Description

Technical Field

[0001] This utility model relates to the field of corrosion-resistant pump technology, and in particular to a corrosion-resistant pump that is easy to load and unload. Background Technology

[0002] A corrosion-resistant centrifugal pump is a pump that uses the centrifugal force generated by the rotation of an impeller to transport liquids. Centrifugal pumps work by using the centrifugal motion of water caused by the rotation of the impeller. Before starting the pump, the pump casing and suction pipe must be filled with water. Then, the motor is started, causing the pump shaft to drive the impeller and water to rotate at high speed. The water undergoes centrifugal motion, being thrown towards the outer edge of the impeller and flowing into the pump's discharge pipe through the flow channel of the volute casing. The basic structure of a centrifugal pump consists of six parts: impeller, pump body, pump shaft, bearings, sealing ring, and stuffing box. The impeller is the core part of the centrifugal pump; it rotates at high speed and has a large output. The blades on the impeller play a major role. The impeller must undergo a static balance test before assembly. The inner and outer surfaces of the impeller must be smooth to reduce frictional losses in the water flow. However, most existing centrifugal pumps are connected to the pipeline using flanges, which makes installation relatively troublesome.

[0003] In most existing centrifugal pumps, the inlet and outlet are connected to the pipeline via flanges. This makes inspection, repair and maintenance of the centrifugal pumps cumbersome, as the flanges need to be disassembled each time, affecting work efficiency. Therefore, there is room for improvement. Utility Model Content

[0004] This invention provides a corrosion-resistant pump that is easy to load and unload, in order to solve the problems mentioned in the background art.

[0005] To address the aforementioned problems, this utility model provides a corrosion-resistant pump that is easy to install and remove, comprising a pump body and a connector. The pump body has an inlet and an outlet connected to a connector. One end of the connector is provided with a flange connecting to the pump body's inlet and outlet. The other end of the connector is provided with a limiting ring, and a threaded sleeve matching the limiting ring is rotatably fitted within the connector. The end of the threaded sleeve away from the limiting ring has internal threads. A water pipe matching the connector is threadedly connected to the threaded sleeve. A first sealing ring is fitted within the connector, located between the limiting ring and the threaded sleeve on the rear side. An annular groove is formed on the outer surface of the limiting ring of the connector, and a second sealing ring is installed within the annular groove.

[0006] Preferably, the second sealing ring covers the surface of the limiting ring.

[0007] Preferably, the second sealing ring is T-shaped.

[0008] Preferably, a handle is mounted on the outside of the threaded sleeve.

[0009] The beneficial effects of adopting the above technical solutions are: A connector is installed in the inlet and outlet of the pump body. Since the water pipe is connected to the connector through a threaded sleeve, it is convenient to install and remove the water pipe in the pump body, which improves the efficiency of water pipe installation and removal in the pump body and improves work efficiency.

[0010] When the water pipe is connected to the connector through the threaded sleeve, the first sealing ring improves the sealing performance between the threaded sleeve and the connector, and the second sealing ring improves the sealing performance between the water pipe and the connector, thereby improving the sealing performance after the water pipe and the connector are connected.

[0014] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0015] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] like Figure 1-2In this embodiment, a corrosion-resistant pump that is easy to install and remove includes a pump body 1 and a connector 2. A connector 2 is connected to the inlet 11 and outlet 12 of the pump body 1, respectively. One end of the connector 2 is provided with a flange 21 connected to the inlet 11 and outlet 12 of the pump body, and the other end of the connector 2 is provided with a limiting ring 22. A threaded sleeve 3 matching the limiting ring 22 is rotatably fitted in the connector 21. The end of the threaded sleeve 3 away from the limiting ring 22 is provided with a thread. A water pipe 4 matching the connector 2 is threadedly connected to the threaded sleeve 3. A first sealing ring 23 is fitted in the connector 2, and the first sealing ring 23 is located between the limiting ring 22 and the threaded sleeve 3. An annular groove 24 is opened on the outer side of the limiting ring 22 of the connector 2, and a second sealing ring 25 is installed in the annular groove 24.

[0018] With the above technical solution, during use, the connector 2 is pre-connected to the inlet 11 and outlet 12 of the pump body 1 via the flange 21. When the water pipe 4 needs to be installed, one end of the water pipe 4 is connected to the threaded sleeve 3. Then, by rotating the threaded sleeve 3 to engage the threads, the water pipe 4 is threaded into the threaded sleeve 3, and the end of the water pipe 4 is aligned with the connector 2, thus completing the installation. During disassembly, the threaded sleeve 3 is rotated to engage the threads, causing the water pipe 4 to retract from the threaded sleeve 3, thereby removing the water pipe 4 from the connector 2. Thus, there is no need to remove the bolts when installing or disassembling the water pipe, improving the efficiency of installation and disassembly. The limiting ring 22 is used to limit the threaded sleeve 3 to prevent it from detaching. The first sealing ring 23 improves the sealing between the threaded sleeve 3 and the connector 2 after installation, and the second sealing ring 25 improves the sealing between the water pipe 4 and the connector 2 after installation, thus making the connection between the connector 2 and the water pipe 4 more stable.

[0019] Preferably, the second sealing ring 25 covers the surface of the limiting ring 22.

[0020] Through the above technical solution, the second sealing ring 25 covers the limiting ring 22, improving the sealing performance after the water pipe 4 is connected to the connector 2.

[0021] Preferably, the second sealing ring 25 is T-shaped.

[0022] Through the above technical solution, the T-shaped fit of the second sealing ring 25 with the annular groove 24 in the limiting ring 22 enables the second sealing ring 25 to be stably installed in the connector 2, thereby ensuring stability during loading and unloading.

[0023] Preferably, a handle 31 is mounted on the outside of the threaded sleeve 3.

[0024] Through the above technical solution, the handle 31 is designed to facilitate the rotation of the threaded sleeve 3, thereby improving the convenience of loading and unloading operations.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
