Description

Technical Field

[0001] This utility model relates to the field of guide vane mixed flow pump technology, and in particular to a simple installation guide vane for a guide vane mixed flow pump. Background Technology

[0002] Mixed-flow pumps, also known as guide vane pumps, offer advantages such as small footprint, small outer diameter, easy start-up, and high efficiency. They are a type of pump with performance and structure falling between centrifugal and axial-flow pumps, compensating for the shortcomings of both while possessing their advantages. Mixed-flow pumps have a specific speed range of 290–590 RPM, and their applications are gradually expanding to other pump types. As a high-specific-speed impeller pump, mixed-flow pumps are widely used not only in agricultural irrigation and drainage, sewage treatment, and flood control, but also in cooling systems and power plants.

[0003] The existing technical solutions mentioned above have the following drawbacks: the guide vanes inside the existing guide vane mixed flow pumps are all integral structures. When some vanes are damaged, they need to be replaced, which is costly to replace the whole thing. It is also inconvenient to disassemble and replace the entire part. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-install guide vane for a guide vane type mixed flow pump.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The guide vane of the guide vane type mixed flow pump includes a mounting base, a fixing seat is provided inside the mounting base, a groove is reserved on the outer side of the fixing seat, a positioning hole and a threaded hole are opened on the outer side of the groove inside the fixing seat, a support block is fixedly connected to the inner side of the mounting base, and a connecting rod is provided between the mounting base and the fixing seat.

[0007] By adopting the above technical solution, a groove is added inside the original mounting base for installing the guide vanes, which can change the original fixed structure into a replaceable structure. It can be installed and disassembled as needed, and only the replacement part needs to be replaced.

[0008] Furthermore, a fixing component is provided inside the groove, and a countersunk hole is provided inside the fixing component. A positioning pin is fixedly connected to one side of the fixing component, and a bolt is inserted into the countersunk hole. A connecting plate is fixedly connected to the other side of the fixing component, and a guide vane is fixedly connected to the outside of the connecting plate.

[0009] By adopting the above technical solution, bolts are added for threaded connection, which facilitates the fixing of the fastener. At the same time, in order to improve the stability of the fastener after installation, locating pins can be added for positioning, thereby improving stability and accuracy.

[0010] Furthermore, one end of the connecting rod is fixedly connected to the inner side of the mounting base, and the other end of the connecting rod is fixedly connected to the outer side of the fixed base. Multiple support blocks are evenly distributed in a ring.

[0011] By adopting the above technical solution and adding multiple sets of support blocks, support blocks can be added at the position where the guide vane contacts the mounting base on the outside, which can play an auxiliary support role in resisting the impact of water flow.

[0012] Furthermore, the grooves, positioning holes, and threaded holes are distributed in multiple sets at equal intervals in a ring, with two positioning holes in each set.

[0013] By adopting the above technical solution, and by adding multiple sets of detachable structures, each guide vane is designed to be detachable and replaceable.

[0014] Furthermore, the fixing component, countersunk hole, positioning pin, bolt, connecting plate and guide vane are distributed in multiple groups at equal intervals in a ring. Each group has two positioning pins. The connecting plate fits against the outer side of the fixing seat. The fixing component engages with the groove. The positioning pin engages with the positioning hole. The bolt passes through the countersunk hole and extends into the threaded hole. The bolt and the threaded hole are threadedly connected. The guide vane adopts an inclined structure.

[0015] By adopting the above technical solution, the blades are locked and fixed by bolt connection, which facilitates installation and disassembly.

[0016] In summary, the beneficial technical effects of this utility model are as follows:

[0017] It adopts grooves, positioning holes, threaded holes, fasteners, positioning pins, and guide vanes. By designing the original fixed vane structure into a detachable structure, the fasteners can be installed with the grooves, and then the vanes can be fixed with the connecting plate on the outside of the fasteners. This allows the guide vanes to be disassembled and installed at any time. During installation, the guide vanes can be further supported by the outer support blocks to improve the stress effect of the vanes and effectively resist the impact of water flow. Once the vanes are damaged, the damaged parts can be removed, resulting in convenient installation and use. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1-3 The simplified installation guide vane of the guide vane type mixed flow pump includes a mounting base 1, a fixing base 2 inside the mounting base 1, a groove 3 reserved on the outer side of the fixing base 2, a positioning hole 4 and a threaded hole 5 on the outer side of the groove 3 inside the fixing base 2, a support block 6 fixedly connected to the inner side of the mounting base 1, a connecting rod 7 between the mounting base 1 and the fixing base 2, a fixing component 8 inside the groove 3, a countersunk hole 9 inside the fixing component 8, a positioning pin 10 fixedly connected to one side of the fixing component 8, a bolt 11 inserted into the countersunk hole 9, a connecting plate 12 fixedly connected to the other side of the fixing component 8, and a guide vane fixedly connected to the outer side of the connecting plate 12. The blade 13 has a groove 3 added inside the original mounting base 2 for installing the guide vane, which can change the original fixed structure into a replaceable structure. It can be installed and disassembled as needed, and only the replacement part needs to be replaced. Bolts 11 are added for threaded connection to facilitate the fixation of the fixing component 8. At the same time, in order to improve the stability of the fixing component 8 after installation, positioning pins 10 can be added to improve stability and accuracy. By adding multiple sets of support blocks 6, support blocks 6 can be added at the contact position between the guide vane 13 and the mounting base 1, which can play an auxiliary support role to resist the impact of water flow.

[0024] like Figure 1-3 As shown, one end of the connecting rod 7 is fixedly connected to the inner side of the mounting base 1, and the other end of the connecting rod 7 is fixedly connected to the outer side of the fixed base 2. The support blocks 6 are distributed in multiple rings at equal intervals. The grooves 3, positioning holes 4 and threaded holes 5 are distributed in multiple rings at equal intervals. Each group of positioning holes 4 has two. The fixing parts 8, countersunk holes 9, positioning pins 10, bolts 11, connecting plates 12 and guide vanes 13 are distributed in multiple rings at equal intervals. Each group of positioning pins 10 has two. The connecting plate 12 is in contact with the outer side of the fixed base 2. The fixing parts 8 are engaged with the grooves 3. The positioning pins 10 are engaged with the positioning holes 4. The bolts 11 pass through the countersunk holes 9 and extend into the interior of the threaded holes 5. The bolts 11 and the threaded holes 5 are threadedly connected. The guide vanes 13 adopt an inclined structure.

[0025] The implementation principle of this embodiment is as follows: When the guide vane 13 needs to be replaced, the bolt 11 can be loosened, the fixing part 8 can be taken out from the groove 3, and then the new guide vane 13 and the fixing part 8 can be installed together. During installation, the positioning pin 10 at the bottom of the fixing part 8 can be inserted into the positioning hole 4 to achieve positioning installation. Then, the bolt 11 is used to lock and fix it. The structure is simple, easy to disassemble and assemble, and the damaged part can be replaced at any time without the need for overall disassembly and replacement. This saves costs and improves maintenance efficiency.
