Description

Technical Field

[0001] The utility model relates to the technical field of water pump flow control, and particularly relates to a water pump flow optimization control component. Background Technique

[0002] The optimization control of water pump flow can be achieved through various methods, mainly including adjusting the speed of the water pump, using bypass regulation, regulating through the outlet valve, and adopting variable angle regulation and impeller replacement, etc. Among them, adjusting the speed of the water pump is a common and frequently used method. However, the method of controlling the flow by simply adjusting the speed of the water pump for a long time is likely to shorten the service life of the water pump and exacerbate the damage of pump body parts. Content of the Utility Model

[0003] In order to overcome the defects existing in the prior art, the present utility model provides a water pump flow optimization control component to solve the problems that the method of controlling the flow by simply adjusting the speed of the water pump for a long time is likely to shorten the service life of the water pump and exacerbate the damage of pump body parts.

[0004] To achieve the above object, a water pump flow optimization control component is provided, including: a water pump body and a flow control valve. The left side of the water pump body is installed and connected with a flow control valve through a water outlet pipe.

[0005] The surface of the water outlet pipe is embedded with a first water pressure sensor and a second water pressure sensor. A flow control valve is arranged at the distance between the first water pressure sensor and the second water pressure sensor. A flow electric control box is arranged above the flow control valve. A water pump regulator and a differential pressure type flow controller are arranged inside the flow electric control box. The differential pressure type flow controller is electrically connected with the first water pressure sensor and the second water pressure sensor.

[0006] Further, the left end flange of the water pump body is connected with a water outlet pipe, the right end flange of the water pump body is connected with a water inlet pipe, and the water pump regulator is electrically connected with the water pump body.

[0007] Further, a flow meter is installed on the surface of the water outlet pipe; and the flow meter is located at the left end of the first water pressure sensor. A fixed table is arranged on the lower end surface of the flow electric control box.

[0008] Further, a remote transmission device is placed on the surface of the partition inside the flow electric control box. A rectangular wire groove is formed on the surface of the fixed table.

[0009] Further, ventilation covers are welded on the left and right sides of the flow electric control box; and the ventilation covers are communicated with the inner cavity of the flow electric control box. A dehumidification mesh plate is inserted into the ventilation cover.

[0010] Further, a water receiving box is inserted into the lower end surface of the ventilation cover; and the water receiving box is located below the dehumidification mesh plate. Hygroscopic particles are filled inside the dehumidification mesh plate.

[0011] Further, the differential pressure flow controller, the first water pressure sensor, and the second water pressure sensor constitute a water pressure difference monitoring structure of the flow control valve.

[0012] The beneficial effect of the present utility model is that the water pump flow optimization control component of the present utility model uses a differential pressure flow controller and two groups of water pressure sensors to monitor the water pressure difference of the flow at both ends of the flow control valve. When the monitored water pressure difference is too large, the water pump regulator automatically adjusts the water pump speed to reduce the water pressure difference of the flow at both ends of the flow control valve, weaken the impact of the water pressure at the larger flow end on the flow control valve, facilitate the coordinated control of the water pump regulator and the flow control valve to control the flow rate, avoid frequent adjustment of a single flow control component, and improve the service life of the water pump flow optimization control component.

Detailed Embodiment

[0018] Referring to Figures 1 to 4 as shown, the present utility model provides a water pump flow optimization control component, including: a water pump body 1 and a flow control valve 2. The flow control valve 2 is installed and connected to the left side of the water pump body 1 through a water outlet pipe 11.

[0019] A first water pressure sensor 53 and a second water pressure sensor 54 are embedded and installed on the surface of the water outlet pipe 11. A flow control valve 2 is arranged at the interval between the first water pressure sensor 53 and the second water pressure sensor 54. A flow electric control box 3 is arranged above the flow control valve 2. A water pump regulator 5 and a differential pressure type flow controller 52 are arranged inside the flow electric control box 3. The differential pressure type flow controller 52 is electrically connected to the first water pressure sensor 53 and the second water pressure sensor 54.

