Centrifugal pump is a pump that relies on the centrifugal force generated when the impeller rotates to transport liquid. Before the pump is started, the pump casing and suction pipe must be filled with water, and then the motor is started, which makes the pump shaft drive the impeller and water to do high-speed rotational movement, and the water will undergo centrifugal movement and be thrown to the outer edge of the impeller, and flow into the pressure pipe circuit of the pump through the flow channel of the worm-shaped pump casing. Let's introduce the types of centrifugal pumps.
In an off-grid solar system with utility power complementation, there are two primary energy sources: photovoltaic (PV) power generation and utility power. The load is the energy consumption point, while the battery both absorbs and releases electricity for the load. Thus, in an off-grid system, the load can be powered by three sources: mains, battery priority, and photovoltaic. Additionally, there are four battery charging modes: photovoltaic priority charging, mains priority charging, photovoltaic independent charging, simultaneous charging of mains and photovoltaics. The application scenarios and requirements of photovoltaic off-grid users vary significantly, so different modes should be selected based on actual needs to maximize photovoltaic use and meet customer requirements.
