Operating Principle
During operation, the pump enables reverse circulation. Under atmospheric pressure, circulating fluid flows from the sedimentation tank to the well bottom through the annular gap. The rotary table drives the drill pipe and bit for drilling. The mud pump's suction creates negative pressure, drawing debris into the drill pipe's inner cavity and discharging it into the sedimentation tank. The settled fluid continues circulating into the well, completing the reverse circulation drilling process.