[0020] The water pump flow optimization control component uses the differential pressure type flow controller 52 and two groups of water pressure sensors to monitor the water pressure difference of the flow at both ends of the flow control valve 2. When the monitored water pressure difference is too large, the water pump regulator 5 automatically adjusts the rotation speed of the water pump, so that the water pressure difference of the flow at both ends of the flow control valve 2 is reduced, and the impact of the water pressure at the larger flow end on the flow control valve 2 is weakened, which is convenient for the water pump regulator 5 and the flow control valve 2 to cooperate with each other to control the flow size, avoid frequent adjustment of a single flow control component, and improve the service life of the water pump flow optimization control component.

[0021] In this embodiment, the left end flange of the water pump body 1 is connected to the water outlet pipe 11, and the right end flange of the water pump body 1 is connected to the water inlet pipe 13. The water pump regulator 5 is electrically connected to the water pump body 1. A flow meter 12 is installed on the surface of the water outlet pipe 11; and the flow meter 12 is located at the left end of the first water pressure sensor 53. A fixed platform 4 is arranged on the lower end surface of the flow electric control box 3. A remote transmission device 51 is placed on the surface of the partition inside the flow electric control box 3. A rectangular wire trough is opened on the surface of the fixed platform 4.

[0022] As a preferred implementation manner, the water pump regulator 5 controls the rotation speed of the water pump body 1 according to the received water pressure difference, adjusts the size of the water pump flow, is convenient to cooperate with the flow control valve 2 to control the flow size, and avoids the damage of the control component caused by single adjustment control. The specific circuit connection is an existing and mature technology, so it will not be elaborated too much here. For the water pump body and the flow control valve, the left side of the water pump body is connected and installed with a flow control valve through a water outlet pipe.

[0023] A first water pressure sensor and a second water pressure sensor are embedded and installed on the surface of the water outlet pipe. A flow control valve is arranged at the interval between the first water pressure sensor and the second water pressure sensor. A flow electric control box is arranged above the flow control valve. A water pump regulator and a differential pressure type flow controller are arranged inside the flow electric control box. The differential pressure type flow controller is electrically connected to the first water pressure sensor and the second water pressure sensor, which is convenient for remotely viewing the operation condition of the water pump flow optimization control component.

[0024] In this embodiment, ventilation hoods 31 are welded on the left and right sides of the flow control box 3; the ventilation hood 31 is connected to the inner cavity of the flow control box 3, and a dehumidification mesh plate 32 is inserted into the inner side of the ventilation hood 31. A water box 33 is inserted into the lower end surface of the ventilation hood 31; the water box 33 is located below the dehumidification mesh plate 32, and the inner side of the dehumidification mesh plate 32 is filled with moisture-absorbing particles.

[0025] As a preferred implementation, the dehumidification mesh plate 32 inserted into the side end cover of the flow control box 3 absorbs moisture in the air entering the box, preventing electrical equipment in the flow control box 3 from malfunctioning due to moisture, and ensuring the normal operation of the water pump flow control component.

[0026] In this embodiment, the differential pressure flow controller 52 , the first water pressure sensor 53 and the second water pressure sensor 54 constitute a water pressure difference monitoring structure of the flow control valve 2 .

[0027] As a preferred embodiment, the water pressure difference monitoring structure of the flow control valve 2 is convenient for real-time detection of the water pressure difference on both sides of the valve body after adjusting the flow, so as to avoid excessive water pressure at one end impacting the valve body and causing damage to the valve body. When the difference is too large, the water pressure is reduced by adjusting the speed of the water pump to reduce the difference, thereby achieving the effect of reducing the intensity of the water pressure impact.

[0028] The water pump flow optimization control component of the utility model can effectively solve the problem that the long-term flow control method of adjusting the water pump speed alone can easily shorten the service life of the water pump and aggravate the damage of the pump body parts, reduce the impact of the water pressure at the larger flow end on the flow control valve, facilitate the water pump regulator and the flow control valve to coordinate with each other to control the flow size, avoid frequent adjustment of a single flow control component, and increase the service life of the water pump flow optimization control component. The utility model is suitable for water pump flow optimization control components.
