Example (b):

a water pump with a damping function is shown in figures 1 and 2 and comprises a pump body 1, wherein a water inlet pipe 2, a water outlet pipe 4 and a pump shaft 3 are arranged on the pump body 1. The pump shaft 3 is arranged on a seat of the pump shaft 3 in the pump body 1 in a penetrating way, one end of the pump shaft 3 is connected with a motor 6, the other end of the pump shaft 3 is connected with an impeller 7 in a rotating way, an auxiliary impeller 8 is further arranged on the pump shaft 3, and the auxiliary impeller 8 and the impeller 7 are arranged coaxially. The inside wall laminating of the pump body 1 has buffer layer 9, has seted up damping slot 10 on buffer layer 9, and a plurality of has been seted up on buffer layer 9 to damping slot 10.

As shown in fig. 1, in order to reduce the vibration of the pump body 1 during operation, a mounting seat 16 and a support plate 17 are disposed below the pump body 1, and the pump body 1 is connected to the support plate 17 through the mounting seat 16. Four mounting seats 16 are arranged below the pump body 1, and the four mounting seats 16 are respectively and correspondingly arranged at four corners of the pump body 1. The mounting seat 16 comprises a fixing column 18 welded on the lower portion of the pump body 1, a telescopic sleeve 19 welded on the supporting plate 17 and a pressure spring 20, the pressure spring 20 is sleeved on the fixing column 18 and penetrates into the telescopic sleeve 19 at the same time, and the pressure spring 20 is extruded between the pump body 1 and the telescopic sleeve 19.

As shown in fig. 1, the damping groove 10 in the pump body 1 is provided to absorb the impact of the water flow in the pump body, thereby reducing the impact of the water flow directly on the inner side wall of the pump body to form the impact on the pump body, and reducing the possibility of the pump body vibrating. Meanwhile, the auxiliary impeller 8 can share the axial force borne by the pump shaft 3, the pressure at the mechanical seal position is reduced, impurities in liquid are prevented from entering the mechanical seal structure, the abrasion of the mechanical seal grinding block is reduced, and the service life of the water pump is prolonged.

As shown in fig. 1, in order to reduce the phenomenon that impurities in the liquid enter the inside of the pump body 1, the impurities collide with the inside of the pump body 1 to generate vibration, and the pump body 1 vibrates during the working process. The water inlet pipe 2 is communicated with a filter 11, the filter 11 comprises a shell 12, a first filter layer 13 and a second filter layer 14, and the first filter layer 13 and the second filter layer 14 are respectively arranged at the water inlet end and the water outlet end of the shell 12.
