Description
Technical field
The utility model relates to oil-immersed pump, is specifically related to a kind of oil-immersed pump separator scale removal mechanism.
Background technique
The Main Function of oil-immersed pump separator in submersible electric pump is that the liquid gas in well liquid is separated, liquid enters the pump housing, gas is discharged to sleeve pipe toric space, prevent gas lock and vapour lock, oil-immersed pump separator is made up of upper lower contact, housing, lining, rotor, the induction of being fixed on transmission shaft is separated wheel and is referred to as rotor, and induction separator is the critical piece that the liquid gas in oil-immersed pump separator is separated.
Existing oil-immersed pump separator can realize liquid, gas separation, sand control, corrosion-resistant function, good handling is not also had to antiscale, the work influence of dirt in well liquid to oil-immersed pump is maximum, especially after blade guiding wheel produces fouling, add the friction factor of impeller and guide wheel, greatly reduce the working efficiency of oil-immersed pump, cause the situation of unit braking and motor damage.
Facts have proved, existing oil-immersed pump separator is inadaptable to special hole condition, must increase its function, effectively prevents fouling to the damage of oil-immersed pump.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of effective scale removal to extend the oil-immersed pump separator scale removal mechanism in oil-immersed pump working life.
For achieving the above object, the utility model provides following technological scheme: a kind of oil-immersed pump separator scale removal mechanism, comprise tubular shell, rotatingshaft, filter body and sheathed on the rotating shaft protect central siphon, protecting central siphon is inserted in tubular shell, described filter body is gap-forming filtering cavity between tubular shell, described filter body is inserted in filtering cavity, be sealed and matched between described filter body one end and the described outer wall protecting central siphon, the outer wall sealing paste of the described filter body the other end is located on the inwall of described housing, filtering cavity is separated into fluid entering channel and fluid outlet passage through filter body, described fluid entering channel and fluid outlet passage filtering hole on filter body is communicated with.
By adopting technique scheme, after well liquid enters oil-immersed pump separator, sheathed protecting central siphon and can completely cut off the direct contact of well liquid to rotatingshaft on the rotating shaft, serve the effect of sand control, filter body and protect central siphon and form a filter cavity, make well liquid after filtration core body filter after scale removal and flow to gas-liquid separation device, realize effective scale removal, the formation having lacked fouling makes oil-immersed pump greatly extend working life.
The utility model is set to further: the side face of described filter body is provided with several water passage holes, and described water passage hole circumferential arrangement axial distribution are on the side face of described filter body.
By adopting technique scheme, make the well liquid after filtering from the high efficiency outflow of water passage hole, the working efficiency of oil-immersed pump can be increased.
The utility model is set to further: described housing two ends are connected with connecting head, the end face seal protecting central siphon and filter body in described connecting head described in correspondence is fitted a sealed pipe, the outer wall of described sealed pipe and connecting head inwall form passage, and the other end of described sealed pipe connects a connecting bushing.
By adopting technique scheme, play effect convenient for assembly, effective well liquid that must prevent that arranges of sealed pipe penetrates on rotatingshaft, formed passage make filter after well liquid can high efficiency stream to gas-liquid separation device, connecting bushing makes the axle in rotatingshaft and gas-liquid separation device link into an integrated entity, and realizes synchronous axial system.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
