Two-way autorotation type oil-gas multiphase pump

Abstract

The invention discloses a two-way autorotation type oil-gas multiphase pump. The pump comprises a pump body connecting shaft and impellers, the connecting shaft is composed of a plurality of sections of rotating shafts, every two adjacent rotating shafts are connected in a rotary sleeving mode, commutators are arranged at two ends of each rotating shaft, an iron core is arranged in the middle of each rotating shaft, a plurality of sets of coils are wound around the iron core, two ends of the coils are connected with a conductor on a front commutator, the rotating shaft between the iron core and a rear commutator is connected with an inner shell through a bearing, a pair of magnets is arranged inside inner shells, the magnetic poles in the two adjacent inner shells are opposite, one ends of the rotating shafts are connected with the impellers through supporting frame, original guide vanes are replaced with the impellers, the two adjacent impellers are arranged in opposite directions, the rotation directions of the two impellers are also opposite during working, so that when the multiphase pump works, the impellers in the forward direction and the backward direction do work at the same time, and the power of the multiphase pump with the same unit axial length is twice of the original power.

Description

technical field [0001] The invention relates to an oil-gas mixed transport pump, in particular to a bidirectional self-rotating oil-gas mixed transport pump. Background technique [0002] At present, in the existing oil-gas mixed pump, a booster unit is composed of an impeller and a guide vane, and the whole pump body is composed of multiple booster units, so when working, the impeller rotates to do work, and the The guide vane is still and plays the role of drainage, so that the fluid enters the next-stage impeller with the minimum water loss. Therefore, the axial distance of the entire oil-gas mixed pump is very long. When it is necessary to increase the power of the mixed pump When this happens, it is necessary to increase the number of booster units, which will make the axial length of the mixed pump longer, resulting in large axial vibration and noise, unstable operation and other defects, and the existing oil-gas mixed pumps are An external motor is needed to drive th...
