Drilling rig disc brake hydraulic station accumulator

What is the main brake of a drilling rig?

The main brake of a drilling rig is the mechanical band brake or the hydraulic/ mechanical disk brake system. As the name implies, the primary method of stopping the draw-works drum is by the use of the main brake. It is, therefore, essential that the driller is familiar with its operation, adjustment and maintenance.

What is a disk brake system?

The disk brake system consists of three major components: The Disks. The system uses two hard-faced discs with an internal water jacket on either side of the main drum. The brake system disc thickness will vary from two to three inches depending on the drawworks size. Disc diameter usually is four to five inches larger than with brake bands.

What is drawworks brake system?

The Hydraulic System. Drawworks Brake System can be divided into: The main brake of a drilling rig is the mechanical band brake or the hydraulic/ mechanical disk brake system. As the name implies, the primary method of stopping the draw-works drum is by the use of the main brake.

How does a disk brake work?

Since it is a hydraulically operated system, the brake can be controlled from positions remote from the traditional driller’s position without complicated mechanical systems. The operation of a disk brake is identical to that of a band brake; manipulate the lever to operate the brake.

What is a magnetic particle drawworks brake system?

Figure 10 is a cross-section of a magnetic particle drawworks brake system. This brake consists of a housing containing coils, a rotor, and a certain quantity of iron powder. Magnetic barriers and magnetic seals prevent the magnetic field, created when the coils are energized, from scattering.

How thick is a brake system disc?

The brake system disc thickness will vary from two to three inches depending on the drawworks size. Disc diameter usually is four to five inches larger than with brake bands. Depending on the size of the drawworks, there are four or six brake system caliper assemblies (two or three on each disc).
