Description
Diaphragm-type batteries consist of seamless cylindrical pressure vessels made of high-strength steel. The interior of the battery is divided into two parts by a flexible diaphragm: the gas side and the liquid side. The membrane is filled with nitrogen up to the specified gas charge pressure (P0). When liquid enters the battery, the gas in the diaphragm is compressed, increasing the pressure and allowing the fluid to flow in. If the pressure on the liquid side falls below the gas pressure, the battery will be discharged. The oil valve closes when the pressure on the gas side is higher than the pressure on the liquid side, thus preventing the destruction of the diaphragm.
