Abstract
The invention discloses a fan rotor self-lubricating method. A fan spindle adopts a plasma spraying Ni coated microngraphite and graphene coating. The coating prepared by adopting the method attaches to the surface of the fan spindle to play a lubricating role, and frictional resistance can be remarkably reduced.
Description
Technical field
The present invention relates to antifriction technical field, particularly relate to a kind of fan rotor self-lubricating method.
Background technology
Metallurgic fan machinery is due to the impact of working environment, and the most unavoidable being in operation is mixed into solid particle, some
Even work under granule density environment, as the aerator of breeze roasting is operated in the gas that iron dust containing amount is the highest,
Containing substantial amounts of dust and Ore dust granules, the high temperature furnace that iron-smelting furnace blower fan is transported in the air of Mine Ventilator conveying
Gas contains lime-ash tar etc..Result according to relevant industries association statistics shows, occupy China's nearly half of blower fan total amount is
The conveying gas-solid two-phase mixture blower fan containing particle dust.
Track and the track of gas motion that dust and granule move at blower interior make a big difference, and it is because of contained powder
The difference of dirt grain graininess, the levels of granule and quality and the internal structure of runner, the difference in gas motion flow field and
There are distinct movement locus and characteristic.Solid element that solid particle is static with blower fan at the volley and the leaf of rotation
There is collision, rebound, rub, wear and tear and deposition problems in wheel component, so can badly influence the dynamic balancing of draught fan impeller, greatly
Add greatly the amplitude of rotor, and injure the reliability of blower fan, safety and service life.
In the departments such as such as water power thermoelectricity, the energy transport of other industrial circles, coal mining, draught fan impeller weares and teares and turns
The problem such as flutter failure of son exists the most widely, and the problem such as the fretting wear of turbomachine and rotor oscillation destruction has caused
The highest attention of related personnel.Metallurgic fan machinery great majority are all that load is huge, and long-term work is in rugged environment, because of
The fault of rotor main shaft is also frequently there is, among these in this in addition to the excessive wear of fan rotor impeller blade can occur
The problem such as the excessive wear mainly including main shaft and the impact failure brought due to reasons such as fan vibrations.
Summary of the invention
It is an object of the invention to propose a kind of fan rotor self-lubricating method, it is possible to reduce the frictional resistance of main shaft, subtract
Its abrasion few.
For reaching this purpose, the present invention by the following technical solutions:
A kind of fan rotor self-lubricating method, it uses plasma spraying Ni cladding micron graphite and graphite at blower fan main shaft
Ene coatings.
Coating of the present invention is that Ni cladding micron graphite mixes with Graphene coating.Preferably, described weight ratio
For (3-5): 1, preferably 4:1.
Described mixing is to use planetary ball mill and centrifugal spraying granulator coating to be dusted.Its technique includes:
(1) Ni is coated with micron graphite granule and Graphene ball milling at least 5 minutes on planetary ball mill；
(2), when ball milling stops first 5 minutes, add organic binder ball milling, obtain suspension；
(3) suspension is carried out mist projection granulating, obtain Ni cladding micron graphite and Graphene agglomerated particle.
Described Ni cladding micron graphite is sprayed to blower fan master with Graphene agglomerated particle by plasma spraying by the present invention
On axle.Described plasma spraying, its electric current is 400-700A, and voltage is 30-70V, main gas argon flow amount 50-140L/min, send
Powder speed 25-60g/min.Preferably, electric current is 550A, voltage 30V, argon flow amount 50L/min.
Ni of the present invention is coated with micron graphite granule, is existing product, and those skilled in the art can pass through market
It is commercially available, it is also possible to prepare according to the method for prior art.The present invention no longer limits with regard to it.
The coating of the present invention, in process of friction and wear, graphite constantly separates out from nickel bag graphite granule, at tangential masterpiece
Use lower flowing, ditch dug with a plow can be played the effect of filling and leading up, thus the wearability of main shaft can be improved.And the Graphene added, more suitable
Sliding, it is attached to main shaft surface, reduces its frictional resistance.
The coating that the present invention prepares is attached to blower fan main shaft surface, plays lubrication, and friction resistance can be greatly reduced
Power.
Detailed description of the invention
Technical scheme is further illustrated below by detailed description of the invention.
Embodiment 1
Planetary ball mill and centrifugal spraying granulator is used to be dusted by coating material.Its technique includes:
(1) Ni is coated with micron graphite granule and Graphene ball milling at least 5 minutes on planetary ball mill；
(2), when ball milling stops first 5 minutes, add organic binder ball milling, obtain suspension；
(3) suspension is carried out mist projection granulating, obtain Ni cladding micron graphite and Graphene agglomerated particle.
By plasma spraying, described Ni cladding micron graphite is sprayed on blower fan main shaft with Graphene agglomerated particle.Institute
Stating plasma spraying, its electric current is 550A, voltage 30V, argon flow amount 50L/min.
Coating on described blower fan main shaft, it plays self-lubricating solid effect.
Comparative example 1
Omitting the Graphene of embodiment 1, remaining is same as in Example 1.
Comparative example 2
Ni being coated with micron graphite and replaces with micron graphite, remaining is same as in Example 1.
The coating of comparative example 1-2, can play lubrication equally, but described lubricant effect is slightly worse, simply compared to not containing
The main shaft of coating, improves.Lubricant effect comparative example 1-2 to be substantially better than of embodiment 1, and wear time is long, plays profit
The sliding time is the most significantly longer.That is, 3 kinds of material mixing of the present invention, play synergism.
