Description
Technical field
The present invention relates to technical field of motors, more particularly, relate to a kind of water-cooled machine.
Background technology
At present, the water-cooling system of general water-cooled machine is divided into two kinds of forms, a kind of is to add but device of water-air cooling in the motor outside, the motor internal heat takes but device of outside water-air cooling to by the inner air circulatory system, and this finish with external circulating system in the heat exchange of aqueous medium, thereby constantly the motor heat is taken away; Another kind is directly to offer water channel in base inside, 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, then at block length bar steel plate of barrier part outer wall welding, steel plate direction (axially tank) or tangential (spiral tank) is vertically decided on concrete structure, then with monoblock or several piece steel plate tank is sealed into water channel in these tank outsides.The head and end of these water channels has water inlet, during work, meets the external water circulation system, realizes the motor cooling purpose.Welding water cooling base intensity height, rigidity height, advantages such as long service life, but material and processing cost height.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, for example cast frame needs following process 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 seepage takes place because of corrosion in support, 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; Maintenance difficulties is big, no matter adopt which kind of channel structure, water channel all has certain-length, and its maintenance is had sizable difficulty; The maintenance cost height, 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 anti-corrosion treatment etc., but these places through safeguarding again can the same problem of very fast appearance, and cast frame then has only and more renews a kind of method of part, same maintenance cost height.
The cooling of motor bearings also is faced with same problem, particularly in the hot operation zone, the heat that produces during owing to motor self running adds heat credit, be delivered to the electronics rotor as heat through rollgang at the high-temperature product of steel rolling mill, cause the bearing temperature on the rotor very high, the motor bearings lubricant grease produces and burns, and loses lubrication, it is stuck that motor bearings is damaged, have a strong impact on production, price for repairing is big, the cost height.
For the more and more littler electromechanics trade of profit margin, therefore the high maintenance cost that produces very likely surpasses its profit, a kind of cooling system if can be arranged under the prerequisite that does not reduce cooling effect, reduces maintenance cost greatly, will have very large application prospect.
Summary of the invention
In order to solve existing water-cooled machine processing technology complexity, technical problem that maintenance cost is high, the invention provides a kind of processing technology simple, easy for installation, be difficult for permeating, maintenance cost is low, the water-cooled machine of good cooling results.
In order to address the above problem, the present invention realizes by the following technical solutions: comprise support, it is characterized in that: the inner surface at support middle part is close to stator core, same periphery evenly is provided with many dismountable cooling water pipes in the support middle wall, motor shaft is provided with around the many siphunculus of the water inlet of support to an end, motor shaft is provided with around the many siphunculus of the draining of support outer surface to the other end, the many siphunculus of described water inlet are provided with water inlet, the many siphunculus of draining are provided with discharge outlet, and the two ends of described cooling water pipe are communicated with many siphunculus of water inlet and the many siphunculus of draining respectively.
The quantity of cooling water pipe described in the present invention is no less than 18.
Among the present invention; in order to carry out spacing to cooling water pipe, many siphunculus of intaking, the many siphunculus of draining and protection; cooling water pipe places in the support wall; the many siphunculus of many siphunculus and draining of intaking are made up of support, waterproof washer, end cap; this structure can effectively be protected cooling water pipe, many siphunculus of intaking, the many siphunculus of draining; and there is processing simple, advantage such as motor size is little.
Further improvement of the present invention; outer periphery in the rotor bearings at both ends is equipped with the cavity that can hold cooling water, and cavity has cooling water inlet and coolant outlet, can well reduce the temperature of motor and bearing thereof; protection motor and bearing thereof, the generation and the maintenance cost of minimizing fault.
Further improvement of the present invention is exported an end at the non-power of rotor cooling fan is set, and can promote extraneous air and the heat exchange of electric machine stand shell, and the heat exchange of extraneous air and cooling water pipe improves radiating efficiency, reduces motor temperature.
Technique effect of the present invention is: radiator portion of the present invention is divided into three compound parts independently of one another and organic, the one, independently cooling water pipe contacts with support, can effectively avoid the cooling fluid burn into to damage the motor major part, compare with traditional support, can detect the corrosion situation easily on the one hand, even the corrosion situation takes place on the other hand, as long as change the cooling water pipe of leakage, support does not need in the time limit to consider to change at electrical machinery life substantially, greatly reduces the maintenance cost of motor; Cooling water pipe adopts ordinary copper (aluminium) pipe by machining two terminal circle screw thread, and technology is simple, and cost is low, and easily standardization; The 2nd, motor bearings cooling system independently, outer periphery in the rotor bearings at both ends is equipped with the cavity that can hold cooling water, cavity has cooling water inlet and coolant outlet, can well reduce the temperature of motor and bearing thereof, protection motor and bearing thereof, the generation and the maintenance cost of minimizing fault; The 3rd, export an end at the non-power of rotor cooling fan is set, can promote extraneous air and the heat exchange of electric machine stand shell, the heat exchange of extraneous air and cooling water pipe improves radiating efficiency, reduces motor temperature.By the design and installation of these three independent cooling devices, can improve the cooling effect of motor greatly, can make the work of motor long-term stability.
