Technical field
The present invention relates to a kind of stuffing box chamber; This stuffing box chamber be a kind of for the machine oil that do not make large ship and various actuating device because of installing at combustion chamber generated contaminant matter (internal heat, gas, sewage gas etc.) the impaired comprehensive sealing that uses (shielding the coal G&O simultaneously) in the process that is starting engine in the oil recovery engine internal; Be particularly related to a kind of high efficiency stuffing box chamber of new ideas; This stuffing box chamber can shield the pollutant substance of the burning air chamber that in the engine combustion chamber, produces effectively; Untainted bulk oil is all regained, thereby prevented the waste of a large amount of machine oil of discarding in the past, realize that simultaneously the slyness work of engine and life-span prolong.
Background technology
Stuffing box chamber in the past; Because can not shield the sewage gas that in the outburst-exhaust process of the engine of large ship, produces fully; So the machine oil that will polluted or might be polluted by sewage gas by sewage gas, it is discarded outward all to drain into engine, keeps the cleanliness factor of whole machine oil in this way.Therefore, caused to drain into engine outward waste and the consequent environmental pollution etc. of discarded a large amount of oil, the infringement of numerous accumulations of ahead of estimate has taken place.
That is, in the engine for boat cylinder, be responsible for compression and explosive strength piston on piston rod 220 connected vertically pass to the strength of generations on the bonded assembly pipe link of bottom.And, the powerful bent axle that promotes to transfer this straight line strength to circular movement of pipe link, the force of inertia that takes place this moment promotes piston rod 220 again to top, make piston compression and combustion chamber once more.The engine that carries out continuously through above-mentioned motion will be driven.
At this moment; In the oil recovery engine internal of large ship, the engine by plural number (6,8,12,18 inflators etc.) individual cylinder and piston constitute carries out in the process of above-mentioned action continuously, changeably; The pollutant substances 40 such as internal heat, gas and sewage gas that in engine top combustion chamber outburst process, take place; Pass on utensil along power, be penetrated into Mechanical Driven chamber, bottom, promptly in the crankcase 210.These not only dirty machine oil 50, and influence the life-span and the performance of mechanical component part.
In these continuous actions; Stuffing box chamber shell 100 is provided with around piston rod 220 surfaces of upper and lower straight reciprocating motion; And, on the top of stuffing box chamber shell 100, the sludge removal means having 10 and the shroud of gas means 20 that are provided with layer by layer; Not only shield and burning internal heat and the high pressure gas that air chamber 200 takes place, and remove attached to pollutant substances 40 such as piston rod 220 lip-deep sewage gases.The bottom of stuffing box chamber shell 100 is to shield machine oil 50 layer by layer through oil scraper piston ring (Oil Scraper Ring) to burn in the air chamber 200 along the inflow top, surface of piston rod 220, is recovered to again in the fuel tank in the downside crankcase 210.Stuffing box chamber shell 100 is devices of plot engine safety and slick and sly work, life-span prolongation.
In the stuffing box chamber 100 of large ship engine in the past; Be provided with the sludge removal means having 10 that is called scraping ring (Top ScraperRing) and be called the shroud of gas means 20 of pipe ring (segment ring, Sealing Ring) and the oil strain means 120 that are called oil scraper piston ring (Oil Scraper Ring), 120-1 and constituting.These devices are that countless nonmetallic ring and becket are with spring 105 stack-mounteds; Wherein above-mentioned nonmetallic ring is the various foreign substances of the high heat that takes place when being used to remove or shield engine work or gas, sewage gas or not burning, and above-mentioned becket is to be used for filtering or indispensable machine oil 50 during the work of shielding engine.
And, be provided with sludge removal means having 10 on the top of above-mentioned stuffing box chamber shell 100, be used for removing the highest sewage gas of objectionable impurities proportion attached to the external diameter of the piston rod that pumps 220.And the lower end of above-mentioned stuffing box chamber shell 100 is provided with successively with a plurality of stages and constitutes and shroud gas or internal heat are the shroud of gas means 20 of purpose, and air chamber 200 inflows of generated contaminant matter 40 in the crankcase of filling machine oil 210 are being burnt in shielding.
And; The bottom of stuffing box chamber shell 100 is provided with multistage oil strain means 120; 120-1; These oil strain means 120,120-1 can filter and shield the inflow to the top combustion chamber of the oil that moves along the continuous up-and-down movement of piston rod 220, and the objectionable impurities that in long-time operation process, does not also make machine oil burnt air chamber 200 is polluted.
Be installed in around the piston rod 220 that moves up and down continuously and be arranged on engine burn in the middle of air chamber 200 and the crankcase 210 the above-mentioned sludge removal means having 10 of stuffing box chamber shell 100 in-to-ins (TopScraper Ring) and high heat or internal heat and, shroud of gas means 20 and the oil strain means 120 that constitute by foundation ring 220 and oil strain ring 121; What 120-1 etc. were exquisite contacts at piston rod 220 is lip-deep; Be that the ultraprecise processed goods that improper abrasion are slided can not take place; These are basis functions separately, make with the material of strictness screening, special invention form.
Because of pollutant substances 40 such as the continuous gas that comprises Gao Re and internal heat that produces of engine for boat work, sewage gases; After being drained into the contour part of ring by sludge removal means having 10 (Top scraper ring) and shroud of gas means 20 (Gas sealring), through being discharged to the engine outside to the stuffing box chamber shell 100 outside a plurality of greasy filth discharge orifices 108 that connect.Though the machine oil in the crankcase 210 constantly flow into top burning air chamber 200 along the up-and-down movement of piston rod 220; But the oil strain means 120 of the stage that continuous process is provided with; 120-1 promptly goes up in the process of 8 oil strains of stack-mounted with ring 121 at foundation ring 122 (Base Ring), and shielding machine oil 50 is penetrated into and burns in the air chamber; And, be recycled to again in the fuel tank (Oil Sump) of bottom crankcase 210 through a plurality of oily recovery holes 110 in the perforation of stuffing box chamber shell 100 internal vertical.
But the removal means 1020 that are provided with on the stuffing box chamber shell 100 in engine for boat in the past can not shield the sewage gas or the pollutant substances such as gas, internal heat 40 of trickle pulverulence fully, are a kind of non-efficient structures.Therefore; Be provided with multistage oil strain means 120 in the bottom, the pollutant substance 40 of infiltration a great deal of reaches above-mentioned multiple step pattern oil strain means 120 in the space of 120-1; The machine oil 50 of oil strain means 120-1 on being positioned at topmost among the 120-1; Contaminated or think might be contaminated, then all discharge said engine oil 50, can not utilize again.
