Magnetically-driven submerged liquid chlorine pump

Abstract

The invention provides a magnetically-driven submerged liquid chlorine pump. The pump comprises an electric motor, an outer magnetic cylinder driven by the electric motor, an inner magnetic cylinder in magnetic coupling with the outer magnetic cylinder, a liquid chlorine pump output shaft connected with the inner magnetic cylinder and a bearing support for erecting the liquid chlorine pump output shaft. An impeller is connected with the end, opposite to the inner magnetic cylinder, of the liquid chlorine pump output shaft, and a plurality of layers of distance sleeves are arranged between the inner magnetic cylinder and the outer magnetic cylinder and are fixed to the bearing support through a connecting plate; a gap exists between the adjacent distance sleeves, and closed vacuum space is formed between the adjacent distance sleeves; the connecting plate is fixedly connected with a liquid leakage alarming apparatus communicated with the vacuum space; and the distance sleeves are non-metal distance sleeves. According to the technical scheme, heat generated by the magnetic vortex is avoided; liquid lubricating and cooling are not needed; the phenomenon that media pollute the inner magnetic cylinder and the external environment is completely eradicated; and the service life of the inner magnetic cylinder, the outer magnetic cylinder and the distance sleeves is prolonged.

Description

technical field [0001] The invention relates to the field of liquid chlorine pumps, in particular to a magnetically driven submerged liquid chlorine pump. Background technique [0002] The inner magnetic cylinder and the outer magnetic cylinder of the traditional magnetic drive liquid chlorine pump rotate, but the metal isolation sleeve does not rotate. The metal isolation sleeve will generate a magnetic eddy current and also generate a lot of heat, and the temperature will continue to rise, which will easily burn the parts and cause internal and external damage. To demagnetize the magnetic cylinder, liquid chlorine must be used to lubricate the bearings and cool the spacer and the magnetic cylinder. However, the inner magnetic cylinder is easy to attract rust and other debris in the liquid chlorine, which is easy to cause damage to the inner magnetic cylinder and the isolation sleeve. Once the isolation sleeve and the inner magnetic cylinder are damaged, the medium will lea...
