Description
Technical field:
The utility model relates to the high gassiness underground water in a kind of oil field submersible pump downhole gas water separation device that submersible pump uses that draws water.
Background technique:
Oil field underground water or geothermal well intake equipment are mainly used submersible pump at present, this pump is made up of motor and multistage centrifugal pump, submersible pump is in pump process: when air content in the well water is big, gas is in water enters pump, when high speed rotating, gas is separated out from water, because of the density of gas produces less centrifugal force than density of liquid is little.Thereby the pressure reduction at liquid level and Pump Suction Nozzle place is not enough to liquid in the well is pressed into and is lifted to ground in the pump in the well, and this kind phenomenon is called " air sinuses phenomenon ".The geothermal resources comprehensive utilization is carried out in the Liaohe Oil Field at present; geothermal well is distributed near the oilfield district more; air content is very big in indivedual well water; use existing submersible pump to draw water normal appearance " air sinuses phenomenon " and the phenomenon that causes occurring intermittently stopping; as shut down and handle untimelyly, will cause the accident of burn-down of electric motor to take place.
The model utility content:
The purpose of this utility model provides a kind of submersible pump downhole gas water separation device; this device solves exist in the prior art and utilize submersible pump to draw water in the big well of air content to be prone to " air sinuses phenomenon " and cause submersible pump intermittently cutout to occur, shut down the problem that untimely meeting causes burn-down of electric motor of handling.
The technological scheme that its technical problem that solves the utility model adopts is:
Submersible pump downhole gas water separation device is by motor for submerged pump, pipe nipple flange, separator pipe nipple, separator body: suction hole, double-deck blower inlet casing, water guide exhaust port, water guide umbrella, the submersible pump pump housing, lifting pipe are formed: motor for submerged pump is connected with the pipe nipple flange with the separator pipe nipple, separator pipe nipple and the screwed connection of separator body; Cylindrical shape separator body adopts double-deck blower inlet casing, be provided with 35～40 suction holes of diameter 20mm in corresponding submersible pump water sucking mouth, blower inlet casing bottom seal welding, open top, A is a water (flow) direction, be provided with the water guide umbrella of two-layer 45 ° of lead angles in the annular space, being provided with staggered 20～30 diameter 20mm suction hole in the water guide umbrella of upper strata is the water guide exhaust port, is provided with the suction hole (exhaust port) of staggered 110～120 diameter 10mm in lower floor's water guide umbrella; Separate body and be located at submersible pump pump housing outside, the submersible pump pump housing is connected with flange with lifting pipe.During this device work: by a kind of gas and water separator being installed at motor and submersible pump water sucking mouth; make well water can not directly enter the submersible pump water sucking mouth; but it is catheter directed by separator; change pump water sucking mouth water (flow) direction; by the airborne low flow velocity of separator water guiding ring; utilize the gravity drop that gas is separated from water, " air sinuses phenomenon " occur and cause intermittently cutout, shut down the untimely motor problem of burning that causes thereby solve submersible pump.
The beneficial effects of the utility model are:
This apparatus structure is simple, be convenient to operation, owing to set up gas and water separator and draw water in high gassiness hot well, effectively solved " air sinuses phenomenon " and causes intermittently cutout to shut down the untimely motor problem of burning in the submersible pump, reduces maintenance expenses.
