API Top Drive Flushing Pipe Varco High Press Drilling Rig Spare Parts

Washpipe Description of Drilling Rig Spare Parts:

The top drive is a key component combing the function of the swivel and Kelly drilling system, in contrast to the Kelly and rotary table drilling system, which drives the drill string from the top end. In contrast to the Kelly drilling system, it provides many advantages such as more drill pipe handling height which due to higher safety factors during the complicated well-bore condition, the capacity of drilling triples which leads to shorter connecting time and higher drilling efficiency, longer ream and back-ream height to increase the safety during handling of down-hole complexity. Function: The faucet flushing packing system reduces the effective differential pressure by providing pressurized lubricant to the low-pressure side of the seal to increase seal life. The pressure of the high-pressure lubricating oil is predetermined according to the proportion of the mud. The value is between the mud pressure and the atmospheric pressure. Usually, each sealing ring is subjected to the same pressure difference. The pressure of the lubricating oil is generally lower than the mud pressure, preventing the lubricating oil from excessive pressure and leaking.
