Background technique

Centrifugal pumps work by rotating the impeller to cause the water to move centrifugally. Before starting the pump, the pump casing and the suction pipe must be filled with water, and then the motor is started to drive the impeller and the water to rotate at a high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller, and flows through the volute pump casing. The pressure water pipeline flowing into the water pump. The basic structure of a centrifugal pump is composed of eight parts, namely: impeller, pump body, pump cover, water retaining ring, pump shaft, bearing, sealing ring, stuffing box, and axial force balance device.

Pumps are widely used in power stations, factories, sewage treatment systems, etc., to transport water remotely or to lift water from low altitudes to high altitudes. The application of the pump determines that the pump equipment usually needs to be located underwater for a long time, and often needs to work without interruption. Therefore, it is necessary to develop remote monitoring and control technology for pumps. Accessing the pump via the network is a possible solution.
