Description
Technical field
Patent of the present invention relates to the fluid end profit on the reciprocating pressure break plunger displacement pump in the conveyance fluid equipment of a kind of oil field
Sliding system and device, it is adaptable to the oil circuit of high-power pressure break pumping installations hydraulic end lubricating system improves.Relate to oil-gas field drill
Equipment manufacturing technology field.
Background technology
Current reciprocating pressure break plunger displacement pump is widely used in each elephant field, along with the oil well drilling degree of depth not
Disconnected increasing, fracturing pump applying working condition condition the most constantly deteriorates, and market proposes higher requirement to the serviceability of fracturing pump, and moistens
Sliding system be to ensure that again that fracturing pump normally uses to pass factor so that good lubrication extends making of packing_seal part
With life-span and the normal use of guarantee fracturing pump.Pressure break hydraulic end of plunger pump lubricating system is widely used in the market two
The mode of kind: one is that---------choke valve----packing is managed in distribution to oil filter to lubricating oil, this from fuel tank through external gear pump
Lubricating system needs a power takeoff providing external connection power source, can increase the power total load of electromotor output and take change
The power takeoff interface of speed case;The second way is lubricating oil---distribution pipe---throttling through pneumatic diaphragm pump from lubrication gas tank
Valve---packing lubricate, this lubricating system be required to provide external gas source device, install numerous and diverse, take limited equipment
Assembly space.Due to higher to big pump pressure and displacement requirements when pressure break operating mode, cause fracturing pump packing assembly life-span shorter,
Often there is fracturing fluid to enter in stuffing box along with plunger, lubricating oil is polluted, causes lubricating oil can not recycle and reuse, no
Only can cause the waste of resource and pollute environment.
Summary of the invention

Power, is adjusted the lubricating oil pressure entered in distributing valve by choke valve, and after being adjusted to convenient pressure, lubricating oil is by distributing valve
Three outlets after check valve, enter hydraulic end sealed assembly by lubricating oil pipe respectively sealing member be lubricated, lubricate
After waste oil carry out collecting by the draw-off tray bottom fracturing pump fluid end and return in fluid end grease-box, formed and lubricate back
Road.Manually ball valve carries out blowdown cleaning to grease-box, and the outlet distance tank bottoms of grease-box also has one end distance,
Can be used for depositing the residue in fuel tank and water, extend the use cycle of lubricating oil, check valve is possible to prevent gear pump to quit work
The backflow of rear lubricating oil.This fracturing pump fluid end self-lubricating mode can not ensure that packing obtains in the case of external power taking
To sufficiently lubrication, it is also possible to lubricating oil is reclaimed and is reused by filters.
Advantage of the present invention is as follows:
1, grease pump is integrated in big pump pinion axial end by the present invention, it is not necessary to external power takeoff, makes big pump power be filled
Divide, reasonably use, reduce assembly cost and complete machine layout difficulty.
2, fluid end grease-box is integrated in fluid end draw-off tray bottom by the present invention, carries out lubricating oil reclaiming and repeats profit
With, after oil filter thick, thin filters, form lubricating loop by gear pump, it is to avoid residue enters gear pump and gear pump is caused damage
Bad.
3, the fluid end grease-box bottom of the present invention is provided with the manual ball valve of blowdown, it is simple to the discharge of waste oil and oil
The cleaning of case;The oil-out distance bottom of fuel tank also has certain distance, can be used for deposition fraction and enters residue and the water of fuel tank, keeps away
Exempt to enter gear pump, gear pump is caused damage.
4, hydraulic end lubricating system of the present invention is configured with Pressure gauge, choke valve, can regulate lubricating oil pressure at one
Within the scope of He Shi, it is ensured that fluid end can sufficiently be lubricated, delay the abrasion of sealing member, extend the use longevity of packing
Life.
