The utility model content
The utility model technical problem to be solved provides a kind of refining plant that can solve the cooling pure water of high-power transmission apparatus because of the too high recirculated cooling water that can't run well of electric conductivity.
The technical scheme that solves the problems of the technologies described above is:
A kind of refining plant of recirculated cooling water; It is made up of water pump, water tank, main ion interchanger, auxilliary ion-exchanger, resistance value detector, manually-operated gate, motorized valve; On the outlet conduit of water tank manually-operated gate is installed; Manually-operated gate water outlet pipeline is connected to pump motor, main ion interchanger, auxilliary ion-exchanger, resistance value detector and water outlet motorized valve successively, and the water outlet pipeline that the water outlet motorized valve connects is connected with the frequency transformer pure water cooler.
The refining plant of above-mentioned recirculated cooling water increases a relay K in the frequency transformer cabinet, the trip switch of relay K is connected with the output signal of DO template in the frequency transformer cabinet, and the normally open contact K-1 of relay K is connected in the startup loop of pump motor.
The refining plant of above-mentioned recirculated cooling water, said water tank have two water inlets, and the water outlet pipeline that one of them water inlet is connected with the water outlet motorized valve is connected.
The utility model can be discharged the whole Chen Shui in the frequency transformer pure water cooler, and can wash repeatedly inner circulating water pipeline, has solved internal recycle water and has discharged not thoroughly, influences problems such as water quality, inner-walls of duct residue; The utility model can also be made pure water again, guarantees the pure water quality; Detect through frequency transformer self when moving automatically, when electric conductivity is higher than set(ting)value, can this device is sealed in the pure water circulation loop and start pump motor, make the refining plant operation through relay K.
