Swivel for water well drilling rig SDR-35S

Description: The swivel is used in rotary water well drilling rigs to supply drilling fluid to the drill string. The swivel consists of a body, shaft, flanges, nuts, bearings and seals. Specifications Max pressure 420 PSI Rotation speed 300 rpm Max axial load 13,000 lb Max torque 2,000 N*m Shaft water hole 35mm Weight 73 lb Stainless sleeves Stainless sleeves are installed on the swivel shaft to increase the service life. This prevents the shaft corrosion of at the points of contact with the seals. Sleeves have a ground-polished mirror outer surface. In case of wear, the sleeves can be replaced with new ones. The inner diameter of the sleeve and the outer diameter of the shaft are ground and precisely dimensioned. Therefore, after replacing the sleeves, the outer diameter is within acceptable limits. Bearings We use tapered roller bearings. They can work with axial and radial loads. The swivel can be used as a support block that absorbs strong shocks and vibrations and transfers them to the drilling rig carriage. In this case, the hydraulic motor or gearbox performs only the function of rotation. Four seal barriers The first barrier - PTFE bushings, prevents the passage of abrasive particles. They have tension on the internal and external diameters and, due to the elasticity of the material, provide a tight glide. Bushing width 16mm. When drilling with direct circulation, abrasive particles do not come into contact with other types of seals, and the service life of the swivel is significantly increased. The second barrier - Hydraulic polyurethane seals, can take high pressure. They allow the swivel to be used with a piston mud pump or the compressor with a hammer. The third barrier - Rotary shaft oil seals, provides general swivel tightness. The fourth barrier - Rotary shaft oil seals, installed in the flanges to ensure the tightness of the bearing chamber and prevent the penetration of dirt from the external environment. Connecting with the hydraulic motor shaft The swivel shaft has a bushing (without keyed connection), which can be installed inside to be connected with the shaft of the hydraulic motor or gearbox. Inside the bushing, you can make a hole with a keyway or splines yourself. The bushing outer diameter is 60mm. Connecting with the drilling rig carriage The swivel can be connected to the base plate of the drilling rig carriage using bolts and special holes. There are holes in the upper and lower flange, respectively, you can make a connection in the upper and lower part of the swivel, as shown below: Drill pipe connection For the drill pipe connection is used the adapter for threading. You can thread the end of the adapter yourself. The dimensions of the adapter are shown below: Flushing fluid supply The flushing fluid enters through a hole in the swivel body. The hole is threaded with BSP 2”. The aluminum Camlock connections are screwed into the body: Male (type F 2” BSP) + Female (type C 2”).
