Description
Technical field
The utility model is related to reciprocal pump technical field, more particularly to a kind of power end using force feed,
The integrated connecting rod ASSY of splash lubrication.
Background technology
The lubricating system of moving component generally can be divided into Reciprocatin pump power end, and one kind is force feed (forced feed lubrication),
One kind is splash lubrication, and conventional is that mating selection lubricating system, power >=185KW, plunger force are carried out by power and plunger force
>=500 kilograms mating for force feed, 500 kilograms of mating selected as splash lubrications of power ＜ 185KW, plunger force ＜.The pressure
The route of hydrodynamic lubrication is often arranged to oil inlet in bent the tip of the axis, and position is led directly to and end crank throw on the center line of axis
Center is turned by each bent axle and a upper oilhole is accounted at load bar, and the major part center of connecting rod is communicated with fuel-displaced at the axle sleeve pin of microcephaly,
Result in formation of a force feed route, to meet the lubrication of the operation part running surface such as bent axle, connecting rod, crosshead, such as Fig. 1
It is shown.The splash lubrication is the lubricating system of no pressure, generally the baseplane of the upper crosshead of oil level line leaching, is rotated by bent axle
When oil got rid of be flowed into oil scraping plate box in back oil sump, be allocated oil site, enter crosshead top
In oilhole, lubrication crosshead pin axle sleeve in microcephaly's axle sleeve pivot pin of connecting rod is imported into, partly enters the bottom lubrication of crosshead
