Description

A kind of canned motorpump

Technical field:

The utility model relates to the improvement of shield pump structure.

Background technique:

At present, the canned motorpump of extensive use is to reveal pump by shielded motor and the combined integrated nothing of pump; Its structure main feature is to be provided with housing at motor stator internal surface and rotor outer surface; And housing is non-magnet_conductible material, in fact strengthened the non-magnetic conduction gap between stator and rotor, can reach 2～5 times of common motor air gap; Thereby cause the pump power consumption to increase, the shielding motor with power with the common motor of number of poles low 10 percentage points of specific efficiency mutually, power factor is then lower.

The model utility content:

The utility model is exactly at the problems referred to above, and a kind of canned motorpump of good energy-conserving effect is provided.

For achieving the above object, the utility model adopts following technological scheme, the utility model comprises motor, rotor on the motor reel is corresponding with the stator in the housing, its structure outline rotor core outer surface is provided with the rotor magnetic conduction housing of permeability magnetic material, and the remaining part of rotor core outer surface is the rotor magnetic conduction housing not of non-magnet material; The stator core internal surface is provided with the stator magnetic conduction housing of permeability magnetic material, and the remaining part of stator core internal surface is the stator magnetic conduction housing not of non-magnet material.

The beneficial effects of the utility model:

Because rotor core outer surface of the present utility model is provided with the rotor magnetic conduction housing of permeability magnetic material, the remaining part of rotor core outer surface is the rotor magnetic conduction housing not of non-magnet material; The stator core internal surface is provided with the stator magnetic conduction housing of permeability magnetic material, and the remaining part of stator core internal surface is the stator magnetic conduction housing not of non-magnet material; Thereby the utility model significantly reduces the effective non-magnetic conduction gap between stator and the rotor, can accomplish identical with the common motor air gap, reduced the power loss of power transmission process, canned motorpump whole efficiency and power factor obviously improve, and energy-saving effect is remarkable.The energy index of motor of the present utility model even than also good with the common motor of number of poles with power, and pulsating torque is little; Make whole canned motorpump vibration and noise all obviously reduce, the steady more and safety of equipment operation.Of the present utility model applying relies on thoroughly solve on high energy consumption, a low-quality difficult problem of obtaining the hermetically sealed transmission of canned motorpump, reached not only safety and environmental protection but also energy saving purposes.
