Abstract

The invention provides an entrance guiding cone used for a vertical oil-gas mixing transmission pump, the guiding cone is arranged at the center of the cavity of the vertical oil-gas mixing transmission pump uniform blender and positioned at the entrance of the mixing transmission pump; the guiding cone is at least constructed by a guiding cone body, a round diversion pad and a guiding cone base tightly connected with each other in sequence from top to bottom; the lateral periphery of the guiding cone is distributed with diversion vanes used for diverging the direction of the multi-phase fluid; the lateral periphery of the guiding cone base and the diversion pad are consecutive streamline surface; and the lower part of the guiding cone base is connected with the shell of the mixing transmission pump uniform blender. The guiding cone uses the diversion vanes to commutate oil-gas multi-phase fluid to be fit for entering the mixing transmission pump pressurizing unit to guarantee the normal work of the pressurizing unit, thus ensuring that the oil-gas mixing transmission pump operates stably and safely, and the work performance of the vertical oil-gas mixing transmission pump can be optimal.

Description

technical field

[0001] The invention relates to a diversion cone, in particular to an inlet diversion cone used for rectifying and dredging oil-gas multiphase fluid at the inlet of a vertical oil-gas mixed transport pump. Background technique

[0002] In fluid machinery, especially in pump machinery, the diversion cone is an important flow-passing component. Its main function is to rectify the inlet fluid, eliminate unstable states, improve flow performance, and make it conform to The machine inlet flows regularly and guides the fluid into the impeller of the pump machine. However, because the previous diversion cones can meet the requirements of ordinary water pumps under normal working conditions, the development of diversion cones has not attracted enough attention in recent years.

[0003] Since the birth of the vane oil-gas mixed pump, its performance has always been a key issue that researchers have paid close attention to. And its inlet flow state is one of the key ...
