Specific implementation mode
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram only to show
Meaning mode illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
As shown in Figure 1, a kind of energy saving two stage pump freezes water supply system, including water collector 3, water knockout drum 8 and refrigerator
1,1 water inlet end of refrigerator connects water collector 3 through pipeline, and primary pump 2 is provided on the pipeline between refrigerator 1 and water collector 3, cold
1 water outlet of jelly machine connects water knockout drum 8 through pipeline.
Water inlet pipe connects water collector 3, and outlet pipe connects water knockout drum 8, cooling regulating valve 5, water collector 3 are provided on outlet pipe
It is provided with balance pipe 7 between water knockout drum 8, balance pipe regulating valve 6 is provided on balance pipe 7；The connection two stage pump 4 of water knockout drum 8, two
Grade 4 water outlets of pump connect outlet pipe through pipeline.
Water inlet pipe, outlet pipe, primary pump 2 and two stage pump 4 quantity selected according to the actual quantity of user, each user
A corresponding water inlet pipe, outlet pipe, primary pump 2 and two stage pump 4.
It is provided with first pressure sensor 10 on water collector 3, second pressure sensor 9 is provided on water knockout drum 8；
It is provided with return water temperature sensor 12 on water inlet pipe, supply water temperature sensor 11 is provided on water inlet pipe.
Increase balance pipe regulating valve 6 on balance pipe 7, the lift of primary pump 2, which is set as pressure difference control balance pipe, to be adjusted
The aperture of valve 6, when balance pipe regulating valve 6 is closed, cooling regulating valve 5 is opened, by primary pump 2 directly to user's cooling, flat
