Detailed Description
The following detailed description of the embodiments of the utility model, given by way of example only, is presented in the accompanying drawings to aid those skilled in the art in a more complete, accurate and thorough understanding of the inventive concepts and aspects of the utility model, and to facilitate their practice.
As shown in fig. 1 and 2, in the water pump installation control structure, one end of a water pump 4 is provided with a water inlet pipe 1, the other end of the water pump is provided with a water outlet pipe 2, the water outlet pipe 2 is connected with a water outlet main pipe 3, a flexible connecting pipe 8 is connected between the water outlet pipe 2 and the water outlet main pipe 3, and a one-way valve 7 is arranged in the water outlet pipe 2.
Compared with the traditional pipeline, the improvement changes the passing path of water flow, so that the water flow passes through the rotameter 6, the one-way valve 7 and the flexible connecting pipe 8 in sequence from the water outlet pipe 2 of the water pump 4 and then is connected into the main pipeline. After the water pump 4 is started, the one-way valve 7 is arranged behind the flowmeter, and no pressure exists in the pipeline from the water outlet to the main pipe port of the water pump 4, so that the load during the starting of the water pump 4 and the vibration and resistance of the main water outlet pipe 3 can be reduced.
As shown in fig. 1 and 2, the water pumps 4 are arranged at equal intervals, and the water pumps 4 are connected with frequency converters. The water pumps 4 with equal intervals are arranged, so that the stability of water flow in the water outlet main pipe 3 can be improved, the change of the flow speed of water flow at the water outlet is avoided, and when a certain water pump 4 fails, the water pump can be detached and replaced under the condition that the normal operation of other water pumps 4 is not affected, the normal operation of a pipeline can be ensured, and compared with the situation that the standby water pump 4 is added in a pipeline, the installation and maintenance cost can be saved.
In the control mode, a frequency converter is arranged to increase the control on the starting of the water pumps 4, each water pump 4 is controlled by the frequency converter, as shown in fig. 2, an operator can set the frequency of the starting of the water pumps 4, so that the instantaneous starting of a plurality of water pumps 4 is avoided, and vibration and impact caused to a main pipeline are avoided; the starting delay time of each water pump 4 can be set, when one water pump 4 is started for 20 seconds, the other water pump 4 can be started, so that the pressure in a pipeline can be reduced, and vibration caused by the simultaneous starting of a plurality of water pumps 4 can be reduced.
As shown in fig. 1, a rotameter 6 is arranged in the water outlet pipe 2, and a flexible connecting pipe 8 is positioned above the rotameter 6. The rotameter 6 has the characteristics of simple structure, visual measurement, small pressure loss, convenient maintenance and the like. Since the flowmeter is generally mounted on a pipe section running vertically in use, the fluid medium passes through the rotameter 6 from bottom to top, so that the flowmeter is suitable for use in a water outlet pipe 2 running vertically. Through the detection of the flow rate of the water flow in the pipeline by the rotameter 6, an operator can judge the operation condition of each part of the pipeline according to the obtained data. If the flexible connecting pipe 8 is arranged at the outlet of the water pump 4, the vibration between the water pump 4 and the main pipeline can be reduced, but the flow meter at the upper part of the flexible connecting pipe 8 still receives the impact of the water flow in the pipeline, and the vibration of the main water outlet pipe 3 can be increased; therefore, the flexible connection pipe 8 is arranged above the flowmeter, which is beneficial to protect the rotameter 6.
An elbow pipe 5 is connected between the top end of the water inlet pipe 1 and the water inlet of the water pump 4. The return bend 5 can follow the water inlet of inlet tube 1 drainage to water pump 4, forms certain buffering effect, makes rivers can not follow the water source and directly get into in the water pump 4, avoids water pump 4 to bear too big water pressure, guarantees its reliability of using.
As shown in fig. 1, the water inlet pipe 1 and the water outlet pipe 2 are both vertically arranged, and the water outlet main pipe 3 is horizontally arranged. The structure can reduce the paths of the water inlet pipe 1 and the water outlet pipe 2, reduce the material consumption of the pipe, fully utilize the length of the pipe, reduce the use cost, and the water outlet pipe 2 arranged in the vertical direction can also be convenient for installing the rotameter 6.
