Description
Technical field
The utility model relates to the seal arrangement on a kind of oil drilling and extracting equipment, particularly a kind of sealer with assembled.
Background technique
Oil field operation plunger pump is well cementation, and one of nucleus equipment of fracturing unit, is widely used in reinforcing oil well fracturing work.Current oil field operation plunger pump power end power-conversion is that the pressure of liquid mainly still relies on sliding cylinder extrusion liquid, overflow to prevent power end lubricant oil, prevent fluid end liquid mixture to be mixed in power end lubricant oil as cement slurry etc. simultaneously, between power end and fluid end, be provided with seal arrangement.Usually in fluid end, design packing nut seal device invades in power end to prevent fluid end dirt, arranges separate Oil sealing assembly to prevent the leakage of lubricant oil at power end.But in use, plunger translation between power end and fluid end back and forth, it is open architecture that power end installs the support of oil sealing, and its oil sealing place usually exists leak case, also usually there is clean water mud of not swiping from fluid end plunger surface out.
By Whole Equipment size restrictions, between power end and fluid end, span is smaller, and this span also needs the smooth dismounting ensureing packing nut on fluid end.More traditional mentality of designing arranges several roads oil sealing on the oil sealing base assembly of power end, but the reduction increasing free space when will cause the dismounting of packing nut of oil sealing quantity.
Model utility content
the purpose of this utility model is to provide a kind of sealer with assembled, and not only volume is little for he, good sealing effect and can remove the dirt of plunger surface.
The technological scheme realizing the utility model object is: a kind of sealer with assembled, comprise separation oil sealing base, the inwall of this separation oil sealing base and plunger contact, groove is had along the inwall separating oil sealing base, first oil sealing is arranged in this groove, the side of described separation oil sealing base is plunger pump power end opposite side is hydraulic end of plunger pump, it is characterized in that: be furnished with the second oil sealing and scrubbing seal ring vertically successively close to the side of fluid end separating oil sealing base, the second described oil sealing and scrubbing seal ring to be arranged in a connection set and by this connection set with separate oil sealing base and be connected.
And described connection set is combination seal fixing frame, the inwall of described combination seal fixing frame has twice groove vertically, and the second oil sealing and scrubbing seal ring are separately positioned in this twice groove.
And described separation oil sealing base also has a cover plate close to the side of fluid end, all have projection on the inwall of this cover plate and on the outer wall of combination seal fixing frame, the projection on the outer wall of described combination seal fixing frame embeds between the projection on separation oil sealing base and cover plate inwall.
And described separation oil sealing base and cover plate are bolted.
And described separation oil sealing base is connected by the mode of welding with cover plate.
And described separation oil sealing base is connected by the mode of riveting with cover plate.
And projection on described combination seal fixing frame outer wall and be provided with obturator between cover plate.
And described obturator is round section joint ring.
And described separation oil sealing base separates oil sealing seat cushion close to the end face of power end is also provided with.
The utility model has the advantage of: 1. combination seal fixing frame and the second oil sealing form closed oil groove, good sealing effect.2. the second oil sealing and scrubbing seal ring are all arranged in combination seal fixing frame, and volume is little, and enough spaces have been reserved in the dismounting for packing nut.3. be provided with scrubbing seal ring in the side close to fluid end, the dirt scrapings such as the cement on its surface can be wiped clean in the process of plunger translation vertically, prevent dirt to the corrosive action of oil sealing, when plunger is static, also effectively can prevent entering of the things such as dust, extend the working life of oil sealing.
Accompanying drawing explanation
Fig. 1 is the structural representation of sealer with assembled left view;
Fig. 2 is the plan view of sealer with assembled.
Embodiment
the utility model is described further below with reference to embodiment see Fig. 1 ~ 2.
Seal arrangement on a kind of oil drilling and extracting equipment, particularly a kind of sealer with assembled, comprise and separate oil sealing base 1, the inwall of this separation oil sealing base 1 contacts with plunger 11, groove is had along the inwall separating oil sealing base 1, first oil sealing 3 is arranged in this groove, the side of described separation oil sealing base 1 is plunger pump power end opposite side is the fluid end of plunger pump, it is characterized in that: be furnished with the second oil sealing 8 and scrubbing seal ring 10 vertically successively close to the side of fluid end separating oil sealing base 1, the second described oil sealing 8 and scrubbing seal ring 10 to be arranged in a connection set and by this connection set with separate oil sealing base 1 and be connected.
Second oil sealing 8 and scrubbing seal ring 10 are connected to by a combination seal fixing frame and separate on oil sealing base 1, reduce the volume of sealer with assembled, while combination seal fixing frame 9 and the second oil sealing 8 form closed oil groove, good sealing effect.
