Evacuation liquid-filling apparatus for capillary of the present invention the capillary tube loop of pressurized-water reactor nuclear power plant reactor core water level gauge system is vacuumized and the concrete steps of filling liquid as follows:
(1) preparation process
Open inlet valve 14, by in aqua storage tank 12, pack into the filling liquid (remove desalt water) of aequum of influent hopper 6.According to the volume of capillary tube loop, calculate the amount of used filling liquid, except that the allowance of necessity, filling liquid loading amount can not be too much, otherwise can prolong the time that filling liquid vacuumizes.The water inlet pipe 11 of will bleeding links to each other with kapillary.
(2) filling liquid vacuumizes in the aqua storage tank
Give vacuum pump 1 power supply, the filling liquid in the aqua storage tank 12 is bled.Do not need to drop into vacuum meter 5 this moment, vacuum meter 5 need not power supply.
Filling liquid has a large amount of bubbles and overflows from water after the beginning of bleeding, and is the boiling shape, and the back bubble that continues to bleed fades away, and up to the degree that bubble collapse be difficult to be differentiated to naked eyes, can think that filling liquid vacuumizes to finish.
Can increase the amount of vaporization of water when reducing, and vacuum pump 1 lubricating oil is sneaked into seriously reduction lubricating efficiency of steam, therefore need regularly change, generally after lubricating oil presents white emulsus, changed lubricating oil because of hydraulic pressure.
Between the oil draining period, for the sake of assurance, close the total valve 3 of bleeding earlier, to vacuum pump 1 outage, change oil again, then after vacuum pump 1 starts, open the total valve 3 of bleeding.
(3) capillary tube loop vacuumizes
Give vacuum pump 1 power supply, on-the-spot capillary tube loop is vacuumized.Whether the lubricating oil that equally also needs to observe vacuum pump changes, and then should give replacing if change.
When vacuum meter 5 indication reaches 10Pa when following, can close the total valve 3 of bleeding, observe vacuum meter 5 readings, if the vacuum tightness decline rate can not meet the demands, then need to check whether have the leakage situation in the capillary tube loop, otherwise need carry out encapsulation process.
When vacuum meter 5 indication reaches 2Pa, and slip is during less than 20Pa/ minute, can think that capillary tube loop vacuumizes to finish.
(4) capillary tube loop topping up
Close Draw off valve 13, tank extraction valve 8, the water inlet stop valve 7 of bleeding; Open ELECTROMAGNETIC VACUUM band air release 2, the total valve 3 of bleeding, vacuum gauge valve 4,, the flowing water Valve 9 of bleeding, tank water intaking valve 10, inlet valve 14.
At this moment, the filling liquid in the aqua storage tank 12 fills in the on-the-spot capillary tube loop under atmospheric pressure.
Can judge system's topping up situation by the hydraulic insulator pointer of observing reactor core water level gauge system, when the hydraulic insulator pointer is slowly got back to the equilibrium position, whole capillary tube loop external and internal pressure unanimity, the water inlet pipe 11 of bleeding reaches the degree of nature diastole, can think that whole topping up process all finishes.
(5) equipment arrangement
After finishing the work of capillary tube loop topping up, remove the water inlet pipe 11 of bleeding, open inlet valve 14 and Draw off valve 13, the filling liquid in the aqua storage tank 12 is drained.
The performance index of apparatus of the present invention: exhaust capacity 4L/S; Vacuum tightness＜1Pa; Slip＜10Pa/ branch; Filling amount〉3L; Vacuum unit of display Torr, Pa, mbar; Working power 220VAC ± 15%2A; Physical dimension 1050 * 500 * 1635 (wide * dark * high mm); Weight 50Kg.
