The course of work of the present invention is as follows,
For the first time in use, negative pressure water tank 2 is filled into water, by the top vent ball valve 221 of negative pressure water tank 2 and water filling when pouring water
Ball valve 231 is opened, and water injection pipe 23 is used for water filling, and blast pipe 22 is used to discharge gas in negative pressure water tank 2, fills to close after water and tries one's best
The vacuum of negative pressure water tank 2 is kept, sets and is opened respectively at 3 meters, 2 meters and 1 meter, and by control cabinet automatic/hand at senior middle school's low water level
" automatic " position is got in pass.When water level in water pool reaches the high water level of setting, water level controller SK obtains electric, auxiliary reclay coil
KA1 obtains electric, auxiliary reclay normally opened contact KA1 closures, and red light HL1 is bright, while the automatic running of water pump 3.Therefore in preceding water tank
Water is filled, radiator drain 21 is higher than pump outlet, so water pump 3 is operated immediately, the water in negative pressure water tank 2 is discharged.And
As the water level of negative pressure water tank 2 is gradually reduced, the vacuum in negative pressure water tank 2 also can be increasing, when water level is down to certain position
Afterwards (position necessarily be greater than 21 mouthfuls of radiator drain), the water in cesspool 4 is pressed into through suction hose 1 under atmospheric pressure
In negative pressure water tank 2, continuously Mine System treating stations are expelled to through water pump 3.As water pump is constantly run, water level in water pool gradually drops
It is low, (it is that water tank is in full water state when ensureing that water pump stops that low water level, which is set), water level control when being down to the low water level of setting
Device SK dead electricity, normally opened contact closure, auxiliary reclay coil KA2 obtains electric, auxiliary reclay normally opened contact KA1 closures, normally closed to touch
Point KA1 disconnects, and red light HL1 is bright, and water pump 3 is automatically stopped.When water level rises to high water level again, water pump 3 is just grasped without personnel
Make Auto-drainage, detect, stop, so circulation.
As shown in figure 3, there are problems in raw sewage pond drainage system, it is engineered after, abandoned bottom valve 5, without bottom valve
Self-draining arrangement is simple, and fitment material cost is low, boiler room effluent cycle is more stablized using system operation, reliably.
Not only reduce the input of personnel and Master Cost, it is thus also avoided that water resource waste, improve site environment, reach economic reality
Lowered consumption with, section branch, the purposes of energy-conserving and environment-protective.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
