Abstract

The invention provides an adjustable pump with an adjusting device for narrowing an impeller outlet. The adjustable pump with the adjusting device for narrowing the impeller outlet comprises a driving shaft, an impeller sleeves at the driving shaft, an elastic piece and a pressure module; the impeller comprises a first impeller and a second impeller which are meshed to each other; the elastic piece is clamped between the first impeller and the second impeller; the pressure module drives the first impeller and / or the second impeller to move along the axial direction of the driving shaft so as to adjust the space between two impellers.

Description

technical field [0001] The invention relates to pumps, in particular to an adjustable pump with a narrowing impeller outlet adjusting device. Background technique [0002] In order to adapt to different working conditions, the pump often needs to change the output flow and pressure of the pump. There are two main factors affecting the output flow and pressure of the pump: one is the speed of the impeller; the other is the width of the impeller. However, changing the output flow and pressure of the pump on the market is mainly achieved by changing the impeller speed, and there is no solution to change the output flow and pressure of the pump by adjusting the width of the impeller. Contents of the invention [0003] Based on the above problems, the present invention provides an adjustable pump with a narrowing impeller outlet adjustment device. [0004] The adjustable pump with a narrowing impeller outlet adjustment device includes a drive shaft, an impeller sheathed on the...
