[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

The present invention relates to the field of vacuum pump control, in particular to a start-up control method of a high-speed turbo vacuum pump and a vacuum pumping system. The start-up control method of a high-speed turbo vacuum pump includes the following steps: S1. Speed up the turbo vacuum pump; S3, the control module judges the vacuum degree of the air inlet of the high-speed turbo vacuum pump and the size of the preset vacuum degree, if equal, then maintain the first starting speed, if greater than the preset vacuum degree, then enter the step S4, if it is less than the preset vacuum degree, go to step S5; S4, control the high-speed turbo vacuum pump to slow down until the preset vacuum degree is met; S5, control the input current of the high-speed turbo vacuum pump to increase until the input current is high speed The rated current of the turbo vacuum pump. The invention can ensure the smooth start-up of the high-speed turbo vacuum pump.
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.
