Abstract

The utility model relates to a blowout prevention cleaning machine of a pumping unit. The blowout prevention cleaning machine of the pumping unit comprises a packing box, an inner pressure reducing structure of the blowout prevention cleaning machine, a downwards inclined oil outlet pipe, a circular ejector rod, a sealing sleeve box and an oil pumping steel pipe. The blowout prevention cleaning machine of the pumping unit is characterized in that the packing box is welded with the blowout prevention cleaning machine, the upper portion of the packing box is arranged inside the blowout prevention cleaning machine, and the inner pressure reducing portion of the blowout prevention cleaning machine lifts and is linked up with the inner edge of the blowout prevention cleaning machine. The blowout prevention cleaning machine of the pumping unit is simple in structure, low in cost, convenient to maintain, long in service life and beneficial for popularization.

Description

A kind of oil pumper blowout prevention cleaner

Technical field

The utility model relates to a kind of oil pumper blowout prevention cleaner.

Background technology

The packing that use in more current oil fields exists abrasion resistance and the poor problem of sealing.Oil pumper normal operation, steel pipe are pumped up and down and are produced friction with packing.Poor because of sealed packing elasticity and abrasionproof, cause very soon wearing and tearing, after the packing wearing and tearing, the leakage of oil of packing box mouth and oil spout.This causes the wasting of resources and economic loss, and contaminated environment.

Summary of the invention

The purpose of this utility model is to provide a kind of oil pumper blowout prevention cleaner, in order to prevent leakage of oil and oil spout, minimizing economic loss and environment pollution, blowout prevention cleaner of the present utility model can concentrate on the spray oil spill in the blowout prevention cleaner, hold in the oil sump by tiltedly playing steel pipe to flow to, thereby prevent that the oil after oil spout and the leakage of oil from flowing to ground.

The purpose of this utility model is achieved in that a kind of oil pumper blowout prevention cleaner, comprises following part: packing box; Blowout prevention cleaner inner pressure relief structure; Tiltedly lower flowline; Circular push rod; Sealed jacketed box; With the oil pumping steel pipe; It is characterized in that: wherein packing box and blowout prevention cleaner welding, part is inner at the blowout prevention cleaner on the packing box, and inner pressure relief partly rise with the blowout prevention cleaner in along rank mutually.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of existing packing box.

Fig. 2 is the utility model oil pumper blowout prevention cleaner master TV structure schematic diagram.

The specific embodiment

A kind of oil pumper blowout prevention cleaner as depicted in figs. 1 and 2, comprises packing box 9; Blowout prevention cleaner inner pressure relief structure 4; Tiltedly lower flowline 6; Circular push rod 7; Sealed jacketed box 8; Oil pumping steel pipe 2; Wherein packing box 9 and the welding of blowout prevention cleaner, part is inner at the blowout prevention cleaner on the packing box, and inner pressure relief partly rise with the blowout prevention cleaner in along rank mutually. [0009]Blowout prevention cleaner structure of the present utility model as shown in Figure 2, the oil after the leakage of oil of used packing box and the oil spout (as shown in Figure 21 leakage of oil and oil spout point), the spray oil spill enter in the blowout prevention cleaner.Leakage of oil pressure hour and amount hour, just stay the bottom of blowout prevention cleaner inner pressure relief part, as Fig. 2 diagram 4. shown in: the inner pressure relief part is not because there being enough pressure can not rise, thereby oil spill is stayed bottom the inner pressure relief part and can not flowed out the blowout prevention cleaner.

When leakage of oil and injection pressure are large, just inner pressure relief structure (4. Fig. 2 illustrates) is upwards boosted, with in the blowout prevention cleaner along rank mutually, thereby make oil that spray leaks in blowout prevention cleaner the latter half, at last from Fig. 2 diagram 6. tiltedly the lower oil pipe that goes out outwards flow away.

For preventing from spraying leakage of oil pressure when large, and the inner pressure relief structure is made progress jack-up and blowout prevention cleaner Inner along rank mutually, thus cause part oil from, the blowout prevention cleaner spills, and at this moment sprays the first half that oil spill is held in the mouth mutually at inner pressure relief structure and blowout prevention cleaner.

The oil that the first half spray is leaked reaches constant weight, and the latter half oil reduces, and pressure is greater than the latter half thrust, and in this case, the inner pressure relief structure is descended by action of gravitation, thereby 6. the spray oil spill tiltedly plays flowline to flow out the blowout prevention cleaner from Fig. 2 diagram.

Here blowout prevention cleaner inner pressure relief part has just become one to utilize thrust and the constantly automatic up and down adjuster of Action of Gravity Field.

In the blowout prevention cleaner pressure reduction structure course of work, produced three decompression circles:

1. inner pressure relief structural base is an independently little decompression circle;

2. when inner pressure relief structure rising is held in the mouth mutually with blowout prevention cleaner Inner edge, the decompression circle of blowout prevention cleaner the latter half and the decompression circle of the first half.

This up and down two decompression circles under thrust and action of gravitation, constantly the automatically up and down periodic duty of blowout prevention cleaner inner pressure relief structure, the spray oil spill is continuously outflowed from tiltedly lower flowline.

The utility model uses new packing, shown in Fig. 2 diagram (10), adds the sealing packing box, and it is by three kinds of different materials: oil resisting paronite packing, special graphite soft graphite (expanded graphite) and resin carbon composite are made.It has the characteristics such as abrasion resistance, elasticity, crushing resistance, sealing.

Claims

1. oil pumper blowout prevention cleaner, this oil pumper blowout prevention cleaner comprises following part: packing box; Blowout prevention cleaner inner pressure relief structure; Tiltedly lower flowline; Circular push rod; Sealed jacketed box; With the oil pumping steel pipe; It is characterized in that: wherein packing box and blowout prevention cleaner welding, part is inner at the blowout prevention cleaner on the packing box, and inner pressure relief partly rise with the blowout prevention cleaner in along rank mutually.
