In order to make the technical problems, technical solutions and advantageous effects solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and the detailed description. It should be understood that the detailed description and specific examples, while indicating the utility model, are intended for purposes of illustration only and are not intended to limit the scope of the utility model.
Fig. 1 is a sectional view of the overall structure of the present invention after installation.
The labels in the figure are: the pressure regulating device comprises a pressure regulating movable shell 1, a pressure regulating static shell 2, a motor base 3, a motor main body 4, a thread 5, a pressure regulating motor 6, a pressure regulating gear column 7, a pressure regulating gear ring 8, an internal pressure sensor 9, an external pressure sensor 10 and a filter screen 11.
Detailed Description
Combine the attached drawing to show, this embodiment provides an explosion-proof base of latent oil motor, move shell 1 and the quiet shell 2 of pressure regulating including the pressure regulating, the pressure regulating moves shell 1 and the quiet shell 2 of pressure regulating and is the metal material, satisfies explosion-proof demand.
The pressure regulating moves shell 1 and the quiet shell 2 of pressure regulating and all sets up in motor base 3, the quiet shell 2 cooperation of pressure regulating is fixed in motor main part 4 and motor base 3 handing-over department, the lower part of the quiet shell 2 of pressure regulating is passed on the upper portion of pressure regulating moves shell 1, the outer wall of pressure regulating moves shell 1 and the quiet shell 2 bottom screw thread 5 cooperation of pressure regulating, make the pressure regulating move shell 1 can reciprocate along the quiet shell 2 of pressure regulating, be provided with regulating motor 6 on the quiet shell 2 of pressure regulating, connect pressure regulating gear post 7 on regulating motor 6's the rotation axis, the top of pressure regulating moves shell 1 is fixed with pressure regulating gear ring 8, pressure regulating gear post 7 and the cooperation of pressure regulating gear ring 8.
When the output shaft of the pressure regulating motor 6 rotates anticlockwise, the pressure regulating gear ring 8 and the pressure regulating movable shell 1 rotate clockwise, and the pressure regulating movable shell 1 moves downwards relative to the pressure regulating stationary shell 2 through the matching of the pressure regulating movable shell 1 and the thread 5 between the pressure regulating stationary shells 2; when the output shaft of the pressure regulating motor 6 rotates clockwise, the pressure regulating gear ring 8 and the pressure regulating movable shell 1 rotate anticlockwise, the pressure regulating movable shell 1 moves upwards relative to the pressure regulating movable shell 2 through the matching of the pressure regulating movable shell 1 and the thread 5 between the pressure regulating movable shell 2.
The quiet shell of pressure regulating 2 all has the opening and for hollow structure with the top that the shell 1 was moved in the pressure regulating, makes 4 inside and the quiet shell of pressure regulating 2 of submersible motor main part and the inside intercommunication of shell 1 are moved in the pressure regulating, and the quiet shell of pressure regulating 2 and the pressure regulating move the inside oil pressure of shell 1 promptly for the oil pressure in the submersible motor main part 4, and the quiet shell of pressure regulating 2 tops still is provided with filter screen 11, filters the impurity that enters into in the motor main part 4.
An internal pressure sensor 9 is arranged in the motor main body 4 and used for detecting the internal pressure of the motor main body 4; be provided with external pressure sensor 10 in the motor base 3, because motor base 3 is the intercommunication with the outside, therefore the oil in the motor base 3 is the outside oil pressure of motor main part 4 promptly, also is the whole outside oil pressure of oily motor for detect motor main part 4 external pressure, through the pressure differential of contrasting interior pressure sensor 9 and external pressure sensor 10, and then through the corotation or the reversal of control system control regulating motor 6, make the pressure regulating move shell 1 and move up or move down.
And (4) a pressure adjusting mode.
Through the oil pressure that monitoring external pressure sensor 10 and internal pressure sensor 9 detected, when 4 internal pressure of motor main part were higher than external pressure, regulating motor 6 drove 7 anticlockwise rotations of pressure regulating gear post to drive 8 clockwise rotations of pressure regulating gear ring, pressure regulating moves shell 1 and 8 clockwise rotations of pressure regulating gear ring simultaneously, under the quiet shell 2 of pressure regulating moved 1 screw thread 5 mating reaction of shell, 1 downstream of pressure regulating moved shell, until the pressure balance in the motor, 6 stop work of regulating motor.
When motor internal pressure is less than external pressure, pressure regulating motor 6 drives pressure regulating gear post 7 clockwise rotation to drive 8 anticlockwise rotations of pressure regulating gear ring, shell 1 is also anticlockwise rotated in the pressure regulating, and under the static shell 2 of pressure regulating and the 1 screw thread 5 cooperation effect of pressure regulating shell, shell 1 upward movement is moved in the pressure regulating, until the pressure balance in the motor, pressure regulating motor 6 stop work.
