Description
Technical field
The present invention relates to centrifugal pumping apparatus field, it particularly relates to it is a kind of without frame permagnetic synchronous motor directly drive from
Heart pump.
Background technology
Centrifugal pump is that a kind of general hydraulic its internal flow situations are always asking of extremely paying close attention to of pump designer
Topic, because the quality of flowing directly affects the performance of pump in pump.The internal flow of centrifugal pump impeller is very complicated equal Three-dimensional Turbulent Flow
Flowing, is fluid work simultaneously because being influenceed also to be mixed with the phenomenon of the separation of flow, backflow and Secondary Flow by rotation and blade surface curvature
One of more difficult experimental study and numerical value computational problem in journey.
Early in the 5O ages in 20th century, some experts and scholars begin to attempt to predict in impeller using numerical computation method
Mobility status.But the interior stream numerical simulation with complete form, it is considered that start from the relative stream of the class of S1, S2 two of Wu Zhonghua professors
After foliation opinion, stream numerical simulation is just developed rapidly in turbomachine.So far, domestic many scholars are to centrifugation
Impeller of pump interior three-dimensional Numerical modelling of turbulent flow is studied, and also achieves some achievements, but unsatisfactory, is also lacked experiment and is tested
Card.Have benefited from the high speed development of computer technology, computation fluid dynamics (Computational Fluid in recent years
Dynamics) it have developed rapidly, many commercial CFD codes are applied widely, answering on centrifugal pump Inner Flow Simulation
With also increasing day by day.Numerical simulation is carried out to centrifugal pump impeller internal flow by CFD approach, liquid stream is understood in impeller flow passage
Speed and pressure distribution in part, so that carry out the type selecting of blade, design and performance prediction has turned into the important of modern pump technology
One of method.
In the storage and Transportation Engineering of petroleum gas, various pipe transporting fluid machineries are widely used, for increasing stream
The energy of body overcomes flow resistance, reaches the purpose along Pipeline transport.Centrifugal pump is a kind of quite varied general of application
Hydraulic, it is widely used in water supply and drainage and agriculture project, Industrial Engineering, Aero-Space and navigation engineering, energy work
Journey, Vehicle Engineering etc..And rapidly expand with its application that develops rapidly of modern science and technology.With should
With the expansion of scope, working environment also becomes increasingly complex, and modern project technology is to the performance requirement more and more higher of pump, traditional base
The design method being combined in experience and model test is extremely difficult to such design requirement.The general process of traditional design method
For：Design a Prototype Test and detect a manufacture, such trial-manufacture of sample and performance detection will entirely be designed and also by multiple
By being repeated several times, it is clear that the shortcoming of traditional design method is design cycle length, design cost height.The construction cycle of product is long
The bottleneck for being difficult to go beyond as centrifugal pump new product development with design cost height.Accordingly, it would be desirable to explore new Centrifugal Pump Design method.
In the development process of traditional pump, a successful the Hydraulic Design model often will be by repeatedly performance is tried repeatedly
Testing model modification could complete, as computational fluid dynamics is in the Successful utilization of other industries, now, it is entirely possible to use
Computational fluid dynamics (CFD) simulating analysis replaces performance test, and preliminary 3-D Moulding Design is completed on computers
Afterwards, so that it may carry out the check in flow field and predict pump performance, so as to shorten product development cycle and reduce cost.
In addition, being reported according on national Fluid Machinery and Engineering International Academic Conference：Pump be it is a kind of be widely used, consume energy it is big
Universal fluid machinery, the power consumption of the annual various pumps of China constitutes about the 20% of national total power consumption, and fuel consumption constitutes about national total
The 50% of fuel consumption.Centrifugal pump is that using widest in area general, and the overall efficiency of general centrifugal pump only has in various pumps
50%-60%, the operational efficiency average specific foreign countries low 10%-30% of China's centrifugal pump, energy conservation potential is about 300-400 hundred million kilowatts
When, therefore it will be highly important to improve the performance and efficiency of pump.Therefore it is badly in need of carrying out the research work of this respect, makes full use of
Existing direct-drive technology, studies the centrifugal pump that a kind of new permagnetic synchronous motor directly drives, further improves the efficiency of pump, so that from whole
Its cost performance is improved on body.
Existing centrifugal pump be generally motor by shaft coupling or belt drive impeller, exist it is complicated, safeguard inconvenience, transmission
Efficiency is low, high energy consumption the shortcomings of.Therefore, need badly and design a kind of new centrifugal pump directly driven without frame permagnetic synchronous motor, to solve
Certainly deficiencies of the prior art.
