FIELD: machine building.

SUBSTANCE: invention refers to machine building industry and can be used in systems of drilling machines, and namely for connection of rotating base of rods with fixed sleeve of drilling machine, via which air-and-water mixture is supplied. Swivel of drilling machine includes an adapter for sleeve, housing and a nipple installed in the housing. Housing is provided with built-in sleeve adapter. Rod adapter is crewed on the nipple end. Flanges are made on rod adapter and nipple so that housing and damper rings can be installed between them. Cuffs supported with rings are installed between internal wall of housing and external wall of nipple.

EFFECT: invention allows reducing the wear of swivel seal; besides, reducing the hazard of emergency air leak from swivel of drilling machine and therefore, improving reliability and increasing service life of drilling machine swivel, thus considerably reducing the costs for its repair and service.

Swivel // 2425951

FIELD: oil and gas industry.

SUBSTANCE: swivel includes base, sleeve, housing, two rolling bearings and collars installed between the base and sleeve and is equipped with a cavity located in central channel. Cavity on the supply side of drilling fluid is interconnected with central channel by means of ejector to form in it the negative pressure during pumping of drilling fluid. Formation of negative pressure in the cavity allows excluding direct contact of drilling fluid with collars and sufficiently decreasing the negative influence of abrasive particles contained in drilling fluid for the period of service life of collars and sleeve. In addition, base has channels for discharge of drilling fluid from collars in case of leakage when there is no flow of drilling fluid. Channels allow excluding penetration of drilling fluid into rolling bearings and warning of the necessity of performing collar compression.

EFFECT: proposed swivel design allows without any sufficient costs improving reliability and enlarging service life of its components.
