Description
[technical field]
The invention relates to a kind of fluid system and implement the device and method of degasification and quantitative fluid injection, this fluid system is made a general reference system any sealing and hydraulic fluid that be filled with certain mass.
[background technology]
Non-condensing gas in the quantitative fluid injection process of various fluid system in the scavenge system is to avoid its negative effect, be the problem that industry is paid attention to, the scope that above-mentioned fluid system is contained comprises large-scale steam boiling system, chemical industry process system, the refrigerating circulation system of technical grade and the small-sized liquid cooling heat radiation system that is used for the electronics cooling always.
Below will be set forth in these fluid systems if retain have non-condensing gas the typical negative effect that may cause and the disappearance of known techniques.
For example: for the closed-cycle system of group's Pu drive fluid or for the refrigerating circulation system of driven compressor fluid, the non-condensing gas that is stranded in group Pu or compressor can make the wheel blade (impeller) of rotation at a high speed that cavitation pitting (cavitations) phenomenon takes place and reduce its due usefulness even cause the damage of group Pu or compressor.
Again for example: in heat biography or cooling system, no matter non-condensing gas is stranded in the heat source side (heater, absorber) of this system or heat sink end (cooling body, radiator) all can cause heat to pass or the obstacle of cooling, the former can cause the unusual intensification of heat source side and make the analgesic ability drop of system, even makes this system damage; The latter can cause the long-pending heat of system because of the decline of heat biography or cooling performance, make the unusual intensification of working fluid and boost, so that when design, must improve the heatproof and the withstand voltage specification of system, can avoid the impaired of system, thus the risk that the globality (integrity) of the manufacturing cost of increase system and raising system is on the hazard.
Again for example: at the assembly of fluid system and the working fluid of pipeline high speed motion, Yi Yin sneaks into non-condensing gas wherein and quickens this fluid system dashed corrosion (flow-induced erosion andcorrosion) phenomenon, thereby this system that makes long-term operation causes the thinning of assembly and pipeline, and the problem of oxidation corrosion, serious threat is to the globality of system.
In addition, having non-condensing gas in the fluid system often causes the fluid concussion and makes system present wild effect; If further having non-condensing gas to infiltrate with pressure reduction or pressure is the instrument that various monitoring system was operated () the pressure signal transfer tube for example: liquid level gauge, flowmeter, differential manometer, pressure gauge etc. of original signal, may cause the distortion of these important instrument signals, thus the risk of this fluid system control module generation misoperation that raises; Because above-mentioned is that the instrument of original signal has been widely used in industrial quarters with pressure reduction or pressure, should prevent making its negative effect and may cause the harm with peripheral staff and environment to system itself.
Exemplify because non-condensing gas retains in many negative effects in the various fluid system by above, be presented at the process that these fluid systems inject the paced work liquid, must develop a reliable apparatus with the interior non-condensing gas function of synchronous scavenge system.
Known techniques is implemented fluid injection for the simple system of a similar cell body, usually need at least two openings to reach, comprise that an inlet is located at the lowermost end of cell body and the top that an exhaust outlet is located at cell body, and utilize gravity or the driving force that adds makes the hydraulic fluid of certain volume be imported by this inlet, simultaneously isopyknic gas is discharged by this exhaust outlet, treat to close above-mentioned inlet and exhaust outlet when this intrasystem hydraulic fluid reaches predetermined storage (inventory), reach the purpose of fluid injection simultaneously and exhaust.
Yet, with regard to practice is used, establish in the bottom establish an exhaust outlet in an inlet and top the practice often because of the factor of the considering of the restriction in space, operation, worker's peace etc. can't one size fits all in any system; Especially for may make the non-condensing gas accumulation in dead angle everywhere than for the complication system, gas removing pipe generally must be arranged at the top at these dead angles, and implement exhaust in fluid injection or after the fluid injection one by one, so inevitable consuming time taking a lot of work, the but thorough interior non-condensing gas of scavenge system; Moreover, in practical application, do not need whole system is filled with hydraulic fluid the real basic demand that is difficult to take into account non-condensing gas in quantitative fluid injection and the effective scavenge system of therefore above-mentioned known techniques usually.
Because known techniques adopts fluid injection can't reach the requirement of non-condensing gas in effective scavenge system in the mode of degasification, and many negative effects of easily deriving, thereby cost is improved and the increase technical difficulty, therefore be necessary known techniques is made improvements.
[summary of the invention]
In view of this, one aspect of the present invention provides a kind of fluid system to carry out the device of effective degasification and fluid injection, this device comprises a vacuum pumps, a fluid injection groove and a connecting piece, this vacuum pumps is used to remove the non-condensing gas in the fluid system, and this fluid injection groove is used for hydraulic fluid ccontaining to be injected.This connecting piece comprises two manifolds and a junction, and this vacuum pumps and fluid injection groove are connected in this two manifold, and utilizes the UNICOM and the shutoff of valve control vacuum pumps and fluid injection groove and connecting piece.The connecting portion of this connecting piece is used for being connected with an opening of this fluid system, and utilizes the UNICOM and the shutoff of valve control connecting piece and this fluid system.
On the other hand, the present invention also provides a kind of fluid system to carry out the method for effective degasification and fluid injection, this method can be summarized as following steps: utilize a vacuum pumps to remove non-condensing gas in this fluid system from an opening of this fluid system earlier, make this fluid system reach predetermined vacuum; Described opening from this fluid system injects hydraulic fluid to this fluid system then; Seal the described opening of this fluid system at last, thereby set up a sealing and fluid system that be filled with the certain mass working fluid.
In to said apparatus and method, adopt the technological means vacuumize fluid injection more earlier, can avoid known techniques in fluid system, to inject after the quantitative working fluid, because of taking into account many negative effects that the non-condensing gas that is stranded in is wherein caused; In addition, this degasification and priming device only need utilize the single opening of any position of being located in this fluid system to reach with being connected of fluid system, therefore this opening has the function of exhaust outlet and inlet concurrently, overcomes known techniques and establishes the shortcoming that an exhaust outlet is established at an inlet and top in the bottom.
