Service

GENERAL COMMENTS

When working on the compressor, care must be taken to ensure that contaminants (i.e. water from melting ice, dirt and dust) do not enter the compressor while it is being serviced. It is essential that all dust, oil or ice that has accumulated on the outside of the com- pressor be removed before servicing the compressor.

When servicing the compressor, all gaskets, O-rings, roll pins and lock washers must be replaced when reassembling the compressor.

PREPARATION OF UNIT FOR SERVICING

A)Shut down the unit, open the electrical discon- nect switch and pull the fuses for the compressor motor to prevent the unit from starting. Put a lock on the disconnect switch and tag the switch to indicate that maintenance is being performed.

B)Isolate the unit by manually closing the discharge Stop valve. Allow the unit to equalize to suction pressure before closing the Suction Bypass. After the unit has equalized to suction pressure and suction valve closed, use an acceptable means to depressurize the unit that complies with all Local, State and Federal Ordinances.

C)Remove drain plugs from the bottom of com- pressor housing and the discharge manifold On units equipped with Suction Oil Injection (SOI) manually open the SOI solenoid valve below the compressor. Drain the oil into appropriate con- tainers.

REMOVAL OF COMPRESSOR FROM THE UNIT

After preparing the unit for service, the following steps should be followed when removing the compressor from the unit:

A)Disconnect the motor drive coupling from the compressor input shaft.

B)Disconnect all gas and oil piping which is at- tached to the compressor. When removing the suction strainer on gas compression units, the suction line should be supported to prevent it from sagging.

C)Replace oil drain in compressor housing and dis- charge manifold after oil has stopped draining.

D)Remove all electrical connections to the com- pressor.

E)On compressors with mounting feet, loosen and remove bolts holding the compressor to the base.

Keep compressor alignment shims together and mark the locations with a permanent marker.

F)On compressors with C-flange the motor/C- flange/compressor assembly must be supported with a chain fall or other lifting device before the bolts holding the compressor to the C-flange adapter can be removed.

G)Install appropriate lifting eye into the threaded hole on the top of the compressor.

Verify unit is properly secured to avoid compressor from falling. Re-verify all piping and electrical are properly disconnected prior to lifting unit.

H)Lift compressor from the base, verify the amount of room needed for clearance and weight of the bare compressor when the compressor is removed from the unit.

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.
