Description
Technical field
The utility model is an oil field machinery oil pumpingh well wellhead equipment, is a kind of Castor Oil pumpingh well polished rod sealer.
Background technology
In the pumpingh well oil pumping, oil pumper drive polished rod, sucker rod, oil well pump pump and realize oil pumping, because oil pumping system is airtight, the crude oil of extraction has certain pressure; So polished rod will pump in polished rod sealer, polished rod sealer tightly embrace polished rod, the dry grinding between polished rod and the polished rod sealer appears easily, particularly when oil well is not fuel-displaced; Oil pumper remains in operation, the especially severe of dry grinding between polished rod and the polished rod sealer, and temperature raises; Cause the seal of polished rod sealer to damage, cause the oil well leakage of oil, contaminated environment; Loss crude oil also can cause the polished rod deformed damaged, and economic loss is huge.
Summary of the invention
The purpose of the utility model is a kind of Castor Oil pumpingh well polished rod sealer of design; Make pumpingh well in process of production polished rod lubricated, the dry grinding between polished rod and the polished rod sealer can not appear, the protection polished rod sealer seal and polished rod; Guarantee the pumpingh well ordinary production, avoid economic loss.
The purpose of the utility model is achieved in that and comprises and regulate cap, top cap, seal, UNICOM's cover, fuel filler neck, seal box that top cap, seal, UNICOM's cover are put and be contained in the seal box, and UNICOM's cover all has seal up and down; Regulating the cap internal thread is connected with the external screw thread on seal box top; Regulate the cap inner face and push down the upper surface of top cap, seal is pushed down in cap lower surface, top, and UNICOM has put radially duct; Fuel filler neck is installed on the seal box, and the radially duct that UNICOM puts communicates with fuel filler neck.
The beneficial effect of the utility model is: the radially duct that UNICOM puts communicates with fuel filler neck; Can polished rod be lubricated through the fuel filler neck lubrication oil of in seal box, annotating, the dry grinding between polished rod and the polished rod sealer can not occur; The seal of polished rod sealer and polished rod can not damage; Oil well can leakage of oil, does not pollute the environment, and guarantees the pumpingh well ordinary production.
Description of drawings
Fig. 1 is the assembling drawing of the utility model embodiment.
The specific embodiment
Embodiment describes below in conjunction with Fig. 1 the utility model.
Can be known that by figure the embodiment of utility model comprises adjusting cap 1, top cap 2, seal 3, UNICOM's cover 4, fuel filler neck 5, seal box 6, top cap 2, seal 3, UNICOM's cover 4 are put and are contained in the seal box 6; UNICOM's cover 4 all has seal 3 up and down, regulates cap 1 internal thread and is connected with the external screw thread on seal box 6 tops, regulates the upper surface that cap 1 inner face is pushed down top cap 2; Seal 3 is pushed down in cap 2 lower surfaces in top, and rotation adjusting cap 1 can make top cap 2 compressing sealing element 3, on UNICOM's cover 4 radially duct is arranged; Fuel filler neck 5 is installed on the seal box 6, and the radially duct on UNICOM's cover 4 communicates with fuel filler neck 5, to fuel filler neck 5 oilings; Can make and inject in the oil entering seal box 6, the polished rod lubricate.
