Abstract
An energy-saving canned motor pump comprises a pump body, an impeller, a rotating shaft and a high-efficiency energy-saving motor. The impeller is mounted at the front part of the rotating shaft, and the rotor assembly of the high-efficiency energy-saving motor is mounted at the back part of the rotating shaft. The rotor assembly comprises a rotor core, a rotor shielding sleeve and rotor baffle plates. The rotor assembly further comprises a permanent magnet. The rotor core is internally provided with a permanent magnet trough. The permanent magnet is embedded into the permanent magnet trough. The front end and the back end of the permanent magnet are fixed by the rotor baffle plates. The energy-saving canned motor pump has advantages of simple structure, high motor efficiency, large power factor, high power density, high overload capability, low temperature increase, small noise, high reliability in long-term high-temperature operation, no leakage, high explosion resistance, high corrosion resistance, etc.
Description
Technical field
The present invention relates to a kind of pump, particularly relate to a kind of energy-conservation canned pump.
Background technology
At present, the canned pump being 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 that motor stator inner surface and rotor outer surface are provided with housing, and housing is non-magnet_conductible material, in fact increase the non-magnetic gap between stators and rotators; Thus cause pump power consumption to increase, shielded motor is low 10 percentage points with number of poles common motor phase specific efficiency with same power, and power factor is then lower.
Summary of the invention
Object of the present invention, exactly in order to solve the problem, provides a kind of energy-conservation canned pump.
In order to achieve the above object, present invention employs 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 stop 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 rotor stop plate is fixed.
Described permanent magnet trough to be offered and front and back are through along the axis of rotor core, and permanent magnet is full of whole permanent magnet trough.
Described permanent magnet trough totally four, four permanent magnet trough are symmetrical in rotating shaft and are arranged in rotor core and orthogonal arrangement.
Be provided with every magnetic magnetic bridge between adjacent permanent magnet groove.
Described permanent magnet is made by Nd-Fe-Bo permanent magnet material.
The maximum degaussing operating point range of described permanent magnet be set to Nd-Fe-Bo permanent magnet material used when maximum operating temperature demagnetization curve flex point 110% ~ 150%.
Advantage of the present invention is magnetic circuit is radial structure, and a little structure is simple, 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 air gap flux density needed for motor.The present invention makes the whole efficiency of pump improve, 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, when long term high temperature runs, reliability is high, No leakage, the feature such as explosion-proof, anti-corrosion, anticorrosion, and normally can run at 200 DEG C.
