Description
Technical field
The utility model relates to a kind of novel plunger pump sealed letter, in particular, relates in particular to a kind of chip that reduces to the wearing and tearing of plunger and the novel plunger pump sealed letter that is provided with lubricating structure.
Background technique
The working principle of the sealed letter of various model plunger pumps is similar in the oil field flood pattern; Its working principle is: push the copper gland through the rotation packing gland; The copper gland compresses packing, thereby the annular space of sealed plunger and sealed letter behind the lateral expansion is taken place by vertical extruding packing.But the problem that exists at present is: the life cycle of packing and plunger is shorter; Packing is changed the back and is begun leakage after operation a period of time; And the protective layer of plunger surface is worn easily and produces pit; Cause severe leakage, not only pump efficiency reduces greatly, and raises because of the materials consumption increase causes the water filling cost.
The main cause that draws seal failure through the abrasion condition investigation and analysis to packing leakage and plunger has the following aspects: at first be corrosion and wearing and tearing, contain acid ion in the fed sheet of a media, plunger is played corrosive action; In addition, after the termination of pumping, because plunger surface adheres to the sewage that is leaked out by packing; Be parked in for a long time in the air, plunger is caused corrosion, produce tunnel and pit; And the crystal grain of separating out after long-term the stop, the to-and-fro motion entering sealed letter with plunger has strengthened the wearing and tearing to plunger and packing.Be the friction of plunger and packing in addition; Plunger pump is to lean on the to-and-fro motion of plunger to suck with drain; The reciprocal time of plunger is up to 230-370 times/minutes; Owing to the high speed to-and-fro motion makes plunger and packing because of violent friction produces high temperature, cause packing to produce sintering phenomenon, simultaneously because friction-produced trace chip.After chip and medium are brought into sealing surface together, quickened the wearing and tearing of packing and plunger, the packing wastage increases.
Summary of the invention
The utility model provides a kind of chip that reduces to the wearing and tearing of plunger and the novel plunger pump sealed letter that is provided with lubricating structure in order to overcome the shortcoming of above-mentioned technical problem.
The novel plunger pump sealed letter of the utility model; Comprise gland and the gland that matches with gland; Said gland is provided with the cavity that matches with plunger; Said gland is provided with the gland cavity that matches with gland, and its specialization is: circular groove and outer annular groove in offering respectively on the internal surface of said gland and the outer surface, and the position of interior circular groove and outer annular groove is corresponding and be connected through several through holes; Be provided with the lubrication hole that several can make outer annular groove be in communication with the outside with the corresponding position of outer annular groove on the said gland.Gland extends through on the plunger through the cavity on it, and gland also extends through on the plunger through the gland cavity, and in the process of using, gland extend in the gland cavity, and through the extruding realization seal action of gland to gland.Interior circular groove and outer annular groove are separately positioned on the internal surface and outer surface of gland, and are positioned at the same cross-section of gland, and interior circular groove is connected through through hole with outer annular groove.Because interior circular groove is positioned at the periphery of plunger, in the process that plunger and gland relatively move, the chip that to-and-fro motion produces can enter into interior circular groove, has reduced the wearing and tearing of chip to plunger effectively, has increased the working life of plunger.On gland, lubrication hole is set with the corresponding position of outer annular groove; Can realize that lubricant oil flows in the outer annular groove; And circular groove in entering into through through hole, and then realize lubricated and cooling effect to plunger, gland, also prolonged the working life of plunger and gland effectively.
The novel plunger pump sealed letter of the utility model, said gland is divided into two sections that external diameter does not wait, and interior circular groove and outer annular groove are arranged on one section big gland of diameter.Be arranged on interior circular groove and outer annular groove on big one section of diameter, help being provided with the bigger circular groove of the degree of depth, also can not influence the intensity of whole gland, help guaranteeing the working life of gland.
The novel plunger pump sealed letter of the utility model, said plunger is provided with the packing body that matches with gland (6), and gland is arranged between packing body and the gland; The outer surface of said packing body is provided with outside thread, the internal surface of gland be provided with the packing body on the internal thread that matches of outside thread.In the process of using, through externally threaded cooperation the on the internal thread on the gland and the packing body, can realize being fixedly connected of gland and packing body, and can realize that gland exerts pressure the assurance sealing to gland.
The novel plunger pump sealed letter of the utility model, the quantity of the through hole between said interior circular groove and the outer annular groove is 4～8, the quantity of the lubrication hole of gland setting is 2～8.
The novel plunger pump sealed letter of the utility model, the material of said gland is a copper.Gland adopts copper as material, helps guaranteeing wear-resisting, the decay resistance of gland.
The beneficial effect of the utility model is: the utility model is through being provided with interior circular groove on the internal surface of gland; The chip that makes gland and plunger in relative to-and-fro motion process, produce enters into wherein; Effectively avoided the wearing and tearing of chip, increased the working life of workpiece plunger and gland; The outer annular groove that communicates with interior circular groove through outer surface setting at gland; And on the gland with on the corresponding position of outer annular groove lubrication hole is being set; Make lubricant oil can enter into the plunger place easily, realized lubricated and cooling effect effectively plunger, gland.Before playing pump; The lubricant oil that adds can store in interior circular groove and outer annular groove; Plunger, gland and packing body are played good lubrication, and alleviated the dry grinding phenomenon of packing and plunger, had the effect that alleviates surface friction drag, reduces starting torque and reduction inrush current.After termination of pumping, seal through filling machine oil, prevented getting rusty of plunger, gland effectively, prolonged the working life of part.The utlity model has the advantage that spillage of material is low, maintenance workload is low, maintenance cost is low, the operational efficiency of plunger pump is high.
