Abstract
The utility model relates to a stator shielding device for a shield pump. The stator shielding device comprises a stator. The outer surface of the stator is sleeved with an outer shielding sleeve. The inner surface of the stator sleeves an inner shielding sleeve. The two ends between the outer shielding sleeve and the inner shielding sleeve are provided with shielding end covers. The two ends of the inner surface of the inner shielding sleeve are provided with weld-aiding inner rings. The joints of the weld-aiding inner ringing, the inner shielding sleeve and the shielding end covers are connected through circle welding. The shielding end covers and the outer shielding sleeve are connected through circle welding. The beneficial effects of the utility model are that the production processes and cost are reduced, and the stator and stator windings are completely shielded, so that the safety and reliability are improved, and the service life of the shield pump is prolonged; and the stator shielding device is applicable to production of amphibious shield pumps, and can be used in most high-moisture high-temperature and sealed environments, so that the shield pump can be used in the environment within a wide range.
Description
Technical field
The utility model relates to a kind of stator plates shielding apparatus of canned pump.
Background technology
The driving of Ordinary Centrifugal Pumps is by shaft coupling, the impeller shaft of pump to be connected with electric drive axle, impeller is rotated together with motor and work, and canned pump is a kind of unprssurized pump, pump and drive motors are all sealed in one and are pumped in the pressure vessel that medium is full of, this pressure vessel only has static seal, and rotating magnetic field is provided and is driven rotor by an electric wire group.This structure has been cancelled the sealing device for rotary shaft that conventional centrifugal pump has, therefore can accomplish completely without leaking.The shielding construction of the motor stator of existing canned pump is generally made up of the seal at motor stator, motor housing, inner shield cover and inner shield cover two ends, difficulty of processing and the cost of inner shield cover are all higher, the described elastomeric material that the sealing at two ends adopts, elastomeric material has the risk of useful life and leakage, motor housing does not shield, can not shield extraneous water, can not use at the environment of high humidity, high temperature, sealing.
Utility model content
The purpose of this utility model is to provide a kind of stator plates shielding apparatus of canned pump, to overcome currently available technology above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of stator plates shielding apparatus of canned pump, comprise stator, described stator outer surface cover has external shroud, the inner surface cover of described stator has inner shield cover, between described external shroud and inner shield cover, two ends are equipped with shielding end cap, the two ends of the inner surface of described inner shield cover are equipped with and help ring in weldering, described in help ring in weldering, inner shield cover to be welded to connect by annulus together with triplicity place of shielding end cap, between described shielding end cap and described external shroud, be welded to connect by annulus.
Further, the external diameter of described shielding end cap equals the internal diameter of described external shroud, and the internal diameter of described shielding end cap equals the external diameter of described inner shield cover.
Further, described in, help the external diameter of ring in weldering to equal the internal diameter of described inner shield cover.
The beneficial effects of the utility model are: manufacturing process and cost all reduce, and stator and stator winding part are shielded completely, safer reliable, thus the useful life of improving canned pump.Be applicable to manufacturing amphibian canned pump, also can under the rugged environment of most of high humidity high temperature and sealing, use, thereby canned pump can used under environment widely.
Brief description of the drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the stator plates shielding apparatus of the canned pump described in the utility model embodiment.
In figure:
1, stator; 2, external shroud; 3, inner shield cover; 4, help ring in weldering; 5, shielding end cap.
Embodiment
As shown in Figure 1, the stator plates shielding apparatus of a kind of canned pump described in the utility model embodiment, a kind of stator plates shielding apparatus of canned pump, comprise stator 1, described stator 1 appearance surface cover has external shroud 2, the inner surface cover of described stator 1 has inner shield cover 3, between described external shroud 2 and inner shield cover 3, two ends are equipped with shielding end cap 5, the two ends of the inner surface of described inner shield cover 3 are equipped with and help ring 4 in weldering, described helping in weldering encircles 4, inner shield cover 3 passes through annulus welded joints seal together with 5 triplicitys place of shielding end cap, between described shielding end cap 5 and described external shroud 2, pass through annulus welded joints seal.
The external diameter of described shielding end cap 5 equals the internal diameter of described external shroud 2, and the internal diameter of described shielding end cap 5 equals the external diameter of described inner shield cover 3.The described internal diameter that helps the external diameter of ring 4 in weldering to equal described inner shield cover 3.
When concrete installation, stator 1 is compressed into external shroud 2, inner shield cover 3 is compressed into the inner circle of stator 1, shielding end cap 5 is compressed between external shroud 2 and inner shield cover 3, carry out annulus welding in external shroud 2 and shielding end cap 5 junctions, again helping ring 4 in weldering to compress into inner shield and overlap 3 inner sides, at shielding end cap 5 and inner shield cover 2 and help the junction of encircling between 4 in weldering to carry out annulus welding.Because inner shield cover 3 is very thin, very difficult and very thick shielding end cap 5 welds, and is just easy to welding so inner shield cover 3 is clipped in to the welding together with between encircling 4 in helping weldering of shielding end cap 5.Welding manner can be laser welding process, can be also argon arc welding technique, and other welding procedures.
Stator is the structure of the shielding of welding comprehensively, makes whole stator be shielded from water, makes the shielding of motor stator safer reliable, and manufacturing process is simpler, and cost is lower, thereby makes the life-span of canned pump longer.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection range of the present utility model.
