Description
Technical field
The utility model is related to a kind of water conservancy machinery, and in particular to a kind of motor of the submersible pump drawn water.
Background technology
Submersible pump is the conventional equipment such as field irrigation, water drainage, fish pond water supply and sewage, with the spy that use is wide, 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, the sealing of this two parts is solved to compare successfully, and the country has many immersible pump factories just single to produce
The electric sealing and bearing seal of Wet submersible motor matching pump section Wet submersible motors are each independent, such as bearing seal failure,
The lubrication water of water lubriucated bearing is only caused to enter the rolling bearing water inlet of sand, grease or thin oil lubricant, consequence is accelerated wear test and rust
Erosion, can be operated as usual as long as motor is not short-circuit.
But its current bearing uses 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 lubricating grease in bearing chamber influence bearing service life.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the utility model provides a kind of Mechanical Sealed Type and dived
Hydroelectric machine, mechanical seal is set at the two ends of upper bearing (metal) and the upper end of lower bearing,
Technical scheme：
A kind of Mechanical Sealed Type submersible motor, including the assembling of inlet segment, upper bearing (metal), stator, rotor set are filled with and lower bearing；
The rotor set dress is arranged in motor, and the stator assembling is arranged on the rotor and assembles outside；The inlet segment is arranged on
At the top of the motor, the upper bearing (metal) is arranged on below the inlet segment, 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.
Beneficial effect：The utility model sets machinery by the two ends of the upper bearing (metal) in submersible motor and the upper end of lower bearing
Sealing, can effectively prevent water from entering bearing chamber, bearing is run in water-free lubrication fat can effectively extend the service life of bearing.
Brief description of the drawings
Fig. 1 is concrete structure schematic diagram of the present utility model.
Wherein, 1 is inlet segment, and 2 be the first mechanical seal, and 3 be top chock, and 4 be upper bearing (metal), and 5 be the second mechanical seal,
6 be motor casing, and 7 be stator assembling, and 8 be rotor assembling, and 9 be the 3rd mechanical seal, and 10 be step, and 11 be lower bearing, 12
For bearing cap.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 is concrete structure schematic diagram of the present utility model.As shown in figure 1, Mechanical Sealed Type diving of the present utility model
Motor includes rotor assembling 8, stator assembling 7, motor casing 6 and metal (upper.Rotor assembling 8 is arranged in motor, stator pack
Fill 7 and be 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, under motor bottom installation
Bearing 11.Metal (upper is sealed to whole motor jointly, prevents water from entering motor internal, whole motor is impacted.
The structure of the bottom of lower bearing 11 keeps constant.It is a kind of static seal, and lower axle is connected to by bearing cap 12, sealing ring
In bearing 10, the reliable 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 sets one of mechanical seal, is the 3rd mechanical seal 9.Embodiment：A. the 3rd is set on the top of step 10
The stationary seat (room) of mechanical seal 9；B. 8 bottom is assembled in rotor and presses mechanical seal with the matching part of the 3rd mechanical seal 9
Requirement make the corresponding diameter of axle, step or positioning hole etc.；C. install and the dynamic of the top of lower bearing 11 is formed after the 3rd mechanical seal 9
Sealing, prevents that position enters lower bearing room to water herein.
One of mechanical seal is set in the bottom of top chock 3, is the second mechanical seal 5.Embodiment：A. upper
The bottom of bearing block 3 sets the stationary seat (room) of the second mechanical seal 5；B. 8 positions coordinated with the sealing are assembled in rotor to press
The corresponding diameter of axle, step or positioning hole etc. are made in requirement according to mechanical seal；C. install after the second mechanical seal 5, in upper bearing (metal) 4
Bottom formed one of dynamic sealing, prevent water from this position enter upper bearing (metal) room.
Meanwhile, one of mechanical seal is set at the middle part of inlet segment 1, is the first mechanical seal 2.Embodiment：a.
In the middle and lower part position of inlet segment 1, the stationary seat (room) of the first mechanical seal 2 is set；B. 8 and sealing cooperation are assembled in rotor
The corresponding diameter of axle, step or positioning hole etc. are made by the requirement of mechanical seal in position；C. install after the first mechanical seal 2 upper
One of dynamic sealing is formed at the top of bearing 4, prevents water from entering upper bearing (metal) room from this position.
The upper and lower parts of upper and lower bearing can effectively prevent water from entering bearing chamber after all implementing quiet (dynamic) sealing, and bearing exists
Operation can effectively extend the service life of bearing in water-free lubrication fat.
Described above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art
