Description
Technical Field
The utility model relates to a water pump technical field, in particular to duct formula axial-flow pump.
Background
Water pumps are machines that deliver or pressurize a liquid. It transfers the mechanical energy of prime mover or other external energy to liquid to increase the energy of liquid, and is mainly used to transfer liquid including water, oil, acid-base liquid, emulsion, suspoemulsion and liquid metal.
At present, most water pumps all drive the blade rotation of water pump through external power device, but when using in some narrow and small spaces, because the device is bulky, put and all can bring very big degree of difficulty with the installation.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a duct formula axial-flow pump to it is too big to solve current water pump and power device volume, the inconvenient problem of putting and installing.
In order to solve the technical problem, the utility model provides a ducted axial-flow pump, which comprises a base, a water inlet connecting flange and a water outlet connecting flange, wherein the water inlet connecting flange and the water outlet connecting flange are respectively and fixedly connected with two ends of the base;
a stator coil is arranged in the base and is in interference fit with the base;
and a permanent magnet rotor impeller is arranged in the stator coil.
Optionally, the permanent magnet rotor impeller includes a permanent magnet, a blade, and a blade seat, and the permanent magnet is fixedly connected to the top end of the blade.
Optionally, the end of the permanent magnet rotor impeller is connected with a guide vane bearing body for supporting the permanent magnet rotor impeller.
Optionally, the guide vane bearing body is connected with the water outlet connecting flange through a bracket.
Optionally, a junction box is arranged outside the base.

Drawings
Fig. 1 is an overall structure schematic diagram of a ducted axial-flow pump provided by the present invention.
Detailed Description
The ducted axial-flow pump according to the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.
The utility model provides a ducted axial-flow pump, the structure of which is shown in figure 1, comprising a base 1, a water inlet connecting flange 2 and a water outlet connecting flange 3, wherein the water inlet connecting flange 2 and the water outlet connecting flange 3 are respectively fixedly connected with the two ends of the base 1 and are used for connecting a water inlet pipe and a water outlet pipe; a stator coil 4 is arranged in the base 1, and the stator coil 4 is in interference fit with the base 1; a permanent magnet rotor impeller 5 is arranged in the stator coil 4, the permanent magnet rotor impeller 5 comprises a permanent magnet 51, a blade 52 and a blade seat 53, and the permanent magnet 51 is fixedly connected to the top end of the blade 52; the center axes of the stator coil 4, the permanent magnet 51, and the vane 52 are coincident with each other.
Specifically, the end of the permanent magnet rotor impeller 5 is connected with a guide vane bearing body 6 for supporting the permanent magnet rotor impeller 5, because the permanent magnet rotor impeller 5 is not in contact with the stator coil 4, when the stator coil is not electrified, the guide vane bearing body 6 axially supports the permanent magnet rotor impeller 5, and the guide vane bearing body 6 is a sealing structure, so that the damage caused by water entering the internal bearing can be effectively prevented; and a junction box 8 is arranged outside the base 1, and a lead is connected in the junction box and is used for electrifying the stator coil 4.
Specifically, please continue to refer to fig. 1, first connect the pipeline to the water inlet connection flange 2 and the water outlet connection flange 3, connect the conducting wire to the junction box 8, and energize, the stator coil 4 generates the magnetic field, the permanent magnet 51 drives the blade 52 to rotate under the action of the magnetic field, the blade 52 transmits the water flow from the water inlet to the water outlet, after that, the power is off, the guide vane bearing body 6 supports the permanent magnet rotor impeller 5, so that it is fixed in the air, and the stator coil 4 is prevented from being damaged by impact.
The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
