Problems solved by technology

[0003] However, the axial space occupied by the aforementioned two gaps 1311 and 1151 makes the volume of the fluid pump 1 unable to be reduced.
In addition, the friction between the fluid and the outer surfaces of the front and rear cover plates 1221, 1222 of the impeller 122 will cause disc loss, and the diameters of the existing front cover plate 1221 and the rear cover plate 1222 are larger than the diameter of the magnet 121, the The larger the diameter of the impeller 122, the greater the loss of the disc, resulting in low rotational speed of the rotor 12, so the operating efficiency of the rotor 12 is poor

Abstract

The invention provides a pump body rotor and a fluid pump. The pump body rotor comprises a bearing, a magnet and an impeller. The impeller is provided with a front cover plate, a rear cover plate andmultiple fan blades arranged between the front cover plate and the rear cover plate. The rear cover plate is annularly arranged outside the bearing and is arranged on the magnet. The magnet, the frontcover plate and the rear cover plate have the same diameter and are overlapped in the axial direction.

Description

technical field [0001] The invention relates to the field of pumps, in particular to a pump body rotor and a fluid pump thereof. Background technique [0002] Fluid pump is a device that drives fluid to speed up circulation, such as figure 1 The existing fluid pump 1 shown has a seat body 10 with a groove 11 extending downward, the groove 11 has a side wall 111 and a bottom wall 112 to define a first chamber 113, the top of the side wall 111 faces A platform 115 is extended outwardly, a rotor 12 is arranged in the first chamber 113, and an upper cover 13 is correspondingly covered with the seat 10 to close the first chamber 113. The rotor 12 has an impeller 122, and the impeller 122 has A front cover 1221 and a rear cover 1222, the upper cover 13 has a spacer 131, the spacer 131 is arranged on the base 10 and closes the front cover 1221, the front cover 1221 and the rear cover The diameter of 1222 is larger than the diameter of this magnet 121, in order to prevent this imp...
