Abstract
The utility model relates to a cone structure for the rotor end part of a shielding motor as well as that of an electric pump. The cone structure comprises a shaft, a rotor shielding plate, a copper rod rotor and a rotor shielding sleeve, wherein the copper rod rotor and the rotor shielding plate are mounted on the shaft, the rotor shielding sleeve is mounted in the middle of the rotor shielding plate and the copper rod rotor, and the rotor shielding plate is conical. The structure is simple in structure and reasonable in design; and the structure for the rotor end part of the shielding motor as well as that of the electric pump is changed, so that the liquid circulation channel is effectively changed, the cooling effect of the motor and the lubricating effect of a rubbing pair are improved, the internal work conditions of the shielding motor as well as the electric pump is improved, and the performance of the motor as well as that of the electric pump is improved, and the service life of the motor as well as that of the electric pump is prolonged.
Description
Technical field:
The utility model relates to a kind of shield electric machine electric pump rotor tip cone structure.
Background technology:
Current shield electric machine electric pump rotor terminal structure is a column structure, the end does not have the conical surface, the shield electric machine internal liquid circulates in two ends of rotor and becomes the big and poor circulation path that diminishes twice by meeting suddenly because of process circulation cross section, cause the circulation of liquid advection turbulent flow and circulation resistance to occur, cause circulating effect poor, cause the friction lubricating effect to descend, the heat that motor itself produces can't be taken away fast, has influenced the performance and the useful life of motor electric pump.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned shortcoming, a kind of shield electric machine electric pump rotor tip cone structure is provided, it has mainly solved shield electric machine electric pump rotor terminal structure and has designed unreasonable, cause circulating effect poor, the heat of motor itself can't be taken away fast, influences problems such as the performance of motor electric pump and useful life.
The purpose of this utility model is achieved in that shield electric machine electric pump rotor tip cone structure is made of: axle, rotor screen board, copper bar rotor, rotor shielding sleeve.Copper bar rotor and rotor screen board are installed on the axle by heating, and rotor shielding sleeve is equipped with in the rotor screen board and the copper bar rotor outside, and the rotor screen board is conical, and rotor shielding sleeve is coated on the rotor screen board conical surface, the long 8-10mm of the conical surface, tapering 8-10 °.
This product structure is simple, reasonable in design, owing to changed shield electric machine electric pump rotor terminal structure, effectively changed liquid circulation channel, the cooling effect of motor and the lubricant effect of friction pair have been improved, improve the internal work condition of shield electric machine and electric pump, improved the performance and the useful life of motor electric pump.
