Abstract
The utility model relates to a submersible motor's is sealed, is particularly suitable for deep well submersible motor's preparation and work at high temperature, leans on the water-cooled environment.
The utility model discloses outside the housing shield, the motor housing inside, above the bush, add rubber "O" shape circle below the clamp plate, lean on fastening force between bush and the clamp plate, make rubber "O" shape circle expand outward, and form rubber "O" shape circle, and seal with housing shield, motor housing to reach in water can not invade motor winding.
Description
The utility model relates to the sealing of submersible motor, is particularly suitable for the making of deep-well submersible motor, and is operated in high temperature, by the environment of water-cooled.
Common submersible motor is to prevent in the water intrusion motor windings by the mechanical seal of sound; The submersible motor that also has adopts nylon sheathed wire and realizes insulating requirements, and the latter is insulated into the degree height.But the electromagnetic wire external diameter is thick, and the electric machine iron core utilance is low.
In order to solve the mechanical seal deep diving, the problem that the nylon sheathed wire iron core utilization is low.The utility model adopts static seal, in " eelctrical engineering handbook " relevant for the narration of mechanical seal.The utility model uses housing, but on the material, the new mode of its difference arranged on the hermetically-sealed construction.
The purpose of this utility model will provide a kind of improved sealing device exactly, and it can prevent the water intrusion motor windings effectively.
The utility model purpose is such, adds rubber " O " type circle at motor internal, metallic shield cover, lining, pressing plate, securing member and form static seal device.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is according to the profile that the utility model proposes sealing device.
Describe details and working condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.
Sealing device of the present utility model, comprise a motor housing (1), in shell the inside a motor windings (5) is arranged, a lining (2), a pressing plate (3), the rubber of two different-diameters " O " type circle (4), a housing (6) that forms with metallic plate punching press of 0.1-1 millimeter or metallic plate shaping, six securing members (7) (8), it is fastening with pressing plate (3) and lining (2) to be close to firmware (7) (8), make rubber " O " type circle (4) distortion outer bloated, and form rubber " O " type circle (4) and housing (2), motor housing (1) sealing can not be invaded in the motor windings (5) thereby reach water.Another method also can reach the waterproof purpose: with pressing plate (3), and stator casing (1) thread cutting, turn pressing plate (3), and compress rubber " O " type circle (4).Though a kind of method in back is simple, also in full force and effect.
Claims (3)
1, a kind of submersible motor sealing device, it is characterized in that hermetic unit has a motor housing (1), rubber " O " the type circle (4) that (2) two different-diameters of a lining are arranged, lining (2) adjacency has a pressing plate (3), lining (2) is fastening with pressing plate (3), and stator interior is put into metal lining (6).
2, according to the described device of claim 1., it is characterized in that stator interior adds metal lining (6), adopt 0.1 to 1 millimeter metallic plate, punching press or metallic plate integer form.
3,, it is characterized in that lining (2) and pressing plate (3) is fastening is close to firmware (7), (8), or pressured plate (3), the gas thread of thread cutting and stator casing (1) car system and compressing according to the described device of claim 1..
