The pump body 1 has water inlet port and water outlet port, is equipped with outlet pipe 13 on the water outlet port, and outlet pipe 13 cover is equipped with second damper assembly 3, and this second damper assembly 3 includes second damping piece 31 and locates the second counter weight 32 on second damping piece 31, and second damping piece 31 is the annular and overlaps and locate on outlet pipe 13. The water outlet pipe 13 is bent at one side of the pump body 1, and the outer ring 312 of the second damping member is tightly attached to the housing 12 of the pump body. The water inlet port is provided with a water inlet pipe 14, the water inlet pipe 14 is bent and arranged at the other side of the pump body 1, and the water inlet pipe 14 is also provided with a second damping component 3 so that the two sides of the shell 12 of the pump body are tightly attached to the outer ring 312 of the second damping component. The second damping parts on the two sides have certain damping effect on the shell of the pump body.

When the water outlet pipe 13 vibrates, the inner ring 311 is stressed firstly to obtain primary buffering, and if the vibration is large, the vibration is transmitted to the outer ring 312 to perform secondary buffering, so that the shock absorption is further realized.

The water inlet end of the water inlet pipe 14 on the shell and the water outlet end of the water outlet pipe 13 on the shell are both provided with a buffer damping block 7.

As shown in fig. 4, the second damper 31 includes an inner ring 311 and an outer ring 312 concentrically arranged, the inner ring 311 and the outer ring 312 have a damping gap 314 therebetween and are connected by a radial connecting arm 313, and the second counterweight 32 is provided on the outer ring 312. The second weight 32 is fitted to the outer ring 312 by integral molding. The second weights 32 in this embodiment are three and are uniformly arranged on the outer ring 312.

Referring to fig. 5, a third damping assembly 4 is disposed on the housing 12 of the pump body 1, the third damping assembly 4 includes a third damping member 41 and a third counterweight 42 disposed on the third damping member 41, and the third damping member 41 is annular and is sleeved on the housing 12 of the pump body 1 in a circumferential direction.
