[0018] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] To address the technical problem that pumps are difficult to adjust axially after installation, thus hindering their performance, this application provides an adjustable support structure and a centrifugal feed pump that enables overall axial adjustment of the pump after installation, facilitating pump installation and operation.

[0020] Firstly, embodiments of this application provide an adjustable support structure; please refer to [link to relevant documentation]. Figure 1 , Figure 1 This is a three-dimensional structural diagram of an adjustable support structure according to an embodiment of this application. The adjustable support structure includes: a movable part, a fixed part, and an adjusting screw 6. The movable part is used to connect to the base 7 of the pump and has a movable groove extending in a direction parallel to the axis of the pump. The fixed part includes a fixed end and a connecting end that passes through and connects to the movable groove. The adjusting screw 6 is threadedly connected to the movable part, and one end of the adjusting screw 6 is rotatably connected to the connecting end of the fixed part, so that the movable part can be moved relative to the fixed part along the extension direction of the movable groove by the rotation of the adjusting screw 6 on the movable part.

[0021] In this device, a movable part is provided to connect to the pump base 7, and the fixed end of the fixed part is used to fix the fixed part. The movable part of the fixed part is connected to the movable groove. Since the movable groove extends along the direction parallel to the pump axis, and the connection end of the movable part and the fixed part is connected by an adjusting screw 6, the relative position of the movable part and the fixed part can be adjusted by rotating the adjusting screw 6 through the threaded connection between the adjusting screw 6 and the movable part. This allows the movable part to move along the pump axis on the fixed part, thereby causing the pump set to move axially a certain distance relative to the fixed part.

[0022] Preferably, in this embodiment, the movable part includes a support traction plate 1 and a sliding plate 2. The support traction plate 1 is arranged perpendicularly to the sliding plate 2 on the top surface of the sliding plate 2. One side of the support traction plate 1 and one side of the sliding plate 2 are on the same vertical plane and are both used to connect to the pump base 7. Specifically, the support traction plate 1 and the sliding plate 2 are welded and fixed together. One side of the support traction plate 1 and one side of the sliding plate 2 are welded and fixed to one side of the pump base 7. The movable groove is opened in the middle of the sliding plate 2 and is movably connected to the connecting end of the fixed part.

[0023] To secure the support structure, in this embodiment, the fixing part includes an anchor bolt 4 and a slider 5. The top end of the anchor bolt 4 is connected to the movable groove, and the bottom end of the anchor bolt 4 forms the fixing end, which is configured as a hook-shaped structure for prefabrication and fixing in the foundation, achieving full contact and stable support between the support structure and the ground. The top end of the anchor bolt 4 and the slider 5 combine to form a connecting end. The slider 5 is fixedly sleeved at the position where the top end of the anchor bolt 4 extends out of the movable groove, and its bottom surface is in close sliding connection with the movable part. In practice, the adjusting screw 6 passes laterally through the support traction plate 1 on its side and is threadedly connected to the support traction plate 1. One end of the adjusting screw 6 is rotatably connected to one side of the slider 5. In practice, the slider 5 is fixed by the anchor bolt 4, and by rotating the adjusting screw 6, the support traction plate 1 and the sliding plate 2 can be moved at the top end of the anchor bolt 4 to support the pump unit to move axially a certain distance relative to the fixing part.

[0024] To improve the stability of the support installation, in one embodiment, a baffle 3 is provided on the slide plate 2. The baffle 3 is welded and fixed to the top surface of the slide plate 2. One side of the support traction plate 1 is welded and fixed to one side of the baffle 3 to ensure stable installation of the support traction plate 1. In practice, the support traction plate 1, slide plate 2, baffle 3, and pump base 7 are welded together as a whole and installed as a single unit with the pump. Furthermore, the baffle 3 has an elongated groove corresponding to the movable groove. The length and width of the elongated groove and the movable groove are equal to support the axial displacement of the movable part on the fixed part.

[0025] Furthermore, the contact surfaces of the slide plate 2 and the baffle 3 are both smooth surfaces, and the contact surfaces are processed to be very smooth, which can reduce the friction during movement.

