Abstract
A submersible motor protector consists of an intermediate flange, a supporting body, a rotating shaft, an upper cover and a sand slinger, wherein one end of the intermediate flange is connected with the motor via a sealing element, the other end is connected with the supporting body via the sealing element, and the upper end of the supporting body is connected with the upper cover via a sealing device; one end of the rotating shaft is connected with a motor shaft via a shaft coupling, the other end is connected with the connecting end of a pump via the shaft coupling, and the rotating shaft positioned at the outer end of the upper cover of the supporting body is provided with the sand slinger. The advantages and technical effects of the utility model lie in that the problem of reliability of the full-water (wet-type) submersible motor, under the bad conditions such as seawater, brine, high sand content and high corrosion, etc., is solved, which greatly enhances the life span of the full-water (wet-type) submersible motor, and extends the application fields of the full-water (wet-type) submersible motor.
Description
The utility model relates to motor device, particularly a kind of submersible motor protector.
At present, Water subduction motor adopts the movable sealing structure of single track mechanical seal or double-deck oil sealing, this structure subduction motor contains in sand or the corrosive liquids at height, the useful life of mechanical seal or oil sealing is extremely low, the inefficacy of its function will cause reduce the useful life of motor, thus the life-span of reducing whole system.
The purpose of this utility model is to provide a kind of submersible motor protector, and it can solve the seal defect problem of above-mentioned subduction motor, is a kind of novel submerged motor protective device.
The technical solution of the utility model: a kind of submersible motor protector is characterized in that it is made of counter flange, supporting mass, rotating shaft, loam cake and sand-throwing ring; Said counter flange is made of ring flange and counter flange seal; Said supporting mass is a seal chamber structure, is made of supporting base and supporting mass bearing shell; Said rotating shaft is made of axle sleeve, axle and sealing device; Said loam cake reaches upward by lid, and cap sealing constitutes; Said counter flange one end is connected with motor according to the counter flange seal, and the other end is connected with supporting mass according to the counter flange seal, and the supporting mass upper end is connected with loam cake according to last cap sealing; Said rotating shaft one end connects motor shaft according to shaft coupling, the rotating shaft axle sleeve and the supporting mass bearing shell that are a pair of fastness form place on the supporting base of supporting mass, there is sealing device loam cake the inner of supporting mass, the rotating shaft other end is equipped with sand-throwing ring according to the link of shaft coupling connection pump in the loam cake outer end rotating shaft of supporting mass.
End sealing device can be mechanical seal, oil sealing, helixseal or its combined sealing structure in the above-mentioned said loam cake.
Above-mentioned said mechanical seal can comprise stationary ring, rotating ring and spacer.
Above-mentioned covering on said can be equipped with overflow valve and sealing ring.
Above-mentioned said flange seal spare can comprise cover type nut, studs, packing ring, round section joint ring and Sealed Observation Window.
Above-mentioned said shaft coupling can adopt telescopic, castellated or spline.
Operation principle of the present utility model: this protector top connects pump, the following motor that connects, sand or corrosive liquids are at first thrown bigger solid particle out through sand-throwing ring when electric pump is worked, remainder particle and liquid will enter the sealing device of protector loam cake along axle, because the desirable helixseal of sealing device, when helixseal when being left-handed, and the motor direction of rotation is counterclockwise, so just form pressure reduction at the loam cake two ends, liquid is flowed from inside to outside, guarantee that solid particle and corrosive liquids do not enter the protector inner chamber; The helixseal back uses mechanical seal to guarantee the sealing effectiveness of protector supporting mass.Owing to adopt cavity body structure in the supporting mass, when above-mentioned sealing device inefficacy or partial failure, solid particle with after corrosive liquids enters cavity since density different make density greater than the solid particle of water and liquid natural subsidence to cavity bottom, have only when deposit surpasses supporting mass supporting base height, these materials just might enter counter flange through the bearing clearance, just can enter motor cavity by the mechanical seal on the motor top guide bearing again.
Superiority of the present utility model and technique effect are thoroughly to solve water-filling (wet type) submergence type motor, at seawater, bittern and the high integrity problem that contains the abominable place of environment such as sand, high corrosion, improve water-filling (wet type) submergence type motor useful life greatly, and expanded water-filling (wet type) submergence type motor and used the field.
