Brief: This video provides a detailed walkthrough of the FC UM Type Ram BOP's fast maintenance procedures, focusing on the unique 'open bonnet, close ram' linkage system. You'll see a practical demonstration of hydraulic and manual ram opening methods, bonnet operation for quick access to internal components, and key inspection steps to ensure reliable well control performance in demanding oil and gas operations.

  • Designed for easy maintenance with hydraulically sliding bonnets for quick access to wearing parts.
FAQs:
  • What is the operational principle behind the bonnet and ram linkage?
    The system operates on the principle: 'opening rams closes bonnets, closing rams opens bonnets.' This precise hydraulic control provides labor-saving operation and facilitates fast maintenance access to internal components.
  • How do you perform maintenance on the ram blocks and wearing parts?
    For maintenance, first loosen the bonnet fixing bolts, then inject hydraulic oil into the BOP's closing oil passage to push the bonnets open. This provides direct access to the ram blocks and other internal components for inspection or replacement.
  • What are the different methods for opening the rams?
    There are two primary methods: Hydraulic Direct Opening injects 8.4-10.5MPa oil into the ram opening cavity to drive the piston open. Alternatively, with manual locking engaged, first rotate the handwheel counterclockwise, then back 1/8-1/4 turn before applying hydraulic pressure to open the rams.
  • What safety precautions should be taken during operation?
    Assign qualified personnel, maintain standardized operating pressures (≤3MPa for testing without string), never close blind/shear rams with string present, and for long-term sealing, hydraulically close rams, engage manual lock, and place warning tags.
