Specific embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of boosting water injector of screw pump, including motor 4, screw pump 16, the motor 4 is electrically connected by terminal box 2 and cable 3 with the device controller in control cabinet 1, and motor 4 passes through flexibility Attachment device is connect with screw pump 16, and positive and negative two thrust bearings 5,6 or one are provided on the motor shaft 7 of the motor 4 Two-direction thrust bearing, mechanical seal 12 are mounted on motor shaft 7, which is characterized in that pressure balance dress is provided in gas-tight silo 8 It sets.
The flexible connecting device can be shaft coupling and add flexible link, be also possible to one of universal joint, shaft coupling etc., Those skilled in the art understand that the motor shaft 7 of motor is unable to rigid connection screw pump 16, but can be by above-mentioned Various ways solve the problems, such as the two flexible connection, and the embodiment of the present invention and schematic diagram are with shaft coupling 13 and 15 groups of flexible link At flexible connecting device.
Positive and negative two thrust bearings are provided in the motor 4, when equipment is inactive, water inlet 14 is intake, and is just had and Water pressure compressing, motor shaft 7 will receive downward axial force, and thrust bearing 26 undertakes the axial force, after equipment operates normally, 16 outlet pressure of screw pump is greater than water inlet pressure, and rotor can generate upward axial force, and be transferred to flexible link 15 and motor Axis 7, thrust bearing 1 transmit the axial force come up when undertaking equipment work.
One thrust bearing is respectively installed up and down in motor shaft, it is contrary, it is therefore an objective to motor shaft axially play is prevented, Motor shaft is solved sometimes by downward pulling force, sometimes by upward thrust, causes to generate excessive displacement, to make mechanical close 12 failure of envelope, therefore, positive and negative two thrust bearings can also be replaced with a two-direction thrust bearing, be acted on and positive and negative two Thrust bearing is identical, and those skilled in the art are understood that completely and install according to the actual situation.
As shown in Fig. 2, the pressure equaliser can be spiral elongated tubular 17, one end and sealed inner tube 11 are fixed It connects, is provided with through-hole on sealed inner tube 11, the dynamo oil in motor 4 enters spiral elongated tubular 17 by above-mentioned through-hole, another End is fixedly connected with sealed base 10, through-hole is also provided on sealed base 10, water enters spiral shell by the through-hole on sealed base 10 Elongated tubular 17 is revolved, the both ends of spiral elongated tubular 17 are logical with dynamo oil and water phase respectively.In this way, forming water in spiral elongated tubular 17 With the pressure balance of oil.Lighter than water because the specific gravity of dynamo oil is about 0.8, the two will form lamination, and oil water contact Face is in sealing pipeline 11, and when dynamo oil expands with heat and contract with cold, contact surface floats up and down in pipeline, and the volume of pipeline will meet electricity Dilation amount under machine oil work, prevents water from entering in motor, and dynamo oil and water inlet 14 is made to carry out hydraulic pressure in this way Dynamic balance can work normally mechanical seal 12, and medium will not be sufficiently mixed again, make to be insulation always in motor Dynamo oil can work normally equipment, and high-pressure rotary mechanical seal 12 is achieved, and protect engine 4 at work.It needs Illustrate: the structural pressure balanced structure of this spiral elongated tubular 17 can be used in vertical screw pump boosting water injector, It cannot be used in horizontal screw pump boosting water injector.
As shown in figure 3, the pressure equaliser can be serpentine channel, it is more than two heavy to install additional in gas-tight silo 8 Drop pipe, sedimentation pipe 1 are fixedly connected with gas-tight silo 8, and sedimentation pipe 2 19 is fixedly connected with sealed base 10, is made between sedimentation pipe Closed motor oil liquid serpentine channel is formed, serpentine channel one end is fixedly connected with sealed inner tube 11, is provided on sealed inner tube 11 Through-hole, the dynamo oil in motor 4 enter serpentine channel by above-mentioned through-hole, and the other end is fixedly connected with sealed base 10, close Also through-hole is provided on back cover seat 10, water enters serpentine channel, the both ends difference of serpentine channel by the through-hole on sealed base 10 It is logical with dynamo oil and water phase.Dynamo oil and water form pressure balance in serpentine path.The diameter of the sedimentation pipe can be identical It can also be different.It is lighter than water because the specific gravity of dynamo oil is about 0.8, it will form lamination, and oil water boundary is settling Intracavitary, when dynamo oil expands with heat and contract with cold, oil water boundary floats up and down in sedimentation chamber, and the volume of sedimentation chamber will meet dynamo oil Dilation amount under work, prevents water from entering in motor, so that dynamo oil and water inlet 14 is carried out water pressure in this way flat Weighing apparatus, can work normally mechanical seal 12, protect engine 4.It should be understood that the structural pressure of this serpentine channel is flat The structure that weighs can be used in vertical screw pump boosting water injector, it is impossible to be used in horizontal screw pumps in boosting water injector.
The pressure balancing structure is capsule 20, and the capsule 20 is mounted on sealed inner tube 11, above and below capsule 20 Both ends are closely connect with 11 outer wall of sealed inner tube, and through-hole is provided on sealed inner tube 11, and the dynamo oil in motor 4 passes through above-mentioned logical Hole can enter in capsule 20, through-hole is also provided on sealed base 10, water enters capsule 20 by the through-hole on sealed base 10 Dynamo oil and water is isolated in outside, capsule 20.Since dynamo oil and water is isolated in capsule, prevent water from entering motor, while capsule in this way It is flexible material production, can stretches, meet expanding with heat and contract with cold for dynamo oil, moreover it is possible to balance two sides fluid pressure, pass through this side Formula makes dynamo oil and 14 water pressure balance of water inlet, can work normally mechanical seal 10, protects motor 4.It needs Bright: this 20 formula pressure balancing structure of capsule can be used in vertical screw pump boosting water injector, can be used for crouching In formula screw pump type pressurizing water injection device.
Preferably, the motor is permanent magnet synchronous motor, and permanent magnetic synchronous motor structure is simple and durable, and it is big to be able to achieve the slow-speed of revolution Torque output, the non-inductive current excitation of rotor, power factor reaches 0.9 or more, thus improve the quality of power grid because Number, reduces and eliminates the compensation equipment in corresponding power grid, reduce cost of investment, simplify electric network composition, convenient for management.
Preferably, the controller in control cabinet 1 is realized to the current feedback of permanent magnet synchronous motor 3, velocity feedback and position The Three-loop control of feedback, the accurate speed and torque for controlling motor, flexible smooth driving motor substantially reduce system loss, Realize that whole system overall efficiency maximizes operation.
Preferably, GPRS remote control module can be equipped on the controller of control cabinet 1, can by equipment operating data and The data such as disengaging water pressure pass to server and backstage, and realization is monitored and controlled in real time in Visualization Platform, are not necessarily to execute-in-place The orderly progress of entire water filling link can be realized.
