Abstract

The utility model discloses a unidirectional rotating submersible pump, which comprises a housing, a motor fixed in the housing and sealed with a sealing material, an impeller fixed to the output shaft end of the motor, a gland and a filter cover, wherein the motor is a shaded pole motor. The utility model can effectively improve the head and working efficiency of the submersible pump, and has a simple structure and low cost.

Description

A kind of one-way rotation submersible pump

1, technical field:

The utility model relates to water pump, relates in particular to a kind of submersible pump of one-way rotation, is fit to occasions such as aquarium, fountain, pond, garden and potted landscape and uses.

2, background technique:

The small-sized submersible pump that tradition is used for aquarium etc. adopts permagnetic synchronous motor to drive usually, but because the rotor rotation direction of permagnetic synchronous 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 the working efficiency and the lift of water pump are all lower, be difficult to satisfy the demands of consumers, some submersible pumps by control mechanism control rotor rotation direction also appear on the market, but these water pump structures are comparatively complicated, and manufacture cost is higher.

3, summary of the invention:

In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of one-way rotation submersible pump, and it can improve diving lift of pump and working efficiency effectively.

The utility model is achieved by the following technical solution:

A kind of one-way rotation submersible pump, comprise housing, be fixed in the housing and with the motor of sealing material sealing, be fixed in impeller, gland and the filtering cover of the output axle head of motor, described motor is a motor with cup rotor.

Because shadedpole motor has only main winding, place, the two poles of the earth at motor stator respectively is provided with a secondary short-circuited conducting sleeve, after the motor energising, the pulsating field that the magnetic field of main pole part produces is responded to short circuit and is produced secondary current, thereby make the magnetic field of quilt cover part on the magnetic pole, lag behind than the magnetic field that does not cover part, thereby magnetic pole formation rotating magnetic field, motor rotor just rotates startup work.So just determined that rotor can only rotate around a direction, thereby can use the impeller of cutting type blade, improved diving lift of pump and working efficiency effectively, and simple in structure, and cost is lower.

Such scheme can be further improved by following technical measures:

The blade of described impeller is the cutting type blade.

One side of described housing is provided with a cover, this cover is provided with the perforation that the power supply machine output shaft passes, gland is installed on the cover, and gland is provided with water intake, water outlet and connection water intake and water outlet and is used for the cavity volume of ccontaining impeller, and filtering cover is installed in the water inlet of gland.

Described cover is provided with boss, and gland is sleeved on this boss, and the joint of gland and boss is provided with seal ring.

Be installed with snap ring on the described filtering cover, snap ring is threaded with the inlet end of gland.

Gland, filtering cover etc. are simple in structure, easy for installation.

The adjustment sheet that is used to adjust the water yield is installed between the cavity volume of described gland and the water outlet.

Described sealing material is an epoxy resin.

Be set with oil sealing between the inner of described motor output shaft and the cover hole inwall.

The utility model compared with prior art has following advantage: 1) adopt the fabricating cost of shaded pole motor low, running noises is less, disturbs little to electric equipment; 2) impeller of cutting type blade be can use, diving lift of pump and working efficiency improved effectively; 3) simple in structure, volume is little, in light weight.

4, description of drawings:

Fig. 1 is the utility model axle side assembling schematic representation;

Fig. 2 is a sectional view of the present utility model.

5, embodiment:

Below in conjunction with accompanying drawing the utility model is done detailed explanation:

As shown in Figures 1 and 2, the utility model comprises housing, motor 2, impeller 4, gland 5 and filtering cover 6, and this motor 2 is a motor with cup rotor.

Wherein, housing comprises main body 18 and cover 8.Main body 18 has the inner chamber 19 of a lateral opening.Cover 8 is sealed on this opening, bores a hole 9 on the cover 8, and cover 8 is provided with boss 13.

Motor 2 is fixed in the inner chamber 19 and with 1 sealing of epoxy sealing material, motor 2 output shafts 3 pass perforation 9 and extend out to outside the cover 8, are set with oil sealing 17 between perforation 9 inwalls of the inner of motor 2 output shafts 3 and cover 8.

The cavity volume 12 that gland 5 is provided with water intake 10, water outlet 11 and is communicated with water intake 10 and water outlet 11, the adjustment sheet 16 that is used to adjust the water yield is installed between cavity volume 12 and the water outlet 11, gland 5 is sleeved on this boss 13, and gland 5 is provided with seal ring 14 with the joint of boss 13.

Impeller 4 is fixed on motor 2 output shafts, 3 ends and is arranged in the cavity volume 12 of gland 5, and the blade 7 of this impeller 4 is the cutting type blade.

Be installed with snap ring 15 on the filtering cover 6, snap ring 15 is threaded with water intake 10 ends of gland 5.

During use, starting electrical machinery 2, cavity volume 12 impellers 2 that are positioned at gland 5 rotate and produce centrifugal force and export water to water outlet 11 from water intake 10.
