Description

Technical Field

[0001] This invention relates to the field of water pump equipment structure technology, and in particular to an integrated electromagnetic induction pump. Background Technology

[0002] Nuclear power plants are equipped with a large number of water pumps, such as reactor pumps, reactor coolant pumps, condensate pumps, high-pressure core overflow pumps, circulating water pumps, seawater pumps, reactor feedwater pumps, and high-pressure core jet pumps. These various types of water pumps serve different functions as power equipment for transportation and are installed in different locations within the nuclear power plant.

[0003] Currently, the aforementioned water pumps can be divided into two categories according to their drive structure. One category is small submersible pumps, which have a two-stage structure, consisting of an AC motor and a water pump connected by a shaft and sealed with a water seal. However, the high-speed rotation of the shaft can easily damage the water seal. When the water seal wears down, water will flow back into the motor windings, causing irreversible damage to the motor. Furthermore, the AC motor operates by attaching the magnetic field of the windings to the rotor, and the rotor's rotation then drives the water pump turbine through the shaft. This method has low operating efficiency and is prone to damaging the water seal and the motor. The other category is large centrifugal pumps, where the pump and motor are driven by a belt or shaft. However, these pumps require a large installation space, and the installation process requires alignment, which is time-consuming and labor-intensive. Moreover, the use of a high-power AC motor to drive a large rotor can cause a large current during instantaneous startup, which can easily affect the system power supply. In addition, when the pump stops, the water hammer effect caused by the sudden interruption of the high-speed water flow can also harm the media system.

[0004] Therefore, there is an urgent need to study an integrated electromagnetic induction pump that requires little installation space, has high safety and high operating efficiency. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] This invention provides an integrated electromagnetic induction pump, see [link to relevant documentation]. Figures 1 to 3 The system includes two stator winding assemblies 1, a turbine assembly 2, and a control circuit. The stator winding assembly 1 includes a stator core 101, with multi-phase coil windings 102 evenly distributed along the circumference of the stator core 101. Two phase coil windings 102 symmetrically arranged with respect to the diameter of the stator core 101 are connected in series on the magnetic circuit, and the two phase coil windings 102 have opposite polarities to form a magnetic pole. The turbine assembly 2 is coaxially disposed between the two stator winding assemblies 1. The turbine assembly 2 includes a turbine body 201 and two rotors 202. The turbine body 201 is coaxially fixedly connected between the two rotors 202. Multiple permanent magnets 203 are evenly distributed along the circumference of the rotors 202. The control circuit is electrically connected to the coil windings 102. The control circuit is used to energize the coil windings 102 to generate an electromagnetic field on the magnetic pole, thereby causing the permanent magnets 203 to drive the turbine body 201 to rotate axially under the action of the electromagnetic field. The control circuit can also control the movement speed of the turbine body 201.

[0036] The electromagnetic induction integrated pump provided by this invention places the turbine assembly 2 between two stator winding assemblies 1, so that the turbine body 201 rotates along with the rotor 202 under the action of the radial magnetic circuit generated by the two stator winding assemblies 1, effectively increasing the area of ​​the thrust action surface. Moreover, the larger the diameter of the turbine body 201, the higher the efficiency of the magnetic force. At the same time, the turbine body 201 is subjected to radial forces on both sides, eliminating the need to rely on the rotation of the shaft to drive the turbine body 201, which greatly saves electrical energy. The two radial magnetic circuits act directly on the turbine body 201, which avoids the complex operations such as multiple mechanical connections and alignment work caused by using a single motor drive, and also saves the use of installation space. Overall, it saves working space, simplifies the operation steps, and improves the operation efficiency. The rotation speed of the turbine body 201 can be adjusted arbitrarily within a certain range by using a control circuit, thereby stabilizing the flow rate and avoiding the impact on the power system and the mechanical impact on the turbine body 201 caused by instantaneous high current operation, thus improving the safety of operation.

