Abstract
The invention provides a novel metering pump, and relates to the technical field of liquid supplying devices. The novel metering pump comprises a power device (1), a crank and connecting rod mechanism (2), a piston (3), a pump body (4), a one-way liquid inlet valve (5), a liquid inlet pipe (6), a one-way liquid outlet valve (7) and a liquid outlet pipe (8), wherein the power device (1) is connected with the upper end of the crank and connecting rod mechanism (2), the lower end of the crank and connecting rod mechanism (2) is connected to the middle of the piston (3) which is arranged in the pump body (4), and both sides at the lower end of the pump body (4) are respectively provided with the one-way liquid inlet valve (5) and the one-way liquid outlet valve (7) which are respectively connected with the liquid inlet pipe (6) and the liquid outlet pipe (8). The novel metering pump has the advantages of simple, scientific and reasonable structure, reduction of manufacturing cost, easiness in maintenance, convenience and rapidness in flow regulation, easiness in operation and high supplying metering precision.
Description
Technical field:
The present invention relates to liquid and carry the equipment technology field, be specifically related to a kind of novel metering pump.
Background technique:
Metering pump is a kind ofly can satisfy various strict process requirementss of process, flow can be in the 0-100% scope step-less adjustment, be used for carrying the special displacement pump of liquid (particularly corrosive liquids).Metering pump also claims metering pump or dosing pump, and it belongs to reciprocating volumetric pump, is used for accurate measurement, require the steady state accuracy of metering pump to be no more than usually ± 1%.Along with modernization industry continuous development towards automation mechanized operation, this situation of far distance automatic controlling, the matching performance of metering pump is strong, adapt to medium (liquid) widely advantage particularly loom large.
Existing metering pump drives worm screw and makes main shaft and eccentric crop rotation rotation motion by worm gear reducer through coupling by motor, and is reciprocating in the slidable adjustment seat by eccentric wheel drive bow type connecting rod.When plunger when the dead point is moved backward, form vacuum in the pump chamber gradually, suction valve is opened, and sucks liquid; When plunger when move at the dead point forward, this moment suction valve closure, expulsion valve is opened, liquid is in plunger discharge during to further motion.Back and forth forming of pump pressure is arranged continuously along also working, quantitative discharge liquid.
But the metering pump mechanism complexity of this kind structure, fabricating cost is higher, the Flow-rate adjustment complex steps, metering carries degree of accuracy not high, and maintenance not only wastes time and energy, and has also increased whole cost.
Summary of the invention:
The purpose of this invention is to provide a kind of novel metering pump, it is simple in structure scientific and reasonable, has reduced fabricating cost, maintenance for ease of maintenaince, and Flow-rate adjustment is convenient and swift, easy operating, and metering delivery precision height.
In order to solve the existing problem of background technique, the present invention is by the following technical solutions: it comprises power plant, connecting rod, piston, the pump housing, unidirectional feed liquor valve, liquid inlet pipe, unidirectional liquid valve and drain pipe, power plant are connected with the connecting rod upper end, the connecting rod lower end is connected to the piston middle part, and piston is arranged in the pump housing, both sides, pump housing lower end are respectively arranged with unidirectional feed liquor valve and unidirectional liquid valve, and unidirectional feed liquor valve is connected with drain pipe with liquid inlet pipe respectively with unidirectional liquid valve.
The present invention drives piston by connecting rod and pumps, because its reciprocal amplitude equalization, so the amount of extraction, extruding liquid is identical, and then metering delivery precision height.
The present invention is simple in structure scientific and reasonable, has reduced fabricating cost, maintenance for ease of maintenaince, and Flow-rate adjustment is convenient and swift, easy operating, and metering delivery precision height.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment:
With reference to Fig. 1, this embodiment is by the following technical solutions: it comprises power plant 1, connecting rod 2, piston 3, the pump housing 4, unidirectional feed liquor valve 5, liquid inlet pipe 6, unidirectional liquid valve 7 and drain pipe 8, power plant 1 are connected with connecting rod 2 upper ends, connecting rod 2 lower ends are connected to piston 3 middle parts, and piston 3 is arranged in the pump housing 4, both sides, the pump housing 4 lower end are respectively arranged with unidirectional feed liquor valve 5 and unidirectional liquid valve 7, and unidirectional feed liquor valve 5 is connected with drain pipe 8 with liquid inlet pipe 6 respectively with unidirectional liquid valve 7.
This embodiment drives piston 3 by connecting rod 2 and pumps, because its reciprocal amplitude equalization, so the amount of extraction, extruding liquid is identical, and then metering delivery precision height.
This embodiment is simple in structure scientific and reasonable, has reduced fabricating cost, maintenance for ease of maintenaince, and Flow-rate adjustment is convenient and swift, easy operating, and metering delivery precision height.
