Abstract
The utility model relates to a speed-increased oil submersible electric pump, which comprises a centrifugal pump, an oil-gas separator, a protector, a speed increaser and an oil submersible motor which are connected in series by a flange. The utility model also comprises an upper seat body of the speed increaser, a lower seat body of the speed increaser, a shell which is connected between the two seat bodies by screw threads and a gear speeder which is arranged in the shell. The speed increaser is connected between an upper protector and a lower protector of the oil submersible electric pump in series by a flange bolt and forms cylinder-shaped. The practice can prove that the speed-increased oil submersible electric pump can increase speed above 1.4 times. The wax and sand portable capacity of crude oil can be enhanced, a pump inspection cycle can be reduced, the production time rate of an oil well can be increased, and the utility model is welcomed by production units.
Description
The utility model belongs to a kind of speedup submersible electric pump used in the oil field machinery oil.
The oil field generally enters the middle and later periods exploitation at present, the oil-immersed pump oil recovery is recovered the oil than other modes and is had remarkable advantages, its major advantage is that discharge opeing is even, oil flow velocity degree is higher, thereby taking sand, to take the wax ability stronger, big at lifting rate, watered-out well, high-yield well especially use on the directional well and have received obvious effects.But because rotating speed is slower, have only 2850r/min, lift is lower, the well big to some sand content, not ideal enough to the oil well of fouling and mineralization, pump detection period is short, make troubles to production management, carry the oil-immersed pump rotating speed just becomes scientific and technical personnel's main direction in the world for this reason.
The purpose of this utility model is exactly for overcoming the existing slow shortcoming of submersible electric pump rotating speed, having designed a kind of speedup submersible electric pump.
The technical solution of the utility model is achieved in that
The utility model comprises centrifugal pump, deaerator, protector, speed increaser and the oil-submersible motor that is connected in series by flange, the upper pedestal of speed increaser and lower base, and between two pedestals by the housing that is threaded and be assemblied in gear speeder in the housing, it is serially connected between the last protector and following protector of submersible electric pump, be tubular, connect by flange, bolt; The input shaft lower end of gear speeder is connected with the axle of following protector by rectangular spline, the upper end is connected by the concave-convex shape gear engagement with the gear shaft lower end, the upper end of gear shaft is connected by rectangular spline with the spill gear, the spill gear is connected with the convex gear engagement of output shaft lower end, the upper end of output shaft spool is connected by rectangular spline and last protector, with sphere or pearl oblique crank Z hold and eccentric bushing spacing between upper pedestal and lower base; Gear speeder is made as the two-stage speed change, and gear engagement is the convex-concave engagement; The input shaft upper end is one with the spill gear, and gear shaft lower end and convex gear are one, and output shaft lower end and convex gear are one; Output shaft lower end and convex gear are one; Between two groups of speed change gears, be provided with eccentric bushing; adjust concentricity therebetween; stud with ball bearing or the pearl oblique crank Z holds in input shaft, gear shaft and output shaft side direction; internal diameter communicates between upper pedestal and last protector; on upper pedestal and lower base, be provided with protective cap, guarantee that the not impaired and inner gear oil that is full of does not leak in its transportation process.
The utility model has enlarged the accommodation of existing submersible electric pump, improves discharge capacity more than 0.45 times.Under identical lift condition with existing submersible electric pump, the progression of pump can reduce over half, has reduced the total length of unit, has saved the manufacture cost of electric pump.The rotating speed of submersible electric pump improves, and has strengthened taking the wax prop-carrying capacity, having reduced pump detection period of crude oil, and rate during the production that improved oil well is made a pet of by production unit deeply.
For the technical solution of the utility model is further open, elaborate below in conjunction with Figure of description:
