Description

Submersible pump

Technical field

The utility model belongs to submersible pump technical field, is specifically related to a kind of submersible pump.

Background technique

Submersible pump all can be immersed in the water the drainage machinery of work as a kind of pump housing and motor, and during use, whole unit pulls the plug work.Underground water extracted earth's surface, is domestic water, speedily carry out rescue work in mine, the cooling that works, field irrigation, seawater lift, steamer adjust carry, also can be used for fountain view, also can be used for the water lift engineerings such as river, reservoir, water channel.Before submersible pump turn on pump, liquid must be full of in suction pipe and pump, after turn on pump, impeller High Rotation Speed, liquid wherein rotates together along with blade, under the influence of centrifugal force, fly away from blade outwards to penetrate, liquid speed in pump case explosion chamber of injection is slack-off gradually, and pressure increases gradually, then from pump discharge, discharge tube flows out.

At present, submersible pump many employings motor is directly connected with impeller, owing to being subject to the restriction of pump housing radial dimension, motor size is also restricted, and rotating speed is lower and non-adjustable, to such an extent as to the inefficiency of submersible pump, application area are narrower, in order to increase the working efficiency of submersible pump, it is more that the quantity of impeller is increased, and is all generally be symmetrical arranged by impeller, the stability of submersible pump at the bottom can be increased, improve the efficiency of submersible pump simultaneously.But due to this submersible pump after long-term use, the efficiency of two impellers can be different, and the right half water outlet cross-section area of two impellers is fixing, and half outlet pressure can be caused excessive, another half water outlet pressure is less, thus affects the working effect of whole submersible pump.

Summary of the invention

The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of submersible pump, and this submersible pump structure is simple, and good stability, improves the water-outlet quantity of water, and fabricating cost is low, easy to make simultaneously.

For achieving the above object, technical solution adopted in the utility model is:

A kind of submersible pump, comprise housing, motor mount is had at housing internal fixtion, in motor mount, hollow shaft motor is installed, the lower end of the hollow shaft of described hollow shaft motor and aqueous phase lead to, and upper end is connected with conically shaped, outlet pipe in turn, the divergence form conically shaped of the shape of described conically shaped is lower end to be osculum upper end be large mouth, described outlet pipe is fixed on housing by bearing, and end walls, the bottom of described housing are equipped with water inlet.

Preferably, described motor is single-stage motor.

Preferably, the cone of described conically shaped is than being 0.4---0.6.

The beneficial effects of the utility model: the utility model have employed the structure of three water inlets and same water outlet, guarantee the stability of submersible pump at the bottom; Water outlet adopts lower end to be osculum upper end is the divergence form conically shaped of large mouth in addition, and the range intensity of water is higher, and resistance is little, thus improves water-outlet quantity, reduces kinetic energy consumption, improves the working efficiency of submersible pump; Fabricating cost is low, easy to make simultaneously.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model submersible pump;

In figure: 1: outlet pipe; 2: housing; 3: motor mount; 4: water inlet; 5: hollow shaft motor; 6: hollow shaft; 7: conically shaped, 8: bearing.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, a kind of submersible pump, comprise housing 2, have motor mount 3 at housing 2 internal fixtion, be provided with hollow shaft motor 5 in motor mount 3, the lower end of the hollow shaft 6 of described hollow shaft motor 5 and aqueous phase lead to, upper end is connected with conically shaped 7, outlet pipe 1 in turn, the divergence form conically shaped 7 of the shape of described conically shaped 7 is lower ends to be osculum upper end be large mouth, described outlet pipe 1 is fixed on housing 2 by bearing 8, and end walls, the bottom of described housing 2 are equipped with water inlet 4; Described hollow shaft motor 4 is single-stage motor; The cone of described conically shaped 7 is than being 0.4---0.6; The cone ratio of the present embodiment prioritizing selection conically shaped is 0.5.

Specific works process: submersible pump is placed in water, by water inlet 4, in housing 2, in conically shaped 7, in single-stage hollow shaft motor 4, be full of water, during work, drive hollow shaft motor 4 rotor turns by electromagnetic induction, thus hollow shaft 6 rotates, hollow shaft 6 drives conically shaped 7 to rotate together, and liquid wherein rotates together along with conically shaped 7, under the influence of centrifugal force, be separated conically shaped 7 outwards to penetrate, the rotation of conically shaped 7 realizes the object of conveying water; Be full of water in the hollow shaft 6 of simultaneously hollow shaft motor 4, hollow shaft motor 4 also played to the effect of cooling, ensure that hollow shaft motor 4 is safe and reliable.

The utility model, structure is simple, improves water-outlet quantity, reduces kinetic energy consumption, improve the working efficiency of submersible pump.
