Description
Technical field
Patent of the present invention relate in the reciprocating plunger pump in a kind of oil field conveying fluid device imitative SPM600 pump and
The lubricating system device of the 1000 big pumps of the plug-in reduction box of type modified, it is adaptable to this type of pumping installations power end crankshaft connecting rod system
The oil circuit of lubricating system improves.Relate to oil-gas field drill equipment manufacturing technology field.
Background technology
Plunger displacement pump, owing to having the remarkable advantages such as compact conformation, volumetric efficiency height, high pressure huge discharge, has been widely used for
The occasions such as oil field drilling is repaiied, cemented the well, pressure break.Plunger displacement pump be broadly divided into power end assembly, fluid end assembly, power end lubricating system,
The parts such as hydraulic end lubricating system, wherein lubricating system is the necessary factor that big pump persistently normally works, in order to reduce kinematic pair
Between abrasion, lubricating oil film need to be formed at working surface, keeping the gap between kinematic pair, and take away because of fricative
Heat, scrap；For big pump, every place having relative motion is both needed to be lubricated, and on the one hand extends making of seal
With the life-span, on the other hand prevent the operative minor of relative motion, as crosshead and cylinder liner surface occur killing because of overheated and burn out
The phenomenon of big pump.Thus good lubricating system is to ensure that the necessary condition that big pump normal continuous operates, particularly high in oil field
The big pump working under pressure, heavy load operating mode.
At present, domestic and international plunger displacement pump picture imitates SPM600, this kind of power end of plunger pump profit with plug-in reduction box of 1000 type pumps
Sliding used oil circuit is designed as：Lubricating oil is through gear oil pump----oil filter---, and overflow valve is divided into two, and a process is overflow
Stream valve returns to grease-box after adjusting pressure, and another is through lubrication supervisor's---guide plate--crosshead--small end of connecting rod---cross
Head pin---link body centre bore---big end tile---bent axle.This lubricating system its be disadvantageous in that：Lubricating oil
Have to pass through crosshead, crosshead pin, small end of connecting rod lubrication after could enter big end, bent axle is lubricated with bearing shell,
Crankshaft oil-way is long, has of a relatively high requirement, once oil pressure deficiency or link body center oil to lubrication pressure and discharge capacity
Hole produces high temperature locking pump chamber because the residue blocking in lubricating oil easily causes because of oil starvation between bent axle and connecting rod bearing shell
Phenomenon, has a strong impact on big pump normal and uses and even result in big pump and directly scrap.
Content of the invention
It is an object of the invention to overcome tradition imitative SPM600 pump, 1000 pump power end crankshaft connecting rod system lubricating systems
Deficiency, from lubricant passage way, lubricating system is improved, a kind of Novel reciprocating type power end of plunger pump lubricating system is provided.
Object above is achieved through the following technical solutions：
A kind of Novel reciprocating type power end of plunger pump lubricating system of the present invention, is characterized in that by joint, lubricates thin oil pipe, curved connects
Head, straight joint, main oil pipe, bent axle, "O"-ring, swivel joint, bent axle swivel joint, crankshaft-link rod, crosshead, crosshead pin,
The part composition such as small end of connecting rod tile.Joint, bent sub, straight joint are connected with pump case by screw thread one end, the other end and profit
Sliding thin oil pipe is connected, and main oil pipe is welded on inside pump case, and one end is connected with bent sub, and one end is connected with lubricating oil oil-in, bent
Axle is arranged on inside pump case, and crankshaft-link rod one end is connected with bent axle, and one end is fixed on inside crosshead by crosshead pin, even
Bar microcephaly watt is embedded in crankshaft-link rod, and bent axle swivel joint one end is connected with oil-in, and one end is threadedly attached in rotation
On joint, swivel joint is sealed in inside bent axle by "O"-ring, is fixed by bolts to crankshaft end-face.
It is drilled with oilhole inside bent axle, be used for forming grease channel；Crankshaft end-face is drilled with screwed hole, is used for connecting institute
State bent axle swivel joint；Bent axle swivel joint is got on the bus and is had groove, is used for installing described "O"-ring and seals；Bore on main oil pipe
There is screwed hole, be welded on inside pump case；Lubricating oil pipe is used for connecting main oil pipe and required lubricating component；Connect on bent axle swivel joint
Being connected to can be with 360 ° of described swivel joint rotating, as the external interface of crank lubricating.
The operation principle of the present invention：
From fuel tank through gear oil pump,----oil filter---overflow valve is divided into two to lubricating oil, and one adjusts pressure through overflow valve
Returning to grease-box after power, lubricant passage way is divided into two-way by three-way connection by another, road lubrication supervisor's---guide plate--ten
Prefix--small end of connecting rod---crosshead pin；Another road lubricating oil pipe---bent axle swivel joint---swivel joint---bent axle---
Big end tile, last two-way lubricating oil returns to fuel tank after all collecting in pump case.
Advantages of the present invention is as follows：
1st, the present invention is by boring internal oilhole on bent axle, forms grease channel, fully moistens bent axle, crankshaft-link rod
Sliding, overcome the imitative SPM600 of tradition, the oil circuit in 1000 pump lubrication modes long, easily cause crankshaft connecting rod lubrication not enough and burn out big
The shortcoming of pump, improves the reliability and security of big pump, it is ensured that big pump can continue normally to work.
2nd, the present invention uses branch lubrication to crosshead and crankshaft-link rod, and lubricating oil pressure requirement is wanted than conventional lubrication mode
Low, gear oil pump oil pressure is required relatively loose, cost-effective.
