Abstract
The utility model discloses a kind of full-automatic flow control device, comprise power supply, AC converter, Wechselstrommotor, metering pump, described AC converter one end is connected with power supply, and the other end is connected with Wechselstrommotor; The rotatingshaft of described Wechselstrommotor is connected with the system of mechanical levers in metering pump, and the liquid outlet of described metering pump is also connected with liquid storage barrel by solenoid valve, and solenoid valve is controlled by Weighing platform.The beneficial effects of the utility model are: by metered flow and weight, make flow control degree of accuracy high, automaticity is high.
Description
Technical field
The utility model relates to Oil Production manufacturing mechanism technical field, is specifically related to a kind of full-automatic flow control device.
Background technique
Existing metering pump mainly comprises Wechselstrommotor, pump head, flow regulation handle, the pump housing, liquid-inlet, liquid outlet.The system of mechanical levers of the rotation of Wechselstrommotor in the pump housing drives pump housing inner carrier or barrier film to realize to-and-fro motion, piston or barrier film will be transferred liquid at reciprocating front half cycle and suck pump head by liquid-inlet, and in second half, fluid expulsion pump head is entered to liquid outlet, thereby realize the conveying of liquid material, from the working principle of metering pump, change the object that reciprocating length of stroke each time can reach liquid feed flow.By turning flow regulation handle, can change reciprocating length of stroke and then change flow.Flow-rate adjustment poor linearity, because mechanical linkage is to become to-and-fro motion by rotatablely moving, so length of stroke and regulating handle to turn between angle be not linear relationship, thereby increased the operation easier of quantitative adjusting; Changing flow can only can not realize the automation of Flow-rate adjustment by production scene manual operation, and is independent Primary regulation, and degree of accuracy is low.
Summary of the invention
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of full-automatic flow control device is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of full-automatic flow control device described in the utility model, comprises power supply, AC converter, Wechselstrommotor, metering pump, and described AC converter one end is connected with power supply, and the other end is connected with Wechselstrommotor; The rotatingshaft of described Wechselstrommotor is connected with the system of mechanical levers in metering pump, and the liquid outlet of described metering pump is also connected with liquid storage barrel by solenoid valve, and solenoid valve is controlled by Weighing platform.
As the preferred embodiment of this programme, the system of mechanical levers in described metering pump is connected with piston or barrier film; Thereby described AC converter changes the reciprocating frequency of the rotating speed change pump of Wechselstrommotor by frequency conversion.
As the preferred embodiment of this programme, the proportional relation of rotating speed of described reciprocating frequency and Wechselstrommotor.
As the preferred embodiment of this programme, described Weighing platform is provided with input keyboard and display unit.
Adopt after said structure, the utility model beneficial effect is: by metered flow and weight, make flow control degree of accuracy high, automaticity is high.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is overall structure figure of the present utility model.
In figure: 1, AC converter, 2, Wechselstrommotor, 3, metering pump, 4, solenoid valve, 5, liquid storage barrel, 6, Weighing platform.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of full-automatic flow control device, comprises power supply, AC converter 1, Wechselstrommotor 2, metering pump 3, and described AC converter 1 one end is connected with power supply, and the other end is connected with Wechselstrommotor 2; The rotatingshaft of described Wechselstrommotor 2 is connected with the system of mechanical levers in metering pump 3, the liquid outlet of described metering pump 3 is also connected with liquid storage barrel 5 by solenoid valve 4, solenoid valve 4 is controlled by Weighing platform 6, and the system of mechanical levers in described metering pump 3 is connected with piston or barrier film; Thereby described AC converter 1 changes the reciprocating frequency of the rotating speed change pump of Wechselstrommotor 2 by frequency conversion, thereby change fluid flow, reduced the operation easier of quantitative adjusting, realized the automation of Flow-rate adjustment, liquid by 6 pairs of splendid attires of Weighing platform is weighed, unlatching of controlling again solenoid valve etc. has further improved the validity of flow control, and Weighing platform 6 is provided with input keyboard and display unit, shows current weight.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solutions of the utility model, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
