The explosion-proof principle of hermetic electrical equipment is to place electrical equipment or electrical components in a gas-tight enclosure. This casing prevents flammable gases from entering the casing from entering the casing. The mark for hermetic electrical equipment is “hâ€.
PV pumping system is the use of solar modules to solar energy directly into electrical energy, drive motor driven pump device. Mainly divided into submersible pumps photovoltaic pumping and ground pumping photovoltaic pumping (suction stroke, different installation methods); PV pumping system: no fuel consumption, no power grid, almost no need for operation and maintenance, long service life, low average cost, especially for water and electricity shortage areas. Do not need batteries, solar modules directly driven by the pump work.
