Water back water pump.
Wherein the self-checking device receives the weight from bromine measuring tank and feeds back, the switch feedback from stop valve,
Velocity feedback and pressure leakage detection feedback from metering pump, the frequency feedback from blender, the flow feedback from flowmeter,
The temperature of operation feedback and chilled brine water inlet pipe, chilled brine return pipe and reaction kettle from chilled brine back water pump is anti-
Feedback.
Wherein the self-checking device sends switch command to stop valve to metering pump transmission speed adjustment signal, right
Chilled brine sends start stop command, sends blowing to the external world and reminds.
Further wherein, the chilled brine back water pump can be by long-range and on the spot control.
The utility model has the beneficial effects that:
By device disclosed by the utility model, mitigate labor intensity of workers, safety coefficient is improved, according to tetrabromobisphenol A
Process characteristic, it is practical in conjunction with production, add bromine system, Discrete control, according to the temperature automatic adjustment of reaction kettle by automatically controlling
