Description
Technical field
The utility model relates to a kind of pump, relates in particular to a kind of energy-conservation canned pump.
Background technology
At present, the canned pump that is widely used in the fields such as oil, chemical industry, light industry, medical industry is by motor and pump group all-in-one-piece no-leakage pump, its main feature is to be provided with housing at motor stator inner surface and rotor outer surface, and housing is non-magnet_conductible material, in fact strengthen the non-magnetic gap between stator and rotor; Thereby cause pump power consumption to increase, and shielded motor is low 10 percentage points with number of poles common motor phase specific efficiency with same power, and power factor is lower.
Utility model content
The purpose of this utility model, exactly in order to address the above problem, provides a kind of energy-conservation canned pump.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of energy-conservation canned pump, comprise the pump housing, impeller, rotating shaft and high-efficiency energy-saving motor, impeller is installed in the front portion of rotating shaft, the rotor assembly of high-efficiency energy-saving motor is installed at the rear portion of rotating shaft, and described rotor assembly comprises rotor core, rotor shielding sleeve and rotor baffle plate; Described rotor assembly also comprises permanent magnet, has permanent magnet trough in rotor core inside, and permanent magnet embeds in permanent magnet trough, and rear and front end is fixed with rotor baffle plate.
Described permanent magnet trough is axially offered and front and back perforation along rotor core, and permanent magnet is full of whole permanent magnet trough.
Totally four of described permanent magnet trough, four permanent magnet trough are symmetrical in rotating shaft and are arranged in rotor core and orthogonal arrangement.
Between adjacent permanent magnet groove, be provided with every magnetic magnetic bridge.
Described permanent magnet is made by Nd-Fe-Bo permanent magnet material.
The maximum degaussing working point scope of described permanent magnet be set to Nd-Fe-Bo permanent magnet material used in the time of maximum operating temperature demagnetization curve flex point 110%～150%.
The utility model has the advantages that magnetic circuit is radial structure, a bit simple in structure, leakage field is less, due to the restriction in space, it is special in magnetic mode to take, reduce to increase magnetic resistance every the size of magnetic bridge, leakage field is reduced, use less Nd-Fe-B permanent magnet can provide motor required air gap flux density.The utility model improves the whole efficiency of pump, utilize Nd-Fe-Bo permanent magnet material, make that electric efficiency is high, power factor is high and power density is large, overload capacity is strong, and temperature rise is low, noise is little, long term high temperature when operation reliability is high, without the feature such as leaking, explosion-proof, anti-corrosion, anticorrosion, and can normally operation at 200 DEG C.
