Brief description of the drawings
Fig. 1 is the one-piece construction schematic diagram of a kind of stable low discharge automated fluid drug delivery pump system of the utility model.
Embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the utility model is further elaborated.
As shown in Figure 1, a kind of stablize low discharge automated fluid drug delivery pump system, this system comprises: liquid flowing tube 1, flow regulator 2, electric diaphragm pump 3, pressure-detecting device 4, get liquid hand valve 5, liquid pushing tube 6 and power supply adaptor 7.
As shown in Figure 1, the liquid end of getting of electric diaphragm pump 3 is connected with liquid flowing tube 1, and the outlet end of this electric diaphragm pump 3 is connected with the input end of flow regulator 2.The input end of pressure-detecting device 4 is connected with the output terminal of flow regulator 2.The input end of getting liquid hand valve 5 is connected with the output terminal of pressure-detecting device 4.Liquid pushing tube 6 is connected with the output terminal of getting liquid hand valve 5.Power supply adaptor 7 is connected with the control end of pressure-detecting device 4, the power input of electric diaphragm pump 3 respectively.Power supply adaptor 7 is connected with external power source.
Flow regulator 2 is throttling valve, adopts needle-valve to be used as flow regulator 2 in the present embodiment.In the time that low discharge fluid is carried, have resistance, can produce pressure drop, flow is diminished, the liquid pushing tube 6 of guaranteeing to be arranged on after flow regulator 2 can be sent the liquid of stability of flow at smaller value.
In the application, adopt small-sized electric membrane pump as electric diaphragm pump 3.At the interior fluid pressure of liquid flowing tube 1, in less in the situation that, this electric diaphragm pump 3 has the characteristic of stable output flow.
In the application, adopt pressure switch as pressure-detecting device 4.Pressure-detecting device 4 can capping operating pressure value, lower limit return difference force value.
In practical work process, connect external power source by power supply adaptor 7, according to actual needs, open and regulate and get after liquid hand valve 5, the pressure size of the delivery outlet of liquid pushing tube 6 is atmospheric pressure, in liquid pushing tube 6, there is liquid stabilising outwards to flow out, the fluid pressure that makes to stablize in low discharge automated fluid drug delivery pump system reduces, in the time that pressure is less than the lower limit return difference force value that pressure-detecting device 4 sets, pressure-detecting device 4 is controlled power supply adaptor 7 and starts electric diaphragm pump 3 and successively transport liquid and export to the delivery outlet of liquid pushing tube 6.
Close and get liquid hand valve 5, the liquid of stablizing in low discharge automated fluid drug delivery pump system flows nowhere, electric diaphragm pump 3 continuous firings, the fluid pressure that makes to stablize in low discharge automated fluid drug delivery pump system increases, in the time that pressure is greater than the upper limit operating pressure value that pressure-detecting device 4 sets, pressure-detecting device 4 is controlled power supply adaptor 7 by electric diaphragm pump 3 power-off, makes electric diaphragm pump 3 out of service.This stable low discharge automated fluid drug delivery pump system has realized stable low discharge, automated fluid conveying function.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.Read after foregoing those skilled in the art, for multiple amendment of the present utility model and substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
