The Benefits Of Robust Pump Technology | Engineer Live

To avoid endangering personnel and the environment during this process, the pump systems being used must be robust and leak-free. An intelligent material selection for avoiding sulphur-induced stress cracking or stress corrosion is just as important as having a pump with a low net positive suction head required (NPSHR).

RF-300 SEPARATING SERIES SF6 RECOVERY & PURIFIION DEVICE. RF-300 Separating Series SF6 Recovery Device allows the preparation of used SF6 gas containing an inadmissibly high percentage of nitrogen or air to the desired quality so that the SF6 can be reused in gas compartments.The purity degree of the prepared SF6 gas corresponds to the IEC

-《》

Using nitrogen(N2) or dry air to replace SF6 as insulation media in high voltage apparatus is a hot topic in the development of environmental friendly switching equipment. To ensure compact structure and small size of the devices, engineers need to study the insulation characteristics of the utilized gas and the solid-gas compound insulation.
