Description

Adjustable impeller structure of centrifugal pump

Technical Field

The utility model relates to a centrifugal pump, in particular to impeller structure with adjustable centrifugal pump.

Background

The centrifugal pump is a pump for conveying liquid by means of centrifugal force generated when an impeller rotates, and water is thrown out by driving water to rotate by utilizing impeller blades rotating at high speed, so that the purpose of conveying is achieved. Before the water pump is started, the pump shell and the water suction pipe are filled with water, then the motor is started, the pump shaft drives the impeller and the water to rotate at a high speed, the water is thrown to the outer edge of the impeller to be thrown into a water pressure pipeline of the water pump through a flow channel of the volute-shaped pump shell. The centrifugal pump has various forms such as vertical type, horizontal type, single stage, multistage, single suction, double suction, self suction and the like. The liquid in the impeller is driven by the blades to rotate together with the blades, and the centrifugal force generated by the rotation makes the liquid move outwards from the center and obtain momentum increment.

The centrifugal pump impeller is main driving piece, sets up the blade on the impeller, and the width of blade depends on the volume of drawing water and work efficiency, and to the occasion of difference, the width of the blade that needs all is different, otherwise the blade is very easy to be damaged, and the width of the blade of present centrifugal pump can not be adjusted as required, only can change the blade of different models, unusual trouble.
