[0031] This utility model proposes a single-stage double-suction centrifugal pump with high stability. The pump body is installed on the base by a locking assembly to ensure that the pump body is stably and firmly installed on the base, effectively preventing loosening between the pump body and the base. In addition, a support assembly is provided on the base so that the pump body can be stably fixed on the ground, thereby improving the stability of the pump body during operation and preventing the pump body from tilting.

[0032] Please see Figures 1 to 4 In one embodiment of this utility model, the highly stable single-stage double-suction centrifugal pump 10 includes:

[0033] Base 1;

[0034] Pump body 2, which is detachably mounted on the base 1;

[0035] Locking assembly 3, the locking assembly 3 being used to mount the pump body 2 onto the base 1;

[0036] Support component 4 is located on the side of the base 1 away from the pump body 2 and is used to fix the base 1 to the ground.

[0037] In this embodiment, the single-stage double-suction centrifugal pump 10 includes a base 1, a pump body 2, and a locking assembly 3. The pump body 2 is stably mounted on the base 1 by the locking assembly 3, thereby ensuring that the pump body 2 and the base 1 are not prone to loosening and ensuring the normal operation of the pump body 2. It should be noted that the single-stage double-suction centrifugal pump 10 also includes a motor 5, which drives the pump body 2 to rotate. The motor 5 is provided with two support feet, and the locking assembly 3 can also be provided on the two support feet to mount the motor 5 on the base 1 by means of the locking assembly 3, thereby avoiding the use of screws or other locking parts 33, and effectively preventing the motor 5 and the base 1 from loosening.

[0038] Specifically, the single-stage double-suction centrifugal pump 10 also includes a support assembly 4, which is located on the side of the base 1 away from the pump body 2. The single-stage double-suction centrifugal pump 10 is installed on the ground by the support assembly 4, so that the pump body 2 can be stably fixed on the ground, thereby improving the stability of the pump body 2 during operation and preventing the pump body 2 from tilting. It should be noted that, in order to further improve the stability of the base 1 installed on the ground, the base 1 can also be installed on the ground with the assistance of locking parts such as screws 33.

[0039] In one implementation, please refer to Figure 1 and Figure 3 The pump body 2 is provided with a connecting seat 21;

[0040] Multiple locking components 3 are provided, and the multiple locking components 3 are spaced apart between the base 1 and the connecting seat 21. Each locking component 3 includes a first clamping member 31, a connecting rod 32 and a locking member 33. One end of the connecting rod 32 passes through the connecting seat 21 and the base 1 in sequence. The first clamping member 31 is movably disposed on one side of the connecting rod 32 that extends out of the connecting seat 21. One end of the locking member 33 passes through the first clamping member 31 and abuts against the connecting rod 32 to lock the first clamping member 31 to the connecting rod 32.

[0041] In this embodiment, the pump body 2 is provided with a connecting seat 21, and the locking assembly 3 includes a first clamping member 31, a connecting rod 32, and a locking member 33. One end of the connecting rod 32 passes through the connecting seat 21 and the base 1 in sequence, and the first clamping member 31 is movably disposed on one side of the connecting rod 32 that extends out of the connecting seat 21. At the same time, one end of the locking member 33 passes through the first clamping member 31 and abuts against the connecting rod 32. Thus, the first clamping member 31 can be fixed at a certain position on the connecting rod 32 by the locking member 33, thereby fixing the connecting seat 21 on the base 1. This achieves stable installation of the pump body 2 on the base 1 and effectively prevents loosening between the pump body 2 and the base 1.

[0042] It should be noted that, in order to ensure the stability between the base 1 and the connecting seat 21, multiple locking components 3 are provided. The multiple locking components 3 are spaced apart between the base 1 and the connecting seat 21 to stably install the connecting seat 21 on the base 1, thereby achieving stable installation of the pump body 2 on the base 1.

[0043] In one implementation, please refer to Figure 1 and Figure 3 Each of the locking components 3 further includes a plurality of plug-in rods 34, which are spaced apart on one side of the first clamping member 31 facing the connecting seat 21.

[0044] The base 1 has a plurality of spaced insertion holes on one side facing the first clamping member 31. Each insertion rod 34 is movably inserted into each insertion hole. Through the cooperation between the insertion rod 34 and the insertion hole, the connecting seat 21 can be effectively installed on the base 1 so that the connecting seat 21 is not easy to move relative to the base 1, thereby ensuring the stability of the pump body 2 installed on the base 1.

