Description
Technical field
The present invention relates to a kind of water conservancy machinery, and in particular to a kind of motor of the submersible pump for drawing water.
Background technology
Submersible pump is the conventional equipment such as field irrigation, water drainage, fish pond water supply and sewage, with using spy wide, that amount is big
Point.Submersible motor is the power section of submersible pump, and submersible pump sealing is generally divided into electrically sealing and bearing seal two parts.
On Wet submersible motor, this two parts sealing solves to compare successfully, and the country has many immersible pump factories just single to produce
Wet submersible motor matching pump section. the electric sealing of Wet submersible motor and bearing seal are each independent, such as bearing seal failure,
Only cause the rolling bearing water inlet that water enters sand, oils and fatss or thin oil lubricant that lubricates of water lubriucated bearing, consequence is accelerated wear test and rust
Erosion, as long as motor is not short-circuit can operate as usual.
But at present its bearing adopts the sealing means of outside framework oil seal, sealing effectiveness is poor, and water is easily by outside framework oil seal and axle
Between enter bearing chamber, after mix with the grease in bearing room impact bearing service life.
The content of the invention

The rotor set dress is arranged in motor, and the stator assembling is arranged on rotor assembling outside；The inlet segment is arranged on
The motor top, the upper bearing (metal) is arranged on inlet segment lower section, and the lower bearing is arranged on the motor bottom；
First mechanical seal is installed in the middle part of the inlet segment；Is provided with the top chock bottom of the upper bearing (metal)
Two mechanical seals；The 3rd mechanical seal is installed on the top chock top of the lower bearing.
The installation of first mechanical seal, the second mechanical seal and the 3rd mechanical seal is specific as follows：
A. respectively in the middle and lower part position setting mechanical seal on the top of step, the bottom of top chock and inlet segment
Stationary seat；
B. rotor assembling with the position that is engaged of sealing to be mounted make corresponding axle according to the requirement of mechanical seal
Footpath, step or location hole；
C. each mechanical seal is installed, dynamic sealing is formed in the top and the bottom of the top of lower bearing and upper bearing (metal) respectively.
Beneficial effect：It is close that the present invention arranges machinery by the two ends of the upper bearing (metal) in submersible motor and the upper end of lower bearing
Envelope, can effectively prevent water from entering bearing chamber, and bearing runs the service life that can effectively extend bearing in water-free lubrication fat.

Wherein, 1 is inlet segment, and 2 is the first mechanical seal, and 3 is top chock, and 4 is upper bearing (metal), and 5 is the second mechanical seal,
6 is motor casing, and 7 is stator assembling, and 8 is rotor assembling, and 9 is the 3rd mechanical seal, and 10 is step, and 11 is lower bearing, 12
For bearing cap.
Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the concrete structure schematic diagram of the present invention.As shown in figure 1, the Mechanical Sealed Type submersible motor of the present invention includes
Rotor assembling 8, stator assembling 7, motor casing 6 and metal (upper.Rotor assembling 8 is arranged in motor, and stator assembling 7 is arranged on
The outside of rotor assembling 8, outermost is assembled by motor casing 6, forms an entirety.
Motor top is provided with inlet segment 1, upper bearing (metal) 4 is installed below inlet segment 1, in the case where motor bottom is installed
Bearing 11.Metal (upper is sealed to whole motor jointly, prevents water from entering motor internal, and whole motor is impacted.
The structure of the bottom of lower bearing 11 keeps constant.It is a kind of static seal, and by bearing cap 12, sealing ring lower axle is connected to
In bearing 10, the positive sealing of the bottom of lower bearing 11 is constituted, thus water can not enter bearing chamber in position.In the upper of step 10
Portion arranges one mechanical seal, is the 3rd mechanical seal 9.Specific embodiment：A. the 3rd is arranged on the top of step 10
The stationary seat (room) of mechanical seal 9；B. mechanical seal is pressed with the matching part of the 3rd mechanical seal 9 in the bottom of rotor assembling 8
Requirement make the corresponding diameter of axle, step or location hole etc.；C. install and the dynamic of the top of lower bearing 11 is formed after the 3rd mechanical seal 9
Sealing, prevents water here position from entering lower bearing room.
One mechanical seal is set in the bottom of top chock 3, is the second mechanical seal 5.Specific embodiment：A. upper
