Abstract
The utility model discloses an asymmetric oil circuit cross head pin of JB6M50 compressor, including cylindrical shank, the shank lateral wall is equipped with three in to the shank and communicates respectively to the oilhole of central through hole, and three oilholes are in the different radial of same circumference, and three oilholes are each other at a distance from 120 degrees on the circumference. The utility model discloses the intensity of multiplicable compressor cross head pin and lubricated effect, when reducing the shut down time scalar sum operation post of compressor, greatly reduced put the emission of waste gas, directly reduced the pollution to the surrounding environment, simultaneously because the compressor examines and repair the reduction of number of times, also reduced when examining and repairing the greasy dirt to the negative effects of post environment, production economic benefits has also been improved to the while.
Description
Technical field
This utility model relates to compressor crosshead pin field, specifically a kind of asymmetric oil circuit crosshead pin of JB6M50 compressor.
Background technology
nullLarge-scale reciprocating-piston nitrogen-hydrogen compressor is the crucial power-equipment in commercial production，At metallurgy、Petrochemical industry、All conglomeraties such as Coal Chemical Industry or even boats and ships use extensively，In recent years，Development and the continuous enlargement of each manufacturing enterprise production capacity along with equipment manufacture，Compressor Manufacturing is also increasingly to high thrust、Multiple row cylinder develops，Now domestic there are 80 tons of piston forces、The Large-scale Reciprocating Compressor of seven row pistons，The safety of compressor、Steady running is to improving production efficiency、Reduce consumption and seem more and more important，Also all the more important particularly in its " heart " status in Nitrogenous Fertilizer Industry，And compressor connects piston and connecting rod vitals is exactly crosshead，The oil supplying hole of crosshead pivot pin，Traditional crosshead pin oilhole is all symmetrical machining，It it is a straight-through oilhole or being two passes through oilhole mutually，Fuel delivery is had certain impact by the former，Easily cause oil film uneven，Due to for the easy burn-back copper sheathing of shortage of oil，It is greatly reduced the intensity of crosshead pin self，Often pin fracture is occurred to break the accident of piston，Change crosshead pin seed oil eye into asymmetric oil circuit，Make pin oilhole be 120 ° uniform，Thus increasing the intensity of crosshead pin self，Crosshead pin is avoided to rupture，Crosshead pin can form again uniform oil film in running up simultaneously，Also solve due to the problem for shortage of oil burn-back copper sheathing.
The asymmetric oil circuit crosshead pin of JB6M50 compressor: by the restriction of fuel system, big end lubricating system generally has Crankshaft Machining to go out hollow oilhole and crosshead pin processes hollow oilhole two kinds selection, because bent axle importance or unit layout need, more than crosshead pin, compressor processing industry is typically chosen on crosshead pin and is processed into hollow oilhole, and result makes its intensity be substantially reduced.As it is shown in figure 1, traditional crosshead pin oilhole is what interpenetrate, passes through and mistake mutually in " ten " font in the middle of pin, reduce the intensity of pin to a great extent, cause oilhole place fracture of being everlasting during pin.
Utility model content the purpose of this utility model is to provide a kind of asymmetric oil circuit crosshead pin of JB6M50 compressor, to solve the prior art JB6M50 cross head pin of compressor problem at oilhole place easy fracture.
In order to achieve the above object, the technical scheme that this utility model adopts is:
The asymmetric oil circuit crosshead pin of JB6M50 compressor, include cylindrical shank, shank central coaxial is provided with central through hole, it is characterized in that: shank sidewall is provided with three roads in shank and is respectively communicated to the oilhole of central through hole, three road oilholes respectively along shank the difference of same circumference be radially arranged, and three road oilholes are circumferentially spaced 120 degree.
This utility model adopts asymmetric oil circuit technology, make oilhole be 120 ° uniform, thus increasing the intensity of crosshead pin self, compensate for symmetrical four hole oil circuits and reduce the deficiency of pin intensity, crosshead pin is avoided to rupture, crosshead pin can form again uniform oil film in running up simultaneously, also solves due to the problem for shortage of oil burn-back copper sheathing.
This utility model advantage is:
This utility model can increase intensity and the lubricant effect of cross head pin of compressor; when reducing machine stop times and the operation post of compressor; greatly reduce the discharge capacity putting waste gas; directly reduce the pollution to surrounding; simultaneously because the minimizing of compressor maintenance number of times; also reduce the greasy dirt negative effect to post environment during maintenance, also improve production economy benefit simultaneously.
