Negative Pressure Debris Catcher

Vacuum negative pressure cleaning system is used to recover debris in the well. When pumping fluid, when the fluid flows out of the basket nozzle, a vacuum is formed in the debris chamber of the tool, and the fluid carrying debris is sucked from the bottom of the tool. The fluid carrying the debris passes through the internal filter of the tool. The filtered liquid is inhaled and circulated again. The debris remains in the chip bearing cylinder inside the tool and is carried to the surface with the tool.

APPLICATION
Vacuum negative pressure cleaning system is used to recover debris in the well. When pumping fluid, when the fluid flows out of the basket nozzle, a vacuum is formed in the debris chamber of the tool, and the fluid carrying debris is sucked from the bottom of the tool. The fluid carrying the debris passes through the internal filter of the tool. The filtered liquid is inhaled and circulated again. The debris remains in the chip bearing cylinder inside the tool and is carried to the surface with the tool.

FEATURES AND BENEFITS
1. Prevent debris buildup in the subsea blowout preventer;
2. Metal chips are not suspended in drilling or milling fluids;
3. All chips can be captured underground;
4. Can be used with various non-hydraulic milling tools;
5. Can be used to remove large amounts of debris at the bottom of the well;6. Lower mud costs;
7. Increased debris capacity;
8. Tool performance is not affected by mud yield value and viscosity;
9. Capture chips during milling operations.
