Description
Technical Field
The invention relates to an oil-gas mixed transportation pump, in particular to a spiral axial-flow oil-gas mixed transportation pump with double shafts and bidirectional transmission.
Background
At present, in current oil-gas mixed transportation pump, all constitute a pressure boost unit by an impeller and a stator, whole pump body is internal to be constituted by a plurality of increase units, consequently at the during operation, it is all that the impeller rotates the doing work, and the stator is then motionless, play the effect of drainage, make the fluid get into next grade impeller with the minimum state of water conservancy loss, consequently, the axial distance of whole oil-gas mixed transportation pump is just very long, when needs increase the power of mixed transportation pump, just need increase the quantity of pressure boost unit, this axial that will make the mixed transportation pump is longer, thereby lead to axial vibration and noise all big, defects such as operation unstability.
Disclosure of Invention
The technical task of the invention is to provide a spiral axial flow type oil-gas mixture transfer pump with double shafts and double directions for transmission aiming at the defects of the prior art.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a two-axis two-way driven screw axial flow formula oil-gas mixture transport pump, includes the pump body to and impeller and connecting axle in the pump body, wherein the connecting axle passes through the bearing and is connected with the impeller, the front end and the pump body fixed connection of connecting axle, the terminal cover of connecting axle is equipped with the pivot, the end-to-end connection of pivot has the motor, the front end and the impeller of pivot are connected, the impeller includes forward impeller and reverse impeller, forward impeller and reverse impeller set up in turn, and the blade on the back impeller imports and designs the blade export condition on the former impeller forward bevel gear's both ends are equipped with forward bevel gear, be equipped with reverse bevel gear at reverse impeller's both ends, be equipped with drive bevel gear between adjacent forward bevel gear and the reverse bevel gear, drive bevel gear passes through the bracing piece and is connected with.
Further improvement: and the forward bevel gear and the reverse bevel gear are both connected with the connecting shaft through bearings.
Further improvement: the support rod is connected with the transmission bevel gear through a bearing.
Further improvement: the forward bevel gear and the reverse bevel gear are of the same type.
The invention has the advantages that: the original guide vane is replaced by a reverse impeller, the original impeller is a forward impeller, a pressurizing unit is composed of the forward impeller and a reverse impeller, and then the forward impeller and the reverse impeller rotate in opposite directions through the transmission of a bevel gear to form a contra-rotating impeller group, so that when the mixed transportation pump works, the impellers in the forward direction and the reverse direction do work simultaneously, and secondary work is realized, therefore, the power of the traditional pressurizing unit is equivalent to that of the traditional two pressurizing units, under the same axial length of the unit, the power of the mixed transportation pump is twice as much as the original power, or under the condition of ensuring the same pump output efficiency, the axial length of the unit is greatly shortened, the axial force is reduced, the sealing requirement is reduced, the axial vibration is reduced, the noise is reduced, and the mixed transportation pump is safer and more reliable compared with the traditional mixed transportation pump, well guarantee pump assembly steady operation, what the disrotatory impeller assembly can design in addition is than traditional impeller than the rotational speed height for oil-gas mixture transport pump efficiency obtains improving.
