Embodiment 1

[0044] The following is an introduction to Embodiment 1 of a dual fan output balance adjustment method provided by the present application, see figure 1 , embodiment one includes:

[0045] S101. Obtain a furnace negative pressure process value and a furnace negative pressure target value, and calculate a difference between the furnace negative pressure process value and the furnace negative pressure target value.

[0046] S102. Determine whether the current adjustment mode is a steady-state adjustment mode according to the difference, if yes, go to S103, otherwise go to S104.

[0047] Wherein, when the absolute value of the difference is smaller than the steady-state deviation value, it is determined that the current adjustment mode is a steady-state adjustment mode, otherwise, it is determined that the current adjustment mode is a dynamic adjustment mode.

[0048] S103. Adjust the first fan or the second fan.

[0049] S104. Simultaneously adjust the first fan and the second...

Abstract

The invention discloses a double-fan output balance adjusting method. The method achieves the purpose of automatically adjusting fans on one hand, and avoids the manual adjustment process; and on the other hand, during automatic adjustment, whether the fan is in a steady state or a dynamic state is judged according to the deviation between the process value and the target value, if the fan is in the steady state, only a single fan is adjusted, unnecessary fan adjustment times are reduced, and if the fan is in the dynamic state, two fans are adjusted at the same time, the adjustment speed is increased, and fan equipment safety is guaranteed. In addition, the invention further provides a double-fan output balance adjusting device and equipment, and a readable storage medium. The technical effects of the double-fan output balance adjusting device and equipment and the readable storage medium correspond to the technical effects of the method.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, equipment and readable storage medium for adjusting the output balance of dual blowers. Background technique [0002] The induced draft fan and the blower fan of large and medium-sized boilers usually adopt a dual-fan configuration, that is, 2 sets of induced draft fans and 2 sets of blower fans. Taking the induced draft fan as an example, when the induced draft fan is turned on automatically, in order to ensure the uniform output of the two fans and ensure the flue air volume Evenly, usually two fans are adjusted synchronously, that is, the two fans are adjusted synchronously according to the automatic command of the proportional integral differential module (PID), and the two fans are turned on or off simultaneously. [0003] However, due to the different characteristics of the fans, the output of the fans is not the same when the same opening is a...
