Description
Technical field
The invention belongs to deep-well pump technical fields, are related to a kind of sensor fixing structure of deep-well pump motor.
Background technique
The maximum feature of deep well pump is that one is made in motor and pump, it be immerse underground water well in carry out suction and it is defeated
A kind of pump for sending water, is widely used in farmland discharging-irrigating, industrial and mining enterprises, urban water supply and sewerage and sewage treatment etc..Deep well pump at present
The wheel rotation being generally used in ordinary motor transfer tube, common deep well pump are difficult to play the benefit of impeller.In the prior art,
Converter plant can be generally equipped with and improve motor speed, if Authorization Notice No. is one kind disclosed in CN 202334162U Chinese patent
The frequency conversion device mounting structure of immersible pump.
But with the development that deep well pump is applied, more stringent requirements are proposed to its performance by people, and determining deep well pump makes
It is exactly the performance of motor with the most important factor of performance.In recent years, a kind of New-type electric machine, i.e. switched reluctance machines are gradually come into
Market.Its due to electric machine structure it is simple, it is at low cost, can be used for running at high speed, power circuit is simple and reliable, system reliability is high,
Starting torque is big, starting current is low, be suitable for frequent start-stop and forward and reverse conversion operation is high-efficient, small, good speed adjustment features are lost
The advantages that, existing deep-well pump motor can be substituted, well to improve deep well pump performance.
Switched reluctance motor is mainly by switched reluctance motor, power inverter, controller, rotor position detector four
Most of composition.Wherein, the position sensor of Hall element and rotor magnetic ring composition is rotor common in switched reluctance machines
Position detection unit.Specifically, magnet ring is made of one or more groups of N/S magnetic poles, magnet ring and rotor be fixedly connected and with
Rotor synchronous rotary, the magnet ring N/S pole field variable signal energy real time reaction that Hall element detects go out rotor present bit
It sets, controller determines the ON/OFF strategy of current motor winding according to collected rotor position information.And machine winding
The location point of ON/OFF will affect motor operation efficiency, and advanced or lag can all influence system performance, deposit to certain operating conditions
In an optimum position point, make motor delivery efficiency highest.In order to determine this optimum position point, need micro- whole Hall element and
System best efficiency point is found out in the relative position of magnet ring.That is, in order to make the deep well pump produced reach optimum operation
Can, best efficiency point is found out then just needing to make debugging repeatedly to the installation site of Hall element when manufacturing assembling；Meanwhile
Since the position of Hall element determines last testing result, the accuracy of the last installation site of Hall element
It is most important, as long as there is a deviation just to will affect motor performance.
In the prior art, conventional technology is that Hall member is realized in the general cooperation by design adjustment hole and bolt
The adjusting and installation of part.As Chinese patent [application number: 201520517163.7] discloses a kind of patch hall position sensing knot
Structure, including the fixation holder assembly for being mounted in shaft and the Hall subassembly for being mounted on rear end cap；Fixation therein
Holder assembly includes fixing seat and magnet ring, and Hall subassembly includes Hall Plate and patch Hall.Hall subassembly therein is to pass through kidney-shaped
Locking for the fitted bolt of slot and bolt is covered in motor rear end.Although in above-mentioned sensing arrangement, Hall subassembly position tune
Section gets up more convenient, but the matching area of kidney slot and bolt is limited after all, and the position positioning of Hall subassembly completely according to
It is positioned by bolt, then it is inevitable during bolt screws when above-mentioned Hall subassembly is determined eventually by debugging position
It will appear displacement, will lead to the installation site inaccuracy of final Hall subassembly in this way, influence motor performance.It is above-mentioned in order to make up
Defect, technological means commonly used in the prior art are often to be guaranteed using increasing bolt quantity or increasing the quantity of adjustment hole
The accurate installation of final Hall subassembly position.
Summary of the invention
The purpose of the present invention is there is the above problem in view of the prior art, a kind of sensor of deep-well pump motor is proposed
Mounting structure, present invention solves the technical problem that being how to make position of the Hall subassembly in debugging easy to adjust and final installation
Position is accurate.
Object of the invention can be realized by the following technical scheme: a kind of sensor fixing structure of deep-well pump motor,
The motor includes bearing block, magnet ring and Hall subassembly positioned at bearing block one end, and the sensor fixing structure includes being used for
The Hall support installing Hall subassembly and being set on the outside of magnet ring, which is characterized in that be equipped with and match between the Hall support and magnet ring
Benchmark is closed, the cooperation benchmark, which carries out limit to Hall support in a manner of stopping, enables Hall support with the magnet ring axle center
Centered on make Circular Sliding, between the Hall support and bearing block be equipped with locking structure, when the Hall support passes through circular arc
Sliding is connected on bearing block after adjusting the position of Hall subassembly by the locking structure.
When Hall subassembly, which needs to debug, finds best position, since Hall support is connected in by locking structure
On bearing block, need first to release the locking relation of the two, then the relative position to Hall subassembly in magnet ring circumferential direction carries out micro-
Adjust, be different from the prior art, the sensor fixing structure of this deep-well pump motor by designed between Hall support and magnet ring with
Upper cooperation benchmark enables Hall support with the magnet ring axis since cooperation benchmark carries out limit to Hall support in a manner of stopping
Make Circular Sliding centered on the heart, under the guiding role of cooperation benchmark, then need to only make Hall support walking along cooperation benchmark
It can be realized as adjustment of the Hall subassembly with respect to magnet ring circumferential position to sliding, so that position of the Hall subassembly in debugging
It adjusts very convenient；Simultaneously as cooperation benchmark can be Hall branch always in the position adjustment of above-mentioned Hall subassembly
Frame provides reliable limit, so that Hall support will not be not only displaced during position adjusts, and in position
After determination, due to cooperating the position-limiting action of benchmark, in this way when Hall support is connected on bearing block again through locking structure,
Its position is also less likely to occur offset change in locking process, to guarantee that the final installation site of Hall subassembly is accurate；And
And when Hall support is assembled on bearing block, cooperation benchmark can also be determined for the installation site of Hall support and be provided accurately
Positioning also ensures its subsequent fine position and the accuracy that position determines in this way；That is, by designing above, on
State cooperation benchmark both played Hall support during installation, debugging when positioning, position-limiting action, and play position adjust when
Guiding role while can also guarantee its final installation site so that position is easy to adjust when Hall subassembly is debugged
Shift variance will not occur in fixation procedure in accuracy, so that motor can be operated with optimal performance to improve depth
