Detailed Description
In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
The noise-reducing cavitation pump body provided by the embodiment of the utility model is explained. As shown in fig. 1-4, a noise-reducing cavitation pump body comprises a pump main body 1, wherein a pump cover 2 is arranged at the lower end of the pump main body 1, a pump main body water inlet 3 and a pump main body water outlet 4 are formed in the pump cover 2, a cavitation body 5 is arranged at the lower part of the inner side of the pump main body 1, and a damping tube 6 is arranged at the top of the cavitation body 5; the cavitation body 5 is communicated with the water outlet 4 of the pump body through a water outlet pipe 7.
The damping tube 6 is embedded on the damping tube mounting plate 8, and a damping tube water inlet 10 and a damping tube water outlet 11 are respectively formed at the top and the bottom of the damping tube 6. The damping tube mounting plate 8 is arranged in the middle of the inner side of the pump body 1, and a through hole 9 is formed in the center of the damping tube mounting plate 8. The damping tube 6 is a plurality of, and a plurality of damping tubes 6 are distributed circumferentially around the center of the damping tube mounting plate 8.
The inner side of the pump body 1 is provided with an inner cavity A12, an inner cavity B13 and an inner cavity C14, and the space between the damping tube mounting plate 8 and the pump cover 2 is the inner cavity A12. The space above the damper tube mounting plate 8 in the pump body 1 is an inner cavity B13. The top of the inner cavity A12 is communicated with the inner cavity B13 through the through hole 9 of the damping tube mounting plate 8.
The space inside the cavitation body 5 is an inner cavity C14. The side wall of the cavitation body 5 is not in contact with the side wall of the pump body 1, and is spaced apart so that the cavity C14 is located inside the cavity a12 and the water in the cavity a12 is enclosed outside the cavity C14.
The inner cavity B13 is communicated with the inner cavity C14 through the damping tube 6, the inner cavity B13 is communicated with the damping tube water inlet 10, and the damping tube water outlet 11 is communicated with the inner cavity C14; the inner cavity C14 is communicated with the water outlet 4 of the pump body through the water outlet pipe 7.
The motor shaft of the cavitation heat pump is coupled with an impeller, which is located in the center of the inner cavity B13 (the impeller is not shown in fig. 4). When the damper is in operation, the impeller in the inner cavity B13 rotates, so that water in the inner cavity A12 is sucked into the inner cavity B13 through the through hole 9 arranged at the center of the damper pipe mounting plate 8; the water generates high pressure along with the rotation of the impeller in the inner cavity B13, and flows into the damping tube 6 through the damping tube water inlet 10 and flows into the inner cavity C14 through the damping tube water outlet 11, so that the pressure of the water is released; the water forms a high-speed jet when entering the inner cavity C14 from the inner cavity B13 through the damping tube 6, and the high-speed jet generates heat and generates great noise at the water outlet 11 of the damping tube, which is a cavitation phenomenon of the water.
The inner cavity C14 of the noise-reducing cavitation pump body is arranged in the inner cavity A12, and because the inner cavity C14 is arranged in the water in the inner cavity A12, when the high-pressure water flow cavitation is generated after passing through the damping tube 6, the noise is not directly transmitted to the surrounding external environment by the inner cavity C14, but the noise generated in the inner cavity C14 is firstly attenuated by the water in the inner cavity A12 outside the inner cavity C14 and then is transmitted out through the cavity wall of the inner cavity A12; the noise generated by cavitation of the water is attenuated by the water in the inner cavity A12, so that the noise generated by the cavitation heat pump during working can be effectively reduced. Through experiments, the noise of the existing cavitation heat pump is 92-93 db when the noise is directly transmitted to the surrounding environment through the wall of the pump; when the cavitation heat pump adopting the noise-reducing cavitation pump body works, noise generated by cavitation is attenuated by water in the inner cavity A12 and then is transmitted out of 82-83 db through the cavity wall of the inner cavity A12.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
