In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic flow sheet of the method for filling used in the prior art;
The schematic flow sheet of the method for filling that Fig. 2 provides for the embodiment of the invention.
The specific embodiment
The invention discloses a kind of method for filling and a kind of perfusion equipment, to realize the accurately purpose of perfusion.
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
See also Fig. 2, the schematic flow sheet of the method for filling that Fig. 2 provides for the embodiment of the invention.
The method for filling that the embodiment of the invention provides may further comprise the steps:
Steps A: by the first flow meter total amount of the liquid dielectric that flows out is carried out the metering first time from original container, obtain the first metering result;
Step B: afterwards, by the check gauging device total amount of the liquid dielectric of the process metering first time is carried out the metering second time, obtain the second metering result, and will be stored in the intermediate receptacle through the liquid dielectric after measuring the second time;
Step C: the first metering result and second is measured the result compare, obtain the first difference, judge that this first difference is whether within the first error allowed band, if, then allow the liquid dielectric in the intermediate receptacle to inject target container, otherwise, this time perfusion stopped.
Need to prove at this, so-called the first error allowed band is the data scope for the accuracy of judging gauging device that technical personnel sets up on their own, this the first error allowed band concrete regulation the first metering result measure the tolerance interval of result's difference with second, namely when the first metering result and the second metering result's difference exceeds this scope, can judge the gauging device existing problems in the perfusion equipment.
Can find out from technique scheme, method for filling provided by the invention is in filling process, the liquid dielectric that is pouring into has been carried out twice metering, and directly be not filled into target device through the liquid dielectric after for the second time metering, but be stored in the intermediate receptacle, afterwards, result with twice metering compares again, if find that the result of twice metering is also inconsistent, namely twice metering result's difference has exceeded the first error allowed band, then technical personnel can determine that the gauging device that uses in this filling process is wrong, need to interrupt this time perfusion, and the gauging device that more renews comes the liquid dielectric in the filling process is measured, otherwise, can continue liquid dielectric is filled in the target device.Thereby as seen, in the filling process of method for filling provided by the invention, can avoid to guarantee to pour into result's accuracy and particularity because flow counter is measured the coarse perfusion defective of perfusion that error brings.
In the present embodiment, step C is specially: by weighing-appliance the total amount of liquid dielectric is carried out the metering second time, obtain the second metering result, and stored measuring for the second time liquid dielectric later by weighing-appliance.Yi Zhi in this embodiment, when comparing, need to be converted into volume with the second metering result and the first metering result with the second metering result, measures the result and compares with first again, thereby obtain the first difference.
In actual filling process, mostly can adopt outlet pump to come to provide perfusion power for liquid dielectric, for example, at filling process at first, by the first row oil pump with liquid dielectric from the original containers such as oil drum with its discharge, the liquid dielectric of discharging flows through the first flow meter again and measures, thereby begins to carry out filling process; Afterwards, after weighing-appliance stores liquid dielectric, when proceeding to pour into again, need the second row oil pump that liquid dielectric is discharged in weighing-appliance, proceed again perfusion.Therefore, in order further to optimize technique scheme, step C is specially:
Step C1: the first metering result and the second metering result are compared, obtain the first difference, judge the first difference whether within the first error allowed band, if, then carry out step C2, otherwise, stop this time pouring into;
Step C2: the total amount of the liquid dielectric in the middle container (this intermediate receptacle is weighing-appliance in the present embodiment) is measured for the third time by the second flow counter, obtain the 3rd metering result, and allow the liquid dielectric in the intermediate receptacle to inject target container;
Step C3: the 3rd metering result and default total amount are compared, obtain the second difference, and judge whether the second difference exceeds the second error allowed band.
Need to prove at this, so-called the second error allowed band is the number range for the particularity of judging final perfusion result that technical personnel sets up on their own, this the second error allowed band imbody the perfusion error tolerance interval, namely when the difference (namely pouring into error amount) that contrasts gained by the 3rd metering result and default total amount when exceeding this number range, can judge that this time to pour into accuracy rate lower.
As seen, in the filling process of method for filling provided by the invention, also after the intermediate receptacle (being weighing-appliance herein) of perfusion equipment stores liquid dielectric, before liquid dielectric injects target device, carried out for the third time metering, and this metering result is contrasted as actual groundwater increment and default total amount, the second difference that obtains is the error amount of this filling process, thereby the staff can judge by this error amount the accuracy rate of this filling process.Thereby, compare with the technical scheme that default total amount compares as actual groundwater increment with making the second metering result, present embodiment has been avoided pouring into the larger shortcoming of resultant error owing to the metering result who brings than lossy that liquid dielectric exists with reality in storage process and second row oil pump oil extraction process.
But, those skilled in the art are understood that easily, the total amount of liquid dielectric is carried out for the second time check gauging device of metering, and the intermediate receptacle that in perfusion equipment, liquid dielectric is stored, be not limited in weighing-appliance and realize for the second time metering and the purpose that stores.For example, can also be to carry out the metering second time by the 3rd flow counter, to be stored in through the liquid dielectric of for the second time metering more afterwards one with fuel tank that the 3rd flow counter and second row oil pump communicate respectively in, the first metering result's that the 3rd metering result and the first flow instrumentation that records when the 3rd flow counter gets difference is then proceeded the liquid dielectric in this fuel tank to pour in the first error allowed band the time.Therefore, the present invention does not do restriction to the specific implementation form that is used in the perfusion equipment realizing the check gauging device of for the second time metering and being used for the intermediate receptacle of storage liquid body medium.