[0037] Specifically, in the above embodiments, see Figure 1 The electromagnetic induction integrated pump also includes a pump body 3, which includes a first pump chamber 301, a second pump chamber 302, and a third pump chamber 303 arranged sequentially along the axial direction. A first connecting shaft 304 connects the first pump chamber 301 and the second pump chamber 302, and a second connecting shaft 305 connects the second pump chamber 302 and the third pump chamber 303. A stator winding assembly 1 is disposed in the first pump chamber 301 and is fixedly connected to the first connecting shaft 304. Another stator winding assembly 1 is disposed in the third pump chamber 303 and is fixedly connected to the second connecting shaft 305. A turbine assembly 2 is disposed in the second pump chamber 302, and the two sides of the turbine assembly 2 are rotatably connected to the first connecting shaft 304 and the second connecting shaft 305, respectively. In this embodiment, the pump body 3 includes two support frames, which divide the space inside the pump body 3 axially into three pump chambers. The first pump chamber 301 and the third pump chamber 303, which are used to house the stator winding assembly 1, are of equal size. A connecting shaft is provided on the support frame, with the two ends of each connecting shaft located in two adjacent pump chambers. The stator winding assembly 1 is connected to the connecting shaft in its respective pump chamber, so that the two stator winding assemblies 1 are coaxially fixed in the first pump chamber 301 and the third pump chamber 303, thereby generating a stable magnetic circuit. The turbine assembly 2 is located in the second chamber, and the two ends of the turbine assembly 2 are rotatably connected to the first connecting shaft 304 and the second connecting shaft 305, respectively, ensuring that the turbine assembly 2 is coaxial with the two stator winding assemblies 1. This allows the permanent magnet 203 on the rotor 202 to drive the rotor 202 to rotate axially under the action of the magnetic circuit, while simultaneously driving the turbine body 201 to rotate, achieving the technical effect of this application. Specifically, the pump body 3 is made of high-strength non-magnetic material, and conventionally selected metals other than iron, cobalt, nickel and their alloys and their corresponding alloys are chosen.

[0038] Furthermore, a magnetic field shield 306 is provided on the opening side of both the first pump chamber 301 and the third pump chamber 303. The stator winding assembly 1 is disposed within the magnetic field shield 306, which is made of a magnetically conductive material. In this embodiment, the first pump chamber 301 and the third pump chamber 303 are used to house the stator winding assembly 1. The magnetic field shield 306 is provided on the opening side of the first pump chamber 301 and the third pump chamber 303 to protect the stator winding assembly 1 from accidental impacts or collisions, and to prevent the magnetic field generated by the stator winding assembly 1 from leaking out and affecting other operating equipment, thus creating safety hazards. Specifically, the magnetic field shield 306 is made of a magnetically conductive material, commonly selected from engineering pure iron, magnetically conductive stainless steel, and low-carbon steel. The size of the magnetic field shield 306 can be selected or manufactured according to the size of the stator winding assembly 1, as long as it can completely cover the stator winding assembly 1.

[0039] Specifically, in the above embodiments, see Figure 2 A positioning hole 103 is provided at the center of the stator core 101. The stator winding assembly 1 located in the first pump chamber 301 is connected to the first connecting shaft 304 through the positioning hole 103. The stator winding assembly 1 located in the third pump chamber 303 is connected to the second connecting shaft 305 through the positioning hole 103. The stator core 101 is provided with a plurality of first connecting holes 104 evenly distributed along the circumference. The two stator winding assemblies 1 are fixedly connected to the inner wall of the first pump chamber 301 and the inner wall of the third pump chamber 303 through the plurality of first connecting holes 104 respectively. In this embodiment, the stator winding assembly 1 is connected to two connecting shafts respectively through positioning holes 103 at the center of each stator core 101, facilitating quick positioning and installation of the stator winding assembly 1 and ensuring that the two stator winding assemblies 1 are coaxially arranged. Simultaneously, the stator winding assembly 1 is fixedly connected to the inner wall of the pump cavity through first connecting holes 104. Specifically, the first connecting holes 104 are located between adjacent two-phase coil windings 102. Multiple evenly distributed first connecting holes 104 can stably fix the stator winding assembly 1 and form a stable magnetic circuit, while also facilitating installation and disassembly. The first connecting holes 104 can be selected in various forms, corresponding to multiple fixing methods for the stator winding assembly 1. When the first connecting hole 104 is a through hole, it can be fixed by a pin engaging with the hole; when the first connecting hole 104 is a threaded hole, it can be fixed by a threaded connection. The fixing method is flexible and can be selected according to requirements.