[0026] Furthermore, the baffle 3 also has two protruding edges, which are respectively arranged on both sides of the slider 5, so that the slider 5 can only move in a direction parallel to the axis of the pump under the limiting effect of the protruding edges, preventing the slider 5 from radially deviating during the movement.

[0027] Preferably, in this embodiment, two support traction plates 1 are provided, which are arranged side by side and located on both sides of the baffle 3. The inner sides of the two support traction plates 1 are fixed to the two sides of the baffle 3 by welding, so that the movable part forms a more stable connection structure and is fixedly connected to the pump base 7.

[0028] Understandably, this application does not limit the specific shape of the support traction plate 1. The support traction plate 1 can be triangular, trapezoidal, or square, etc. In order to facilitate the use of the equipment, the support traction plate 1 can also be provided with holes or slots or other structures.

[0029] Of course, in some possible embodiments, the adjusting screw 6 is not limited to one; two or more adjusting screws 6 can also be provided. Multiple adjusting screws 6 can be threadedly connected to the same support traction plate 1, or threadedly connected to two support traction plates 1 respectively. The end of the adjusting screw 6 near the slider 5 is rotatably connected to the slider 5. In practice, rotating multiple adjusting screws 6 simultaneously can adjust the movement of the support traction plate 1.

[0030] Preferably, in this embodiment, a first nut 61 is provided on the outer side of the support traction plate 1. The first nut 61 is sleeved on the end of the adjusting screw 6 away from the fixed part and is threadedly connected to the adjusting screw 6. The position of the support traction plate 1 can be locked by tightening the adjusting screw 6 at the outer end.

[0031] Preferably, in this embodiment, a second nut 51 is also provided. The second nut 51 is sleeved on the threaded groove provided on the outer side of the top of the anchor bolt 4 and is threadedly connected to the anchor bolt 4. After the pump moves axially as a whole, the second nut 51 can be screwed onto the top of the anchor bolt 4 to press the slider 5 against the baffle 3, thereby locking the pump after it moves and preventing secondary axial movement.

[0032] Secondly, embodiments of this application also provide a centrifugal feed pump; please refer to [link to relevant documentation]. Figure 2 , Figure 2 This is a three-dimensional structural schematic diagram of the centrifugal feed pump provided in the embodiments of this application. The centrifugal feed pump includes the adjustable support structure as described in any of the above embodiments.

[0033] In some embodiments, several adjustable support structures are provided, which are symmetrically arranged on both sides of the pump base 7 to ensure stable support for the base 7, while enabling the pump to move axially as a whole through the adjustable support structures.

[0034] Preferably, in this embodiment, five adjustable support structures are provided on both sides of the base 7.

[0035] Working principle: When the pump is installed and tightened, it needs to move axially as a whole. At this time, by adjusting the adjusting screw 6 and the first nut 61 connected to the adjusting screw 6, the distance between the slider 5 and the support traction plate 1 is increased, so that the pump set moves axially a certain distance relative to the anchor bolt 4, thereby adjusting the axial position of the pump. After adjustment, the second nut 51 is threaded onto the top of the anchor bolt 4, and the slider 5 is pressed against the baffle 3, so that the pump is locked after movement to prevent secondary axial movement.

[0036] This application utilizes a movable part, a fixed part, and an adjusting screw 6. The movable part connects to the pump base 7, and the fixed end of the fixed part is used to fix the fixed part in place. The movable part of the fixed part connects to a movable groove. Since the movable groove extends parallel to the pump's axis, and the connection between the movable part and the fixed part is made through the adjusting screw 6, the relative position of the movable part and the fixed part can be adjusted by rotating the adjusting screw 6 through the threaded connection between the adjusting screw 6 and the movable part. This allows the movable part to move along the pump's axis on the fixed part, thereby causing the pump assembly to move axially a certain distance relative to the fixed part. After installation, the pump can be axially adjusted as a whole, facilitating the installation and operation of the pump.
