Abstract
An affusion pump lining puller is a special tool for replacing the shaft lining in the process of oil filed stratum affusion pump maintenance. The utility model consists of a screw, a nut, a retaining ring and a draw ring; the utility model is characterized in that both ends of the screw are equipped with screw threads and one end of the screw is equipped with a retaining ring sleeve; the screw thread of the screw is equipped with the nut; and the other end of the screw thread is equipped with the draw ring; the draw ring is connected with the screw by threads. The beneficial effect of the utility model is that the utility model of a novel affusion pump lining puller is used to take out the affusion pump lining; the operation is simple and the affusion pump lining hole at the fluid end is not damaged; the utility model solves the problem that the lining is hard to be taken out in a normal way in the process of affusion pump fluid end maintenance.
Description
Technical field
The utility model relates to a kind of maintenance tool, is a kind of specific purpose tool that keeps in repair the oil field stratum water injecting pump, when being mainly used in maintenance water injecting pump replacing neck bush, takes out the specific purpose tool of lining from the pump head bush hole.
Background technology
Between the fluid end of oil field stratum water injecting pump and the piston rod lining is arranged.Because during mounting bush, adopted win to cooperate between lining and the pump head; The long-term superelevation pump pressure running of water injecting pump, lining can produce gross distortion; Long-term in addition field condition, reasons such as the pump head corrosion of lining periphery have caused adhesion between lining and the pump head.During maintenance water injecting pump dismounting lining, be difficult in bush hole, take out lining.At present, there is not reliable specific purpose tool that lining is taken out from bush hole.The method that the maintenance operation personnel adopt hammer to pound solves.This method wastes time and energy, and also bush hole might be pounded distortion, new lining is installed for replacing and is brought difficulty.
The utility model content
The purpose of this utility model is: for the maintenance water injecting pump provides a kind of specific purpose tool--the water injecting pump bushing extractor, and when making the maintenance operation personnel from water injecting pump fluid end bush hole, take out the water injecting pump lining, convenient and strength-saving.Overcome and adopt hammer to pound to get lining, the effort of taking a lot of work smashes the fluid end bush hole, gives to change and new crank guide is installed is brought difficult deficiency.
The technical solution adopted in the utility model is: the water injecting pump bushing extractor by screw rod, nut, baffle ring and lift the ring form, it is characterized in that: there is screw thread at the two ends of screw rod, baffle ring is enclosed within an end of screw rod, on the screw thread of screw rod nut is arranged; On the screw thread of the other end of screw rod, lift ring, lift ring and be connected with screw flight.
For adapting to the special construction of water injecting pump bush hole, described screw rod is shaped as step-like cylinder.
Maintenance water injecting pump fluid end in the time of need taking out the water injecting pump lining from bush hole, at first will lift ring and disassemble from screw rod; And make screw rod pass the centre bore of lining; On screw rod, screw and lift ring.Lift the external diameter little 1-3 millimeter of the external diameter of ring than lining.Baffle ring and nut band is good and screw, continue the rotation nut, baffle ring shortens with the distance that lifts ring.Lifting ring extracts lining from water injecting pump fluid end bush hole.
The beneficial effects of the utility model: use the utility model water injecting pump bushing extractor can finish the water injecting pump lining and take out, and have simple to operately, do not damage water injecting pump fluid end bush hole.When having solved maintenance water injecting pump fluid end, lining is difficult to normal problem of taking out.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model water injecting pump bushing extractor structural profile schematic diagram.
Among the figure, 1. screw rod, 2. nut, 3. baffle ring 4. lifts ring.
The specific embodiment
Embodiment 1: consult accompanying drawing 1.The screw rod 1 of the utility model water injecting pump bushing extractor is step-like cylinder, 24 millimeters of upper end diameter, 260 millimeters of length; 16 millimeters of lower end diameter, 200 millimeters of length.Screw rod 1 upper end is a trapezoidal thread.There is the nut 2 of trapezoidal thread the upper end, and baffle ring 3 is enclosed within on the screw rod 1.At the lower end of screw rod 1 screw thread is M16.Lift 32 millimeters of ring 4 external diameters, following 2 millimeters than the external diameter of lining.The thickness that lifts ring 4 is 12 millimeters.Lifting ring 4 is threaded with screw rod 1.
Claims (2)
