Abstract
The utility model discloses a metering pump capable of continuously and uninterruptedly metering the output, which comprises metering cylinder bodies and a driving device for driving the metering cylinder bodies to work, wherein the number of the metering cylinder bodies is more than one, inlets of all metering cylinder bodies are mutually communicated, and are connected with a liquid inlet pipe after being communicated, and outlets of all metering cylinder bodies are also mutually communicated, and are connected with a liquid discharge pipe after being communicated. The metering pump can realize the continuously and uninterruptedly output metering, in addition, the flow rate can be flexibly regulated.
Description
Technical field:
The utility model relates to a kind of metering pump.
Background technique:
As fluid delicate metering equipment, nowadays metering pump has been widely used in all trades and professions, and traditional metering pump all only is with a metering cylinder body, in the process of carrying out gage work, because finishing once metering, a metering cylinder body needs through the inspiration fluid, and then the step of discharge fluid, causing the metering pump metering to discharge fluid is that the gap is discontinuous, has a strong impact on the efficient of metering.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, a kind of uninterruptedly metering output continuously to be provided, and to press the metering pump of the quantitative output of any setting capacity.
For achieving the above object, the technological scheme that the utility model provides is: a kind of can be continuously the uninterrupted metering pump of metering output, include the drive unit of metering cylinder body and driving metering cylinder body running, described metering cylinder body is provided with more than one, the inlet of each metering cylinder body interpenetrates, connect the back and be connected with liquid inlet pipe, the outlet of each metering cylinder body is also interpenetrated, and connects the back and is connected with liquid-discharging tube.
After above-mentioned technological improvement, will finish discharge opeing work at a metering cylinder body and enter imbibition when work, and then metering cylinder body in addition begins discharge opeing at once, when having arranged liquid soon, finish the metering cylinder body and then discharge opeing again of imbibition work before, under the cooperation of these metering cylinder bodies, the metering cylinder body all can be arranged from start to finish like this toward the interior discharge opeing of liquid-discharging tube, thereby realizing uninterruptedly pressing continuously the constant basis of being regulated measures discharge opeing work and measures output liquid by the required total amount of each circulation output.Greatly improve metering efficient and pump performance and application.
Description of drawings:
Fig. 1 is the three-dimensional structure diagram of the utility model metering pump;
Fig. 2 is the sectional structure chart of the utility model metering pump.
Embodiment:
Now elaborate the utility model in conjunction with the accompanying drawings:
The metering pump of present embodiment includes two metering cylinder bodies 11,12, each metering cylinder body all carries drive motor, the inlet of two metering cylinder bodies is communicated with to get up by first connecting tube 2 of threeway, first connecting tube 2 is connected with liquid inlet pipe 3, the outlet of each metering cylinder body is communicated with to get up by second connecting tube 4 of threeway, and second connecting tube 4 is connected with liquid-discharging tube 5.
Described drive unit is electronic, and amount of motor rotation is linear with plunger or piston motion in the metering cylinder body.The motor of drive unit can be servo or stepper motor etc., and program control is an adjustable constant basis in the forward discharge capacity sum that operating process allows all measure cylinder bodies, reaches continuously uninterrupted constant output; In addition, the forward discharge capacity summation of all metering cylinder bodies can be set and calculate to program control, thereby, by job requirement, allow metering pump at the liquid of each work cycle output by any setting capacity.
This metering pump is steadily exported by the control of drive motor being realized fluid, can set output quantity, but single output, repeatedly output, output continuously, single and when repeatedly exporting output speed and time adjustable, flow is adjustable when exporting continuously.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