[0040] Specifically, in the above embodiments, see Figure 3Bearing grooves 204 are provided at the center of both sides of the turbine assembly 2, and bearings 205 are disposed in the bearing grooves 204. The bearings 205 near the first pump chamber 301 are sleeved on the first connecting shaft 304, and the bearings 205 near the third pump chamber 303 are sleeved on the second connecting shaft 305. The turbine body 201 rotates circumferentially along the axis between the first connecting shaft 304 and the second connecting shaft 305. In this embodiment, since the turbine assembly 2 is rotatably connected to the first connecting shaft 304 and the second connecting shaft 305 respectively during pump operation, and continuously rotates along the axial direction of the two connecting shafts, bearing grooves 204 are provided on both sides of the turbine assembly 2, and bearings 205 are disposed in the bearing grooves 204 so that the bearings 205 are respectively sleeved on the two connecting shafts. On the one hand, the bearings 205 support the turbine assembly 2, and on the other hand, reduce the coefficient of friction of the turbine assembly 2 during operation, ensuring the rotational accuracy of the turbine assembly 2. The type and model of the bearings 205 can be further selected according to the size of the turbine body 201.

[0041] Specifically, in the above embodiment, the rotor 202 is provided with a plurality of second connecting holes 206 evenly distributed along the circumference, and the two rotors 202 are fixedly connected to the turbine body 201 through the plurality of second connecting holes 206. In this embodiment, the rotor 202 is provided with a plurality of permanent magnets 203. The permanent magnets 203 rotate continuously in the magnetic circuit formed after the stator winding assembly 1 is energized, due to electromagnetic induction, thereby driving the turbine body 201 to rotate to achieve the technical effect of this application. Therefore, the turbine body 201 and the two rotors 202 need to be fixedly connected. Specifically, a second connecting hole 206 is provided between two adjacent permanent magnets 203 on the rotor 202. The rotor 202 and the turbine body 201 are fixedly connected through the second connecting hole 206, so that the turbine body 201 rotates synchronously with the rotation of the rotor 202. Specifically, the form and fixing form of the second connecting hole 206 can be referred to the connection method of the first connecting hole 104, and can be selected according to the requirements.

[0042] Specifically, in the above embodiment, the number of permanent magnets 203 is equal to the number of coil windings 102. Two permanent magnets 203 symmetrically arranged along the diameter of the rotor 202 have opposite polarities. The permanent magnets 203 are either built-in permanent magnets 203 or surface-mounted permanent magnets 203. In this embodiment, the permanent magnets 203 arranged opposite to each other along the diameter of the rotor 202 have opposite polarities, thereby enabling the rotor 202 to rotate in the magnetic circuit formed between the two stator winding assemblies 1. Specifically, the permanent magnets 203 have different connection methods. When the permanent magnets 203 are built-in permanent magnets 203, multiple placement slots are evenly distributed along the circumferential direction of the rotor 202, and the built-in permanent magnets 203 are placed one by one in the placement slots. When the permanent magnets 203 are surface-mounted permanent magnets 203, multiple surface-mounted permanent magnets 203 are attached along the circumference of the rotor 202. The number of permanent magnets 203 can be set to be equal to the number of coil windings 102, so that the rotor 202 can rotate stably in the magnetic circuit.

[0043] Specifically, in the above embodiments, see Figure 4 The control circuit includes a transformer T1 and a processor IC1. The primary side of the transformer T1 is electrically connected to the power supply through a circuit breaker QF. The secondary side of the transformer T1 is electrically connected to the first terminal of the processor IC1 through a rectifier module D1. The second terminal of the processor IC1 is electrically connected to a potentiometer RX. The third terminal of the processor IC1 includes multiple branches equal to the number of magnetic poles. Each branch is electrically connected to the base of the power output transistor Q. The collector of the power output transistor Q is electrically connected to the first terminal of the processor IC1. The emitter of the power output transistor Q is electrically connected to a two-phase coil winding 102 connected in series on a magnetic pole, and then electrically connected to the first terminal of the processor IC1. In this embodiment, the processor IC1 includes multiple pins. Two pins at the first end of the processor IC1 are electrically connected to a power supply to provide power to the processor IC1. Two pins at the second end of the processor IC1 are electrically connected to a potentiometer RX, which is used to control the rotation speed. When the circuit is running, the potentiometer RX sends a signal to the processor IC1 to change the rotation speed, thereby controlling the rotation speed of the turbine body 201. The third end of the processor IC1 is connected to multiple pins, each pin leading out a branch. The number of pins and branches is equal to the number of magnetic poles on the stator core 101. Each branch is also connected to a current-limiting resistor R, which is electrically connected to the base of the power output transistor Q. The emitter of the power output transistor Q is connected in series with two-phase coil windings 102 on the same magnetic pole. The power output transistor Q is used to output current to the coil windings 102, thereby causing each magnetic pole to generate magnetic force. A stable magnetic circuit is generated between the two opposing stator winding assemblies 1, driving the turbine body 201 to rotate.

