Integrated two-way transmission oil-gas multiphase pump

Abstract

The invention discloses an integrated two-way transmission oil-gas multiphase pump. The pump comprises a volute and impellers, rotating shafts are arranged in the impellers, driven gears are arranged on the inner sides of the rotating shafts, grooves are formed in the inner wall of a connecting position of the impellers, a sleeve is arranged in the groove, a double-end motor is arranged in the sleeve, driving gears are arranged at two ends of the double-end motor, one driving gear is directly engaged with one driven gear, and the other driving gear is engaged with the other driven gear through a transmission gear. Firstly, a power supply can be provided for the double-end motor through a conductive contact, a conductive ring and a conductive elastic sheet, during working, the two impellers rotate in opposite directions to form a counter-rotating impeller group, so that when the multiphase pump works, the impellers in the forward direction and the backward direction act simultaneously, therefore, the power of one supercharging unit is equivalent to the power of two traditional supercharging units, and the power of the multiphase pump is twice of the original power under the same axial length of an unit, so that the efficiency of the oil-gas multiphase pump is improved.

Description

technical field [0001] The invention relates to an oil-gas mixed delivery pump, in particular to an integrated two-way transmission oil-gas mixed delivery 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 , it is necessary to increase the number of booster units, which will make the axial direction of the mixed pump longer, and in the existing oil-gas mixed pump, the motor is arranged at one end of the pump body, resulting in axial vibration And the noise is big, the operation is unstable and oth...
