الوصف

The WOODWARD 8923-1997 is a replacement kit, specifically designed for maintaining Woodward’s larger CPC-DX Dual Redundant Skid systems.

WOODWARD 8923-1997: CPC Replacement Kit (25 Bar, Zone 2, for CPC-DX Skid)

The WOODWARD 8923-1997 is an essential spare part for users of Woodward’s CPC-DX Dual Redundant Skids. It is not a complete functional unit itself, but rather a kit containing the necessary components to replace a single CPC (Current-to-Pressure Converter) unit within such a redundant skid system.

Product Overview

This part number is part of Woodward’s comprehensive service and support offerings, which ensure that critical industrial control systems can be efficiently maintained and repaired, thus minimizing costly downtime.

• Product Type: Replacement Kit
• Manufacturer: Woodward
• Part Number: 8923-1997
• Purpose: To replace one CPC (Current-to-Pressure Converter) unit within a CPC-DX Dual Redundant Skid.
• Compatibility: This specific kit is for CPC-DX skids designed for a 0-25 bar (0-363 psi) output pressure range and certified for Zone 2 hazardous locations.
• Benefit: It enables on-line repair or replacement of a faulty CPC unit within a redundant skid. This allows the overall system to continue operating with the remaining healthy CPC, thereby maintaining high availability and reliability.

Detailed Product Description

The Woodward 8923-1997 kit facilitates field repair and maintenance of a CPC-DX (Current-to-Pressure Converter – Dual Transfer) skid. A CPC-DX skid (e.g., part number 8918-116 for the 25 bar, Zone 2 model) typically comprises two CPC-II units operating in a master/slave or other redundant configuration. If one of these CPC-II units requires replacement due to a fault or as part of preventative maintenance, this kit provides the correct replacement unit and any associated necessary components.

• Integration with CPC-DX Skids: The CPC-DX system is designed for high reliability, allowing for bumpless transfer of control if one of its internal CPCs fails. This kit is crucial for restoring the full redundancy of such a system after a component failure, ensuring continuous operation.
• “Dirt Buster” Technology: The replacement CPC unit included in this kit features Woodward’s “Dirt Buster” (or “Silt Buster”) technology. This robust design makes the CPC highly tolerant to contaminated hydraulic oil (up to ISO20/16 cleanliness), a common challenge in industrial environments. This technology significantly contributes to the long-term reliability of the system.
• Zone 2 Rating: The kit ensures that the replacement components maintain the original system’s certification for Zone 2 hazardous areas. This is vital for safety and compliance in environments where flammable gases, vapors, or mists may occasionally be present.
• Enables On-Line Repair: A key advantage of the CPC-DX skid is its ability to allow for on-line replacement or repair of individual CPCs without shutting down the entire turbine or process. This kit directly supports and facilitates that critical capability, minimizing operational interruptions.

Typical Use

The WOODWARD 8923-1997 CPC Replacement Kit is typically used by maintenance personnel or authorized service providers in:

• Power Generation Plants: For routine maintenance or emergency repair of CPC-DX skids controlling steam turbines.
• Industrial Facilities: In any process requiring highly reliable and continuous operation of single-acting hydraulic actuators driven by a CPC-DX system.
• Scheduled or Unscheduled Maintenance: To replace a CPC unit that has reached its service life or has experienced a fault, thus restoring the full redundancy of the CPC-DX skid and ensuring system reliability.
