Abstract
A cement slurry piston pump is provided for a fixed well cement slurry mixing equipment that the slurry density can be automatically controlled, which comprises a body of the pump and a piston in the body, the body of the pump is provided with a lubricant road leading to the piston, one side of the export of the lubricant road is provided with a seal in order to prevent leakage, another side of the export of the lubricant road is provided with a ring seal. The technology project is able to effectively prevent oil leakage, reduce oil quantity and avoid environmental pollution caused by the oil leakage.
Description
Technical field
The utility model relates to a kind of cement slurry plunger pump, is used for the mixing well cementing cement slurry equipment that cement slurry density can be controlled automatically.
Background technique
In the ocean or land well cementing operation of petroleum production industry, need to adopt cement slurry cementing equipment, this equipment should be able to by set that density is come mix cement slurry and with its plunger pump continuously with under the cement slurry input well.Existing plunger pump comprises pump and the plunger that is positioned at the pump housing, and the body of pump has the oil leab that leads to plunger, and a side of oil duct outlet end is provided with Sealing, during work, in the mode of flowing automatically lubricant oil is imported in the pump lubricated reciprocating plunger.Problem is: only depend on the Sealing of oil duct outlet end one side still to be difficult to prevent oil leak.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of cement slurry plunger pump, sets up Sealing by selecting suitable position, makes it can prevent oil leak effectively.
The technological scheme that solves the present technique problem is when comprising aforementioned formation, and its improvements are: the opposite side at the oil duct outlet end is provided with lip ring.
The technical program advantage compared to existing technology is: owing to set up lip ring at the opposite side of outlet end, like this, Sealing is positioned at the both sides of oil outlet, more adapt to plunger reciprocating on two different direction to lubricating and prevent the requirement of oil leak, promptly constitute a lubricated district between the Sealing of oil outlet both sides, Sealing then stops lubricant oil to flow out outside the district.It can not only prevent oil leak effectively, can also reduce simultaneously and use oil mass, avoids leaking the pollution of oil to environment.
Description of drawings
Accompanying drawing is the integrally-built sectional view of signal the utility model.
Embodiment
With reference to accompanying drawing, the described plunger pump of the technical program comprises: the pump housing 3 and the plunger 1 that is positioned at the pump housing 3, and the body of pump has the oil leab 4 that leads to plunger 1, and a side of oil duct 4 outlet end 5 is provided with Sealing 8, in order to prevent oil leakage, be provided with lip ring 10 at the opposite side of oil duct 4 outlet end 5.
Further technological scheme is: oil duct 4 outlet end 5 one sides can be Sealing groups 8, sealing part 8 is pressed pressure ring 6, Sealing 7 alternate layouts, the lip ring 10 of opposite side is inlaid in the sealing seat 11, its oil sealing surface is towards the outer wall of plunger 1, between the sealing seat 11 and the pump housing 3, be embedded with " O " shape seal ring 9, between sealing seat 11 and Sealing 8 for being connected with oil duct 4 and to the cloth food tray 12 of plunger 1 guiding lubricant oil, the nut 2 that is positioned at the pump housing 3 one ends is from axially compressing sealing seat 11, cloth food tray 12, pressure ring 6 and Sealing 7 successively.
