Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic levitation turbine vacuum pumps, in particular to a self-cooling mechanism of a magnetic levitation turbine vacuum pump. Background Art

[0002] The magnetic levitation turbine vacuum pump is a high-performance vacuum pump based on the turbine principle and magnetic levitation technology. It uses magnetic levitation bearing technology, high-speed permanent magnet motor technology, high-frequency vector frequency conversion technology and high-efficiency fluid machinery technology to achieve contactless and frictionless operation. It has the characteristics of high efficiency, energy saving and green environmental protection.

[0003] A magnetic levitation turbine vacuum pump generates a large amount of heat during operation. If it is not cooled, the temperature of the pump body will rise, which may cause the performance of the equipment to decline or even damage. The cooling mechanism can ensure that the magnetic levitation turbine vacuum pump can still maintain efficient operation in a high-temperature environment, reducing the efficiency reduction and increased failure rate caused by overheating. The utility model with authorization announcement number CN218542636U discloses a two-stage magnetic levitation turbine vacuum pump cooling device, including a magnetic levitation vacuum pump motor, an external fan isolation box fixedly installed above the magnetic levitation vacuum pump motor, a filter box fixedly installed above the external fan isolation box, an external fan installed in the external fan isolation box, an air inlet of the external fan connected to the filter box, and an air outlet of the external fan connected to the interior of the magnetic levitation vacuum pump motor.

To address this problem, we provide a self-cooling mechanism for a magnetic levitation turbine vacuum pump. Utility Model Content
