The invention discloses a drainage pressure reduction device for a centrifugal pump. When pressure reduction work is conducted on the centrifugal pump, drainage pressure reduction can be well conducted on the centrifugal pump through the drainage pressure reduction device. Drainage work is conducted according to the actual internal pressure condition of a pump body, and then normal work of the centrifugal pump is guaranteed. Through the arrangement of drainage bodies, pressure limiting springs and pressure reduction staged drainage mechanisms, staged drainage pressure reduction can be conducted on the centrifugal pump. When the internal pressure of the centrifugal pump body is too large, multi-stage drainage can be conducted according to the actual situation of the centrifugal pump body, and then the working efficiency of pressure reduction of the centrifugal pump body can be improved. The internal pressure of the pump body can be quickly recovered to be within a pressure safety use limit value, normal operation of the centrifugal pump is guaranteed, the working efficiency is guaranteed, damage to the centrifugal pump is avoided, and the working economic benefit is guaranteed.
