Description

Technical Field

[0001] This utility model relates to the field of pump housing technology, specifically to a low-noise pump housing assembly. Background Technology

[0002] As the core component of fluid machinery such as centrifugal pumps, the pump casing mainly undertakes the functions of medium energy conversion and structural pressure bearing. The pump casing structure is divided into two types: single casing and double casing. Among them, the inner pump casing of the double casing mud pump is responsible for flow and wear resistance, while the outer pump casing is used for pressure bearing and support.

[0003] Existing low-noise pump housings, such as the low-noise and easy-to-install water pump housing disclosed in publication number CN214007481U, have the advantage of reducing pump housing vibration and noise through the cooperation of base, groove, buffer spring, arc block and bolt. However, the outer end of this pump housing does not have a noise cancellation structure, which makes its noise reduction effect poor. Therefore, we propose a low-noise pump housing assembly. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: The low-noise pump housing assembly includes: an inner housing and a noise reduction component; the noise reduction component includes a sound-absorbing cotton sleeve movably installed at the outer end of the inner housing, a soundproof cover movably installed at the outer end of the sound-absorbing cotton sleeve, a front sound-absorbing cotton cylinder fixedly installed at the front end of the sound-absorbing cotton sleeve, a front soundproof cylinder fixedly installed at the front end of the soundproof cover, a fixed base fixedly installed at the lower end of the soundproof cover, an installation cavity opened at the bottom of the fixed base, and a rubber pad movably installed inside the installation cavity.

[0006] Preferably, the four corners of the fixing base and the four corners of the rubber pad are respectively provided with a first fixing hole and a second fixing hole.

[0007] Preferably, an upper soundproofing cylinder is fixedly installed on the upper end of the soundproofing cover, and an upper sound-absorbing cotton cylinder is fixedly installed on the inner wall of the upper soundproofing cylinder.

[0008] Preferably, the upper end of the sound-absorbing cotton sleeve is also provided with a round hole.

[0009] Preferably, the upper end of the inner shell is provided with an upper threaded hole, in which an upper drain pipe is movably installed, and the front end of the inner shell is provided with a front threaded hole, in which a front water pipe is movably installed.

[0010] Preferably, a sealing ring is movably installed on one side of both the upper drain pipe and the inlet water pipe.

[0011] Preferably, the inner shell and the soundproof cover are respectively provided with a first mounting hole and a second mounting hole.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. In this utility model, the sound-absorbing cotton sleeve and the sound insulation cover are installed sequentially on the outer end of the inner shell, and the upper sound-absorbing cotton cylinder, the upper sound insulation cylinder, the front sound-absorbing cotton cylinder and the front sound insulation cylinder are installed on the outer end of the upper drain pipe and the front water pipe. This can form a wrap-around sound insulation protection for the entire pump shell, thereby improving the noise reduction effect of the pump shell during use. Moreover, the modular inner shell, the upper drain pipe and the front water pipe, as well as the modular sound-absorbing cotton sleeve and the sound insulation cover in the noise reduction component, make it easy to disassemble and replace any damaged parts of the pump shell assembly during use, thereby avoiding the scrapping of the whole assembly. 2. In this utility model, the rubber pad installed in the lower fixing seat of the soundproof cover can reduce the resonance between the pump casing and the ground or metal frame when the pump casing is installed on the ground or metal frame, thereby reducing the noise caused by vibration during use.

