Abstract
The utility model discloses a kind of connection and control structure of pump, and this structure comprises two pumps, and these two pumps lay respectively on two pipelines, and the outlet of these same group of two pipeline tools and entrance, and then described two pumps form parallel-connection structure; Be provided with connecting line between described two pipelines, and the discrepancy two ends of this connecting line are connected with the entry end of a delivery side of pump end and another pump respectively, form the cascaded structure of two pumps.The utility model patent changes great demand for pressure flow in some system, coordinate some valves and pipeline, devise a multi-functional optionally pump to connect and control structure, the operating range of pump can be made greatly to be expanded, we can select suitable ability to work as required, allow pump operation the most interval.
Description
Technical field
The utility model relates to a kind of connection and control structure of pump, divides belong to flow control pump technical field by International Patent Classification (IPC) (IPC).
Background technique
The linkage structure of industrial system or experimental system pump has parallel-connection structure, the feed flow of the fluid that doubles under the condition that maintenance pressure is constant; Or the structure of series connection, superposes lift of pump and carrys out adherence pressure under the condition that maintenance flow is constant.
But in some systems, the flow of convection cell and pressure change span very greatly: sometimes need very little pressure and flow, sometimes need again very high flow, sometimes need again very high pressure, when this acute variation, even if employ the equipment of the control inputs power such as frequency variator, but because each selected pump has a suitable flow pressure scope, only use the pump combination of simple series connection in parallel or simple, the huge flow of required span or pressure can not be obtained.Even if allow pump work in inappropriate working zone by force, the efficiency of pump will be extremely low, also still can not reach required flow or pressure.
Thus, the present inventor's consideration improves the connection of existing pump and control structure, and this programme produces thus.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of connection and control structure of pump, the parallel connection of pump and cascaded structure are designed to one by it, thus the operating range of pump is greatly expanded, we can select suitable ability to work as required, allow pump operation the most interval.
For achieving the above object, the utility model is achieved through the following technical solutions:
The connection of pump and a control structure, this structure comprises two pumps, and these two pumps lay respectively on two pipelines, and the outlet of these same group of two pipeline tools and entrance, and then described two pumps form parallel-connection structure; Be provided with connecting line between described two pipelines, and the discrepancy two ends of this connecting line are connected with the entry end of a delivery side of pump end and another pump respectively, form the cascaded structure of two pumps.
Further, described connecting line is provided with the 3rd valve.
Further, a described delivery side of pump end arranges the second valve, and the entry end of another pump is provided with the first valve, and one of them pump is the first pump, and another pump is the second pump.
Further, the technical parameters such as the first pump and the rated input power both the second pump, rated pressure, rated flow can be identical, also can be different, and the driving mode of pump energy is not limited to electromagnetic force, also can be the gas, liquid etc. with certain potential energy.
Further, described first pump and the second pump can use the power input control device of frequency variator or similar frequency variator, obtain rated power and within power, allow pump in rated range, select suitable flow and pressure.
Further, described first, second and third valve is the regulation control switch with on-off function, except the function of complete break-make, has the function that part is closed or partially opened in addition.
Further, two pipelines and connecting line are fluid circuit, have deformability, can extend arbitrarily, shorten or turn round, and entrance is right and left.
Compared with prior art, advantage of the present utility model:
The utility model patent changes great demand for pressure flow in some system, coordinate some valves and pipeline, devise a multi-functional optionally pump to connect and control structure, the operating range of pump can be made greatly to be expanded, we can select suitable ability to work as required, allow pump operation the most interval.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: refer to shown in Fig. 1, a kind of connection of pump and control structure, this structure comprises two pumps, i.e. the first pump 1A and the second pump 2A, wherein the first pump 1A and the second pump 2A lays respectively on two pipelines, and the outlet of these same group of two pipeline tools and entrance, and then described two pumps form parallel-connection structure.
In aforementioned parallel-connection structure, be horizontally arranged with connecting line between aforementioned two pipelines, and the discrepancy two ends of being somebody's turn to do are connected with the outlet end of the first pump 1A and the entry end of the second pump 2A respectively, form the cascaded structure of two pumps; Wherein the first pump 1A and the second pump A can use the power input control device of frequency variator or similar frequency variator, obtain rated power and within power, allow pump in rated range, select suitable flow and pressure.
Aforementioned connecting line is provided with the 3rd valve 3B, and the outlet end of described first pump 1A arranges the second valve 2B, the second pump 2A entry end be provided with the first valve 1B.
The utility model is in use as follows by the change structure of valve:
Structure one: the first valve 1B door is communicated with, and the second valve 2B is communicated with, and the 3rd valve 3B that breaks opens, and the first pump 1A and the second pump 2A realizes the function of parallel connection, under can ensureing the condition of two pumps pressure separately, realizes the superposition of two pump dutys;
Structure two: the first valve 1B disconnects, and the second valve 2B is communicated with, and the 3rd valve 3B disconnects, and the first pump 1A works alone, and embodies pressure and the flow of the first pump 1A;
Structure three: the first valve 1B is communicated with, and the second valve 2B disconnects, and the 3rd valve 3B disconnects, and the second pump 2A works alone, and embodies pressure and the flow of the second pump 2A;
Structure four: the first valve 1B disconnects, and the second valve 2B disconnects, and the 3rd valve 3B is communicated with, and the first pump 1A and the second pump 2A realize the function of series connection, under can ensureing the condition of two pumps flow separately, realizes the superposition of two pumping pressures.
Above, be only the embodiment utilizing this origination techniques content, the modification that any those skilled in the art use this creation to do, change, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
