Reasonable in design of the present invention, invention employing elder generation with in little recorder jar of liquid delivery pump input, because the Capacity Ratio of recorder jar is less, drops it off the cold-producing medium of big stock bottle on the little electronic scale of range, electronic scale just can adopt the electronic scale of Libra level, accuracy will be very high, and it is just very little to fill error, can satisfy the job requirement of the following charging amount of 50g, automaticity height of the present invention, cost is low, and price is cheap more than flowmeter, long service life.
Description of drawings
Accompanying drawing is a structure principle chart of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
In conjunction with the accompanying drawings, a kind of cold-producing medium weight metering formula automatically fills machine, comprises housing 1, and surface of shell is provided with the liquid phase interface 3 gentle interfaces 4 that are connected with cold-producing medium stock bottle 2, and surface of shell also is provided with the filled mouth 6 that fills cold-producing medium to refrigeration plant 5.
Be provided with the refrigerant charging equipment B in the housing body.
The refrigerant charging equipment B comprises recorder jar 21, weigher 22, heater 23, recorder jar 21 is placed on the weigher 22 and weighs, cold-producing medium in the heater 23 heating recorder jars 21, recorder jar 21 is provided with gas phase interface 24, liquid phase interface 25 and cold-producing medium output interface 26, recorder jar 21 gas phase interfaces 24 communicate with the gas phase interface 4 of surface of shell and be provided with magnetic valve 27 on the pipelines that they are communicated with, recorder jar liquid phase interface 25 is communicated with the liquid phase interface 3 of surface of shell and is provided with magnetic valve 13 on the pipeline that they are communicated with, feed pump 16, in order to guarantee charging rate, can increase by a feed pressurization pump 17 in feed pump 16 back, recorder jar cold-producing medium output interface 26 is communicated with the filled mouth 6 of surface of shell and is provided with magnetic valve 30 and filled pump 31 on the pipeline that their are communicated with.The weigher 22 of the equipment of filling is provided with weight charging amount controller 32, weight charging amount controller 32 preestablishes upper limit weight and limit weight, when the weight of recorder jar drops to the limit weight value, automatically start charging work, when recorder jar weight reaches upper limit weight, charging work stops automatically, recorder jar can preestablish an insurance weight, the weight charging amount controller 32 of recorder jar detects that weight drops to the value of setting and can not gain in weight automatically the time, export an alarm signal, the cold-producing medium weight of prompting recorder jar is cisco unity malfunction.The heater 23 of the equipment of filling is provided with pressure controller 33 and temperature controller, because when the work of filling, the pressure of recorder jar can reduce along with the output of cold-producing medium, thereby pressure controller 33 can utilize cold-producing medium to increase the characteristic that temperature increases pressure, according to preestablishing numerical value, the work of control heater 23, thereby the pressure of stabilimeter measuring bottle guarantee to fill precision.
Import cold-producing medium to recorder jar:
Recorder jar preestablishes upper limit weight and limit weight, when the weight of recorder jar drops to the limit weight value, automatically start charging work, magnetic valve 13 is opened, feed pump 16 and feed pressurization pump 17 start, liquid refrigerant is from liquid phase interface 3 outputs of stock bottle, through magnetic valve 13, feed pump 16, feed pressurization pump 17 input recorder jars, when recorder jar weight reaches upper limit weight, charging work stops automatically, magnetic valve 27 is opened in charging work, makes the gas phase mouth of recorder jar and pressurized bottle gas phase mouth be communicated with the pressure of equilbristat measuring bottle and pressurized bottle, quickening is imported cold-producing medium to recorder jar, and the heater 23 of recorder jar can not quit work, and to guarantee the pressure stability of recorder jar, fills work at any time.If when raw material pressed the pressure of bottle can not reach the pressure that sets, the charging work meeting of recorder jar temporarily stopped, treating that the pressure of stock bottle reaches when setting value, just recover recorder jar charging work automatically.
