Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pumps, in particular to a vacuum pump cleaning device and a vacuum pump. Background Art

[0002] The magnetic levitation vacuum pump is directly connected by a high-speed permanent magnet synchronous motor and a high-efficiency three-dimensional flow impeller. Its working principle is as follows: air enters the three-dimensional flow impeller directly driven by the magnetic levitation high-speed permanent magnet motor, and is driven by the high-speed rotating impeller to suck air from various suction points of the paper machine production line and discharge it. The inhaled gas is mixed with a large amount of water vapor and pulp. Most of the water vapor and pulp impurities will be filtered out by the steam-water separator, and a small amount of impurities will enter the motor volute and adhere to the inner wall of the collector and the motor fan blades.

[0003] Due to the long-term operation of the vacuum pump and the presence of pulp in the inhaled air, pulp will accumulate on the inner wall of the collector shell and the inner and outer blades of the motor volute. If the pulp accumulation on the blades cannot be judged and cleaned in time, the pulp will easily become thicker and solidify, increasing the difficulty of cleaning and affecting the dynamic balance of the motor blades, thereby affecting the running trajectory of the motor, causing equipment shutdown and affecting production.

[0004] In the prior art, when cleaning the pulp on the vacuum pump blades, the entire production line needs to be stopped, and the bellows, collector and motor volute need to be removed to clean the blades. The on-site operation is difficult and consumes a lot of manpower and material resources. In addition, in the process of disassembling the vacuum pump bellows, collector and motor volute, it is easy to cause damage to the intake temperature sensor and bump the motor blades. The bump of the motor blades can easily affect the dynamic balance of the motor blades, thereby affecting the running trajectory of the motor. In addition, during the reinstallation process, the flange gasket is difficult to install, which affects the sealing of the pipeline, thereby affecting the vacuum degree of the equipment operation.

[0005] In addition, during the installation of the magnetic levitation vacuum pump, foreign objects are easily dropped into the air outlet of the motor volute due to the carelessness of the installers. The motor volute of the magnetic levitation drum vacuum pump is a closed volute. Therefore, after the motor blades are found to be abnormal during debugging, it is difficult to determine what the foreign object is and the specific drop position in the volute. The foreign object can only be removed by removing the bellows, collector and volute as a whole. The on-site operation is difficult, time-consuming and laborious. Moreover, in the process of disassembling the vacuum pump bellows, collector and motor volute, it is easy to cause damage to the intake temperature sensor and bump into the motor blades. The bumping of the motor blades can easily affect the dynamic balance of the motor blades, affect the running trajectory of the motor, and thus affect the normal use of the vacuum pump.

[0006] At the same time, due to the close connection between the volute, collector, bellows and intake pipe, when the vacuum pump motor trajectory is abnormal, it is impossible to quickly check the condition of the motor blades inside and outside the volute to judge the condition of the motor. The internal and external conditions of the motor volute blades can only be observed by removing the bellows, collector and motor volute, which increases the difficulty of on-site fault judgment.
