Surely link together, so, the cooling air-flow blown out through cooling fan 3 is cooled down by convection current to variable-frequency governor 2.
Cooling fan 3 includes impeller, and impeller includes wheel hub 31 and some flabellums 32 extended to external radiation from wheel hub 31,
The direction of rotation when incline direction of flabellum 32 runs with cooling fan 3 is conversely, the flabellum 32 of the cooling fan 3 uses hypsokinesis
The structure type of formula, such structure design can reduce the operating noise of cooling fan 3.
The cooling fan 3 is independently driven by the variable-frequency motor in the fan guard of permasyn morot 1, because
This, no matter variable-frequency governor 2 drives permasyn morot 1 runs under which kind of rotating speed rotating speed, the cooling gas of the cooling fan 3
Stream parameter can keep constant.In the present embodiment, cooling air-flow parameter is:Air quantity 337m3/h, blast 35Pa.
The cooling device operationally, sprays damping fluid on the inwall of flabellum 32 and fan guard, so, can reduce cold
But the vibration in the process of running of fan 3.
In order to strengthen radiating effect, support 11 and base plate 21 are made by aluminum material, and support 11 is in addition to upper surface
Radiating ribs 113 are equipped with other end faces, the bearing of trend of radiating ribs 113 is perpendicular with the end face for setting the radiating ribs 113.Bottom
Radiating ribs 213 also are provided with plate 21.
Variable-frequency governor 2 also includes casing and the inverter being arranged in casing, because the caloric value of inverter is larger, will
Inverter is arranged on the connecting portion 212 of base plate 21.
Because water pump is loaded with moistureproof requirement, so the shell of variable-frequency governor 2 is provided with sealing structure, this is in certain journey
The radiating effect of variable-frequency governor 2 is have impact on degree, therefore, the capacity of the power tube of the inverter will be in the standard of same specification
Moderately amplify on the basis of the capacity of the power tube of inverter, and the power tube of inverter is arranged on base plate 21, with
It is easy to the heat loss through conduction of power tube.
Variable-frequency governor 2 also includes the AC reactor of the capable AC side for being arranged on variable-frequency governor 2 and is arranged on change
Direct current reactor on the output end dc bus of frequency speed regulator 2, so, can on the spot absorb the higher hamonic wave of inverter generation,
The electromagnetic noise of variable-frequency governor 2 is reduced, so that the noise reduction of feedwater pump assembly.
Heat-insulating and shock-absorbing device 4 is provided between the connecting portion of permasyn morot 1 and variable-frequency governor 2, by every
The setting of hot damper 4, the heat that can prevent the machine of permasyn morot 1 from carrying on the back is transmitted to frequency control by support platform 111
Device 2, while the vibration that can also reduce permasyn morot 1 in operation is delivered to variable-frequency governor 2.
As illustrated, heat-insulating and shock-absorbing device 4 includes main body 41 and be embedded to be embedded portion 42 in main body 41, main body 41 is by rubber
Be made with damping material, be embedded portion 42 and be made up of metal material, being embedded portion 42 has two groups, be embedded respectively on the top of main body 41 and
Bottom, is embedded portion 42 and is provided with screwed hole, in order to be connected with support 11 and base plate 21.
Permasyn morot 1 also includes stator, in order to reduce seat No., material usage is reduced, so that it is same to reduce permanent magnetism
The manufacturing cost of motor 1 is walked, after the reference frequency of permasyn morot 1, but the flat rate raising of benchmark can be improved, in other ginsengs
In the case that number keeps constant, stator iron loss will increase, and the length for shortening stator core can reduce stator iron loss, be computed,
It is optimal when the length of stator core is the 65% ~ 75% of the length of the stator core of the standard permasyn morot of same specification,
So, the efficiency of permasyn morot 1 still can reach 1 grade of efficiency.
By taking Y2 series 132M-6 permasyn morots as an example, when the reference frequency of permasyn morot 1 is carried by 50Hz
During up to 150Hz, stator iron loss is calculated according to following formula:
Wherein:It is empirical coefficient, typically takes 2.5 ~ 2.0;
It is the loss that unit weight is unshakable in one's determination;
It is magnetic induction intensity;
WithIt is reference frequency,It is the reference frequency before change, is 50Hz in the present embodiment,After raising
Reference frequency, is 150Hz.
、、In the case of keeping constant, the reference frequency of permasyn morot 1 is improved by 50Hz
During to 150Hz, under weight the same terms, stator iron loss will increase for stator coreI.e. 4.17 times, by the length of stator core
When shortening to 130mm, stator iron loss is accordingly reduced, and now stator iron loss can be controlled in 285w or so, the synchronous permanent-magnet motor
The efficiency of machine 1 still can reach 1 grade of efficiency.
In order to reduce stray loss, stator core uses the structure type of skewed slot.
The copper factor of stator winding is improved, makes its control in the range of 78% ~ 80%, copper loss can be reduced.Improve stator around
The copper factor of group is mainly by increasing the copper consumption in stator slot to realize, this can be by changing the groove profile knot of stator slot
Structure, or, in the case where the trench structure of stator slot is constant, realized by improving winding diameter or modes of emplacement.
Permasyn morot 1 also includes rotor 12, and rotor 12 includes rotor core 121 and magnet steel 122, in magnet steel 122
It is embedded in rotor core 121, and magnet steel 122 is close to the outer circumference surface of rotor core 121 in rotor core 121, so so that
The consumption of magnet steel 122 is less, cost-saved, and because magnet steel 122 is embedded in rotor core 121, magnet steel 122 is not allowed
Easily deviate from from rotor core 121 so that reliable.
In order to further reduce stray loss, it is ensured that the efficiency of permasyn morot 1 can reach 1 grade of efficiency, can increase
The gas length of permasyn morot 1, the gas length of the permagnetic synchronous motor is 1.0 ~ 4.0, and concrete numerical value can be according to forever
Magnetic-synchro rating of machine sets.By taking Y2 series 132M-6 permasyn morots as an example, gas length increases to 1.0 by 0.35
Afterwards, stray loss can be made to control in 170w or so.
To sum up, the feed pump of the invention changes turning for permasyn morot with drive device by variable-frequency governor
Speed, so as to adjust pump capacity, can reduce energy consumption, and the manufacturing cost and use cost of the feed pump are relatively low, so as to can reduce
Its selling price, can about reduce by 35% or so, while can make the cost and selling price of variable-frequency governor also reducing, about may be used
Reduce by 45.23%.In addition, the efficiency of the permasyn morot in the drive device can reach 1 grade of energy efficiency market, the driving
Noise during plant running is smaller, can reach 55dB (A).
Above-described embodiment method only to illustrate the invention is conceived and feature, and personage's energy of this method is familiar with its object is to allow
Solution present disclosure much of that is simultaneously implemented according to this, and it is not intended to limit the scope of the present invention.It is all spiritual according to the present invention
