Abstract
The utility model discloses a shaftless pump. The shaftless pump is based on the structure of a current electric motor, and added with a pump body, a water inlet pipe, a water outlet pipe and a vane wheel of a current pump. The pump body and the shell of the electric motor are fixed together to form a water cavity, the water inlet pipe and the water outlet pipe are arranged on the pump body and communicated with the water cavity respectively, one end of the electric motor is provided with a permanent magnet rotor, and the other end of the electric motor is equipped with the vane wheel, the vane wheel is positioned in the water cavity, an electric area inner wall is disposed between the rotor and the stator, and the stator is arranged in the enclosed space formed by the electric area inner wall and the shell. With a simple structure, the utility model solves the sealing problem of a current pump, and enables safe use, reliable performance and high efficiency.
Description
The utility model relates to a kind of Non-axle water pump.
Existing water pump has consisted essentially of impeller and pump shaft, by the output shaft drive pump shaft of motor, and then makes wheel rotation reach the function of water pump.The structure of motor consists essentially of the output shaft of the housing of motor, the rotor that contains permanent magnet, the stator that is wound with coil, terminal box and motor.The common use of motor and water pump has a shortcoming that is difficult to overcome, and promptly the sealing problem between the pump housing and the pump shaft because in the course of the work, problems such as poorly sealed often occur, and pump efficiency is reduced, and needs often maintenance.
The purpose of this utility model provides a kind of Non-axle water pump, and it has solved the problem of existing water pump packing difficulty, has improved the performance of water pump, and is safe and reliable.
The technical solution of the utility model is as follows: on the architecture basics of existing motor, the pump housing, intake pipe, outlet pipe and impeller in the existing water pump have been increased, motor comprises housing, stator, rotor, terminal box, the pump housing and housing fix and form a water cavity, intake pipe on the pump housing and outlet pipe communicate with water cavity respectively, the relative the other end that contains permanent magnet rotor one end is fixed with impeller, impeller is in the water cavity, establish the electric region inwall between rotor and the stator, stator is located in the enclosed space of electricity district's inwall and housing formation.
Owing to adopt such scheme, motor combines with the pump housing, rotor combines with impeller, the pump shaft of existing water pump and the output shaft of motor have been omitted, therefore make structure of the present utility model simpler, there is not simultaneously the sealing problem between the pump shaft and the pump housing, thereby solved the sealing problem of existing water pump, reduced maintenance load.In addition, safe in utilization, the reliable performance of the utility model, efficient height.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a sectional view of the present utility model.
Can be added with seal washer 8 between the pump housing 14 and the housing 1 fixes again, form a water cavity 9 between the pump housing 14 and the housing 1 simultaneously, intake pipe 15 on the pump housing and outlet pipe 10 communicate with water cavity 9 respectively, permanent magnet 5 is fixed on rotor one end, its relative the other end is fixed with impeller 11, impeller is in the water cavity, and the rotor 6 ends place of containing impeller can be provided with and prevent the rotor catch 12 of move left and right in the horizontal direction, and catch is connected with spring 13 on being fixed on the pump housing 14.Establish electric region inwall 7 between rotor and the stator, inner wall thickness can be 15-2mm, and inwall can fuse with housing system, and inwall 7 adopts heat-resisting anti-solid plastics or other insulating material to make, heat-resisting requirement be lower than 200 ℃ not modification get final product.The housing 1 and the pump housing can adopt with inwall 7 identical materials and make, and also can adopt other material such as cast iron to make.Stator is located in the enclosed space of electricity district's inwall and housing formation, prevents that the water in the water cavity from entering, and stator is an iron core, is wound with coil 3 on stator iron core, and the terminal box 2 of coil and motor is joined.When power connection terminal box 2, make coil 3 energisings of twining on stator 4 iron cores and produce magnetic field, thereby the rotor 6 that has permanent magnet is rotated, impeller 11 also will rotate, and water from outlet pipe 10 ejections, reaches the effect of water pump by intake pipe 15, water cavity 9.
Claims (3)
1, a kind of Non-axle water pump, include housing, stator, rotor, the terminal box of motor, it is characterized in that also including the pump housing, intake pipe, outlet pipe and impeller, the pump housing and housing fix and form a water cavity, intake pipe on the pump housing and outlet pipe communicate with water cavity respectively, and the relative the other end that contains permanent magnet rotor one end is fixed with impeller, and impeller is in the water cavity, establish the electric region inwall between rotor and the stator, stator is located in the enclosed space of electricity district's inwall and housing formation.
2, Non-axle water pump according to claim 1 is characterized in that being provided with seal washer between the pump housing that fixes and housing.
3, Non-axle water pump according to claim 1 and 2, the rotor tip place that it is characterized in that containing impeller is provided with and prevents the rotor catch of move left and right in the horizontal direction, and catch is connected with spring on being fixed on the pump housing.
