Novel magnetic drive pump

Abstract

The invention discloses a novel magnetic drive pump. The pump comprises a mounting plate, a motor is fixedly connected to the right side of the top of the mounting plate, a silencing water storage tank is arranged at the left side of the motor, a transmission shaft is movably mounted in the silencing water storage tank through a bearing, and the right end of the transmission shaft is fixedly connected with an output shaft of the motor through a coupler. The left side of the silencing water storage tank is fixedly connected with a shell, and the left side of the surface of the transmission shaft is sleeved with an outer magnetic sleeve. Noise in the shell and external water are absorbed through the silencing water storage tank, meanwhile, the stability of rotary transmission of the outer magnetic sleeve is improved through a stabilizing mechanism, and the operation stability of an electromagnetic pump is improved; and the novel magnetic drive pump solves the problems that when an existing magnetic drive pump operates, due to the fact that the gap between the shell and the outer magnetic sleeve is larger, the magnetic sleeve is unstable in operation and large in abrasion noise, has the advantages of being stable in operation and low in noise, and improves the operation stability and the noise reduction effect of the magnetic drive pump.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a novel magnetic pump. Background technique [0002] The magnetic pump is a kind of chemical process pump that applies the principle of modern magnetic mechanics and uses permanent magnets to realize non-contact indirect transmission. When the motor drives the outer rotor (that is, the outer magnetic steel) assembly to rotate, the magnetic field line passes through the isolation sleeve through the action of the magnetic field to drive the inner rotor (that is, the inner magnetic steel) assembly and the impeller to rotate synchronously, and the medium is completely enclosed in the stationary isolation sleeve. , so as to achieve the purpose of pumping the medium without leakage, and completely solve the shaft seal leakage of the mechanical transmission pump. Strong corrosion performance and other characteristics, its performance has reached the advanced level of similar produc...
