The main purpose of research is reduction of corrosion of the main band brake components ( frictional plates – brake flanges ) which are used in oil and gas drilling rigs and so reduction of the stress on the main brake components by increase the braking torque for the auxiliary hydrodynamic brake, the frequent maintenance for the main brake components lead to time loss and increasing in the total cost of well drilling.
The research based on making of mechanical or chemical instrument be able to increase the braking torque for the auxiliary hydrodynamic brake.
The laboratory experiments show the using of inclined hydraulic blades with certain angle and creating of pressure in brake chamber and so water treatment by chemical materials which increase the water density and viscosity are important instruments be able to increase the braking torque for the auxiliary hydrodynamic brake in drilling rig.
