Abstract
A polished rod centralizer for replacing a sealing ring of a pumping well relates to a mechanical pumping well head matching tool. The device is characterized by comprising a cross rod and a vertical rod through a pin shaft, wherein a fixing clamping tile is fixed at the right end of the cross rod, a nut is fixedly installed at the upper end of the vertical rod, a screw rod is installed in the nut, a thrust head is installed at the right end of the nut, and a pressurizing rod is installed in the middle of the vertical rod through a pin. The polished rod centralizer with the sealing ring for the pumping well can be used for righting the polished rod to the center of a wellhead sealing box easily through the screw rod, so that the sealing ring can be replaced easily, labor and time are saved, manpower is saved, safe production can be realized, and the sealing ring cannot be crushed. The centralizer is suitable for the operation of a mechanical oil production wellhead.
Description
Technical field
The utility model relates to a kind of mechanical pumpingh well well head kit.
Technical background
In the oilfield machinery recover petroleum, using maximum is beam pumping unit.When this oil pumper is installed, it is aligned at arcuate surface and the well head center on " horse head " foremost, otherwise the oil well polished rod will be partial to a certain side of well head, and the phenomenon of polished rod eccentric wear well head seal box will take place when the unlatching oil pumper.Because oil pumper itself can't adjust this deviation,, if in certain scope, still can allow work in case this deviation has taken place.But in this case, be very easy to the well head ring wear must in time be changed, otherwise the phenomenon of meeting well head leakage of oil.In real work, most of oil well all has this deviation, not only need often to change sealing ring, bring very big difficulty also for the replacing sealing ring, since there is not proper implements to utilize, necessary two people's cooperatings, and a people will stand in and firmly spur polished rod on the well head, make polished rod be in seal box central authorities in a flash, another people compresses into seal box with screwdriver with sealing ring simultaneously.This method wastes time and energy, and is also very dangerous, and can damage sealing ring by pressure, causes damage.
The utility model content
The purpose of this utility model is to change the polished rod centralizer of sealing ring in order to design a kind of pumpingh well, utilizes it can make sucker rod be in the center of seal box at an easy rate, is easy to just replaceable sealing ring, can not cause danger, and accomplishes safety in production.
Technical solution of the present utility model is to realize like this, a kind of pumpingh well is changed the polished rod centralizer of sealing ring, its special character is, (1) is bound up by bearing pin by cross bar and montant and constitutes, the right-hand member of cross bar is fixed with the stationary slip sheet, and the stationary slip sheet connects with the active card tile mutually by pin.(2) upper end of montant is installed with nut, and screw rod is housed in the nut, and the screw rod left end is equipped with handwheel, and right-hand member is equipped with bearing collar.(3) by pin pressure rod is installed at the middle part of montant.
The beneficial effects of the utility model are, use this pumpingh well to change sealing ring polished rod centralizer, can at an easy rate polished rod be set upright the center of well head seal box by screw rod, thereby can change sealing ring at an easy rate, saving of work and time, save manpower, and can accomplish safety in production, can not damage sealing ring by pressure.
Description of drawings
Accompanying drawing 1 is a part section structural representation of the present utility model.
Accompanying drawing 2 is A-A place cross-sectional view.
Specific embodiments
The intercepting channel-section steel is made cross bar 10 and montant 7, about 150 millimeters of the length of cross bar 10, about 400 millimeters of the length of montant 7, by bearing pin 8,9 they are bound up, bearing pin 8 is steady pins, and montant 7 can be around bearing pin 8 rotations, and bearing pin 9 is removable pins, can take out (perhaps bearing pin 9 is steady pins, and bearing pin 8 is removable pins) from bar anyhow.Semicircular stationary slip sheet 11 and active card tile 12 are linked together by pin, and the other end of slips sheet connects mutually by screw, and stationary slip sheet 11 is welded on the right-hand member of cross bar 10.The fixing welded nut 2 in the upper end of montant 7 is installed in screw rod 3 in the nut 2, and the left end of screw rod 3 is equipped with handwheel 1.On bearing collar 4, have groove, bearing collar 4 is installed in the right-hand member of screw rod 3 by groove.Two identical pressure rods 5 are installed in the both sides of montant 7 respectively by pin 6, and pressure rod 5 can rotate around pin, and fixed connection in addition in the middle of two pressure rods has projection at the middle part of pressure rod 5.During use, by stationary slip sheet 11 and active card tile 12 this centralizer is fixedly mounted on the well head seal box, make the direction of screw rod 3 corresponding with the polished rod offset direction, promote bearing collar 4 by handwheel 1 rotary screw 3, polished rod can be shifted like a cork onto the center of seal box, at this time just can be easy to change the sealing ring in the seal box, after filling it up with sealing ring, available pressure rod 5 compresses sealing ring, and then the screwing hermetic lid.Use this centralizer, very convenient even the one-man also can change the well head sealing ring, saving of work and time neither can damage sealing ring by pressure, can not have an accident again, can guarantee to accomplish safety in production.
