Abstract
The utility model relates to a one-way rotation submersible pump, which comprises a shell body, a stator which is fixed in the shell body and is sealed by resin, a rotor which is made of a permanent magnetic body, an impeller which is fixed on the shaft end of the rotor, a press cover, an adjusting sheet, and a filtering cover. The one-way rotation submersible pump also comprises a movable blocking sheet. The movable blocking sheet is hinged on the shell body on one side of the impeller, and the length of the movable blocking sheet can be swung into the rotation range of the impeller. A rotation limiting convex head is arranged on the shell body on one side of the movable blocking sheet, and a cavity which can cause the contact of the movable blocking sheet and the impeller is disengaged is arranged in the shell body on the other side. The impeller is only rotated towards one direction by the one-way rotation submersible pump through the movable blocking sheet, which overcomes randomness. The design of vanes of the impeller is more reasonable. The lifting range and the work efficiency of the one-way rotation submersible pump are enhanced, and the flow amount of the one-way rotation submersible pump is stabilized.
Description
Affiliated technical field
The utility model relates to water pump, and particularly a kind of one-way rotation submersible pump is fit to aquarium, fountain and potted landscape and uses.
Background technique
In the prior art, the small-sized submersible pump that is used for aquarium etc. adopts permagnetic synchronous motor to drive usually, to satisfy the requirement of underwater operation.Because the rotor rotation direction of this motor is a randomness, no matter the thataway rotation can both be evacuated to water in the outlet pipe in order to make blade, its blade all is vertical radial design, therefore makes water pump be difficult to improve performance characteristic, improves its utilization efficiency and lift, regime flow.
Summary of the invention
The purpose of this utility model is to solve the existing problem of prior art, and a kind of one-way rotation submersible pump is provided, and it can improve diving lift of pump and working efficiency effectively.
Task of the present utility model is achieved by the following technical solution: the rotor that this one-way rotation submersible pump comprises housing, be fixed in the housing and make with resin-sealed stator, with permanent magnet, be fixed in impeller, gland, adjustment sheet and the filtering cover of rotor axle head, it also comprises an active baffle piece, this activity washer is articulated on the housing of impeller one side, its length can be put to the wheel rotation scope, being provided with a limit on the housing of active baffle piece one side changes plush copper, is provided with one and can allows active baffle piece break away from and the impeller cavity in contact in the housing of opposite side.
Owing to done above-mentioned improvement, when connection power supply, rotor begin to rotate at random, when if the direction that its sense of rotation and active baffle piece can not be swung is consistent, this active baffle piece is just run into limit changes plush copper, has hindered the rotation of impeller, and its reaction force must make the impeller backward rotation, the active baffle piece of this moment is just put to the cavity of reserving, do not influence the rotation of impeller, thereby the randomness of rotor rotation is changed, can only rotate towards a direction.Only rotate just because of impeller of the present utility model, make its design more reasonable, can adopt the cutting type blade of general water pump, satisfy the eddy current requirement, thereby can raise the efficiency effectively and lift towards a direction, but and regime flow.
Description of drawings
Fig. 1 is that a kind of axle of one-way rotation submersible pump concrete structure is surveyed erection drawing.
Fig. 2 is the front view that removes gland (5) and filtering cover (6) among Fig. 2.
Embodiment
Referring to figs. 1 through Fig. 3, a kind of one-way rotation submersible pump comprises housing 1, places in the housing 1 and with the stator 2 of epoxy sealing the rotor made from permanent magnet 3, be arranged at the impeller 4 of rotor shaft front end, gland 5, the filtering cover 6 that cooperates with housing 1 and place adjustment sheet 7 in the filtering cover 6.The utility model also comprises an active baffle piece 8.One end of this activity washer 8 is articulated in impeller 4 one side bodies 1 axis hole 10 by its rotating shaft 9, and its length can be put to the slewing area of impeller 4.Establishing a limit in a side of active baffle piece 8 changes plush copper 11, is provided with one and can allows active baffle piece 8 break away from and impeller 4 cavity in contact 12 in the housing 1 of opposite side.13 is water outlet among Fig. 1, and 14 is sucker.
