Definitions

At least one protective jacket provided with a barrier gas supply line can also be provided with a barrier gas discharge line provided in particular in the lower region of the protective jacket, in particular several such protective jackets connected in series, so that targeted removal of the barrier gas is possible and measured values of the specified barrier gas can be detected for evaluation are.
At least one detection device and in particular also an evaluation device can be provided for the purge gas volume flow flowing through the purge gas supply line for at least one protective jacket so that an evaluation of a wide variety of data, in particular of temperature and volumetric flow, is possible and thus conclusions about the state and the operating state of the submersible pump are possible.
sealing gas in particular provided with a Sperrgasab2020 Koch, gas barrier may be provided to keep the flammable atmosphere of the storage and sealing unit away.
a detection device and in particular also an evaluation device can be provided for the barrier gas volume flow respectively flowing through the barrier gas supply line and / or through the blocking gas discharge line for the support tube or the gas barrier, so that an evaluation of various data, in particular of temperature and volume flow, is possible and thus Conclusions on the condition and operating condition of the submersible pump are possible.
a common evaluation device for the data of at least two different detection devices can be designed for a simplified technical design including a component reduction.
a cooling device in particular in the form of liquid cooling, can be provided, so that active cooling can take place, which also allows use in hot and very hot media whose temperature may even exceed the permissible level Operating temperature of the insulated by the protective jacket components.
the protective jacket 6 is on the upper side gas-tight and the underside almost completely gas-tight with a narrow opening 9 at its lowest point formed.
the protective jacket 6 is provided in each case for one provided with a provided in the lower region of the respective protective sheath 6 Sperrgasabtechnologietechnisch 12, the Sperrgasabdiestechnisch 12 of the upper protective sheath 6, the SperrgaszuSciencetechnisch 10 of the lower protective sheath 6 forms.
