Description

 

Dual swivel consists mainly of shell, central pipe, packing device, pneumatic motor, gooseneck, and bail, etc. The central pipe is fitted in the shell through bearing and upper & lower cover. The lower end of central pipe is connected to drill pipe joint, and the upper end is connected to packing device. The bail is connected to shell by bail pin, and hung on rotary hook. The gooseneck is fitted on the top of upper cover with its outer end connected to vibration hose. A Packing device is installed between the gooseneck and central pipe, so that enable the high pressure mud to flow to the central pipe and ensure it is sealed and not leaked. The pneumatic motor is mounted onto the upper cover, which will drive the central pipe to rotate after slowing down by gas control friction clutch and gear, delivering its lock clasp capability.
Matched with standard bail and Double male buckle alloy steel pup joint.
The structure of wash pipe and Packing device is cassette, which can be rapidly replaced on drill floor without detaching the hose and gooseneck.
The separate through-hole on the top of goose neck provides channel for logging wire rope.
