Abstract

The invention discloses a fan rotor self-lubricating method. A graphene nickel-based composite coating with the thickness of 20-30 mum is electroplated on the surface of a fan spindle. The composite coating prepared by the fan rotor self-lubricating method is attached to the surface of the fan spindle, the lubricating effect is achieved, and therefore, frictional resistance can be reduced greatly.

Description

A kind of fan rotor self-lubricating method
Technical field
The present invention relates to antifriction technical field, more particularly, to a kind of fan rotor self-lubricating method.
Background technology
Metallurgic fan machinery is mixed into solid particle due to the impact of working environment, often unavoidable being in operation, some Even work under granule density environment, the aerator of such as breeze roasting is operated in the very high gas of iron dust containing amount, The in the air of Mine Ventilator conveying contains substantial amounts of dust and Ore dust granules, the high temperature furnace that iron-smelting furnace blower fan is transported Gas contains lime-ash tar etc..Show, occupy the nearly half of China's blower fan total amount is according to the result of relevant industries association statistics The gas-solid two-phase mixture blower fan containing particle dust for the conveying.
The track that dust and granule move in blower interior and the track of gas motion make a big difference, and it is because of contained powder The internal structure of the difference of dirt grain graininess, the levels of granule and quality and runner, the difference in gas motion flow field and There are distinct movement locus and characteristic.The solid particle leaf with static solid element in blower fan and rotation at the volley There are collision, bounce-back, friction, abrasion and deposition problems in wheel component, so can badly influence the dynamic balancing of draught fan impeller, greatly Increased greatly the amplitude of rotor, and injure reliability, safety and the service life of blower fan.
In other industrial circles such as department such as the transport of water power thermoelectricity, the energy, coal mining, draught fan impeller weares and teares and turns The problems such as flutter failure of son, all widely exists, and has caused the problems such as the fretting wear of turbomachine and rotor oscillation destroy 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 Also frequently there is the fault of rotor main shaft in addition to the excessive wear that meeting occurs fan rotor impeller blade, among these in this The main excessive wear including main shaft and due to the reason band such as fan vibration impact failure the problems such as.
Content of the invention
It is an object of the invention to proposing a kind of fan rotor self-lubricating method, the frictional resistance of main shaft can be reduced, subtract Its abrasion few.
For reaching this purpose, the present invention employs the following technical solutions:
A kind of fan rotor self-lubricating method, it has the Graphene of 20-30 μ m thick Ni-based in blower fan main shaft electroplating surface Composite deposite.
Preferably, the Graphene nickel-base composite coat that described blower fan main shaft surface has, is prepared via a method which Arrive:
(1) blower fan main shaft is activated 20-30s with the dilute hydrochloric acid of 1-3wt%；
(2) nickel plate is adopted to be anode, the blower fan main shaft of activation is negative electrode, is 4-6 in ph, and temperature is 40-60 DEG C, negative electrode electricity Current density is 1.5-3a/dm2Under conditions of electroplated, the consisting of of described composite plating bath:
Nickel sulfate 140-160g/l, Nickel dichloride. 25-40g/l, boric acid 20-30g/l, sodium sulfate 10-15g/l, Graphene 0.1-0.5g/l, gum arabic powder 0.01-0.1g/l.
In the composite plating bath of the present invention, nickel sulfate is the main salt of nickel-plating liquid, concentration highest in the plating solution, electric conductivity Well it is allowed to using higher electric current density, deposition velocity, brightness and the Surface flat of coating, concentration of nickel sulfate can be accelerated Preferably, coating crystallization is careful for low solution dispersibility.
In the nickel-plating liquid of sulfuric urea, in order to not make anodic passivity it is necessary to the presence of chloride ion, otherwise in nickel-plating liquid Nickel ion will be remarkably decreased, and the electric conductivity of solution reduces, and add Nickel dichloride. can promote anodic solution, improve the conduction of solution Property, and the dispersibility of plating solution can be improved.
Boric acid is mainly used as buffer agent in nickel plating, for stablizing the ph value of electrolyte.Sodium sulfate can increase plating solution Electric conductivity, improves the dispersibility of plating solution, improves quality of coating.
Gummi arabicum pulveratum can be dissolved in water, has backbone, Graphene can be kept uniform in the plating solution as dispersant Dispersion, can use in acid condition.
The thickness of multiple plating of the present invention is about 20-30 μm, and its hardness significantly improves compared with matrix and nickel coating, exceedes 500hv0.2.Meanwhile, adding Graphene in composite deposite makes crystal grain be refined, and average grain size is from the 40nm of pure ni Drop to 20nm.
The composite deposite of the present invention makes coefficient of friction and wear rate reduce simultaneously, has relatively low coefficient of friction, simultaneously There is the wearability more excellent than cr coating.Under each load, wear rate reduces by more than 50% than matrix.
The composite deposite that the present invention prepares is attached to blower fan main shaft surface, plays lubrication, can be greatly reduced and rub Wipe resistance.
