Abstract

A high-efficiency shield pump relates to an improvement of a shield pump structure. The invention provides the high-efficiency shield pump with good energy-saving effect. The high-efficiency shield pump comprises a motor, and a rotor on a motor shaft corresponds to a stator in a housing. The structure is characterized in that a rotor magnetic conduction shield cover of a magnetic conductive material is arranged on the outer surface of a rotor core, and a rotor non-magnetic conductive shield cover of a non-magnetic conductive material is arranged on the other parts of the outer surface of the rotor core; a stator magnetic conduction shield cover of the magnetic conductive material is arranged on the inner surface of a stator core, and a stator non-magnetic conduction shield covers of a non-magnetic conductive material is arranged on the other parts of the inner surface of the stator core.

Description

A kind of high-efficiency shield pump
Technical field:
The present invention 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.
Summary of the invention:
The present invention is exactly to the problems referred to above, and a kind of high-efficiency shield pump of good energy-conserving effect is provided.
For realizing above-mentioned purpose; The present invention adopts following technological scheme; The present invention includes motor; Rotor on the motor reel is corresponding with the stator in the housing, and 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.
Beneficial effect of the present invention:
Because rotor core outer surface of the present invention 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 present invention significantly reduces the effective non-magnetic conduction gap between stator and the rotor, can accomplish identically with the common motor air gap, reduced the power loss of power transmission process, and canned motorpump whole efficiency and power factor obviously improve, and energy-saving effect is remarkable.The energy index of motor of the present invention 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 invention 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.
