This block is a set of sheaves (pulleys) that move up and down in the derrick. The drilling line is threaded (reeved) over the sheaves on the crown and through the sheaves in the traveling block. This provides a significant mechanical advantage to the drill line, enabling it to lift heavy loads of pipe and casing. The. .
The size of the groove should be the same as the diameter of the drilling line to deliver the proper support. A tiny pulley groove could cause high friction. Furthermore, it can cause. .
Periodic inspections: The Rig Traveling Block, as with all Hoisting equipment, must be inspected according to the manufacturer’s recommendations and API RP 8B or related ISO (International.

[pdf] Both high-pressure mud pumps are utilized on rigs to circulate the drilling fluidaround. Each type, however, has its operating limits,. .
The speed of the piston is not constant during the suction and discharge strokes. During each stroke, the speed increases from zero to maximum at approximately the halfway position. .
Mud pumps must be equipped with pressure relief valves. These valves prevent too high a pressure from being built up in the circulating system. The relief valves most.
