Abstract
The invention is concerned with the non-impeller induction-type centrifugal pump driving by liquid state metal magnetic force, the characteristic is: the Nd_Fe_B magnetic pole setting on the support of external rotor rotary grows the rotating magnetic field driving by the motor and the redactor, the rotating magnetic field crosses the thermal insulating layer and the volute pump body of the high-temperature anti-friction material to affect the liquid state metal, in order to drive the liquid state metal high-speed rotate to create centrifugal force, the liquid state metal inhales from the entrance by the centrifugal force and outflows with high-speed from the exit. The invention can save cast, save energy effectively.
Description
Technical field
The present invention is the pump class, is that the liquid metal with magnetic drive does not have impeller induction type centrifugal pump.
Technical background
At present, adopt electromagnetic pump for the transmission of liquid metal, electromagnetic pump can be divided into conduction pump and induction electromagnetic pump more, and wherein conduction pump is divided into direct-current electromagnetic pump and single phase alternating current (A.C.) conduction pump again; Induction electromagnetic pump is divided into plane induction type and cylinder type electromagnetic pump.The operation principle of above electromagnetic pump is based upon on the linear electric motors basis, and principle of the present invention is based upon on the centrifugal pump basis, the source of its field of magnetic forece has two kinds, first method is to adopt electromagnetism to produce rotating magnetic field, it is simple in structure adopting the advantage of electromagnetism, control flexibly, but energy consumption height, second method is to contain abundant strong magnetic rare earth permanent-magnetic material Nd-Fe-B magnetic pole with China, its magnetic field is that self is intrinsic, the drive unit that required power is less makes its rotation, and then the generation rotating magnetic field, so it is energy-efficient, it is useful promoting the application of rare earth permanent-magnetic material Nd-Fe-B magnetic pole in today of energy worsening shortages.
Summary of the invention
Non-impeller centrifugal pump with liquified metal magnetic driven of the present invention has overcome the deficiency of existing high-temperature metal transmission pump, and it is the liquid metal transmission centrifugal pump that drives with permanent magnet.Rare earth permanent-magnetic material is contained abundant in China, with its be the energy then cost is low, efficient is high, energy-conservation.
Main part of the present invention comprises the spiral case pump housing, external rotor, reductor, motor.
The external type of volute pump is a scroll casing shape, and internal layer is the pump chamber of high-temperature and wear-proof, and the intermediate layer is the heat-insulation and heat-preservation material, outer liquid metal import and liquid metal export mixes of reinforcing with austenitic stainless steel.
External rotor comprises Nd-Fe-B magnetic pole magnetic pole and external rotor rotating disk support.
The technical solution adopted for the present invention to solve the technical problems is: reductor drives the external rotor rotation by motor, thereby external rotor drives the Nd-Fe-B magnetic pole magnetic pole rotation that is installed on the external rotor rotating disk support and produces rotating magnetic field, the spiral case pump housing that rotating magnetic field is passed insulation layer and high-temperature and wear-proof acts on liquid metal, the liquid metal cutting magnetic line produces induced current, this induced current is in this magnetic field and be subjected to the effect of power, thereby producing moment causes the rotation that liquid metal produces and magnetic field is equidirectional to drive the liquid metal rotation, at this moment Xuan Zhuan liquid metal is equivalent to the impeller of centrifugal pump, the liquid metal of rotation produces centrifugal force, liquid metal sucks from the liquid metal import under action of centrifugal force, flows out the pump housing at a high speed from the liquid metal outlet.

Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
Non-impeller centrifugal pump with liquified metal magnetic driven mainly is based on the principle of centrifugal pump and electromagnetic hydroimechanics theory, according to the principle of conductor in the action of a magnetic field lower stress and generation motion, by pump housing internal magnetic field being distributed and the size of fluid induced currents is carried out theoretical analysis and calculation, and on the basis of experimental analysis, successfully develop.
The pole material of non-impeller centrifugal pump with liquified metal magnetic driven is most important, and the first-selected Nd-Fe-B magnetic pole material of the present invention is Nd-Fe-B magnetic pole magnetic pole (1).Adopt multipole uniformly, the N utmost point and the S utmost point are staggered, and are installed on the external rotor rotating disk support (3), and multipole is (this device has only been used four Nd-Fe-B magnetic pole magnetic poles) that power and rotating speed according to pump carry out the concrete numerical value of Design Theory.Drive external rotor (2) rotation by motor (8) and reductor (9), thereby generation rotating magnetic field, rotating magnetic field passes insulation layer (6) and high-temperature and wear-proof (4) acts on liquid metal, thereby drive the liquid metal high speed rotating and produce centrifugal force, liquid metal sucks from liquid metal import (10) under action of centrifugal force, flows out the pump housing at a high speed from liquid metal outlet (11).
The spiral case pump housing (5) is installed below external rotor (2), and the spiral case pump housing (5) is to be internal layer with high-temperature and wear-proof (4), and the intermediate layer is insulation layer (6), and skin is that the outer reinforced stainless steel of pump case (7) is reinforced an overfill protection.
