Abstract
The utility model discloses a kind of main fuel tank deironing special purpose device, comprise support, equidistant on support many permanent-magnet magnetic rod iron cores are installed.The utility model can remove the impurity such as institute's iron content, cobalt, nickel, chromium in oil efficiently, purification oil residue is rapid, after making maintenance or newly, set lubricating oil system corresponding shortening cycle time is installed, purifies thorough efficiency high, ensure that the safe and reliable operation of unit.The utility model structure is simple, reasonable in design, custom-designed for the specific question of turbo-engine lube, de-ferrous effect is very remarkable, it thoroughly can solve the impact that the iron tramp that contains in turbo-engine lube brings, improve the purification ratio of oil, prevent the steam turbine set diameter of axle and bearing shell to scratch problem, regulating system is stablized, Working Life of Lubricating Oil extends, and ensure that the safe and reliable operation of unit.
Description
One, technical field
The utility model belongs to deironing device technical field, is specifically related to a kind of main fuel tank deironing special purpose device.
Two, background technique
The clean degree of turbine oil system is the key factor affecting unit safety and economical operation, and along with 300, the operation in succession of 600MW and above large-capacity steam turbine unit, in power production process, corresponding raising is required to oily turbidity test.Control lubricant pollution rationally and effectively and be still the key technical problem that Turbine Safety and economical operation face.Wherein lubricant oil deterioration most important factor is exactly the pollution that the pollutants such as metal particle cause; metal particle can enter bearing with lubricant oil; cause bearing shell, journal wear; and the wearing and tearing of this part particle to bearing shell, axle journal are continuously just; and the particle that axle journal and bearing wear produce brings again further unstable wear in oil into; cause vicious circle; metal granule has catalysis to lubricant oil simultaneously; accelerate the oxidation deterioration of fluid; the life-span iron particle reducing fluid makes fluid oxidation rate accelerate 10 times, and copper particle makes fluid oxidation rate accelerate 30 times.
In order to solve this difficult problem of lubricating oil system deironing, people progressively can only remove by the method for circulating oil filtering usually to these fine impurities usually, but needed time is long, to being less than the invisible molecule of below 60um, common oil filtering unit is difficult to removing, and de-ironing efficiency is very low, there is no real process problem, also make process complications, add cost, do not receive welcome very much.
Three, summary of the invention
It is simple, reasonable in design that the purpose of this utility model is to provide a kind of structure, can effectively remove lubricant oil molecule rapidly, avoids causing wearing and tearing to bearing, prevents the main fuel tank deironing special purpose device that oil ageing is rotten.
For achieving the above object, the technical solution adopted in the utility model is: this device comprises support, is characterized in: equidistantly on support be provided with many permanent-magnet magnetic rod iron cores.
During use, the utility model is directly placed in the main fuel tank of lubricating oil system that (main fuel tank is a terminal of lubricant oil, the lubricant oil of all devices all can be got back in main fuel tank, and then from main fuel tank, get back to each equipment needing lubrication), the encapsulation magnetic field of lubricant oil by being set up by permanent-magnet magnetic rod iron core, Ferrous particles wherein screens and firmly pins by permanent-magnet magnetic rod iron core, realize the overall magnetic purification of lubricating oil system, institute's iron content in oil can be removed efficiently, cobalt, nickel, the impurity such as chromium, purification oil residue is rapid, after maintenance can be made or newly, set lubricating oil system corresponding shortening cycle time is installed, purify thorough efficiency high, ensure that the safe and reliable operation of unit.The utility model structure is simple, reasonable in design, custom-designed for the specific question of turbo-engine lube, de-ferrous effect is very remarkable, it thoroughly can solve the impact that the iron tramp that contains in turbo-engine lube brings, improve the purification ratio of oil, prevent the steam turbine set diameter of axle and bearing shell to scratch problem, regulating system is stablized, Working Life of Lubricating Oil extends, and ensure that the safe and reliable operation of unit.The utility model normally can work under the differential pressure action of maximum service pressure 1Mpa, and does not damage.Meanwhile, under the condition that serviceability temperature is not more than 130 degree and is not subject to severe impact, working life can reach more than 30 years.
Four, accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side view of the present utility model.
Five, embodiment
As shown in the figure, the utility model comprises support 2-2, and support 2-2 can be rectangle or circle.Equidistant on support 2-2 many permanent-magnet magnetic rod iron core 2-1 are installed.Support 2-2 can be upper and lower two, and permanent-magnet magnetic rod iron core 2-1 is arranged between upper and lower two support 2-2, to improve the soundness of permanent-magnet magnetic rod iron core 2-1 on support 2-2.Support 2-2 is made up of Bai Gang, and permanent-magnet magnetic rod iron core 2-1 just can directly be absorbed and fixed between upper and lower two support 2-2, and dismounting is got up simple and convenient.Meanwhile, in order to prevent permanent-magnet magnetic rod iron core 2-1 from mutually inhaling together, the spacing between permanent-magnet magnetic rod iron core 2-1 is 100-150mm.The magnetic material that permanent-magnet magnetic rod iron core 2-1 adopts is rare-earth Nd-Fe-B, and its magnetic intensity is 5500-6000 Gauss, can form high gradient and close Bipolar field, firmly can pin impurity, reach best de-ferrous effect.
