Abstract

The utility model discloses a plunger packing protector for a plunger pump. The plunger packing protector for the plunger pump comprises a plunger pump body which comprises a pump actuating mechanism and a pump operation mechanism, and a plunger which is arranged between the pump actuating mechanism and the pump operation mechanism is penetratingly connected with the pump operation mechanism and in transmission connection with the pump actuating mechanism. The plunger packing protector for the plunger pump is characterized in that the pump operation mechanism comprises a high-pressure hydraulic end cylinder body, and a low-pressure suction manifold, a valve, a plunger portion, a valve and a pressure cover are sequentially arranged on a pipeline which is arranged at the end of the outer side of the high-pressure hydraulic end cylinder body; the plunger penetrates through the high-pressure hydraulic end cylinder body and is communicated with the plunger portion; a packing protector is arranged between the plunger and the high-pressure hydraulic end cylinder body. The plunger packing protector for the plunger pump has the advantages that service lives of the plunger and the packing are prolonged in gravel packing operation, manual cost for replacement of the plunger and the packing is reduced, material cost is reduced as well, and operation risk in replacement of the pump is lowered.

Description

A kind of plunger pump plunger packing protector
Technical field
The utility model belongs to a kind of plunger pump plunger packing protector.
Background technique
Generally be applied at present the packing of plunger pump, employing be combined high-voltage packing, but can often there is the situation of rapid wear in this plunger, main cause is:
(1) combined type packing is due to the wedge-shaped crevice of special seal design forming, is easy to be filled with gravel in liquid because relative movement is brought in wedge-shaped crevice.
(2) plunger and packing are worn and torn by wedge shape cobble-stone simultaneously, and cause plunger to be pulled with packing_seal, lose efficacy.
(3) plunger surface hardness cannot be brought up in gravel hardness.
(4) change plunger and packing is time-consuming, effort, increase operating cost.
(5) between plunger and packing, poor sealing has affected normal gravel pack operation, has increased operating risk.
Model utility content
In order to address the above problem, the utility model provides a kind of damage that not only reduces packing, also can prevent that steel plunger is worn simultaneously, has the plunger pump plunger packing protector of the feature of reusing simultaneously.
For addressing the above problem, the technological scheme that the utility model adopts is:
A kind of plunger pump plunger packing protector, comprise plunger pump body, plunger pump body comprises pump power mechanism and pump work mechanism, between pump power mechanism and pump work mechanism, be provided with plunger, described plunger runs through and connects pump work mechanism, and plunger driving connects pump power mechanism, it is characterized in that: described pump work mechanism comprises high pressure fluid end cylinder body, the outboard end of high pressure fluid power cylinder end body is provided with pipeline, is disposed with low pressure suction manifold, valve, plunger portion, valve and gland on pipeline; Described plunger runs through high pressure fluid end cylinder body and is communicated with plunger portion; Before described plunger and high pressure fluid end cylinder body, be provided with packing protector.
As a kind of technological scheme of optimization, described plunger is slidably connected in the slideway in high pressure fluid end cylinder body, on the inwall of slideway, is provided with packing protector; In described slideway, be also provided with packing gland, portion's oil ring, combination packing-take over a business, combine packing-back pressure ring, combine packing-high compression ring.
As a kind of technological scheme of optimization, described packing protector comprises logical pressure ring-front ring, logical pressure ring-rear ring, foreign material cleaning ring is set; The inside of described logical pressure ring-front ring and logical pressure ring-rear ring is provided with pressure conduction trough.
Owing to having adopted technique scheme, compared with prior art, the utility model has been installed packing protector, and in common gravel pack operation or pressure break gravel pack operation, protector provides the working environment of relative clean to packing and plunger.It is not moved reciprocatingly in there is no the fill liquid environment of gravel, greatly improve in gravel pack operation plunger and packing working life, not only reduce the cost of labor of changing plunger and packing, also lowered cost of material, also reduced the operating risk that need to change pump simultaneously.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
Accompanying drawing explanation

Embodiment
Embodiment:
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, a kind of plunger pump plunger packing protector, comprise plunger pump body, it is characterized in that: described plunger pump body comprises bearing 2 and plunger 13, bearing 2 is arranged on bearing support 1, bearing 2 connects plunger 13 by connecting rod 3, and be provided with wrist pin 4 between connecting rod 3 and plunger 13, crosshead 16, pull bar 15 be connected snap close 14, one end of plunger 13 is connected with high pressure fluid end cylinder body 6, and in high pressure fluid end cylinder body 6, be provided with the passage with the relative use of plunger, in passage, be disposed with low pressure suction manifold 12, suck valve valve 11, valve head position-limited lever 10, plug gland 9, discharge valve valve 8 and gland 7, described plunger 13 is provided with packing protector 5 before with high pressure fluid end cylinder body 6.
In the present embodiment, described plunger 13 is slidably connected in the slideway in high pressure fluid end cylinder body 6, is provided with packing protector 5 on the inwall of slideway.In described slideway, be also provided with packing gland 21, portion's oil ring 22, combination packing-take over a business 23, combine packing-back pressure ring 24, combine packing-high compression ring 25
Described packing protector comprises logical pressure ring-front ring 31, logical pressure ring-encircle afterwards 32, foreign material cleaning ring 33 is set.。The inside of described logical pressure ring-front ring 31 and logical pressure ring-encircle afterwards 32 is provided with pressure conduction trough 34.
The utility model has been installed packing protector, and in common gravel pack operation or pressure break gravel pack operation, protector provides the working environment of relative clean to packing and plunger.It is not moved reciprocatingly in there is no the fill liquid environment of gravel, greatly improve in gravel pack operation plunger and packing working life, not only reduce the cost of labor of changing plunger and packing, also lowered cost of material, also reduced the operating risk that need to change pump simultaneously.
