Description

A kind of volume increase buffer unit on oil extractor

Technical field

This utility model belongs to petroleum industry machinery technical field, particularly relates to a kind of for oil extractor Volume increase buffer unit.

Background technology

At present, domestic petroleum industrial machinery oil extractor do not has any buffer unit, on oil extractor Outstanding rope upper end be fixed on caput Equi Asini, lower end connect polished rod eye, polished rod pass polished rod eye, its upper end is by just blocking Son is fixed on polished rod eye, lower termination sucker rod, and there are the following problems for current this structure: (1) sucker rod The static load elastic deformation of post and oil pipe, causes the actual stroke of oil pump plunger piston to be always less than its theoretical stroke, The actual efficiency ratio of oil well pump is relatively low, generally can only achieve the 70～80% of its theoretical efficiency；(2) When caput Equi Asini starts up, the transfer of the instantaneous inertial load and liquid bar load that act on rod string easily causes The disconnected of rod string takes off, and meanwhile, temporary impact load causes motor current value to strengthen, and energy consumption increases.

Utility model content

This utility model provides a kind of volume increase buffer unit on oil extractor, to solve above-mentioned background Problem in technology.

For solving the problems referred to above, this utility model following technical scheme of offer: a kind of novel undisturbed soil soil sampler, Including soil sampler body, be provided with, on the downside of described soil sampler body, the base that fetches earth, described in fetch earth and be welded with on base Triangular support bracket, described triangular support bracket top is welded with the first screw mandrel holder, and described first screw mandrel is fixed Being provided with the second screw mandrel holder on the downside of device, described second screw mandrel holder is welded with connecting shaft.Described connection Axle welds with inside triangular support bracket, and described soil sampler body is provided with screw mandrel, described screw mandrel all with the first screw mandrel Holder and the second screw mandrel holder are threaded, are provided with, on the downside of described screw mandrel, the main body that fetches earth, described in fetch earth master Internal portion is provided with soil-shifting piston, and described screw mandrel upper end is provided with connection seat, and described connection seat is provided with rotary handle.

Further, described upper backup pad and lower supporting plate are connected by axostylus axostyle, and spiral shell is passed through at described axostylus axostyle two ends Female fixing.

Further, described spring body can be rubber spring or polyurethane spring.

Further, being provided with oil-in on the downside of described extracting device of oil, side, described extracting device of oil upper end is provided with out Hydraulic fluid port.

Further, described caput Equi Asini side is fixedly connected with swing arm, and described swing arm side is provided with driving dress Putting, described driving means side is provided with motor.

The beneficial effects of the utility model are: the volume increase buffering dress on oil extractor of the present utility model Put, by the first buffer spring and the second buffer spring, improve the efficiency of spring buffer, add buffering The service life of spring.And owing to spring has the characteristic of buffering, when its be installed in beam hanger for pumping machine with Time between Fang Kazi, in compression and recovery process, all add the upper and lower stroke of oil pump plunger piston, i.e. Add the yield of oil pumper.According to the actual test of industrial field, this utility model institute installed by oil pumper After the volume increase buffer unit stated, can increase yield more than 10%, for petroleum industry, this is very Considerable rate of growth；And this volume increase buffer unit is cheap, for the barreler of the daily output more than 20 tons, The interests that volume increase in a day brings just are recoverable to the Meteorological of this volume increase buffer unit；Meanwhile, it can absorb again When caput Equi Asini starts up, Ground shock waves load in the inertial load of rod string and oil pump running, reduces electric power Energy resource consumption, improves motor, rod string and box cupling and connects the force status of screw thread, reduces rod string and breaks De-rate, extends their service life.
