The utility model principle of work is as follows:
Recovery helium enters vacuum pump, and (vacuum tightness can reach 8 * 10
-2mbar, guarantee that helium recovery rate is 99%), by reclaiming helium valve (recovery time only needs 1s), enter air storage bag, concentration monitor sensor on gas storage air bag can be controlled at 10 ± 2% by concentrations of helium, when concentrations of helium does not reach, can adjust by the time of helium intake valve and air inlet valve the concentration of helium; Air storage bag is successively transferred to air compressor machine by intake valve, pressure switch (detecting the anterior pressure of head) by helium, and head is thrown into helium by the rotation of motor driving rotor high-speed; Then helium enters gas-oil separation groove and carries out gas-oil separation, when the pressure of gas-oil separation groove inside is during less than 6.5bar, charge valve starts to load and makes head start to load, can passing ratio control valve and proportioning controller controlled loading valve work and controlled loading time respectively, by empty water cooler, (empty water cooler helps scatterer cooling by fan to isolated gas, thereby guarantee air outlet temperature) enter gas-holder, practical for equipment; Head is cooling to be realized by oil cooling; the oil that gas-oil separation groove is separated successively enters head by strainer one (impurity screening), relief valve (capable of regulating oil inlet quantity size); head itself has head strainer; oil return arrives oil cooler and (by fan, to oil cooler, dispels the heat after oil strainer two; guarantee oily temperature); when oil temperature is too high; when temperature sensor senses is spent over 100 of oil temperature controller setting to temperature; oil temperature controller is controlled motor and is quit work; guarantee that head is not burned, play safeguard protection effect.
Therefore compared with prior art, the utility model has following beneficial effect:
Head working stability, accurate control can be accomplished in Ge Fa road, therefore guarantee that system pressure is stable, and the rate of recovery is higher, and the actually operating surface rate of recovery of the present utility model can reach 99%, and concentration can precisely be controlled at 10 ± 2%; Head is cooling to be realized by oil cooling, and security is better, can guarantee the long-term steady operation of head; During the insufficient pressure of gas-oil separation groove inside, charge valve can load in time, load precisely and the time shorter, can guarantee that system goes out atmospheric pressure continual and steady.
