An adjustable pump with an adjusting device for changing the water inlet direction of the impeller

Abstract

The invention provides an adjustable pump with an adjusting device for changing an impeller inflow direction. The adjustable pump with the adjusting device for changing the impeller inflow direction comprises a driving shaft and an impeller sleeves at the driving shaft; the impeller comprises a fluid inlet channel, and both sides of the impeller are respectively provided with fluid adjusting devices; each of the fluid adjusting device comprises a main gear rotated by taking the driving shaft as an axis, a rotating rod for pushing the main gear to rotate, a secondary gear meshed with the main gear and a water baffle held in the fluid inlet channel of the impeller; the water baffle and the secondary gear are rotated synchronously.

Description

technical field [0001] The invention relates to pumps, in particular to an adjustable pump with an adjusting device for changing the water inlet direction of the impeller. Background technique [0002] In order to adapt to different working conditions, the pump often needs to change the output flow of the pump. The main factors affecting the output flow of the pump are as follows: one is the speed of the impeller; the other is the width of the impeller; the third is the inlet flow of the impeller Flow direction, flow velocity and flow rate of the fluid in the channel. At present, changing the output flow of the pump on the market is mainly achieved by changing the impeller speed. This method usually needs to replace the motor or add a frequency converter to adjust the impeller speed, which is inconvenient to operate. However, by changing the impeller width There is no way to adjust the method. As for the third adjustment method, a regulating valve is usually installed at th...

At present, changing the output flow of the pump on the market is mainly achieved by changing the impeller speed. This method usually needs to replace the motor or add a frequency converter to adjust the impeller speed, which is inconvenient to operate. However, by changing the impeller width There is no way to adjust the method. As for the third adjustment method, a regulating valve is usually installed at the fluid inlet of the pump to control its input flow, which only changes the fluid input volume, and cannot change the fluid flow direction and flow rate. The flow adjustment range of the method is limited and the accuracy is not high
