The invention provides a water pump base with a good damping effect, and relates to the technical field of water pumps. The water pump base with the good damping effect comprises a cushion block, a damping frame is fixedly arranged at the top of the cushion block, a transverse plate is arranged in the damping frame, wheel shafts are fixedly arranged at the two ends of the transverse plate respectively, and rolling wheels are movably connected to the two ends of each wheel shaft. According to the water pump base with the good damping effect, the damping frame, the transverse plate, the rollingwheels, a vertical rod, a supporting rod, a positioning plate, a rotating seat, a stress plate, a first damping spring and a second damping spring are cooperated, when a water pump at the top of a mounting plate runs, the vibration generated from the running of the water pump can be conducted to the transverse plate through the vertical rod, firstly, after the transverse plate is stressed, the transverse plate can enable the supporting rod to downwards extrude the stress plate, and the vibration is buffered through the first damping spring; and meanwhile, the main vibration borne by the transverse plate can be buffered and counteracted through the second damping spring, therefore, the water pump base is good in damping effect, and stable running of the water pump is facilitated.
