Problems solved by technology
In a relatively harsh and dangerous gas environment, the safety factor is low, and it is likely to cause sudden accidents due to ignition of the traditional contactor contacts during operation
[0006] However, the traditional centrifugal fan cannot realize remote alarm, and the staff cannot know whether there is a problem when the product is running, so that it cannot solve the problem when the product is used immediately, which greatly increases the risk of product use.

Description
technical field [0001] The invention belongs to the field of centrifugal fan safety, and specifically refers to an intelligent control system for a high-penetration safe centrifugal fan. Background technique [0002] In recent years, programmable logic controllers have been widely used due to their many excellent features, and have become standard equipment for industrial control in industrially advanced countries. It is specially designed for industrial control, integrating electrical, instrumentation and control, and is an ideal control device for realizing mechatronics. [0003] Conventional centrifugal blowers, referred to as centrifugal fans, mostly use traditional relay control circuits in their control systems, and a large number of intermediate relays and time relays are used in traditional blower relay control circuits. Failure and accidents are prone to occur due to poor contacts. Due to the extensive use of traditional relays, the control system is bloated and c...
