Description

A kind of pump impeller

Technical field

This utility model is related to agricultural water pumping equipment, particularly a kind of pump impeller.

Background technology

Usually need to go to farmland to water using water pump in agricultural planting, water pump is the conventional equipment of agricultural irrigation, and impeller It is the core component of water pump.In the running, the rotation of motor impeller, the also concomitant rotation of the blade on impeller pass through water pump Blade makes vacuum is produced in the middle of impeller, and water will be flowed into toward at vacuum, then discharges water by the impeller of high speed rotation again, rises To influence of dynamic water is pushed away, vital effect is played in thus running of the construction of impeller to water pump.

Patent No. 2011204080859 provide utility model patent --- water pump vane, blade are arranged on front shroud And back shroud between, blade edge and front shroud and bonnet plate weld form centrifugal channel, such water pump between adjacent blades Impeller is assembled and changes convenient, reduces difficulty of processing and cost, but the blade of this kind of water pump vane is easy to loosen, and makes Use short life.Patent No. 2014201932475 provide utility model patent --- improved water pump impeller, blade are fixed on On wheel disc, it is spaced with circular manner between every blade, by the impeller, the performance of water pump can be improved, reduce shaft power, But the distribution of weight of the impeller Leaf is uniform, it is difficult to produce inertia force in pumping liquid, the efficiency of drawing water of water pump is low.Cause This, needs badly and a kind of improves pumping for water pump efficiency while the water pump vane for increasing the service life.

Utility model content

For the problems referred to above, this utility model provides a kind of pump impeller, and in the impeller, wheel disc is integrated with blade Structure, the distribution of weight of blade are uneven, increase the gravity inertial of impeller, improve the efficiency of drawing water of water pump, reduce energy consumption.

The technical solution adopted in the utility model is：

A kind of pump impeller, including wheel disc and multiple blades, wheel disc are provided with centre bore, and the one side of wheel disc is provided with Support plate, blade are distributed on the another side of wheel disc around the centre bore of wheel disc, form centrifugal channel, often between adjacent blades Individual blade includes blade wall and inertia post, and inertia post is connected with an end of blade wall and edge of the inertia post in wheel disc.

Preferably, diameter of the width of blade wall less than inertia post, so causes the weight of blade one end to be more than the other end Weight, increase inertia of the impeller in rotation process, improve water pump efficiency of drawing water.

Preferably, blade wall includes straightway and arc section, and the one end of straightway is connected with the one end of arc section, is used to Property post is connected with the other end of arc section.

It is highly preferred that radius of the distance in the other end of straightway and the wheel disc center of circle more than centre bore, such blade is not Affect the installation of impeller.

Preferably, wheel disc is provided with multiple location holes, location hole along wheel disc central distribution on wheel disc, location hole runs through Support plate, each location hole is between adjacent blades.

Preferably, support plate of the centre bore on wheel disc, is provided with least one keyway in centre bore.

It is highly preferred that 6 keyways are provided with centre bore.

Preferably, wheel disc and blade are made using aluminum component.

Compared with prior art, the beneficial effects of the utility model are：This utility model provides a kind of water pump leaf Wheel, in the impeller, wheel disc is structure as a whole with blade, and the end of blade arranges inertia post, makes the distribution of weight of blade uneven, The gravity inertial of increase impeller, improves the efficiency of drawing water of water pump, reduces energy consumption.

Description of the drawings

A kind of axonometric chart of pump impeller that Fig. 1 is provided for this utility model；

A kind of pump impeller sectional view A-A that Fig. 2 is provided for this utility model；

A kind of pump impeller sectional view B-B that Fig. 3 is provided for this utility model.

Specific embodiment

With reference to the accompanying drawings the preferred implementation that this utility model is provided is illustrated.

Fig. 1 to Fig. 3, a kind of preferred implementation of the pump impeller provided for this utility model.As Fig. 1 to Fig. 3 institute Show, the impeller includes wheel disc 10 and multiple blades 20, wheel disc 10 is provided with centre bore 11, take turns, 10 one side is provided with support Disk 12, blade 20 are distributed on the another side of wheel disc 10 around the centre bore 11 of wheel disc 10, formed between adjacent blades 20 from Heart passage, makes vacuum is produced in the middle of impeller by blade, and water will be flowed into toward at vacuum, then again by the impeller of rotation at a high speed Water is discharged.Wheel disc 10 and blade 20 are made using aluminum component, mitigate weight.

Each blade 20 includes blade wall 21 and inertia post 22, and inertia post 22 is connected with an end of blade wall 21 and used Property post 22 in wheel disc 10 edge.The width of blade wall 21 so causes 20 one end of blade less than the diameter of inertia post 22 Weight of the weight more than the other end, increases inertia of the impeller in rotation process, improves the efficiency of drawing water of water pump.

Blade wall 21 includes straightway 211 and arc section 212, the one end of straightway 211 and the one end of arc section 212 Connection, inertia post 22 are connected with the other end of arc section 212.The other end of straightway 211 and the distance in 10 center of circle of wheel disc More than the radius of centre bore 11, such blade does not affect the installation of impeller.

As shown in figures 1 and 3, wheel disc 10 is provided with multiple location holes 13, and location hole 13 exists along the central distribution of wheel disc 10 On wheel disc 10, location hole 13 runs through support plate 12, and each location hole 13 is between adjacent blades 20.Centre bore 11 runs through wheel disc Support plate 12 on 10, is provided with least one keyway 111 in centre bore 11.6 keyways 111 are provided with centre bore 11.

In sum, the technical solution of the utility model can realize above-mentioned utility model purpose, and this with sufficiently effective The structure and principle of work and power of utility model all sufficiently verified in embodiment, can reach expected effect and mesh , on the premise of without departing substantially from principle of the present utility model and essence, numerous variations can be made to the embodiment of utility model Or modification.Therefore, this utility model include all be previously mentioned in patent claim in the range of all replacement contents, it is any The equivalence changes made in this utility model claim, all belong within the scope of the claims of this case application.
