The DY-A-FLEX clutch is a component specifically designed for use in National Oilwell Drawworks machinery. It’s a type of air clutch, often referred to as RUBFLEX DY-A-FLEX clutch, that’s interchangeable with National Oilwell’s Dy-A-Flex clutch. The clutch plays a crucial role in the drawworks, which are the hoisting mechanisms used in oil drilling rigs.
Here’s a more detailed breakdown:
Drawworks:
These are the heart of the drilling rig’s hoisting system, responsible for raising and lowering the drill string and other heavy equipment.
DY-A-FLEX Clutch:
This is a type of air-actuated friction clutch, often used in conjunction with drum shafts in drawworks.
RUBFLEX DY-A-FLEX Clutch:
specifically mentions the RUBFLEX DYALFEX clutch as being interchangeable with National Oilwell’s Dy-A-Flex clutch.
Function:
The clutch connects and disconnects the engine’s power to the drawworks drum, allowing for controlled lifting and lowering of the drill string and other heavy loads.
High/Low Speed:
Drawworks often use different clutch settings (high or low speed) to match the required torque and speed for various drilling operations. The DY-A-FLEX clutch, or its equivalents, can be used in both high and low-speed applications within the drawworks.
