A water pump is a machine that delivers or pressurizes a liquid. It transmits mechanical energy or other external energy of prime mover to liquid to increase energy of liquid, and is mainly used for conveying liquid including water, oil, acid-alkali liquor, emulsion, suspension emulsion and liquid metal. After the water pump runs, under the action of centrifugal force generated by high-speed rotation of the impeller, water in the impeller runner is thrown to the periphery and is pressed into the volute, vacuum is formed at the inlet of the impeller, and water in the water tank is sucked along the water suction pipe under the external atmospheric pressure to supplement the space. The sucked water is thrown out by the impeller and enters the water outlet pipe through the volute. In order to ensure that the water pump works normally, the water pump needs to be fixed, vibration generated by the water pump can be transmitted to the support, if the support can not buffer the transmitted vibration, the water pump and the support are easy to resonate, and the fixability of the support to the water pump is reduced.