[0045] In this embodiment, each locking assembly 3 further includes multiple insertion rods 34, and the multiple insertion rods 34 are spaced apart on the side of the first clamping member 31 facing the connecting seat 21. At the same time, the base 1 also has multiple spaced insertion holes on the side of the first clamping member 31 facing the first clamping member 31. Therefore, when the first clamping member 31 moves toward the connecting seat 21, each insertion rod 34 can be inserted into each insertion hole. Under the locking action of the locking member 33, the first clamping member 31 is locked onto the connecting rod 32, so that the first clamping member 31 can stably fix the connecting seat 21 on the base 1, so that the connecting seat 21 is not easy to move relative to the base 1, thereby ensuring the stability of the pump body 2 installed on the base 1.

[0046] In one implementation, please refer to Figure 1 and Figure 3 The connecting rod 32 has an elongated hole 321 on its outer peripheral wall near the end of the first clamping member 31, and one end of the locking member 33 passes through the first clamping member 31 and abuts against the elongated hole 321.

[0047] In this embodiment, the connecting rod 32 has an elongated hole 321 on the outer peripheral wall near the end of the first clamping member 31. One end of the locking member 33 passes through the first clamping member 31 and abuts against the elongated hole 321, thereby fixing the first clamping member 31 in a certain position so that the first clamping member 31 cannot move, thereby realizing the stable and firm installation of the pump body 2 on the base 1. It should be noted that the locking member 33 is a bolt, and the connection between the locking member 33 and the first clamping member 31 is a threaded connection.

[0048] In one implementation, please refer to Figure 1 and Figure 3Each of the locking components 3 further includes a second clamping member 35, which is fixedly connected to the side of the connecting rod 32 that protrudes from the base 1. Under the mutual clamping of the first clamping member 31 and the second clamping member 35, the connecting seat 21 can be stably and firmly installed on the base 1. The second clamping member 35 is fixedly connected to the side of the connecting rod 32 that protrudes from the base 1. That is, the second clamping member 35 moves with the movement of the connecting rod 32, while the first clamping member 31 moves on the connecting rod 32 and is fixed on the connecting rod 32 by the locking member 33. Thus, under the mutual cooperation of the first clamping member 31 and the second clamping member 35, a stable connection between the connecting seat 21 and the base 1 can be achieved.

[0049] In one implementation, please refer to Figure 1 and Figure 3 The second clamping member 35 has the plug-in rod 34 on one side, and the first clamping member 31 has a through hole on one side facing the connecting seat 21. The plug-in rod 34 is movably inserted into the through hole, so as to further stably install the pump body 2 on the base 1.

[0050] In one implementation, please refer to Figure 2 and Figure 4 The base 1 is provided with an installation groove 11, and multiple support components 4 are provided. Each support component 4 is spaced apart in the installation groove 11. Each support component 4 includes a support plate 41 and multiple support blocks 42. One end of the support plate 41 is installed on the base 1, and multiple support blocks 42 are spaced apart on the side of the support plate 41 away from the base 1. Each support block 42 is provided with multiple spaced support protrusions 421. Each support protrusion 421 can be inserted into the ground, that is, the pump body 2 and the like can be installed on the ground to improve the stability of the pump body 2 during operation and prevent the pump body 2 from tilting.

[0051] In this embodiment, the base 1 is provided with a mounting groove 11, and multiple support components 4 are provided. Each support component 4 is spaced apart within the mounting groove 11. By providing multiple support components 4, the stability of the pump body 2 installed on the ground is improved. Each support component 4 includes a support plate 41 and multiple support blocks 42. One end of the support plate 41 is installed on the base 1, and multiple support blocks 42 are spaced apart on the side of the support plate 41 away from the base 1. Each support block 42 is provided with multiple spaced support protrusions 421. Each support protrusion 421 can be inserted into the ground. It should be noted that each support protrusion 421 has a pointed tip, thus ensuring that each support protrusion 421 can be stably inserted into the ground. Furthermore, to further improve the stability of the base 1 installed on the ground, the base 1 can also be installed on the ground with the assistance of locking components 33 such as screws.

[0052] In one implementation, please refer to Figure 2 and Figure 4 Each of the support components 4 further includes a plurality of friction rollers 43, each of the friction rollers 43 being spaced apart from the support plate 41 and located on one side of the support block 42. By providing a plurality of friction rollers 43, the friction between the support plate 41 and the ground is further increased, thereby reducing the friction between the base 1 and the ground.
