Problems solved by technology

[0002] When the high-speed turbo vacuum pump is used in the papermaking industry, due to the production sequence of the paper machine, it is necessary to turn on the high-speed turbo vacuum pump when the paper machine does not add production raw materials. The flat vacuum pump is idling and cannot be opened normally; it is also possible that due to human factors, the pipe network of the paper machine system is completely closed, causing the high-speed turbo vacuum pump to hold pressure, surge and even damage the impeller of the high-speed turbo vacuum pump

Abstract

The invention relates to the field of vacuum pump control, and particularly relates to a startup control method of a high-speed turbine vacuum pump and a vacuumizing system. The startup control method of the high-speed turbine vacuum pump comprises the following steps that S1, the high-speed turbine vacuum pump is controlled to be started up; S2, the high-speed turbine vacuum pump is controlled to increase the speed; S3, a control module judges the vacuum degree of an air inlet of the high-speed turbine vacuum pump and the preset vacuum degree, if the vacuum degree is equal to the preset vacuum degree, the first startup rotating speed is kept, if the vacuum degree is larger than the preset vacuum degree, the step S4 is executed, and if the vacuum degree is smaller than the preset vacuum degree, the step S5 is executed; S4, the high-speed turbine vacuum pump is controlled to decrease the speed till the requirement of the preset vacuum degree is met; and S5, the input current of the high-speed turbine vacuum pump is controlled to be increased till the input current is the rated current of the high-speed turbine vacuum pump. According to the startup control method of the high-speed turbine vacuum pump and the vacuumizing system, smooth startup of the high-speed turbine vacuum pump can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of vacuum pump control, in particular to a start-up control method and a vacuum pumping system of a high-speed turbo vacuum pump. Background technique [0002] When the high-speed turbo vacuum pump is used in the papermaking industry, due to the production sequence of the paper machine, it is necessary to turn on the high-speed turbo vacuum pump when the paper machine does not add production raw materials. The flat vacuum pump is idling and cannot be opened normally; it is also possible that due to human factors, the pipe network of the paper machine system is completely closed, causing the high-speed turbo vacuum pump to hold pressure, surge and even damage the impeller of the high-speed turbo vacuum pump. [0003] Therefore, there is a need for a high-speed turbo vacuum pump start-up control method and a vacuum system to solve the above technical problems. Contents of the invention [0004] The object o...
