Prevent sucker rod and its box cupling and tube inner wall from generating eccentric wear it is necessary to sucker rod stabilizing.Existing oil pumping rod centering device
The realization for biasing toward wear-resisting functions can not achieve the effective protection to sucker rod without effectively accomplishing anti-corrosion.
Utility model content
In view of the deficiencies in the prior art and defect, the purpose of this utility model is to provide a kind of pumping rod anti-corrosives
Centralizer lacks anti-corrosion function to solve oil pumping rod centering device existing in the prior art, and the utility model structure is simple, can have
Effect is played to sucker rod stabilizing and anti-corrosion dual function.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution: a kind of anticorrosion centralizer for sucker rod,
Including supporting positive cover, convex block, idler wheel, non-corrosive metal (NCM) block, limiting groove, the number of slugs be it is multiple, the convex block is helped described in
The positive set circle spacing is set to supporting positive cover outer wall, and the limiting groove is set to interval between the convex block, the anti-corrosion gold
Belong to block to be set to inside limiting groove, the idler wheel is vertically disposed on the convex block, idler wheel a part insertion
In convex block, a part is outside convex block.The setting of convex block and idler wheel effectively plays the role of abrasionproof, and supporting positive cover can be to avoid oil pumping
Bar generates bias, and non-corrosive metal (NCM) block effectively avoids the corrosion of sucker rod.
The limiting groove is externally provided with elastic piece, and the elastic piece both ends connect the limiting groove upper and lower ends, described
Limiting groove is internally connected with spring, and the spring is along the supporting positive cover radial motion.Effectively non-corrosive metal (NCM) block can be fixed, be kept away
Exempt to be detached from limiting groove after non-corrosive metal (NCM) block is corroded, meanwhile, the setting of limiting groove facilitates the replacement of non-corrosive metal (NCM) block.
Shaft is equipped in the middle part of the idler wheel, the idler wheel and the shaft are rotatablely connected, the both ends of the shaft with it is described convex
Block is fixedly connected.Idler wheel can effectively avoid abrasion.
The non-corrosive metal (NCM) block is the strong spelter or aluminium block of activity.Spelter, the metal activity of aluminium block are strong, can be with medium
In ionic reaction avoid the corrosion of sucker rod to protect sucker rod.
Compared with prior art, the utility model has the beneficial effect that
1. the utility model structure is simple, easy for installation, it is can effectively protect sucker rod, avoids the corrosion of sucker rod.
2. the utility model can effectively prevent generation eccentric wear between sucker rod and tube inner wall to cause sucker rod serious wear
Or it is de- disconnected, effectively extend the service life of sucker rod.
3. non-corrosive metal (NCM) block uses spelter or aluminium block in the utility model, spelter, the metal activity of aluminium block are strong, in medium
Ion preferentially with non-corrosive metal (NCM) deblocking reaction, so that sucker rod be protected not to be corroded.
