Description

A kind of hermetic water pump stator

Technical field

The utility model relates to the particularly a kind of parts on the immersible pump of water pump, specifically is a kind of hermetic water pump stator.

Background technology

Motor is the important component part of water pump, immersible pump, and the stator requisite vitals that is motor.Stator generally includes plastic core frame, stator core, enamelled wire winding and power outlet.Because the enamelled wire in the stator punctures because of the stator water inlet easily, both influenced the useful life that also influences product safe in utilization of product, so for water pump particularly for the immersible pump, it is particularly important that the water-tight of motor just seems.

The motor for submerged pump of usefulness adopts the stator of motor housing hermetically-sealed construction with the protection the inside usually in the market.What generally adopt is the iron plate moulding, adopts the upper and lower covers form to add that reinforced seal seals, and this form has its several shortcomings: the enamelled wire of stator is exposed, in case reinforced seal was lost efficacy, be easy to cause the stator water inlet to puncture, and oxidized easily, bump easily in the transportation disconnected, modification etc.In case a damage parts is arranged in several parts, and whole motor will be scrapped.

The motor that adopts the integral molded plastic hermetically-sealed construction is also arranged, be about to the full annular stator with the plastics casting in pump housing shell, or whole motor housing is integral molded plastic and forms.As Chinese patent CN89215248.6 disclosed " corrosion-resistant hermetically sealed centrifugal pump ", CN90206030.9 disclosed " the hermetically sealed electronic centrifugal pump of annular " etc.Such technology has solved the seal failure problem substantially, but still exists as long as a damage parts is arranged, the deficiency that whole motor will be scrapped in several parts.And for an enterprise, its product specification, model, profile are more usually, and it must all prepare at least one mold at the product of each type like this, has increased the production cost of enterprise virtually.

Summary of the invention

Technical problem to be solved in the utility model is the present situation at prior art, and the hermetic water pump stator that a kind of sealing is good and versatility is good is provided.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the hermetic water pump stator of the utility model, it has plastic core frame, stator core, enamelled wire winding and power outlet, it is characterized in that the outer integral coating of described plastic core frame, stator core and enamelled wire winding have one deck one-body molded and plastic layer.

This plastic layer both can be a continuous plastic layer at the inner ring surface place (promptly with the rotor cooperation place) of stator core, the inner ring surface that is stator core also is coated with a plastic layer, it also can be interrupted plastic layer, promptly only in the groove of stator core, slit, be filled with plastic layer, as long as whole inner ring surface is a whole level and smooth face of cylinder.But the preferred latter, promptly described plastic layer is concordant with the inner ring surface of stator core and make the inner ring surface of the plastic layer at this place and iron core be the face of cylinder of a smooth and continuous on the whole at the inner ring surface place of stator core.

Further, the axial two ends of described stator core have motor bonnet installing port, rotor bearing installing port and the reinforced seal installing port that is made of described plastic layer, to simplify the structure of whole stator.

The utility model compared with prior art has the following advantages:

One, saves national resources, replace national resources iron resource in short supply with chemical plastic.

Two, cost descends, iron plate moulding more originally, and cost has had significantly reduction, makes product that better competitiveness arranged on market.

Three, manufacture craft is easy, has reduced more operation, has simplified the assembling of complete machine, and manufacturing cost also has significantly reduction.

Four, good seal performance, even reinforced seal was lost efficacy, stator can not be affected yet, because empty G﹠W is separated fully by covered plastics layer, has avoided adopting some drawbacks of iron plate moulding.

Five, versatility is good in other words for interchangeability.The overall plastic product of part is arranged at present, in case one of them parts damages, entire machine will be scrapped, and product design is limited by existing mold and can not arbitrarily changes.And stator of the present utility model can be equipped with the motor of different profiles.

Six, return of goods reclamation rate height, in a single day present motor returns goods, and motor is scrapped substantially, but uses motor of the present utility model, can guarantee the recycling of motor stator at least.

Fig. 2 is the vertical view of Fig. 1.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment

As shown in Figure 1 and Figure 2, the hermetic water pump stator of present embodiment, it has plastic core frame (not shown), stator core 1, enamelled wire winding 2 and stretches out the outer power outlet (not shown) of stator.As seen from the figure, described plastic core frame, stator core 1 and enamelled wire winding 2 outer integral coating one deck integrated injection molding is arranged and plastic layer 3, and this plastic layer 3 is concordant and make the inner ring surface 11 of the plastic layer 3 at this place and stator core be the face of cylinder of a smooth and continuous on the whole at the inner ring surface 11 of inner ring surface 11 places of stator core and stator core, that is to say, this plastic layer 3 is interrupted at inner ring surface 11 places of stator core, promptly only in the groove of stator core, slit, be filled with plastic layer, but whole inner ring surface is a whole level and smooth face of cylinder.In addition, the axial two ends of described stator core 1 have motor bonnet installing port 31, rotor bearing installing port 32 and the reinforced seal installing port 33 that is made of described plastic layer 3.

The use of the utility model water pump stator is: rotor is fitted into bore of stator, the bearing of rotor one end is assemblied in the described rotor bearing installing port 32, the other end then is assemblied in the installing port on the motor bonnet, the motor bonnet then is assemblied in the described motor bonnet installing port 31, and then finishes reinforced seal and get final product.

Claims (3)

1, a kind of hermetic water pump stator, it has plastic core frame, stator core, enamelled wire winding and power outlet, it is characterized in that the outer integral coating of described plastic core frame, stator core and enamelled wire winding have one deck one-body molded and plastic layer.

2, hermetic water pump stator according to claim 1 is characterized in that described plastic layer is concordant with the inner ring surface of stator core and make the plastic layer at this place and the face of cylinder that inner ring surface unshakable in one's determination is a smooth and continuous on the whole at the inner ring surface place of stator core.
