DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0032] In the related art, a water outlet joint is designed on the pump body of a magnetic levitation self-priming pump. The water outlet joint serves as the outlet of the pump and is used to discharge the gas and liquid in the pump body. Usually, the water outlet joint is designed as an integral part of the pump body. However, since the flow channels for exhaust and discharge need to be processed in the water outlet joint, the integral design of the water outlet joint and the pump body saves the installation steps between the two. However, the processing of the flow channels inside the water outlet joint is extremely inconvenient.

[0033] Based on this, an exemplary embodiment of the present application provides a magnetically levitation self-priming pump with a split water outlet joint, the magnetically levitation self-priming pump includes a pump body, the pump body includes a gas-liquid separation part, the water outlet joint is arranged on the gas-liquid separation part, and a detachable design is adopted between the water outlet joint and the gas-liquid separation part. In this way, the exhaust and discharge flow channels inside the water outlet joint can be processed first, and after the processing is completed, the water outlet joint can be installed on the pump body to simplify the processing steps and difficulty of the flow channel, improve the processing convenience and efficiency, and reduce the processing cost.

[0034] An exemplary embodiment of the present application provides a magnetic suspension self-priming pump with a split water outlet section 300, such as Figure 1 As shown, the magnetic levitation self-priming pump includes a pump body 100, a rotor (not shown in the figure), a pump cover 200, a motor 400 and a water outlet section 300; the pump cover 200 is arranged on one side of the pump body 100, and a receiving chamber 102 for accommodating the rotor is formed between the pump cover 200 and the pump body 100, and an inlet 201 for liquid inflow is arranged on the pump cover 200; the motor 400 is arranged on the other side of the pump body 100, for driving the rotor to rotate; the rotor is suspended and non-contactly arranged in the receiving chamber 102, and under the drive of the motor 400, the rotor rotates in the receiving chamber 102, and an impeller is arranged on the rotor; the pump body 100 includes a gas-liquid separation part 101; the water outlet section 300 is arranged on the gas-liquid separation part 101, and an outlet 309 for liquid or gas outflow is arranged on the water outlet section 300; under the drive of the motor 400, the rotation of the rotor drives the impeller to rotate, and the liquid is pumped from the inlet 201 to the outlet 309.

[0035] There can be many ways to connect the water outlet node 300 and the gas-liquid separation part 101. In an exemplary embodiment, the water outlet node 300 and the gas-liquid separation part 101 are connected by welding. At this time, after the water outlet node 300 is processed, the water outlet node 300 is welded to the pump body 100. This not only facilitates the processing of the water outlet node 300 before welding, but also, through welding, a high-strength connection between the water outlet node 300 and the pump body 100 can be achieved.

[0036] In one embodiment, the water outlet node 300 and the gas-liquid separation part 101 are connected by bonding. By bonding, the water outlet node 300 and the pump body 100 can be quickly connected to achieve a quick connection between the two.

[0037] In one embodiment, a through hole is provided on the water outlet node 300, and a threaded hole is pre-provided on the gas-liquid separation part 101. After the water outlet node 300 and the pump body 100 are processed, the water outlet node 300 and the gas-liquid separation part 101 are connected by fasteners.

[0038] like Figures 2 to 5 As shown, the water outlet section 300 includes a first section 301, a second section 302 and a third section 303 connected in sequence, the first section 301 is a cuboid or a cube, the second section 302 and the third section 303 are cylinders, and the cross-sections of the first section 301, the second section 302 and the third section 303 decrease in sequence.

[0039] like Figures 6 to 8 As shown, a first gas-liquid separation chamber 103 is provided in the gas-liquid separation part 101. In order to obtain a larger volume of the first gas-liquid separation chamber 103, and limited by the size of the pump body 100, preferably, the cross-sectional shape of the gas-liquid separation part 101 is rectangular. The cross-sectional shape of the first gas-liquid separation chamber 103 is rectangular, for example, it can be rectangular, square, of course, it can also be circular, elliptical, etc., but, limited by the size of the pump body 100, and in order to obtain a larger gas-liquid separation chamber, the cross-sectional shape of the first gas-liquid separation chamber 103 is preferably rectangular. At this time, the volume of the gas-liquid separation chamber is the largest, which can accelerate the separation between gas and liquid, and the gas-liquid separation effect is good. In order to improve the effect of gas-liquid separation, a baffle 104 is provided in the gas-liquid separation chamber. At the initial stage of the start-up of the magnetic levitation self-priming pump, the gas and liquid in the pump body 100 will flow together to the outlet 309. At this time, the baffle 104 can effectively block the upward movement of the liquid, and let the liquid fall back, so that the gas first flows to the outlet 309, so as to accelerate the separation between the gas and liquid and increase the effect of gas-liquid separation.

[0040] In order to facilitate the connection between the water outlet joint 300 and the pump body 100, the cross-sectional shape of the first section 301 of the water outlet joint 300 is adapted to the cross-sectional shape of the gas-liquid separation part 101, and a second gas-liquid separation chamber 304 is provided in the water outlet joint 300. The cross-sectional shape of the second gas-liquid separation chamber 304 is adapted to the cross-sectional shape of the first gas-liquid separation chamber 103. The second gas-liquid separation chamber 304 and the first gas-liquid separation chamber 103 together form a gas-liquid separation chamber. The gas and liquid are separated in the gas-liquid separation chamber, and the gas is discharged first and the liquid is discharged later, so that a stable liquid absorption capacity can be maintained.

[0041] The water outlet section 300 is also provided with a first water outlet chamber 305, a second water outlet chamber 306 and a third water outlet chamber 307 which are interconnected. The first water outlet chamber 305 is interconnected with the second gas-liquid separation chamber 304 to form a flow channel for liquid and gas to flow out. In one embodiment, the diameter of the first water outlet chamber 305 is smaller than the diameter of the third water outlet chamber 307. In this case, the first water outlet chamber 305 can achieve the function of controlling the flow rate. According to the flow rate requirements, the water outlet section 300 can be modularly designed. For example, the size of the first section 301 of the water outlet joint 300 can be kept unchanged, that is, the size of the installation interface between the water outlet joint 300 and the pump body 100 can be kept unchanged, and only the size of the second section 302 and the third section 303 can be changed, and the first water outlet chamber 305, the second water outlet chamber 306 and the third water outlet chamber 307 of different specifications and sizes can be designed. By controlling the size of the first water outlet chamber 305, the second water outlet chamber 306 and the third water outlet chamber 307, the purpose of controlling the flow rate can be achieved. According to the requirements of different flow rates, only the water outlet joints 300 of different specifications need to be replaced to meet the requirements of different flow rates. The water outlet joint 300 adopts a modular design. By replacing the water outlet joints 300 of different specifications, the flow rate of the pump can be controlled, and the function of changing the flow rate of the pump by only replacing the water outlet joint 300 can be achieved, thereby improving the diversity of the pump.