The inner diameter of the flexible connecting pipe 8 is larger than that of the water outlet pipe 2; the middle part of the flexible connecting pipe 8 is in a spherical structure. The structure enlarges the volume of the flexible connecting pipe 8, when the water flow is impacted excessively, the water flow can be temporarily stored in the flexible connecting pipe 8, and the vibration of the pipeline caused by the impact of the water flow is reduced.
As shown in fig. 1, the main water outlet pipe 3 is connected with a supporting rod 9, the top end of the supporting rod 9 is connected with the main water outlet pipe 3, and the supporting rods 9 are arranged at equal intervals. The supporting rod 9 can be used for installing the main water outlet pipe 3, so that the installation position of the main water outlet pipe 3 is accurate, and the water outlet of the main water outlet pipe 3 is guided to a required position; the supporting rod 9 supports the main water outlet pipe 3, and the impact effect of the main water outlet pipe on water flow is improved.

Above-mentioned structure, divide into the straight tube 10 of multistage with outlet pipe 2, can install respectively in with different straight tube 10 with check valve 7 and rotameter 6, convenient installation operation, when the straight tube 10 of somewhere or inside check valve 7 and rotameter 6 need be maintained and changed because of damaging, the required change position of operating personnel can direct judgement, maintains the replacement to the local damaged position of pipeline, consequently can avoid replacing whole outlet pipe 2, reduces the expense of maintenance.
The end parts of the water inlet pipe 1, the bent pipe 5, the water outlet pipe 2 and the flexible connecting pipe 8 are respectively provided with a connecting flange. The connecting flange can be used for directly connecting all the pipelines, so that the pipe orifice of each pipeline is ensured to be positioned accurately, and when the pipeline fails, the connected pipelines can be separated in time through the connecting flange, and maintenance is performed.
As shown in fig. 1 and 2, two broken lines in the drawing are water sources, the arrow direction in the drawing is a water flow passing path, when the water pump 4 is started, water flows into the water pump 4 along the water inlet pipe 1 and the bent pipe 5, then enters the water outlet pipe 2 through the pressurization of the water pump 4, and under the action of the one-way valve 7, the water flow cannot flow back after passing through the one-way valve 7, so that the impact of the backflow water flow and the original water flow can be avoided, the water flow continuously flows in along the water outlet pipe 2, even if the water flow pressure is overlarge, the inner space of the flexible connecting pipe 8 can be continuously filled under the action of the flexible connecting pipe 8, and the water flow can not directly reach the water outlet main pipe 3 due to the caliber and the volume of the flexible connecting pipe 8, so that the water flow can gradually accumulate in the flexible connecting pipe 8 and reduce the flow velocity, and the pipe vibration caused by the impact of the water flow can be reduced. When the flow velocity of the water flow is stable, the impact of the water flow is relatively small, the vibration of the pipeline can not occur, and all the components can operate correctly and stably.
After the improvement, the water pump 4 hardly vibrates the pipeline when being started, the pressure in the pipeline does not suddenly and obviously change, and the frequency of faults is greatly reduced. Through comparison and inspection, the condition that water leakage occurs in the first half year of improvement does not occur, and after improvement, the water pipe is free from water leakage and breakage due to vibration and high pressure in the pipe.
According to the water pump installation control structure, the one-way valve 7 and the soft connecting pipe 8 are additionally arranged in the water outlet pipe 2, so that the impact of water flow on a pipeline and parts on the pipeline is reduced, the vibration of the pipeline is reduced, and the service life of the pipeline is prolonged under the anti-backflow of the one-way valve 7 and the buffering action of the soft connecting pipe 8; the vibration of the pipeline due to water flow impact is further reduced by arranging a plurality of water pumps 4 controlled by the frequency converter and adopting a mode of starting and controlling starting frequency in a delayed manner; and the structure and the layout of the pipeline are optimized, so that the pipeline installation and maintenance process are more convenient, and the use cost is lower.
