Abstract
The utility model discloses a closed type forced ventilation indirect air-cooling electromagnetic speed-adjusting motor and an electromagnetic speed governor, which integrate the advantages of an open type natural air cooling and a closed type water cooling. A closed type forced ventilation indirect cooling device is adopted by the utility model to carry out indirect air cooling to the electromagnetic speed governor. The closed type forced ventilation indirect cooling device makes use of the cold air created by a fan which is guided and forcibly introduced into a cooling pipe to be cooled. The utility model is characterized in that a cooler which is provided with a cooling pipe is assembled together with an electromagnetic adjustor, and the cooler and the electromagnetic adjustor are sealed off by seal covers. The utility model makes use of the rotary motion of an electromagnetic pole inner the electromagnetic adjustor to make an air cycle circulation inner the seal covers, and then obtains an exchange of heat. The utility model can be designed as a waterproof and dustproof type, an anticorrosive type or an anti-explosion type. The utility model is suitable for motors of large size, middle size or small size, and can also be made into a stand-alone cooling device for the electromagnetic speed governor.
Description
The utility model relates to the cooling device of a kind of electromagnetic varispeed motor and electromagnetic speed regulator.
At present, open type natural wind cold mould and two kinds of methods of closed water-cooling type are mainly adopted in the cooling of electromagnetic varispeed motor and electromagnetic speed regulator, open type natural wind cold mould is because speed regulator electrode space and extraneous directly UNICOM, dust and pernicious gas enter the buncher space, perishable getting rusty, and cause obstruction easily, the speed regulator life-span is short; Simultaneously, natural air cooled weak effect is unsuitable for high-power model motor.Closed water-cooling type need be established complicated water supply installation, the production cost height, and in a single day cut off the water, be easy to generate accident.
In order to overcome above deficiency, realize dustproof anticorrosive, increase the service life, to raise the efficiency, the utility model purpose is a kind of closed forced ventilation indirect air cooling device of design, and electromagnetic speed regulator is cooled off.Its structure is as shown in drawings:
Fig. 1: electromagnetic varispeed motor schematic diagram.Wherein: 1---alternating current motor, 2---electromagnetic speed regulator, 9---load, 10---the speed measuring motor winding, 11---the electromagnetic pole space, 12---the active rotation electromagnetic pole, 13---driven electromagnetic pole, 14---direct-flow magnet exciting coil.
Fig. 2: the electromagnetic varispeed motor schematic diagram that has cooling device.Wherein: 3---blast apparatus, 4,5---wind scooper, 6---seal bootr, 7---cooling duct, 8---the cooling device space.
Fig. 3: cooling device cooling duct sectional view.
The utility model is the cooling device of relevant electromagnetic varispeed motor and electromagnetic speed regulator. It comprises: produce the blast apparatus 3 of high-speed air flow, wind scooper 4,5, seal bootr 6, cooling duct 7, and cooling device space 8. Seal bootr 6 is fixed on the electromagnetic speed regulator shell, can weld or other securing member connection. Cooling duct 7 passes the cooling device space 8 that seal bootr 6 and seal bootr and electromagnetic speed regulator shell form, and two communicates with atmosphere, but is hedged off from the outer world. Cooling duct can be that parallel tubular type or other shapes, form are arranged, and its quantity and length are decided on motor power (output). Blast apparatus 3 can utilize the fan of ac motor itself, also can establish in addition air blast and wind scooper. Its operation principle is as follows:
Blast apparatus 3(accompanying drawing is an example with the fan of motor own) generation high speed cold wind A
1, by wind scooper 4,5 guiding process cooling ducts 7, by A '
1The mouth of pipe is discharged and is got back in the atmosphere.Cooling duct as shown be parallel dispersed arrangement and pass the seal bootr housing and seal bootr in cooling space 8, the interior electromagnetic pole space 11 of this space 8 and electromagnetic speed regulator communicates, but is hedged off from the outer world.When electromagnetic pole 12 and 13 high speed rotating, the air A in the enclosure space 8,11
2Via window D
1With D
2Generation circulates.Absorb heat by electromagnetic speed regulator, through D
1Window enters cooling space 8, and the conduit 7 cooling backs (high speed cold air heat absorption in the pipe) that are cooled are passed through D again
2Mouth is got back to speed regulator space 11, enters cooler space 8 after the heat absorption again, and constantly circulation realizes heat exchange, reaches cooling purpose.Because cold wind A by cooling duct
1Do not communicate with cooler seal bootr space, its cooling is to be undertaken by the tube wall conduction of cooling duct, so be called the indirect air cooling type.Cold wind A by cooling duct
1By blast apparatus such as fan produce and by the wind scooper forced guiding by cooling duct, so be called mandatory aeration type again.
Owing to adopted the structure of sealed type and air-cooling apparatus indirectly, the utlity model has following characteristics:
1. electromagnetic speed regulator electromagnetic pole space is hedged off from the outer world, and realizes dustproofly, anticorrosion, life-saving, raises the efficiency, and according to actual needs, can be designed as waterproof and dustproof, anti-corrosion type and explosion-proof type.
2. because cooling device of the present utility model is direct and electromagnetic speed regulator is formed whole, so can become an electric system independently, can reequip the electromagnetic speed regulator of existing electromagnetic varispeed motor, also can design, produce the electromagnetism adjuster that has cooling device separately.
3. simple in structure, cost economic.Because the high speed cold wind of cooling can be taken from the fan of motor itself, also can establish air blast in addition, so be applicable to the electromagnetic speed regulator of large, medium and small type motor.
