Three-dimensional small-amount water injection centrifugal pump

Abstract

The invention discloses a three-dimensional small-amount water injection centrifugal pump, and relates to the technical field of centrifugal pumps. The three-dimensional small-amount water injection centrifugal pump comprises a machine body, a mounting plate and a mounting frame, wherein the bottom of the machine body is fixedly connected with the mounting plate, the top of the mounting frame is movably connected with connecting plates through telescopic rods, and the tops of the connecting plates are fixedly connected with limiting barrels. According to the three-dimensional small-amount water injection centrifugal pump, when the machine body vibrates, the four telescopic rods stretch out and draw back along with the vibration, when one connecting plate moves in one direction, the two adjacent connecting plates are driven to move in the opposite directions through two side rods adjacent to the connecting plate, then the other connecting rod is driven to move in the same direction through the other two side rods, the two connecting rods on the diagonal line move in the same direction, a supporting plate is kept in a horizontal state, when the supporting plate moves up and down, second springs provide elastic force for the supporting plate, the vibration reduction purpose is achieved, and the problem that a common centrifugal pump does not have the vibration reduction function is solved.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a three-dimensional small amount of water injection centrifugal pump. Background technique [0002] The centrifugal pump works by rotating the impeller to make the water centrifugally move. Before the pump is started, the pump casing and the suction pipe must be filled with water, and then the motor is started so that the pump shaft drives the impeller and the water to rotate at a high speed, and the water is centrifugally Movement, being thrown to the outer edge of the impeller, flowing into the pressure water pipeline of the pump through the flow channel of the volute pump casing, the centrifugal is actually the performance of the inertia of the object, such as the water droplets on the umbrella, when the umbrella rotates slowly, the water droplets will follow the rotation of the umbrella, This is because the friction between the umbrella and the water drop acts as th...