[0017] Combination Figure 1-5 As shown, the low-noise pump housing assembly provided by this utility model includes: an inner housing 100 and a noise reduction component 200; the noise reduction component 200 includes a sound-absorbing cotton sleeve 201 movably installed at the outer end of the inner housing 100, a soundproof cover 202 movably installed at the outer end of the sound-absorbing cotton sleeve 201, a front sound-absorbing cotton cylinder 203 fixedly installed at the front end of the sound-absorbing cotton sleeve 201, a front soundproof cylinder 204 fixedly installed at the front end of the soundproof cover 202, a fixing seat 205 fixedly installed at the lower end of the soundproof cover 202, an installation cavity 206 opened at the bottom of the fixing seat 205, and a rubber pad 207 movably installed in the installation cavity 206. A first fixing hole 208 and a second fixing hole 207 are respectively opened at the four corners of the fixing seat 205 and the four corners of the rubber pad 207. The upper soundproof cylinder 210 is fixedly installed on the upper end of the soundproof cover 202, and the upper sound-absorbing cotton cylinder 211 is fixedly installed on the inner wall of the upper soundproof cylinder 210. The upper end of the sound-absorbing cotton sleeve 201 is also provided with a round hole 212. The upper end of the inner shell 100 is also provided with an upper threaded hole 213. An upper drain pipe 214 is also movably installed in the upper threaded hole 213. A front threaded hole 215 is also provided at the front end of the inner shell 100. A front water pipe 216 is also movably installed in the front threaded hole 215. A sealing ring 217 is movably installed on one side of both the upper drain pipe 214 and the front water pipe 216. The inner shell 100 and the soundproof cover 202 are respectively provided with a first mounting hole 218 and a second mounting hole 219.

[0018] Specifically, the pump casing, as a core component of fluid machinery such as centrifugal pumps, primarily undertakes the functions of medium energy conversion and structural pressure bearing. The inner casing 100 is sequentially fitted with a sound-absorbing cotton sleeve 201 and a sound insulation cover 202. The upper sound-absorbing cotton cylinder 211, upper sound insulation cylinder 210, front sound-absorbing cotton cylinder 203, and front sound insulation cylinder 204 installed at the outer ends of the upper drain pipe 214 and the inlet water pipe 216, respectively, form a wraparound sound insulation protection for the entire pump casing, thereby improving the noise reduction effect during use. Furthermore, the modular inner casing 100, upper drain pipe 214, and inlet water pipe 216, as well as the modular sound-absorbing cotton sleeve 201 and sound insulation cover 202 in the noise reduction assembly 200, allow for easy disassembly and replacement of any damaged component in the pump casing assembly, thus avoiding complete scrapping. The sound insulation cover 201... The rubber pad 207 installed inside the lower fixing seat 205 allows the pump casing to be installed on the ground or metal frame, reducing resonance between the pump and the ground or metal frame, thereby reducing noise caused by vibration during use. The first fixing hole 208 and the second fixing hole 209 correspondingly opened on the fixing seat 205 and the rubber pad 207 are mainly used to fix the fixing seat 205 and the rubber pad 207 together. The sealing ring 217 installed at one end of the upper drain pipe 214 and the inlet water pipe 216 are mainly used to ensure the sealing of the upper drain pipe 214 and the inlet water pipe 216 after installation in the inlet water pipe 216 and the front threaded hole 215. The second mounting hole 219 and the first mounting hole 218 correspondingly opened between the soundproof cover 202 and the inner shell 100 are mainly used to fix them together after installation.

[0019] Working principle and usage process of this utility model: During use, the outer end of the inner casing 100 is constantly protected by the sound-absorbing cotton sleeve 201 and the sound insulation cover 202. At the same time, the outer ends of the front and upper ends of the inlet water pipe 216 and the upper drain pipe 214, which are used for water inlet and drainage respectively, are also constantly protected by the front sound-absorbing cotton cylinder 203, the front sound insulation cylinder 204, the upper sound-absorbing cotton cylinder 211, and the upper sound insulation cylinder 210. In this way, the pump casing is completely wrapped with sound-absorbing and noise-reducing protection to ensure low noise during use. In addition, the rubber pad 207 installed at the bottom of the fixing seat 205 at the lower end of the sound insulation cover 202 can also reduce the resonance when the fixing seat 205 is fixed to the ground or the upper end of the metal frame, thereby reducing the noise generated by vibration during use.
