Abstract
The utility model discloses an oil-gas multiphase pump. A three-way flange is arranged at the middle part of a pump body and is arranged near the right end of a stator; an annular groove, which is concentric with the three-way flange, is formed inside the three-way flange; orifices, which penetrate the wall of the annular groove and the inner wall of the three-way flange, are evenly formed along the inner periphery of the three-way flange; and the annular groove is communicated with an external pipeline through a pipe joint. According to the structure, by virtue of the three-way flange and especially the orifices, oil can be jet from the orifices after being filled into the annular groove when oil gas with a high gas-liquid ratio is conveyed; and oil mist jet from the orifices lubricate the conveyed gas, and thus, the gas is not in dry friction or dry burning when entering the stator and a rotor; the oil-gas multiphase pump has a lubricating effect, and thus the service life of the delivery pump is prolonged while the delivery efficiency is improved.
Description
Technical field
The utility model belongs to the transfer pump technical field, particularly a kind of oil-gas mixed delivery pump.
Background technique
In the course of conveying of oil gas, especially when high gas ratio was carried, transfer pump usually was in dry condition, can reduce the working life of transfer pump so greatly, and transfer efficiency is also had a greatly reduced quality simultaneously; More seriously under the dry friction situation, the temperature in the pump housing raises very fast, and stator is elastomer stator, thereby thereby elastomer stator dry combustion method can occur and can't use.Therefore, design a kind of can being lubricated transfer pump, improve its working life, the equipment that satisfies the efficient conveying of oil gas under the various operating modes simultaneously necessitates.
The model utility content
For solving above technical problem, the purpose of this utility model is to provide a kind of novelty simple in structure, the oil-gas mixed delivery pump that can carry the oil gas of high gas ratio.
The technical solution of the utility model is as follows: a kind of oil-gas mixed delivery pump, comprise the pump housing, stator, rotor, universal joint and drive shaft, the stator and the rotor that match are housed in its middle pump body, be connected through described universal joint between described rotor and the transmission shaft, the described pump housing of described universal joint position is provided with material feeding mouth, its main points are: at the described pump housing middle part threeway flange is housed, this threeway flange is near the right-hand member of described stator, in described threeway flange, be provided with the circular groove concentric with this threeway flange, and circumferentially evenly have the spray orifice that runs through described circular groove cell wall and this threeway flange inner wall in the described threeway flange, described circular groove is communicated with exterior line by pipe joint.Adopt above structure, owing to be provided with the threeway flange, especially be provided with spray orifice, when carry be high gas-liquid ratio oil gas the time, charge into oil at circular groove, so oil can spray from spray orifice, the mist of oil of spray orifice ejection atomizes to the medium of carrying, especially gas medium is carried out moistening, thereby be not dry friction and dry combustion method when making medium enter stator and rotor, has lubricated effect, the working life of when improving transfer efficiency, having improved transfer pump.
The described pump housing comprises the anterior pump housing and the rear portion pump housing, and butt joint has described threeway flange between this front portion pump housing and the rear portion pump housing.Adopt above structure, be convenient to the installation of threeway flange in the utility model, also be convenient to dismounting of the present utility model simultaneously.
Be connected with external pipe for convenience, be connected with the outlet counter flange at described anterior pump housing front end.
Described spray orifice is inclined hole, and this spray orifice the inner tilts to described threeway flange front-end face, and the outer end tilts to the front-end face of described threeway flange near described stator.Adopt above structure, the mist of oil of spray orifice ejection can directly be lubricated the stator in the pump and rotor, and simultaneously, a plurality of spray orifices spray simultaneously on the threeway flange, thereby make lubrication effect better.
Described spray orifice is made of big footpath hole portion, round platform hole portion and path hole portion from outside to inside successively, and the inner of wherein said path hole portion is near the right side of described stator.Adopt above structure, because the descending continuous contraction in aperture of spray orifice, the fluid flow velocity under small differential pressure action in the spray orifice will increase rapidly, and fluid forms atomized spray.
The beneficial effects of the utility model are: the utility model is simple in structure, by good design, its use has following several advantage at least: 1, be provided with spray orifice, when carry be high gas-liquid ratio oil gas the time, charge into oil at circular groove, so oil can spray from spray orifice, the mist of oil of spray orifice ejection carries out moistening to the gas of carrying, thereby not dry friction or dry combustion method when making gas enter stator and rotor, has lubricated effect, the working life of having improved transfer pump when improving transfer efficiency is so can carry the oil gas of high gas ratio; 2, owing to import and export and all to be provided with flange, so easy to connect with extraneous pipeline is easy to install.
