Technical Field

[0001] This utility model belongs to the field of water conservancy engineering, specifically relating to a double-layer noise reduction and vibration damping shell for submersible axial flow pumps. Background Technology

[0002] Submersible axial flow pumps are horizontal pumps with low head and high flow rate. They adopt a coaxial pump and motor with a bulb-type structure. They combine submersible motor technology and axial flow pump technology, which not only maintains the advantages of axial flow pumps, but also utilizes submersible motor technology to overcome the problems of motor cooling, heat dissipation, and sealing in traditional axial flow pumps. Submersible axial flow pumps are characterized by convenient installation, stable operation, and strong adaptability, and have been widely used in many fields.

[0003] Traditional submersible axial flow pumps in the prior art often generate significant noise during operation due to the rotation of the impeller and the power of the drive components, which can disturb the surrounding environment and people. Submersible axial flow pumps also generate vibration during operation, which can not only affect the stability and lifespan of the equipment, but may also damage the surrounding environment.

[0004] Therefore, in practical use, existing submersible cross-flow pumps suffer from problems such as high noise and vibration, which affect their operation and service life. Utility Model Content

[0005] To overcome the problems of high noise and vibration affecting the operation and service life of existing submersible axial flow pumps, a double-layer noise reduction and vibration damping shell for submersible axial flow pumps is proposed.

A vacuum groove is opened at one end of the connecting ring and the first connecting shell that are close to each other. A support block with stable support is provided at the lower end of the water inlet shell. A support base and a triangular groove of No. A are respectively opened through the left and right ends of the support block.

[0007] Preferably, the rear end of the first connecting shell is provided with a second connecting shell, and the rear end of the second connecting shell is fixedly connected with a drainage shell.

[0009] Preferably, a second groove is provided through the upper and lower ends of the support frame, and a rubber ring is provided around the lower end of the support frame at the position of the second groove.

[0012] Preferably, the lower end of the soundproof shell is fixed with multiple placement blocks, and the front and rear ends of the placement blocks are fixed with locking posts, which are compatible with the first groove.

[0013] The beneficial effects of this utility model are as follows: the sound generated by the motor inside the first connecting shell is weakened by the connecting ring fixed to the first connecting shell.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-5This utility model provides an embodiment of a submersible axial flow pump with a double-layer noise reduction and vibration damping housing, including a water inlet shell 1; it also includes a connecting ring 18 and a vibration damping mounting assembly. A first connecting shell 2 is provided at the rear end of the water inlet shell 1. A connecting ring 18 for sound insulation is fixed to the outer wall of the first connecting shell 2. A vacuum groove 19 is opened at the end of the connecting ring 18 and the first connecting shell 2 that are close to each other. A support block 12 for stable support is provided at the lower end of the water inlet shell 1. A support base 11 and a triangular groove 13 of type A are respectively opened through the left and right ends of the support block 12. The sound generated by the motor in the first connecting shell 2 is weakened by the connecting ring 18 fixed to the first connecting shell 2. Specifically, the sound is isolated by the vacuum groove 19 opened at the end of the connecting ring 18 and the first connecting shell 2 that are close to each other. With the subsequent vibration damping mounting assembly, the vibration generated during operation can be reduced.

[0022] Please see Figures 1-3 In this embodiment, a second connecting shell 3 is provided at the rear end of the first connecting shell 2, and a drainage shell 4 for drainage is fixedly connected to the rear end of the second connecting shell 3. The water inlet shell 1, the first connecting shell 2, the second connecting shell 3 and the drainage shell 4 form the shell structure of the cross-flow pump. A vibration damping mounting assembly is provided at the lower end of the outer wall of the first connecting shell 2 and the second connecting shell 3. The vibration damping mounting assembly includes a support frame 5, a first groove 6, a second groove 7 and a rubber ring 8. A support frame 5 is fixedly connected to the lower end of the arc-shaped outer wall of the first connecting shell 2 and the lower end of the arc-shaped outer wall of the second connecting shell 3. The first groove 6 is opened through the front and rear ends of the support frame 5. The outer walls of the water inlet shell 1, the first connecting shell 2, the second connecting shell 3 and the drainage shell 4 are jointly fitted with a sound insulation shell 15, which is made of sound-absorbing sponge.

[0023] Please see Figures 3-5 In this embodiment, the upper and lower ends of the support frame 5 are provided with second grooves 7. A rubber ring 8 is provided around the lower end of the support frame 5 at the position of the second groove 7. When a bolt passes through the second groove 7, the rubber ring 8 is fitted around the bolt. The rubber ring 8, located at the middle position where the lower end of the support frame 5 contacts the ground, increases friction while reducing vibration and noise during operation. A support pad 9 is fixedly connected to the lower end of the water inlet shell 1, and a... Connecting block 10 and support base 11, support block 12 is fixedly connected to the lower end of water inlet shell 1, support block 12 and triangular groove 14 of No. B are opened through the left and right ends of support block 12. The strength and stability of support block 12 can be improved by the triangular groove 13 of No. A and triangular groove 14 of No. B on support block 12. Multiple placement blocks 16 are fixedly connected to the lower end of soundproof shell 15, and locking posts 17 are fixedly connected to the front and rear ends of placement block 16. The locking posts 17 are adapted to the first groove 6.

[0024] During operation, the sound generated by the motor inside the first connecting shell 2 is weakened by the connecting ring 18 fixed to the first connecting shell 2. Specifically, the sound is isolated by the vacuum groove 19 opened in the end of the connecting ring 18 and the first connecting shell 2 that are close to each other. A rubber ring 8 is set below the support frame 5. After the bolt passes through the second groove 7, the rubber ring 8 is put around the bolt. The rubber ring 8 in the middle position where the lower end of the support frame 5 contacts the ground increases the friction and reduces the vibration and noise generated during operation. Then, the soundproof shell 15 is put on the overall periphery of the device. The two locking posts 17 of the placement block 16 below the soundproof shell 15 are snapped into the first groove 6 to realize the installation of the soundproof shell 15 in the overall device. In order to prevent the water inlet shell 1 and the drain shell 4 from being suspended and vibrating during use, a support structure is set below each of them. The support block 12 at the lower end of the water inlet shell 1 has two triangular structures cut out to provide stability during support.
