Description

Technical Field

[0001] The utility model relates to the field of magnetic pumps, in particular to a dynamic balance adjustment device for a magnetic pump. Background Art

[0002] The magnetic drive centrifugal pump (magnetic pump for short) is a new type of pump that applies the principles of modern magnetic mechanics and uses the magnetic drive of permanent magnets to achieve contactless transmission of torque. A common method of reducing axial force is to connect the balancing baffle to the pump body with bolts. However, the installation accuracy will affect the clearance accuracy between the impeller and the screws. After long-term use, the screws will fall off, rust, or even corrode, which will cause wear or damage to the parts inside the pump.

[0003] To solve the above problems, after searching, an axial self-balancing device for a magnetic pump with the announcement number CN221195474U was found. The article proposes that when the impeller rotates inside the pump body, it will engage with the gear through the tooth groove. Therefore, the impeller will be limited by the gear during rotation, thereby achieving a method of reducing the axial force. In addition, the impeller will be protected by a protective cover during rotation, so the impeller will also reduce a certain amount of wear in the later stage through the protective cover. This solves the common method of reducing axial force by connecting the balancing baffle to the pump body with bolts, but the installation accuracy will affect the gap accuracy between the impeller and the impeller. After long-term use, the screws will fall off, rust or even corrode, which will cause wear or damage to the parts inside the pump.

[0004] Although the above-mentioned balancing device for the magnetic pump can achieve the purpose of reducing the axial force by limiting the impeller by gears when rotating, but when this device is actually used, a protective cover is fixedly installed on the pump body. When it is working, its internal components rotate, causing the outer casing of the device to vibrate. Since there is no supporting structure at the bottom, it is in a suspended state when working, which reduces the stability of the balancing device and easily causes the balancing device to be displaced or deformed under the action of vibration, affecting the normal operation accuracy of the motor.
