[0035] Such as image 3 The trend diagram shown in combination with the auxiliary time curve diagram can judge the suspension of the ash hopper and the damage of the valve. The operation mode after the transformation is mainly based on the material level signal control:
[0036] (1) Under normal circumstances, each conveying unit is automatically programmed to operate according to the set parameters. The process is to start the operation and the feed valve is opened (the conveying tank starts to load ash) --- the material level of the conveying tank reaches the set value or the set ash loading When the time is up---the feed valve is closed---the discharge valve is opened-the intake valve is opened (start conveying)-the pressure of the conveying pipeline drops to the set value---the intake valve is closed (a conveying cycle ends) - go to next loop.
[0037] (2) This program sets two parameter setting windows, which are the setting of the ash level height of the feed material a...
