Described control unit is arranged on the top of frame, is provided with the control panel 53 of control unit in frame upper end.
Level pressure operating process:
Pressure of return water Sensor monitoring reclaimed water system pressure, when reclaimed water system pressure is increased to the setting pressure upper limit (being generally setting value+0.2bar), unloading pressure control valve door is opened by control unit, the water raised causing system pressure is stored in normal pressure tank, the air bag volume expansion of normal pressure tank, maintains system pressure constant.If water level superelevation in normal pressure tank in pressure leak process, control unit gives electronic drain valve signal, and electronic drain valve is opened, and normal pressure tank starts to sluice until tank body water level is down to safety value.
When reclaimed water system pressure drop is to setting pressure lower limit (being generally setting value-0.2bar), control unit starts small pump letter, water in normal pressure tank is mended in reclaimed water system by small pump, and when the pressure of reclaimed water system reaches setting value, small pump quits work.
When the change of reclaimed water system pressure is less (being less than ± 0.2bar), the expansion drum being arranged on exit of pump plays the effect of voltage stabilizing, and reclaimed water system Pressure behaviour is balanced.
Bleeding process:
Because normal pressure tank communicates with air, in normal pressure tank, gas solubility is much smaller than gas solubility in reclaimed water system, therefore when circulating water flow is through normal pressure tank, automatically the gas in water can be separated out, discharge through automatic air valve, meanwhile, normal pressure tank is also used to the device of storage and regulating system allowance for expansion.
This part unsaturated water with high absorption character is noted back reclaimed water system again, can make it balance by the gas again in absorption system.This device repeats such circulation, and the free gas in water and dissolved gas are just excluded in this circulation.
Water-refilling operation process:
LOAD CELLS monitoring tank body water level conditions bottom normal pressure tank, and measured value is fed back to control unit, when normal pressure tank water level is lower than setting value, control unit sends signal and opens moisturizing motor operated valve, and external source is to normal pressure tank moisturizing.
In moisturizing process, the water entering normal pressure tank is first exhausted by reducing pressure, then just can by benefit in system pipeline.
Normal pressure tank is primarily of air bag, tank body and automatic air valve composition, and tank interior communicates with air.During use, water does not contact completely with inner tank wall, so stopped to get rusty and the secondary pollution of water quality.The recirculated water of high pressure enters in air bag and becomes normal pressure, the gas evolution in water.
