Problems solved by technology

Generally, the power of the underwater motor installed on the trenching machine is about 300kw, and the efficiency of the motor is generally 90%-93%, so that each motor has a heat generation of 21-30kwh, and the temperature inside the motor will rise rapidly. In the underwater environment, the surrounding water will take away part of the heat, but it still cannot meet the heat dissipation requirements of the motor

Abstract

The invention discloses a heat dissipating system of a high-power underwater oil-filled motor. The heat dissipating system comprises a heat exchanger and a hydraulic pump. An inlet and an outlet of a first loop of the heat exchanger are communicated with a motor cabin respectively, the hydraulic pump is arranged on a pipeline used for connecting the outlet of the first loop and the motor cabin, an inlet of a second loop of the heat exchanger is communicated with a water outlet of a water pump through a pipeline, the water pump is driven by the motor, and water output by the water pump can flow through the second loop. Hydraulic oil in the motor cabin can flow through the first loop of the heat exchanger under the driving of the hydraulic pump, and the water and the hydraulic oil complete heat exchanging in the heat exchanger, and therefore the motor is cooled. The heat dissipating system can well conduct cooling on the high-power underwater oil-filled motor.

Description

technical field [0001] The present application relates to the technical field of seabed operation, and more specifically, relates to a cooling system for a high-power oil-filled underwater motor. Background technique [0002] Submarine pipeline trenching is to lay the submarine pipeline according to the predetermined route first, and then use the submarine trenching machine, usually a jet trenching machine to ride on the pipeline, spray high-pressure and large-flow water to wash away the sediment at the bottom of the pipeline, so that The pipe sank into the ditch. [0003] High-power oil-filled underwater motors and water pumps are important components of jet trenchers, and the efficiency and performance of the motors are the key factors that affect jet trencher trenching capabilities. Generally, the power of the underwater motor installed on the trenching machine is about 300kw, and the efficiency of the motor is generally 90%-93%, so that each motor has a heat generation ...
