Description

Technical Field

[0001] This utility model belongs to the field of vertical axial flow pump technology, and in particular relates to a vertical axial flow pump set that is easy to teach. Background Technology

[0002] "Currently, large vertical axial flow pumps are bulky and their disassembly and assembly processes are extremely complex, making training often limited to text and images, with very limited practical opportunities." Furthermore, "the impellers, guide vanes, and other main components of large vertical axial flow pumps are often difficult to observe directly in practice." This results in poor training effectiveness for 3D axial flow pump units. Traditional pump unit model manufacturing typically requires multiple processes and complex machining procedures, and this is even more challenging for large vertical axial flow pump models. 3D printing technology allows for the digital modeling of each pump unit component, which can then be printed layer by layer under computer control to ultimately create a complete pump unit model.

[0003] In the current technology, the teaching of three-dimensional axial flow pump sets often achieves the training purpose by manually assembling and disassembling the three-dimensional axial flow pump sets. Since the structure of three-dimensional axial flow pump sets is relatively complex, instructors often need to assemble and explain at the same time during the teaching process, which is not conducive to operation, is prone to operational errors, and affects the teaching quality.

[0004] Furthermore, the manual assembly of the three-dimensional axial flow pump model cannot demonstrate the hierarchical structure of the model, nor can it demonstrate the directional movement of a specific pump model, resulting in low teaching efficiency and hindering students' rapid absorption of the learning content on the three-dimensional axial flow pump model.

[0028] Specifically, the second fixed plate 21 and the fourth fixed plate 23 are both made of transparent material, which is convenient for observing the overall structure of the pump group after the assembly of the multiple components of the pump group.

[0029] The whole vertical shaft flow pump group model is divided into motor assembly, water pump assembly, upper flow passage assembly and lower flow passage assembly according to its function, and is arranged on the upper end surface of the fourth fixed plate 23, the third fixed plate 22, the second fixed plate 21 and the first fixed plate 10 respectively. By moving the second fixed plate 21, the third fixed plate 22 and the fourth fixed plate 23, the pump group assembly on the end surface is moved and assembled with each other, the diversification of teaching content is realized, and the learning efficiency and knowledge absorption efficiency of students are effectively improved.

[0030] Further, as shown in Figure 1 and Figure 6 The lower end surface of the first fixed plate 10 is provided with a plurality of second push cylinders 27, the output end of the second push cylinder 27 is fixedly connected through the first fixed plate 10 and the lower end surface of the second fixed plate 21 and the third fixed plate 22, the upper end surface of the fourth fixed plate 23 is provided with a plurality of first push cylinders 24, the output end of the first push cylinder 24 is fixedly connected through the fourth fixed plate 23 and the upper end surface of the third fixed plate 22 and the second fixed plate 21, a plurality of elastic expansion rods 25 are rotatably arranged on the side wall of the second fixed plate 21 and the third fixed plate 22, the output end of each elastic expansion rod 25 is fixedly provided with a clamping block 28, a plurality of first clamping buckles 26 are fixedly arranged on the side wall of the second fixed plate 21, the third fixed plate 22 and the fourth fixed plate 23 and the end surface of the first fixed plate 10, and the clamping block 28 and the first clamping buckle 26 are clamped and matched with each other.

[0031] Specifically, the first push cylinder 24 and the second push cylinder 27 are ordinary hydraulic push cylinders, electric push cylinders and the like, which are prior art and will not be described in detail, the output rod of the first push cylinder 24 and the second push cylinder 27 is slidably connected with the third fixed plate 22, in the teaching process of the pump group model, according to the actual teaching needs, the sliding between the plurality of fixed plates is carried out, so that the pump group assemblies arranged on the fixed plates are assembled and disassembled with each other, thereby achieving a good pump group structure explanation effect.

[0032] The plurality of elastic expansion rods 25 on the side wall of the second fixed plate 21 and the third fixed plate 22 are also rotated, the clamping block 28 arranged at the output end of the elastic expansion rod 25 is clamped on the first clamping buckle 26 on the side wall of the first fixed plate 10, the second fixed plate 21, the third fixed plate 22 and the fourth fixed plate 23, the elastic expansion rod 25 can form a limiting support between two of the fixed plates, and the output end of the first push cylinder 24 and the second push cylinder 27 can adjust the distance between the two fixed plates without limiting support, thereby achieving the purpose of teaching display.

[0033] The elastic telescopic rod 25 is an elastic telescopic rod with adjustable and fixed telescopic stroke, which is a prior art and will not be described in detail. By adjusting the overall length of the elastic telescopic rod 25, the distance between the two fixed plates supported by the elastic telescopic rod 25 can be adaptively controlled according to actual needs after the output end of the elastic telescopic rod 25 is clamped in the corresponding clamping block 28, so that the distance between the pump assembly required for teaching can be controlled according to needs.

[0034] Further, as shown in Figure 1 and Figure 5 , a plurality of rotating seats 29 are arranged on the side walls of the second fixed plate 21 and the third fixed plate 22, and a rotating block 30 is rotatably arranged in each rotating seat 29.

Then start the plurality of first push cylinders 24 or the second push cylinders 27, so that the output end drives the corresponding fixed plate to move. Due to the limiting arrangement of the elastic telescopic rod 25, the pump assembly to be observed will not be combined, and the other pump assemblies will be combined and assembled with each other under the driving of the fixed plate, thereby completing the teaching demonstration effect.
