Background technology
Along with the continuous development of China's marine economy, deep-sea exploration and development ability improves constantly, and particularly deep-sea mining and deep-sea oil exploration and development embodies more and more significantly for the demand of the heavy-duty motor that can work under abyssal environment.The deep-sea motor of the depth of water above 3000 meters often has the big characteristics of power density; and the raising of power of motor density is had higher requirement to winding temperature rise control; with regard to abyssal environment; traditional air-cooled and mode that utilize liquid circulation that the motor heat is taken away is restricted, and only depends on seawater free convection can not adapt to the motor development far away to the winding temperature rise designing requirement to the method for heavy-duty motor cooling.Therefore, press for a kind of new cooling means and solve deep-sea heavy-duty motor temperature rise control problem.
Patent " a kind of seabed motor cooling means and device " (publication number: CN102290923A), adopt double-casing motor shell and heat exchanger tube to constitute tube heat exchanger, cooling fluid in the motor as hot fluid in shell, seawater is managed intrastratal flow and the heat exchange of shell inner fluid as cold fluid, this motor cooling means can satisfy the seabed motor to the control requirement of temperature rise, but motor adopts double Shell and heat exchanger tube must cause motor volume between two-layer housing, it is big that weight becomes, with the deep-sea motor miniaturization, lightness contradicts, and this method adopts the scheme of seawater forced convertion in pipe, and the heat exchanging tube material has proposed higher requirement for anticorrosion.The present invention is directed to deep-sea motor to the requirement of temperature rise control, proposition with seawater as shell, the scheme that cooling fluid flows in heat exchanger tube in the motor, this scheme can satisfy deep-sea motor to the requirement of temperature rise control, the problem that can avoid patent (CN102290923A) to exist again.
Summary of the invention
At above-mentioned prior art problems, the present invention proposes a kind of deep-sea heavy-duty motor temperature rise control method and device, have under the prerequisite that does not change motor basic structure, can form the characteristics of cooling fluid forced convertion and seawater to make heat exchange, to satisfy the requirement to deep-sea motor miniaturization, lightness.
For achieving the above object, technical scheme of the present invention is:
A kind of deep-sea heavy-duty motor temperature rise control method: be placed on heat exchanger tube 2 in the seawater by being directly installed on the seabed, and the cooling fluid that is full of in heat exchanger tube 2 and the motor realizes heat exchange between seawater and motor, motor is cooled off.
Cooling fluid in described motor and the heat exchanger tube 2 is in lasting flow regime.
Motor pump chamber 3 interior impellers 4 rotations with motor coaxle that flow through of described cooling fluid realize.
Described cooling fluid is water glycol.
The moving greatly rate electric machine temperature rise control device in a kind of deep-sea, comprise motor housing 1, heat exchanger tube 2, be installed in the pump chamber 3 that has the gateway in the motor, be installed in impeller 4, electric motor end cap 5, motor output shaft 6 on the motor shaft, it is characterized in that: all be full of cooling fluid in motor and the heat exchanger tube 2, heat exchanger tube 2 is directly installed on the seabed and is placed in the seawater, heat exchanger tube 2 one ends communicate with perforate on the motor housing 1, and an end gos deep into motor by motor housing 1 and communicates with pump chamber 3 outlets.
Beneficial effect of the present invention is:
1, the present invention is owing to place heat exchanger tube in the seabed, and cooling fluid is communicated with heat exchanger tube is interior in the motor, has increased cooling fluid and seawater to make heat exchange area, improves heat exchange efficiency, and electric machine temperature rise can farthest be reduced.
2, the present invention has realized the forced-convection heat transfer of cooling fluid because impeller with motor coaxle is arranged in the pump chamber in placing motor, gives motor with cooling effect to greatest extent, makes motor have longer service life and thermal stability.
3, the present invention is because the import and export of pump all communicates with cooling fluid, and the impeller consumed energy only is used for overcoming the resistance of coolant flow, and consumed energy is not high.
4, the present invention is not owing to by cooling fluid forced flow heat exchange in the heat exchanger tube, when guaranteeing the heat exchange effect, need motor is carried out big transformation, and can satisfy the requirement of the miniaturization of deep water heavy-duty motor, lightness
5, the present invention is simple in structure, heat exchange efficiency is high, and the reliability height can take full advantage of existing motor and transform, and therefore, can effectively solve deep-sea heavy-duty motor temperature rise control problem, satisfies the requirement of deep-sea heavy-duty motor long-life and thermal stability.
