Detailed Description
The utility model is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present utility model are shown in the drawings.
In the flow test process of the existing water pump, the test pipeline often selects a smaller pipeline caliber (such as DN 50) to meet the test requirement under the conditions of low power, low flow and small caliber, but the pipeline caliber cannot be suitable for meeting the test requirements under other states, so that a water pump operation test system applicable to the test requirements of various states is required.
Example 1
In order to overcome the above disadvantages, the present utility model provides a water pump operation test system, as shown in fig. 1, applied to a water pump to be tested, including:
at least two input pipelines 1 with different flow rates, wherein the water outlet end of the input pipeline 1 is connected with the water inlet of the water pump 3 to be tested through a first transfer unit 2;
at least two output pipelines 4 with different flow rates, wherein the water inlet end of the output pipeline 4 is connected with the water outlet of the water pump 3 to be tested through a second switching unit 5; the differential flow rate depends on one or more of the length, the bending degree and the pipe diameter of the input pipeline and the output pipeline;
and the total flow through the inlet line 1 is equal to the total flow through the outlet line 4. Thus, with respect to the input lines 1, the differences in length, curvature and pipe diameter will result in a differential flow rate between the input lines 1, which differential, under the adjustment of the valve, will allow the input of a total flow rate at various values. The same applies to the output pipeline 4 to control the total output flow.
Specifically, when the length of the input pipeline 1 and/or the output pipeline 4 is longer, the corresponding liquid flow rate is lower and the flow rate is smaller for the water pump to be tested under the same power; when the bending degree of the input pipeline 1 and/or the output pipeline 4 is larger, namely the bending condition in the pipeline is more, the energy lost by the liquid flow is more, the speed is further lower, and the flow is smaller; the smaller the pipe diameter of the inlet line 1 and/or the outlet line 4, the smaller the flow rate at a certain flow rate.
The input pipeline 1 and the output pipeline 4 are connected with the water storage unit 7, and the input pipeline 1 and the output pipeline 4 are respectively provided with a valve 6. Wherein the input pipeline 1 is connected below the side of the water storage unit 7, and the output pipeline 4 is connected above the side of the water storage unit 7. The number of interfaces of the first switching units 2 corresponds to the number of input pipelines 1, and the number of the second switching units 5 corresponds to the number of output pipelines 4. The valve 6 may be a solenoid valve, and is electrically connected to an external control unit. External control units include, but are not limited to, the use of programmable logic controllers (Programmable Logic Controller, PLCs).
In the process of testing the water pump, the total flow of the water pump needs to reach a water pump demand point, and the demand point can be the maximum flow, the minimum flow or the intermediate flow between the maximum flow and the minimum flow. It is therefore necessary to adjust the valve 6 to which the inlet line 1/outlet line 4 is connected correspondingly. It should be noted that the flow rates of the input pipelines 1 may be the same or different, so long as the total flow rate is ensured to reach the water pump demand point, and then the rated flow rate value of the water pump to be measured is obtained.
In addition, the water pump operation test system also comprises a heating unit 14, wherein the heating unit 14 is arranged at the side part of the water storage unit 7 and extends into the water storage unit 7;
the heating unit 14 is electrically connected to an external control unit. The heating unit 14 is used to heat the liquid (not limited to water) in the water storage unit 7 to simulate the actual water pump working environment.
According to the water pump operation test system provided by the embodiment of the utility model, the plurality of input pipelines and the plurality of output pipelines are arranged, so that the total flow flowing through the water pump can meet the requirement points of the water pump under different tests by utilizing the flow of the input pipelines and the flow of the output pipelines respectively regulated by the valves in the water pump operation test process, and the water pump operation test system can further adapt to the test requirements of various states.
Example two
In an alternative embodiment, the number of the input pipelines 1 and the number of the output pipelines 4 are the same.
For example, if the input pipeline 1 includes the first input pipeline 8 and the second input pipeline 9, and correspondingly, the output pipeline 4 includes the first output pipeline 10 and the second output pipeline 11, the first switching unit 2 and the second switching unit 5 are all three-way tools. The first switching unit 2 is sequentially connected with a first input pipeline 8, a second input pipeline 9 and a water inlet of the water pump 3 to be tested; similarly, the second switching unit 5 is sequentially connected with the first output pipeline 10, the second output pipeline 11 and the water outlet of the water pump 3 to be tested.
And as shown in fig. 2, the first inlet line 8 has a length smaller than the second inlet line 9 and the first outlet line 10 has a length greater than the second outlet line 11. The length differences between the first inlet line 8 and the second inlet line 9, the first outlet line 10 and the second outlet line 11 are mainly taken into account in the actual installation environment and the test requirements.
In an alternative embodiment, the length difference may be an arc-shaped pipeline instead of the original linear pipeline. For example, when an obstacle exists on part of the input pipelines and/or part of the output pipelines, the obstacle avoidance is realized by adopting an arc-shaped pipeline or increasing the bending number of the input pipelines and/or the output pipelines.
When the lengths are different, the flow is different, so that the requirements of the test under different states on the total flow of the water pump are met.
Similarly, in another embodiment, the number of bends in the first supply line 8 is smaller than that in the second supply line 9; the number of bends in the first outlet line 10 is smaller than that in the second outlet line 11. The difference of the bending quantity can also cause the difference of the flow, so that the requirement on the total flow of the water pump under different state tests is met.
In order to ensure statistics on the total flow of the water pump, the first output line 10 and the second output line 11 are each provided with a flow meter 12. Based on the feedback from the flow meter 12, the external control unit is used to adjust the opening/closing of the solenoid valve to adjust the total flow through the pump.
It should be added here that the corresponding connection of the first input line 8, the second input line 9, the first output line 10 and the second output line 11 with the tee joint tool is provided with a quick connection clamp 13. The quick connection clamp 13 is used for preventing the input/output pipeline 4 and the tee joint tooling from falling off, thereby causing potential safety hazard.
Example III
Based on the foregoing embodiments, it is further proposed that the number of the input pipelines and the number of the output pipelines may be different, so that the total flow of the water pump to be tested needs to be subjected to superposition operation by the flow meter of the output pipeline.
As shown in fig. 3, assuming that the number of input pipelines is 3 and the number of output pipelines is 4, each output pipeline is provided with a flowmeter 12. In the process of testing, valves 6 arranged on the input pipeline and the output pipeline are respectively opened, so that the sum of readings of the flow meters 12 reaches the requirement point of the water pump. The reason for adopting 3 input pipelines and 4 output pipelines can be limited by the use environment of the water pump to be tested and the water storage unit. For example, in the actual use process, only small-diameter pipelines can be accommodated between the two pipelines, so that the test requirement is met by increasing the number of the pipelines (input pipelines and output pipelines). In the use process, an input pipeline is connected with the water pump 3 to be tested through the first switching unit 2, and an output pipeline is connected with the water pump 3 to be tested through the second switching unit 5, so that the water circulation in the water storage unit 7 is realized.
In the present utility model, some azimuth terms, such as "upper", "lower", "left", "right", "inner" and "outer", are defined, and unless otherwise stated, these terms are used for convenience of understanding, and thus do not limit the scope of the present utility model.
In the present utility model, unless expressly stated or limited otherwise, a first feature "above" or "below" a second feature may include both the first and second features being in direct contact, as well as the first and second features not being in direct contact but being in contact with each other through additional features therebetween. Moreover, a first feature being "above," "over" and "on" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature. The first feature being "under", "below" and "beneath" the second feature includes the first feature being directly under and obliquely below the second feature, or simply means that the first feature is less level than the second feature.
In the description of the present utility model, unless explicitly stated and limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
