Abstract
The invention discloses an oil-gas lubrication method. The method comprises the steps that first, a PLC control system controls an entire oil-gas lubrication process and is sequentially connected with an oil pump, an electromagnetic valve, a distributor, an oil and gas mixer, a lubrication part and an oil return box; second, an oil box is connected with the oil pump; third, an air compressor is connected with the oil and gas mixer through a filter. The oil-gas lubrication method has the advantages that oil consumption (1/8-1/10 of that of oil-mist lubrication) is low, the adaptability (150-680 cst/40 DEG C) to lubricating oil viscosity is wide, oil mist conveying capacity (conveying air pressure is 2-10 bar, and air flow speed is 30-80 m/s) is high, conveying distance (capable of achieving 100m) is long, the sealing effect on a bearing is good (the positive pressure in the bearing is 0.3-0.8 bar), the service life of the bearing is long (the service life is prolonged by 2-4 times), emission of oil mist is avoided, and the environment is not polluted, thereby having high popularization value.
Description
Technical field
The invention belongs to mechanical equipment of steel rolling field, relate to a kind of mechanical equipment of steel rolling oil-air lubrication method, be particularly suited for the lubricated of cold-rolling equipment bearing.
Background technique
Along with scientific and technical high speed development, cold rolling industry is in order to boost productivity and to reduce costs, more and more higher to the requirement of raising rolling mill speed.Therefore lubrication technology is as effective solution equipment attrition, extension device Mean time to failure, significantly reduces the effective means of cold-rolling equipment standby redundancy consumption.The bearing lubrication application oil mist lubrication of original technology cold-rolling equipment, and there is significantly deficiency in oil mist lubrication:
1, oil consumption high (be oil-air lubrication 8～10 times), lubricant oil cannot reclaim, and can not realize fixed amount of oil;
2, low to lubricating oil viscosity adaptability, only adapt to low viscosity (150cst/40 ℃) lubricant oil, when oil viscosity is too high, need to heat;
3, mist of oil conveying capacity is low, fed distance short (≤20m);
4, the overvoltage little (≤0.02bar) forming in bearing support, poor to the sealing effect of bearing;
5, when work in, has 30～50% mist of oil and is discharged in air, and befouling environment, is harmful to health.
Summary of the invention
Problem to be solved by this invention is, overcome the deficiencies in the prior art, a kind of oil-air lubricating device is provided, this device has that oil consumption is low, wide to lubricating oil viscosity adaptability, mist of oil conveying capacity is strong, and fed distance is long, good sealing effect, bearing long service life to bearing, do not have mist of oil to discharge the advantages such as free from environmental pollution.
This method solves its technical problem and takes following technological scheme to realize:
A kind of oil mist lubrication method, it is characterized in that: undertaken by following step, PLC control system is according to the Operational Limits of setting, start oil pump, lubricant oil is sent to distributor by solenoid valve, and lubricant oil is through distributor accurate measurement and distribution, deliver to oil-gas mixer, air compressor is transported to oil-gas mixer after pressurized air is filtered simultaneously, synthetic oil-air state in oil-gas mixer, and gas stream constantly realizes effectively lubricated to lubricant housings fuel feeding; Air-flow can also effectively reduce the temperature of bearing; The overvoltage that oil gas forms in bearing, has good seal action, can prevent that emulsified liquid and booty from entering bearing support; The oil-collecting device of bearing can reclaim lubricant oil, and the lubricant oil of recovery is got back to oil sump tank by pipeline.
Beneficial effect of the present invention:
Because the present invention has adopted oil-air lubrication method, overcome the deficiency of original technology, can accurate quantification oil supply, oil-air lubrication method has oil consumption low (be oil mist lubrication 1/8～1/10), almost adapt to the lubricant oil of all viscosity (150～680cst/40 ℃), oil gas conveying capacity is strong (carries air pressure 2～10bar, airspeed 30～80m/s), fed distance long (can reach 100m), sealing (forming the overvoltage of 0.2-0.3bar in bearing) to bearing effective and working life (life-span is improved 2～4 times) of having improved bearing, do not have mist of oil to discharge free from environmental pollution grade for clear superiority, therefore oil-air lubrication method has higher promotional value.
