The braking device can realize complete discharge of the polish rod at short notice to achieve the purpose of stable closed-down.
Description
Technical field:
The utility model relates to the used braking device of oil recovery field, oil field screw pump, especially hydraulic type oil pumping screw pump reverse rotation speed limit braking device.
Background technique:
In the oil recovery process of oil field, mechanical oil recovery is still the main method of current oil recovery, and screw pump is a kind of new mechanical oil production equipment, is fit to exploitation high viscosity, gassiness, contains husky crude oil; Screw pump mainly drives rotor by drive unit by sucker rod and rotates in stator, and down-hole crude oil is pumped to the purpose that ground reaches oil pumping.And existing screw pump is very big owing to the elasticity of load, the danger with very big harm out of control of the resilience during shutdown.On the one hand existing screw pump brake setting is on motor termination or output shaft; when breaking down on motor termination or the output shaft and between the polished rod; cause brake failure; owing to adopt the rigidity braking, the polished rod moment of torsion that elastic load causes still exists, and does not reach steady shutdown on the other hand; especially can not guarantee the requirement of polished rod complete discharge; discharge still very dangerously, even cause screw pump to damage even jeopardize personal safety, bring hidden danger.
The model utility content:
Shut down the deficiency that the out of control and rigidity braking reaction torque of polished rod counter-rotating can not the safety and steady unloading in order to overcome existing screw pump; the utility model provides a kind of hydraulic type oil pumping screw pump reverse rotation speed limit braking device; this hydraulic type oil pumping screw pump reverse rotation speed limit braking device can reach polished rod complete discharge at short notice, reaches the purpose of steady shutdown.
The technical solution of the utility model is: this hydraulic type oil pumping screw pump reverse rotation speed limit braking device comprises the clamp holder that is fixed on the polished rod, connecting sleeve and the outer end cap that is nested, middle land and outer shroud that the end cap upper joint sleeve is covered with upper surface band connected in star outward successively are the free wheel device of cam outward, clutch has respectively up and down and clamp holder and the connecting sleeve stage of cutting ferrule mutually, clutch is covered mutually by housing, housing links to each other with middle land and end cap, the housing skirt wall is built-in with the radial plunger pump of several no oil outlets, the plunger of pump touches mutually with cam, and the import of pump communicates with groove.
Above-mentioned pump is built-in with steel ball for vertical hole, is with spring and plunger successively on the slide bar in the cross-drilled hole that intersects with vertical hole; Be fixed with sliding sleeve by jackscrew between housing upper end and middle land lower end and clutch upper and lower end; The fin that has the annular groove with the clutch lower surface to match on the middle land.
The beneficial effect that the utlity model has is: this hydraulic type oil pumping screw pump reverse rotation speed limit braking device is owing to being the free wheel device of cam outside middle land that is covered with upper surface band connected in star outside the end cap upper joint sleeve successively and the outer shroud, clutch is covered mutually by housing, radially is equipped with the plunger pump that several touch mutually with cam in the housing skirt wall.Break directly acts on sucker rod polished rod place like this; improved reliability; by plunger pump the counter-rotating rotating speed that moment produces is controlled in the safe scope; guarantee polished rod complete discharge at short notice simultaneously; so this hydraulic type oil pumping screw pump reverse rotation speed limit braking device can reach polished rod complete discharge at short notice; reach the purpose of steady shutdown, and simple in structure.
Description of drawings:
Accompanying drawing 1 is the utility model structure sectional view;
Accompanying drawing 2 is to remove the A of end cap and middle land among Fig. 1 to view.
1-connecting sleeve among the figure, 2-end cap, land in the middle of the 3-groove, 4-, 5-free wheel device, 6-cam, the 7-housing, 8-clamp holder, 9-spring, 10-fin, 11-stage, 11-plunger, the 13-sliding sleeve, the 14-steel ball, the 15-radial plunger pump, 16-indulges the hole, 17-cross-drilled hole, 18-slide bar.
Embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail:
By Fig. 1 in conjunction with shown in Figure 2, this hydraulic type oil pumping screw pump reverse rotation speed limit braking device comprises the clamp holder 8 that is fixed on the polished rod, connecting sleeve 1 and the outer end cap 2 that is nested, the end cap 2 upper joint sleeves 1 outer middle land 4 that is covered with upper surface band connected in star 3, the middle land 4 upper joint sleeves 1 outer outer shroud that is covered with is the free wheel device 5 of cam 6 outward, the fin 10 that middle land 4 upper surfaces have the annular groove with clutch 5 lower surfaces to match, have on the clutch 5 and clamp holder 8 stage 11 of cutting ferrule mutually, clutch has for 5 times and connecting sleeve 1 stage 11 of cutting ferrule mutually, clutch 5 is covered mutually by housing 7, housing 7 upper ends and middle land 4 lower ends be fixed with sliding sleeve 13 between clutch 5 upper and lower end are corresponding; Housing 7 links to each other with middle land 4 and end cap 2, be equipped with steel ball 14 under in interior 12 the vertical holes 16 of housing 7 skirt wall, be built-in with slide bar 18 at the cross-drilled hole 17 that intersects with vertical hole 16, the sliding spool 12 that is with spring 9 on the slide bar 18 successively and touches mutually with cam 6, the import of vertical 16 lower ends, hole communicates with groove 3, in the groove 3 machine oil is housed, forms radial plunger pump 15.
During actual the use; when screw pump is shut down; the counter-rotating that moment produces drives free wheel device 5 counterrotatings by polished rod by clamp holder 8; free wheel device 5 cams 6 outer shrouds extruding plunger 12 slides in housing 7; outside housing 7, sliding under the effect of spring 9 then; at this moment steel ball 14 upwards floats; groove 3 communicates with the import of 16 lower ends, vertical hole, and groove 3 inner engine oils suck, and forms radial plunger pump 15; because this not outlet of pump 15; so just produce entrap phenomenon, thereby plunger 12 passes through the rotating speed of free wheel device 5 restriction polished rods, so just the counter-rotating rotating speed that moment is produced is controlled in the safe scope; guarantee polished rod complete discharge at short notice; reach the purpose of steady shutdown, because of break directly acts on sucker rod polished rod place, improved reliability again; eliminated potential safety hazard; and the brake portion split is independent, can be supporting with various ground installations in usefulness, also can be integrated in the follow-up ground installation; realize integrated, easy control that braking force is adjustable.
