Technical field
The present invention relates to a kind of motor cooling technology field, more particularly to a kind of large-size machine cooling system.
Background technology
Motor is military, and purposes is wide in terms of industry and agricultural, is to provide the capital equipment of power.Large-size machine rotating speed
Height, power is big, accompanying problem is that the loss of unit volume is big, produces heat greatly, radiating is difficult.The temperature of motor permanent magnet
Liter is too high to cause the demagnetization of permanent magnet, so effective cooling of large-size machine is even more important, it is to ensure electric efficiency and Gao Ke
By the premise of property.
China is at present in middle and small motor field, the preferably double cooling by water modes of radiating effect.But motor is towards appearance
Amount maximization direction is developed, and the efficient type of cooling is increasingly subject to the attention of people.Water cooling is cold mode in one kind, is easily produced
Incrustation scale deposits blocking water channel, it is necessary to periodic cleaning, while it should also be noted that often to change water, so as not to over time with it is various from
Sub increases and corrosion electrical motor.(the automobile water-based cool electric machine Temperature calculating of Chen Yanxi, 45KW and design of Cooling System [D], Ha Er
Shore Polytechnics, 2013)
At present, motor water-cooled device have ignored cooling water circulation all in the cooling effect of raising water cooling plant of trying one's best
During temperature rise increase and cooling, i.e., without to greatest extent utilize cooling water circulation so that cause energy consumption for cooling it is higher and
Cooling water waste.(Zhong Jinfeng, a kind of cooling devcie of motor [P], China, utility model patent, CN 204928483 U, 2015)
A kind of large-size machine cooling system of the present invention, can improve the cooling effectiveness of large-size machine, extension motor
Life-span.
The content of the invention
The present invention provides a kind of large-size machine cooling system, using cooling technique and motor internal be axially air-cooled and single-screw
Water cooling is cooled down to large-size machine, strengthens cooling effect.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of large-size machine cooling system, it is characterised in that：The cooling system include water supply installation, water correction device,
Air supply device, motor and water cooling plant.The water supply installation includes industrial cycle pond and water pump；The water correction device bag

Further, described water gives parallel resistance heater after filter, and the resistance heater is connected with stop valve
Connect.
Further, described Na-ion exchanger is connected to after water gives filter, and degassing tank is handed over installed in sodium ion
After parallel operation.
Further, velometer is connected between described air blower and motor, the cooling water temperature shown according to thermometer
The flow velocity of appropriate regulation air.
Further, the cooling water of described cooler is conveyed by water pump, then is flowed into industrial cycle pond.
Further, described inner shaft of motor is that 1/3-3/5 groove depths are left near stator slot to cooling air channel
Axial ducts.
Further, single-screw water-cooling channel pitch is 9mm in described motor, and channel cross-section is rectangle, a length of
8mm, a width of 3mm.
The beneficial effects of the invention are as follows water correction device reclaimed water of the invention gives filter tentatively to remove grain in cooling water
Solid particle of the degree more than 5 microns；Na-ion exchanger replaces the cations such as calcium and magnesium free in cooling water, in order to avoid produce carbonic acid
The blocking water channel such as salt crust and sulfate scale；The CO that degassing tank is dissociated by the wind-force of blower fan in stripping cooling water2, because in water
Contain a certain amount of CO2If, CO2Carbonic acid is produced with water, can corrosion electrical motor；Rotor and stator are provided with axially air-cooled logical
Road and single-screw water-cooling channel, air-cooled and water cooling are combined, and the heat that more efficiently motor can be produced is taken away in time, it is ensured that
The efficient long-term stable operation of motor.The system can realize the efficient cooling to large-size machine, effectively improve motor transmission efficiency,
Extend the service life of motor.
