Description

[0002] A turbine vacuum pump is a device that uses a high-speed rotating rotor to form a volume change in the pump chamber to remove gas and steam. When the rotor rotates eccentrically, a low-pressure area is formed at the air inlet, thereby sucking in the gas. As the gas is brought to the vicinity of the exhaust port, the kinetic energy of the gas is converted into pressure energy due to the reduction in speed, which increases the gas pressure and eventually discharges the pump out of the exhaust port to achieve the required vacuum degree. It is widely used in the fields of electronics, aerospace, and chemical industry. It can be used to remove gas and steam, improve the environment, or make the equipment reach the required vacuum degree. During the operation of the turbine vacuum pump, the outer wall of the rotor rubs and collides with the gas in the pump body, causing impurities and particulate matter in the gas to adhere to the outer wall of the rotor and gradually form scars. In the prior art, the scars of the turbine vacuum pump rotor are removed by high-pressure flushing, which takes a long time and has certain flushing blind spots, resulting in incomplete cleaning and easy residues, which affects the performance of the turbine vacuum pump and requires a high maintenance frequency.
