Detailed description of the invention
By reference to the accompanying drawings the utility model is further described below by specific embodiment.
A kind of water-cooling system described in the utility model, as shown in Figures 1 to 3, it is characterized in that: the water inlet of refrigeration unit 1 connects the delivery port of the first water tank 5 by the first water pump 7-1, the delivery port of refrigeration unit 1 connects the first water inlet of heat exchanger 2, first delivery port of heat exchanger 2 connects water knockout drum 3, second water inlet of heat exchanger 2 connects the second water tank 6 by the second water pump 7-2, second delivery port of heat exchanger 2 connects the first water tank 5, second water pump 7-2 connects frequency converter 8, frequency converter 8 connects plc communication system 9, water knockout drum 3 is connected with pressure sensor 3-1, flow proportion valve 3-2 and water valve 3-3, water valve 3-3 connects the first entrance of the second heat exchanger 3, the water inlet of three-tank 14 is connected after the pipeline of the first outlet connection UV lamp socket of the second heat exchanger, the delivery port of three-tank 14 connects water collector 4 by the 3rd water pump 12, the delivery port of water collector 4 connects the second water tank 6.Described heat exchanger 2 is tubular heat exchanger.Temperature sensor 13 is provided with in described three-tank 14.Described plc communication system 9 Bonding pressure sensor 3-1, temperature sensor 13, flow proportion valve 3-2 and frequency converter 8, and plc communication system 9 is by the conputer controlled of touch-screen.
Cold-producing medium builds water circulation and realizes total head work by the first water pump 7-1 by heat exchanger 2 and the first water tank 5 loop.Refrigeration unit 1 set temperature is 13 DEG C.After heat exchanger 2, another loop water temperature is set as 14 DEG C.The water of 14 DEG C by the second water pump 7-2 through heat exchanger 2 to water knockout drum 3, the hydraulic pressure detection sensor signal on water knockout drum 3 sends into the A of PLC
iport, after PLC inter-process, signal controls turning of heat exchanger 2 by the frequency converter of communication module feeding heat exchanger 2 and spends, and by hydraulic pressure control at 3kg/cm
