Abstract

The invention discloses a power transmission device for an immersed pump and a power transmission tube thereof, belonging to the field of a hydraulic system. The power transmission device for the immersed pump comprises a hydraulic pump station, an immersed pump head and a power transmission tube, wherein the hydraulic pump station comprises a hydraulic pump; the immersed pump head comprises an immersed pump and a motor for driving the immersed pump; one end of the power transmission tube is communicated with the hydraulic pump, and the other end of the power transmission tube is communicated with the motor; the power transmission tube comprises a high-pressure oil inlet tube and a low-pressure oil return tube which is arranged outside the high-pressure oil inlet tube; a low-pressure oil return cavity is enclosed by the high-pressure oil inlet tube and the low-pressure oil return tube; a supporting ring is arranged between the outer wall of the high-pressure oil inlet tube and the inner wall of the low-pressure oil return tube. The power transmission device for the immersed pump has high stability and good reliability and is convenient to mount and maintain. The power transmission tube has the characteristics of high rotation speed, long distance and high power.

Description

technical field [0001] The invention relates to the field of hydraulic systems, in particular to a power transmission pipe and a power transmission device for a submersible pump. Background technique [0002] The long-axis power transmission device for submersible pump is used to realize the power transmission between the hydraulic pump station on the deck of the oil tanker and the submersible pump of the liquid cargo bilge, and is the key equipment for the power transmission of the submersible pump of the oil tanker. [0003] The existing long-axis power transmission device includes a long-axis power transmission tube, a motor and a submersible pump head. The long-axis power transmission tube includes a sleeve and a rotating shaft located in the sleeve. One end of the rotating shaft is connected to the motor, and the rotating shaft The other end of the pump is connected to the submersible pump head, and the motor transmits power to the submersible pump head through the rota...
