Abstract
The utility model discloses a motor seal structure for pump body. As an improvement, the structure comprises a seal cover, a seal cover coupling connected to one end of the seal cover and a seal rod connected to a linear motor mover. The seal rod is slidably arranged in the seal cover and the seal cover coupling; and the outer wall of the seal rod is in seal cooperation with the seal cover coupling. According to the utility model, one end of the seal cover is connected with the seal cover coupling, and the outer wall of the seal rod is in seal cooperation with the seal cover coupling. The utility model has the beneficial effect that the linear motor mover promotes sliding of the seal rod and can effectively prevent baring of the linear motor mover and isolate the contact of linear motor with water.
Description
Technical field
The utility model relates to a kind of pump housing motor sealing structure.
Background technology
Now widely used immersible pump in use demanding party is positioned in the water for a long time, and the drive motors of the pump housing is generally rotary drive motor, and the advantage of linear electric motors rectilinear motion in the pump housing uses obtains paying close attention to more and more widely.
But mover rectilinear motion linear electric motors lack necessary non-tight member, can not with the direct combination of the existing pump housing, pollute in order to avoid linear motor rotor is subject to the external world or water, have influence on the normal service life of linear electric motors.
Summary of the invention
The problem that the utility model in use exists for solving prior art provides a kind of to be combined with linear electric motors pump housing motor sealing structure easy to use.
The technical scheme that the utility model solves existing issue is: pump housing motor sealing structure, as improvement, comprise sealing shroud, be connected in the sealing shroud box cupling of sealing shroud one end, the seal bar that is connected with linear motor rotor, described seal bar slidably is arranged in sealing shroud and the sealing shroud box cupling, and described seal bar outer wall and sealing shroud box cupling are sealed and matched.
As further improvement, be provided with the rubber ring for sealing between described sealing shroud box cupling and the seal bar.
As further improvement, be provided with the Glan circle for sealing between described sealing shroud box cupling and the seal bar.
As further improvement, described linear motor rotor is connected by shaft coupling with seal bar.
As further improvement, described sealing shroud and sealing shroud box cupling are threaded connection.
The utility model compared with prior art, connect the sealing shroud box cupling at sealing shroud one end, seal bar outer wall and sealing shroud box cupling are sealed and matched, its beneficial effect is that linear motor rotor promotes the seal bar slip, be positioned at and can prevent effectively that linear motor rotor is exposed, isolated linear electric motors contact with water.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the implementation case sealing shroud 1, be connected in the sealing shroud box cupling 2 of sealing shroud 1 one ends, the seal bar 3 that is connected with linear motor rotor, seal bar 3 slidably is arranged in sealing shroud 1 and the sealing shroud box cupling 2, and seal bar 3 outer walls and sealing shroud box cupling 2 are sealed and matched.Sealing shroud 1 is threaded connection with sealing shroud box cupling 2, and linear motor rotor and seal bar 3 are connected by shaft coupling.
Wherein, be provided with rubber ring 4 and Glan circle 5 for sealing between sealing shroud box cupling 2 and the seal bar 3, in the middle of rubber ring 4 can be arranged at, Glan circle 5 was arranged at the upper and lower both sides of rubber ring 4.
