Abstract

The invention discloses a metal magnetic pump plane bearing structure, which comprises a bearing box, a controller and a main body of a magnetic pump. A controller is arranged on one side of the main body of the magnetic pump, and a motor is arranged on one side of the controller. The upper end of the motor is An alarm is provided, one side of the alarm is provided with a rear bearing cover, one side of the rear bearing cover is provided with a bearing box, and several plane bearings are provided inside the bearing box, and the inside of the plane bearing is provided with A drive shaft, and the drive shaft is connected with the motor, a front bearing cover is provided on one side of the drive shaft, an external magnetic rotor is provided on one side of the front bearing cover, and the external magnetic rotor is connected with the drive shaft, the There is a spacer on one side of the outer magnetic rotor, and a heat dissipation pipe is arranged inside the spacer. By setting a plane bearing in the bearing box, the contact length is increased, so that the bearing can obtain high load capacity and High rigidity, and can reduce edge stress, improve service life.

Description

technical field [0001] The invention relates to a plane bearing structure, in particular to a metal magnetic pump plane bearing structure. Background technique [0002] Magnetic pump (also known as magnetic drive pump) is mainly composed of pump head, magnetic drive (magnetic cylinder), motor, base and other parts. The magnetic drive of the magnetic pump is composed of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate through the coupling, the magnetic field can penetrate the air gap and the non-magnetic material isolation sleeve, and drive the inner magnetic rotor connected to the impeller to rotate synchronously, realizing the non-contact synchronous transmission of power, and will easily leak The dynamic seal structure is transformed into a static seal structure with zero leakage. Since the pump shaft and inner magnetic rotor are completely sealed by the pump body and the isolat...
