Abstract
The invention discloses a wire oil-air lubrication control method. A device body is not changed. The method comprises steps of step1, setting an initial position of an electromagnetic directional valve to be in an energized state; step 2, starting a motor to drive a gear wheel to rotate, setting up oil pressure on a main oil line, limiting safe oil pressure by using an overflow valve and removing impurities in lubricating oil by using a filter; step 3, detecting whether the oil pressure reaches 6MPa within 20 seconds; step 4, proving that all lubricating points do not leak and are not stuck if the oil pressure reaches 6MPa, feeding the pressure oil to an oil-air mixer through a distributor, mixing the pressure oil with compressed air, feeding the mixture to lubricating points, completing the loading process, shutting down the electromagnetic directional valve, stopping the gear pump, unloading the oil pressure of a pipeline, and sending fault signals and shutting down rolling lines if the oil pressure fails to reach 6MPa; step 5, delaying for 5 seconds till the lubrication is completed; and step 6, energizing the electromagnetic directional valve, delaying for 30 seconds, restarting the step 2 and completing the circulation. By the aid of the method, the problem of fault time caused by the fact that rolling lines are shut down due to long loading time of an oil-air pump is solved.
Description
Technical field
The invention belongs to the oil-air lubrication control mode and improve, solve the method for mechanical failure by changing the oil gas control flow.
Background technique
In the bearing lubrication of fast mill, oil-air lubrication is current a kind of lubricating system of generally using.At wire rod production line, petroleum system is mainly used in the lubricated of rolling machine guide and guard, transmission shaft catcher, rolling bearing and kink bearing.And in the actual production process, some or several distributors are stuck or leak, and this can make lubricant oil leak out from these several fault distributors, and oil circuit pressure is set up not, lubricant oil can not mean allocation to each distributor, cause lubrication trouble.This can by guaranteeing the oil product turbidity test, prevent that dirt particle from stopping up distributor and solving; The pressurized air anti-channeling enters working connection.This mainly is because when pump is shut down, working connection off-load, and pressurized air has the pressure of 0.6MPa all the time, if some distributors poorly sealed or wearing and tearing are slightly arranged, pressurized air will anti-channeling enter oil circuit so.So when loading, pressure oil wants first pressurized air to be extruded oil pipe just can be fed to lubricating point next time, increase pressure rising time, and this has just caused the pump load time long.Because the whole piece rolling line contains up to a hundred distributors, some distributor is positioned under the hot environment, and sealing easily damages, so want investigation time-consuming, the effort that is which distributor is out of order.
Summary of the invention
The purpose of this invention is to provide a kind of wire rod oil-air lubrication controlling method, solve the oil gas pump load time long and cause rolling line to shut down the problem of fault time that causes.
For achieving the above object, technological scheme of the present invention is in the situation that do not change apparatus body and make, and its concrete steps are as follows:
The first step: the initial bit of solenoid directional control valve is set as to get electricity condition;
Second step: the running of starting electrical machinery driven gear pump, set up oil pressure at working connection, relief valve limits safe oil pressure, and filter is removed lubricated well cuts;
Detect oil pressure in the 3rd step: the 20S and whether reach 6MPa;
The 4th step: if reach 6MPa, illustrate that each lubricating point is without leakage, stuck, pressure oil is sent into lubricating point after being fed to oil-gas mixer and pressurized air mixes by distributor, and loading procedure is finished, and solenoid directional control valve dead electricity, gear pump shut down, the off-load of pipeline oil pressure; If do not reach 6MPa, send trouble signal, rolling line is shut down;
The 5th step: postpone 5S, wait for lubricated finishing;
The 6th step: solenoid directional control valve gets electric, postpones 30S, again arrives second step, finishes circulation.
Adopt wire rod oil-air lubrication controlling method of the present invention, though distributor be sealed with wearing and tearing because the P mouth is plugged, the compressibility of lubricant oil is little again, pressurized air just can not anti-channeling enter in the working connection like this; The load time of oil gas shortens to 6S by original 18S; Cause the minimizing of leakage rate owing to the shortening of load time, thereby make lubricants capacity guarantee to have reduced waste for the required oil mass of bearing normal operation.
