CONFIGURATION OF A WORM GEROTOR PUMP

摘要

The invention relates to drilling engineering, in particular to gerotor eccentric worm positive-displacement pumps for pumping gas-fluid mixtures exhibiting an extended range of viscosity. The configuration of a gerotor pump comprises such units as a discharge flange (7), a worm pumping unit (1), a branch housing (5) and a spindle (8), which are positioned in series and are interconnected with the aid of fixing devices (12, 13) provided with flange units. Each fixing device comprises at least one flange unit embodied in the form of a rotatively removable structure enabling to rotate said in series positioned main units about the pump longitudinal axis at any required angle within the working range. Said invention makes it possible to reduce the cost and manpower input for producing, mounting and maintaining worm gerotor pumps,
