When the real-time density is lower

When the real-time density is lower than the target density, adjust according to the following three situations: lower than not much, and the liquid level of the qualified medium barrel is higher, when the water replenishing valve in front of the pump and the water adding valve in the barrel can be completed by reducing the water replenishing valve in front of the pump, if the water replenishing valve in front of the pump is closed, adjust by reducing the water adding valve in the barrel; lower than many, and the liquid level of the qualified medium barrel is higher, and the water level in front of the pump is higher When the matching between the make-up valve and the water adding valve in the barrel can not be completed, the shunting volume of the shunting box must be increased to realize the regulation; when it is lower than many and the liquid level of the qualified medium barrel is lower, which affects the separation pressure, the automatic make-up system must be started to make-up by adding concentrated medium to the qualified medium barrel at this time; after the proper liquid level of Di] n, the make-up valve in front of the pump, the water adding valve in the barrel and the shunting matching shall be used To achieve adjustment.
