The each department of national economies such as oil, chemical industry metallurgical, mine, urban construction, nuclear power and defence and military,
Become irreplaceable equipment in various fluid means.Along with national economy especially fluid work
The fast development of industry, electric pump has obtained the most universal and extensively application in China, and electric pump manufactures skill
Art level also improves constantly, and has possessed perfect technology production system, has defined sizable life
Product scale.Whole nation family of all kinds of electric pump manufacturing enterprise more than 6000, key enterprise of Beng Ye association realizes
The output value more than 400,000,000,000 yuan, it is achieved profits tax total value 40,000,000,000 yuan, it has also become the whole world is most important
Electric pump industry produce and one of exported country.In recent years, although the electric pump of China has significant progress,
But there is also some practical problems, it directly affects economic benefit and the society of electric pump industry
Benefit.
Traditional submersible pump is that the principle using threephase asynchronous machine is fabricated by, this product
Being product in the market, its subject matter is in the following aspects: 1. axial force cannot solve
Certainly, it is to support with the thrust disc of motor bottom, but the Fast Wearing of thrust disc makes motor
Cannot normally use, especially cannot use on high-lift submersible pump.2. volume is big, matter
Amount weight, is unfavorable for that user uses.Especially speedily carrying out rescue work in colliery, Urban Waterlogging etc. can move at any time
Local highly difficult.3. manufacturing difficulty, complex process, properties of product are unstable, and cost is high.4.
Electric pump efficiency is low, and power factor is low, does not reaches energy-saving product.5. cannot adjust the fortune of motor
Rotary speed, does not reaches total head work.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, it is provided that a kind of service life length, volume little,
The magnetic suspension permanent magnet submersible pump that efficiency is high.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is: a kind of magnetic suspension permanent magnet
Submersible pump, including magnetic suspension permanent magnet motor and water pump；Described magnetic suspension permanent magnet motor is by connection
Axial organ is connected with water pump；Described magnetic suspension permanent magnet motor includes central shaft, and central shaft is fixed with
Rotor, is set with stator outside described rotor；Described central shaft one end connects has axial force to regulate machine
Structure；Described axial force governor motion includes the magnet steel that two pieces of magnetic be arrangeding in parallel is identical.Use
This programme, by arranging two blocks of identical magnet steel of parallel magnetic, utilizes same magnetic to repel
Principle eliminates axial force, counteracting force produced by two magnetic poles, adds pump shaft equal to impeller deadweight
Deadweight adds axial force produced by fluid pressure.Thus reach to eliminate the purpose of axial force.
Described axial force governor motion includes the magnet steel seat for placing described magnet steel, at the bottom of described magnet steel seat
End is provided with regulation bolt, adjusts the spacing between described two blocks of magnet steel by regulation bolt.Adopt
With this programme, the distance between two magnetic poles can be adjusted according to the size of axial force.
It is provided with permanent magnet on described rotor.Our company have employed magnetic suspension permanent magnet motor and improves electric pump
Efficiency and power factor, simultaneously on rotor, have employed permanent magnet, it is not necessary to idle excitation electricity
Stream, can significantly improve power factor, can reach even capacitive, decrease rotor current, turns
Sub-resistance loss, total losses reduce, and the efficiency of motor can improve 10--15 than the motor of same specification
Percentage point.And, magnetic suspension permanent magnet motor is in 25--120% rated load ranges
Keeping higher efficiency and power factor, when making light running, energy-saving effect becomes apparent from.Simultaneously
The present invention uses magnetic suspension, makes mechanical loss reduce, and improves the efficiency of electric pump, energy-saving effect
Significantly improve, 20--30% can be improved.
The present invention compared with prior art has a following beneficial effect:
The most compared with prior art, the present invention does not use traditional side installing thrust disc in motor bottom additional
Formula solves axial force, it is to avoid cause making the electrical machinery life contract because thrust disc is the most easy to wear
Short.Use this programme, by arranging two blocks of identical magnet steel of parallel magnetic, utilize same magnetic
Property repel principle eliminate axial force, counteracting force produced by two magnetic poles, equal to impeller from
Heavily add pump shaft deadweight and add axial force produced by fluid pressure.Thus reach to eliminate the mesh of axial force
's.The most traditional submersible pump is big along with the change of the power of motor, and the diameter of electric pump becomes big, matter
Quantitative change weight.The present invention uses magnetic suspension permanent magnet motor, and the volume reaching electric pump is little,
The purpose of light weight, traditional motor speed is 2900 revs/min, and magnetic suspension permanent magnet motor
Rotating speed be 0--8000 rev/min, in the case of same power is constant, the volume of electric pump
Being traditional 1/5, quality is traditional 1/5, the performance of product and do not change.Reach simultaneously
To the reduction of material, the reduction of cost.3. the present invention uses magnetic suspension permanent magnet motor, so that
During processing, technique is simple, easily manufactured, stable performance, and cost reduces.
