What is the crown block?
Crown block is a device located at the top of the oil platform or Derrick. It sits on the crown platform, which is a steel platform located along the top of the set. The crown block works in conjunction with a similar component, a travel block, which is located just below the crown platform. Together, these two systems are known as block and tools. While the block and tools system seems relatively simple to outsiders, it actually represents a critical part of the oil drilling process. These cables and pulleys sit on a steel frame that can be built into the Derrick structure. The Sheaves serves as a drill line and passes through the block of movement down to connect to the raised drum of the set. When the cables pass through the pulleys in one direction, they cause the oil drum to descend to the ground. When the cables pass over the pulleys in the opposite direction, the cause oil drum that raises back upwards and brings oil for collection. This travel block contains inner pulleys that are surrounded by steel to protectBoth pulleys and cables before corrosion.
The use of the Crown Block and the travel block significantly increases the strength of the oil stage. The pulleys position allows cables to withstand huge levels of strength and helps workers to drill deeper and extract more oil. Without a crown block, the oil derick would require much stronger and stronger cables. This would also require a more powerful and significant pumping system to work successfully. The use of the block and tools system provides a high degree of lever effect to raise and reduce the raised drum to maximize productivity and efficiency.
Depending on the size of the dericka and the depth to which it must drill, the oil set can use one or double crown block. While one block uses only one set of pulleys, the double deck model contains two sets. These pulleys are located at right angles together to create additional strength and strength.
One of the disadvantages of using the Crown Bloc design is its high maintenance requirements. These devices must remain lubricated to allow Salves to pass freely through the pulleys. Insufficient lubrication can lead to excessive friction that could cause cable failure or break.