[0044] Furthermore, the rectifier module D1 can be a single-phase rectifier bridge or a multi-phase rectifier bridge. In this embodiment, the function of the rectifier module D1 is to convert AC power to DC power. Specifically, a single-phase rectifier bridge uses a set of rectifier devices to convert one phase of a three-phase AC power supply to DC power, and is typically used in 220V AC power in urban areas. A multi-phase rectifier bridge is usually a three-phase rectifier bridge, which uses three sets of rectifier devices to convert each phase of a three-phase AC power supply to DC power, and is typically used in industrial power supply with a three-phase input of 380V AC power. The specific form of the rectifier module D1 can be further selected according to the application environment.

[0045] Specifically, in the above embodiment, the primary side of transformer T1 is electrically connected to the power supply through a first fuse FU1. A second fuse FU2 is connected in series with the first terminal of rectifier module D1 and processor IC1, and a filter capacitor C1 is connected in parallel with the first terminal of rectifier module D1 and processor IC1. In this embodiment, the two fuses are respectively set at the output terminal of circuit breaker QF and the output terminal of rectifier module D1. When the current exceeds a specified value, the fuses are melted by the heat generated by themselves, thus disconnecting the circuit and providing protection. The filter capacitor C1 is connected in parallel with the output terminal of rectifier module D1 to filter out the AC component in the current, making the output DC smoother, thus playing a filtering role. Specifically, the filter capacitor C1 is a high-voltage electrolytic capacitor.

[0046] The specific working process of the electromagnetic induction integrated pump provided in this application is as follows:

[0047] 1. Assemble the mechanical structure of the electromagnetic induction integrated pump and connect the two coil windings 102 that are oppositely arranged on the stator core 101 in series;

[0048] 2. The external AC power supply is connected to the control circuit through the circuit breaker QF. When the circuit breaker QF is closed, the power supply passes through the closed circuit breaker QF, then through the first fuse FU1, and then through the transformer T1 to the rectifier module D1 for rectification. After that, it passes through the second fuse FU2 and the filter capacitor C1 for filtering before being supplied to the processor IC1. While the positive power supply supplies power to the processor IC1, it is also supplied to the collectors of multiple power output transistors Q at the third terminal of the processor IC1. The electromagnetic induction integrated pump is in a standby state.

[0049] 3. Slowly adjust potentiometer RX and processor IC1. Multiple pins of the third terminal of processor IC1 output multiple pulse voltages of the first cycle in sequence. The pulse voltages are sent to the base of power output transistor Q in sequence through current limiting resistor R. After receiving the pulse voltage, power output transistor Q is turned on in sequence. The positive power supply is applied to each coil winding 102 in sequence after passing through multiple power output transistors Q, thereby generating an electromagnetic field in sequence, which acts on each permanent magnet 203 on rotor 202. Since all coil windings 102 are in a fixed state, the permanent magnets 203 cause the turbine body 201 to move in a circular motion under the relative action of the electromagnetic field. When the control circuit completes one cycle of operation, the first operating cycle of turbine body 201 is completed.

[0050] IV. If the potentiometer RX remains in its current state, multiple pulse voltages will be output cyclically according to the current cycle time to ensure that the turbine body 201 operates at a stable speed. If the speed potentiometer RX is adjusted, the pulse voltage cycle period is compressed, the time to complete one cycle is shortened, and the turbine body 201 rotates faster and faster under the action of the electromagnetic field until the set maximum speed is reached.

[0051] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
