Abstract

The invention relates to the technical field of water pump equipment, and proposes a centrifugal pump with an on-line adjustable lift, comprising a pump casing with an inlet and outlet, a main shaft rotatably arranged in the pump casing, and an impeller arranged on the main shaft, which is additionally arranged in the pump casing The telescopic casing and the wheel diameter adjustment mechanism are arranged in the telescopic casing. The impeller includes fixed blades and telescopic blades. The telescopic blades are slidably arranged on the fixed blades. The wheel diameter adjustment mechanism includes an adjustment disk and a driving device. The driving device drives the adjustment disk to rotate. , the adjusting disc is provided with a groove that diverges radially outward, and the telescopic blade is provided with a boss extending into the groove. Through the above technical solutions, the problem of difficulty in automatic adjustment of centrifugal pumps in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of water pump equipment, in particular to a centrifugal pump with an on-line adjustable lift. Background technique [0002] With the change of ambient temperature or production load, the circulating water system of industrial and mining enterprises often needs to change the flow and pressure required for production. In the face of this situation, the traditional centrifugal pump has been unable to adapt to the changing situation, because the traditional centrifugal pump The head flow of the pump is fixed. [0003] The parameter adjustment during the operation of the centrifugal pump has always been a key issue in the operation of the pump. In the past, valve regulation and motor speed regulation (including reducer regulation, coupler speed regulation, viscous coupling speed regulation, motor pole logarithmic speed regulation, motor step-down speed regulation, motor infeed speed regulation, etc.) were used r...
