Abstract
The utility model discloses a closed submersible pump, which comprises a water pump body, a rotor and a rotating shaft, wherein the water pump body is provided with a rotor chamber. The rotor and the rotating shaft are integrated, the closed submersible pump is provided with a plastic bearing and can also be provided with a rubber sealing plug or a silica gel sealing plug, the rotor penetrates through the plastic bearing and is in clearance fit with the same, an opening end of the rotor chamber is blocked by the plastic bearing, the sealing plug and the rotor chamber are in close fit, a groove is arranged in the middle of the sealing plug, the plastic bearing is fastened into the groove, and the rotor penetrates through the sealing plug and is in small interference fit with the same. Due to the above closing structure, the rotor chamber can be isolated from the outside, loss of lubricating media in the rotor chamber is effectively prevented, the sealing plug made of rubber is fine in elasticity, and accordingly, noise can be effectively reduced during working of the submersible pump.
Description
Technical field
The utility model relates to a kind of submersible pump, relates in particular to a kind of closed circulation submersible pump.
Background technique
All kinds of material fountains of Cai Yonging are made the scape pump in the market, such as family expenses air-cooling fan, humidifier circulation submersible pump, its rotor is normally open, and the lubricant medium in its rotor chamber runs off easily, can cause problems such as rotor and axle serious wear, greatly reduce the working life of water pump.
The model utility content
The utility model provides a kind of closed submersible pump in order to solve the problem that prior art exists, and can effectively reduce the loss of lubricant medium, reduces the wearing and tearing of rotor and axle.
The technical solution of the utility model is: a kind of closed submersible pump, comprise the water pump main body, rotor, the rotating shaft that have rotor chamber, described rotor and rotating shaft are one, also be provided with plastic bearing, described rotor passes plastic bearing, and and the plastic bearing Spielpassung, described plastic bearing clogs the opening end of described rotor chamber.
Preferably: also be provided with rubber or silica gel sealing plug, the opening end of described sealing plug and rotor chamber closely cooperates, and the sealing plug middle part has groove, and described plastic bearing snaps in this groove, and described rotor passes described sealing plug, and and its little interference fit.
Preferably: also be provided with sealing cover, described sealing cover is provided with a circle projection, forms an annular groove, and described sealing plug is fastened in this groove, and described sealing cover is fixed on the beginning end of rotor chamber, and described rotor passes sealing cover, and and its Spielpassung.
Adopt enclosed construction of the present utility model, rubber or silica gel sealing plug can be kept apart the rotor chamber and the external world, and rotor and rotating shaft are adopted one-body molded, prevent that effectively the lubricant medium in the rotor chamber runs off, and have stablized lubrication system; Sealing plug adopts rubber or silica gel material, and elasticity is relatively good, the noise that produces in the time of can reducing submersible pump work effectively.
Description of drawings
Fig. 1 shows sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in Figure 1, a kind of closed submersible pump, comprise the water pump main body 6, rotor 5, the rotating shaft that have rotor chamber, described rotor 5 and rotating shaft are one, and rotor 5 and magnet are Spielpassung, and rotor 5 one ends are fixed in the groove of rotor chamber sidewall, the other end passes plastic bearing 4, plastic bearing 4 adopts plastic material to make, and the plastic material wear resistance is relatively good, and the right-hand member of bearing along the circumferential direction outwards is provided with projection.The material of sealing plug 3 is a rubber, also can be silica gel, and its elasticity is relatively good, the noise that produces in the time of can reducing submersible pump work effectively.The middle part of sealing plug 3 is provided with groove, in the time of cooperation plastic bearing 4 is put in the groove of sealing plug 3, and is fastened on the boss place of plastic bearing 4 right-hand members.Sealing plug 3 is provided with through hole, and rotor 5 passes this through hole and and its little interference fit.
Left side at sealing plug 3 also is provided with sealing cover 2, sealing cover 2 middle parts are provided with the through hole that passes for rotor 5, its inside also is provided with a circle projection, the side of sealing plug 3 is provided with a circle groove accordingly, the projection of sealing cover 2 is engaged in the groove of sealing plug 3, and simultaneously, sealing cover 2 is fixed on the opening end of rotor chamber, thereby when supporting sealing plug 3 and plastic bearing 4, also the rotor chamber and the external world are kept apart.
Closed submersible pump of the present utility model, closely cooperate between plastic bearing, sealing plug, the sealing cover, the rotor chamber and the external world are well kept apart, and rotor and rotating shaft are adopted one-body molded, strengthen its sealing, prevent the loss of lubricant medium in the rotor chamber effectively, stablized lubrication system; Sealing plug adopts rubber or silica gel material, and elasticity is relatively good, the noise that produces in the time of can reducing submersible pump work effectively.
The above is the utility model preferred implementation only, is not to be used for limiting practical range of the present utility model, and the equivalence of being done in protection domain of the present utility model changes and modifies in every case, all should think to have fallen in the protection domain of the present utility model.