Equally, those skilled in the art understand easily, the perfusion equipment that method for filling provided by the invention adopts might not comprise outlet pump, that is to say, is not limited to the use outlet pump for the liquid dielectric in the filling process provides the implementation of perfusion power.For example, when the medium pressure liquid that pours into when needs is higher, not need outlet pump that perfusion power is provided, such as, the placement location in liquid dielectric source is higher, and the target device placement location that the needs that link to each other with perfusion equipment pour into is when low, and the perfusion power of liquid dielectric is provided by gravity, at this moment, can be without outlet pump.Therefore, those skilled in the art are understood that easily, use outlet pump that perfusion power is provided in the perfusion equipment, are a kind of preferred versions that technical personnel is selected as the case may be, and therefore, the present invention does not do restriction to this.
According to above-mentioned method for filling, the present invention also provides a kind of perfusion equipment, and this perfusion equipment comprises first row oil pump, first flow meter, weighing-appliance, second row oil pump and the second flow counter that is cascaded successively.Wherein, the first row oil pump communicates with original container, for filling process provides power; The first flow meter links to each other with the first row oil pump, is used for the volume of the liquid dielectric of metering first row oil pump discharge; Weighing-appliance links to each other with the first flow meter, is used for the storage liquid body medium, and liquid dielectric is carried out weight metering; The second row oil pump is used to the liquid dielectric that is stored in the weighing-appliance that perfusion power is provided, to proceed perfusion; Connect the second flow counter after the second row oil pump, the other end of the second flow counter is used for linking to each other with target device, and this second flow counter is carried out volume measurement to the liquid dielectric that is pouring into.
In this filling process, liquid dielectric is stored in the weighing-appliance after through twice metering, technical personnel is converted into volume with the second metering result of the liquid dielectric that weighing-appliance records, whether the first metering result who again this volume data and first flow instrumentation is got compares, accurate to the metering of liquid dielectric to judge; If accurately, then by the liquid dielectric in the second row oil pump discharge weighing-appliance, make its 3rd flow counter of flowing through inject afterwards the target device that need to pour into, otherwise, change or keep in repair for the part that goes wrong in the perfusion equipment, more again perfusion; After the 3rd flow counter is measured liquid dielectric, the 3rd metering result that technical personnel need to record the 3rd flow counter pours into the result as reality, this actual perfusion result is compared with the default total amount of planning to pour in target device, the difference that obtains is the error amount of this filling process, thereby judge this time accuracy rate of perfusion, and can determine to finish perfusion according to the accuracy rate of this perfusion, perhaps again perfusion (error amount is larger, and not in the situation in the second error allowed band).
In order further to optimize technique scheme, the perfusion equipment that the embodiment of the invention provides also comprises control system, and this control system comprises typing unit, the first calculating unit, the second calculating unit and annunciator.
Wherein, the typing unit is used for the 3rd metering result that the first metering result that default total amount, the first error allowed band, the second error allowed band, the density of liquid dielectric, the first flow instrumentation of the liquid dielectric that the typing target device need to inject get, the second metering result that weighing-appliance records and the second flow measurement get; The first calculating unit is converted into volume with the second metering result, compare with the first metering result again, obtain the first difference, judge that again the first difference is whether within the first error allowed band, if, then allow the liquid dielectric in the intermediate receptacle to inject target container, no by this time perfusion of control system control perfusion equipment termination, perhaps send information by control system, the prompting technical personnel stops this time perfusion; The second calculating unit compares the 3rd metering result and default total amount, obtains the second difference, judges whether the second difference exceeds the second error allowed band again; When the first difference exceeded the first error allowed band, annunciator was reported to the police, and during the second error allowed band, annunciator is also reported to the police when the second difference exceeds.Thereby data and alarm that technical personnel can provide by control system are judged the perfusion situation of this filling process.
Yi Zhi, obtain the second metering result when by weighing-appliance the total amount of the liquid dielectric of the process metering first time being carried out the metering second time, and by weighing-appliance when storing through the liquid dielectric after for the second time metering, read the density of liquid dielectric by control system, the first metering result and the second metering result, and with second the metering result be converted into volume, compare with the first metering result afterwards, obtain the first difference, control system judges that the first difference is whether within the first error allowed band, if, then allow the liquid dielectric in the intermediate receptacle to inject target container, otherwise, control system is reported to the police, and stops this time perfusion.
Those skilled in the art are understood that easily, typing unit in the control system can be the result of a measurement that control system reads first flow meter, weighing-appliance and the second flow counter automatically, also can be by manually reading, the metering that will read again as a result input control system be read by the typing unit.
Yi Zhi, method for filling provided by the invention and perfusion equipment can be applicable in the filling process in multiple technologies field, for example, the perfusion of gasoline in the automotive field, this moment, liquid dielectric was gasoline; Perhaps, the perfusion of refrigerant oil in the air-conditioning unit, at this moment, liquid dielectric is refrigerant oil.But application of the present invention is not limited to this, so long as relate to the field of accurate perfusion, all can use method for filling and perfusion equipment that the embodiment of the invention provides, and therefore, the present invention does not do restriction to technical field.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
