Deep Well Pump Drive Shafting

Abstract

The invention discloses a deep well pump transmission shaft system. The deep well pump transmission shaft system includes a pipe string, a transmission shaft and a connection mechanism. The transmission shaft is installed inside the pipe string. The connection mechanism includes a first connection component and a second connection component. A connecting assembly is used to connect the end faces of two adjacent pipe strings together, a second connecting assembly is used to connect the end faces of two adjacent transmission shafts together, and the second connecting assembly includes a mounting member, a clamping member and a coupling member. For any second connection assembly, both ends of the mounting member are respectively installed on two adjacent transmission shafts along the axial direction of the transmission shaft, and the coupling is sleeved at the connection between the two adjacent transmission shafts, The clamping piece is arranged on the outer peripheral wall of the transmission shaft along the axial direction of the transmission shaft, and the clamping piece is clamped between the coupling and the transmission shaft. In the present invention, the pipe string is used as the supporting body of the transmission shaft, the power is transmitted through the transmission shaft, and the segmented connection form of the pipe string and the transmission shaft is adopted to finally satisfy the long-distance deep well pump drive.

Description

technical field [0001] The invention relates to the field of deep well pumps, in particular to a deep well pump drive shaft system. Background technique [0002] A deep well pump is a device used to pump liquid cargo from the liquid cargo tank to the outside of the liquid cargo tank. Common deep well pumps usually include a pump body placed in the liquid cargo tank, a motor placed outside the liquid cargo tank, and a drive shaft set between the pump body and the motor. The drive shaft system is used to transmit the power output by the motor to pump body. [0003] Most of the existing deep well pump long-axis power transmission equipment is a vertical single-suction multi-stage centrifugal pump. The impeller is installed below the dynamic water level in the well, and the power machine is installed on the well. The impeller is driven to rotate in the diversion shell through the long-axis transmission. The water flows along the flow channel between the diversion shell and the...

Problems solved by technology

[0004] However, the existing long-axis power transmission equipment of common deep well pumps uses the long axis for direct transmission, and the direct transmission of the long axis will make the transmission distance limited, so that it cannot meet the long-distance power transmission for product oil tankers and chemical tankers.
