Installation

will result in a flexing element that is centered and parallel to its mating flange faces. Move the con- nected equipment to accomplish the above.

NOTE: The disc pack is designed to an optimal thick- ness and is not to be used for axial adjustments.

See documentation that came with the coupling for complete specifications.

3.Angular Alignment. Rigidly mount a dial indicator on one hub or shaft, reading the face of the other hub flange, as shown on next page. Rotate both shafts together, making sure the shaft axial spacing remains constant. Adjust the equipment by shim- ming and/or moving so that the indicator reading is within .002 inch per inch of coupling flange.

4.Parallel Offset. Rigidly mount a dial indicator on one hub or shaft, reading the other hub flange out- side diameter, as shown in Figure 3. Indicator set-up sag must be compensated for. Rotate both shafts together. Adjust the equipment by shimming and/ or moving so that the indicator reading is within

.002 inch per inch of the axial length between flex elements. See drawing below.

Note: If the driver or driven equipment alignment specification is tighter than these recommendations, the specification should be used. Also, be sure to compensate for thermal movement in the equipment. The coupling is capable of approximately four time the above shaft alignment tolerances. However, close alignment at installation will provide longer service with smoother operation.

E. Final assembly

With the coupling in good alignment the bolts will fit through the holes in the flanges and the disc packs more easily.

1.If the coupling arrived assembled, the disc packs are still attached to the center ring. Before tak-

Note: Alignment of C-Flange Units should be checked when compressor or motor are replaced.

ing the discs packs off, first install one hub bolt through each disc pack and secure with lock out. This will help when the pack is reinstalled late. If the coupling was shipped disassembled, the bolt through the pack is not required as the discs in the pack are factory taped together.

2.Remove the long bolts. Mount the disc packs on the hubs with one bolt through the disc pack aligned with a clearance hole in the hub. Install the short bolts through the hub, disc pack, bevel washer or link, and secure with a lockout.

NOTE: All bolt threads should be lubricated. A clean motor oil is recommended. On size 226 and larger, a link must be put on bolt first. Remove the disc pack alignment bolt. Proceed to mount the second disc pack to the other hub in the same way.

3.Position one set of short bolts in each hub on top. Now slide the center ring down into place straddling the short bolts with the center ring bushings. If coupling is dynamically balanced, the center ring match marks must lineup with both hub match marks. When one bushing is in-line with the hole in the disc pack, slide one long bolt through washer or link, disc pack, center ring, disc pack, washer or link, and then secure with a locknut. On size 226 and larger a link must be put on the bolt first. Now install the rest of the long bolts in the same manner.

Emerson VSR, VSM, VSS service manual Installation

VSS, VSM, VSR specifications

Emerson VSM, VSR, and VSS are advanced technologies designed for process automation and control, often utilized in industrial applications. These systems are part of Emerson's broader portfolio of solutions aimed at enhancing operational efficiency, safety, and reliability.

The Emerson VSM, or Valve Signature Management, focuses on the digital management of valves within a system. One of its main features includes advanced diagnostics that monitor the health and performance of control valves. This technology allows for predictive maintenance, ensuring that valves operate at peak efficiency and reducing the risk of unexpected failures. The VSM utilizes a combination of smart sensors and actuators to gather data, enabling real-time analytics that can enhance decision-making and operational strategies.

On the other hand, VSR, or Valve Status Reporting, enhances visibility into the operational state of valves in real time. This system provides operators with critical updates and alerts related to valve conditions, significantly reducing response times to potential issues. The VSR technology integrates seamlessly with existing control systems, allowing for easier implementation and minimal disruption to ongoing operations. The reporting capabilities feature user-friendly dashboards that present complex data in a straightforward manner, empowering operators to make informed decisions quickly.

The Emerson VSS, or Valve Service Solutions, complements the VSM and VSR by focusing on the maintenance and support of valve systems. This offering includes comprehensive service packages that range from routine maintenance to advanced troubleshooting and repair. The VSS is designed to improve the lifespan of valves through proactive service, ensuring reliability and minimal downtime. Emerson’s trained technicians leverage predictive analytics derived from VSM and VSR data, allowing for timely intervention before issues escalate.

In summary, Emerson’s VSM, VSR, and VSS technologies work together to create a robust ecosystem for valve management in industrial settings. The combination of advanced diagnostics, real-time reporting, and comprehensive service solutions provides operators with a powerful toolkit aimed at optimizing performance and ensuring operational reliability. With these technologies, companies can embrace digital transformation, reduce operational risks, and improve overall process efficiency, leading to a safer and more productive environment. Each component plays a crucial role in empowering industries to meet the challenges of modern automation and maintain competitive advantages in their respective markets.
