Abstract
The present invention relates to a kind of canned pump motor stator tooth support ceramic insert syndeton, tooth pressing plate of motor stator 1 tooth top fluting 4, groove internal fixtion installs a ceramic insert 2, and ceramic insert 2 is upper with tooth support 1 circumference is matched in clearance, and support ring 3 is fitted in ceramic insert 2.The present invention has been described in detail the material of ceramic insert, effect, structure and mounting means, solves the insulation difficult problem between canned pump tooth pressing plate of motor stator and support ring.Structure of the present invention is simple, easy for installation, and ceramic insert can not bring negative effect to motor performance, is conducive to the optimal design of the lifting of the efficiency of motor and the structure of housing.
Description
Technical field
The present invention relates to a kind of canned pump motor stator tooth support ceramic insert syndeton.
Background technology
The fluid isolation that canned pump motor stator winding cavity has the housing that one deck is very thin to be transported by pump, to protect motor winding not by fluid etch.Shielding mantle cavity communicates with pump chamber, subjects the system pressure of fluid, and owing to being subject to the impact of electric machine structure restriction and electromagnetism, very thin (usually at about 0.5mm) that housing must design, thus cannot bear the system pressure of high pressure, and back needs to support.
Housing adopts support ring to support at electric motor winding end place, support ring external diameter is supported by tooth support; For the less shielded motor of power, because the impact of stator end leakage field is not remarkable, stator tooth pressing plate induced currents is less, can adopt the mode that tooth support and support ring directly contact, and finally ensures the stable support to housing.For powerful shielded motor, because the impact of brow leakage be can not ignore, in the closed-loop path that tooth support, support ring and casing etc. form, there is induced current, tooth support and support ring are non-homogeneous contact time, the heating of tooth support part tooth can be very serious, causes temperature rise too high, reduce insulation life.
Summary of the invention:
The object of this invention is to provide a kind of good insulation that can ensure between tooth support and support ring, do not affect again the canned pump motor stator tooth support ceramic insert syndeton of support strength.Technical scheme of the present invention is: a kind of canned pump motor stator tooth support ceramic insert syndeton, tooth pressing plate of motor stator (1) tooth top fluting (4), groove internal fixtion installs a ceramic insert (2), ceramic insert (2) and tooth support (1) circumference are matched in clearance, and support ring (3) is fitted in ceramic insert (2).The present invention mainly designs and manufactures a kind of new construction for ceramic insert between canned pump motor stator tooth support and support ring.Insert design is square structure, loads in stator tooth pressing plate tooth top place groove, with supported ring, as shown in Figure 1.
Advantage of the present invention: ceramic material has high temperature resistant, insulation, heat conduction, non magnetic and high compression strength, and the plug-in unit adopting it to manufacture has the individual features of ceramic material equally.This ceramic insert is distributed on tooth support tooth top by fritter construction circumference, form even support face, meet the support to motor support ring, blocked the current delivery between tooth support and support ring simultaneously, prevent the local overheating of tooth support, when adjusting the temperature field of certain type canned pump tooth support, tooth support temperature before and after this structure is used to reduce nearly 30 DEG C.This ceramic insert structure is simple, easy to make, simple installation.

Embodiment
The present invention is as shown in Figure 2 a kind of canned pump motor stator tooth support ceramic insert syndeton, tooth pressing plate of motor stator 1 tooth top fluting 4, groove internal fixtion installs a ceramic insert 2, as shown in Figure 3, ceramic insert 2 is upper with tooth support 1 circumference is matched in clearance, and support ring 3 is fitted in ceramic insert 2.
Ceramic insert is arranged between tooth support and support ring, subjects the pressure of motor cavity.During installation, in radial direction, ceramic insert plug-in unit is adjacent to the bottom of tooth support fluting, and surrounding uses silicon rubber to fix, and along tooth support circumference uniform distribution, is formed all and supporting surface.Motor stator shielding is close on support ring under the effect of interior pressure, and support ring is supported by ceramic insert.
As shown in Figure 1, need according to this supporting construction and installation, devise the structure of ceramic plug-in unit in detail.Consider the high rigidity of ceramic material, during installation, inching can not be carried out by the method that polishing or machine add simply, so require higher to the formed precision of ceramic insert.Because ceramic insert is positioned at groove, break even if plug-in unit has, also still can be fixed in groove, not affect performance, and change also more convenient.
According to ceramic insert size and the requirement of design specification of Fig. 1 design, utilize the process that electrotechnical ceramics develop, have selected the ceramic material meeting design specification and instructions for use, complete material weighings, ball milling, shaping, sinter, process and performance test; By making groping of powder and sintering temperature to different process, determining the sintering temperature of ceramic insert, and completing product test product.
