Compared with prior art, the beneficial effects of the present invention are:
The present invention provides rolling oil system for rail, passes through the lubricating process such as concentration, flow, the pressure of injection lubricating fluid
The determination of parameter is effectively reduced roller consumption and power consumption, improves Rail Surface quality.Using net circulating water direct-furnish, construction is reduced
The expense of water station.Using the input of switch valve control lubricating oil, when not steel rolling, turns off the switch valve, reduces lubrication oil consumption.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure: 1- fuel tank 2- metering pump 3- flow control valve 4- static state oil-water mixer 5- flowmeter 6- switch valve
The scene 7- net circulating water pipeline 8- check valve 9- return pipe.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawings of the specification, it should be noted that implementation of the invention is unlimited
In the following embodiments and the accompanying drawings.
See Fig. 1, a kind of steel rail rolling lubricating arrangement, including fuel tank 1, metering pump 2, switch valve 6, flowmeter 5, static grease
Mixer 4, flow control valve 3, water system is using live clean circulating water pipeline direct-furnish mode, and live net circulating water pipeline 7 is through flowing
Adjustable valve 3 is connect with static 4 water inlet end of oil-water mixer, and flow control valve 3 uses ZDLP type electronic type to control water flow.
Fuel tank 1 is connect through switch valve 6 with the oil inlet end of static oil-water mixer 4 by piping connection metering pump 2, metering pump 2, static oil
The outlet of water mixer 4 is corresponding with rail lubrication surface, and stoste that two systems are confessed, water are in static oil-water mixer 4
Rail lubrication surface is ejected by spraying system after being sufficiently mixed.Flowmeter 5, flow are equipped between flow pump and switch valve 6
Count 5 front ends setting pressure switch.To prevent water from backflowing, it is arranged between static oil-water mixer 4 and flow control valve 3 unidirectional
Valve 8, meanwhile, flowmeter and pressure gauge can be set on net circulating water pipeline 7 at the scene, to facilitate the flow and pressure of detection water purification
Power.
Wherein, metering pump 2 is two, and a-worker-a-backup, two metering pumps 2 are connect with fuel tank 1 respectively, and metering pump 2 is using change
Frequency speed-regulating controling mode reaches the function of accurate control output flow by control revolving speed.Switch valve 6 and metering pump 2 it
Between be equipped with return pipe 9, return pipe 9 is connected with fuel tank 1, once rail does not need to lubricate, then stoste pass through return pipe 9 return to oil
Case 1.Fuel tank 1 is with level sensing and heating device.
A kind of steel rail rolling lubricating method, the stoste that water purification and fuel tank 1 in live net circulating water pipeline 7 provide is through static state
After oil-water mixer 4 mixes, lubricating fluid is formed, injection of lubrication liquid to rail lubrication surface is rail lubrication；Live net circulating water
The control of 7 pressure of supply water of pipeline is controlled in 15-20L/min, stoste output pressure in 0.6- in 0.3-0.7Mpa, water flow control
1.5Mpa；Stoste output flow is controlled in 0.2-2L/min；The control of lubricating fluid concentration lubricates flow quantity in 1%-11% after mixing
Control is in 0.8-1.2m3/h.Stoste output pressure is greater than pressure of supply water, to prevent water from entering oil pipe line system.
It can reach the effect of rolling lubrication using above-mentioned lubricating method, reduce milling train power consumption 3%, reduce roller consumption 5%, rail
Waste wood reduces by 2% after surface quality improves, since this system investment ton steel cost increases control in 2 yuan/ton.
According to injection concentration requirement, by the frequency converter revolving speed and control 3 aperture of flow control valve of control metering pump 2, thus
Control oil, water flow proportion.According to steel rolling timing, the switch valve 6 on control oil pipe road is opened in steel rolling, oil feeds injection system
System, switch valve 6 is closed when not steel rolling, to save the use of rolled lubricating oil.In view of water system control flow control valve 3 exists
Reach stable state in control process and need the response time, be not easy frequently to be opened and closed, so after regulating flow in process of production always
It supplies water, is shut down if any the long period and close water supply pipe switch valve 6 then to save water.
The course of work are as follows: metering pump 2 (a-worker-a-backup) is exported lubricating oil in fuel tank 1 by setting flow, live water pipeline
In water flow output is controlled by flow control valve 3, the two is mixed into certain density lubricating fluid in static oil-water mixer 4
It is output to edger roll oil site.
