Fountain pump principle

Fountain pump principle, the principle of fountain pump, fountain pump brand, preferred Shanghai Wei Hu fountain pump manufacturers.
    Fountain pump is a submersible pump, pump shell, submersible motor, stainless steel shaft, impeller, bearing and other components. Submersible pump for the single suction fountain pump; submersible motor for the submersible submersible; long-term submerged into the water work, no rust. Impeller is the main part of the fountain pump, but also vulnerable parts, about three months to replace the impeller, which determines the fountain pump flow and head.
Fountain pump is industrial products, the voltage design of 380v and 220v, the general use of fountain pump where, are 380V voltage, so that high-pressure crafts fountain pump, the cost is relatively low pressure to be cheaper, because the high pressure fountain pump Variable power transformer. So the cost of a transformer less cost. High pressure fountain pump is cheap but there is also a drawback, but the safety performance is not as good as low pressure, in the course of the operation if the operation of a slight slip, will produce burned electrical phenomenon. So in the current domestic market, the widespread use of high pressure fountain pump. Part of the high-end use of low-pressure fountain pump. This is the status quo of China, may be with the time, people's awareness will be improved
