Abstract: A method for generating a continuous carrier gas/vapour mixture stream containing a carrier gas, and a vapour of a liquid. The method includes provision of a first metered carrier gas stream, provision of a second metered carrier gas stream, provision of a metered, vapour-saturated carrier gas/vapour mixture stream, mixing of the second stream and the metered stream to provide a first gaseous mixture stream; and provision of a metered liquid stream fed to an evaporation/mixing device for evaporating the liquid and mixing with the first gaseous mixture stream to provide a second gaseous mixture stream.

Abstract: A clamping device for fixing a drive shaft of a delivery pump inside a rising pipe of a borehole for the delivery of a delivery fluid. The clamping device includes a housing with a first passage bore, through which the drive shaft of the delivery pump passes. The clamping device also includes at least a second lateral passage bore, which meets the first passage bore orthogonally, wherein a mechanically acting clamping means is accommodated and/or guided in the second passage bore, by means of which clamping means the drive shaft of the delivery pump can be fixed axially and/or radially in the housing of the clamping device. A method for the spatial fixing of a drive shaft of a delivery pump in a stationary manner in a rising pipe assigned to a borehole is also disclosed.

Abstract: A reverse rotation protection for borehole pumps is disposed in a drive head. The reverse rotation protection includes a housing and a clamping tool for securing a polished rod. The clamping tool includes at least two exchangeable contact elements with which the polished rod can be fixed releasably.
