Abstract
The utility model discloses a manpower self-suction pump used for irrigation, water pumping, or conveying, which comprises two cylinders and four one-way valves, wherein a piston is arranged in each cylinder, and the cylinder is divided into an upper and a lower chambers by using the piston as a boundary; an inlet of a valve is divided into two paths by a pipeline, and each path is connected with two one-way valves to an outlet; the upper chamber of one cylinder is respectively connected between the two one-way valves of each path by the pipeline, and, the lower chambers of the two cylinders are connected by the pipeline. By using the differential action of pistons and the switching intercoordination effects of the one-way valves, when liquid is extruded out from one cylinder, the other cylinder sucks in the liquid, and compared with the prior art, the utility model has the advantage that the efficiency and the flow quantity are largely improved; additionally, one transition chamber can be respectively arranged between the two one-way valves of each path, and the transition chamber is connected with the upper chamber of the cylinder by the pipeline; by using the transition chamber, the discharge pressure of the liquid is much uniform and the variation of fluid flows is much smaller.
Description
One, technical field
The utility model relates to a kind of pump, say so more specifically a kind ofly be used for open-air field irrigation, well draws water or liquid such as various oil plant, industrial chemicals are carried, inverted engines are used manpower self-priming pump.
Two, background technique
At present, China rural area is in the production such as draw water of field irrigation and well, mechanical pump has become basically universal in the life activity, but continuous expansion along with China's energy demand, energy resource supply more and more can't be satisfied the demand, the thing followed is drawn exactly, the outage phenomenon is on the increase, electricity price, oil price rises steadily, this contradiction is particularly outstanding in the rural area, so some rural area has occurred using old-fashioned hand lever pump to draw water again, even the phenomenon of doing it by hand and carry it on one's shoulder and carrying water and irrigating, and using the lever pump to draw water, the piston of lever pump can only be finished once suction in a reciprocation cycle, the work of draining, efficient is lower.In addition, the conveying of flammable and combustible liquids such as oil plant, industrial chemicals, inverted engine etc. can not or the inconvenience place of using mechanical pump, it is general that what adopt is the very little manual gear pump of flow.These manpower pump ubiquity flows are little, and inefficient shortcoming uses effort, bothersome, time-consuming.
Three, summary of the invention
1, goal of the invention: the purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of efficient height to be provided, the manpower self-priming pump that flow is big, and it is in use more laborsaving, save time.
2, technological scheme: in order to achieve the above object, a kind of manpower self-priming pump of the utility model, it comprises two cylinder bodies and four one-way valves, is provided with piston in the cylinder body, cylinder body is that the boundary is divided into epicoele and cavity of resorption with the piston; Pump intake is divided into two-way by pipeline, and each connects two one-way valves to outlet, connects the epicoele of a cylinder body between two one-way valves on every road respectively by pipeline, and the cavity of resorption of two cylinder bodies also couples together by pipeline.
Its working principle is: at first, the piston of one of them cylinder body moves downward under external force, liquid in the cylinder body epicoele produces negative pressure, under suction function with the one-way valve opens at its pump intake place that is connected by pipeline, the outlet port closed check valve, liquid is inhaled in the epicoele through inlet and one-way valve; And simultaneously the liquid of cylinder body cavity of resorption is pressed into through connecting tube in the cavity of resorption of another cylinder body piston jack-up, then the liquid in this cylinder body epicoele is compressed, connected under pressure outlet port one-way valve opens, the ingress closed check valve, liquid is forced out outlet; Otherwise, the piston of opposite side cylinder body is moved downward, also can produce same effect, so repeatedly, the piston in two cylinder bodies is working in reciprocating mode continuously, and liquid then constantly sucks from inlet, extrudes from outlet.
In addition, can also between two one-way valves on each road an adapter cavity be set respectively, adapter cavity is connected with the epicoele of cylinder body by pipeline.Adopt adapter cavity can make the liquid head pressure more even, the liquid rheologyization is littler.
3, beneficial effect: the utility model is owing to adopted two cover cylinder bodies, the mutual coordinative role of switching of the differential and one-way valve by piston, when a cylinder body extrudes liquid, another cylinder body sucks liquid, compares with existing hand pumps such as lever pump, gear pumps, and efficient obviously improves, flow also significantly promotes, and it not only can manually-operable, can also adopt multiple mode of operation such as tramp with one's feet, and has improved the flexibility of using.
