless integration with the existing system. Each unit was carefully positioned and connected to the necessary piping and control systems. The final unit was scheduled for installation after confirming the operational stability of the initial nine units.

Unforeseen Challenge: Non-Return Valve Issue

During the installation and initial testing phase, we encountered an unexpected issue with the non-return valve (NRV). Specifically, with the Vexo X Pot online, the NRV would not close properly. This malfunction was a critical concern as the NRV is designed to allow fluid to flow in one direction and prevent backflow, which is essential for maintaining system integrity and performance.

Investigation and Analysis

Our team immediately initiated a thorough investigation to determine the cause of the NRV malfunction. After careful analysis, we identified several contributing factors:

1. Weight of the Flap: The weight of the NRV flap appeared to be affecting its ability to close properly.
2. Water Flow Pressures: The pressures exerted by the water flow across the surface of the NRV flap were influencing its operation.
3. NRV Position: The horizontal position of the NRV was a significant factor in its inability to function correctly with the Vexo X Pot online.

Innovative Solution: Repositioning the NRV

To address the issue, we proposed repositioning the NRV to enhance its operational efficiency. We recommended installing the NRV in a horizontal position and incorporating two stainless steel male/female (M/F) elbows. This adjustment aimed to balance the forces acting on the NRV flap and ensure it could close properly.

Our team promptly implemented this solution, repositioning the NRV and installing the stainless steel M/F elbows. This adjustment was completed with precision to ensure optimal alignment and functionality.

Testing and Verification

Following the repositioning of the NRV, we conducted extensive testing to verify the effectiveness of our solution. The tests included:

1. System Drain and Refill: We partially drained and refilled the system to simulate real-world operating conditions.
2. Dosing Pot Simulation: The dosing pot was simulated to assess its impact on the NRV operation and overall system performance.

During these tests, we monitored the NRV’s behavior closely, ensuring it operated as intended. The results were promising, confirming that the NRV closed properly and maintained its function with the Vexo X Pot online.

Continuous Monitoring and Follow-Up

Understanding the importance of sustained performance, we scheduled follow-up visits to monitor the system and ensure continued functionality. Over the course of two weeks, our team returned to Plant Room P twice to inspect the installation and verify that the NRV remained operational. During these visits, we confirmed that the system operated without any issues, and the NRV functioned as expected.

Conclusion

The Vexo X Pot installation project in Plant Room P presented IJB Engineering with a unique challenge, which we addressed through careful analysis, innovative problem-solving, and diligent testing. The repositioning of the NRV and the incorporation of stainless steel M/F elbows ensured the system’s optimal performance and highlighted our commitment to delivering high-quality engineering solutions.
