Drilling Accessories Swivel
Introduced the use of the Swivel
The swivel is also called the "rotary live", "broken", it is very
important for key components of the drill pipe, drill, its top and
drill the winding wire connection, the bottom and drill pipe
connections, as the primary winding of wire rope, drive the rotary
digging drill pipe and drill of raising and lowering, and work in
the power head rotation, bit to jilt soil, bear the torque drill
pipe, through its own spin, remove the wire rope for drill pipe
rotation torque transmission, such as to prevent the occurrence of
kink, curly, steel wire rope for torsional fracture, etc.,
resulting in major accidents.
So, be introduced must have enough tensile strength, and under the
great tension with flexible rotation ability.
Fault diagnosis and removing
|Item||Fault||Possible reasons||eliminating measures|

|Under the joint bending plastic deformation, etc||replace|
|2||Unable to refill lubricants||Oil plug||cleaning|
|No grease lubricator||Adding grease lubricator|
|Oiler damage||Repair or replace the oiler|
|3||Grease leak||Grease a thin||Change of more viscous oil|
