Description

Technical Field

[0001] This utility model relates to the field of vacuum pump impeller reinforcement technology, and more specifically, to a cavitation-resistant gas conveying water ring vacuum pump impeller reinforcement device. Background Technology

[0002] The inlet and outlet of the open-face vacuum pump are designed and installed on the pump body. The entire impeller is cast in one piece, and the end face of the impeller is reinforced in a ring, making the impeller structure very robust. The pump can effectively resist the destructive effects of water hammer and metal entrained in the working fluid.

[0003] When using a gas delivery water ring vacuum pump impeller with cavitation resistance, it needs to deliver gas through pressurization and impact. However, due to the central joint of the outer casing of the vacuum pump impeller, it is difficult to strengthen the joint. This makes it easy for the joint to loosen and deform later, resulting in poor gas delivery and cavitation problems. Therefore, a cavitation-resistant gas delivery water ring vacuum pump impeller reinforcement device is needed. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a cavitation-resistant impeller reinforcement device for a gas conveying water ring vacuum pump, comprising an impeller housing, an outlet fixedly connected to one side of the outer wall of the impeller housing for gas discharge, and a reinforcing component installed on the other side of the outer wall of the impeller housing, the reinforcing component comprising: A reinforcing rib is fixedly installed on the other side of the outer wall of the impeller housing, and the outer wall of the reinforcing rib is fixed with multiple reinforcing buckles. An embedding groove is formed in the inner wall of the reinforcing buckle, and the embedding groove is used to position the reinforcing rib; A reinforcing strip is fixedly located on the upper surface of the reinforcing buckle. Reinforcing blocks are fixed at both ends of the reinforcing strip, and an outer ring is fixedly installed at the bottom end of the reinforcing block. The inner ring is fixedly installed on the inner wall of the outer ring, and both the outer ring and the inner ring are used to fix and reinforce the impeller housing.

[0005] In a preferred embodiment, the vertical cross-sectional shape of the reinforcing rib is arc-shaped, and both the reinforcing rib and the reinforcing buckle are made of tungsten alloy.

[0006] In a preferred embodiment, the reinforcing block, the outer ring, and the inner ring are all made of tungsten alloy. Both the outer ring and the inner ring have circular cross-sectional shapes, and the inner diameter of the outer ring is larger than that of the inner ring.

[0007] In a preferred embodiment, the inner ring is provided with a plurality of inclined blocks; Each of the inclined blocks is fixedly connected to the impeller housing. A fixing ring is installed at one end of each inclined block. An inlet is fixedly connected to the inner wall of the fixing ring, and the inlet is fixedly connected to the impeller housing. An arc-shaped strip is fixed between each pair of adjacent inclined blocks.

[0008] In a preferred embodiment, the plurality of the inclined blocks are arranged in a circular, equidistant distribution, with gaps formed between adjacent inclined blocks.

[0009] In a preferred embodiment, the vertical cross-sectional shape of the fixing ring is annular, and the plurality of arc-shaped strips are arranged in an equidistant circular pattern.

[0010] The technical effects and advantages of this utility model are as follows: 1. This utility model adopts a reinforcing component, with an inner ring supporting an outer ring, and the outer ring supporting a reinforcing block. The reinforcing block provides support and reinforcement for the reinforcing strip. The embedded groove on the inner wall of the reinforcing buckle can position the reinforcing rib. The inner ring, outer ring, reinforcing block, reinforcing strip, and reinforcing buckle are all made of tungsten alloy, which increases the symmetrical reinforcement force on both sides of the impeller shell, so that the impeller shell will not deform, ensuring smooth gas transport inside the impeller shell and better cavitation resistance. 2. This utility model uses multiple inclined blocks to reinforce and support the fixed ring in a circular distribution, and the arc strip between two adjacent inclined blocks can provide reinforcement. Multiple inclined blocks stably reinforce the fixed ring in a circumferential distribution, preventing impact deformation damage to the inlet edge and enhancing the inlet's resistance to deformation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1-4 The impeller reinforcement device for a gas conveying water ring vacuum pump shown is equipped with a reinforcing component. The reinforcing component ensures that the inner ring 9, outer ring 8, reinforcing block 7, reinforcing strip 6, and reinforcing buckle 4 are all made of tungsten alloy, increasing the symmetrical reinforcement force on both sides of the impeller shell 1. This prevents the impeller shell 1 from deforming, ensures smooth gas transport inside the impeller shell 1, and improves cavitation resistance. The specific structural configuration of the reinforcing component is as follows.

