Description
Technical field
The present invention relates to technical field of motors, more particularly, relate to a kind of water-cooled machine and motor cooling method.
Background technology
The medium-and-large-sized motor type of cooling is varied, comprises air cooling, liquid cooling, evaporative cooling etc., but in medium-and-large-sized motor application, comprehensive cooling system ability and Financial cost are main with air cooling mainly.Air cooling is structurally simple, and cost is easy to maintenance; These remarkable advantages make air cooling at first obtain using and development, still, and along with the increase of capacity motor; Amount that the motor feels hot is also increasing, and need to strengthen cooling and just must strengthen ventilation quantity, thereby increase draft loss; Reduce electric efficiency, the motor liquid cooling system produces thereupon.
About motor liquid cooling mode, as far back as 1917, Hungary ridge time thatch factory just once made the type of cooling of traction electric machine with transformer oil.1956, Britain began to adopt the cooling motor stator winding of purifying waste water.Winding adopts water-cooled quite general at present.The specific heat of liquid, thermal conductivity ratio gas is big, so the heat-sinking capability of liquid cooling greatly improves than air cooling.Water is good coolant, and it has very big specific heat and heat-conducting system, and cheap and non-toxic is not fire-retardant, no explosion hazard, advantage such as cooling effect is remarkable.
Two kinds of forms of the general branch of the water-cooling system of water-cooled machine; A kind of is to add but device of water-air cooling in the motor outside; The motor internal heat takes the empty cooler of external water to by the inner air circulatory system, and the heat exchange of the aqueous medium in this completion and external circulating system, thereby constantly the motor heat is taken away; Another kind is directly to offer water channel in base inner, directly motor is cooled off, i.e. support formula water-cooled machine.
The support of support formula water-cooled machine can adopt the steel plate welding and cast two kinds of technologies.For welded-steel plate construction; Its manufacturing process selects for use suitable steel plate ring to become simple barrier part earlier; The barrier part internal diameter is slightly less than frame diameter; And then block length bar steel plate of barrier part outer wall welding, steel plate direction (axially tank) or tangential (spiral tank) is vertically looked concrete structure and is decided, and then these tank outsides are sealed into water channel with monoblock or several piece steel plate with tank again.The head and end of these water channels has intake-outlet, during work, meets the external water circulation system, realizes the motor cooling purpose.Welding water cooling base intensity is high, and rigidity is high, advantages such as long service life, but material and processing cost are high.Casting water cooling base structure and Welding Structure basically identical; But material cost and manufacturing cost reduce greatly; Shortcoming is to be easy to generate unforeseen casting flaw, and for example cast frame needs follow-up machine work to offer intake-outlet, if the casting bubble appears in Working position; Will produce sealing problem, even this support can not be used.
The water cooling base of two kinds of technologies also has some common shortcomings except that above-mentioned characteristic.Water directly contacts with support; Will produce corrosion to support; Because support also is directly to contact with stator core directly, in case support because of corrosion seepage takes place, will destroy Motor Stator Winding Insulation rapidly; Damage motor, and the initial stage of corrosion failure can not be found ahead of time in periodic maintenance; The maintenance technology difficulty is big, no matter adopt which kind of channel structure, water channel all has certain-length, and its maintenance is had quite big degree; Maintenance cost is high, in case find that water channel has the corrosion failure phenomenon, not bad for Welding Structure; Can excise peripheral steel plate in corrosion place; Corrosion place is repaired and preservative treatment etc., but these can occur same problem again very soon through the places of safeguarding, cast frame then has only and more renews a kind of way of part.For the more and more littler medium-and-large-sized motor of profit margin, the high maintenance cost that therefore produces very likely surpasses its profit, a kind of structure if can be arranged under the prerequisite that does not reduce cooling, reduces maintenance cost greatly, will have very large application prospect.
