Promptly change the well head eccentric abrasion prevention load reducer of beam hanger airtight and watertight padding.
Of the present utility model technology is characterized in that well head eccentric abrasion prevention load reducer, by oil-containing groove (1), pressure cap (2), boosting-rod
(3), steering ball end (4), ball cup (5), gate (6), off-load packing (7), leading screw (8), a word handle (9), oil pumping polish rod set
The mouth of pipe (10), grid (11) and oil pumping polish rod (12) composition, it is characterised in that described pressure cap (2) in inverted " u "-shaped, centre position
It is provided with an oil pumping polish rod sleeve opening (10)；It is arranged with a pair boosting-rod (3) on the outer wall of pressure cap (2), is provided with bottom inverted " u "-shaped
Oil-containing groove (1)；Wherein said off-load packing (7) is " T " shape, and one end connects with leading screw (8)；Described on gate (6) one
The endoporus of word handle (9) is provided with the female thread being meshed with leading screw (8) external screw thread；Described oil pumping polish rod (12) outer wall is coated with tungsten
Alloy or evanohm.
Described ball cup (5) is polytetrafluoro nylon material, indent, and centre is provided with an oil pumping polish rod sleeve opening (10).
Described off-load packing (7) is silicone rubber material, and in high netting shape, lubricant grease embeds in grid (11).
The utility model has the advantages that simple in construction, easy to adjust, safe and reliable, work efficiency high pollution is little, Ke Yi great
In the service life of big extension device, save maintenance time and the expense of equipment, there is considerable economic and social benefit, Ke Yiguang
Promote the use of on ubiquitous oil-field oil pumper.