[0018] In this embodiment, as Figures 1-2 As shown, an outlet 2 is fixedly connected to one side of the outer wall of the impeller housing 1 for air discharge. A reinforcing assembly is installed on the other side of the outer wall of the impeller housing 1. The reinforcing assembly includes: a reinforcing rib 3, which is fixedly installed on the other side of the outer wall of the impeller housing 1, and multiple reinforcing buckles 4 are fixed to the outer wall of the reinforcing rib 3; an embedding groove 5, which is opened on the inner wall of the reinforcing buckle 4 and is used to position the reinforcing rib 3; a reinforcing strip 6, which is fixedly located on the upper surface of the reinforcing buckle 4, and a reinforcing block 7 is fixed to both ends of the reinforcing strip 6. An outer ring 8 is fixedly installed at the bottom end of the reinforcing block 7; and an inner ring 9, which is fixedly installed on the inner wall of the outer ring 8. Both the outer ring 8 and the inner ring 9 are used to fix and reinforce the impeller housing 1. The vertical cross-section of the reinforcing rib 3 is arc-shaped. The reinforcing rib 3 and the reinforcing buckle 4 are both made of tungsten alloy. The reinforcing block 7, the outer ring 8, and the inner ring 9 are all made of tungsten alloy. The vertical cross-section of the outer ring 8 and the inner ring 9 are both annular. The inner diameter of the outer ring 8 is larger than the inner diameter of the inner ring 9.

[0019] In use, the anti-cavitation gas conveying water ring vacuum pump impeller reinforcement device of this technology uses an inner ring 9 to support an outer ring 8, which in turn supports a reinforcement block 7. The reinforcement block 7 provides support and reinforcement for the reinforcing strip 6, and the reinforcing strip 6 provides support and reinforcement for the reinforcement buckle 4. The embedded groove 5 on the inner wall of the reinforcement buckle 4 can position the reinforcing rib 3. Thus, the reinforcing rib 3 can be stably limited after being positioned by the two reinforcement buckles 4. Since the inner ring 9, outer ring 8, reinforcement block 7, reinforcing strip 6, and reinforcement buckle 4 are all made of tungsten alloy, they can provide firm reinforcement for the reinforcing rib 3. The reinforcing rib 3 can also reinforce the gaps in the die-cast impeller shell 1 and increase the symmetrical reinforcement force on both sides of the impeller shell 1.

[0020] In this embodiment, as Figures 2-4As shown, the inner ring 9 has multiple inclined blocks 10 inside; each inclined block 10 is fixedly connected to the impeller housing 1, and a fixing ring 11 is installed at one end of each inclined block 10. An inlet 12 is fixedly connected to the inner wall of the fixing ring 11, and the inlet 12 is fixedly connected to the impeller housing 1; an arc-shaped strip 13 is fixed between each adjacent inclined block 10. The multiple inclined blocks 10 are arranged in a circular ring at equal intervals, and gaps are formed between adjacent inclined blocks 10. The vertical cross-section of the fixing ring 11 is circular, and the multiple arc-shaped strips 13 are arranged in a circular ring at equal intervals.

[0021] In use, the anti-cavitation gas conveying water ring vacuum pump impeller reinforcement device of this technology supports multiple inclined blocks 10 through the impeller shell 1. The multiple inclined blocks 10 can be distributed in a ring to reinforce and support the fixed ring 11. Moreover, the arc strip 13 between two adjacent inclined blocks 10 can provide reinforcement, thereby ensuring that the multiple inclined blocks 10 stably achieve circumferential reinforcement of the fixed ring 11. The fixed ring 11 provides reinforcement to the outer wall of the inlet 12.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
