Abstract
Oil sealing assisted by a kind of water injection pump bearing shell, comprising: disc (1), clip (2), packing (3).It is characterized in that: described water injection pump bearing shell assists the packing of oil sealing (3) overcoat disc (1), disc (1) is clamped by clip (2).The utility model is applicable to oil field centrifugal tundish bearing shell oil sealing auxiliary seal, structure is simple, installation, disassembling section are conveniently, must not remove and reinstall more component during installation, repair time of bearing shell oil sealing seepage shortens to original 1/3, alleviate the labor intensity of workman, shorten pump and repair the time, rate when improving the operation of water injection pump.
Description
Technical field
the utility model relates to oil field centrifugal tundish seal arrangement, and specifically oil sealing assisted by a kind of water injection pump bearing shell.
Background technique
the large centrifugal water injection pump that current oil field flood pattern uses, all adopts the lubricant oil of integrated oil seal to bearing shell to seal.After long-time high speed operation, integrated type bearing shell oil sealing is because of reasons such as uneven wearing and tearing, and sealability declines gradually, and the problem of oil seepage occurs.For ensureing the normal operation of equipment, just need to change oil-sealing arrangement.Bearing shell oil sealing is little, a lightweight auxiliary accessories of volume on water injection pump, but owing to being integral design, must remove and reinstall more component during replacing, and labor strength is large, and it is long that the time repaiied by pump, rate when affecting the operation of water injection pump.
Summary of the invention
the purpose of this utility model is exactly in view of the foregoing defects the prior art has, designs a kind of water injection pump bearing shell and assists oil sealing.
the utility model is realized by following technical proposals:
the utility model comprises: disc, clip, packing.Described water injection pump bearing shell assists the packing overcoat of oil sealing disc, and disc is clamped by clip.
it is boss loop configuration that above-mentioned water injection pump bearing shell is assisted in the middle of the disc in oil sealing, is suppressed forming by 5 ~ 10 layers of sheet copper.
above-mentioned water injection pump bearing shell assists the packing in oil sealing to be that rubber plate makes.
the beneficial effects of the utility model are: be applicable to oil field centrifugal tundish bearing shell oil sealing auxiliary seal,
structure is simple, installs, disassembling section is convenient, must not remove and reinstall more component during installation, and repair time of bearing shell oil sealing seepage shortens to original 1/3, alleviates the labor intensity of workman, shortens pump and repair the time, rate when improving the operation of water injection pump.
Accompanying drawing explanation
the on-the-spot application structure schematic diagram of Fig. 1-the utility model.
in figure, 1. disc, 2. clip, 3. packing, 4. pump shaft.
Embodiment
below in conjunction with accompanying drawing, enforcement of the present utility model is further elaborated:
water injection pump bearing shell assists oil sealing to be made up of disc 1, clip 2, packing 3.Described water injection pump bearing shell assists the outer cover of the packing 3 be rolled into by rubber plate of oil sealing the disc 1 suppressed by 8 layers of sheet copper, and disc 1 is clamped by clip 2.
operating procedure
first, appliances for labor protection have been dressed, preparation tool apparatus.
secondly, lay down bearing support drain oil plug, lubricant oil is put only, remove bearing support top automation temperature indicator.
3rd, lay down bearing support fastening screw and bearing gland and bearing support fixing pin, take out water injection pump bearing shell.
4th, oil-resistant rubber slab packing 3 and shaping copper sheet disc 1 are wrapped in the position of pump shaft 4 near original oil sealing successively, then tighten with clip 2.
5th, lower bearing, top bearing shell, fixing pin, bearing gland are installed successively, tighten retaining screw, automation temperature indicator is installed.
6th, first-class drain oil plug, filling new oil.
Claims (3)
1. an oil sealing assisted by water injection pump bearing shell, comprising: disc (1), clip (2), packing (3); It is characterized in that: described water injection pump bearing shell assists the packing of oil sealing (3) overcoat disc (1), disc (1) is clamped by clip (2).
2. oil sealing assisted by water injection pump bearing shell according to claim 1, it is characterized in that: be boss loop configuration in the middle of described disc (1), suppressed forming by 5 ~ 10 layers of sheet copper.
