Technical Field
[0001] This invention relates to the field of mechanical equipment technology, and in particular to a horizontal pipeline pump body with dual control interfaces. Background Technology
[0002] Household water pumps are small pumps widely used for increasing tap water levels, replenishing water for solar water heaters, extracting pond and well water, and boosting pressure. Their small size and flexible installation make them suitable for both indoor and outdoor applications under certain conditions. Traditional household water pumps lack automatic control functions. Automatic features include water shortage alarms and automatic start / stop. To add automatic control, users need to purchase a separate controller. While this controller provides the necessary functions, it increases installation space requirements and can also cause head loss and increased noise, causing inconvenience to the end user.
[0003] To address the issue of automatic control, many integrated flow and pressure control devices for water pumps have emerged. However, the layout of the flow and pressure switches varies significantly depending on the pump body structure, which affects the structural dimensions and pump efficiency. Therefore, we propose a horizontal pipeline pump body with a dual-control interface. Summary of the Invention

Detailed Implementation
[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Example 1 Please see Figures 1-4 A horizontal pipeline pump body with dual control interfaces includes a pump body 1. An outlet 101 is located at the center of the top of the pump body 1. A flow switch interface 102 and a water injection bolt interface 103 are respectively located on both sides of the outlet 101. A pressure switch interface 107 is horizontally located on one side of the outlet 101. Pump body mounting threaded holes 105 are fixedly provided on the outer side of the pump body 1. A spiral vortex chamber 108 is provided inside the pump body 1. The spiral vortex chamber 108 is rotatably arranged, and a diffuser 106 is provided at the top of the spiral vortex chamber 108. The diffuser 106 is connected to the flow switch interface 102 via a pipeline. The pump body 1 is provided with a drain bolt interface 104, and a drain bolt 6 is provided on the drain bolt interface 104. The upper part of the pump body 1 is provided with a water injection bolt interface 103, and a water injection bolt 7 is provided through the water injection bolt interface 103. Both the water injection bolt 7 and the drain bolt 6 extend into the interior of the spiral vortex chamber 108.
[0020] The flow switch interface 102 is vertically positioned, and a flow switch 2 is mounted on the flow switch interface 102 via a G-thread. The flow switch 2 includes a flow float, a magnet, and a spring, and the stroke range of the flow switch 2 inside the outlet pipe is achieved by an interference-fitted copper ring.
[0021] The pump body 1's pressure chamber employs a spiral vortex chamber 108, relying on the change in the cross-sectional area of the volute at the flow channel outlet to convert the fluid's kinetic energy into pressure energy. At the pump flow channel outlet, a vertical outlet 101 is designed to ensure the normal opening and closing function of the flow switch 2 while fully utilizing the layout space and reducing installation dimensions. A horizontal pressure switch interface 107 is designed at the flow channel outlet near the motor 5, ensuring that the pressure switch 3 does not occupy excessive installation space. To ensure the reliable operation of the flow switch 2 and to protect the installation environment, an interference-fit copper ring is used within the stroke range of the flow switch 2 at the pump body 1's outlet flow channel.
[0022] The outlet 101 is located on one side of the flow float's active area in the flow switch 2, and the outlet pipe adopts a 90° equal-diameter elbow. The pressure switch interface 107 is located at the flow channel outlet of the pump body 1, and the pressure switch interface 107 is fitted with a pressure switch 3 via a G-thread. The pressure switch 3 has a single-contact clutch inside.
[0023] Flow switch 2 is activated by water-driven float, which compresses the spring to bring the magnet into contact with a magnetic proximity switch. This, in turn, transmits a signal to control junction box 4 via a sensor, activating the water pump. Flow switch 2 is installed and sealed at the pump body 1 via a G-thread.
[0024] The pump body is mounted with threaded holes 105, through which the motor 5 is connected by bolts. A control junction box 4 is located on one side of the upper part of the motor 5. The control junction box 4 is rotated vertically to the left by 45° and fixed to the motor 5 housing by bolts. Sensors are installed at the ends of both the flow switch 2 and the pressure switch 3, and the wires of the flow switch 2 and the pressure switch 3 are connected to the control circuit of the control junction box 4. The surface of the control junction box 4 is equipped with push-button switches and indicator lights, and the interior of the control junction box 4 contains a PCB and an HMI circuit board, which are connected to the leads of the flow switch 2 and the pressure switch 3.
[0025] The water pump controls the flow switch 2 and pressure switch 3 via the switch on the control box 4. Water enters through the inlet and enters the spiral vortex chamber 108. The motor 5 drives the water flow into the diffuser 106 and out through the outlet 101.
